Anti-reflux effects of a novel esophagogastric asymmetric anastomosis technique after laparoscopic proximal gastrectomy

Figure 2 Computer simulations of esophagogastric asymmetric anastomosis mechanisms using the finite element method. A: Adobe Illustrator was used to draw the curve of the gastric section; B: The valve-like structure of the folded gastric wall and the posterior wall of the lower esophagus move to the upper left side like a lever at the site of anastomotic stoma, causing tightening of the anastomotic stoma; C: Because of the increased pressure in the gastric cavity and the expansion of the gastric fundus, the folded gastric wall and the esophageal wall moved to the left, which effectively tightened the anastomotic stoma.
