Case report: Tracheoesophageal Fistula and Respiratory Failure After the Placement of an Esophageal Metallic stent. Treatment Using a Dumon Stent We have seen major technological advances in the endoscopic treatment of patients with inoperable cancer in the past years. This situation has allowed improve the quality of life of many patients, but we have also seen new clinical syndromes associated with the use of these resources. For example, esophagic stents are invaluable tools in the pallia- tive treatment of patients with esophageal cancer, but unfortunately these are not free of complications, especially the new self-expandable metallic stents. Metallic stents produce enormous radial forces and these devices may develop extrinsic tracheal compression with progressive respiratory failure. We present a case of respiratory distress and hemoptysis secondary to the placement of a self-expanding esophageal stent and treatment of this complication with Dumon stent
