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

Figure 4 Abdominal computed tomography (oral CO₂ powder). A: coronal surface: The valve-like structure can be seen at the anastomosis, tightly closed; B: Sagittal plane: The gastric cavity is inflated, seeing the anastomotic valve-like structure with gear sample occlusion and a small amount of gas overflow in the esophagus.
