Flexible esophagoscopy or flexible bronchoscopy may be useful in the diagnosis of acquired tracheoesophageal fistulas (TEFs). Either or both of these procedures may be required to evaluate the anatomy of these structures and to exclude an unsuspecting mucosal lesion. The role of endoscopic procedures is especially important in localizing the acquired nonmalignant or malignant TEF.
