Effect of Preoperative Bilateral Ultrasound-guided Quadratus Lumborum Nerve Block on Quality of Recovery after Minimally Invasive Hysterectomy in an Enhanced Recovery after Surgery (ERAS) Setting.

STUDY OBJECTIVE: To assess the effect of preoperative bilateral ultrasound-guided quadratus lumborum nerve block (QLB) on quality of recovery after minimally invasive hysterectomy, in an enhanced recovery after surgery setting. DESIGN: Randomized, controlled, double-blinded trial (Canadian Task Force level I). SETTING: University-affiliated tertiary medical center. PATIENTS: All women undergoing an elective robotic or laparoscopic hysterectomy. Women with chronic pain, chronic anticoagulation, and body mass index >50 kg/m2 were excluded. INTERVENTION: Patients were randomized with a 1:1 allocation, to one of the following 2 arms, and stratified based on robotic versus laparoscopic approach. 1. QLB: QLB (bupivacaine) + sham local trocar sites infiltration (normal saline) 2. Local infiltration: sham QLB (normal saline) + local infiltration (bupivacaine) MEASUREMENTS AND MAIN RESULTS: The primary outcome was defined as the quality of recovery score based on the validated questionnaire Quality of Recovery, completed 24 hours postoperatively. Secondary outcomes included dynamic pain scores, accumulated opioid consumption up to 24 hours, postoperative nausea and vomiting, surgical complications, length of hospital stay, time to first pain medication administration in the postanesthesia care unit, and adverse events. A total of 76 women were included in the study. Demographic characteristics were similar in both groups. Median age was 44 years (interquartile range 39-50), 47% of the participants were African American, and mean body mass index was 32.8 kg/m2 (standard deviation [SD] 8.1). The mean Quality of Recovery score was 179.1 (SD ± 10.3) in the QLB and 175.6 (SD ± 9.7) for the local anesthesia group (p = .072). All secondary outcomes were comparable between groups. CONCLUSIONS: QLBs do not significantly improve quality of recovery after elective robotic or laparoscopic hysterectomy compared with local anesthetic port site infiltration.

24-Hour Compared With 12-Hour Mifepristone-Misoprostol Interval for Second-Trimester Abortion: A Randomized Controlled Trial.

OBJECTIVE: To compare 24-hour and 12-hour mifepristone-to-misoprostol intervals for second-trimester medication abortion. METHODS: We conducted a prospective randomized controlled trial. Participants were allocated to receive mifepristone either 24 hours or 12 hours before misoprostol administration. The primary outcome was the time from the first misoprostol administration to abortion (induction time). Secondary outcomes included the time from mifepristone to abortion (total abortion time); fetal expulsion percentages at 12, 24, and 48 hours after the first misoprostol dose; side effects proportion; and pain and satisfaction scores. A sample size of 40 per group (N=80) was planned to compare the 24- and 12-hour regimens. RESULTS: Eighty patients were enrolled between July 2020 and June 2023, with 40 patients per group. Baseline characteristics were comparable between groups. Median induction time was 9.5 hours (95% CI, 10.3-17.8 hours) and 12.5 hours (95% CI, 13.5-20.2 hours) in the 24- and 12-hour interval arms, respectively ( P =.028). Median total abortion time was 33.0 hours (95% CI, 34.2-41.9 hours) and 24.5 hours (95% CI, 25.7-32.4 hours) in the 24- and 12-hour interval groups, respectively ( P <.001). At 12 hours from misoprostol administration, 25 patients (62.5%) in the 24-hour arm and 18 patients (45.0%) in the 12-hour arm completed abortion ( P =.178). At 24 hours from misoprostol administration, 36 patients (90.0%) in the 24-hour arm and 30 patients (75.0%) in the 12-hour arm had complete abortion ( P =.139). The need for additional medication or surgical treatment for uterine evacuation, pain scores, side effects, and satisfaction levels were not different between groups. CONCLUSION: A 24-hour mifepristone-to-misoprostol regimen for medication abortion in the second trimester provides a median 3-hour shorter induction time compared with the 12-hour interval. However, the median total abortion time was 8.5-hours longer in the 24-hour interval regimen. These findings can aid in shared decision making before medication abortion in the second trimester.

