This study aimed to assess intraoperative complication rates and risk factors in patients who underwent surgery for tubo-ovarian abscess. A retrospective review of the medical records of 170 patients who underwent tubo-ovarian abscess surgery between January 2014 and December 2023 was conducted. Four patients were excluded due to a histopathologic diagnosis of cancer, and 166 patients were included in the final analysis. Intraoperative complications were observed in 10 (6.0%) patients, including 8 (4.8%) and 2 (1.2%) patients with bowel and bladder injuries, respectively. The included patients were categorized into complication-positive (n = 10, 6.0%) and complication-negative (n = 156, 94.0%) groups, with between groups comparisons based on demographic, clinical, and surgical characteristics. The complication-positive group had significantly higher mean age and serum c-reactive protein (CRP) levels than the complication-negative group (46.6 ± 7.4 years vs 40.6 ± 8.5 years; P = .03, and 199.2 ± 89.4 mg/L vs 112.2 ± 84.2 mg/L; P ≤ .01, respectively). Extensive surgery, such as hysterectomy with bilateral adnexectomy, was more commonly performed in the complication-positive group than in the complication-negative group (8/10 [80.0%] vs 43/156 [27.5%], P < .01). Receiver operating characteristic curve analysis identified a serum CRP level of 186.5 mg/L as the optimal cutoff for predicting intraoperative complications. Binary logistic regression analysis showed that elevated serum CRP levels (≥186.5 mg/L) (odds ratio: 7.9; P < .01) and extensive surgery (odds ratio: 11.0, P = .01) were independently associated with intraoperative complications. Our findings indicate that elevated serum CRP levels and extensive surgery are associated with increased intraoperative complication risks, which may have important implications in clinical practice, potentially informing preoperative assessments, and surgical planning.

Study Objective: Although cystectomy remains the gold standard for the surgical treatments of endometriomas, concerns about the negative effect on ovarian reserve are rising. Laser-CO 2 vaporization of endometriomas has shown encouraging data on ovarian reserve preservation, postoperative pregnancy rates, and recurrence. The aim of this study was to assess postoperative recurrence rate and pregnancy rate in patients with endometriomas managed by CO 2 fiber laser vaporization after at least 5 years following surgery., Design: Retrospective study., Setting: Italian tertiary center from October 2023 to February 2024., Patients: We included women aged >18 years who underwent laparoscopic CO 2 fiber laser vaporization for endometriomas. Age ≥40 years, previous ovarian surgery, previous salpingectomy or hysterectomy, negative histologic finding for endometriosis, or any findings of malignancy at histology were exclusion criteria., Intervention: Ovarian endometriomas were vaporized through laparoscopic CO 2 fiber laser. After surgery, patients were included in a surveillance program with periodic clinical follow-ups., Measurements and Main Results: Seventy-eight patients were included. The mean age was 33.2 ± 4.6 years, the basal anti-Müllerian hormone was 2.7 ± 1.9 ng/mL, and the median diameter of the endometriomas was 4 (3-5) cm. The median duration of follow-up was 72.5 months (67-84.5). After surgery, 65.5% (n = 36) of women with reproductive desire achieved a pregnancy, 55.6% spontaneously, and 44.4% through Assisted Reproduction Techniques, with a mean time to pregnancy of 17.7 ± 18.1 months. A Kaplan-Meier curve for the 7 patients who experienced an ipsilateral recurrence showed that the median time to recurrence was 26 months and the estimated rate of disease-free patients was 91.03% at 100 months (95% confidence interval 82.10%-95.62%)., Conclusion: CO 2 fiber laser vaporization is an effective and safe surgical treatment of ovarian endometriomas, combining the advantage of being an ovarian tissue-sparing technique with long-term postoperative recurrence rate comparable with that described in literature for the cystectomy., (Copyright © 2024 AAGL.

We present a case of tubo-ovarian abscess (TOA) caused by Clostridioides difficile (CD) in a 43-year-old female. Despite lacking a history of sexually transmitted diseases, the patient had undergone paraovarian cystectomy nine months before admission. Transvaginal ultrasonography performed eight months post-surgery revealed left ovarian enlargement, accompanied by subsequent lower abdominal pain and fever exceeding 38 °C. As oral antibiotic treatment was ineffective, the patient was admitted to our hospital. Computed tomography upon admission revealed a massive TOA. Surgical drainage of the abscess was performed, and CD was identified in the culture from the pus. The TOA was treated with a three-month course of metronidazole and oral amoxicillin/clavulanic acid. While CD is commonly associated with colitis, extraintestinal manifestations are exceptionally rare. This case represents the inaugural report of TOA resulting from CD. A literature review on abdominal and pelvic CD abscesses found that patients undergoing surgical drainage had a favorable prognosis. Therefore, surgical intervention plays an important role in the management of CD abscesses., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Japanese Society of Chemotherapy, Japanese Association for Infectious Diseases, and Japanese Society for Infection Prevention and Control.

Objective: To identify related factors that affect the ovarian reserve after laparoscopic ovarian cystectomy in patients with endometriomas., Study Design: It was a retrospective cohort study performed in a tertiary-care university hospital. A total of 409 patients with endometriomas underwent laparoscopic ovarian cystectomy between June 2014 and November 2021., Results: The demographic and operative data, including age, parity, body mass index, tumor size, operating time, and estimated blood loss were recorded. Serum anti-Mullerian hormone (AMH) levels were recorded preoperatively, as well as 10 days (immediately) and 6 months after the procedure respectively. The decrease of serum AMH level at 6 months after the surgery were 0.7 ± 1.6 ng/mL (22.5 ± 57.1 %) in the unilateral group and 1.5 ± 2.1 ng/mL (48.3 ± 65.6 %) in the bilateral group. The reduction in the serum AMH level at 10 days and 6 months after the operation were significant compared to the baseline level. The bilateral group has a significantly lower serum AMH level than that of the unilateral group in terms of 10 days and 6 months after operation (p < 0.001). Baseline serum AMH level < 2 ng/mL have shown less reduction in both 10 days group and 6 months group with odds ratio (OR) 0.36 (p = 0.01) and OR 0.264 (p < 0.001) respectively. Neither patient's age nor tumor size contributed to the decline of ovarian reserve., Conclusions: Bilaterality and pre-operative serum AMH level are the two key factors that affect ovarian reserve after laparoscopic cystectomy., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Background: Endometrioma are endometriotic deposits within the ovary. Laparoscopic management of endometriomas is associated with shorter hospital stay, faster recovery, and decreased hospital costs compared with laparotomy. The previous version of this systematic review (2008), including randomised controlled trials (RCTs) of surgical interventions for endometrioma, concluded that laparoscopic cystectomy (excision) was preferable to drainage and ablation of endometrioma. We aimed to update the evidence comparing excision with drainage and ablation for improving pain and fertility-related outcomes., Objectives: To evaluate the safety and efficacy of laparoscopic excision (cystectomy) compared with laparoscopic drainage and ablation of endometrioma in women of reproductive age., Search Methods: We searched the Cochrane Gynaecology and Fertility Group Specialised Register, CENTRAL, MEDLINE, Embase, PsycInfo, two trials registries, grey literature sources, and conference proceedings on 19 December 2022. We also checked the reference lists of relevant papers and contacted leaders in the field of endoscopic surgery for any additional trials., Selection Criteria: Eligible studies were RCTs that compared excision with drainage and ablation of endometriomas., Data Collection and Analysis: Two review authors independently assessed study eligibility, extracted data, assessed risk of bias, and applied the GRADE approach to rate the certainty of evidence., Main Results: We identified nine studies (involving 578 women) that investigated laparoscopic excision versus drainage and ablation of endometriomas measuring at least 3 cm in diameter. Participants were women of reproductive age who presented to an outpatient gynaecology clinic with pain, infertility, or both. For most outcomes, we downgraded the certainty of evidence for risk of bias due to lack of blinding and for imprecision due to low participant numbers. At up to two years after surgery, excisional surgery compared with ablative surgery may reduce the risk of dysmenorrhoea recurrence (OR 0.25, 95% CI 0.12 to 0.52; 2 studies, 140 women; low-certainty evidence;). Recurrence of dysmenorrhoea may occur in 49% of women after ablative surgery compared with 10% to 34% after excisional surgery. At up to two years after surgery, excisional surgery compared with ablative surgery may reduce the risk of dyspareunia recurrence (OR 0.09, 95% CI 0.03 to 0.22; 2 studies, 131 women; low-certainty evidence). Recurrence of dyspareunia may occur in 58% of women after ablative surgery compared with 4% to 23% after excisional surgery. At one year after surgery, excisional surgery may reduce the risk of endometrioma recurrence compared with ablative surgery (OR 0.17, 95% CI 0.09 to 0.34; 4 studies, 264 women; low-certainty evidence). Recurrence of endometrioma may occur in 37% of women after ablative surgery compared with 5% to 17% after excisional surgery. At one year after surgery, excisional surgery may reduce the need for further endometrioma surgery compared with ablative surgery (OR 0.16, 95% CI 0.07 to 0.41; 2 studies, 178 women; low-certainty evidence). Our results suggest that 32% of women require further endometrioma surgery after ablative surgery compared with 3% to 16% after excisional surgery. There may be little or no difference between excisional surgery and ablative surgery in terms of their effect on spontaneous pregnancy during the first year after surgery (OR 1.27, 95% CI 0.33 to 4.87; 3 studies, 101 women; low-certainty evidence). Five studies reported that there were no conversions to laparotomy. No studies provided data about any other surgical complications or adverse effects., Authors' Conclusions: Surgical management of endometrioma with excision (cystectomy) may be more effective than drainage and ablation for reducing painful menstrual periods, pain during sexual intercourse, endometrioma recurrence, and the need for further endometrioma surgery. However, there may be little or no difference between the techniques in their effect on subsequent pregnancy rates. We found limited evidence on the safety of excisional surgery compared with ablative surgery. Future trials should recruit adequate numbers of women and measure outcomes relating to adverse events and clinical pregnancy., (Copyright © 2024 The Cochrane Collaboration.

