A 65-year-old man was diagnosed to have Crohn's disease in 1989. In 1991, frequent bronchitis developed, and bronchoesophageal fistula was diagnosed by esophagography. On esophagography and aortography, the disease was diagnosed to be Type IV based on Braimbridge's classification accompanied by pulmonary sequestration. A thoracoscope-assisted fistelectomy was performed. This paper reports the findings of a fistelectomy assisted by thoracoscopy for the treatment of a Type IV bronchoesophageal fistula according to Braimbridge's classification accompanied by Crohn's disease.
