Study Objective: Most cases of adnexal torsion in pregnancy are currently managed by laparoscopy, which may be associated with increased risks for spontaneous abortion and preterm delivery. We sought to evaluate the obstetric outcomes of these women, with emphasis on their live birth rate and gestational age at delivery., Design: Retrospective cohort study and telephone questionnaire., Setting: University-affiliated obstetrics and gynecology department., Patients: All pregnant women who underwent laparoscopy for adnexal torsion between 2007 and 2017. Their obstetric outcomes were obtained by retrospective review of medical records and a telephone questionnaire., Interventions: Laparoscopy for adnexal detorsion, with or without cyst drainage or cystectomy., Measurements and Main Results: The study cohort included 94 women. Most torsion cases (71, 75.5%) were diagnosed in the first trimester of pregnancy, whereas 21 (22.3%) cases and 2 (2.1%) cases were diagnosed in the second and third trimesters, respectively. Conception was achieved by in vitro fertilization or by ovulation induction in 45 (47.9%) cases. The information on pregnancy outcomes was available for 93 women. Of those, live birth was reported for 86 (92.5%) pregnancies, while 6 (6.5%) women had a spontaneous abortion, and 1 woman experienced an intrauterine fetal death. Five cases of spontaneous abortion were diagnosed in the first trimester, all within 3 weeks of surgery. Preterm delivery before 37 gestational weeks was reported for 18 (19.4%) pregnancies and was significantly associated with twin pregnancy (p = .002) and with conception following in vitro fertilization and ovulation induction (p = .03). On logistic regression analysis, preterm delivery was only associated with twin vs singleton gestation (odds ratio, 6.7; 95% confidence interval, 1.3-34.8; p = .02)., Conclusion: The obstetric outcomes of pregnant women who underwent laparoscopy for adnexal torsion are generally favorable. However, there is a risk for preterm delivery, which is primarily associated with multiple gestations., (Copyright © 2019 AAGL. Published by Elsevier Inc. All rights reserved.)

Purpose: The aim of this study was to investigate the association of clinical, laboratory and ultrasound findings with the surgical diagnosis of adnexal torsion in a retrospective cohort of women operated for suspected torsion., Methods: The study included 199 reproductive age women > 16-year-old who underwent urgent laparoscopy for suspected adnexal torsion between January 2008 and December 2014. The association of various parameters with adnexal torsion was analyzed with a multivariate logistic regression analysis and described as odds ratios (OR) ± 95% confidence intervals (CI)., Results: Adnexal torsion was surgically diagnosed in 111/199 (55.8%) cases. On the multivariate logistic regression analysis, complaints of nausea/vomiting (OR 4.5, 95% CI 1.8-11.1), peritoneal irritation signs (OR 100.9, 95% CI 4.2-2421.9), elevated white blood cell count > 11,000 cells/mL (OR 3.7, 95% CI 1.3-10.8), presence of free pelvic fluid on ultrasound (OR 34.4, 95% CI 6.7-177.9), ultrasound findings suggestive of ovarian edema (OR 4.2, 95% CI 1.5-11.6), ultrasound findings suggestive of benign cystic teratoma (OR 7.8. 95% CI 1.2-49.4) and location of the ultrasound pathology on the right side (OR 4.7. 95% CI 1.9-11.9) were positively associated with adnexal torsion, while ultrasound findings suggestive of hemorrhagic corpus luteum cyst (OR 0.04, 95% CI 0.008-0.2) were negatively associated with adnexal torsion. By combining these eight parameters, the ROC curve was calculated, yielding an area under the curve of 0.93, 95% CI 0.90-0.97 (p < 0.0001)., Conclusion: Routine clinical, laboratory and grayscale ultrasound findings may be incorporated into the emergency room workup of women with suspected adnexal torsion. Laparoscopy should be considered in all patients with suspected adnexal torsion.