Background: Benign ovarian lesions in the pediatric population have variable risk of recurrence or development of metachronous lesions, leading to variations in operative approach. Our study compares outcomes with differing surgical approaches to better elucidate risk of recurrent or metachronous lesions, time to development of these lesions, and hospital length of stay to determine if one operative approach has superior outcomes. Methods: We retrospectively examined data from Indiana University Health facilities from 2002 to 2020. Patients ≤18 years old who underwent surgical management of a benign ovarian lesion were included. Patients were categorized as undergoing oophorectomy versus ovarian sparing surgery (OSS), with open and laparoscopic approaches. Significance was defined as P < .05. Results: We identified 127 patients who underwent an open ( n = 65) versus laparoscopic ( n = 55) surgical approach. Patients undergoing open surgery had a greater mean size of lesion ( P = .05) and longer length of stay ( P < .01). Complication rates ( P = .1), rates of developing a metachronous or recurrent lesion postoperatively ( P = .47), and time to formation of additional lesions were similar between groups ( P = .25). The incidence of identifying an additional lesion after surgery was 14.2% ( n = 18) in the mean time of 29.5 ± 31.6 months [SEM 7.5]. Risk of developing a metachronous lesion was similar regardless of the operative approach. Surgery for recurrent ovarian lesions was rare and occurred in only 1 case. Conclusions: Laparoscopic surgery was performed for smaller lesions and was associated with a shorter length of hospital stay. Laparoscopic and OSS was found to have no increased risk of developing metachronous lesions nor increased reoperative risk compared with traditional open and oophorectomy techniques.

Aim: to evaluate the efficacy of an integrated management approach for ovarian endometriomas using Dienogest administered both before and after laparoscopic cyst enucleation in women with infertility., Materials and Methods: The prospective, comparative clinical trial included 44 patients aged 18-35 years with ovarian endometriomas and infertility. Patients were randomly divided into two groups: the study group (20 participants) received Dienogest for six months before and after laparoscopic cyst enucleation, while the control group (24 participants) underwent laparoscopic cyst enucleation without additional hormonal treatment. Outcomes measured included: cyst size (before treatment and after six months of Dienogest administration in the study group), serum levels of anti-Müllerian hormone (AMH), antral follicle count (AFC) in both groups (before and six months after surgery), pregnancy rates, and recurrence rates of endometriomas within a 1-year follow-up., Results: Study Group: Dienogest treatment resulted in a significant reduction in cyst size before surgery. AFC and AMH levels remained stable before and after surgery. At the 1-year follow-up, 13 participants (65%) achieved pregnancy, and endometrioma recurrence was observed in 3 participants (15%)., Control Group: Six months post-surgery, AFC and AMH levels were significantly lower than pre-surgery levels. During the follow-up, 7 participants (29.2%) achieved pregnancy, and endometrioma recurrence was noted in 19 participants (79.2%)., Conclusion: The integrated management approach using Dienogest administered both before and after laparoscopic cyst enucleation has proven to be effective in improving reproductive outcomes and reducing recurrence rates of ovarian endometriomas in women with infertility.

Background: Inadequate surgical interventions can lead to serious complications such as tubo-ovarian abscesses in the upper female genital system, often resulting from untreated pelvic inflammatory disease. Pelvic inflammatory disease, caused by infections like Chlamydia trachomatis and Neisseria gonorrhoeae, leads to scarring and adhesions in the reproductive organs, with common risk factors including intrauterine device use and multiple sexual partners. Pelvic inflammatory disease primarily affects sexually active young women and can manifest with varied symptoms, potentially leading to complications like ectopic pregnancy, infertility, and chronic pelvic pain if untreated., Case Presentation: This case report presents a unique scenario involving a 17-year-old sexually inactive female who experienced concurrent tubo-ovarian abscess, acute cystitis, and pancolitis following laparoscopic ovarian cystectomy. Pelvic inflammatory disease and its complications are well-documented, but the simultaneous occurrence of acute cystitis and pancolitis in this context is unprecedented in the medical literature. The patient's presentation, clinical course, and management are detailed, highlighting the importance of considering diverse and severe complications in individuals with a history of gynecological surgeries., Conclusions: Our case report highlights the need for healthcare professionals to remain vigilant for atypical presentations of gynecological complications and emphasizes the value of interdisciplinary collaboration for optimal patient care. We encourage further research and awareness to enhance understanding and recognition of complex clinical scenarios associated with gynecological procedures., (© 2024. The Author(s).)

Ovarian endometriomas (OEs) are commonly detected by ultrasound in individuals affected by endometriosis. Although surgery was widely regarded in the past as the gold standard for treating OEs, especially in the case of large cysts, the surgical management of OEs remains debated. Firstly, OEs often represent the "tip of the iceberg" of underlying deep endometriosis, and this should be considered when treating OEs to ameliorate patients' pain for focusing on the surgical objectives and providing better patient counseling. In the context of fertility care, OEs may have a detrimental effect on ovarian reserve through structural alterations, inflammatory responses, and oocyte reserve depletion. Conversely, the surgical approach may exacerbate the decline within the same ovarian reserve. While evidence suggests no improvement in in-vitro fertilization (IVF) outcomes following OE surgery, further studies are needed to understand the impact of OE surgery on spontaneous fertility. Therefore, optimal management of OEs is based on individual patient and fertility characteristics such as the woman's age, length of infertility, results of ovarian reserve tests, and surgical background. Among the available surgical approaches, cystectomy appears advantageous in terms of reduced recurrence rates, and traditionally, bipolar coagulation has been used to achieve hemostasis following this approach. Driven by concerns about the negative impact on ovarian reserve, alternative methods to obtain hemostasis include suturing the cyst bed, and novel methodologies such as CO2 laser and plasma energy have emerged as viable surgical options for OEs. In instances where sonographic OE features are non-reassuring, surgery should be contemplated to obtain tissue for histological diagnosis and rule out eventual ovarian malignancy., Competing Interests: Declaration of competing interest The authors did not have conflict of interest to declare., (Copyright © 2024 The Authors.

Objective: To assess the prevalence of endometriosis of the appendix and the association with other pelvic localizations of the disease and to provide pathogenesis hypotheses., Methods: Monocentric, observational, retrospective, cohort study. Patients undergoing laparoscopic endometriosis surgery in our tertiary referral center were consecutively enrolled. The prevalence of the different localizations of pelvic endometriosis including appendix involvement detected during surgery was collected. Included patients were divided into two groups based on the presence of appendiceal endometriosis. Women with a history of appendectomy were excluded., Measurements and Main Results: Four hundred-sixty patients were included for data analysis. The prevalence of appendiceal endometriosis was 2.8%. In patients affected by endometriosis of the appendix, concomitant ovarian and/or bladder endometriosis were more frequently encountered, with prevalence of 53.9% (vs 21.0% in non-appendiceal endometriosis group, p = 0.005) and 38.4% (vs 11.4%, p = 0.003), respectively. Isolated ovarian endometriosis was significantly associated to appendiceal disease compared to isolated uterosacral ligament (USL) endometriosis or USL and ovarian endometriosis combined (46.2% vs 15.4% vs 7.7%, p < 0.001). Poisson regression analysis revealed a 4.1-fold and 4.4-fold higher risk of ovarian and bladder endometriosis, respectively, and a 0.1-fold risk of concomitant USL endometriosis in patients with appendiceal involvement., Conclusion: Involvement of the appendix is not uncommon among patients undergoing endometriosis surgery. Significant association was detected between appendiceal, ovarian, and bladder endometriosis that may be explained by disease dissemination coming from endometrioma fluid shedding. Given the prevalence of appendiceal involvement, counseling regarding the potential need for appendectomy during endometriosis surgery should be considered., (© 2024.

