135 Background: The aim of this study is to investigate the oncologic outcomes as well as short-term outcomes of laparoscopic distal gastrectomy compared with open distal gastrectomy for advanced gastric cancer using propensity-score matching analysis. Methods: A total of 384 patients underwent distal gastrectomy for advanced gastric cancer from July 2006 to November 2016. Data on short- and long-term outcomes were collected prospectively and reviewed. Propensity-score matching was applied at a ratio of 1:1 comparing the laparoscopic distal gastrectomy (LDG) group and open distal gastrectomy (ODG) groups. Results: The LDG group showed longer operative time than the ODG group. However, resumption of diet and length of hospital stay were shorter in the LDG group than in the ODG group (4.7 vs. 5.6 days, p= 0.049 and 9.6 vs. 11.5 days, p= 0.035, respectively).The extent of lymph node dissection in the LDG group was more limited than in the ODG group ( p= 0.002), although there was no difference in the number of retrieved lymph nodes between the two groups. The 3-year overall survival rates were 98% and 86.9% ( p= 0.018), whereas the 3-year recurrence-free survival were 86.3% and 75.3%, p= 0.259) in the LDG and the ODG groups. Conclusions: Laparoscopic distal gastrectomy is safe and feasible for advanced gastric cancer in terms of earlier recovery after surgery and long-term oncologic outcomes.