Objective: To compare adnexal torsion characteristics and torsion recurrence rates in a pre- and postmenarchal pediatric and adolescent population., Design: Retrospective cohort study., Setting: University-affiliated medical center., Patient(s): Females <18 years old with surgically diagnosed adnexal torsion., Intervention(s): Adnexal detorsion, cystectomy, salpingectomy, or salpingo-oophorectomy by laparoscopy or laparotomy. Oophoropexy using the utero-ovarian ligament plication technique was performed in cases of recurrent torsion of normal adnexa., Main Outcome Measure(s): The clinical presentation, laboratory and ultrasound characteristics, surgical findings, surgical procedures, pathologic diagnosis, and torsion recurrence rates were analyzed and compared between pre- and postmenarchal patients., Result(s): Twenty premenarchal and 24 postmenarchal patients were identified. The clinical presentation, laboratory findings, and ultrasound characteristics were similar between the two groups, except for a higher prevalence of paraovarian cysts on preoperative ultrasound in the postmenarchal compared with in the premenarchal group (20.8% vs. 0%). For the whole cohort, torsion of normal adnexa constituted 25.0% (11/44) of cases, while torsion of "pathologic" adnexa constituted 75.0% (33/44) of torsion cases. Torsion recurrence was significantly more common among girls whose first torsion episode occurred in the premenarchal period compared with in postmenarche (35% vs. 4.2%). On multivariate logistic regression analysis, torsion recurrence was significantly associated with premenarchal status (odds ratio [OR] = 12.7; 95% confidence interval [CI], 1.1-152.0) and with torsion involving normal adnexa (OR = 19.1; 95% CI, 2.3-154.5)., Conclusion(s): Recurrent torsion is common in patients whose first torsion episode occurred in the premenarchal period and involved otherwise normal adnexa. Ovarian fixation procedures may be considered in patients at risk for torsion recurrence., (Copyright © 2016 American Society for Reproductive Medicine. Published by Elsevier Inc.

Background: We sought to investigate and compare the clinical presentation, ultrasound findings, surgical characteristics, and causes of adnexal torsion among three groups: pediatric and adolescent population, reproductive-age women, and pregnant women., Material and Methods: Two hundred twenty-seven surgically confirmed episodes of adnexal torsion in 199 patients treated in our department from January 2008 to December 2014 were retrospectively analyzed., Results: Abdominal pain duration of >24 hours before emergency room presentation was more common in pediatric and adolescent patients compared with reproductive-age and pregnant women (42.3% vs. 28.4% and 15.5%, respectively, p = 0.04). However, there was no difference between the groups in the time interval from their emergency room admission to surgery. Torsion of "normal adnexa" occurred in 11/44 (25.0%) of pediatric and adolescent patients, 30/99 (30.3%) of reproductive-age patients, and 12/56 (21.4%) of pregnant patients, while torsion involving multicystic ovaries occurred in 0%, 4%, and 32.1%, respectively, torsion involving paraovarian cysts occurred in 20.5%, 14.1%, and 1.8%, respectively, and torsion involving benign dermoid cysts occurred in 4.5%, 15.2%, and 5.4%, respectively (p < 0.001). Torsion involving supposedly functional ovarian cysts occurred in 45.5%, 34.3%, and 69.6%, respectively (p < 0.001). The torsion recurrence rates were 18.2% in the pediatric subjects, 19.2% in reproductive-age women, and 10.7% in pregnant women (p = 0.3)., Conclusions: The presentation of adnexal torsion is similar in pediatric and reproductive-age and pregnant women, although the underlying adnexal pathology may be different. Functional ovarian cysts cause the majority of torsion cases in pregnant women. Recurrence of torsion may occur in any age group.

Objective: Torsion of normal adnexa is a rare event involving steadily increasing congestion and ischemia of the ovary. We investigated whether this process can be characterized by sonographic features., Methods: Twelve menstrually cycling women with 14 separate episodes of laparoscopic-proven torsion of normal adnexa were identified retrospectively, and the results of their preoperative gray-scale ultrasound examinations and Doppler flow evaluations were analyzed. The cases were classified into 'short-term' (< 24 h; range, 3-24 h) and 'prolonged' (> 24 h; range, 1-10 days) duration of torsion according to the reported period of abdominal pain before admission. Absence of any additional adnexal pathology was confirmed by both intraoperative inspection and postoperative follow-up ultrasound examinations., Results: The median age of the cohort was 24.0 (interquartile range (IQR), 20.5-28.7) years, and parity ranged from 0 to 3. All affected ovaries were significantly enlarged compared with non-affected ones (median cross-sectional area, 18.1 (IQR, 12.4-26.4) cm(2) vs. 4.3 (IQR, 2.9-6.2) cm(2), P < 0.01). We could distinguish two distinct sonographic patterns of torted ovaries: there were numerous small peripheral follicles in the ovarian parenchyma in nine cases, and there was a solid-appearing mass with hypo- and hyperechogenic foci in five cases. Comparison of the ultrasound images of patients with short-term vs. long-term abdominal pain revealed that the solid-appearing ovary was more common in the latter group (0/6 vs. 5/8, P = 0.03), while there was no significant difference between groups in the presence of free pelvic fluid or median ovarian cross-sectional area. Intraovarian blood flow was diminished or absent in five of the eight patients in whom color Doppler imaging was performed., Conclusions: Ultrasound images of twisted normal adnexa may vary according to the duration of the condition, reflecting the pathological series of events of increased ovarian congestion and necrosis. Recognition of the different sonographic features of twisted normal adnexa may assist in the correct diagnosis of these patients., ((c) 2008 ISUOG. Published by John Wiley & Sons, Ltd.)
