Abstract    Whether lateral lymph node dissection (LLND) is routinely performed in the surgical treatment of rectal cancer remains controversial，and whether LLND can be standardized is also one of the focuses of controversy. Compared with open surgery, laparoscopic surgery is considered more suitable for LLND because of its minimal invasiveness，magnifying effect and perfect pelvic vision. The knowledge of rectal lymphatic drainage system and pelvic autonomic nerve anatomy is important for the implementation of LLND in laparoscopic rectal cancer，especially for the preservation of sexual and urinary function. It is suggested to dissect accurately in the inner, intermediate and outer spaces around the rectum，to preserve the pelvic autonomic nerve and complete lateral lymph node dissection for rectal cancer.
