A 78-year-old man underwent esophagogastroduodenoscopy which revealed a subcircumferential 0-IIb lesion in the cervical to thoracic esophagus. On NBI magnified observation, the invasion depth was EP/LPM. Biopsy examination revealed carcinoma in situ, and endoscopic submucosal dissection (ESD) was performed. Considering that the risk of postoperative stenosis was high, as preventive measures, local steroid injection (160 mg) was administered, and prednisolone (PSL) 30 mg/day was started on the day after ESD for 8 weeks. Because postoperative stenosis was observed on the 63rd day after ESD, endoscopic balloon dilatation was performed and PSL at 30 mg/day was again administered orally for 8 weeks. The stenosis resolved without any obstruction. Currently, there is no established method for preventing stenosis after esophageal ESD, and it is necessary to accumulate more cases in the future.
