Study Objective: The objective of this study was to compare the morbidity of vaginal versus laparoscopic hysterectomy when performed with uterosacral ligament suspension. Design: Retrospective propensity-score matched cohort study. Setting: American College of Surgeons National Surgical Quality Improvement Program database. Patients: We included all patients who had undergone uterosacral ligament suspension and concurrent total vaginal hysterectomy (TVH-USLS) or total laparoscopic hysterectomy (TLH-USLS) from 2010 to 2015. We excluded those who underwent laparoscopic-assisted vaginal hysterectomy, abdominal hysterectomy, other surgical procedures for apical pelvic organ prolapse, or had gynecologic malignancy. Interventions: We compared 30-day complication rates in patients who underwent TVH-USLS versus TLH-USLS in both the total study population and a propensity score matched cohort. Measurements and Main Results: The study population consisted of 3,349 patients who underwent TVH-USLS and 484 who underwent TLH-USLS. Patients who underwent TVH-USLS had a significantly higher composite complication rate (11.4% vs 6.4%, odds ratio [OR] 1.9, 1.3-2.8; p < .01) and a higher serious complication rate (5.6% vs 3.1%, OR 1.8, 1.1 - 3.1; p = .02), which excluded urinary tract infection and superficial surgical site infection. The propensity score analysis was performed, and patients were matched in a 1:1 ratio between the TVH-USLS group and the TLH-USLS group. In the matched cohort, patients who underwent TVH-USLS had a higher composite complication rate than those who underwent TLH-USLS (10.3% vs 6.4%, OR 1.7, 95% confidence interval [CI], 1.1-2.7; p = .04), whereas the rate of serious complications did not differ between the groups (4.3% vs 3.1%, OR 1.4, 95% CI, 0.7-2.8; p = .4). On multivariate logistic regression, TVH-USLS remained an independent predictor of composite complications (adjusted OR 1.6, 95% CI, 1.0-2.6; p = .04) but not serious complications (adjusted OR 1.4, 95% CI, 0.7- 2.8; p = .3). Conclusion: In this large national cohort, TVH-USLS was associated with a higher composite complication rate than TLH-USLS, largely secondary to an increased rate of urinary tract infection. After matching, the groups had similar rates of serious complications. These data suggest that TLH-USLS should be viewed as a safe alternative to TVH-USLS. (C) 2020 AAGL. All rights reserved.
