A 71-year-old man was admitted to our hospital for repetitive vomiting. Only a small intraductal papillary-mucinous neoplasm (IPMN, 28mm in diameter) in the body of pancreas was seen by several practical examinations, however no cause of intestinal obstruction was found. Since he suffered from vomit and nausea for a long time, laparotomy was done. During the laparotomy, several white nodules were found around pancreas, and the nodules were proved to be adenocarcinoma. Therefore, we diagnosed the duodenal obstruction due to peritoneal dissemination of intraductal papillary-mucinous carcinoma (IPMC). Then, gastrojejunostomy was performed. This is a first case of peritoneal dissemination of IPMC without apparent findings of pancreatic invasion.
