Rectal and sigmoid atresia: transanal approach.

We report 2 patients with rectal and low sigmoid atresia operated on, respectively, at 6 and 3 months of age using the transanal approach, similar to the transanal technique for Hirschsprung disease, after exploratory laparotomy with colostomy at birth. There were no intraoperative or postoperative complications after a follow-up time of 2 years. After closure of the colostomy, both patients had no fecal incontinence. The transanal approach is a safe and effective technique in the management of rectal and sigmoid atresia.
