Summary
Brief summary (as posted)
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)

- description
- Standard procedure: Patient placed in a supine position and proximal gastrectomy performed under general anesthesia. 1. Lymph node dissection 2. Cut the esophagus 3. Gymnosis of gastric curvature greater and gastric curvature lesser 4. The specimen removed from the stomach(5cm away) 5. Preparation of serosa-muscle flap: Mark two straight lines, A and B, about 3cm long, with methylene blue on the anterior wall of the stomach about 2cm and 6cm from the gastric stump. The electrocoagulation and cutting power of the electrotome were adjusted to 10 watts, and the serosa-muscle layer of the gastric wall was cut along the marked line with the electrotome. With the help of the assistant, the surgeon separated the gastric parietal serosa-muscle layer from the submucosa along line B to line A. When the dissociation reached the middle point of the tunnel, it should be dissociated along line A to line B, completely dissociated the gastric parietal serosa-muscle layer from the submucosa.
