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

ABSTRACT

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. CONCLUSIONS: VLND is a safe technique in advanced gastric cancer, it dose not prolong operation time or increase operative complications but improves survival.
