Outcome of Laparoscopic Ventral Mesh Rectopexy for Full-Thickness External Rectal Prolapse: a Systematic Review, Meta-Analysis, and Meta-Regression Analysis of the Predictors for Recurrence

摘要

Background: Laparoscopic ventral mesh rectopexy (LVMR) has proved effective in the treatment of internal and external rectal prolapse. The present meta-analysis aimed to determine the predictive factors of recurrence of full-thickness external rectal prolapse after LVMR. Methods: An organized, systematic search of electronic databases including PubMed/Medline, Embase, Scopus, and Cochran library was conducted in adherence to PRISMA guidelines. Studies that reported the outcome of LVMR in patients with full-thickness external rectal prolapse were included according to predefined criteria. A meta-regression analysis and sub-group meta-analyses were performed to recognize the patient and technical factors that were associated with higher recurrence rates.
