AbstractAnastomotic leakage after radical esophagectomy is mostly caused by the hypoxia and high tension at the esophagogastric anastomotic site. Here, we introduce a new surgical technique, 'Angleplasty,' to enable the tensionless anastomosis at a highly oxygenic site of gastric conduit. In short, the seromuscular layer is cut for a perpendicular direction against a lesser curvature at a gastric angle and the gastric wall is carefully divided between the muscular and submucosal layers for longitudinal direction for 4-5 cm in length. Then, the wound is closed with seromuscular sutures for longitudinal direction. With this maneuver, the lesser curvature of the gastric roll is significantly elongated and the anastomosis site of the gastric conduit can be moved more distal on the greater curvature of the stomach where it is expected to receive more oxygen supply. This technique takes only several minutes, but provides highly favorable conditions for esophagogastric anastomosis and thus is clinically useful to reduce the risk of anastomotic leakage after esophagectomy.