The association between BMI and continuity of etonogestrel (ENG)-releasing implant.

OBJECTIVE: The etonogestrel-releasing implant is a long-acting reversible contraception that is recommended by the Food and Drug Administration for 3 years and has been proven to be highly effective and convenient. Adverse effects including irregular bleeding patterns, weight gain, and acne are reported to be the main reasons for treatment discontinuation. The aim of this study is to learn the association between body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) and the incidence of side effects and adherence to treatment. METHODS: This is a retrospective cohort study, conducted at a single university-affiliated medical clinic, including all women who underwent etonogestrel-releasing implant (Nexplanon®; New Jersey, USA, Organon USA Inc., Merck and Co) insertion between January 2019 and December 2021. Cases where abnormalities were reported during the insertion procedure or missing data were excluded from the study. Information on patients' demographic, medical history, obstetric and gynecological history, and follow-up was collected from electronic medical files. The primary outcome was defined as the rate of implant removal in the different obesity classes. Data are presented as median and interquartile range. The study was approved by institutional review board. RESULTS: The study population included 1318 women, of whom 466 (35%) requested early removal of the implant. Women's demographic and clinical characteristics were comparable between women who requested early removal and those with full-length treatment. The median time for early removal was 12 (6-20) months from insertion. Irregular bleeding was the most frequent reason for early removal in both groups and was more than twice as prevalent in the early removal group (239 [51.29%] vs 193 [22%], P = 0.001). The early removal group had fewer obese women (BMI ≥30) compared with women who had full-length treatment (163 [31.8%] vs 350 [68.2%], P = 0.03), with comparable rates of class 3 obesity women (BMI ≥40) (P = 0.68). Multi-regression logistic analysis including age, BMI, parity and side effects found that the presence of side effects is the only independent predictor significantly associated with early implant removal (B = 1.74, P = 0.04). CONCLUSIONS: Continuation of etonogestrel-releasing implant contraception treatment was associated with the presence of side effects that were more often reported in non-obese women. BMI was not found to be a significant factor influencing adherence to treatment.

Excess use of surgical supplies in minimally invasive benign gynecology surgery: an observational study.

BACKGROUND: Single-use materials and equipment are regularly opened by the surgical team during procedures but left unused, potentially resulting in superfluous costs and excess environmental waste. OBJECTIVE: This study aimed to estimate the excess use of surgical supplies in minimally invasive benign gynecologic surgeries. STUDY DESIGN: This is a prospective observational study conducted at a university-affiliated single tertiary medical center. Designated study personnel were assigned to observe surgical procedures performed during July to September 2022. Surgical teams were observed while performing surgeries for benign indications. The teams were not informed of the purpose of the observation to avoid potential bias. Disposable materials and equipment opened during the procedure were documented. Excess supplies were defined as those opened but left unused before being discarded. Costs per item of the excess supplies were estimated on the basis of material and equipment costs provided by the hospital. RESULTS: A total of 99 surgeries were observed, including laparoscopic (32%), robotic (39%), hysteroscopic (14%), vaginal (11%), and laparotomy procedures (3%). Excess use of surgical supplies was documented in all but one procedure. The total cost across all surgeries reached $6357. The contained tissue extraction bag was the most expensive item not used (Applied Medical, Rancho Santa Margarita, CA; $390 per unit) in 4 procedures, contributing 25.54% to the total cost. Raytec was the most common surgical waste, with a total of n=583 opened but unused (average n=5.95 per surgery). A significant difference was found in the rate of excess supplies across the surgical approaches, with robotic surgery contributing 52.19% of the total cost (P=.01). CONCLUSION: Excess use of disposable materials and equipment is common in minimally invasive benign gynecologic surgeries and contributes to superfluous costs and excess environmental waste. It is predominantly attributed to the opening of inexpensive materials that are left unused during the procedure. Increased awareness of costs and generated waste may reduce excess use of surgical supplies and should be further explored in future research.

