Laparotomy versus laparoscopy for the treatment of adnexal torsion during pregnancy.

Background: Adnexal torsion (AT) is a rare emergency complication during pregnancy. Increasing evidence implies that operative laparoscopy for adnexal torsion performed during pregnancy could be safe and feasible. We procured and evaluated the surgical and obstetric outcomes between laparoscopy and laparotomy to determine the optimal approach for treating AT during pregnancy.

Methods: This was a retrospective study involving telephone questionnaire on adnexal torsion during pregnancy that occurred between July 2012 and July 2023 in the First Affiliated Hospital of Zhengzhou University. The study cohort included 155 pregnant women who underwent laparotomy or laparoscopic surgery. The clinical characteristics, surgical interventions, postoperative pathology and pregnancy outcomes were analyzed.

Results: A total of 102 patients were treated by laparoscopy, and 53 patients were treated by laparotomy. Compared with the laparotomy group, the laparoscopy group had significantly less blood loss (17.5 ml vs. 20.0 ml, p = .004), a lower incidence of delayed incision healing (1.0% vs. 11.3%, p = .011), and a shorter hospital stay (5.0 days vs. 8.0 days, p < .001). There was no significant difference between the two groups in terms of obstetric outcomes, including preterm delivery, miscarriage rate, birth weight, delivery gestation, cesarean delivery rate, or neonatal intensive care unit admission. All the pathological findings were benign except for one case of borderline mucinous cystadenoma. The most common pathological types were luteal cysts in the laparoscopy group and mature teratomas in the laparotomy group.

Conclusion: In this retrospective study, compared with laparotomy, laparoscopy yielded successful outcomes, with less surgical bleeding, less delayed wound healing, and shorter hospital stays. Laparoscopy could be a promising approach for diagnosing and treating AT during pregnancy.
