Nonampullary duodenal subepithelial neuroendocrine tumor removed R0 by ESD

Post written by Borathchakra Oung, MD, from the Department of Endoscopy and Gastroenterology, Edouard Herriot Hospital, Lyon, France. Managing lesions endoscopically in the duodenum can be challenging due to its thin wall and anatomically narrow lumen that limit endoscope maneuver. We reported a case of a subepithelial neuroendocrine tumor located in duodenal bulb just behind …
