"after esophagectomy for cancer a fistula developed between the trachea and the pulled-up stomach because of the ischaemic effect of the tracheostomy tube. At single stage repairs, the fistulae were divided and the gastric defects were closed directly...Treatment of this potentially life threatening and rare condition yielded excellent results."
