Abstract:
Benign tracheal strictures have been treated by repeated dilations using rigid bronchoscopy and general anesthesia. An alternative approach using conscious sedation, fluoroscopy, flexible bronchoscopy, and Savary-Gilliard esophageal dilators (Cook Endoscopy, Inc, Winston-Salem, NC) is reported. All patients undergoing dilation while awake had lesions due to inflammatory disease or lesions that were not amenable to resection. This method may be less traumatic than rigid bronchoscopy and can be accomplished on an outpatient basis without the use of general anesthesia.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
