Early esophageal squamous cell carcinoma and diverticulum were cured simultaneously by endoscopic submucosal dissection in a patient.

Abstract

Early squamous cell carcinoma (SCC) in esophageal diverticula is rare, with an unclear pathogenesis [1]. Endoscopic septotomy is used to treat patients at high risk for surgical resection of a diverticulum [2], and endoscopic submucosal dissection (ESD) is recommended for selected early esophageal carcinoma [3]. ESD for early cancer in diverticula is challenging for endoscopists, as diverticula have characteristically thin walls and endoscopic treatment carries a higher risk of perforation [1] [4]. Here, we report a case of ESD curing early esophageal SCC in diverticula.
