A 73-year-old woman was admitted to our hospital complaining of a hypoglycemic attack. Insulinoma was suspected from the clinical symptoms and endocrinological examinations. Anigography and dynamic computed tomography revealed an enhanced tumor of about 1.0 cm between the gastroduodenal artery and superior mesenteric vein. Intraoperative ultrasonography revealed a hypoechoic mass close to the main pancreatic duct (MPD). Segmental pancreatectomy with Roux-Y pancreatojejunostomy was performed to avoid injury of the MPD and to preserve the function of the residual pancreas. The postoperative clinical course was favorable. Depending on the localization of the tumor, this operative procedure seems to be a good indication.
