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.
Results
Seventeen studies comprising 1242 patients of a median age of 60 years were included. The median operation time was 122.3 min. Conversion to open surgery was required in 22 (1.8%) patients. The weighted mean complication rate across the studies was 12.4% (95% CI 8.4–16.4) and the weighted mean rate of recurrence of full-thickness external rectal prolapse was 2.8% (95% CI 1.4–4.3). The median follow-up duration was 23 months. Male gender (SE = 0.018, p = 0.008) and length of the mesh (SE = − 0.007, p = 0.025) were significantly associated with full-thickness recurrence of rectal prolapse. The weighted mean rates of improvement in fecal incontinence and constipation after LVMR were 79.3% and 71%, respectively.
Conclusion
LVMR is an effective and safe option in treatment of full-thickness external rectal prolapse with low recurrence and complication rates. Male patients and length of the mesh may potentially have a significant impact on recurrence of rectal prolapse after LVMR.
