A case of superficial spreading type of esophageal cancer resected endoscopically with combination of methods for prevention of stricture

Esophagogastoroduodenoscopy showed this lesion needed com- plete circular ESD which has high risk of esophageal stricture after ESD. To prevent esophageal stricture after ESD, we per- formed ESD forming minimum mucosal defect, placed polyglycolic acid sheet over the surgical wound after resection, and ad- ministered oral prednisolone after ESD. This combination of methods for prevention of stricture after ESD were effective, and this patient had not required endoscopic balloon dilation yet.