The association of endometrial closure during cesarean section to the risk of developing uterine scar defect: a randomized control trial.

PURPOSE: The surgical technique for uterine closure following cesarean section influences the healing of the cesarean scar; however, there is still no consensus on the optimal technique regarding the closure of the endometrium layer. The aim of this study was to compare the effect of closure versus non-closure of the endometrium during cesarean section on the risk to develop uterine scar defect and associated symptoms. METHODS: A randomized prospective study was conducted of women undergoing first elective cesarean section at a single tertiary medical center. Exclusion criteria included previous uterine scar, preterm delivery and dysmorphic uterus. Women were randomized for endometrial layer closure versus non-closure. Six months following surgery, women were invited to the ambulatory gynecological clinic for follow-up visit. 2-D transvaginal ultrasound examination was performed to evaluate the cesarean scar characteristics. In addition, women were evaluated for symptoms that might be associated with uterine scar defect. Primary outcome was defined as the residual myometrial thickness (RMT) at the uterine cesarean scar. Data are presented as median and interquartile range. RESULTS: 130 women were recruited to the study, of them follow-up was achieved in 113 (86.9%). 61 (54%) vs. 52 (46%) of the women were included in the endometrial closure vs. non-closure groups, respectively. Groups were comparable for patient's demographic, clinical characteristics and follow-up time for postoperative evaluation. Median RMT was 5.3 (3.0-7.7) vs. 4.6 (3.0-6.5) mm for the endometrial closure and non-closure groups, respectively (p = 0.38). Substantially low RMT (< 2.5 mm) was measured in four (6.6%) women in the endometrial closure group and three (5.8%) of the women in the non-closure group (p = 0.86). All other uterine scar sonographic measurements, as well as dysmenorrhea, pelvic pain and intermenstrual bleeding rates were comparable between the groups. CONCLUSION: Closure versus non-closure of the endometrial layer during cesarean uterine incision repair has no significant difference in cesarean scar characteristics and symptom rates at 6 months follow-up.

The association between uterine scar defect (niche) and the presence of symptoms.

RESEARCH QUESTION: Is there association between the presence of a uterine niche and the presence of symptoms? DESIGN: This cross-sectional study was conducted at a single tertiary medical centre. All women who underwent Caesarean section from January 2017 to June 2020 were invited to the gynaecological clinics, and requested to complete a questionnaire regarding symptoms related to the presence of a niche (heavy menstrual bleeding, intermenstrual spotting, pelvic pain, infertility). Transvaginal two-dimensional ultrasonography was performed to assess the uterus and uterine scar characteristics. The primary outcome was defined as the presence of a uterine niche, evaluated by length, depth, residual myometrial thickness (RMT) and ratio between the residual myometrial thickness (RMT) and adjacent myometrial thickness (AMT). RESULTS: Of 524 women who were eligible and scheduled for evaluation, 282 (54%) completed the follow-up; 173 (61.3%) were symptomatic and 109 (38.6%) asymptomatic. Niche measurements, including RMT/AMT ratio, were comparable between the groups. In a sub-analysis of each symptom, heavy menstrual bleeding and intermenstrual spotting were associated with reduced RMT (P = 0.02 and P = 0.04, respectively) compared with women with normal menstrual bleeding. An RMT less than 2.5 mm was significantly more prevalent in women reporting heavy menstrual bleeding (11 [25.6%] versus 27 [11.3%]; P = 0.01] and new infertility (7 [16.3%] versus 6 [2.5%]; P = 0.001]. In logistic regression analysis, infertility was the only symptom associated with an RMT less than 2.5 mm (B = 1.9; P = 0.002). CONCLUSIONS: A reduced RMT was found to be associated with heavy menstrual bleeding and intermenstrual spotting, while values below 2.5 mm were also associated with infertility.

