Colobronchial fistula following a partial resection of the colon

We report a case of colobronchial fistula as a late consequence of the resection of the colon due to relapse of the gastrointestinal stromal tumor (GIST). A 54-year-old man experiencing pain in the left upper abdominal region underwent doublecontrast barium enema which revealed a fistulous channel between the splenic flexure of the colon and the bronchial tree. Fiberoptic bronchoscopy, after an extensive washout and aspiration of barium sulphate, confirmed the existence of a fistula in left lower subsegmental bronchi. The patient underwent left lower lobectomy, resection of the colobronchial fistula and resection of the splenic flexure of the colon. A year after the operation, the multidetector computed tomography (MDCT) showed neither signs of malignant abdominal disease, nor signs of pathological changes in the lung bases.
