What method is most commonly used to diagnose Zenker's diverticulum?

1. CT scan

2. Upper endoscopy

3. Barium swallow

4. Ultrasound

The correct answer is: Barium swallow

Zenker's diverticulum is an esophageal condition characterized by the formation of a diverticulum, or pouch, in the pharyngeal region, leading to swallowing difficulties and potential aspiration. The most commonly used method for diagnosing Zenker's diverticulum is a barium swallow study (also known as a barium esophagography). This technique involves the patient swallowing a barium-containing liquid, which coats the esophagus and allows for clear visualization of any abnormalities on X-rays. The barium swallow test provides valuable insights not only into the presence of the diverticulum but also into the functional aspects of swallowing and how the diverticulum affects the esophagus. It helps in assessing the size and location of the diverticulum, as well as in identifying any associated esophageal motility disorders. While other imaging techniques, such as CT scans or upper endoscopy, can provide additional information about esophageal conditions, the barium swallow remains the primary diagnostic tool due to its effectiveness in visualizing the diverticulum and assessing swallowing function in a comprehensive manner.
