Ovarian preservation and prognosis in adnexal torsion surgery — a retrospective analysis

Objectives: This study aims to analyze the conditions of ovarian preservation during adnexal torsion surgery, and safety of ovarian preservation. Material and methods: A retrospective analysis of 130 patients, who underwent surgery for ovarian benign tumor pedicle torsion in Fujian Provincial Maternal and Child Health Hospital from June 2013 to June 2018, was conducted. This study analyses the possible risk factors affecting the operation method using multiple logistic regression and analyses the complications and the recovery of ovarian function after the treatment of the ovarian preservation. Results: Among these patients, 58 received ovarian cystectomy, while 72 received ovariectomy. There was no significant difference in terms of age, preoperative blood, operation time and surgical bleeding volume between the two groups (p > 0.05). However, there was a significant difference in preoperative adnexal blood flow, abdominal pain to the surgical interval, and a collection of torsion cycles (p < 0.05). There was an increased risk of ovarian resection in patients whose blood flow of the annex disappeared, whose time of abdominal pain was long, and whose number of twists were significant. For the preservation group, there were no increases in postoperative complications. Conclusions: According to clinical indicators, such as preoperative adnexal blood flow, abdominal pain to the interval of surgery and the number of torsion cycles, it was determined whether it was feasible to keep the ovary. Retaining the ovary is safe, effective and feasible in adnexal torsion.
