Study Objective: To identify factors that prolong total operative time (TOT) in robotic-assisted laparoscopic myomectomy (RALM).Design: Retrospective cohort study.Setting: Tertiary university hospital.Patients: Women who underwent RALM between April 2009 and May 2019 conducted by a single high-volume gynecologic surgeon.Interventions: Patients' demographic data and intraoperative records were obtained. The association between the perioperative characteristics and TOT was analyzed.Measurements and Main Results: A total of 584 cases met the inclusion criteria, with a mean TOT of 231.6 ± 86.7 min. The mean patient age was 36.3 ± 5.5 years, and the patients had a mean of 4.2 ± 4.0 myomas. The dominant myoma had a mean diameter of 7.6 ± 2.6 cm. The mean total weight of the extracted myomas removed was 202.2 ± 152.6 g. From multiple regression analysis, the following perioperative factors were intimately associated with the TOT: ① body mass index, ② the number of myomas, ③ weight of total myomas, ④ location of dominant myoma, ⑤ type of da Vinci robot system, ⑥ endometrial cavity opening during the operation, ⑦ intraoperative blood loss, and ⑧ patient hospitalization period. The number of myoma was most closely related to the TOT, with an R2 value of 0.330. All of the above factors with the exception of the type of robot system and location of dominant myoma were related to the console time. Age, parity, history of previous abdominal surgery, surgical indication, diameter, and FIGO classification were not associated with the TOT.Conclusion: With an accurate identification of the perioperative parameters above, we can improve the quality of RALM by counselling, selecting an appropriate patient selection, and preoperative planning.

Objectives: The present study aimed to analyze the clinicopathologic features and treatment of uSTUMP in a single institution. In addition, we described the obstetric outcomes after uterine-preserving surgery for uSTUMP.Methods and Materials: A retrospective chart review was performed of patients diagnosed with uSTUMP between January 2000 and February 2018 at the Comprehensive Gynecologic Cancer Center, CHA Bundang Medical Center. We obtained data on the patients' demographics, treatment, therapeutic results, time to recurrence, disease-free and overall survival, and subsequent obstetric outcomes. The central pathology reviews were carried out by two pathologists specializing in gynecologic oncology.Result: A total of 19 patients diagnosed with uSTUMP were identified and included in the study. The mean age at diagnosis was 41 years (range 28-49 years). Frozen sections were performed in 11 patients including five patients during surgery. Nine of the 19 patients (47.4%) were treated by hysterectomy and 10 patients were initially treated by myomectomy. The mean follow-up period was 47 months (range 6-209 months). Two patients (10.5%; 2/19) experienced recurrence. Although not defined as recurrence in the present study criteria, one patient had a secondary diagnosis of atypical leiomyoma one year after the initial diagnosis of uSTUMP. Seven patients requested uterine-preserving treatment, five of whom wanted to become pregnant. Three of them (3/5; 60%) successfully delivered live birth to full term by Cesarean section without complications such as abortion, preterm delivery or uterine rupture, and tumor recurrence.Conclusions: The present study describes the clinicopathologic data of uSTUMP patients. Our results suggest a uSTUMP recurrence of 10.5%, comparable to previous reports. Although there is a possibility of malignant recurrence, fertility-preserving management is worth attempting because of relatively low affected age with careful close follow-up.

Objective: The objective of this study was to investigate the incidence of unexpected uterine malignancy (UUM) diagnosed after hysteroscopic surgery for presumed submucosal leiomyomas or endometrial polyps.Study Design: From the Korean national health insurance database between January 1, 2009 and December 31, 2015, we analyzed inpatient sample data that were extracted by a stratified random sampling (gender and age) method. We extracted women with or without UUM that was diagnosed after hysteroscopic surgery using diagnosis codes and procedure codes.Results: A total of 11,866 women who underwent hysteroscopic surgery were extracted from 4,476,495 women. The mean age of the patients who underwent hysteroscopic surgery was 37.8 ± 0.1 years. A hysteroscopic myomectomy or polypectomy was performed in 3498 and 8368 women, respectively. The incidence of UUM diagnosed after hysteroscopic myomectomy or polypectomy was 0.86% and 1.11%, respectively. The logistic regression analysis showed that the risk of UUM increased with age (Odds Ratio (OR), 1.61; 95% Confidence Interval (CI), 1.47-1.77; P < 0.001) and did not indicate hysteroscopic myomectomy or polypectomy (OR, 1.21; 95% CI, 0.93-1.55; P = 0.151).Conclusions: The incidence of UUM diagnosed after hysteroscopic myomectomy (0.86%) or polypectomy (1.11%) was higher than that of UUM diagnosed after hysterectomy (0.19%) or myomectomy (0.12%) for presumed benign leiomyoma. The incidence of UUM increased over the age of 50. [ABSTRACT FROM AUTHOR]

