Congenital bronchoesophageal fistula without esophageal atresia is very rare and often has an insidious clinical course that occasionally persists into adult life. Here are presented five cases of congenital bronchoesophageal fistula without esophageal atresia in adults treated successfully in the Seoul National University Hospital. The patients included two women and three men in the range of 16 and 45 years old. [mean age: 32 years old] Three of five cases could be diagnosed preoperatively by esophagogram and bronchogram but two of them could only be found in operative field. Cineesophagogram is recommended, on review of the literature, to be the most rewarding diagnostic procedure.[KTCS 1983;3:381-385]