Introduction: To evaluate the effect of injecting vasopressin during laparoscopic excision of ovarian endometriomas on ovarian reserve., Evidence Acquisition: Four different databases (PubMed, Cochrane Library, Scopus, and ISI Web of Science) were searched to identify relevant studies in March 2023. We selected randomized controlled trials (RCTs) that compared vasopressin injection in the intervention group versus no injection of vasopressin in the control group among women undergoing laparoscopic cystectomy of ovarian endometriomas. The main outcomes were the amount of bleeding, number of coagulation events, and levels of serum anti-Müllerian hormone (AMH) and follicle-stimulating hormone (FSH). The available data were extracted and analyzed in a meta-analysis model using RevMan software., Evidence Synthesis: Seven RCTs, involving a total number of 478 patients, were included in our study. The vasopressin group had significantly reduced blood loss amount and number of coagulation events compared to the control group (P=0.004 and P=0.005). There was a significant improvement in the AMH levels within 6 months after surgery in the vasopressin group (MD=0.52, 95% CI: 0.11, 0.93, P=0.01). In addition, the FSH levels within 6 months after laparoscopic cystectomy were significantly reduced with vasopressin injection., Conclusions: Vasopressin injection during laparoscopic cystectomy of ovarian endometriomas is effective in reducing blood loss amount and frequency of coagulation, as well as protecting the ovarian reserve. More trials are encouraged to confirm our findings.

Pediatric and adolescent ovarian lesions are common and are frequently managed by both pediatric surgeons and pediatric and adolescent gynecologists. During the 2023 American Academy of Pediatric Section on Surgery meeting, an educational symposium was delivered focusing on various aspects of management of pediatric and adolescent benign and malignant masses, borderline lesions, and fertility options for children and adolescents undergoing cancer therapies. This article highlights the discussion during this symposium., (Copyright © 2024 Elsevier Inc. All rights reserved.)

This study aimed to compare the impact of ablation and cystectomy for ovarian endometrioma on ovarian reserve, recurrence rates, and pregnancy rates. Databases were searched for studies reporting ovarian reserve (measurement of anti-müllerian hormone [AMH] only), recurrence rates, and/or pregnancy rates after cystectomy and ablation for ovarian endometrioma. Six randomized clinical trials and five prospective cohort studies were included in this meta-analysis. All included studies had a low risk of bias. After ablation, weighted mean difference (WMD) between post- and pre-operative AMH values was - 0.40 (95% confidence interval [CI]: -0.61 to -0.19, p = 0.0002, I 2  = 0%). After cystectomy, the WMD of AMH was - 1.08 (95% CI: -1.34 to -0.82, p < 0.00001, I 2  = 48%). The intergroup comparison revealed that pre-operative AMH values were similar between the two groups, but post-operative AMH was significantly higher in the ablation group (WMD: 0.38, 95% CI: 0.13 to 0.63, p = 0.003, I 2  = 3%). Subgroup analysis showed that the favorable effects of ablation compared to cystectomy are evident after three months of operation, in a bilateral setting, or with the laser ablation method. Overall recurrence rate (risk ratio [RR]: 1.51, 95% CI: 1.08 to 2.12, p = 0.02, I 2  = 0%) and one-year recurrence rate (RR: 2.36, 95% CI: 1.30 to 4.31, p = 0.005, I 2  = 0%) were significantly higher in the ablation group than in the cystectomy group. Pregnancy rates were similar between the two groups (odds ratio: 1.18, 95% CI: 0.92 to 1.52, p = 0.20, I 2  = 72%). These results demonstrate that ablation could result in a smaller serum AMH decrement than cystectomy, but the recurrence rate could be higher after ablation., (© 2024.

Objective: To compare the short and long-term benefits (the length of hospital stay, surgical complications, and early clinical improvement) of adding early ultrasound-guided drainage to broad-spectrum antibiotic treatment., Methodology: Patients undergoing tubo-ovarian abscess treatment between January 2017 and June 2022 in a tertiary hospital were retrospectively evaluated. Of the patients studied, 50 subjects were treated with antibiotics alone and 63 underwent guided drainage. Twenty-one individuals underwent early drainage within 72 hours of admission, and 42 underwent guided drainage after this period., Results: There was no statistical difference in the length of hospital stay between the groups simultaneously, averaging 6.4 days for the controls, 5.1 days for the early drainage group, and 9.6 days for the late drainage group (p = 0.290). In the multiple linear regression with the length of hospital stay outcome and adjusting for potential confounding factors, there was an average reduction of 2.9 days in the hospital stay (p = 0.04) for the early drainage group (< 72 hours) compared to the controls. Early clinical improvement and an expected drop in CRP were more frequent in patients who underwent drainage. Length of hospital stay increases with abscess diameter: 0.4 [(95% CI 0.1 - 0.7) (p = 0.05)] days per centimeter, regardless of other variables., Conclusions: Ultrasound-guided drainage of tubo-ovarian abscesses associated with antibiotic therapy is an effective treatment, with few complications, and may lead to clinical improvement especially when performed early., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2024 Vicente S Antonello, Suelyn Cristina P Ramos, Mirela F Jimenez, Felipe F Bassols.)

Aim: The purpose of the study was to compare the ovarian reserve after cystectomy of ovarian endometrioma by bipolar coagulation, suture method, or hemostatic sealants (HSs)., Methods: We performed a meta-analysis of studies in which post-cystectomy serum anti-Müllerian hormone (AMH) values were compared between bipolar coagulation and suture method or between bipolar coagulation and HSs. Through a literature search, we retrieved 14 articles which met inclusion criteria and were eligible for final analysis. The articles included 10 randomized trials, 3 prospective studies, and 1 retrospective study (n = 1435). The primary outcome was post-cystectomy serum AMH values., Results: Both bipolar coagulation and suture methods showed significantly lower post-cystectomy AMH values at 3, 6, and 12 months. However, post-cystectomy serum AMH values at 12 months were significantly higher in the suture method group compared to the bipolar coagulation (weighted mean difference [WMD]: -1.10, 95% confidence interval [CI]: -1.83, -0.38, p = 0.003, I 2  = 89, n = 3). The suture method also showed a lower decline rate at 3 months post-cystectomy compared to the bipolar coagulation group (WMD: -25.13%, 95% CI: -49.56 to -0.70, p = 0.04, I 2  = 95%, n = 2). Overall, pregnancy rates were similar between the two groups. Between the bipolar coagulation and HSs group, serum AMH values at 3 months post-cystectomy were similar (WMD: -0.46, 95% CI: -1.04 to 0.13, p = 0.13, I 2  = 0%, n = 3). However, the HSs group showed a less decline rate at 3 months post-cystectomy compared to the bipolar coagulation group (WMD: -17.02%, 95% CI: -22.81, -11.23, p < 0.00001, I 2  = 0%, n = 3)., Conclusions: Both the suture method and HSs may have potential benefits in the preservation of ovarian reserve over the bipolar coagulation method when cystectomy for ovarian endometrioma is performed., (© 2024 Japan Society of Obstetrics and Gynecology.)

Ovarian endometriomas affect many patients with endometriosis and have significant effects on quality of life, fertility, and risk of malignancy. Endometriomas range from small (1-3 cm), densely fibrotic cysts to large (20 cm or greater) cysts with varying degrees of fibrosis. Endometriomas are hypothesized to form from endometriotic invasion or metaplasia of functional cysts or alternatively from ovarian surface endometriosis that bleeds into the ovarian cortex. Different mechanisms of endometrioma formation may help explain the phenotypic variability observed among endometriomas. Laparoscopic surgery is the preferred first-line modality of diagnosis and treatment of endometriomas. Ovarian cystectomy is preferred over cyst ablation or sclerotherapy for enabling pathologic diagnosis, improving symptoms, preventing recurrence, and optimizing fertility outcomes. Cystectomy for small, densely adherent endometriomas is made challenging by dense fibrosis of the cyst capsule obliterating the plane with normal ovarian cortex, whereas cystectomy for large endometriomas can carry unique challenges as a result of adhesions between the cyst and pelvic structures. Preoperative and postoperative hormonal suppression can improve operative outcomes and decrease the risk of endometrioma recurrence. Whether the optimal management, fertility consequences, and malignant potential of endometriomas vary on the basis of size and phenotype remains to be fully explored., Competing Interests: Financial Disclosure Ann M.

