A 67-year-old man was referred to our department after a foreign body was found in the descending duodenum during routine EGD. Although initially suspected to be metallic, but CT did not show any obvious foreign bodies. A subsequent EGD at our institution identified a bag closure adherent to the inferior duodenal angle, forming a mucosal fistula. Considering the low possibility of dropout from the duodenum during the session, removal of the bag closure was deferred, and we performed experiments on the deformation and damage of the bag closure using endoscopic instruments outside the body. After two weeks, endoscopic removal was successfully achieved using a hard hood and grasping forceps to deform and extract the bag closure without complications. Here, we report a rare case of endoscopic removal of a bag closure adherent to the duodenal mucosa, forming a fistula.
