Esophageal Dilation and Injection
Esophageal dilation (also known as stretching) can be performed with rigid dilators or balloon dilators. Rigid dilators are typically used in the operating room under general anesthesia. Balloon dilation can be done in the office with TNE, or under light sedation in a procedure suite. Both techniques are excellent for strictures, Schatzki’s rings, webs, and cricopharyngeal dysfunction.
Esophageal Injection with Botulinum Toxin
For problems with relaxation of the lower esophageal sphincter or upper esophageal sphincter, a long needle can be used through the TNE (link) scope in the office to inject botulinum toxin. Botulinum toxin temporarily paralyzes muscles, lasting about 3-6 months.
