Perineal stapled prolapse resection for external rectal prolapse: a systematic review and meta-analysis.

Abstract

Rectal prolapse is an uncommon but debilitating pelvic floor disorder that significantly decreases the quality of life of affected patients. Perineal stapled prolapse resection is a relatively new perineal approach that offers an promising alternative technique in the surgical management of rectal prolapse. It appears to be a simple, reproducible and efficient method. However, long-term outcomes are limited. The aims of this review are to assess the safety and effectiveness of perineal stapled prolapse resection in the management of rectal prolapse. A systematic review of all articles describing this approach was searched using MEDLINE, Embase, PubMed, Cochrane, Scopus, Web of Science and China National Knowledge Infrastructure. Included in this review were all randomized and nonrandomized prospective and retrospective studies reporting patients (aged 16years and older) with complete rectal prolapse who underwent perineal stapled prolapse resection for the surgical treatment of the rectal prolapse. A total of 408 patients across 20 articles were included. There were 58 cases of recurrence out of 368 patients over a median length of follow-up of 18 months (interquartile range 12-34months). The total weighted overall recurrence was 12%. There were 51 cases of postoperative complications in 350 cases, bleeding being the most common complication. The recurrence rate is comparable to those of the well-established Altemeier and Delorme procedures. However, given the heterogeneity of studies and variations in lengths of follow-up, further randomized prospective studies are needed to adequately compare this technique against other procedures for complete rectal prolapse.
