Bowel imbrication in the management of anorectal anomalies.
Four patients who had imbrication of their proximal rectum and distal sigmoid colon as part of the management of constipation following an anorectoplasty for an anorectal anomaly. Three children with an anorectal anomaly presented with constipation and marked dilation of the rectosigmoid portion of the large bowel; each had longitudinal imbrication of the dilated segment, via a left iliac fossa incision. The forth was born with a cloacal anomaly with associated colonic atresia. The small bowel was used to construct the anorectum following a redo anorectoplasty. Subsequently, the small bowel became ectatic, resulting in the patient developing persistent watery diarrhoea and severe perianal excoriation, which was managed with a 30 cm longitudinal imbrication of the distal bowel during an extensive laparotomy. All 4 have patients now have near normal bowel motions with minimal medication, after only a short hospital stay. Residual problematic dilatation of the rectosigmoid colon in patients with a high anorectal anomaly, in the presence of constipation, can be successfully managed by imbrication of the dilated segment, if carefully selected.
