Long-term functional results of colon resection and rectopexy for overt rectal prolapse

Abstract

We reviewed the long-term functional results of colon resection and suture rectopexy for complete rectal prolapse in 47 patients followed for more than 3 yr (mean 65 months). Thirty-three patients underwent sigmoidectomy, eight patients underwent subtotal colectomy, and four patients underwent sigmoidectomy with subsequent subtotal colectomy. Three patients (6.3%) developed recurrent full-thickness prolapse, and four patients (8.5%) developed rectal mucosal prolapse. Twenty patients presented with constipation, 10 (50%) of whom improved after surgery. Constipation improved in seven (70%) patients who underwent subtotal colectomy. Twenty-one patients presented with incontinence, eight (38%) of whom improved. Continence worsened in six patients, and four patients developed significant diarrhea. These complications did not correlate with the extent of bowel resection. Three patients required subsequent stomas. Colon resection and rectopexy provides long-term control of rectal prolapse with an acceptable recurrence rate. Subtotal colon resection is frequently helpful in patients with associated constipation. However, colon resection of any magnitude entails a small risk of chronic diarrhea and/or diminished continence.
