Duodenum preservation in pancreatic head resection to maintain pancreatic exocrine function (determined by pancreatic function diagnostant test and cholecystokinin secretion)

摘要

Organ-preserving surgery, such as pylorus-preserving pancreatoduodenectomy (PPPD), duodenum-preserving pancreatic head resection (DPPHR), or medial pancreatectomy (MP), is one of the recent advances in pancreatic surgery. There was a previous report that preservation of the duodenum maintained pancreatic function. However, concerning the resected pancreas, patients were divided into two groups; one group included pancreatic head resections such as Whipple, PPPD, and complete DPPHR, and the other group included MP that removed only the pancreatic neck and preserved the pancreatic head and distal pancreas. The present study was designed to clarify the significance of duodenum preservation, in comparison with duodenum removal, in patients with pancreatic head resection, in terms of pancreatic function, determined by a pancreatic function diagnostant (PFD) test and cholecystokinin (CCK) secretion.
