Comparison of transvaginal natural orifice transluminal endoscopic surgery versus conventional surgery for uterosacral ligament suspension in patients who had concomitant vaginal hysterectomy for subtotal uterine prolapse.

Introduction: The study aimed to compare the short-term outcomes of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) for uterosacral ligament suspension (USLS) versus nonendoscopic USLS in patients with subtotal uterine prolapse who had a concomitant vaginal hysterectomy.

Methods: There were 51 patients who underwent vNOTES USLS, whereas the nonendoscopic conventional USLS group had 49 patients. The information about patient demographics, and perioperative data including the operative duration, blood loss, intraoperative and postoperative complications, and length of postoperative hospital stay were determined from the patients' files. Postoperative follow-up visits were scheduled at the first week and 1 month after surgery.

Results: The demographic variables including age, body mass index, menopausal status, and parity were comparable, and no significant differences were found. A total of 90.2% of the patients in the vNOTES group and 69.4% of the patients in the shull group were at menopause (p = .09). Operation time was significantly shorter in the shull group (p < .001), and the hospitalization period (p = .029) was significantly shorter in the vNOTES group. Ba, Bp, and D points and total vaginal length (TVL) were significantly behind the hymenal ring in patients who had vNOTES USLS procedure (p < .001). None of the patients who had intraoperative significant blood loss required transfusion. One patient in the vNOTES and two patients in the shull group had a postoperative cuff hematoma.

Conclusion: vNOTES USLS has a good safety profile, higher percentage of adnexal surgeries with better improvement on POP-Q points Ba, Bp, D, and TVL compared with classic USLS in patients with subtotal uterine prolapse. Studies evaluating short- and long-term results of vNOTES versus conventional USLS are needed.
