We report a case of esophageal stenosis after corrosive esophagitis due to sodium hydroxide.<br>A 31-year-old man, who drank sodium hydroxide by mistake after drunken alcohol heavily, underwent treatment for acute phase of corrosive esophagitis as well as conservative therapy including dilatation of the esophagus for cicatrical stenosis at another hospital. However, no symptomatic remission of swallowing difficulty was attained and the patient was referred to the hospital for the purpose of operation. Upper gastrointestinal series and endoscopic study revealed prominent encircling stenosis of the esophagus and sclerosis of the wall involving from the upper intrathoracic esophagus to esophagogastric junction. An endoscope could not pass through the esophagus. Chest magnetic reso-nance imaging scan also showed the same findings. A subtotal esophagectomy was performed for extensive cicatrical stenosis over the entire circumference of the esophagus, and the gastric tube was used for reconstruction. After the operation, his swallowing difficulty was improved. However, a problem of cancer change of the remnant esophagus is still left as a late complication, so that a long-term observation of the clinical course would be mandatory.
