Eligibility Criteria
Inclusion Criteria: Over 18 years old Preoperative imaging suggested the presence of space occupying in the head of the pancreas, ampullary abdomen, and distal common bile duct tumor lesions to be treated with Pancreaticoduodenectomy No obvious arterial invasion, no obvious venous invasion or vein invasion but can be replaced No distant transfer Complete clinical data Exclusion Criteria: With tumors of other organs Patients unable to tolerate anesthesia and operation due to serious abnormalities in functions of heart, lung and other important organs Patients found intraoperative peripheral organ metastasis combined with excision of other organs or found intraoperative radical excision could not be performed and underwent palliative drainage surgery or end the surgery Preoperative adjuvant therapy was given Clinical data are seriously missing

The intermediate approach
The standard approach
The key point of surgery in the standard approach group was to first reveal portal vein-superior mesenteric vein and gradually complete the resection of the uncinate process of pancreas based on the reference of portal vein-superior mesenteric vein.
The area between superior mesenteric artery and superior mesenteric vein was defined as the intermediate area and dissection was performed in this area to achieve the removal of the uncinate process of pancreas.
