Pregnancy outcomes following laparoscopy for suspected adnexal torsion during pregnancy

Abstract

Objective To evaluate pregnancy outcomes of women with surgically confirmed adnexal torsion (AT) as compared to those in whom AT was ruled out. Methods A retrospective cohort study in a tertiary medical center. All pregnant women who underwent diagnostic laparoscopy due to suspected AT between 3/2011 and 4/2020 were included. We compared maternal, delivery and neonatal outcomes of both groups. We further compared women with confirmed AT to a control group of women who did not undergo laparoscopy during pregnancy. Results During the study period, 112 women met the inclusion criteria. AT was confirmed in 93 cases (83.0%). Baseline characteristics did not differ between groups, excluding the rate of previous AT [5.4% in the torsion vs. 26.3% in the no-torsion group, odds ratio (OR) 0.15, 95% confidence interval (CI) 0.04–0.62, p = .004], and nulliparity rate (57.0% in the torsion vs. 31.6% in the no-torsion group, OR 2.41, 95%CI 1.004–8.21, p = .043). Pregnancies conceived by assisted reproductive technology were more common in the AT group compared to the no-AT group (46.2% vs. 10.5%, OR 7.21, 95%CI 1.59–33.45, p = .002). Miscarriage and stillbirth rates, gestational age at delivery, delivery characteristics and neonatal outcomes were favorable and did not differ between groups. Outcomes of pregnancies with confirmed AT did not differ from a control group of women who did not undergo laparoscopy during pregnancy. Conclusion Pregnancy outcomes among women who underwent laparoscopy for a suspected AT during pregnancy were reassuring, irrespective of the surgical findings and gestational week. Outcomes did not differ when compared to pregnant women who did not undergo laparoscopy. Synopsis Maternal, fetal and neonatal outcomes among women who underwent laparoscopy for suspected adnexal torsion during pregnancy are reassuring, irrespective of the surgical findings and gestational week.