Controversy regarding psychological or psychiatric outcomes following hysterectomy still exists. The purpose of this study was to investigate the risk of postoperative psychiatric disorders in women with hysterectomy compared to that in women with uterus-conserving surgery for myomas by using population-based data from South Korea. This study was designed as a retrospective cohort study. We analyzed the National Health Insurance Service National Sample Cohort data including all administrative medical claims from 2002 to 2013. The study population, consisting of 9581 women, was defined as those diagnosed with uterine myoma who underwent medical procedures. The association between psychiatric and mood disorders and hysterectomy was assessed using Cox proportional hazard regression. During the study period, 1381 (14.4%) women experienced psychiatric disorders and 374 (3.9%) experienced mood disorders. The hazard ratio (HR) for psychiatric disorder was higher in women after hysterectomy than in women after uterus-conserving procedures (adjusted HR = 1.44; 95% CI = 1.27-1.64, p < 0.0001). In addition, the HR for mood disorders in women after hysterectomy was significantly higher than in women after uterus-conserving procedures (adjusted HR = 1.62; 95% CI = 1.26-2.08, p = 0.0002). Our study suggests that hysterectomy increased the risk of psychiatric disorders compared to uterus-conserving procedures in women with uterine myoma. Considering these findings, more focus on psychological responses in women following hysterectomy is needed, and appropriate psychosocial support or provisioning of information before or after procedures could reduce psychological distress.

Objective: In Korea, the Value Incentive Program (VIP) was first applied to selected clinical conditions in 2007 to evaluate the performance of medical institutes. We examined whether the condition-specific performance of the VIP resulted in measurable improvement in quality of care and in reduced medical costs.Design: Population-based retrospective observational study.Setting: We used two data set including the results of quality assessment and hospitalization data from National Health Claim data from 2011 to 2014.Participants: Participants who were admitted to the hospital for obstetrics and gynecology were included. A total of 535 289 hospitalizations were included in our analysis.Methods: We used a generalized estimating equation (GEE) model to identify associations between the quality assessment and length of stay (LOS). A GEE model based on a gamma distribution was used to evaluate medical cost. The Poisson regression analysis was used to evaluate readmission.Main Outcome Measures: The outcome variables included LOS, medical costs and readmission within 30 days.Results: Higher condition-specific performance by VIP participants was associated with shorter LOSs, decreases in medical cost, and lower within 30-day readmission rates for target and non-target surgeries. LOS and readmission within 30 days were different by change in quality assessment at each medical institute.Conclusions: Our findings contribute to the body of evidence used by policy-makers for expansion and development of the VIP. The study revealed the positive effects of quality assessment on quality of care. To reduce the between-institute quality gap, alternative strategies are needed for medical institutes that had low performance. [ABSTRACT FROM AUTHOR]

