Using the supercharge technique to additionally revascularize the gastric tube after a subtotal esophagectomy for esophageal cancer

Background Maintaining sufficient blood flow to the gastric tube after a subtotal esophagectomy for esophageal cancer is crucial for decreasing esophagogastric anastomotic leakage. Methods After subtotal esophagectomy for esophageal cancer, the supercharge technique was performed in 21 esophageal reconstruction patients to additionally revascularize the gastric tube using the splenic artery and vein, external carotid artery, and internal jugular vein. Operative results of the supercharge group were retrospectively compared with those of the control group (patients not receiving the technique). Results Both operation time and operative blood loss in the supercharge group were significantly longer and larger than those of the control group. However, the incidence of anastomotic leakage was significantly lower in the supercharge group than in the control group. Conclusion This practical supercharge technique reduces leakage during esophageal anastomosis.
