Gastric endoscopic submucosal dissection via gastrostoma before the second operation for esophageal perforation: A case report

Abstract

A 69-year-old man with advanced esophageal cancer and 2 early gastric cancers received chemoradiotherapy and was scheduled to undergo subtotal esophagectomy after gastric endoscopic submucosal dissection (ESD). However, left lower esophageal perforation induced by vomiting suddenly occurred, and he urgently underwent esophago-proximal gastrectomy and gastrostomy without reconstruction. The resected specimen showed a complete response of pretreatment for the esophageal cancer and radical resection of one gastric cancer. Radical resection of the other gastric lesion was necessary before reconstruction. The fistula of gastrostoma was gradually dilated from 6.7 to 9.3 mm in order to pass the endoscope. At nine months after emergent operation, gastric ESD was performed via only the gastrostoma. A hemoclip with thread was attached to the specimen, and the thread was pulled out of the gastrostoma. The specimen was able to be removed en bloc, resulting in radical resection. Gastric tube reconstruction through the posterior sternal route was performed at six months after the ESD. He has not developed recurrence of the esophageal or gastric cancer in the two years since the emergent operation.
