Barium Swallow . Introduction

A barium swallow is a test used to determine the cause of painful swallowing, difficulty with swallowing, abdominal pain, or unexplained weight loss.

These problems can be detected with a barium swallow:

Narrowing of the esophagus (the muscular tube between the back of the throat and the stomach) Disorders of swallowing

Abnormally enlarged veins in the esophagus that cause bleeding Ulcers Tumors Polyps (growths that are usually not cancerous, but could be precancerous)

To Prepare: Do not eat or drink anything, including water, after midnight before the test.

If you are pregnant, or think you might be, tell the staff before the x-ray is taken. a (

Anatomy: When the esophagus is empty , the mucosa coat is thrown into three or four straight longitudinal folds

1.Oesophageal Varices They appear inside the oesophagus and occasionally they occur in the stomach. Varices develop when most of the normal liver tissue has been

replaced by scar tissue. Because the scar tissue pushes upon the veins in the liver, blood cannot flow normally through the veins. 1.Oesophageal Varices

1.Oesophageal Varices What is the radiographic appearance ? There are multiple submucosal filling

defects in a barium filled esophagus in AP view. 2. Achalasia Achalasia is a disease of esophagus .

The term achalasia means "failure to relax" and refers to the inability of the lower esophageal sphincter (a ring of muscle situated between the lower esophagus and the stomach) to open and let food pass into the stomach. As a result, patients with achalasia have

difficulty in swallowing food. 2. Achalasia 2. Achalasia Lower Esophagus

Proximal Dilatations Distal Narrowing

What is the radiographic appearance ? Dilated smooth outlined barium filled esophagus with narrow tapering lower end of the esophagus with smooth outline and absence of fundal gas in stomach. .

Is a blind sac (pouch) that branches off the cervical esophagus. It is the most common type of esophageal diverticulum. 3. Zenker's diverticulum (ZD)
