AIM: Full-thickness rectal prolapse is common in the elderly, but there are no particular practice guidelines for its surgical management. We evaluated retrospectively the perioperative and long-term clinical results and function in elderly and younger patients with complete rectal prolapse after robotic-assisted laparoscopic rectopexy (RALR). METHOD: Seventy-seven patients who underwent RALR between 2002 and 2010 were divided into Group A (age < 75 years, n = 59) and Group B (age > 75 years, n = 18). Operative time, intra- and postoperative complications, length of hospital stay, short-term and long-term outcomes, recurrence rate and degree of satisfaction were evaluated. RESULTS: There was no significant difference between the groups regarding operation time, conversion, morbidity or length of hospital stay. At a median follow-up of 51.8 (5-115) months, there was no difference in the improvement of faecal incontinence, recurrence and the degree of satisfaction. CONCLUSION: Robotic-assisted laparoscopic rectopexy is safe in patients aged over 75 years and gives similar results to those in patients aged < 75 years.
