Pathological types of gastric cancer in stage ⅢC include T4a-SEN3, T4b-SIN2, T4b-SIN3. Celiac artery metastatic lymphadenopathy fused into blocks, usually from bottom to top. Limited operation space revealed anatomical and pathological factors, the dissection of the celiac artery lymph nodes, processing the left gastric artery root difficulty. Application of novel celiac artery lymph nodes dissection path, avoiding the limitation of the celiac artery lymph node dissection space exposure factors, so that the dissection of the celiac artery lymph nodes is more complete, processing the left gastric artery root easily, reduce the amount of bleeding, shorten operation time, increase the average lymph node dissection and the ⅢC gastric cancer resection rate.
