Summary

1. To evaluate the safety, simplicity and effectiveness of the gastric function (anti-reflux) preservation of the innovative "parachute-tunnel-style technique" (PTST) in laparoscopic proximal gastrectomy. 2. To investigate the correlation between anastomotic stenosis and blood supply of serosa-muscle flap,suture after esophagogastric anastomosis.(obtain objective indexes such as blood supply, healing pattern and length change of serosa-muscle flap through animal experiments)

Conditions

• Gastroesophageal-junction Cancer
• Proximal Gastrectomy
• Gastroesophagostomy

Interventions

Type	Name	Description
PROCEDURE	PTST(parachute-tunnel-style technique)for esophagogastrostomy	Suture the gastric remnant at the mark on the back wall of the esophagus.(Don't tighten the suture); Pull the esophageal stump out of the tunnel meanwhile tighten the suture and the gastric stump to close the back wall of the esophagus and the gastric stump together;Cut the back esophageal wall close to the esophageal stump,cut the front gastric wall along line B. Suture the back esophageal wall and the upper edge of the front gastric wall incision from right to left;Remove residual esophageal nail, and suture the back esophageal wall and the lower edge of the gastric incision from right to left. Suture the anterior wall of the stomach at the lower edge of the tunnel with the serosa layer at the lower edge of the front wall of the esophagus stomach anastomosis;Suture the upper edge of the tunnel with the front wall of the esophagus and the left and right lateral walls at the gastric stump suture of the original posterior wall of the esophagus. (all use 3-0 barbed suture continuously)
