Four benign esophagorespiratory fistulas, three secondary to granulomatous disease and one presumed to be congenital, have been diagnosed in adults at the authors' institution in the past year. The patients had symptoms of chronic or recurrent pulmonary infections, and two experienced coughing after swallowing. Chest radiographs demonstrated refractory consolidation, with or without cavitation and frequently accompanied by an air-distended esophagus. Barium studies were diagnostic. All patients responded well to antibiotic and surgical therapy.

Background And Objective: Esophagorespiratory fistulas (ERFs) are pathologic communications between the esophagus and respiratory tract that may be congenital or acquired, and benign or malignant. ERFs can lead to significant respiratory compromise and increased mortality through recurrent respiratory infections. As the condition spans multiple organ systems, ERFs pose unique diagnostic and management challenges to pulmonologists, gastroenterologists, and thoracic surgeons.

Objectives: A stent is a mesh tube inserted into a natural passage in the body to prevent disease induction. Self-expandable esophageal nitinol stents such as SX-ELLA Stent Esophageal HV (HV Stent Plus) can be indicated for palliation of malignant esophageal strictures, for the treatment of benign esophageal strictures that are refractory to standard therapy and for the treatment of esophago-respiratory fistulas. A silicone-stent coating is used for tumor in-growth prevention and esophago-respiratory fistula occlusion.

Tracheoesophageal fistulas (TEFs) have traditionally been managed surgically, but the endoscopic approach is widely performed as a less invasive alternative. Different closure techniques have been proposed with inconsistent results. An over-the-scope clip (OTSC) appears to be a reasonable option, but long-term results have not been well defined.

Background: Nonmalignant esophago-respiratory fistulas (ERF) are frightening clinical situations, involving surgery with high morbi-mortality rate. We described the endoscopic management of benign ERF. The aim of the study was to describe outcomes of endoscopic treatment of nonmalignant ERF and to analyze factors associated with its success.

Background And Aims: Esophagorespiratory fistulas (ERF) are a devastating complication of benign and malignant etiologies. ERF are associated with high mortality, short survival, and poor quality of life. We performed a multicenter analysis of patients with ERF undergoing endoscopic treatment.
