Despite a wider application of robot to radical esophageal resection in recent years, the process of esophagogastrostomy is relatively complicated. Current commonly-applied clinical techniques in digestive tract reconstruction include end-to-end anastomosis, end-to-side anastomosis, and side-side anastomosis. The main methods are divided into manual and mechanical anastomosis. And the main instruments applied include circular stapler and linear stapler. Different technologies vary in advantages and restrictions and selecting the technique in esophageal operation depends on the situation of the tumor and the operator’s preference. The improved anastomosis techniques and the updated anastomosis instruments effectively lower the incidence of complications after esophagogastrostomy. However, there are still great difficulties in carrying out a safe and efficient reconstruction of the digestive tract during the operation. Scholars over the world have been working hard on it and have made modified various reconstruction techniques. Different technologies vary in advantages and restrictions and the choice of the technique depends on the situation of the tumor and the patient’s preference. There is no unified consensus on the choice of the technique. This paper introduces the research progress in robot’s assisted esophagogastrostomy from two aspects including the technique and method of anastomosis.
