腹腔镜胰十二指肠切除术的关键难点在于胰头钩突、肠系膜上动脉及门静脉-肠系膜上静脉轴周围的深部解剖。胰头同时接受腹腔干和肠系膜上动脉系统供血，静脉属支数量多、管壁薄且变异明显，单纯依赖术中出血后的反应性止血难以满足精准微创外科要求。手术入路与血流控制并非相互独立：不同入路决定关键动脉、静脉及胰头系膜的显露顺序，而主动、计划性的血流控制可使高风险解剖在低血流和可控制状态下完成。腹腔镜胰十二指肠切除术中应根据肿瘤位置、血管受侵及解剖变异情况选择手术入路并动态调整，通过关键动脉递进式去血供、主要血管预控制及静脉回流管理，优化胰头钩突及胰头系膜的解剖和血管处理顺序。合理选择并组合不同入路，由被动止血转向血供优先离断和选择性预控制，有助于提高腹腔镜胰十二指肠切除术的安全性、规范性及肿瘤根治性。

Laparoscopic pancreatoduodenectomy is technically demanding because the most critical steps involve deep dissection around the uncinate process, superior mesenteric artery, and portal-superior mesenteric venous axis. The pancreatic head receives dual arterial inflow from the celiac and superior mesenteric arterial systems, while its venous drainage consists of numerous thin-walled and variable tributaries. Therefore, reactive hemostasis after bleeding is often insufficient for precise minimally invasive surgery. Surgical approaches and blood flow control are interdependent: the approach determines the sequence of exposure of key vessels and the mesopancreas, whereas planned vascular control allows high-risk dissection to proceed under low-flow and controllable conditions. In laparoscopic pancreato-duodenectomy, surgical approaches should be selected and dynamically adjusted according to tumor location, vascular involvement, and anatomical variations, while stepwise arterial devascularization, pre-control of major vessels, and management of venous drainage can optimize the sequence of dissection and vascular management around the uncinate process and mesopancreas. Rational selection and combination of different surgical approaches, together with a transition from reactive hemostasis to priority devascularization and selective pre-occlusion, may improve the safety, standardization, and oncological quality of laparoscopic pancreatoduodenectomy.
