Abstract
Management of esophago-airway fistulas (EAF) and obstructions often involves therapy with esophageal and/or airway stents. We present a unique approach for the management of EAF and obstructions with simultaneous upper endoscopy and bronchoscopy (two scopes inserted simultaneously through the mouth). The aim is to assess the efficacy and safety of a simultaneous dual scope approach for management of EAF and obstructions. The endoscopy database at the University of Florida was reviewed from October 2007 to April 2012 to identify adult patients who had undergone simultaneous upper endoscopy and bronchoscopy for EAF and obstructions. Medical records were reviewed for demographics, indication, pathology, imaging, simultaneous endoscopic and bronchoscopic findings/maneuvers, outcomes, and adverse events. Outcomes assessed included: (i) technical success, (ii) fistula occlusion, (iii) dysphagia score, and (iv) adverse events. Thirteen patients with EAF and/or obstruction underwent simultaneous dual scope endoscopy. Dual scope procedures were technically successful in 12/13 (92%) patients. Dysphagia score improved from three to one in both patients with dysphagia without EAF. Fistula occlusion was observed in 7/10 patients (70%) with EAF. With this technique, stents were placed accurately without airway compression, migrated esophageal stents extracted from the tracheal lumen without trauma, and tracheal stents not displaced during esophageal manipulations. EAF not otherwise apparent were identified in two patients. Adverse events occurred in 2/13 (15%) patients, and 5/13 (38%) patients died from advanced cancer during follow up (mean 4.1 months, range 1-8 months). Simultaneous dual scope (two scopes inserted through the mouth at the same time) therapy of EAF and obstructions is feasible, effective, and safe, and may develop to be the preferred approach for the management of complex esophago-airway diseases.
