Minimally invasive surgery in advanced gastric cancer

Since Dr. Kitano introduced laparoscopic distal gastrectomy for early gastric cancer in 1994, there have been remarkable advances in minimally invasive surgery (MIS) for gastric cancer, including robotic surgery. With the efforts of many clinical researchers and consenting patients, medical knowledge and evidence for laparoscopic surgery in gastric cancer have accumulated. Although many gastric surgeons are comfortable with the clinical application of laparoscopic surgery for early gastric cancer, the adoption of MISs for advanced gastric cancer remains controversial. In this review article, we describe the current status and evidence of MIS from an evidence‐based medicine viewpoint and explore the feasibility and effectiveness of MIS for advanced gastric cancer in the real world.
