[Rare complications in surgically treated rectal and anal atresia with submucous pull-through of the rectal mucosa].

Two rare complications after Rehbein's pull-through operation are reported. The first case is a four-year-old child producing at two times a urethral-rectal-muscle cuff fistula, the rectal muscle cuff being filled with urine. The second case deals with a now fourteen-year-old boy in whom a mucosa-regenerated rectal muscle cuff led to an enterogenous cyst of double fist size.
