Colonic atresia associated with Hirschsprung's disease: it is not a diagnostic challenge.

Colonic atresia Hirschsprung's disease association (CAHDA) is usually diagnosed after several failures of intestinal anastomoses. Having previously reported one of the cases of CAHDA, we established the diagnosis in a patient before attempting intestinal anastomosis for stoma closure. We herein report the first patient with CAHDA in the literature diagnosed before a therapeutic challenge. We recommend a biopsy of the distal colonic segment either during initial laparotomy or before attempting intestinal anastomosis for closure of colostomy to prevent therapeutic challenge in the patients with colonic atresia.
