Effectiveness of Prophylactic Laparoscopic Surgery for Benign Adnexal Mass during Pregnancy: A Single-center Retrospective Study.

Abstract

This study aimed to evaluate the effectiveness of prophylactic laparoscopic surgery for avoiding adnexal torsion in pregnant women with benign adnexal masses. This report contains two analyses, each for a different group of patients. Analysis 1: Surgical and pregnancy outcomes were examined among the 126 cases who underwent laparoscopic assisted cystectomy for adnexal masses during pregnancy in our hospital between January 2001 and December 2020. Analysis 2: The incidence of adnexal torsion during pregnancy was evaluated among the cases with adnexal masses ≥5 cm who opted for conservative follow-up in our hospital between January 2011 and December 2020. In analysis 1, the most common pathological diagnosis was a mature cystic teratoma (76.2%). The mean gestational age at surgery was 13.1 ± 1.3 weeks. No cases were converted to laparotomy and oophorectomy. Regarding delivery outcomes, 97.4% of cases went on to have full-term deliveries. In Analysis 2, the incidence of adnexal mass ≥5 cm that did not resolve spontaneously during pregnancy was 89 cases (0.8%). The frequency of malignancy was 3 cases (0.03%). In 28 cases who opted for conservative treatment, 5 (17.9%) underwent emergency surgery for adnexal torsion. Prophylactic surgery for benign adnexal masses during pregnancy can be performed laparoscopically and preserved ovarian functions. In pregnant women with adnexal masses that do not resolve spontaneously, planning laparoscopic surgery is considered beneficial for complications, such as adnexal torsion.
