Introduction: Intraperitoneal retention of surgical instrument fragments may lead to severe complications. Therefore, such foreign bodies must be detected before surgery completion. We present a case with intraoperative breakage of a laparoscopic needle holder confirmed by a routine postoperative abdominal X-ray and review the literature regarding intraoperative laparoscopic instrument breakage. Case Report: A 58-year-old woman with stage IB1 cervical adenocarcinoma underwent a laparoscopic radical hysterectomy. Surgery was completed without major complications; however, an abdominal X-ray as a routine postoperative examination revealed a radiopaque shadow of approximately 3 mm corresponding to a broken part of the tissue-pad of the laparoscopic needle holder tip. It was successfully removed using laparoscopy with fluoroscopic guidance without further complications. According to the literature review, most of the instrument breakage were noticed during surgery as they were either obvious or impaired function. In our case, since the detached foreign body was extremely small and did not significantly affect needle holder function, it remained unnoticed until the postoperative X-ray was taken. Conclusion: Postoperative abdominal X-rays identify instrumental fragments infrequently; however, they may help detect intraperitoneal retention of foreign bodies and avoid serious complications following laparoscopic surgery.

Peritoneal dissemination is a predominant pattern of metastasis in patients with advanced ovarian cancer. Despite recent progress in the management strategy, peritoneal dissemination remains a determinant of poor ovarian cancer prognosis. Using various histological types of patient-derived ovarian cancer organoids, the roles of the apicobasal polarity of ovarian cancer cell clusters in peritoneal dissemination were studied. First, it was found that both ovarian cancer tissues and ovarian organoids showed apicobasal polarity, where zonula occludens-1 (ZO-1) and integrin beta 4 (ITGB4) served as markers for apical and basal sides, respectively. The organoids in suspension culture, as a model of cancer cell cluster floating in ascites, showed apical-out/basal-in polarity status, while once embedded in extracellular matrix (ECM), the organoids switched their polarity to apical-in/basal-out. This polarity switch was accompanied by the SRC kinase family (SFK) phosphorylation and was inhibited by SFK inhibitors. SFK inhibitors abrogated the adherence of the organoids onto the ECM-coated plastic surface. When the organoids were seeded on a mesothelial cell layer, they cleared and invaded mesothelial cells. In vivo, dasatinib, an SFK inhibitor, suppressed peritoneal dissemination of ovarian cancer organoids in immunodeficient mice. These results suggest SFK-mediated polarity switching is involved in peritoneal metastasis. Polarity switching would be a potential therapeutic target for suppressing peritoneal dissemination in ovarian cancer.

This multicenter, open-label, phase II study aimed to evaluate the efficacy and safety of paclitaxel-carboplatin, bevacizumab, and bevacizumab-based maintenance therapy for metastatic, recurrent, and persistent uterine cervical cancer.Patients with measurable diseases that were not adapted to regional therapies, such as surgery or radiotherapy, and were systematic chemotherapy-naïve were eligible. The participants received paclitaxel (175 mg/mSixty-nine patients were analyzed using our protocol. The median paclitaxel- carboplatin therapy duration was six cycles; 40% of patients received bevacizumab maintenance therapy. The median PFS was 11.3 months. The median OS was not reached; the median time to treatment failure was 5.9 months. The ORR was 79.7% [95% confidence interval (CI) 63.8-88.4]; 16 patients (23.2%) showed complete response (CR) and 39 patients (56.5%) showed partial response (PR). The median PFS was 14.3 months (95% CI 7.3-17 months) for the 25 patients who received maintenance therapy and 7.4 months (95% CI 6.1-11 months) for nonrecipients (p = 0.0449). Gastrointestinal perforation/fistulas occurred in four patients (5.6%), all of whom had a history of radiation therapy.Paclitaxel-carboplatin and bevacizumab therapy is an acceptable and tolerable treatment for advanced or recurrent cervical cancer.

Key Clinical Message We present the first case of the patient with skeletal metastasis of uterine cervical cancer which invaded the vertebral body and spinal canal, with consequent paralysis of the lower extremities.

Peritoneal inclusion cysts (PICs) often develop in post-operative patients. Since the incidence of adhesions is lower with laparoscopic surgery than with open surgery, PICs are less likely to occur in the former. Although post-operative adhesions or PICs rarely develop after laparoscopic surgery (such as total laparoscopic hysterectomy: TLH), we encountered two cases of giant PICs with abdominal pain after TLH. In Case 1, strong adhesion was already present when TLH was performed. Therefore, this case may have been predisposed to the development of adhesions in the abdominal cavity. However, no adhesions were observed during TLH in case 2, and there were no risk factors, such as pre-operative adhesions and endometriosis. Therefore, adhesions and PICs may develop even after TLH, and approaches need to be considered for their prevention.

