title: Gastric heterotopia in rectum complicated by rectovesical fistula.
abstract: Heterotopic gastric mucosa in the rectum produced a rare complication of rectovesical fistula. Diagnosis was made by direct biopsy and 99mTc scanning. Excision of ectopic gastric mucosa, diverting colostomy, and repair did not result in closure of the fistula. Endorectal pull-through constituted definitive treatment.
