[Operation evaluation: duodenum-preserving pancreatic head resection]

With the improvement of surgical techniques and deeper anatomical understanding, the concept of precision surgery has gradually developed. The necessity of traditional extensive organ resection for the treatment of benign and borderline tumors is being challenged due to the high risk of long-term complications. Over the past 40 years, various modified surgical techniques have emerged, with duodenum-preserving pancreatic head resection as a representative procedure. The surgical indications have gradually transitioned from chronic pancreatitis to benign and borderline tumors of the pancreatic head. The extent of resection has evolved from major partial resection and subtotal resection to total resection of the pancreatic head. The surgical approach has also progressed from traditional open surgery to minimally invasive techniques such as laparoscopic or robot-assisted surgery, reflecting updates and optimizations in treatment concepts and surgical methods. This paper discusses the development, surgical indications, and related complications of duodenum-preserving pancreatic head resection. The aim is to provide a reference for the more standardized and rational selection of this surgical procedure in clinical practice while reducing the incidence of complications.