The effects of Covid-19 mRNA vaccine on adolescence gynecological well-being.

KEY MESSAGE: Menstruation of adolescent girls might be influenced by Covid-19 mRNA vaccine, however, the ovarian reserve estimated by AMH is not compromised. BACKGROUND: Recent studies have suggested that the acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccine causes menstrual abnormalities which led to concerns regarding its influence on the reproductive system. This study aims to investigate the influence of the SARS-CoV-2 mRNA vaccine on gynecologic well-being and future fertility of adolescent girls. METHODS: This is a prospective cohort study conducted at a university affiliated medical center between June and July 2021. Adolescent girls aged 12-16 years who were vaccinated by two Pfizer-BioNTech Covid-19 vaccines (21 days apart) were included in the study. All participants completed a computerized questionnaire regarding their general medical and gynecological background at recruitment and 3 months later. Blood samples were collected for AMH levels before and 3 months following the first mRNA vaccine RESULTS: The study group consisted of 35 girls, and of them, follow-up was completed by questionnaire and AMH sampling in 35 (90%) and 22 (56%) girls, respectively. Among the 22/35 girls who reported regular menstruation before vaccination, seven (31.8%) experienced irregularities post-vaccination. Four of the eight pre-menarche girls included in the study reported on menarche on follow-up. Median AMH levels were 3.09 (IQR 1.96-4.82) µg/L and 2.96 (2.21-4.73) µg/L at baseline and after 3 months, respectively (p = 0.07). After controlling for age, BMI and presentation of side effects, no association was demonstrated to the change in AMH levels (AMH2-AMH1). CONCLUSIONS: Although menstruation of adolescent girls might be influenced by Covid-19 mRNA vaccine, it seems that the ovarian reserve estimated by AMH is not compromised. CLINICAL TRIAL REGISTRATION: National Institutes of Health (NCT04748172).

Perinatal Outcome following the Suspension of Intrapartum Oxygen Treatment.

OBJECTIVE: This study aimed to evaluate whether the suspension of intrapartum maternal oxygen supplementation for nonreassuring fetal heart rate is associated with adverse perinatal outcomes. STUDY DESIGN: A retrospective cohort study, including all individuals that underwent labor in a single tertiary medical center. On April 16, 2020, the routine use of intrapartum oxygen for category II and III fetal heart rate tracings was suspended. The study group included individuals with singleton pregnancies that underwent labor during the 7 months between April 16, 2020, and November 14, 2020. The control group included individuals that underwent labor during the 7 months before April 16, 2020. Exclusion criteria included elective cesarean section, multifetal pregnancy, fetal death, and maternal oxygen saturation <95% during delivery. The primary outcome was defined as the rate of composite neonatal outcome, consisting of arterial cord pH <7.1, mechanical ventilation, respiratory distress syndrome, necrotizing enterocolitis, intraventricular hemorrhage grade 3/4, and neonatal death. The secondary outcome was the rate of cesarean and operative delivery. RESULTS: The study group included 4,932 individuals, compared with 4,906 individuals in the control group. The suspension of intrapartum oxygen treatment was associated with a significant increase in the rate of composite neonatal outcome (187 [3.8%] vs. 120 [2.4%], p < 0.001), including the rate of abnormal cord arterial pH <7.1 (119 [2.4%] vs. 56 [1.1%], p < 0.01). A higher rate of cesarean section due to nonreassuring fetal heart rate was noted in the study group (320 [6.5%] vs. 268 [5.5%], p = 0.03).A logistic regression analysis revealed that the suspension of intrapartum oxygen treatment was independently associated with the composite neonatal outcome (adjusted odds ratio = 1.55 [95% confidence interval, 1.23-1.96]) while adjusting for suspected chorioamnionitis, intrauterine growth restriction, and recent coronavirus disease 2019 exposure. CONCLUSION: Suspension of intrapartum oxygen treatment for nonreassuring fetal heart rate was associated with higher rates of adverse neonatal outcomes and urgent cesarean section due to fetal heart rate. KEY POINTS: · The available data on intrapartum maternal oxygen supplementation are equivocal.. · Suspension of maternal oxygen for nonreassuring fetal heart rate during labor was associated with adverse neonatal outcomes.. · Oxygen treatment might still be important and relevant during labor..

