BACKGROUND
Laparoscopic repair of rectal prolapse offers the potential of lower recurrence rates for transabdominal repair coupled with the advantages of minimally invasive colorectal surgery. There have been no direct comparisons of the laparoscopic Wells procedure (LWP) and laparoscopic resection with rectopexy (LRR). This study is the first to make a direct comparison of outcomes from laparoscopic LRR and LWP repairs using a selected, symptom-based choice of operative procedure.
METHODS
Consecutive patients presenting with complete rectal prolapse were evaluated by clinical history of the degree of constipation, diarrhea, or incontinence. Patients with a history of constipation or normal bowel habits with normal continence underwent LRR, whereas those with diarrhea or anal incontinence underwent LWP. The collected data included age, gender, operative time, length of hospital stay (LOS), operative blood loss, complications, and postoperative symptoms of constipation or diarrhea. Continence was scored using the Cleveland Clinic scoring system.
RESULTS
Of the 24 patients, 11 underwent LRR and 13 had LWP. The patients in both groups were predominantly, female (LRR, 9/1; LWP, 10/2). The LRR patients were significantly younger (48.6 vs 63.9 years p <0.001). Both operative time and LOS were significantly longer in the RR group (operative time, 128.5 +/- 80.6 min vs 69.9 +/- 13.4 min; LOS, 3.6 +/- 3.1 days vs 2.2 +/- 1.03 days). All patients in the LRR group had constipation preoperative, and no patients were incontinent clinically. Preoperatively, 7 of the 13 patients in the LWP group had preoperative diarrhea, and 1 patient had clinical constipation. A five patients experienced clinical symptoms of fecal incontinence, manifested in different degrees. Postoperative complications occurred only in the LRR group (1 case of abdominal wall hematoma and 2 cases of prolonged ileus). During a mean follow-up period of 18.1 months, there were no recurrences; 10 of the 11 LRR patients had correction of constipation; and 4 of 5 of the incontinent LWP patients had improvement in their symptoms. Constipation developed in one LWP patient.
CONCLUSIONS
Clinical assessment of preoperative bowel function and continence allows accurate selection of the appropriate laparoscopic technique for repair of rectal prolapse without the added expense of anal physiologic testing. Although LRR may be associated greater morbidity than LWP, both procedures offer good functional outcome, with short LOS and low recurrence rates.
