The preservation of left colonic artery (LCA) has been accepted by more and more surgeons in the radical resection of rectal cancer, but whether it can reduce anastomotic complications and affect the oncology efficacy remains controversial. This consensus elaborates the significance, anatomical structure, key points of operation techniques, indications and contraindications, and surgical approaches of LCA preservation. Each statement and recommendation was recognized by most experts in the field of colorectal surgery. The purpose of this consensus is to improve the cognitive level of Chinese colorectal surgeons on LCA preservation, so as to standardize the surgical strategies and methods of LCA preservation and furthermore practice, and promote it. The pending issues in this consensus need further high-quality clinical studies.
