Rectal Prolapse Surgery: Balancing Effectiveness and Safety in Abdominal and Perineal Approaches

Abstract

The event in which the entire thickness of the rectum protrudes through the anal canal is called rectal prolapse. This ailment is common in the elderly population and especially in females. It causes some disastrous symptoms, including incontinence to feces and flatus, constipation, and discomfort, because of the weakness in the anorectal junction, making it mandatory for surgical correction. Over time, several surgical techniques have been developed; these are broadly classified into two categories: abdominal and perineal techniques. However, the best approach for surgery that minimizes recurrence while maximizing patient quality of life is still up for debate. A comprehensive review was conducted adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines; a systematic search of the PubMed Database was performed to identify studies published between 2000 and 2024 with the keywords ((Rectal Prolapse) AND ("Perineal" OR "Laparotomy")). The inclusion criteria were focused on studies comparing the outcomes between surgical approaches at the abdominal and perineal locations, particularly on the recurrence rate, postoperative complications, and functional outcomes. In total, 21 studies were included in the review: these ranged from retrospective analysis and prospective studies to a multicentric randomized trial. In this review, abdominal approaches, particularly in the form of laparoscopic rectopexy, consistently demonstrated improved results compared to perineal techniques, with a much lower recurrence rate. The rates of mortality and morbidity were also remarkably lower in laparoscopic operations, which were advocated for suitable patients. However, perineal approaches, while still producing higher rates of recurrence, are a valuable alternative for elderly and high-risk patients due to their being relatively less invasive. Laparoscopic rectopexy can be considered a better surgical method for rectal prolapse, as it has a lower recurrence rate and better functional outcomes. In contrast, perineal approaches will have their place in the management of rectal prolapse, given patient selection for patients at high risk with regard to surgery. Future research should be directed toward multicenter trials with long-term outcomes in order further to fine-tune surgery strategy and criteria for patient selection.
