Hiatal hernia, mitral valve prolapse and defecatory disorders: An underlying rectal prolapse?

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

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.

Perineal resectional procedures for the treatment of complete rectal prolapse: A systematic review of the literature

BACKGROUND AND AIM

Several procedures for the treatment of complete rectal prolapse (CRP) exist. These procedures are performed via the abdominal or perineal approach. Perineal procedures for rectal prolapse involve either resection or suspension and fixation of the rectum. The present review aimed to assess the outcomes of the perineal resectional procedures including Altemeier procedure (AP), Delorme procedure (DP), and perineal stapled prolapse resection (PSR) in the treatment of CRP.

PATIENTS AND METHODS

A systematic search of the current literature for the outcomes of perineal resectional procedures for CRP was conducted. Databases queried included PubMed/MEDLINE, SCOPUS, and Cochrane library. The main outcomes of the review were the rates of recurrence of CRP, improvement in bowel function, and complications.

RESULTS

Thirty-nine studies involving 2647 (2390 females) patients were included in the review. The mean age of patients was 69.1 years. Recurrence of CRP occurred in 16.6% of patients. The median incidences of recurrence were 11.4% for AP, 14.4% for DP, and 13.9% for PSR. Improvement in fecal incontinence occurred in 61.4% of patients after AP, 69% after DP, and 23.5% after PSR. Complications occurred in 13.2% of patients. The median complication rates after AP, DP and PSR were 11.1%, 8.7%, and 11.7%, respectively.

CONCLUSION

Perineal resectional procedures were followed by a relatively high incidence of recurrence, yet an acceptably low complication rate. Definitive conclusions on the superiority of any procedure cannot be reached due to the significant heterogeneity of the studies.
