To investigate the clinical efficacy and prognosis of laparoscopic assisted radical gastrectomy of D2 for advanced gastric cancer.

The 73 patients with advanced gastric cancer and treated in our hospital from 2011 to 2013 were retrospectively analyzed . Patients were divided into open group (34 cases) and laparoscopic group (39 cases) according to different surgical methods. SPSS 24.0 statistical software package was used for data analysis. Intraoperative and postoperative indicators were expressed by (±s), and compared with t test. The postoperative complications were compared with chi square test. Postoperative survival was compared with Kaplan-Meier method. The difference of P<0.05 was statistically significant.

Compared with the open group, the operative time of the laparoscopic group was significantly increased (P<0.05), and the intraoperative blood loss was significantly reduced (P<0.05). The length of stay in the laparoscopic group was significantly lower (P<0.05). The average survival time of the laparotomy group was (53.4 + 4.3) months, and the 1, 3 and 5 year survival rates were 94%, 69.8% and 63.7% respectively. The mean survival time of the endoscopic group was (50.9+ 4.6) months, 1, 3, and 5 years survival rate 92.3%, 55.4%, 50.2%. There was no significant difference in average survival time and cumulative survival rate between the two groups (F=0.180, P=0.672).

Laparoscopic D2 radical gastrectomy has satisfactory curative effect. The postoperative five year survival rate is similar compared with open surgery, and the intraoperative blood loss and postoperative hospital stay were shorter. It is safe and feasible and worthy of clinical promotion.
