LVMR Versus PSR for External FTRPin Elderly Patients

In frail patients with external full-thickness rectal prolapse (FTRP), the exact postoperative recurrence and functional result outcomes difference between Laparoscopic ventral mesh rectopexy (LVMR) and perineal stapler resection (PSR) have not been investigated, leading to ineffective treatment. Objectives: Evaluating the efficacy of PSR versus LVMR for treating external FTRP in the elderly. Design: This was a retrospective study that involved multiple centers. Settings: This study was conducted in the colorectal surgical units of our Universities' Hospitals Patients: 330 elderly patients divided into LVMR group (250), and PSR (80) between April 2012 and April 2019. Before and after surgery, patients were evaluated using the Wexner Incontinence Scale, the Altomare Constipation Scale, and the patient's satisfaction. Main outcomes measurement: The primary outcome was the recurrence rate and risk factors of FTRP. Secondary outcomes were postoperative incontinence and constipation and patients' satisfaction.
