Long-term outcome of laparoscopic rectopexy for full-thickness rectal prolapse.

BACKGROUND

The aim of this study was to assess the long-term outcomes of laparoscopic rectopexy for full-thickness rectal prolapse (FTRP).

METHODS

Data of a prospectively maintained database were analysed. A structured telephone interview was conducted to assess a consecutive series of long-term outcomes of an unselected population who had laparoscopic rectopexy at a single centre between April 2006 and April 2014. The primary outcome was recurrence of FTRP. Secondary outcomes were functional outcomes and morbidity associated with the procedure.

RESULTS

A total of 80 patients (74 female, median age of 66 years, range 23-96 years) underwent a laparoscopic rectopexy, of whom 35 (44%) were for recurrent prolapse. Seventy-two patients (90%) had a posterior suture rectopexy, six (8%) had a ventral mesh rectopexy, one (1%) had a combination of both procedures, and one (1%) had a posterior suture rectopexy with a sacrocolpopexy. There was no conversion to open surgery. Three patients (4%) needed reoperation within 30 days after surgery: two due to small bowel obstruction and one for a suspected port site hernia. Seventy-four patients (93%) were available for either clinical follow-up (FU) or telephone interview and there were 17 (23%) recurrences of FTRP at the median FU of 57 months (range 1-121 months). The median time to recurrence was 12 months (range 1-103 months). Recurrence of FTRP was seen in nine patients (12%) within 1 year following surgery. A history of multiple previous prolapse repairs increased the risk of prolapse recurrence (odds ratio 8.33, 95% confidence interval 1.38-50.47, p = 0.020). Based on clinical follow-up of 71 patients up to 1 year, there were 41 patients (58%) who had faecal incontinence prior to rectopexy of whom two patients (5%) had complete resolution of symptoms and 14 (34%) had improvement.

CONCLUSIONS

Laparoscopic rectopexy is a safe operation for full-thickness rectal prolapse. The durability of the repair diminished over time, particularly for patients operated on for recurrent prolapse.
