Abstract
We describe a case of intraductal papillary mucinous carcinoma (IPMC), 25 years following pancreaticojejunostomy (Partington-Rochelle). A 76-year-old man presented to the emergency unit with abdominal pain and a fever. Past medical history revealed a pancreaticojejunostomy (Partington-Rochelle) undertaken 25 years previously. Abdominal enhanced computed tomography showed a papillary cystic tumor of the pancreatic body, which had infiltrated the jejunum, showing a ‘dirty fat’ sign. Intraductal papillary mucinous neoplasm was diagnosed and emergency surgery undertaken. Surgical findings revealed a large tumor in the pancreatic body, with infiltration in the pancreaticojejunostomy anastomosis and jejunum, and a large amount of mucus accumulation. Distal pancreatectomy with D2 lymph node dissection and resection of the jejunum anastomosis was undertaken. Based on histopathological findings, IPMC was diagnosed. An investigation of the literature revealed no reports of IPMC occurring at the site of pancreaticojejunostomy anastomosis, suggesting that this is the first case in Japan.
