Objective:
To describe the safety of transnasal balloon dilation of the esophagus.
Design:
Retrospective case series.
Setting:
Two tertiary care institutions.
Patients:
All patients undergoing transnasal balloon dilation of the esophagus.
Main Outcome Measure:
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.
