Report of a Case: Tubular Duplication of Terminal Ileum and Entire Colon With Rectovaginal Fistula and Normal Anus

Abstract

We report a rare case of tubular duplication of the terminal ileum and the entire colon with a rectovaginal fistula and a normal anus in a female patient. She was suspected of having duplication of the urinary bladder prenatally. After birth, we diagnosed her as having a rectovestibular fistula with a normal anus and performed colostomy. During the operation, we encountered tubular duplication of the terminal ileum and the entire colon, complicated by duplicated urethra, vagina and uterus. When the patient was six months of age, we performed closure of the rectovaginal fistula and side-to-side anastomosis of the duplicated rectum, but the rectovaginal fistula recurred postoperatively. When the patient was eight months of age, we carried out reclosure of the fistula and performed resection of the duplicated ileum and ascending colon, partial resection of the septum, and stoma closure two months later. Her postoperative course was uneventful.