Currently, three crucial questions regarding the reliability of ovarian reserve measures in women with ovarian endometrioma during the reproductive age are being discussed. Firstly, the effects of endometriotic cystectomy on short and long-term ovarian reserve. Secondly, the accuracy of serum anti-Müllerian hormone (AMH) and antral follicle count (AFC) in estimating ovarian reserve in these cases. Thirdly, the impact of endometrioma itself on the ovarian reserve over time in such cases. The purpose of the present review is to critically assess available systematic reviews and meta-analyses that have explored these questions. Nine eligible reviews were found following a systematic search on PubMed.com and similarly assessed. These reviews varied considerably regarding the level of evidence, as per an identical comprehensive scoring system. Moderate to high-quality evidence demonstrates that endometriotic cystectomy, by the stripping technique, adversely affects ovarian reserve in the short and long term, up to 9-18 months post-surgery. Damage to ovarian reserve was considerable but more pronounced in bilateral cases than unilateral cases, equivalent to 39.5% and 57.0%, respectively. Repeat endometriotic cystectomy is detrimental to ovarian reserve. The impact of endometrioma diameter on ovarian reserve before or after surgery is still unclear. Moderate to high-quality evidence, relying on simultaneous assessment of both ovarian reserve measures, shows that AMH is sensitive while AFC is not in cases undergoing ovarian cystectomy. AMH should be the biomarker of choice for counseling and managing women with endometrioma in their reproductive age, especially before surgery. While there is some evidence to show that endometrioma per se may harm ovarian reserve, this evidence is not robust, and there is good-quality evidence to challenge this notion. It is necessary to conduct further targeted RCTs, systematic reviews, and meta-analyses based on solid methodological grounds to increase the level of evidence, refine quantitative estimates, investigate open questions, and decrease heterogeneity., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Objective: To evaluate the effect of hormonal suppression of endometriosis on the size of endometriotic ovarian cysts., Data Sources: The authors searched MEDLINE, PubMed, Cochrane Central Register of Controlled Trials, Embase, and ClinicalTrials.gov from January 2012 to December 2022., Methods of Study Selection: We included studies of premenopausal women undergoing hormonal treatment of endometriosis for ≥3 months. The authors excluded studies involving surgical intervention in the follow-up period and those using hormones to prevent endometrioma recurrence after endometriosis surgery. Risk of bias was assessed with the Newcastle-Ottawa Scale and Cochrane Risk of Bias Tool. The protocol was registered in PROSPERO (CRD42022385612)., Tabulation, Integration, and Results: The primary outcome was the mean change in endometrioma volume, expressed as a percentage, from baseline to at least 6 months. Secondary outcomes were the change in volume at 3 months and analyses by class of hormonal therapy. The authors included 16 studies (15 cohort studies, 1 randomized controlled trial) of 888 patients treated with dienogest (7 studies), other progestins (4), combined hormonal contraceptives (2), and other suppressive therapy (3). Globally, the decrease in endometrioma volume became statistically significant at 6 months with a mean reduction of 55% (95% confidence interval, -40 to -71; 18 treatment groups; 730 patients; p <.001; I 2 = 96%). The reduction was the greatest with dienogest and norethindrone acetate plus letrozole, followed by relugolix and leuprolide acetate. The volume reduction was not statistically significant with combined hormonal contraceptives or other progestins. There was high heterogeneity, and studies were at risk of selection bias., Conclusion: Hormonal suppression can substantially reduce endometrioma size, but there is uncertainty in the exact reduction patients may experience., (Copyright © 2024 AAGL.

Objective: To highlight a novel surgical approach for the management of undescended ovaries in those presenting with infertility, to allow for potential transvaginal egg retrieval. The video demonstrates a novel surgical approach for mobilization and oophoropexy of undescended ovaries to allow for future transvaginal egg retrieval in the context of artificial reproductive technology (ART)., Design: Case report. Institutional Review Board approval is not required because this was not a human study. Patient consent was obtained for video footage., Setting: Hospital., Patients: We present a 26-year-old nulligravid woman with a unicornuate uterus, a high riding-right ovary, and an undescended left ovary with prior laparoscopic remnant uterine horn resection. Because of her 9 years of infertility and a prior unsuccessful ovarian mobilization and oophoropexy, she was referred for consideration of a repeat laparoscopic bilateral ovarian mobilization and oophoropexy., Intervention: Surgical intervention for undescended ovaries., Main Outcome Measures: Postoperative ovarian location and postoperative pain., Results: The patient reported minimal pain postoperatively at 6 weeks. Multiple follow-up imaging revealed both ovaries behind the uterus (antral follicle counts 15), with easy transvaginal access for future ART., Conclusion: Undescended ovary is uncommon and usually requires no treatment. However, intervention may be required in the context of infertility and ART, where transvaginal egg retrieval is impossible because of the location of the ovaries. This is the first educational video to our knowledge highlighting a novel surgical approach for the management of undescended ovaries., Competing Interests: Declaration of interests Y.T. has nothing to disclose.

Endometriomas may contribute to infertility and are associated with diminished ovarian reserve. Surgical management can damage the ovarian cortex and further diminish ovarian reserve. Surgical therapy of endometriomas can be achieved via cystectomy, ablation (electrosurgical, laser, or plasma energy), sclerotherapy, or oophorectomy. Each approach has varying effects on ovarian reserve, spontaneous pregnancy rates, and recurrence rates: Cystectomy is associated with a low recurrence rate but higher risk of diminished ovarian reserve; Ablation (with laser or plasma energy) appears to have minimal effect on ovarian reserve while also having low recurrence rates; Sclerotherapy is mixed in terms of effect on ovarian reserve as well as recurrence rates. Fertility preservation counseling is recommended for patients considering surgical management. The surgical approach selected should be tailored to each individual patient with respect to their fertility and therapeutic goals., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to disclose., (Copyright © 2023 Elsevier Ltd.

Objectives: Tubo-ovarian abscess (TOA) is inflammation of the pelvic organs, mainly originating from the lower genital tract and intestinal tract. Treatment options include antibiotic therapy, surgical drainage, and radiologically guided (interventional) drainage. In our study, we aimed to evaluate the treatment method to be chosen and thus to manage patients with tuba ovarian abscesses (TOAs) most accurately., Material and Methods: This is a retrospective cohort study, and patients who applied to a tertiary center diagnosed with tuba ovarian abscess (TOA) were included. TOA size (cm), pre-treatment C-reactive protein (CRP) value, pre-treatment white blood cell (WBC) value, previous operation type, postoperative complication, and antibiotics used were screened., Results: 305 patients were included in the study, and medical treatment was applied to 140 patients, organ-sparing surgical drainage to 50 patients, and surgical treatment to 115 patients. TOA dimensions measured at the time of diagnosis were significantly lower in patients for whom only medical treatment was sufficient. Pre-treatment CRP levels, WBC levels, and length of stay were significantly lower in patients for whom only medical treatment was sufficient. There was no significant difference between the pre-and post-procedure CRP difference, antibiotics, and hospitalization time., Conclusions: Preferring minimally invasive treatment in cases requiring invasive treatment reduces the frequency of complications. Treatment of tuba ovarian abscesses (TOA) with minimally invasive methods will be more beneficial in terms of patient morbidity.

Background: Almost 10% of women in reproductive age are diagnosed with ovarian endometriomas and can experience symptoms and infertility disorders. Ovarian endometriomas can be treated with medical or surgical therapy., Objective: To assess whether long-term therapy with dienogest or oral cyclic estrogen-progestogens is effective in reducing the size of ovarian endometriomas, alleviating associated symptoms, and reducing the requirement for surgery., Design: Prospective non-interventional cohort study., Methods: We enrolled childbearing women diagnosed with ovarian endometriomas. We collected demographic, clinical, and surgical data, including the evaluation of ovarian endometrioma-associated symptoms and pain using the visual analog scale. We grouped the women according to treatment regimen into dienogest, estrogen-progestogens, and no-treatment. Patient's assessment was performed at baseline and after 12 months evaluating the largest ovarian endometrioma diameter (in millimeters) and the associated symptoms. Furthermore, we analyzed the impact of hormonal treatment in a sub-group of women fulfilling at baseline the criteria for a first-line surgical approach (ovarian endometrioma > 30 mm with visual analog scale > 8 or ovarian endometrioma > 40 mm before assisted reproductive treatments or any ovarian endometrioma(s) > 60 mm)., Results: We enrolled 142 patients: 62, 38, and 42 in dienogest, estrogen-progestogens, and no-treatment groups, respectively. No significant differences were found regarding baseline characteristics. After 12 months, the mean largest ovarian endometrioma diameter increased in the no-treatment group (31.1 versus 33.8; p < 0.01), while a significant reduction was registered in the dienogest (35.1 versus 25.8; p < 0.01) and estrogen-progestogens (28.4 versus 16.7; p < 0.01) groups; no significant difference in ovarian endometrioma diameter reduction between these two latter groups was noted (p = 0.18). Ovarian endometrioma-associated symptoms and pain improved in dienogest and estrogen-progestogens groups, with a significantly greater effect for dienogest than for estrogen-progestogens for dysmenorrhea (74% versus 59%; p < 0.01). In the sub-group of women eligible for first-line surgery at baseline, long-term treatment with dienogest and estrogen-progestogens reduced surgical eligibility by 30%., Conclusions: Decreased mean largest ovarian endometriomas'diameter after 12 months and reduction of the need for surgical treatment by 30% were observed in dienogest and estrogen-progestogens groups. Long-term treatment with dienogest had a greater effect in alleviating dysmenorrhea and pain.

