Case Series of Endoscopic Submucosal Dissection (ESD) for Early Remnant Gastric Cancer After Subtotal Gastrectomy

Abstract

Background: ESD for early gastric cancer (GC) is technically well established, and accepted as a less invasive treatment than gastrectomy. ESD for remnant GC is technically difficult because of the narrow working space, severe fibrosis and stapling instrument around the suture line. However, there are few reports on ESD for remnant GC. Aim: This case series was to evaluate the feasibility and efficacy of ESD for early remnant GC. Method: The indication of ESD for early GC in our institution is an intramucosal differentiated adenocarcinoma without ulceration, or with ulceration only if the tumor size is 3 cm or less in diameter.
