摘要

Background: No randomized controlled trial has compared no rectopexy with rectopexy for external full-thickness rectal prolapse. Objective: This study was performed to test the hypothesis that recurrence rates following no rectopexy are not inferior to those following rectopexy for full-thickness rectal prolapse. Design: This was a multicenter randomized controlled trial. Eligible patients were randomly assigned to no rectopexy or rectopexy. The end point was recurrence rates defined as the presence of external full-thickness rectal prolapse after surgery. A prerandomized controlled trial meta-analysis suggested a sample size of 251 patients based on a 15% expected difference in the 5-year cumulative recurrence rate. Recurrence-free curves were generated and compared using the Kaplan-Meier method and log-rank test, respectively. Data were presented as median (range).