Women in the reproductive age group diagnosed with cervical cancer can receive radical trachelectomy in case they wish to preserve fertility. However, the indication for this procedure in infertile women with cervical cancer is controversial depending on the underlying cause of infertility. Here, we present a case of a successful pregnancy following myomectomy accompanied with abdominal radical trachelectomy for an infertile woman with early cervical cancer. The patient was a 38-year-old nulliparous woman with a significant past medical history of infertility of unknown origin. She had been undergoing treatment with assisted reproductive technologies including artificial insemination and in vitro fertilization for over four years. During her treatment for infertility, she was diagnosed with stage IB1 cervical squamous cell carcinoma. She received abdominal radical trachelectomy and abdominal myomectomy in the same surgical procedure. Six months after the surgery, she went for the first embryo transfer and became pregnant. At 26 weeks of pregnancy, a male baby weighing 980 g was delivered with an Apgar score of 3/5/7 by cesarean section due to chorioamnionitis. The baby has received general care in a neonatal intensive care unit for four months and weighed 4520 g when discharged.

Uterine mesenchymal tumors other than leiomyosarcoma, carcinosarcoma, and endometrial stromal sarcomas are extremely uncommon. We describe a case of epithelioid angiosarcoma of the uterus and review previous literature on such rare tumors. A 48-year-old woman presented with a 1-year history of abdominal fullness and 10kg weight loss. Pelvic magnetic resonance imaging (MRI) revealed a huge (30×18cm) uterus accompanied by degeneration and necrosis. She underwent supracervical hysterectomy and right salpingo-oophorectomy. We postoperatively diagnosed the mass as an epithelioid angiosarcoma arising from a leiomyoma. Vasodilatation was observed within the range of 2 cm × several mm in the leiomyoma, and proliferation of atypical cells was observed covering the surface of the luminal side. The tumor showed a partly fine vascular structure and was associated with obvious nuclear atypia and mitotic figures. She received 6 courses of adjuvant chemotherapy with paclitaxel, epirubicin, and carboplatin, and there have been no signs of recurrence for 10 months.

To develop a new therapeutic strategy for taxane/platinum-resistant/refractory ovarian and primary peritoneal cancers, we evaluated the feasibility and efficacy of irinotecan and gemcitabine combination chemotherapy.Patients with taxane/platinum-resistant/refractory cancer received escalating doses of irinotecan and gemcitabine (level 1: 80 and 800 mg/mA total of 35 patients were enrolled. The recommended dose was defined as 100 mg/mCombination chemotherapy with irinotecan and gemcitabine represents a safe and effective treatment combination for taxane/platinum-resistant/refractory ovarian and primary peritoneal cancers.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rapidly progressive and often fatal pulmonary disease induced by tumor emboli within the small pulmonary arteries. PTTM presents clinically as progressive hypoxia and pulmonary hypertension. Most cases of PTTM are caused by an adenocarcinoma of the stomach. We present the first case report of PTTM caused by cervical squamous cell carcinoma. An 82-year-old woman presented with vaginal bleeding and exertional dyspnea. A cervical mass biopsy showed squamous cell carcinoma. Computed tomography revealed ground glass opacity of the bilateral peripheral lung fields. Hypoxia and pulmonary hypertension gradually worsened after admission. Treatment for acute heart failure was started, but was ineffective. She died of respiratory failure 31 days after admission. She was diagnosed at autopsy as having PTTM induced by cervical squamous cell carcinoma. PTTM needs to be considered in any patient with advanced cancer and lung-related issues to rule out metastatic disease, even in the absence of imaging findings.

Background: Postoperative surgical site infections (SSIs) are one of the most frequent complications after open abdominal surgery. Triclosan-coated sutures were said to be able to reduce its occurrence. In gynecologic surgery, SSIs of the vaginal stump are a frequent cause of postoperative fever. Double gloving is also said to contribute to the prevention of SSIs. We performed abdominal hysterectomy with double gloving and sutured the vagina stump with VICRYL PLUS ® , a Polyglactin 910 suture coated with triclosan, to prevent SSIs. We investigated whether triclosan-coated sutures coupled with double gloving could indeed reduce the incidence of SSIs following abdominal hysterectomy. Methods: We retrospectively reviewed 384 cases of abdominal hysterectomies operated in our department between April 2013 and March 2015. In the first period (from April 2013 to March 2014), we performed 195 operations with single gloving and sutured the vaginal stump with VICRYL ® (Polyglactin 910 suture without triclosan coat). In the second period (from April 2014 to March 2015), we performed 189 operations with double gloving and sutured the vaginal stump with VICRYL PLUS ® (Polyglactin 910 suture with triclosan coat). The primary outcome is the incidence of SSIs. Results: The two groups were comparable with respect to risk factors for SSIs. The incidences of SSIs in the first and second groups were 17 of 195 patients (8.7%) and eight of 189 patients (4.2%), respectively. The difference in the incidence of SSIs was not significant between the two groups (P = 0.097). The numbers of cases requiring postoperative antibiotic therapy in the first and second groups were 13 (6.7%) and 4 (2.1%). The incidence was higher in the control group (P = 0.045). None of the 189 cases needed drainage therapy or a re-operation. Conclusion: It is possible that triclosan-coated sutures coupled with double gloving are able to reduce SSIs and prevent SSI aggravation.

