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

Figure 1 Critical design features of the esophagogastric asymmetric anastomosis technique. A: (1) The diameter of the esophagus and the incision size of the residual gastric anterior wall are asymmetric; and (2) The length of the two sides of the lower esophagus is asymmetrical; The points a/b/c/d shows the corresponding points of asymmetric anastomosis respectively between esophagus and residual stomach; B: Asymmetry of the longitudinal section (or sagittal surface) of the esophagus and the residual stomach after anastomosis; C: After anastomosis, the seromuscular layer of the residual stomach and esophagus is asymmetrically sutured; D: The sagittal plane of esophagogastric asymmetric anastomosis: Showing the suture point of the asymmetric anastomosis; the red arrow indicates a flap structure formed by the folded gastric wall in the gastric cavity.
