Is it necessary to dissect the posterior lymph nodes along the splenic vessels during total gastrectomy with D2 lymphadenectomy for advanced gastric cancer?

Although No.10p LN dissection might retrieve more No.10 LNs, operation times were longer, and the number of positive No.10 LNs and the OS rate were not improved. It might be no necessary to dissect No.10p LNs during total gastrectomy with D2 lymphadenectomy for AGC.
