The history and use of the timed barium esophagram in achalasia, esophagogastric junction outflow obstruction, and esophageal strictures.

Abstract

Background: Dysphagia is one of the most common complaints that gastroenterologists encounter in the outpatient setting. To evaluate this common complaint, patients are often sent for a barium esophagram, a test that is widely available, inexpensive, and easy to perform. This simple test provides a reliable method to evaluate esophageal anatomy and structural abnormalities.

Purpose: This narrative reviews the history of the development and validation of the timed-barium esophagram (TBE), along with its strengths and limitations, and discusses its use in the pre- and posttreatment assessment of patients with achalasia, esophagogastric junction outflow obstruction (EGJOO), and esophageal strictures. Providing excellent anatomic detail of the esophagus and an accurate assessment of esophageal emptying, over time, the TBE has become part of the standard workup in our Swallowing Center for patients with dysphagia.
