Current perspective and review of literature on robotic gastrectomy and oncological outcomes

Gastric cancer (GC) is a malignant tumour that develops in the gastric epithelial tissue. It is now one of thecommonest reported malignant tumours worldwide. Gastrectomy is the most effective GC treatment. The introduction of minimally invasive gastrectomy was done over thirty years ago to reduce related burden among patients. Nowadays, minimally invasive gastrectomy is becoming more widely accepted as a viable treatment option for gastric cancer. Although recent research implies that robotic application has some advantages over traditional laparoscopy, the significance of robotic surgery in clinical practice is yet unknown. However, most studies revealed that robotic gastrectomy (RG) and laparoscopic gastrectomy (LG) have analogous oncological results in gastric cancer treatment, and general inferences on whether RG offers greater benefit over LG are still tough to draw. Furthermore, to assess the possible advantages and hazards related to RG for gastric cancer, policymakers and surgeons require a complete evaluation of the strength and depth of scientific data. Therefore, in this narrative literature review, we aimed to describe and delineate the present perspective of RG and its oncological outcome in gastric cancer subjects. Also, we intended to provide surgeons with a revised as well as updated summary of present evidence and to bring surgical practice more in line with present evidence.
