Significance of para-aortic lymph node dissection in advanced gastric cancer.

Abstract

n2 is helpful in predicting para-aortic lymph node metastasis. Whereas, post-operative morbidity such as pancreatic fistula and respiratory complications after para-aortic lymph node dissection were significantly higher, they were controllable. Para-aortic lymph node dissection should be indicated in advanced gastric cancer patients in which lymph node metastasis is over n2 or invasion depth is deeper than the exposed serosa. But the number of positive para-aortic lymph nodes must be less than three.
