Surgery for complete rectal prolapse in adults

Complete rectal prolapse is a life-style altering disability that commonly affects older people. The range of surgical methods available to correct the underlying pelvic floor defects in complete rectal prolapse suggests that there is no agreement about the choice of the best operation. To determine the effects of surgery on the treatment of rectal prolapse in adults. We searched the Cochrane Incontinence Group Specialised Register (searched 10 January 2008), the Cochrane Colorectal Cancer Group Trials Register (searched 10 January 2008), CENTRAL (Issue 1, 2008), PubMed (1 January 1950 to 10 January 2008) and EMBASE (1 January 1998 to 10 January 2008). The British Journal of Surgery (January 1995 to January 2008) and the Diseases of the Colon and Rectum (January 1995 to January 2008) were specifically hand searched. The proceedings of the Association of Coloproctology meetings held from 1999 to 2007 were perused. Reference lists of all relevant articles were searched for further trials. All randomised or quasi-randomised trials of surgery in the management of adult rectal prolapse. Three reviewers independently selected studies from the literature searches, assessed the methodological quality of eligible trials and extracted data. The four primary outcome measures were: number of patients with recurrent rectal prolapse, number of patients with residual mucosal prolapse, and number of patients with faecal incontinence or constipation. Twelve randomised controlled trials including 380 participants were identified and included in this review. One trial compared abdominal with perineal approaches to surgery, three trials compared fixation methods, three trials looked at the effects of lateral ligament division, one trial compared techniques of rectosigmoidectomy, two trials compared laparoscopic with open surgery and two trials compared resection with no resection rectopexy.The heterogeneity of the trial objectives, interventions and outcomes made analysis difficult. Many review objectives were covered by only one or two studies with small numbers of participants. With these caveats in mind there is insufficient data to say which of the abdominal and perineal approaches has a better outcome. There were no detectable differences between the methods used for fixation during rectopexy. Division, rather than preservation, of the lateral ligaments was associated with less recurrent prolapse but more post-operative constipation. Laparoscopic rectopexy was associated
