A 62-year-old man underwent pancreaticoduodenectomy (PD) for intraductal papillary mucinous carcinoma (IPMC) in 2006. No signs of adenocarcinoma at the resection margin were found by intraoperative pathological examination of frozen sections. The postoperative pathological diagnosis was invasive carcinoma derived from IPMC and moderately differentiated tubular adenocarcinoma. A blood analysis in 2011 showed serum (CA19-9) to be increased since the initial resection. Imaging test showed a recurrent tumour at the site of the pancreaticogastrostomy (PG) in the remnant pancreas. We conducted total remnant pancreatectomy for recurrent IPMC and partial gastrectomy. Because both lesions had a histopathological resemblance, the pathological diagnosis was recurrent invasive IPMC. Based on this experience, it is important to facilitate early detection by annual check-up. And also, we recommend PG as a reconstructive intervention in patients at high risk of IPMC recurrence in the remnant pancreas following PD as it is grossly visible on upper gastrointestinal endoscopy.
