Double termination of the alimentary tract has two types (Perineal Canal and acquierd type or a kind of periproctic abscess). Congenital type has squamouse epithelium and muscle in submucosa of the fistula. But the differentiated diagnosis of two types by clinical aspect is difficult. We experienced fourteen female infants with double termination of the alimentaly tract. Four cases were congenital type, five cases were acquired type and five cases were of unknown etiology. Surgery is the only treatment for the congenital type, but acquired type can be cured by coservative treatment. Our experience disclosed that four out of five cases of aquired type were cured by conservative treatment. The first choice of treatment is therefore conservative treatment before 6 months after birth. After 6 months if the fistula is not closed, operative treatment must be doned. We think vestibulo-anal pullthrough procedure without colostomy is the best operative methode for this disease.
