ABSTRACT
Objective To explore the feasibility and clinical outcome of laparoscopy-assisted gastrectomy with D2 dissection by comparing the efficacy of open surgery on radical gastrectomy with D2 dissection for gastric cancer patients. Methods The patients with gastric cancer from October 2008 to August 2013 were divided into two groups according to the different surgical methods. Among them, 175 patients underwent laparoscopic surgery (laparoscopy-assisted surgery group, Group L), and 163 patients underwent laparotomy surgery (open surgery group, Group O). The number of lymph nodes dissected, postoperative recovery, complications, mortality and survival rate of the two groups were compared and analyzed. Results There was no significant difference in the number of lymph nodes resect between the two groups [Group L and Group O: (26.3 ± 13.9) vs (26.8 ± 10.2), t = -0.40, P = 0.684]. Compared with open surgery, the laparoscopy-assisted surgery showed significantly less intraoperative blood loss and quicker recovery of gastrointestinal function. The postoperative hospitalization time of laparoscopic group was less than that of laparotomy group, the difference was statistically significant (P < 0.05). No significant difference was found in 3-year survival rate between the two groups (Group L vs Group O: 92.00％ vs 92.63％, P = 0.262). Conclusions Compared to open surgery, laparoscopic gastrectomy is safer and has quicker postoperative recovery. There is no statistical difference in the number of resect lymph nodes between lapamscopic and open gastrectomy.
