[Intraoperative localization of recurrent pancreatic insulinoma-a resected case of the metastatic lesions in the residual pancreas and the lymph node].
We describe herein a 39-year-old woman with tumor recurrence in the residual pancreas and metastasis to the lymph node about 5 years after an eneclation for insulinoma in the body of the pancreas. A certain day in the morning in June 2002, she was immediately admitted to our hospital due to impairment of consciousness based hypoglycemia. On diagnostic imaging including an arterial stimulation venous sampling, localization of the recurrent lesions was not identified. In October 2002, we underwent laparotomy for the purpose of localization of the recurrent lesions and treatment. During the operation, peripheral blood glucose level, portal blood glucose level and portal insulin level were measured periodically. The mobilization started from the tail of the pancreas. Blood glucose levels were gradually elevated during the mobilization. The pancreas was mobilized to the right edge of the portal vein and was resected. Histopathological diagnosis was recurrent insulinoma in a peripancreatic lymph node and intra-pancreatic subcapsular tumor embolization. Postoperative course was uneventful. More than 8 years after surgery, she is doing well without signs of recurrence.
