Mesh Exposure Following Vaginal Versus Laparoscopic Hysterectomy at the Time of Sacrocolpopexy.

Abstract

To compare vaginal mesh exposure rates, adverse events and composite failure within 1year postoperatively in patients who undergo vaginal hysterectomy with vaginal mesh attachment (TVH) versus laparoscopic hysterectomy with abdominal mesh attachment (TLH) for minimally invasive sacrocolpopexy. This multicenter retrospective cohort study is a secondary analysis of data collected retrospectively at one institution and the multicenter randomized control PACT trial. Women were excluded for no follow-up between 9months and 2years postoperatively or undergoing concurrent non-urogynecologic procedures. Between 2010 and 2019, 182 patients underwent TLH and 132 TVH. There were 15 (4.8%) vaginal mesh exposures: 12 (6.6%) in the TLH and 3 (2.3%) in the TVH group (p = 0.133) with zero mesh erosions. Logistic regression analysis for mesh exposure in the TLH vs. TVH groups controlling for BMI, posterior repair and surgeon training also showed no significant difference (OR 4.8, 95% CI 0.94, 24.8, p = 0.059). The overall intraoperative complication rate was low (19/314, 6.1%) with a higher rate of bladder injury in the TLH group (4.4% vs. 0.8%, p = 0.049). The TLH group had a higher rate of UTI (8.2% vs. 2.3%, p = 0.027) and clean intermittent catheterization (11% vs. 3%, p = 0.009). At 1-year follow-up, there was no difference in composite failure (6%), bulge symptoms (5%) or retreatment (1%) between groups. At 1 year, there is no significant difference in vaginal mesh exposure rates between vaginal hysterectomy with vaginal mesh attachment and laparoscopic hysterectomy with abdominal mesh attachment. Both groups have equal efficacy with low rates of complications.
