Fluoroscopically Guided Balloon Dilation of the Esophagus

Abstract

Balloon dilation has become a common method for treating a variety of esophageal conditions. When properly performed, it is an effective procedure with a high rate of success. Fluoroscopically guided balloon dilation offers distinct advantages over endoscopically performed balloon dilation or blindly performed bougienage, as it allows for better visual control of the procedure and morbidity is low. In our experience, fluoroscopically guided esophageal balloon dilation is safe and easy to perform, provided that the operators are aware of the potential complications and the procedure is properly tailored to the patient's underlying condition. At our institution, over the course of 25 years we have performed more than 2300 fluoroscopically guided esophageal balloon dilations to treat a multitude of disorders including strictures of benign and malignant etiology, anastomotic strictures, radiation-induced strictures, tight gastric fundoplication wraps, esophageal webs and rings, achalasia, and anastomotic leaks. Over the years that we have performed the procedure, we have adapted our technique to maximize postprocedural outcomes and utilize available technology. In this article, we describe our current technique, present the various conditions amenable to balloon dilation, and emphasize modifications for each condition. We also discuss potential problems and complications that we have experienced in our practice.
