Abstract    There were still some technical issues, such as surgical approach, and lymphatic dissection, which were still under debate. Based on clinical practice, the following recommendations are proposed: (1) Determine the type of inferior mesenteric artery through abdominal CT angiography before surgery, and use the intermediate combined cephalic approach for surgery, which is conducive to accurate preservation of LCA. (2) Standardized dissection of No.253 lymph nodes is necessary during the preservation of LCA. (3) The use of the "6-321 Risk Assessment Scale for Anastomotic Leakage after Low Rectal Cancer Surgery" can accurately predict the occurrence of anastomotic leakage after low rectal cancer surgery, providing a direct and beneficial reference standard for whether preventive stoma should be performed simultaneously during surgery.

Key words: laparoscopic assisted radical resection of rectal cancer, medial-to-lateral approach, inferior mesenteric artery type, left colonic artery, No. 253 lymph node, anastomotic leakage
