Application of a New Surgical Technique in Proximal Gastrectomy: a Prospective, Multicenter Randomized Controlled Study

"This is an innovative surgical method applied in proximal gastrectomy. By adding anti reflux structures such as false gastric fundus and false cardia on the basis of esophageal residual gastric anastomosis, the goal of anti reflux is achieved, while maintaining normal physiological channels and fully utilizing residual gastric function, reducing the difficulty of proximal gastrectomy surgery"

This is a traditional surgical method that has been widely used in proximal gastrectomy. After disconnecting the proximal stomach, performing Roux-en-Y anastomosis of the esophagus and jejunum firstly, followed by lateral anastomosis of the residual stomach and jejunum. Previous studies have confirmed its safety and effectiveness, but there are also issues of gastric channel disuse and high missed detection rate of residual stomach.