Prophylactic salpingectomy with delayed oophorectomy as a two-staged alternative for primary prevention of ovarian cancer in BRCA1/2 mutation carriers: women's point of view.

OBJECTIVE: This study aimed to determine BRCA -mutation carrier women's interest and acceptability of participating in a study examining prophylactic salpingectomy with delayed oophorectomy (PSDO) as an alternative to the current recommendation for bilateral salpingo-oophorectomy for risk reduction. METHODS: This is a cross-sectional questionnaire-based study. All women visiting the high-risk clinics for hereditary breast and ovarian cancer in a single tertiary medical center were asked to complete a questionnaire concerning the two-stage approach from October 2018 to December 2019. Before completing the questionnaire, detailed explanation was given by a senior physician regarding the procedure, related background, possible risks, and benefits. RESULTS: The study population included 293 women, of whom 183 (62.4%) were BRCA1 mutation carriers, 97 (33.1%) were BRCA2 mutation carriers, and 13 (4.4%) had unknown familial mutation. Risk-reducing surgery was completed in 160 (55.17%) of the women. First-degree and second-degree family history was reported in 166 (57.24%) and 52 (17.9%) of the women, respectively. Among women surveyed, more than half of the women (n = 66 [51%]) who had yet to undergo risk-reducing surgery reported interest in having PSDO. Similarly, among those who had already received prophylactic surgery, 64 (40%) also considered PSDO to be an acceptable alternative. Multivariate logistic regression analysis found family history of related malignancies to be the only independent factor associated with reduced interest in a study of PSDO (odds ratio, 0.15 [95% confidence interval, 0.29-0.77]; P = 0.02). CONCLUSIONS: Overall, BRCA -mutation carrier women indicated interest in PSDO risk-reducing surgery, taking into consideration the potential additional risk. These findings suggest that a clinical study exploring the equivalence of PSDO as alternative treatment is feasible.

Proteomic signature for detection of high-grade ovarian cancer in germline BRCA mutation carriers.

No current screening methods for high-grade ovarian cancer (HGOC) guarantee effective early detection for high-risk women such as germline BRCA mutation carriers. Therefore, the standard-of-care remains risk-reducing salpingo-oophorectomy (RRSO) around age 40. Proximal liquid biopsy is a promising source of biomarkers, but sensitivity has not yet qualified for clinical implementation. We aimed to develop a proteomic assay based on proximal liquid biopsy, as a decision support tool for monitoring high-risk population. Ninety Israeli BRCA1 or BRCA2 mutation carriers were included in the training set (17 HGOC patients and 73 asymptomatic women), (BEDOCA trial; ClinicalTrials.gov Identifier: NCT03150121). The proteome of the microvesicle fraction of the samples was profiled by mass spectrometry and a classifier was developed using logistic regression. An independent cohort of 98 BRCA mutation carriers was used for validation. Safety information was collected for all women who opted for uterine lavage in a clinic setting. We present a 7-protein diagnostic signature, with AUC >0.97 and a negative predictive value (NPV) of 100% for detecting HGOC. The AUC of the biomarker in the independent validation set was >0.94 and the NPV >99%. The sampling procedure was clinically acceptable, with favorable pain scores and safety. We conclude that the acquisition of Müllerian tract proximal liquid biopsies in women at high-risk for HGOC and the application of the BRCA-specific diagnostic assay demonstrates high sensitivity, specificity, technical feasibility and safety. Similar classifier for an average-risk population is warranted.

Trial of labor after cesarean delivery for estimated large for gestational age fetuses: A retrospective cohort study.

