胃癌根治术血管鞘内、外淋巴结清扫临床结果比较分析

目的 比较血管鞘内、外淋巴结清扫对胃癌患者临床结局的影响.方法 回顾性分析1994年6月至2005年4月外科治疗的759例胃癌患者的临床资料,其中根治性切除627例,并分别采取血管鞘内淋巴结清扫(VLND组,215例)和血管鞘外淋巴结清扫(NVLND组,412例).分析比较两组不同的淋巴结清扫方法的手术时间、术中失血量、外科并发症等资料,并比较分析两组术后生存率差异.结果 根治性切除手术后5年和10年生存率比较:VLND组分别为55.4%和51.2%,NVLND组分别为39.1%和36.8%,两组差异均有统计学意义(P<0.05).VLND组中N0～N2、T2～T4、Ib～Ⅳ期胃癌患者术后5、10年累积生存率均显著高于NVLND组.而术中输血量、手术时间、手术并发症、术后并发症两组差异无统计学意义.结论 对于进展期胃癌患者,血管鞘内淋巴结清扫可提高术后生存率,不增加手术时间和术后并发症,是安全的淋巴结清扫技术.

Clinical results of vagina vasorum lymph node dissection and non-vagina vasorum lymph node dissection in gastric cancer after radical operation

Objective To evaluate and compare the results of vagina vasorum lymph node dissection (VLND) and non-vagina vasorum lymph node dissection (NVLND) in patients with gastric cancer after radical operation. Methods A total of 759 cases of evaluable patients with gastric cancer, operated from June 1994 to April 2005, were retrospectively analyzed. Of which, 627 cases underwent radical gastrectomy: 215 patients received VLND and 412 cases received NVLND. The operation time, intraoperative blood loss, operative complications and survival rate were recorded and compared between the two groups. Results The 5- and 10-year overall accumulative survival rates of VLND group and NVLND group were 55.4% and 51.2%, 39. 1% and 36. 8%, respectively (all P<0.05) . No significant differences in intraoperative blood transfusion (loss), operation time, operative complication rate was found between the two groups. The 5- and 10-year accumulative survival in patients with a tumor of phase N0-N2, T2-T4, Ib-Ⅳ in VLND groups were all significant higher than those in NVLND group. Conclusion VLND is a safe technique in advanced gastric cancer, it dose not prolong operation time or increase operative complications but improves survival.
