Background: To compare the surgical and long-term survival outcomes of laparoscopic and open total gastrectomy (OTG) for locally advanced gastric cancer (AGC).
Methods: We retrospectively evaluated 308 and 900 patients in pathological locally AGC who underwent laparoscopic total gastrectomy (LTG) or OTG between June 2008 and December 2014. We compared surgical and long-term outcomes between the two groups using propensity score matching method.
Results: The LTG group showed a longer operation time (261.42 vs. 171.00 min, P = 0.001), less blood loss (185.47 vs. 217.84 ml, P = 0.000), earlier time to first flatus (3.47 vs. 4.12 days, P = 0.000), earlier time to start liquid diet (3.76 vs. 4.27 days, P = 0.000), and shorter postoperative hospital stay (7.56 vs. 8.22 days, P = 0.007). The overall complication rate was 15.2% in the LTG group and 17.2% in the OTG (P = 0.503). No significant difference was observed in overall survival (OS) and disease-free survival (DFS) between LTG and OTG (60.5% vs. 57.1%, P = 0.337; 57.4% vs. 54.4%, P = 0.341).
Conclusions: Compared to OTG, LTG provides surgical benefits and comparable survival outcomes for patients with locally AGC.
