Inferior branch-preserving superior head resection of the pancreas with gastric wall-covering method for intraductal papillary mucinous adenoma.

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas showed significantly less aggressive pathologic features compared with common pancreatic cancer. Therefore, several organ-preserving techniques, including duodenum-preserving pancreatic head resection, have been advocated in surgical procedures for IPMN. We describe a surgical technique of superior head resection of the pancreas with inferior branch preservation followed by a gastric wall-covering method for the prevention of pancreatic leakage in patients with IPMN of the pancreas head.
