BackgroundD2 lymphadenectomy including No.10 lymph nodes (LNs) is the standard procedure for treating advanced gastric cancer (AGC) via total gastrectomy. However, there was no research focusing on the posterior LN dissection along the splenic vessels (No.10p LNs). This study is performed to assess the effect of dissecting No.10p LNs.MethodsWe analyzed 404 consecutive gastric cancer patients who underwent laparoscopic total gastrectomy (LTG) with D2 lymphadenectomy. There were 68 patients with No.10p LN dissection (No.10p group), and 336 patients without No.10p LN dissection (nNo.10p group). The surgical outcomes are compared.ResultsNo.10p LN dissection was preferentially performed in patients who were younger and had a lower BMI, concentrated and single-branched type of splenic artery, and pancreatic tail near the lower pole of the spleen. The time for No.10 LN dissection and the number of No.10 LNs were greater in the No.10p group than in the nNo.10p group. There was no No.10p LNs metastasis, and the numbers of positive No.10 LNs were similar between the two groups. The morbidity and mortality rates of the No.10p group were comparable to those of the nNo.10p group. The overall survival (OS) rates of the two groups were not significantly different (P>0.05).ConclusionsAlthough 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.