Background: Ovarian torsion in infants can be asymptomatic or may present with abdominal mass and malnutrition. It is an uncommon and non-specific condition in children. We report a girl who underwent detorsion and ovariopexy for suspected ovarian torsion after a previous oophorectomy. The role of progesterone therapy is determined in reducing the size of adnexal mass., Case Presentation: The patient was diagnosed with right ovarian torsion and underwent an oophorectomy at one year of age. About 18 months later, she was diagnosed with left ovarian torsion and underwent detorsion with lateral pelvic fixation. Despite the pelvic fixation of the ovary, a continuous increase in the volume of the ovarian tissue was evident during successive ultrasounds. Progesterone therapy was started at five years of age in order to prevent retorsion and preserve the ovarian tissue. In successive follow-ups during the therapy, ovarian volume decreased, and its size (27*18 mm) was restored., Conclusion: The presented case reminds doctors of the possibility of ovarian torsion in young girls with pelvic pain. More research is needed on the use of hormonal drugs, such as progesterone, in similar cases., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

A Comparison of Ovarian Loss Following Laparoscopic versus Robotic Cystectomy As Analyzed by Artificial Intelligence-Powered Pathology Software., Background and Objective: To compare the area of ovarian tissue and follicular loss in the excised cystectomy specimen of endometrioma performed by laparoscopic or robotic technique., Methods: Prospective observational study performed between April 2023 to August 2023. There were 14 patients each in Laparoscopic group (LC) and Robotic group (RC). Excised cyst wall sent was for to the pathologist who was blinded to the technique used for cystectomy. The pathological assessment was done by artificial intelligence-Whole Slide Imaging (WSI) software., Results: The age was significantly lower in LC group; the rest of demographic results were comparable. The mean of the median ovarian area loss [Mean Rank, LC group (9.1 ± 15.1); RC (8.1 ± 12.4)] was higher in LC group. The mean of the median total follicular loss was higher in LC group (8.9 ± 9.2) when compared to RC group (6.3 ± 8.9) and was not significant. The area of ovarian loss in bilateral endometrioma was significantly higher in LC group (mean rank 7.5) as compared to RC group (mean rank 3) - ( P  = .016) despite more cases of bilateral disease in RC group. With increasing cyst size the LC group showed increased median loss of follicles when compared to RC group (strong correlation coefficient 0.347) but not statistically significant ( P  = .225). AAGL (American Association of Gynecologic Laparoscopists) score did not have any impact on the two techniques., Conclusion: Robotic assistance reduces the area of ovarian and follicular loss during cystectomy of endometrioma especially in bilateral disease and increasing cyst size. It should be considered over the laparoscopic approach if available., (© 2024 by SLS, Society of Laparoscopic & Robotic Surgeons.)

Objectives: To assess the characteristics of patients with unilateral and bilateral tubo-ovarian abscess (TOA)., Methods: Women diagnosed with TOA during 2003-2017 were included in this retrospective cohort study. TOA was diagnosed using sonography or computerized tomography and clinical criteria, or by surgical diagnosis. Demographics, sonographic data, clinical treatment, surgical treatment, and post-operative information were retrieved., Results: The study cohort included 144 women who met the inclusion criteria, of whom 78 (54.2%) had unilateral TOA and 66 (45.8%) had bilateral TOA. Baseline characteristics were not different between the groups. There was a statistical trend that women with fewer events of previous PID were less likely to have with bilateral TOA (75.3% vs. 64.1%, respectively; p = 0.074). Women diagnosed with bilateral TOA were more likely to undergo surgical treratment for bilateral salpingo-oophorectomy compared to unilateral TOA (61.5% vs. 42.3%, respectively; p = 0.04). There was no difference in maximum TOA size between groups., Conclusions: This study detected a trend toward increased need for surgical treatment in women diagnosed with bilateral TOA. These findings may contribute to determining the optimal medical or surgical treatment, potentially leading to a decrease in the duration of hospitalization, antibiotic exposure, and resistance. However, it is important to acknowledge that the results of the current study are limited, and further research is warranted to validate these potential outcomes., (© 2023. The Author(s).)

Study Objective: Recurrent torsion of otherwise normal adnexa (not involving adnexal cysts) has been reported in young girls and adolescents. Previous ovarian fixation techniques (oophoropexy), such as plication of the utero-ovarian ligament, appear to have limited efficacy in preventing recurrent torsion. A novel technique combining plication of the utero-ovarian ligament and suturing of the ovary to the round ligament has recently been described. In this study, we describe our short-term experience with the combined utero-ovarian and round ligament oophoropexy technique., Methods: Patients who underwent combined oophoropexy as a primary fixation technique or as a secondary fixation technique (ie, after failure of a previous fixation) due to recurrent torsion of otherwise normal adnexa between January 2020 and December 2022 were included in this retrospective cohort study. Follow-up to assess for further torsion events was conducted by telephone interview., Results: Ten patients underwent combined utero-ovarian and round ligament oophoropexy during the study period. In all cases, at least 2 episodes of torsion of otherwise normal adnexa were surgically diagnosed before oophoropexy (range 2-4). The median patient age at the time of combined oophoropexy was 21.8 years (range 9.1-35.7 years); 3 were premenarchal, and 7 were postmenarchal. After a median follow-up of 19.1 months (range 3.0-29.3 months), only 1 case of recurrent torsion occurred., Conclusion: Combined utero-ovarian and round ligament oophoropexy is novel oophoropexy procedure that may reduce the risk of recurrent torsion. However, longer follow-up is needed to determine its efficacy., Competing Interests: Conflicts of Interest None., (Copyright © 2023. Published by Elsevier Inc.)

Purpose: We aimed to compare the results of image-guided drainage in addition to antibiotic therapy (antibiotherapy) with antibiotherapy alone in the treatment of tubo-ovarian abscesses (TOAs) and evaluate C-reactive protein (CRP) levels in predicting the success of antibiotherapy., Methods: This was a retrospective study of 194 patients hospitalized with TOA. Patients were divided into the following two groups: those who underwent image-guided drainage in addition to parenteral antibiotherapy and those who did not undergo image-guided drainage and received antibiotherapy alone. CRP levels on the day of admission (day 0), day 4 of hospitalization (day 4), and day of discharge (last day) were recorded. The percentage of decrease in CRP levels during day 4 and the last day compared with that on day 0 was calculated., Results: A total of 106 patients (54.6%) underwent image-guided drainage with antibiotherapy, whereas 88 patients (45.4%) did not undergo drainage and received antibiotherapy alone. At admission, the mean CRP level was 203.4 (± 96.7) mg/L and was similar in both groups. The mean decrease in the CRP level on day 4 compared with that on day 0 was 48.5% and was statistically higher in the group that underwent image-guided drainage. Antibiotherapy failed in 18 patients, and a statistically significant difference was observed between treatment failure and the rate of decrease in the CRP level on day 4 compared with that on day 0. According to the receiver operating characteristic (ROC) analysis, if the CRP level measured on day 4 decreased by < 37.1% compared with that on day 0, the probability of treatment failure would increase (area under the curve = 0.755; 95% confidence interval, 0.668-0.841; sensitivity, 73.6%; specificity, 60%)., Conclusions: Image-guided drainage combined with antibiotherapy in the treatment of TOA has high success rates, lower recurrence rates, and lower surgical requirement, and the mean decrease in the CRP level on day 4 can be monitored at treatment follow-up. In patients receiving antibiotherapy alone, if the CRP level on day 4 decreases by < 37.1%, the treatment protocol should be changed., (© 2023.

Study Objective: To identify preoperative transabdominal sonographic predictors of surgically confirmed ovarian torsion (OT) in premenarchal girls METHODS: We conducted a retrospective case-control study of 32 premenarchal girls aged 0-12 undergoing surgery for OT (cases) or a non-torsed ovarian mass (controls) from 2006 to 2017 at a single academic center. Cases had ICD-9/10 codes for torsion of the ovary, adnexa, ovarian pedicle, or fallopian tube and surgically confirmed OT; controls had codes for ovarian mass or cyst and surgically confirmed absence of OT. Preoperative transabdominal ultrasounds were analyzed by 3 radiologists blinded to final diagnosis. We used χ 2 , Fisher[s exact, and Student's t tests for statistical comparisons., Results: From 2016 to 2017, 32 patients presented with acute abdominal pain or symptoms concerning for ovarian mass requiring ultrasound imaging and subsequent diagnostic laparoscopy; 24 (75.0%) had confirmed OT by laparoscopy, and 8 (25.0%) did not. The mean age in both groups was similar (7.3 ± 2.9 years). Preoperative sonographic variables significantly associated with OT included presence of a simple cyst (20.8% vs 12.5%), ovarian heterogeneity (100% vs 12.5%), presence of peripheralized follicles (70.8% vs 0%), and asymmetry of color Doppler (75.0% vs 37.5%; all P < .05). Presence of free fluid, arterial color Doppler, and a whirlpool sign were not predictive of OT., Conclusion: In premenarchal patients, although certain variables on transabdominal sonography predicted surgically confirmed OT, only the presence of peripheralized follicles was unique to girls with OT. The decision to proceed with diagnostic laparoscopy for suspected OT can be aided by these specific sonographic findings but should ultimately be based on high clinical suspicion., (Copyright © 2023.

