Completely Divided Colostomy of the Sigmoid Colon for the Management of Anorectal Malformations in Our Institution

Abstract

Purpose: The aim of this study was to confirm the efficacy of completely divided colostomy of the sigmoid colon in the management of anorectal malformations in our institution.

Methods: The cases of 10 patients who underwent completely divided colostomy of the sigmoid colon for anorectal malformations at our hospital between April 2009 and June 2016 were studied. We retrospectively investigated complications related to the colostomy, the diameter of the distal rectum before radical surgery, and urinary tract infections. The diameter of the distal rectum was evaluated using the anteroposterior diameter on a preoperative examination.

Results: All 10 patients were male. Four had prostatic fistulas, and six had bulbar fistulas. The following colostomy-related complications were observed: surgical site infections, 0; prolapse, 0; stenosis, 0; difficulty setting up the stoma pouch, 3. There were no difficulties in pulling through the rectum owing to restrictions caused by the colostomy during the radical surgery in none of the patients. In addition, none of the patients required colostomy reconstruction. A urinary tract infection was detected before the radical surgery in one patient. The median diameter of the distal rectum was 1.75 cm.

Conclusions: Completely divided colostomy of the sigmoid colon caused few complications, and our results suggest that it did not dilate the distal rectum.
