Temporary Portal Vein Bypass for Resection of Pancreatic Neoplasms.

Objective: We analyzed perioperative outcomes of patients undergoing pancreatectomy with portal vein resection for pancreatic cancer using temporary intraoperative mesoportal or mesocaval bypass.

Summary Background Data: Pancreatectomy for advanced pancreatic cancer with long-segment involvement or complete occlusion of the mesoportal venous axis and cavernous transformation represents a major technical challenge. To avoid major bleeding as well as to overcome severe bowel congestion or ischemia due to long portal venous clamping, a mesoportal or mesocaval venous bypass graft first approach has been proposed.