Study Objective: Ovarian torsion (OT) in pediatric age is a challenging condition to diagnose and treat. To date, there is still no clear consensus about its management. Our aim was to assess some possible associated factors that can help surgeons in decision-making., Design: We conducted a retrospective multicentric study of pediatric OT surgically treated between 2010 and 2020 in six Italian and German institutions, comparing our findings with a literature review of the last 10 years (2010-2020)., Participants: Patients aged 0-18 years with a diagnosis of OT intraoperatively confirmed and surgically treated at the involved institutions., Results: Ninety-seven patients with a mean age at diagnosis of 8.37 years were enrolled in the study. Severe abdominal pain was present in 82 patients (84.5%). Eighty children (82.5%) presented an enlarged ovary with an US diameter > 5 cm and only 32 (40%) of them underwent conservative surgery. A laparoscopic approach was performed in 60 cases (61.9%) although in 15 (15.5%) conversion to open surgery was deemed necessary. A functional cyst was present in 49 patients (50.5%) while 11 children (11.3%) suffered from OT on a normal ovary., Conclusions: Our results showed that a post-menarchal age (p = .001), a pre-operative US ovarian size < 5 cm, (p = .001), the presence of severe abdominal pain (p = .002), a laparoscopic approach (p < .001), and the presence of a functional cyst (p = .002) were significantly associated with conservative surgery., (© 2022.

Study Objective: To demonstrate the feasibility of management of large endometrioma laparoscopically., Design: Stepwise demonstration with narrated video footage of the laparoscopic 2-step procedure starting with alcohol sclerotherapy of the large endometrioma followed by CO 2 laser ablation and 6-month follow-up., Setting: The debate surrounding the best approach for the management of large endometriomas has been ongoing. Cystectomy especially when treating large endometriomas has been shown to decrease ovarian reserve proportionally to the endometrioma's size. 2 , 4 This is why 2-step approaches have been considered to preserve the ovarian reserve. 1 , 3 We present the case of a 22-year-old nulliparous woman who has primary severe dysmenorrhea resistant to medical treatment. Magnetic resonance imaging shows uterine adenomyosis and a 10 cm large endometrioma of the left ovary and no signs of deep infiltrative endometriosis. She has a desire for pregnancy in the distant future., Intervention: The first step is the laparoscopic ethanol sclerotherapy. After emptying and rinsing the endometrioma's cavity through a 5 mm suction cannula, it is then filled with ethanol through a 14 French Foley catheter to avoid any overflow. 5 , 6 After a time exposure of 10 minutes, the ethanol is withdrawn and the cavity rinsed (Figure 2). The second step of the surgery is performed 12 weeks later (Figure 3). Using CO 2 laser, the untreated portion of the inner wall of the remaining endometrioma is vaporized along with remaining superficial endometriosis lesions (Figure 1)., Conclusion: Laparoscopy sclerotherapy combined to CO 2 laser ablation is a feasible technique for the management of a large endometrioma. Further research is still required to evaluate the benefit of a 2-step surgery approach over standard cystectomy and to understand the long-term effects of ethanol-induced ovarian fibrosis., (Copyright © 2022 AAGL.

Purpose: To evaluate the clinical outcomes and prognosis of patients undergoing laparoscopic surgery for tubo-ovarian abscess (TOA) and identify risk factors for pelvic inflammatory disease (PID) recurrence., Methods: We conducted a retrospective cohort analysis including 98 women who underwent laparoscopic surgery for TOA at the Department of Obstetrics and Gynecology at the Bern University Hospital from January 2011 to May 2021. The primary outcome studied was the recurrence of PID after TOA surgery. Clinical, laboratory, imaging, and surgical outcomes were examined as possible risk factors for PID recurrence., Results: Out of the 98 patients included in the study, 21 (21.4%) presented at least one PID recurrence after surgery. In the univariate regression analysis, the presence of endometriosis, ovarian endometrioma, and the isolation of E. coli in the microbiology cultures correlated with PID recurrence. However, only endometriosis was identified as an independent risk factor in the multivariate analysis (OR (95% CI): 9.62 (1.931, 47.924), p < 0.01). With regard to the time of recurrence after surgery, two distinct recurrence clusters were observed. All patients with early recurrence (≤ 45 days after TOA surgery) were cured after 1 or 2 additional interventions, whereas 40% of the patients with late recurrence (> 45 days after TOA surgery) required 3 or more additional interventions until cured., Conclusion: Endometriosis is a significant risk factor for PID recurrence after TOA surgery. Optimized therapeutic strategies such as closer postsurgical follow-up as well as longer antibiotic and hormonal therapy should be assessed in further studies in this specific patient population., (© 2022.

Objectives: To compare success rates and complications in women undergoing laparoscopic versus open surgical management of tubo-ovarian abscess. We further examined whether early laparoscopic intervention has any impact on pregnancy rates in a subgroup of infertile patients following frozen-thawed embryo transfer., Material and Methods: Hospital records of 48 patients diagnosed with TOA between January 2015 and December 2020, who underwent surgical intervention or received only medical treatment were analyzed. All patients were hospitalized, and parenteral antibiotics were commenced on admission initially. Laparoscopic or open surgery was performed within 48 hours course of intravenous antibiotherapy (early intervention) or later according to the clinical findings and antibiotherapy response., Results: Of 48 patients with TOA, 18 (37.5%) underwent laparoscopic and 30 (62.5%) underwent open surgical intervention. The median postoperative hospital stay was shorter (4.5 days vs 7.5 days, respectively; p = 0.035), and postoperative opioid analgesic requirement was lesser in the laparoscopy group compared to open surgery group (22% vs 53%, respectively; p = 0.034). Intra- and post-operative complication rates were similar between the groups. Of these 48 patients, seven were diagnosed to have TOA following oocyte retrieval, and four of these conceived with frozen thawed embryo transfer all of whom underwent laparoscopic surgery within 48 hours of diagnosis., Conclusions: Minimal invasive surgery should be preferred even in the presence of severely adhesive and inflammatory TOA in order to improve postoperative outcomes. Moreover, early laparoscopic intervention may be considered in infertile patients with an aim to optimize pregnancy rates in a subsequent frozen-thawed embryo transfer.

This study aimed to investigate the protective effect of ozone therapy on ovarian reserve, number of ovarian follicles, ovarian morphology in a rat ischaemia reperfusion (IR) injury model. Twenty-four, Wistar Hannover rats were included. The rats were divided into three groups as control, detorsion-only, and ozone therapy + detorsion groups. There was a statistically significant difference in the follicular damage and inflammation scores between the study groups ( p  = .019, p  = .002, respectively). The highest AMH decrease was observed in the detorsion-only group ( p  = .012). The total damage score was higher in the detorsion-only group than the ozone therapy + detorsion group. Preantral, small and large antral follicle numbers were less in the detorsion-only group than the ozone therapy + detorsion group. The highest postoperative day 7 TAS level was in the ozone therapy + detorsion group. TOS levels did not differ significantly between the study groups. The combination of the ozone therapy with ovarian detorsion is more effective in protecting the ovarian reserve than ovarian detorsion-only.Impact Statement What is already known on this subject? Adnexal torsion is a common gynecological emergency in reproductive-age women. The recommended management is the detorsion of the adnexal pedicle in patients with fertility desire. What do the results of this study add? The combination of the medical ozone therapy with conventional surgical ovarian detorsion is more effective in the protection of the ovarian reserve compared to surgical ovarian detorsion. What are the implications of these findings for clinical practice and/or further research? This study speculates that medical ozone therapy in addition to conventional surgical ovarian detorsion could preserve ovarian reserve and function if confirmed in further clinical studies.

