Transnasal balloon dilation of the esophagus.
OBJECTIVE
To describe the safety of transnasal balloon dilation of the esophagus.


METHODS
Retrospective case series.


METHODS
Two tertiary care institutions.


METHODS
All patients undergoing transnasal balloon dilation of the esophagus.


METHODS
Complications.


RESULTS
Fifty-four transnasal esophageal balloon dilations were performed in 38 patients. The mean age of the cohort was 65 years (range, 13-88 years). Twenty-nine patients were male (76%). Twenty procedures were performed using only topical anesthesia in the office setting. Seven patients (18%) were postlaryngectomy, and 15 patients (39%) had a history of head and neck radiation therapy. The upper esophageal sphincter (UES) was the most frequent dilation site (63%), followed by proximal/mid esophagus (26%), lower esophageal sphincter (LES) (7.4%), and both the UES and LES (3.7%). Indications included cricopharyngeal dysfunction, benign stricture, web, and Schatzki ring. Two procedures (3.7%) were aborted secondary to self-limited laryngospasm or gagging. There were no clinically significant complications.


CONCLUSIONS
Transnasal esophageal balloon dilation can be performed in unsedated or sedated patients with a very low complication rate. The procedure is well tolerated in 96% of patients. This technique, formerly available only through larger caliber oral gastroscopes and under sedation, allows for office-based esophageal balloon dilation in an otolaryngology practice.
