Abstract

Study Objective: To investigate the pregnancy and neonatal outcomes of surgical treatment for adnexal torsion (AT) during pregnancy. Design: A retrospective case-control study (Canadian Task Force classification II-2). Setting: A tertiary care academic medical center. Measurements and Main Results: The study group included all parturients who underwent surgery for suspected AT during pregnancy from January 2005 to January 2017. The control group included parturients with an uneventful pregnancy matched by maternal age, parity, multiple gestation, and pregnancy complications. The primary outcome was gestational age at delivery. Secondary outcomes were perinatal outcomes and intraoperative and immediate postoperative complications. Among 85 study group patients with suspected AT, 78 (91.7%) underwent laparoscopy and 7 (8.3%) laparotomy. Torsion was diagnosed in 84 patients (98.8%). The gestational age at delivery was similar between the study and control groups (38.7 ± 1.5 vs 38.6 ± 1.6 weeks, respectively; p =.908) as was preterm labor (5.8% in both groups, p = 1.00). There was no significant difference between the study and control groups in pregnancy and neonatal outcomes, including Apgar scores, mean cord blood pH (7.25 ± 0.1 and 7.26 ± 0.08, respectively), and birth weight (3040 ± 473 g and 3115 ± 584 g, respectively). In the study group, the mean gestational age at surgery was 11.2 ± 6 weeks (range, 4–34 weeks). The average operative time was 40.2 ± 22 minutes. In the postoperative follow-up, 3 (3.5%) patients had a first trimester miscarriage. A previous cesarean delivery was a risk factor for ovarian torsion during pregnancy (p =.012). Conclusion: Adnexal detorsion with or without additional surgical procedures during pregnancy did not affect the gestational age at delivery and did not appear to increase fetal or maternal complication rates.
