Abstract    Lateral lymph node dissection（LLND） is one of the important operations for the treatment of rectal cancer. With the application of the neoadjuvant chemoradiation therapy，this operation is less performed in the Europe，America and China. Currently，the researches on this operation are mainly from Japan and South Korea. There is controversy of its effect on the lowering the local recurrence and improving the long-term outcomes，especially for the prophylactic LLND. For the patients with suspected lateral lymph node metastasis after neoadjuvant chemoradiotherapy，LLND is commonly indicated. The diagnosis of lateral lymph node metastasis is relied on the precise assessment of imaging. LLND is one kind of massively invasive procedure，but it is one important component of the operations for rectal cancer. Combining with mini-invasive techniques of the laparoscopic and robotic procedures，LLND can be selectively applied to improve the outcomes for the indicated patients.
