Reduction in Time from Admission to Operation of Women with Suspected Adnexal Torsion During the COVID-19 Pandemic.

BACKGROUND: Data regarding the management of adnexal torsion (AT) during the coronavirus disease 2019 (COVID-19) pandemic are scarce. OBJECTIVES: To study the effects of actions to limit the spread of COVID-19 on AT management. METHODS: We conducted a retrospective cohort study of all women who underwent laparoscopy for suspected AT between March 2011 and February 2021. We compared the COVID-19 pandemic period, (15 March 2020-2 August 2021, group A) to a parallel period (2019-2020, group B), and a 9-year period preceding the pandemic (March 2011-February 2020, group C). RESULTS: We performed 97 laparoscopies in group A, 82 in group B, and 635 in group C. The proportion of women presenting following in vitro fertilization treatment was lower (odds ratio [OR] 0.22, 95% confidence interval ]95%CI] (0.06-0.86), P < 0.023). Time from admission to decision to operate was shorter (2.7 vs. 3.9 hours, P = 0.028) in group A than group B. Time from admission to surgery was shorter (9.1 vs. 12.5 hours, P = 0.005) and the rate of surgically confirmed AT was lower (59 [60.8%] vs. 455 [71.7%], P = 0.030, OR 0.61, 95%CI 0.39-0.95) in group A than group C. Among surgically confirmed AT cases only, mean time from admission to decision was shorter in group A than group B (2.6 vs. 4.6 hours, P = 0.014). CONCLUSIONS: We identified differences in time from admission to clinical decision and from admission to surgery among women with suspected AT during the COVID-19 pandemic.

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.

Laparoscopic nerve lysis for deep endometriosis improves quality of life and chronic pain levels: A pilot study.

OBJECTIVES: To assess the benefit of surgical management of patients with endometriosis infiltrating pelvic nerves in terms of pain, analgesic consumption, and quality of life (QOL). METHODS: We conducted a retrospective cohort study In an Endometriosis referral center at a tertiary care university affiliated medical center. Patients diagnosed with endometriosis that underwent laparoscopic neurolysis for chronic pain were included. Patients rated their pain before and after surgery and differentiated between chronic pain and acute crises. Patients were requested to maintain a record of analgesic consumption and to evaluate their quality-of-life (QOL). RESULTS: Of the 21 patients in our study 15 (71.5 %) had obturator nerve involvement, 2 (9.5 %) had pudendal nerve involvement and 4 (19 %) had other pelvic nerve involvement. Median postoperative follow - up was of 8 months. All but 2 patients (9.6 %) had significant chronic pain improvement with a mean decrease of VAS of 3.05 (±2.5). Analgesic habits changed postoperatively with a significant decrease of 66 % of patients' daily consumption of any analgesics. Surgery improved QOL in 12 cases (57.1 %) and two patients (9.6 %) completely recovered with a high QOL. CONCLUSION: Neurolysis and excision of endometriosis of pelvic nerves could results in significant improvement of quality of life.

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.

Findings on emergent magnetic resonance imaging in pregnant patients with suspected appendicitis: A single center perspective.

This study's aim is to describe the imaging findings in pregnant patients undergoing emergent MRI for suspected acute appendicitis, and the various alternative diagnoses seen on those MRI scans. This is a single center retrospective analysis in which we assessed the imaging, clinical and pathological data for all consecutive pregnant patients who underwent emergent MRI for suspected acute appendicitis between April 2013 and June 2021. Out of 167 patients, 35 patients (20.9%) were diagnosed with acute appendicitis on MRI. Thirty patients (18%) were diagnosed with an alternative diagnosis on MRI: 17/30 (56.7%) patients had a gynecological source of abdominal pain (e.g. ectopic pregnancy, red degeneration of a leiomyoma); 8 patients (26.7%) had urological findings such as pyelonephritis; and 6 patients (20%) had gastrointestinal diagnoses (e.g. abdominal wall hernia or inflammatory bowel disease). Our conclusions are that MRI is a good diagnostic tool in the pregnant patient, not only in diagnosing acute appendicitis, but also in providing information on alternative diagnoses to acute abdominal pain. Our findings show the various differential diagnoses on emergent MRI in pregnant patients with suspected acute appendicitis, which may assist clinicians and radiologists is patient assessment and imaging utilization.

Clinical implications of a cesarean scar pregnancy sonographic evaluation and reporting system.

