Barium esophagram, also known as a barium swallow, is a diagnostic imaging examination of the esophagus. It uses a contrast agent, barium sulfate, to visualize the structure and function of the esophagus, which is the muscular tube that connects the throat to the stomach.

The procedure begins with the patient drinking a liquid or swallowing a tablet containing barium. As the barium coats the lining of the esophagus, it becomes visible on X-ray images. A radiologist or technologist will then observe the barium's passage down the esophagus, taking multiple X-ray images or a fluoroscopic video. This allows for assessment of the esophagus's motility, the presence of any blockages, abnormalities in its lining, or structural changes.

Barium esophagrams are commonly used to diagnose various conditions affecting the esophagus, including dysphagia (difficulty swallowing), heartburn, chest pain, gastroesophageal reflux disease (GERD), esophageal strictures, hiatal hernias, diverticula, and esophageal cancer. It can also be used to evaluate the effectiveness of treatments for these conditions.

The procedure is generally safe, although potential side effects include constipation due to the barium. It is important for patients to inform their doctor about any recent or planned medical procedures, especially those involving the gastrointestinal tract, as barium can interfere with other tests. Patients are typically advised to avoid food and drink for several hours before the examination and to drink plenty of fluids afterward to help expel the barium from their system.
