What is the test?

This procedure uses x-rays and an endoscope to see inside your digestive system and diagnose problems such as tumors, gallstones, and inflammation in your liver, gallbladder, bile ducts, or pancreas.

Avoid eating or drinking anything for eight hours before the test because it needs to be done on an empty stomach.
