How to effectively repair esophageal fistulas, caused by esophageal perforation, rupture and anastomotic leakage after esophagectomy has always been a key problem for the digestive surgeon. Although there are many clinical treatment methods, the therapeutic effect is still completely unsatisfactory, especially when severe mediastinal purulent cavity infection is associated with the esophageal fistula. In recent years, foreign centers have promoted a new minimally invasive endoscopic treatment technology to repair the esophageal fistula, endoscopic vacuum-assisted closure therapy, with significantly curative effect. In this article, we will review the specific operation, advantages and disadvantages, as well as the clinical efficacy of endoscopic vacuum-assisted closure therapy in treating the esophageal fistulas, to provide a new therapeutic technique for esophageal fistulas and expand the new field of minimally invasive endoscopic therapy.