Background: Management of ovarian torsion ranges from de-torsion to oophorectomy and is dependent on various factors. Oophorectomy can have significant implications for fertility and general health, thus requiring careful consideration., Aims: We evaluate the management of ovarian torsion at a tertiary hospital over a ten-year period and identify the predictors of oophorectomy in ovarian torsion cases., Materials and Methods: Inpatient notes of patients who underwent surgical management for acute ovarian torsion at a tertiary hospital in Victoria, Australia, were reviewed, from January 2008 to June 2018. We reported the incidence and predictors of oophorectomy and ovarian ischaemia and current practices in oophoropexy., Results: Our analysis included 159 patients. The incidence of oophorectomy was 47%. After confounders were adjusted, increasing age was the only significant predictor for oophorectomy. The adjusted odds ratio of having an oophorectomy based on age alone was 1.10 for each year increase in age between the ages of 15 and 68 (P = 0.001, 95% confidence interval 1.04-1.16). Of those with oophorectomy, 57% had ischaemia confirmed histologically. There were no significant predictors for ischaemia., Conclusion: The incidence of oophorectomy in this audit is comparable to reported incidences in current literature. However, with increasing evidence to support ongoing ovarian function even in cases where ischaemia is histologically confirmed, this incidence could be lowered. Age was the only variable that was found to have a significant effect on the incidence of oophorectomy., (© 2022 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)

Study Objective: To identify risk factors for recurrent ovarian torsion and evaluation of the efficacy of oophoropexy techniques., Design: Case control study., Setting: Tertiary university-affiliated medical center., Patients: A total of 79 women with recurrent ovarian torsion (study group) were matched with 158 women with a single episode of ovarian torsion (control group)., Interventions: Laparoscopic detorsion and oophoropexy., Measurements and Main Results: Demographic data, clinical characteristics, ultrasound characteristics, surgical findings, surgical procedures, and torsion recurrence rates were analyzed and compared between the 2 groups between 2001 to 2020., Results: There was an inverse association between women's age and the risk of recurrent torsion (adjusted odds ratio [aOR], 0.89; 95% confidence interval [CI], 0.83-0.96, p = .003). Moreover, in women younger than 20 years, the risk of recurrent event was substantially higher (aOR, 5.0; 95% CI, 1.56-6.15, p = .007). In addition, the absence of ovarian pathology was associated with increased risk for recurrent torsion (aOR, 14.3; 95% CI, 6.15-33.42; p <.001). Oophoropexy was performed in 46 women in the study group. The risk of recurrent torsion after oophoropexy was 30%. A long duration of pain before admission was associated with oophoropexy failure (37.5 ± 6.3 hours vs 11.7 ± 6.0 hours, p = .003). No single fixation procedure was superior to the others in terms of therapeutic success., Conclusion: Recurrent ovarian torsion is more common in young women with a normal-appearing ovary. Oophoropexy is a safe procedure with a risk of retorsion in 30% of the patients. We found no advantage for one fixation technique over the others., (Copyright © 2022 AAGL. Published by Elsevier Inc.

Purpose of Review: Adnexal torsion remains a diagnostic challenge heavily reliant on high clinical suspicion, with patient presentation and imaging used as adjuncts to aid in its diagnosis. This review summarizes diagnostic and management techniques of adnexal torsion to assist providers when encountering this surgical emergency., Recent Findings: Common findings of adnexal torsion include abdominal pain, nausea, vomiting, and adnexal mass or ovarian enlargement. An elevated neutrophil to lymphocyte ratio may be useful for diagnosis. A 'whirlpool' sign, 'follicular ring' sign, enlarged/edematous ovary, and absent Doppler flow to the ovary are highly suggestive of adnexal torsion. Intraoperative visual diagnosis of ovarian death is highly inaccurate, with only 18-20% of ovaries necrotic on pathological examination. Necrotic appearing ovaries have been shown to have follicular activity on ultrasound one year postoperatively., Summary: Pelvic ultrasound remains the first-line imaging modality. In patients of reproductive age, we recommend performing detorsion with ovarian conservation, even in cases where the tissue appears necrotic, given poor intraoperative diagnostic rates of tissue death. Retention of ovarian function is also reliant on a timely diagnosis and intervention. We emphasize that the risk of ovarian damage/loss outweigh the risk of a diagnostic laparoscopy in patients of reproductive age., (Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.)

Background The application of carbon dioxide (CO 2 ) laser for laparoscopic gynecologic surgery was introduced in 1979 and spread after improving instrumentation, due to the versatility of the CO 2 laser technology and the parallel increase of laparoscopic use. In a gynecologic setting, laser laparoscopy has been demonstrated to be effective in treating infertility and pain associated with mild to severe endometriosis.Aim and methods: This document aims at conducting a systematic review to provide a comprehensive literature overview regarding the rationale, indications, safety, and efficacy of CO 2 laser treatment of endometriosis and related outcomes on ovarian reserve and fertility. Results CO 2 laser seems to lead to lower heat damage in the ovarian tissue than bipolar energy during endometriomas treatment. Moreover, several reports have pointed out that laser vaporization allows to selectively destroy the endometrioma wall's internal surface, preserving the pericystic fibrotic capsule or the adjacent healthy ovarian cortex. Despite this, robust data we have so far indicates that the most effective laparoscopic approach for managing endometriomas is the traditional excisional technique providing better postoperative outcomes than drainage and electrocoagulation, and laser treatment. Data about fertility after treatment of deep infiltrating endometriosis (DIE) using dioxide laser are emerging but very poor. Conclusions Current scientific evidence in this field is inconclusive, and the debate about the safety and efficacy of the CO 2 laser on fertility outcomes is still ongoing. Further randomized case-control studies are mandatory to attain more consistent evidence.

Background: Ovarian clear cell carcinoma (OCCC) is the most common endometriosis-associated ovarian cancer. Ovarian endometriosis may present with atypical or malignant sonographic features and interfere with clinical judgment about whether definitive surgical intervention is required., Objective: To compare the characteristics of endometrioma with atypical features and OCCC., Methods: This study enrolled patients with pathologic diagnoses of either endometrioma or OCCC. For patients with endometrioma, only those with atypical features, defined as the presence of at least one of the following sonographic characteristics: cyst diameter of 10 ± 1 cm, multi-cystic lesions, any solid component or papillary structure, and blood flow of any degree, were included., Results: Sixty-three patients had endometriomas with atypical features, while 57 patients had OCCC. Patients with endometriomas were younger (39.33 ± 7.04 years vs. 53.11 ± 9.28 years, P < 0.01), had smaller cysts (7.81 ± 2.81 cm vs. 12.68 ± 4.60 cm, P < 0.01), and had smaller solid components (0.93 ± 1.74 cm vs. 4.82 ± 3.53 cm, P < 0.01). In contrast, OCCCs were associated with loss of ground-glass echogenicity (6.3% vs 68.4%, P < 0.01). In multivariate analysis, advanced age (> 47.5 years), large cysts (> 11.55 cm), large solid components (size > 1.37 cm), and loss of ground-glass echogenicity were independent factors suggestive of malignancy., Conclusion: Advanced age, larger cyst sizes, larger solid component sizes, and loss of ground-glass echogenicity are major factors differentiating endometriomas from malignancies. For women in menopausal transition who have finished childbearing who present with endometrioma with atypical features, removal of the adnexa intact could be considered., (© 2022. The Author(s).)

This study aimed to compare the effectiveness of NAC plus low dose contraceptive with low dose contraceptives alone. This was a randomised trial on a sample of women who underwent conservative laparoscopic surgery for ovarian endometrioma. Patients were randomly assigned either to the NAC plus low dose contraceptive group ( n  = 48) or low dose contraceptive alone ( n  = 52). To evaluate the recurrence rate transvaginal ultrasound was performed. Pelvic pain was assessed using a visual analogue scale (VAS). All assessments were performed at two points in time: 3 and 6 months post-surgery and compared between the two regimens. The findings indicated that reduction in the recurrence rate of endometrioma and pelvic pain were similar between both groups. The findings showed that adding N-acetylcysteine to low dose contraceptive treatment has a similar effect in reducing the recurrence rate of endometrioma and pelvic pain when compared to low dose contraceptives alone.Impact statement What is already known on this subject? Endometriosis is a frequent benign disease-producing inflammatory response with mild to severe symptoms. Although surgical removal of ectopic lesions is the first-line intervention, the recurrence rate of the disease is high. Thus this study aimed to compare the effectiveness of N-acetylcysteine plus low dose contraceptive with low dose contraceptive alone. What do the results of this study add? The findings showed that adding N-acetylcysteine to low dose contraceptive treatment has a similar effect in reducing the recurrence rate of endometrioma and pelvic pain when compared to low dose contraceptives alone. What are the implications of these findings for clinical practice and/or further research? It is recommended to increase the duration of drug administration in future studies.

Research Question: Is there a difference in recurrence rate of endometrioma(s) after cystectomy versus CO 2 laser vaporization of the cyst wall?, Design: This single-centre retrospective study included 270 patients undergoing laparoscopic surgery for endometriomas between January 2010 and December 2014, stratified according to the surgical technique used. All 270 included patients underwent complete laparoscopic surgery for endometrioma(s): 155 underwent cystectomy, 63 complete CO 2 laser vaporization of the cyst wall and 52 a mixed technique. The primary outcome studied was the difference in recurrence rate between the cystectomy group and the CO 2 laser vaporization group., Results: The mean duration of follow-up was 58 (±34) months. Imaging-based recurrence (any cyst size) was reported in 9.9% of patients (n = 12/121) treated with cystectomy and in 13.3% of patients (n = 6/45) who underwent a vaporization (P = 0.577). The need for reintervention for endometrioma(s) was also similar in both groups, with a rate of 3.2% (n = 5/155) after cystectomy and 4.8% (n = 3/63) after vaporization (P = 0.476). Of 160 women who wanted to conceive immediately after surgery, 73.8% became pregnant (72.6% [77/106] in the cystectomy group and 75.9% [41/54] in the vaporization group [P = 0.310]). Conception occurred mostly by assisted reproductive technology (57.1% [44/77] in the cystectomy group and 70.7% [29/41] in the vaporization group [P = 0.074])., Conclusions: Similar rates of recurrence for endometrioma(s) were observed after cystectomy versus CO 2 laser vaporization. As other studies have suggested that CO 2 laser vaporization may be less harmful to the normal ovarian tissue, it can be considered as a safe alternative for cystectomy in women wishing to preserve their reproductive potential., (Copyright © 2022.