This study aims to present an impedance measurement method using a power converter to evaluate degradation of solar panels. The ac impedance method is used to evaluate electrochemical devices, such as fuel cells and batteries. Herein, we conducted experiments to measure the impedance frequency characteristics of photovoltaic panels under normal and partially shaded conditions. Results show that the impedance under a partially shaded condition is higher than that under a normal condition.

•Malignant peritoneal mesothelioma, particularly the sarcomatoid type, is rare and aggressive.•Accurate diagnosis by ascites cytology is difficult.•Histological examination such as laparoscopy aids in diagnosis.•There is no clear consensus treatment for MPM and an extensive research program is needed.

Malignant primary tumors arising in the uterine broad ligament are extremely rare, and only 26 cases have been reported to date. We describe 2 new cases of primary adenocarcinoma of the broad ligament, and we review the previous literature on such rare tumors. In Case 1, a 71-year-old woman presented with a 2-month history of increased yellow vaginal discharge and lower abdominal pain during bowel movement. Transvaginal sonography revealed a 6.5 cm mass located on the dorsum of the uterus and a 7.0 cm mass (with cystic and solid parts) near the right adnexa. We postoperatively diagnosed the mass as a high-grade serous carcinoma of the broad ligament (pT3cNXM0). The patient is currently receiving adjuvant chemotherapy with paclitaxel and carboplatin. In Case 2, during a complete medical checkup a 43-year-old woman was found to have a pelvic mass indicative of leiomyoma. Transvaginal sonography revealed a 3.8 cm mass located on the dorsum of the uterus. Following surgery, we diagnosed the mass as a clear cell adenocarcinoma of the broad ligament (pT2bN1M0). This patient is also now receiving adjuvant chemotherapy with paclitaxel and carboplatin.

Gemella morbillorum, a Gram-positive coccus facultative anaerobe, is part of the normal flora of the mucous membranes of the oropharynx, upper respiratory, gastrointestinal, and female genital tracts. However, this species can also cause serious infection. We herein report on a case of bacteremia, accompanied by peritonitis and pleuritis, in a 46-year-old immunocompetent female following a total laparoscopic hysterectomy for endometrial cancer. The case was successfully treated with antibacterial and antifungal agents.

A 50-year-old woman with abdominal fullness, lower abdominal pain, elevated serum CA125, and ascites, underwent neoadjuvant chemotherapy with 6 courses of PTX/CBDCA followed by total hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and intrapelvic peritoneal stripping based on a diagnosis of serous surface papillary carcinoma(SSPC) of the peritoneum. Complete response(CR)was shown after adjuvant chemotherapy with 3 courses of the same regimen. After 6 months, serum CA125 level re-increased and abdominal CT showed small low density areas in the patient's spleen and the perisplenic fat tissue. After the additional chemotherapy with 3 courses of PTX/CBDCA were performed based on a diagnosis of metastatic lesion from SSPC, anaphylactic shock occurred as the severe adverse event. The patient was given 9 more courses of the chemotherapy changed the regimen to PTX/CDDP. The splenic metastatic lesion had grown rapidly in the followed CT and then, laparoscopic splenectomy with peritoneal resection was performed based on a diagnosis of splenic metastasis from SSPC. The pathological examinations showed the tumor to be a splenic metastasis and peritoneal dissemination from SSPC. No recurrent lesion has been detected in the 9 months since removal of the splenic metastasis without adjuvant chemotherapy and the patient has survived for 4 years and 6 months since initial treatment.

Borderline ovarian tumors are benign but relatively large tumors that are often initially mistaken as ovarian cancers. We report three cases of stage I borderline ovarian tumors having massive ascites that we (preoperatively) suspected of being advanced ovarian cancer. The three patients (35, 47, and 73 years old) reported feeling fullness of the abdomen before consulting their gynecologist. By CT scan, they were diagnosed with a pelvic tumor accompanied by massive ascites, the diameters of which were 11, 20, and 11 cm, respectively. Postsurgical pathology showed all were stage I borderline ovarian tumors without dissemination; two were mucinous and one was serous. The amount of ascites was 6,300, 2,600, and 3,600 mL, respectively, and was serous in all. Cytodiagnosis of the ascites found that one was positive for tumor cells and two were negative. After resection of the mass, the ascites disappeared in all three cases. No pleural effusion was present at any time. The literature is reviewed concerning ascites and pleural effusions linked to ovarian tumors, and a supposition is forwarded of why pleural effusion presents sporadically in these cases.
