Purpose: This study sought to explore whether the experience level of the first assistant surgeon influences perioperative organ injuries (ureteral, bladder, and intestinal injuries) in patients undergoing total laparoscopic hysterectomy (TLH) for benign diseases. We defined an experienced surgeon as a surgeon certified by the Skill Qualification Committee of the Japan Society of Gynecologic and Obstetric Endoscopy and Minimally Invasive Therapy or a surgeon with equivalent surgical skills. Methods: We reviewed our surgical registry database of TLH for benign indications between 2014 and 2020 and only selected cases performed by an experienced primary surgeon. Patients were divided into two groups based on the experience level of the first assistant. Inverse probability of treatment weighting by propensity score, which was adjusted for patient and procedure characteristics, was used to examine differences in perioperative organ injuries according to the experience level of the first assistant. Results: Among 1682 patients who underwent TLH, 18 organ injuries were found (0.83%). In the propensity score inverse probability of treatment weighting models, less experience of the first assistant had no significant impact on the occurrence of perioperative organ injuries (p = 0.348). Conclusion: In TLH for benign indications at our hospital, given an experienced primary surgeon, the inclusion of a less experienced first assistant does not negatively affect the occurrence of perioperative organ injuries.

Purpose: It is unknown whether surgery for endometriosis or recurrence of endometriosis affects obstetric outcomes. Methods: A total of 208 pregnant women with a history of endometriosis were analyzed. Patients who had endometriomas >3 cm and no history of laparoscopic surgery for endometriosis were defined as non‐surgery group (n = 60), while those who had a history of surgery for endometriosis (n = 148) were defined as surgery group. We investigated the obstetric outcomes in 208 patients according to with or without postoperative recurrence of endometriosis and the time from surgery to pregnancy. Results: Among 177 cases of on‐going pregnancy, in surgery group, there were lower prevalence of placenta previa compared with non‐surgery group (8.5% vs. 23.4%; p = 0.020). Subgroup analysis revealed a decreased prevalence of placenta previa in postoperative non‐recurrence group (6.0%: p = 0.007) compared with non‐surgery (23.4%) and postoperative recurrence group (28.6%). Placenta previa was more prevalent in the patients who got pregnant more than 2 years after surgery (20.0%) than the patients who got pregnant within 2 years (2.4%: p = 0.002). Multivariate analysis revealed that the surgery was associated with a reduction in placenta previa (OR: 0.32, 95% CI [0.11–0.90]; p = 0.032). Conclusions: Pregnancy within two years after laparoscopic surgery for endometriosis may reduce placenta previa.We conducted a retrospective study to investigate the impact of laparoscopic surgery for endometriosis and postoperative recurrence of endometriosis on subsequent pregnancy outcomes. For severe endometriosis patients (revised American Society for Reproductive Medicine classification; stage III or IV), we found that the surgery for endometriosis significantly decreased the prevalence of placenta previa, but it increased again when the time between surgery and pregnancy was more than 2 years.

Aim: Postlaparoscopic shoulder pain (SP), mainly caused by pneumoperitoneum with CO2, sometimes suffers patients. This study was aimed to analyze the backgrounds of SP after gynecologic laparoscopy to clarify the risk of SP. Methods: We analyzed answers of questionnaire about the degree of SP from 696 patients undergoing gynecologic laparoscopic surgery since 2014–2018. The questionnaire asks the degree of SP with numeric rating scale from 0 to 10, before and 3 days after operation. We defined cases in which postoperative score elevated more than three compared to preoperative score as SP(+). Analyzed backgrounds were age, parity, body mass index, operative method, operative duration and amount of hemorrhage. Statistics was performed by Fisher exact analysis as univariate analysis, and with logistic regression as multivariate analysis. All laparoscopic surgeries were performed under 10–12 mmHg in pressure of pneumoperitoneum with CO2. Results: Univariate analysis revealed categories 'less than 50 years old', and 'over 2 h' and 'over 3 h' in operative duration resulted significant high rate of SP(+). For these three factors, multivariate analysis resulted that "less than 50 years old' and 'over 3 h in operative duration' were significantly high. Conclusion: This study suggests that 'less than 50 years' old and 'over 3 h in operative duration' were risk factors of postlaparoscopic SP. To protect from SP after laparoscopy, some countermeasures should be necessary especially for these patients. [ABSTRACT FROM AUTHOR]

Aim: It is commonly thought that laparoscopic surgery leads to faster postoperative recovery for its low invasiveness. We evaluated postoperative quality of life (QOL) after laparoscopic myomectomy (LM) by using the Euro‐QOL 5 dimension (EQ‐5D) score and analyzed its relationship to surgical factors. Methods: Between 2014 and 2016, 541 patients underwent LM at our institution. We included 86 patients in the final analysis (16% response rate) who replied to the EQ‐5D questionnaire, in order to investigate postoperative QOL. We evaluated patients' EQ‐5D score before the operation and on the 3rd, 7th, 14th, 21st and 28th postoperative day (POD). We investigated the degree of correlation between the EQ‐5D score and four surgical characteristics (operation time, intraoperative bleeding, number of resected myomas and weight of specimen). We examined correlation between EQ‐5D scores and chief complaints such as hypermenorrhea, dysmenorrhea, other pain, myoma enlargement, palpable tumor and desire for childbearing. We also examined correlation between EQ‐5D scores and other factors such as patient's age, infertility, history of abdominal surgery, marriage and body mass index. Results: Full recovery, defined as an EQ‐5D score of 1.0, was reported 2.3% of patients by POD3, 18.6% by POD7, 58.1% by POD14, 73.3% by POD21 and 86.0% by POD28. Longer duration of operation correlated weakly with poor recovery on POD3. Intraoperative bleeding, number of resected myomas and weight of the specimen did not significantly influence EQ‐5D score. There was no correlation between chief complaints or other factors mentioned above and EQ‐5D score. Conclusions: More than a half of the patients undergoing LM included in our study reported full recovery of QOL after 2 weeks. The time to recover QOL was slightly influenced by the operation time. However, when LM was finished without any complications, postoperative QOL eventually seemed to improve regardless of the surgical characteristics such as operation time, intraoperative bleeding, number of resected myomas and weight of specimen.

Surgical strategies for the treatment of uterine artery pseudoaneurysm (UAP) include transarterial embolization and ultrasound-guided low-dose thrombin injection. Such strategies, however, have limitations and include the risk of ischemic damage to the uterus. We report a case of UAP treated with a new hysteroscopic and laparoscopic technique. A 29-year-old G1P0 woman with spontaneous abortion was transferred to the present institution because of hemorrhagic shock. We diagnosed ruptured UAP on transvaginal ultrasound with color Doppler. Emergency laparoscopic temporary clamping of the bilateral uterine arteries was done to reduce the bleeding, and transcervical resection to stop the hemorrhaging and to collect the pseudoaneurysm tissue. After surgery, blood flow to the myometrium was monitored on ultrasound. By postoperative day 48, normal menstruation had restarted, and no intrauterine adhesions were observed. On pathology of the UAP, a dilated spiral artery without its characteristic elastic fibers was identified. This surgical approach may help preserve fertility and allow for pathological diagnosis of UAP. [ABSTRACT FROM AUTHOR]
