title: Funnel anus and megacolon in an adult.
abstract: A case of congenital funnel anus associated with consequent megacolon and rectosigmoidal inertia is described for the first time in a 36-year-old man. This very rare condition, a variant of low translevator anorectal malformation, did not improve after dilatation, but was treated successfully by extended left hemicolectomy and stapled coloanal anastomosis.
