A 68-year-old male visited the hospital presenting swallowing difficulty that persisted for 30 years. In the military service, the patient accidentally ingested glacial acetic acid and esophageal obstruction was developed. Transverse and left colon was used for reconstruction for esophagus. The colon was pulled up via substernal route and anastomosed to pyriform sinus proximally and body of stomach distally. Partial resection of the manubrium and clavicular head was performed to avoid interference with the passage of the esophageal substitute. There was no operative complication except vocal cord palsy. Under fluoroscopy, the swallowing time of barium from the pharynx to the level of the diaphragm was 4 to 6 seconds. The patient could swallow solid food without aspiration, obstruction, or significant regurgitation 2.5 months after the surgery.
