A case of congenital bronchoesophageal fistula was treated surgically. A 45 year-old woman has been suffered from coughing with liquid diet and recurrent pneumonia for 20 years. Esophagogram and bronchoscopy revealed a fistula tract between midesophagus and right lower lobe bronchus just opposite site of the orifice of the superior segmental bronchus. Preoperative laboratory results were normal and Mantoux test was also negative. The fistula was dissected without difficulty and the lumen was covered with intact mucosa and there were no calcified lymph nodes around the lesion. The fistula was divided and closed with interrupted silk sutures on both sides. The postoperative course was uneventful.[KTCS 1979;2:110-112]
