Abstract

Polytetrafluoroethylene (PTFE) grafts are artificial vascular grafts commonly utilized for reconstructing the middle hepatic vein during living donor liver transplantation. In this report, we present three cases of expanded PTFE (ePTFE) graft migration into the gastrointestinal tract. These migrations were incidentally discovered and later migrated grafts were successfully removed endoscopically. The first case involved a patient presenting with epigastric discomfort, with a migrated ePTFE graft observed in the duodenal lumen during esophagogastroduodenoscopy (EGD). In the second case, a patient who visited the emergency room with hematochezia was found to have a migrated ePTFE graft in the colonic lumen on colonoscopy. The third case involved a patient undergoing regular EGD after endoscopic submucosal dissection for early gastric cancer; graft migration into the duodenal lumen was documented over time through sequential surveillance EGDs. The graft was endoscopically removed after complete migration. Contrary to previous reports, the three cases presented here did not exhibit serious clinical symptoms, and they were successfully treated through endoscopic foreign body removal without complications. We believe these occasions were possible due to the slow migration of the graft and the concurrent spontaneous closure of the fistula tract.
