Abstract
Gastric cancer (GC) is the fifth most common cancer and fourth leading cause of cancer-related deaths worldwide. Gastrectomy with lymphadenectomy is the standard treatment for both early and locally advanced GC. Laparoscopic surgery has been widely used for decades for the treatment of benign diseases, such as cholecystectomy and appendectomy. The use of laparoscopy-assisted distal gastrectomy (LADG) for the treatment of gastric cancer was first described by Kitano in 1994. Since then, the number of gastric cancer cases treated with LADG has gradually increased. Recently, robot-assisted gastrectomy (RDG) has also been introduced in the treatment of GC. To date, several randomized control trials (RCT) have been conducted to evaluate the safety, feasibility, and efficacy of LADG and RDG in comparison to open distal gastrectomy (ODG). However, the short- and long-term oncological outcomes of LADG and RDG remain controversial and have not been fully evaluated. To optimize GC treatment, especially gastrectomy with lymphadenectomy, it is necessary to understand the characteristics of each approach before gastric cancer treatment. This review summarizes the background, current status, and future perspectives of LADG and RDG in GC treatment using RCT data.
