RESUMO
Objective:To evaluate superior mesenteric artery preferential approach in the borderline resectable pancreatic head cancer.Methods:The clinical and follow-up data of 90 patients with borderline resectable pancreatic head cancer who underwent radical pancreatoduodenectomy at Beijing Chaoyang Hospital,Capital Medical University from Jan 2015 to Dec 2021 were analyzed.Results:After exploring the superior mesenteric artery in the lower colon area to confirm the vascular invasion meet the resection criteria, the blood supply is cut off first, then the tumors were resected en bloc, with the invaded vessels resected and reconstructed or replaced. All 90 patients successfully completed the operation without perioperative death. Pathology established pancreatic ductal adenocarcinoma. The 1-year, 2-year, and 3-year disease-free survival rates of patients in the arterial priority approach group were 68.2%, 60.4%, and 54.3%, while the 1-year, 2-year, and 3-year disease-free survival rates of patients by conventional approach were 58.4%, 26.4%, and 11.7% ( P=0.001). Conclusion:The superior mesenteric artery preferential approach in the inferior colon region can prolong the survival time of patients after surgery, and reduce the recurrence.