OBJECTIVES: Recently, a new standardized sonographic evaluation system for cesarean scar pregnancies (CSP) was published. We aimed to evaluate the clinical outcomes of CSP cases according to the new sonographic evaluation and reporting system. STUDY DESIGN: A retrospective study conducted at a single tertiary center. All CSPs between 1/2011 and 4/2022 were included. Cases were evaluated by expert sonographers and classified into three categories: 1) CSP in which the largest part of the gestational sac (GS) protrudes towards the uterine cavity; 2) CSP in which the largest part of the GS is embedded in the myometrium but does not cross the serosal contour; and 3) CSP in which the GS is partially located beyond the outer contour of the cervix or uterus.Baseline characteristics, management and outcomes were compared between the three categories. RESULTS: Overall, 55 patients were diagnosed with CSP during the study period; 10 (18.1 %) type 1, 31 (56.3 %) type 2, and 14 (25.4 %) type 3. Baseline characteristics were similar among groups. Compared with type 2 and 3, patients diagnosed with CSP type 1 received less methotrexate treatment [83.9 % and 78.6 % vs. 40.0 %, respectively, p = 0.020]. The rates of need for invasive procedures, urgent procedures, major bleeding, length of hospitalization, and subsequent pregnancies were similar between groups. CONCLUSIONS: No clinically significant differences were found between groups divided by the new standardized sonographic evaluation and reporting system for CSP in pregnancy characteristics, management, and subsequent pregnancy outcomes. Further investigation is required to enable informed management of CSP based on the new sonographic reporting system.

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.

Endometrioma increases the risk of antibiotic treatment failure and surgical intervention in patients with pelvic inflammatory disease.

OBJECTIVE: To evaluate the outcome of pelvic inflammatory disease (PID) in patients with endometriosis with and without ovarian endometrioma. DESIGN: A retrospective cohort study. SETTING: A single university-affiliated tertiary center. PATIENT(S): A total of 116 patients with endometriosis hospitalized because of PID between the years 2011-2021. Fifty-nine patients with an ovarian endometrioma component were compared with 57 patients with endometriosis without endometrioma. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The primary outcome was severe PID defined as the need for surgical intervention or drainage. Secondary outcomes included tubo-ovarian abscess, number of hospitalization days, a positive cervical bacterial culture or urine sexually trasmitted disease polymerase chain reaction (STD PCR) test, and readmission because of partially treated or relapsing PID. RESULT(S): PID in patients with endometrioma was found less likely to respond to antibiotic treatment with increased risk for surgical intervention or drainage compared with endometriosis patients without endometrioma (adjusted odds ratio, 3.5; confidence interval, 1.25-9.87). On admission, patients with endometrioma were older (26.5 vs. 31.0) and less likely to have an intrauterine device (19.3% vs. 5.1%) compared with patients without endometrioma. The rate of the tubo-ovarian abscess (52.5% vs. 19.3%) was significantly higher in patients with endometrioma. Readmission rate, positive bacterial culture, and hospitalization duration were higher in the endometrioma group; however, they did not reach statistical significance. Recent oocyte retrieval and patient's age were not associated with an increased risk of severe PID. CONCLUSION(S): Endometrioma patients with PID are less likely to respond to antibiotic treatment and present a higher risk for surgical intervention.

Single-dose methotrexate-based protocol for the treatment of caesarean scar pregnancy and successive pregnancy outcomes.

The incidence of caesarean scar pregnancy (CSP) increases in recent years. Yet, the best mode of treatment and its effects on successive pregnancies is not well established. The aim of this study was to investigate the success rate of single-dose methotrexate (MTX) in the management of CSP, and the outcomes of subsequent pregnancies in a retrospective cohort study. All women who were treated for CSPs between the years 2011 and 2019 were included. Treatment included systemic MTX and ultrasound-guided needle aspiration (UGNA) in cases with active foetal heartbeat. Overall, 34 women were diagnosed with CSP, of whom 31 were treated with systemic MTX. Twelve patients (38.7%) needed additional curettage or hysteroscopy. The only identified risk factor for failure of MTX-based treatment was time interval between the previous caesarean delivery and CSP (22 vs 34 months, p = 0.04). Twelve women had a subsequent pregnancy. Five pregnancies ended in term delivery, three in preterm delivery, three in abortion and one woman had a recurrent CSP. The study conclusion is that a single dose MTX with UGNA in cases of active heartbeat is an effective mode of treatment in cases of CSP with good sequential pregnancy outcomes. Longer time interval from the previous caesarean delivery was identified as a risk factor for failure of conservative management.

Pregnancy-Associated Ovarian Torsion - a Single-Center Case-Control Study.

The etiology of OT is largely unknown. Any predisposition to rotation of the infundibulopelvic ligament and utero-ovarian ligament should be considered a possible etiology. Information with respect to ovarian torsion (OT) among pregnant is underreported and based on small studies. We aim to compare characteristics of confirmed OT to laparoscopies performed for the indication of suspected OT, in which no OT was found among pregnant women. This is a retrospective case-control study. We included pregnant women who underwent laparoscopy for a suspected OT between March 2011 and August 2020. Pregnant women with confirmed OT (torsion group) were compared to those without (no torsion group). There were 169 women with suspected OT. OT was confirmed in 140 (82.8%) women. There was higher proportion of assisted reproductive technology (ART) gestation in the torsion group [76 (54.3%) vs. 5 (17.2%), p < 0.001]. The rate of pregnant approaching evaluation within 8 h of symptoms onset was higher in the torsion group [57 (40.7%) vs. 2 (6.9%), p < 0.001]. The mean visual analogue score (VAS) was higher in the torsion group (8.5 vs. 7.1, p = 0.002). The mean pulse was lower in the torsion group (79 vs. 88 bpm, p < 0.001). From sonographic characteristics examined, the following was higher in the torsion group; mean maximal size of the ovary (70 mm in the torsion group vs. 54 mm in the no torsion group, p = 0.011). In a multivariable logistic regression analysis, number of hours of symptoms was negatively associated with AT [aOR, 95% CI 0.95 (0.91-0.98)] and pulse was negatively associated with OT [aOR, 95% CI 0.78 (0.63-0.95)]. Among the 29 cases in which no OT was found during laparoscopy, the following findings were noted: 16 (55.2%) no abnormality at all, 5 (17.2%) functional ovarian cyst, 2 (6.9%) mature teratoma and 6 cases of peritoneal adhesions (20.7%). The time from pain onset to approaching evaluation and women's pulse should be considered and acknowledged in the evaluation of OT during pregnancy.

