[Blood flow control techniques in pancreatic surgery]

Pancreatic surgery faces severe challenges regarding intraoperative bleeding risk due to complex anatomy and dense vascularity, which is a common difficulty in both open and minimally invasive procedures. Based on the blood supply characteristics of the pancreatic region, this article systematically proposes a blood flow control technical system covering three regions: the pancreatic head, the mid-pancreas, and the pancreatic body-tail. It emphasizes the strategy of "priority devascularization and pre-blocking" to prioritize the identification and control of critical vessels, thereby creating a bloodless or low-bleeding surgical field, improving surgical safety and oncological radicality, and promoting blood flow control technology as a new paradigm in pancreatic surgery.
