Abstract    D2 lymph node dissection is the standard surgery of Local advanced gastric cancer(LAGC). However, the value of para-aortic lymph node dissection(PAND) in LAGC patients remains controversial. For LAGC patients limited to No.16a2and No.16b1 metastasis without other non-curative factors, through multidisciplinary consultation, evaluation and discussion should be performed. After screening out para-aortic lymph nodes dissection（PAND）benefit groups, D2+PAND should be expanded to achieve R0 removal after receiving neoadjuvant therapy. With the rapid development of laparoscopic technology, clinical researches have confirmed that the effect of laparoscopic surgery is no less than that of open surgery in patients with advanced gastric cancer. Therefore, laparoscopic LAGC surgery also has certain clinical application prospects. However, for LAGC patients with NO.16 lymph node metastasis, rationally selecting treatment mode and normalizing laparoscopic PAND surgery is still a challenge for clinicians.
