Middle-preserving pancreatectomy for multifocal intraductal papillary mucinous neoplasms of the pancreas: report of a case.

Multifocal or continuous pancreatic lesion is identified frequently but finding an appropriate surgical approach is quite challenging. Total pancreatectomy is a useful procedure. However, postoperative endocrine and exocrine disturbance is inevitable. Recently, the safety and feasibility of parenchyma preserving pancreatectomy, including middle-preserving pancreatectomy (MPP), have been reported. MPP is a combined procedure of pancreaticoduodenectomy and distal pancreatectomy, while preserving the body of the pancreas, for cases of multifocal pancreatic lesions. So far, there have only been a few reports that have described MPP. We report a case of MPP for multifocal intraductal papillary mucinous neoplasms of the pancreas, describe the surgical procedure, and discuss the feasibility of MPP as parenchyma-preserving pancreatectomy with reference to the literature.
