Abstract:
Objective To evaluate No.16a2b1 lymphadenectomy for D2 gastrectomy of advanced gastric cancer.Methods In this study,we retrospectively analysed the data of 100 patients with advanced gastric cancer from April 2004 to April 2005.All the patients were in stage T3-4.50 patients underwent D2 plus No.16a2b1 lymphadenectomy while the other 50 patients underwent standard D2 operation.Results The metastatic rate of No.16a2b1 lymph node was 18％ ;The bleeding volume,operation time,postoperative intestinal function recovery time and the incidence of postoperative complications between D2 plus No.16a2b1 lymphadenectomy group and standard D2 operation group were [(351 ± 121) ml vs.(305 ±-105) ml,t=2.03],[(192±50) vs.(172±40),t=2.22],[(5 ±2) days vs.(4±-2) days,t=3.33],and [10％ (5/50) vs.8％ (4/50)] respectively.All differences were not statistically significant (P ＞0.05).While 5 year survival rates were 24％ (12/50) vs.6％ (3/50) respectively,the difference was statistically significant (P ＜ 0.05).Conclusions No.16a2b1 lymphadenectomy is necessary,feasible and prolongs survival for advanced gastric cancer patients,especially in stage T3 and T4 undergoing D2 operation.
