Abstract    The lymph nodes dissection manner and range are dependent on the special characteristic of lymphatic drainage of rectum. However，lateral lymph node dissection (LLND) for low rectal cancer is still a controversial issue. Lateral lymph node dissection might decrease local recurrence of patients with rectal cancer, but with increasing risk for operation-related complications and uncertainty in improving long-term survival. Combined with preoperative imaging evaluation and sufficiently multidisciplinary discussion, plus an appropriate surgical indication, prophylactic lateral lymph node dissection still has a broad space for application.
