Abstract

There have been an increasing number of reports of intraductal papillary mucinous neoplasm (IPMN) of the pancreas since its first report by Ohhasi et al. in 1982. However, fistula formation associated with IPMN to other organs is rare. A 79-year -old woman visited our hospital due to diarrhea and dyspepsia for 3 months. Abdominal computed tomography and magnetic resonance imaging revealed IPMN of the pancreas and fistula formation in the stomach. Endoscopic retrograde cholangiography after injecting a dye through the pancreatic duct showed dye flowing out into stomach. An endoscopic biopsy was carried out through the pancreatogastric fistula and this tumor was confirmed to be IPMN. We report a case of pancreatogastric fistula associated with IPMN that was confirmed by histology. (Korean J Gastrointest Endosc 2006;33:257⁣261)
