"Preliminary Efficacy Analysis of C Single Flap Plasty Reconstruction After Laparoscopic Proximal Gastrectomy"

"1\. C-shaped flap creation: A 3.0 cm wide by 3.5 cm high C-shaped flap is marked on the anterior gastric wall, 1.5-2.5 cm distal to the stomach transection line. The flap is created by carefully separating the submucosa from the muscular propria using an electric scalpel, forming a left-opening flap. This flap will later be used to cover the anastomotic site. 2. Esophagogastric anastomosis: The esophagus and stomach are anastomosed intracorporeally. After continuous suturing of the posterior esophageal wall to the remnant stomach, the common opening between the esophagus and the stomach is closed. 3. Flap coverage: After anastomosis, the C-shaped flap is sutured over the anastomotic site, reinforcing it by covering both the esophageal stump and the gastric window, which helps prevent complications like leakage or reflux."

1\. Preparation of the Remnant Stomach and Esophagus: After the resection of the proximal stomach, the remaining stomach is prepared for direct anastomosis with the esophagus. The esophageal stump and gastric stump are aligned, typically without additional modifications to the gastric wall. 2. End-to-End or End-to-Side Anastomosis: The esophagus is directly connected to the remnant stomach, either in an end-to-end or end-to-side fashion, using a stapler or manual suturing techniques.
