Laparoscopic gastrectomy is a widely accepted gastric cancer treatment option, especially for early gastric cancer, after its introduction by Kitano et al. The Japanese JCOG 0912 study reported similar complication rates after laparoscopic and open distal gastrectomy for early gastric cancer, whereas the Korean KLASS-01 study showed that laparoscopic distal gastrectomy was associated with a lower overall postoperative complication rate. The KLASS-01 study also demonstrated non-inferiority of laparoscopy over open distal gastrectomy in long-term survival. Many retrospective studies show that laparoscopic gastrectomy for advanced gastric cancer is safer and more feasible than open gastrectomy. However, most of these studies are limited due to the small sample size. In 2008, we started the first prospective, single-arm, phase II trial of laparoscopic gastrectomy for advanced gastric cancer. We demonstrated the safety and technical feasibility of laparoscopy for advanced gastric cancer with acceptable morbidity and mortality. A recent Chinese CLASS-01 trial showed similar 3-year survival between laparoscopic and open surgery. The long-term outcome of KLASS-02 concluded that laparoscopic distal gastrectomy with D2 lymphadenectomy is similar to open surgery in terms of recurrence-free survival in patients with locally advanced gastric cancer. In this session, we would like to introduce minimally invasive surgery in the field of gastric cancer and share the experience of Seoul National University Bundang Hospital.