We aimed to compare the effects of ramosetron and palonosetron in the prevention of postoperative nausea and vomiting (PONV) in patients that received opioid-based intravenous patient-controlled analgesia (IV-PCA) after gynecological laparoscopy. We reviewed the electronic medical records of 755 adults. Patients were classified into two groups, ramosetron (group R, n=589) versus palonosetron (group P, n=166). Based on their confounding factors, 152 subjects in each group were selected after the implementation of propensity score matching. The overall incidence of PONV at postoperative day (POD) 0 was lower in group R compared to group P (26.9% versus 36.8%; P=0.043). The severity of nausea was lower in group R than in group P on postoperative day (POD) 0 (P=0.012). Also, the complete responder proportion of patients was significantly higher in group R compared to that in group P on POD 0 (P=0.043). In conclusion, ramosetron showed a greater efficacy in the prevention of postoperative nausea at POD 0 compared to palonosetron in patients after gynecological laparoscopy. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the cumulative recurrence rates of ovarian endometrioma among patients using a levonorgestrel-releasing intrauterine system (LNG-IUS) after conservative laparoscopic surgery.Methods: A retrospective review was conducted of premenopausal women who underwent conservative laparoscopic surgery for ovarian endometrioma and subsequent treatment with LNG-IUS at two gynecologic surgery centers in South Korea between January 1, 2007, and September 30, 2014. Eligible patients had no residual ovarian lesions before LNG-IUS insertion, underwent insertion within 12 months of primary surgery, and were followed up for at least 6 months afterwards. Recurrence was defined as a cystic mass (≥2 cm in diameter) detected by transvaginal ultrasonography.Results: Overall, 61 patients were included. The mean duration of follow-up was 42.9 ± 22.0 months (range 8-98). Recurrence of ovarian endometrioma was detected among 7 (11%) of the patients. On Kaplan-Meier analysis, the cumulative recurrence rates were 4.0%, 6.3%, and 25.5% at 24, 36, and 60 months after surgery, respectively. In multivariate analysis, nulliparity at surgery was the only risk factor for recurrence (hazard ratio 5.892, 95% confidence interval 1.139-30.484; P=0.034).Conclusion: Long-term maintenance therapy with LNG-IUS after conservative surgery might be a treatment option to consider to prevent ovarian endometrioma recurrence among premenopausal women.

Objective: To investigate pregnancy outcomes subsequent to ovarian pregnancy treated by surgery.Methods: A retrospective analysis was conducted of ovarian pregnancies that were treated by surgery at a hospital in Korea between January 1996 and December 2009.Results: Forty-nine women with ovarian pregnancies (1.6% of all ectopic pregnancies) were treated; 28 of these patients who were followed-up for more than a year were included in the study. The most common risk factor for ovarian pregnancy was endometriosis (42.9%). Accurate diagnosis of ovarian pregnancy was made preoperatively in 7 patients (25%). Of the 28 patients, 16 (57.1%) had subsequent pregnancies: 13 (46.4%) were intrauterine pregnancies and 3 (10.7%) were tubal pregnancies. However, no subsequent ovarian pregnancies occurred. In addition, only 1 patient had secondary infertility after surgery for ovarian pregnancy.Conclusions: After an ovarian pregnancy treated by surgery, the outcome of a subsequent pregnancy is reasonable; there is a high rate of successful subsequent pregnancy and a low rate of subsequent ectopic pregnancy or of infertility.

Background: Our objective was to evaluate risks of adverse obstetric outcomes in pregnancies with myoma(s) or in pregnancies following myomectomy.Methods: We analyzed the national health insurance database, which covers almost the entire Korean population, between 2004 and 2015. The risks of adverse pregnancy outcomes in pregnancies with myoma(s) or in pregnancies following myomectomy, compared to those in women without a diagnosed myoma, were analyzed in multivariate logistic regression analysis.Results: During the study period, 38,402 women with diagnosed myoma(s), 9890 women with a history of myomectomy, and 740,675 women without a diagnosed myoma gave birth. Women with a history of diagnosed myoma(s) and women with a history of myomectomy had significantly higher risks of cesarean section (aOR 1.13, 95% CI 1.1-1.16 and aOR 7.46, 95% CI 6.97-7.98, respectively) and placenta previa (aOR 1.41, 95% CI 1.29-1.54 and aOR 1.58, 95% CI 1.35-1.83, respectively), compared to women without a diagnosed myoma. And the risk of uterine rupture was significantly higher in women with previous myomectomy (aOR 12.78, 95% CI 6.5-25.13), compared to women without a diagnosed myoma, which was much increased (aOR 41.35, 95% CI 16.18-105.69) in nulliparous women. The incidence of uterine rupture was the highest at delivery within one year after myomectomy and decreased over time after myomectomy.Conclusions: Women with a history of myomectomy had significantly higher risks of cesarean section and placenta previa compared to women without a diagnosed myoma.
