[Congenital bronchoesophageal fistula in an adult; an undiscribed mechanism of symptom tolerance].
We present a case of a congenital bronchoesophageal fistula in a 61-year-old woman. She was referred to hospital because of postprandial heart burn. Three-dimensional (3D) computed tomography (CT) demonstrated an anastomosis between her right intermediate bronchus and esophagus. In spite of direct communication between her bronchus and esophagus, she has never suffered severe infection. We visualized the orifice of fistula closed with mucosal flap in swallowing by means of a bronchofiberscope. The delay of a diagnosis was explained by symptom tolerance. Some theories as to the symptom tolerance are found in literatures, but we supposed to find an undiscribed mechanism; closure of the orifice in swallowing. The fistula was surgically closed.
