Vaginal Cuff Self-Suspension Technique: A Novel Apical Suspension Technique for Patients With Uterovaginal Prolapse and Poor Tissue Integrity [ID 2683606

Abstract

INTRODUCTION: Of all surgical approaches to correct apical prolapse, transvaginal native tissue repair (TNTR) accounts for 80–90% of cases. Conditions such as uncontrolled diabetes lead to poor tissue integrity, often rendering the anatomical structures necessary insufficient, resulting in recurrent prolapse or immediate procedure failure. We present a novel TNTR technique, called “vaginal cuff self-suspension technique” (VCST) that can be used in such cases to provide a potentially more reliable and efficient means of apical suspension. METHODS: We conducted a prospective observational study from July 2022 to July 2023 and followed all patients who underwent a total hysterectomy and subsequent TNTR for advanced uterovaginal prolapse and concurrent stage IV endometriosis or uncontrolled diabetes. Advanced uterovaginal prolapse was defined as either a POP-Q score of 3 or 4 or Baden-Walker Grade 3 or 4. Patients receiving VCST were compared with matched controls receiving other TNTR methods. The primary outcomes were recurrent apical prolapse at 6 months or failure at initial surgery, as discrete events. All appropriate IRB approvals were obtained. RESULTS: The study included 88 patients with 33 receiving VCST and 55 controls. Of the 55 controls, 42 utilized uterosacral ligament suspensions (USLS) and 13 utilized sacrospinous ligament fixations. Demographic factors were not significantly different. Patients receiving VCST had lower rates of initial failed suspension (6% versus 23%; P=.002) as well as a 37% decreased risk in confounder-adjusted models (risk ratio [RR] 0.63; 95% CI, 0.36–0.81; P=.003). Among patients with poorly controlled diabetes, the VCST had lower rates of recurrent prolapse (9% versus 47%) and a 81% decreased risk in confounder-adjusted models (RR 0.19; 95% CI, 0.08–0.31; P<.001). CONCLUSION: Vaginal cuff self-suspension technique offers a simple and effective way to potentially prevent recurrent apical prolapse and/or immediate procedure failure for patients with advanced uterovaginal prolapse and concurrent stage IV endometriosis or poorly controlled diabetes.
