Residual terminal bowel fistulating into the alimentary tract: a hitherto unreported complication of surgery for anorectal malformation.

The residual terminal bowel after pull-through surgery for anorectal malformation has been reported to cause urinary complications. We report two boys where residual bowel has fistulated postoperatively into the alimentary tract causing metabolic and septic complication in one and a large pelvic mass with urinary and rectal obstruction in the other.