OBJECTIVE: Although ultrasonographic estimation of fetal weight ≥90th percentile is not associated with a greater risk for uterine rupture, trial of labor after cesarean delivery (TOLAC) is considered relatively contraindicated for macrosomic fetuses. Hence, when an estimated fetal weight of 4000 g is detected, TOLAC is usually avoided.Our aim was to evaluate the obstetrical outcome and safety of TOLAC in women with estimated large for gestational age fetuses (eLGA) (≥90th percentile). STUDY DESIGN: Our retrospective cohort study encompassed all pregnant women with an estimated fetal weight ≥90th percentile for gestational age, admitted to a single tertiary care center between January 2012-July 2017 for TOLAC. RESULTS: 1949 women met the inclusion criteria; 78 (4%) eLGA and 1871 (96%) controls. Fifty-five (70.5%) women in the study group had experienced a successful vaginal delivery compared to 1506 (80.5%) of the controls (p = 0.03). The rate of obstetrical complications, including scar dehiscence, uterine rupture, a 3rd/4th degree perineal tear or shoulder dystocia were comparable. The rate of post-partum hemorrhage (PPH) increased in the study group compared to the controls (7.7 % vs.1.7%; p = 0.001). CONCLUSION: TOLAC for eLGA fetuses can be considered safe, however, lower successful rates of vaginal births after a cesarean delivery and an increased PPH rate, may be expected.

Should expectant management of heterotopic pregnancy be considered?

KEY MESSAGE: Both expectant and interventional managements are acceptable in selected cases, when heterotopic pregnancy is diagnosed, with high ongoing intra-uterine pregnancy rate and term deliveries. PURPOSE: Heterotopic pregnancy, though relatively rare, is potentially a life-threatening condition. The aim of the study is to compare expectant versus interventional management of heterotopic pregnancies. METHODS: This is a retrospective cohort study including all women diagnosed with heterotopic pregnancy on ultrasound from March 2011 to December 2020 in a single medical center. Expectant and interventional management outcomes were compared. Primary outcome was defined as live birth. RESULTS: Forty-one women were diagnosed with heterotopic pregnancy during the study period. Management was expectant in 10 (24.4%) and interventional in 31 (75.6%) of the women. Expectant management was considered when the patient was stable, and the attending physician decided that the ectopic pregnancy did not continue to develop. Interventions included laparoscopic salpingectomy (n = 26), laparoscopic cornual resection (n = 2), laparotomic cornual resection (n = 1) and gestational sac aspiration (n = 2). The intra-uterine pregnancy continued to develop in 6 (60.0%) and 22 (81.5%) of the women in the expectant and interventional groups, respectively (p = 0.52). All women managed expectantly reached term delivery, as opposed to 17/22 (77.3%) in the intervention management group (p = 0.60). Multivariate analysis found serum ß-hCG level as the only independent parameter associated with ongoing pregnancy rate (B = 0.001, p = 0.04). CONCLUSIONS: Both expectant and interventional management were found to be acceptable when heterotopic pregnancy was diagnosed, with high ongoing intra-uterine pregnancy rate and term deliveries.

Clinical features of isolated Fallopian tube torsion: evidence from a large series.

We aimed at studying isolated Fallopian tube torsion (IFTT) in a relatively large cohort of women and to evaluate different features of IFTT in comparison to a large cohort of women with non-IFTT adnexal torsion (NIAT). This was a retrospective cohort study. We included women with surgically confirmed ovarian and/or Fallopian tube torsion between March 2011 and June 2020. Fifty-four cases of IFTT were surgically confirmed during the study period and were compared to 422 surgically confirmed NIAT. The rate of controlled ovarian hyperstimulation treatments, current pregnancy, and vomiting was lower in the IFTT group compared with the NIAT group. Cervical tenderness and vaginal discharge were more common in the IFTT group. Oedematous and enlarged ovaries were less common in the IFTT group. In multivariate regression analysis, the following factors were independently associated with IFTT: (i) vaginal discharge [adjusted odds ratio (aOR) 95% CI 8.16, 1.98-33.55]; (ii) cervical motion tenderness (aOR 95% CI 2.71, 1.01-7.29); (iii) fertility treatments (aOR 95% CI 0.26, 0.70-0.77); (iv) previous abdominal surgery (aOR 95% CI 0.46, 0.22-0.96); (v) vomiting (aOR 95% CI 0.38, 0.19-0.76); and (vi) enlarged ovary (aOR 95% CI 0.34, 0.18-0.65). In conclusion, we have identified factors positively and negatively associated with IFTT in a large cohort of women with adnexal torsion.

