Changing approaches to rectal prolapse repair in the elderly.

Aim: The abdominal approach to rectal prolapse is associated with lower rates of recurrence but a higher chance of complications and has been traditionally reserved for younger patients. However, longer life expectancy and wider use of laparoscopic techniques necessitates another look at the abdominal approach in older patients.

Methods: This was a retrospective review of data from patients undergoing abdominal repair of rectal prolapse between 2005 and 2011.

Results: Forty-six abdominal repairs (laparoscopic or open suture rectopexy, sigmoidectomy and rectopexy and low anterior resection) were performed during the study period. Twenty-nine repairs (63%) were performed in patients under the age of 70 (average age 51) and 17 (37%) in patients older than 70 (average age 76; range 71-89). Most of the cases performed during the initial 3 years of the study were via laparotomy. However, in the last 4 years, the laparoscopic approach was used in 83% of younger patients and 69% of older patients. Average length of stay was 2.6 days for younger and 3.8 days for older patients. Both groups had similar rates of re-admission: 20% vs 23%. The rate of wound infection was higher in the younger patients (5% vs nil). However, rates of urinary tract infection, two instances (10%) vs four (30%), urinary retention, one instance (5%) vs two (15.4%), ileus, one instance (5%) vs two (15.4%) were higher in the older group.

Conclusion: Wider use of laparoscopy has precipitated a change in the approach to rectal prolapse in older patients. Although associated with a slightly higher rate of post-operative complications, the abdominal approach to rectal prolapse is feasible, safe and effective in patients older than 70 years.