Study Objective: Our objective was to determine if ovarian surgery at the time of ovarian detorsion is associated with impaired short-term ovarian function as indicated by ovarian morphology on ultrasound when compared with detorsion alone., Design: Retrospective cohort study SETTING: The Hospital for Sick Children, Toronto PARTICIPANTS: Patients ≤ 18 years old with confirmed ovarian torsion from January 1, 2004, to December 31, 2018, with ovarian-sparing surgery., Main Outcome Measures: Data were collected on demographics, procedure, intraoperative findings, and postoperative ultrasound. To determine ovarian function, we compared the morphology on the postoperative ultrasound between those with surgery to the ovary and those without surgery to the ovary at the time of detorsion. We also compared the ovarian volume of affected and contralateral ovaries after detorsion and surgery to the affected ovary., Results: One hundred and nineteen patients met the inclusion criteria, of whom 67 (56%) had detorsion with surgery to the ovary and 52 (44%) had detorsion alone. There was no statistically significant difference in appearance on the postoperative ultrasound between these groups (P =.446). There was also no statistically significant difference on the postoperative ultrasound of affected and contralateral ovarian volumes after detorsion and surgery to the affected ovary (P = .69). Patients who underwent surgery to the ovary experienced a lower rate of recurrence; however, this did not reach statistical significance, with a P value of 0.080., Conclusion: Our study demonstrates that surgery, eg cystectomy to the ovary at the time of ovarian detorsion, does not appear to impact ovarian function when compared with detorsion alone, as indicated on postoperative imaging. There was also no difference in volume of the affected and contralateral ovaries in those cases that underwent surgery at the time of initial detorsion. This evidence would support that immediate cystectomy at the time of initial ovarian detorsion is not associated with impaired ovarian function, thus avoiding the need for an interval cystectomy., Competing Interests: Disclosure/Conflict of Interest Statement The authors have nothing to declare., (Copyright © 2021.

Rationale: Primary ovarian abscess which develops as an isolated lesion without simultaneous tubal infection is a rare entity. Ovarian abscess (OA) is a serious complication of pelvic inflammatory disease (PID) rarely seen in virginal girls. Early diagnosis and treatment are essential to prevent further sequela including infertility, ectopic pregnancy, and chronic pelvic pain., Patient Concerns: A 19-year-old virginal girl who presented with abdominal pain and pelvic mass with no risk factors., Diagnoses: Laparoscopic surgery was performed to confirm a primary ovarian abscess in the adolescent virginal female with a huge endometriosis cyst., Intervention: Ovarian abscess with extensive intestinal adhesions was determined during the laparoscopic operation. Abscess drainage and postoperative antibiotic therapy cured the patient., Outcome: After the surgery, the CRP level on the day of discharge was 3.18 mg/d. The histological findings revealed a cystic tissue sample with the fibrous wall infiltrated by neutrophilic granulocytes, and ectopic endometrium, suggesting abscess formation in the ovary and endometriosis cyst., Lessons: Although primary ovarian abscess in an adolescent virginal female is rare, given the severity of outcomes following ovarian abscess, this pathology should be considered in the differential diagnosis of virginal adolescents with fever and abdominal pain., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2022 the Author(s).

Study Objective: To assess the external validity of a recently published clinical risk score estimating the risk of failed medical treatment in patients with tubo-ovarian abscess (TOA) based on 4 clinical variables on admission., Design: The probability of failed medical treatment predicted from the reference risk score was compared with the observed rates in a retrospective cohort of patients with TOA. Results were assessed using rigorous methods for clinical prediction models., Setting: Safety-net teaching hospital system in Houston, Texas., Patients: One hundred and sixty nine consecutive patients admitted with TOA between 2011 and 2018 were included. Some were treated conservatively with intravenous antibiotic agents; others required a drainage procedure., Intervention: Electronic health records were reviewed and the 4 clinical predictors of failed conservative treatment were captured (age, white blood cell count on admission, abscess size, and presence of bilateral abscess). A clinical risk score was calculated for each patient. The prediction model was created using the risk score in a multivariate logistic regression. Then the calibration, discrimination, and accuracy of the model were evaluated to perform the external validation analysis., Measurements and Main Results: Among 169 eligible patients, 50.2% were successfully treated with intravenous antibiotic agents and 49.8% needed abscess drainage. Patients undergoing drainage were more likely to be older, be diabetic, to present with elevated white blood cell count and fever, and to have a larger abscess size on univariate analysis. Among the 4 known predictors of drainage, abscess size was found to be the strongest. Significant difference in clinical characteristics was noted between our cohort and the reference cohort, and the model needed recalibration to adjust for these differences. The area under the receiver operating characteristic curve was 0.77 (0.71-0.84) indicating good discrimination. The Brier score was favorable (0.19) and the observed and predicted rates were similar ranging across different risk scores., Conclusions: Our results provide external validation of a simple clinical risk score predicting failed medical treatment in patients with TOA., (Copyright © 2022 AAGL.

Ovarian torsion is rare in the pediatric population. Delayed diagnosis can significantly impact fertility. The aim of this review is to highlight current knowledge regarding clinical presentation, diagnosis, surgical management, and follow-up in the pediatric population. Whilst the presentation is often very unspecific, most children will present with sudden severe unilateral pelvic pain associated with vomiting. A key diagnostic test is pelvic ultrasonography, which may help demonstrate an asymmetric enlarged ovary with peripherally displaced follicles. In the pediatric population, ovarian torsion may occur in a normal ovary. However, underlying lesions can be found in half of cases. Benign neoplasms (teratomas or cystic lesions) represent the commonest etiology, with the risk of malignancy being less than 2%. Surgical management should be focused on fertility preservation. This is achievable through ovarian detorsion ± ovarian cystectomy ± oophoropexy to avoid recurrence. Follow-up studies demonstrate excellent recovery rates of detorsed ovaries including those with ischemic appearances. What is Known: • Ovarian torsion is a rare diagnosis in the pediatric population. • Aspecific symptoms and differential diagnoses lead to missed or delayed diagnosis increasing the risk of oophoprectomy and further infertility. What is New: • Reviewing the latest knowledge about clinical presentation, diagnostic, surgical management, and follow-up of ovarian torsion in the pediatric population. • Adiponectin was negatively associated with diastolic blood pressure and HOMA-IR, and chemerin was negatively associated with glucose., (© 2021.

Study Objective: To quantitatively evaluate the blood flow in ovaries (ischemic ovaries) that underwent torsion using indocyanine green angiography (ICGA) and assess the use of ICGA as an indicator for functional preservation of the ovaries., Design: In vivo animal study., Setting: The University of Yamanashi Animal Experimentation Center., Subjects: Eighteen female Wistar albino rats., Interventions: As an alternative to ovarian torsion, we occluded an ovary in each rat for 24 hours, after which we performed ICGA before and after releasing ischemia and extracted the following 8 parameters: F max (maximum F value before releasing ischemia); T max (time taken from the onset of an increase in F to reaching F max ); T ½max (time taken from the onset of an increase in F to reaching half of F max ); slope (F max /T max ); time ratio (T ½max /T max ); F' max (maximum F value after releasing ischemia); reperfusion rate (F' max /F max ); and reperfusion gap (F' max - F max ). Four weeks later, we counted the total number of primordial and primary follicles and classified the rats into functional and nonfunctional groups., Measurements and Main Results: On the basis of the total number of primordial and primary follicles, 13 rats had "functional" ovaries on the clamped side, and 5 rats had "nonfunctional" ovaries. The area under the curve values for each parameter were as follows: F max , 0.908; T max , 0.569; T ½max , 0.546; time ratio, 0.746; slope, 0.877; F' max , 0.723; reperfusion rate, 0.938; and reperfusion gap, 0.862., Conclusion: ICGA can be used to quantitatively evaluate ovaries that have been subjected to ischemia, and the magnitude of fluorescence intensity can be an excellent predictor of ovarian necrosis. Quantifying the degree of reperfusion immediately after the release of ischemia can be an equally excellent predictor of necrosis., (Copyright © 2021 AAGL. Published by Elsevier Inc.