Pediatric and adolescent females are at higher risk of adnexal torsion recurrence-A large-scale retrospective study.

AIM: Recurrence of adnexal torsion (rAT) is reported mainly in small series. Normal and small appearing ovaries are associated with an increased risk for rAT. Nevertheless, updated data of larger cohorts is lacking. We aimed to investigate the predictors for rAT in a cohort of women who had surgical intervention for primary adnexal torsion (pAT). METHODS: A retrospective case-control study from a single institution between 2011 and 2020. Women with a primary occurrence of surgically proven adnexal torsion were included. We compared those who had experienced rAT to those who had not. Univariate and multivariate analysis were performed to study independent predictors for rAT. RESULTS: Overall, 358 women were included. Of those, 35 (9.8%) had a rAT. Women who experienced rAT were younger (mean age 26 vs. 30 years, p = 0.01). Women experiencing rAT had smaller mean ovarian cyst diameter in the pAT episode (42 vs. 59 mm. p < 0.001). Performance of laparoscopic detorsion was only associated with rAT (odds ration [OR] 95% confidence interval [CI] 2.13 [1.02-4.42], p = 0.03), while the performance of additional cystectomy was negatively associated with rAT (OR 95% CI 0.10 [0.01-0.79], p = 0.006). Multivariate analysis demonstrated that age ≤15 and smaller cyst diameter at pAT were independently associated with the risk for rAT (aOR 95% CI 5.0 [1.09-23.2] and 1.47 [1.08-2.0], for every 10 mm decrease in cyst diameter, respectively). CONCLUSIONS: Adolescents and pediatric females and women with smaller ovarian cysts at pAT are at higher risk for future recurrence of adnexal torsion.

Office Operative Hysteroscopy for the Management of Retained Products of Conception.

The aim of this study was to compare office to conventional operative hysteroscopy for the treatment of retained products of conception (RPOC). This retrospective cohort study included all women who underwent hysteroscopy due to RPOC between January 2018 and December 2019, in a single tertiary medical care center. Exclusion criteria for hysteroscopy included the following: (1) proximity to delivery (up to 3 weeks); (2) hemodynamic instability; (3) active massive bleeding; and (4) genital tract infection. See-and-treat hysteroscopy (study group) outcomes were compared to operative hysteroscopy (controls). Data were collected from women's medical records. Primary outcome was defined as successful removal of all suspected RPOC with no need for additional intervention. Data are presented as median and interquartile range. During the study period, 222 women underwent hysteroscopy due to RPOC. Of them, 138 (62%) and 84 (38%) underwent see-and-treat and operative hysteroscopy, respectively. Symptomatic women were more commonly referred to operative hysteroscopy (60 (71%) vs. 54 (39%); p = 0.001). Maximal diameter of the suspected finding was smaller both by ultrasound examination (13 (10-18) vs. 18 (13-32) mm; p = 0.001) and by surgeon estimation during diagnostic hysteroscopy (12 (8-20) vs. 20 (14-30) mm; p = 0.001), in the see-and-treat compared to the operative hysteroscopy group, respectively. While comparing success rate between groups, no difference was observed. Sub-analysis by the maximal diameter of RPOC findings revealed that see-and-treat success rate is reduced as the RPOC is larger. Success rate was high and comparable to operative hysteroscopy for findings ≤ 2 cm (102/117 (87%) vs. 49/54 (91%); p = 0.79). Nevertheless, for RPOC > 2 cm, success was significantly more frequent in the operative hysteroscopy group (28/30 (93%) vs. 9/16 (57%); p = 0.002). This finding was supported by logistic regression analysis that found maximal diameter of RPOC as the only parameter associated with success rate (B = 0.96; p = 0.03). Office operative hysteroscopy is a feasible treatment option for the removal of RPOC when maximal diameter is taken under consideration due to its association to success rate.Clinical trial registration: The study protocol was approved by the "Sheba Medical Center" Review Board (ID 5200-18 SMC) on June 24, 2018.

