Upper GI Series: Barium Swallow

2.9K views01:24 min

A barium swallow is a diagnostic medical imaging procedure that uses barium sulfate to visualize and examine the upper GI tract, including the esophagus, stomach, and duodenum.

It identifies esophageal motility disorders, stricture, perforation, neoplasm, and hiatal hernia.

Patient preparation includes an eight-hour NPO status and prohibiting smoking after midnight to prevent increased gastric secretions.

Before the procedure, explain the process, including duration, barium sulfate mixture consumption, and the various radiographic positions. Also, instruct the patient to remove metal items such as jewelry and dentures from the radiograph field.

During the procedure, the patient consumes a barium liquid that appears bright white on X-rays.

Fluoroscopy is employed to observe the real-time movement of barium through the GI tract, and multiple X-rays are captured to gather comprehensive information.

Post-procedure instructions include drinking plenty of fluids, unless contraindicated, to eliminate the barium.

Provide cathartics as prescribed. Inform the patient that stools will be chalky and light-colored for 24-72 hours.

The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.

Purpose and Procedure

Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky consistency. This material appears bright white in X-rays, enabling the capture of detailed images of the upper GI tract. The examination can involve either X-ray images or fluoroscopy. Fluoroscopy provides real-time video X-ray imaging, particularly useful for observing dynamic processes such as swallowing and the peristalsis of the esophagus and stomach.

Indications

The barium swallow is commonly ordered for patients experiencing symptoms like difficulty swallowing (dysphagia), reflux, unexplained weight loss, abdominal pain, or persistent vomiting. It can diagnose conditions like gastroesophageal reflux disease (GERD), hiatal hernias, esophageal strictures, and certain tumors.

Preparation and Considerations

Patients must fast after midnight before the test and are advised to remove any radiopaque objects, such as jewelry or dentures. They should inform healthcare providers of any contraindications like intestinal obstruction or pregnancy, due to the potential risks of radiation exposure.

Enhanced Examination Techniques

In some cases, additional substances may be added to the barium solution to enhance the examination, such as a double-contrast technique involving gas to more clearly outline the inner surface of the digestive tract.

Post-Procedure Care

After the procedure, patients should ensure they stay adequately hydrated to remove the barium unless specific contraindications are present. Patients should take the prescribed cathartic and inform their physician if they do not expel the barium within 2 to 3 days. It is normal for stools to appear chalky and light-colored for 24 to 72 hours after the test. Although the barium swallow is generally safe, patients should address any concerns with their healthcare team, especially regarding radiation exposure and its risks. Healthcare providers must carefully balance the advantages of the examination with its potential risks to ensure patient safety and well-being.
