Histological confirmation of healing of gastrobronchial fistula using a muscle flap

We report a case of gastrobronchial fistula that developed after esophagectomy for esophageal cancer. The fistula was repaired successfully by transposing a pectoralis major muscle flap. Complete healing was confirmed histologically by epithelialization of the fistula site and at autopsy 12 months after surgery. Muscle flap transposition effectively repairs gastrobronchial fistula.