Placenta accreta spectrum in subsequent pregnancy following myomectomy.

PURPOSE: To compare the prevalence of placental abnormalities in pregnancy following different modes of operative myomectomy. METHODS: A retrospective cohort study, including all women after myomectomy that gave birth in a single tertiary care center from February 2011 to January 2019. Data was collected from the patients' medical files and completed by telephone questionnaire. Patients were stratified to 3 groups, according to the mode of operative myomectomy (laparotomy, laparoscopy, hysteroscopy). Groups were compared for women demographics, fibroid's characteristics, operative management, post-operative placental evaluation and delivery characteristics. Primary outcome was defined as the need for any intervention for placental separation during the third phase of the delivery. RESULTS: Two hundred forty one women met inclusion criteria. Complete follow-up was achieved in 199 (82.57%) women, of whom 82, 89, and 28 underwent laparoscopic, laparotomy and hysteroscopic myomectomy, respectively. There were no in-between groups differences in women's age, BMI, and gravidity. Disruption of the endometrial cavity during laparoscopy and laparotomy was reported in 3 (3.6%) and 7 (7.8%) cases, respectively (p = .21). During the subsequent pregnancy following myomectomy, placenta accreta spectrum disorder was suspected in only one woman in each of the study groups (p = .63). Placenta previa was low and comparable between groups. Vaginal delivery rate was significantly higher in the hysteroscopy group, as compared to the laparoscopy or the laparotomy groups [11 (36.3%) vs. 5 (6.1%) vs. 4 (4.5%); p = .001], with significantly lower need for manual lysis of the placenta [11(39.0%) vs. 51 (62.1%) vs. 62 (69.7%); p = .01] and further interventions for blood loss control. CONCLUSIONS: Subsequent pregnancy following surgical myomectomy was not found to be associated with higher prevalence placental abnormality. Furthermore, other than manual lysis, the different modes of myomectomy did not necessitate any further intervention for complications associated with abnormal placentation requiring intervention. KEY MESSAGE: Subsequent pregnancy following surgical myomectomy is not associated with higher prevalence of placental abnormality.

Uterine exteriorization versus intraperitoneal repair in primary and repeat cesarean delivery: a randomized controlled trial.

PURPOSE: The aim of this study is to evaluate the effect of uterine exteriorization versus intraperitoneal repair, in first compared to repeat cesarean delivery. METHODS: A prospective randomized control single-blinded trial conducted in a single tertiary center between March 2014 and March 2015, including 32 and 63 women in first and recurrent cesarean sections, respectively. Inclusion criteria were elective operation and gestational age ≥37 weeks. Operative outcomes were compared between the groups including mean operative time, blood loss, hypotension, perioperative nausea and pain. Post-operative outcomes were further compared, including post-operative analgesia demand, first recognized bowel movement, nausea, length of hospital stay, fever, endometritis surgical site infection rate, and total satisfaction. RESULTS: During the study period, 45 and 50 women were designated for uterine exteriorization and intraperitoneal uterine repair, respectively. Mean blood loss was 452 cc (±10.44) for the extraperitoneal compared to 540 cc (±29.83) for the intraperitoneal uterine repair group (p = .004). No other significant differences in either intraoperative or postoperative complications were demonstrated in and between the groups. CONCLUSION: Intraperitoneal repair of uterine incision is associated with higher operative blood loss compared to uterine exteriorization. No other differences in operative and postoperative complication rates were found between the groups.
