Recurrence following perineal proctosigmoidectomy with levatorplasty: Review and meta-analyses

•Recurrence rates for full-thickness rectal prolapse following proctosigmoidectomy with levatorplasty occur at an average of 13.8%.•Addition of levatorplasty does not significantly reduce recurrence rates.•Levatorplasty may provide improvement in functional outcomes such as obstructive defecation and fecal incontinence. Full-thickness rectal prolapse remains a challenging pathology to correct surgically with significant recurrence rates. Among perineal approaches, the proctosigmoidectomy with levatorplasty, commonly referred to as the Altemeier procedure is frequently performed. The addition of levatorplasty has been postulated to improve recurrence rates, however, its efficacy varies across studies. The aim of this study was to systematically review recurrence rates following proctosigmoidectomy with levatorplasty, and to meta-analyze pooled data comparing recurrence rates between proctosigmoidectomy with and without a levatorplasty. A search of EMBASE, OVID Medline, and CENTRAL was performed from database inception to October 2021 aimed at identifying studies investigating recurrences of rectal prolapse following proctosigmoidectomy with levatorplasty. Primary endpoint was recurrence of rectal prolapse. Articles that did not report this endpoint or did not evaluate proctosigmoidectomy with levatorplasty were excluded. A pairwise meta-analysis was performed using Mantel-Haenszel random effects. From 200 citations, 14 primary studies met inclusion criteria. A total of 620 patients (88.9% female, mean age: 71 years) underwent proctosigmoidectomy with levatorplasty, and 117 without levatorplasty. Of the patients undergoing levatorplasty, 86 (13.8%) experienced a recurrence. Mean follow up was 46 months. Meta-analysis comparing recurrence rates between proctosigmoidectomy with and without levatorplasty demonstrated no significant difference (RR 0.80, 0.92, 95% CI 0.32–2.59, P = 0.87, I2 = 77%). Narrative review of postoperative quality of life metrics demonstrated decreased incontinence with levatorplasty as measured by Wexner and ICIQ-SIF scores. The addition of a levatorplasty does not significantly reduce the risk of recurrent rectal prolapse after proctosigmoidectomy, however it may improve postoperative continence.
