Current perspectives on the safety and efficacy of robot-assisted surgery for gastric cancer.

Park, Sung Hyun; Hyung, Woo Jin

INTRODUCTION Robotic gastrectomy is performed worldwide as part of the treatment for gastric cancer and is associated with good clinical outcome. This review aims to describe the current issues, debates, and future directions associated with the use of robotic gastrectomy for gastric cancer. AREA COVERED Here, we review the current evidence surrounding the safety and efficacy of robotic gastrectomy, including our institutional experience. Current issues associated with robotic gastrectomy, including feasibility, perioperative outcomes, and oncological outcomes, are described. EXPERT COMMENTARY Sophisticated movements, articulating instruments, and the rapid introduction of fast-developing novel technology make robotic gastrectomy use more frequent. However, the need for well-designed prospective randomized trials is warranted.
