HOW TO MANAGE DUODENAL TUMORS WITH EMR OR ESD

Abstract

Sporadic nonampullary duodenal adenomas are extremely uncommon. Furthermore, the incidence of duodenal tumors for which endoscopic resection (ER) is indicated is low, and moreover there are no guidelines for the indication, treatment methods, and how to manage the post-ER course. When considering EMR or ESD for duodenal tumors, it is more difficult to carry out endoscopic resection in the duodenum than in the stomach, because of the thin wall and narrow lumen of the duodenum. We describe herein how to manage duodenal tumors via endoscopic treatment methods.
