Abstract
BackgroundThis study aimed to compare the short-term and long-term outcomes of laparoscopic gastrectomy (LG) and open gastrectomy (OG) for gastric cancer in a tertiary referral center in Hong Kong. MethodsTwo hundred and ninety-four consecutive patients with gastric cancer who underwent radical gastrectomy with curative intent between January 2008 and December 2015 were analyzed. Data was prospectively collected and reviewed. Propensity score matching was applied at a ratio of 1:1 to compare the OG and LG groups. ResultsAfter propensity score matching, operation duration (294.7 vs 231.8min, P < 0.01) was significantly longer while estimated blood loss (191.6 vs 351.0 ml, P = 0.01) was significantly less in LG group compared with OG. There were no significant differences in postoperative complications and mortality between LG and OG groups (postoperative complication rate, 35.2% vs 40.7%, P = 0.69; 90-day mortality rate, 1.9% vs 3.7%, P = 1.00). Three-year OS and 3-yr DFS of patients who underwent LG was not inferior to that of patients who had OG (P = 0.34; P = 0.51). However, there were significantly more peritoneal recurrences among the OG group than LG group (P < 0.01). ConclusionsLG has comparable outcomes for gastric cancer, even in advanced tumors. We could appropriately increase the proportion of laparoscopic gastrectomy for gastric cancer.
