Minimally Invasive Gastric Surgery.

The incidence of gastric cancer is increasing in the United States, particularly for various subtypes as well as presenting in earlier states. Such changes have allowed various centers to increasingly offer less invasive approaches to the treatment of gastric cancer, namely laparoscopic and robotic techniques. Minimally invasive gastrectomy has been suggested to have similar oncology outcomes compared to open procedures. In the last two decades, large retrospective and a series of randomized trials evaluated the role of minimally invasive gastrectomy for early gastric cancer, distal gastrectomy, total gastrectomy and advanced gastric cancer. As the experience with emerging technologies such as robotic assisted gastrectomies increases, the indications for minimally invasive surgery will likely expand.
