[Evaluation of robotic gastrectomy for gastric cancer based on the current evidence]

Surgical modality undoubtedly has been developing rapidly resulting from the improvement of minimally invasive approach and instruments. Robotic gastrectomy for gastric cancer, as one of the most common performed operations worldwide, is playing a key role in maximizing potential benefits for both patients and surgeons. Most studies have demonstrated its satisfactory short-term outcomes including fast postoperative recovery course and similar oncological adequacy, while followed by several disadvantages or pitfall such as longer operation time, relatively high costs, and uncertain long-term outcome. However, the role of robotic gastrectomy is still controversial. This article is a review about robotic gastrectomy for treating gastric cancer based on the current evidence in terms of technology, application, clinical trials, and future prospects.
