In a case of 51-year-old woman with an esophago-bronchial fistula located in the right B2 bronchus, we found a tubular type of esophageal duplication communicating with the esophagobronchial fistula by examinations of esophagography and endoscopy. It was diagnosed as tubular type I double barreled type of esophageal duplication by Akaboshi's Classification. She successfully underwent resection of the accessory esophagus combined with the fistula and the adjacent pulmonary tissues. Squamous epithelium and smooth muscle tissue were observed in the resected esophageal specimen. Double barreled type of esophageal duplication is one of the rare malformation, and we have found 12 reported cases including our one case in the Japanese literatures. Moreover our case is the first one whose accessory esophagus were combined with an esophagobronchial fistula.
