摘要

Purpose

Rectal prolapse is a known sequela in adults with anorectal malformations (ARMs), presenting unique surgical challenges due to altered pelvic anatomy, prior reconstructions, and compromised bowel function. This study aimed to evaluate the suitability of conventional rectal prolapse repair techniques for this population and to present our institutional outcomes.

Methods

A literature review was conducted to identify standard rectal prolapse repair procedures in adults. In addition, a retrospective review of adult ARM patients undergoing prolapse repair between 2018 and 2023 at a single tertiary center was performed. Data collected included demographics, ARM type, prolapse characteristics, surgical procedures, and outcomes.

Results

Seventeen adult ARM patients (59% female, median age 30 years) underwent prolapse repair. The majority (88%) were treated with a modified Altemeier procedure; 12% underwent a modified Delorme procedure. Rectopexy or rectosigmoid resection were avoided due to altered anatomy and risk to continence mechanisms. At a median follow-up of 18 months, two patients (12%) experienced minor recurrence.

Conclusions

Perineal resections such as modified Delorme or modified Altemeier procedures are effective and safe for adult ARM patients with rectal prolapse. Surgical strategies must be individualized to accommodate the complex anatomy and functional considerations in this population.
