About this study
Retrospective chart review of UCDMC patients who have undergone esophageal or tracheal balloon dilation to record data including age, gender, diagnosis pre-and post-procedure eating assessment tool, esophagoscopy findings, tracheobronchoscopy findings, and pre-and post-procedure videofluoroscopic findings.
Read the detailed description
Dilation of the esophagus is performed for strictures, webs, and rings at all levels of the esophagus. Dilation of the trachea is performed for subglottic and tracheal stenosis. Radial expansion balloons have been developed by Bost Scientific Corporation for the purpose of dilating the esophagus and trachea through flexible esophagoscopies. These sequential controlled radial-expansion balloons can be introduced via a guide wire through the working channel of a 5.1 mm transnasal esophagoscope. Traditionally, otolaryngologists have performed esophageal and tracheal dilation per oral under general anesthesia. This technique allows the procedure to be performed in the office, sparing the patient the risk of anesthetics. The purpose of this study is to review the UCDMC experience with esophageal and tracheal balloon dilation using the transnasal esophagoscope.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jun 2015.