Fertility preservation for women with ovarian endometriosis: results from a retrospective cohort study.

RESEARCH QUESTION: What is the outcome of fertility-preservation treatments in women with endometrioma, especially those with endometrioma larger than 4 cm? DESIGN: Retrospective cohort study. Women with definitive diagnosis of ovarian endometriosis (by histology or ultrasound), who underwent fertility-preservation treatment in two IVF units between 2016 and 2021, were included. As some women cryopreserved oocytes and other embryos, the primary outcome was the number of metaphase II (MII) oocytes retrieved. RESULTS: Seventy-one women with ovarian endometriosis (OMA) underwent 138 fertility-preservation cycles. The median age of patients was 31 years. Forty out of 71 (56%) women underwent at least one surgery for OMA before fertility-preservation treatment. Multivariate analysis of each patient's first cycle was used. Women who underwent OMA surgery before fertility-preservation treatment had a 51.7% reduction (95% CI 26.1 to 68.5, P = 0.001) in the number of MII oocytes compared with women with OMA who did not undergo surgery. Among a subgroup who did not undergo surgery, those with an endometrioma larger than 4 cm had similar anti-Müllerian hormone concentration (2.6 ng/ml versus 2.1 ng/ml), number of oocytes retrieved (9 versus 9) and number of MII oocytes (7.6 versus seven 7) compared with women with an endometrioma of 4 cm or less. CONCLUSIONS: Discussing fertility-preservation treatment options with patients with OMA is recommended, especially if surgery is planned.

The effect of endometriosis on placental histopathology and perinatal outcome in singleton live births resulting from IVF.

RESEARCH QUESTION: Does endometriosis have an effect on the placental histopathology pattern and perinatal outcome in singleton live births resulting from IVF treatment? DESIGN: Retrospective cohort study evaluating the data on all live births following IVF treatment between 2009 and 2017 at one university-affiliated tertiary hospital. All patients had placentas sent for full gross and histopathology assessment, irrespective of complication status or delivery mode. The primary outcomes of the study included anatomical, inflammation, vascular malperfusion and villous maturation placental disorders. The secondary outcomes included fetal, maternal, perinatal and delivery complications. A multivariate logistic model was used to adjust the results for confounding factors potentially associated with significant placental characteristics. RESULTS: A total of 1057 live births were included in the final analysis and were allocated to the group of women with endometriosis (n = 75) and those without (n = 982). After adjustment for confounding factors, endometriosis was found to be significantly associated with acute chorioamnionitis with moderate to severe maternal (odds ratio [OR] 2.2, 95% confidence interval [95% CI] 1.1-4.6) and fetal (OR 4.9, 95% CI 1.8-13.1) inflammatory response, placenta previa (OR 3.1, 95% CI 1.2-7.8), subchorionic fibrin deposition (OR 3.4, 95% CI 1.2-9.1), intervillous thrombosis (OR 3.4, 95% CI 1.5-8.1), and fetal vascular malperfusion (OR 5.1, 95% CI 1.4-18.1), as well as with preterm birth (OR 2.5, 95% CI 1.4-4.7). CONCLUSIONS: Endometriosis has a significant impact on the placental histopathology and is associated with a higher incidence of preterm birth.

Pregnancy following cesarean scar defect (niche) repair: a cohort study.

PURPOSE: The aim of the study is to learn the obstetrical outcome of women after laparoscopic niche repair. METHODS: A retrospective cohort study including all women after laparoscopic niche repair done by a single high-skilled surgeon, from July 2014 to March 2019. Data were collected from women's medical records and a telephone interview was performed to assess further symptoms and attempts to conceive, including pregnancy outcomes. RESULTS: During the study period, 48 women underwent laparoscopic niche repair, of them complete follow-up was achieved for 37 (78.7%) women. The median residual myometrial thickness measured by ultrasound before the repair was 2.0 mm (IQR 1.4-2.5). Attempts to conceive were reported by 81% (n = 30) of the women, while 18 (60%) achieved pregnancy in median time of 6 month (IQR 5-12) post-niche repair. 14 (78%) of the women conceived spontaneously. No placental abnormalities were reported in any of the women. All gave birth by cesarean delivery at a median of 38.4 gestation week (IQR 37.0-39.5). No dehiscence or rupture was reported. CONCLUSIONS: Pregnancy following niche repair can be achieved with low pregnancy complication rate and good pregnancy outcomes. Further studies need to be done to strengthen our findings.

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.
