60s male who had undergone multiple balloon dilatations for esophageal stricture after two endoscopic submucosal dissection procedures suffered perforation of the esophagus during the fourth dilatation. The prognosis was considered good, and the patient was hospitalized and treated conservatively with drainage tubes placed in the esophagus and stomach. On the 6th day, blood tests and CT scan showed improvement, so the drainage tube was removed and the patient resumed drinking on the 8th day. On the 12th day, esophagography confirmed that there was no problem, and enteral nutrition was started, and the patient was discharged on the 14th day. Esophageal perforation caused by balloon dilation can avoid surgical treatment by choosing conservative treatment if the prognosis is judged to be favorable.
