Abstract
The patient was a 78-year-old man who had a pancreaticoduodenectomy for main duct intraductal papillary mucinous carcinoma (IPMC) in January 2010. A blood analysis in September 2010 showed the progression of anemia and increased tumor marker; a bleeding tumor at the pancreaticogastrostomy portion was identified by gastric endoscopy. We performed total resection of the remnant pancreas combined with partial gastrectomy and splenectomy. Histopathological diagnosis was IPMC. This diagnosis suggested that the tumor was likely to be a local recurrence or multiple metachronous lesions. Intraductal papillary mucinous neoplasm (IPMN) is a mucin-producing tumor which contains various histological types from benign tumors to malignant tumors. The prognosis of invasive IPMC is better than that of ordinary typed pancreatic cancer. As patients with IPMN have the possibility of local recurrence, multicentric occurrence in the remnant pancreas, occurrence of ordinary-typed pancreatic cancer, and extrapancreatic cancer, we should follow-up these patients carefully.
