Endoscopies look inside your digestive tract to diagnose or treat a disease. At Essentia Health, you gain access to doctors with special training in therapeutic endoscopy. Trust us to help you feel comfortable and get results from your care.

What's an Endoscopy?

An endoscopy is a nonsurgical procedure used to examine the inside of your digestive tract. During the procedure, your doctor will slide an endoscope—a thin, flexible tube with a light and camera attached to it—into your mouth and down your esophagus (swallowing pipe). Before your procedure, you’ll receive medicines to relax you and prevent throat pain.

Upper Endoscopy

An upper endoscopy allows your doctor see the inside of your esophagus, stomach, and first part of the small intestine. This test checks for problems that cause belly pain, nausea, vomiting, trouble swallowing, or bleeding.

Your care team will provide you with specific directions on how to prepare for an upper endoscopy.

Endoscopic Ultrasound

During an endoscopic ultrasound, a thin tube sends out sound waves that create pictures of the inside of your digestive tract. This test can find the cause of belly pain and look at the pancreas, bile duct, and gallbladder.


During an ERCP, a thin tube is used to inject dye into the bile ducts in your digestive tract so they show up on X-rays. This helps your doctor examine or treat gallstones, blockages, tumors, and other conditions.

Capsule Endoscopy

For a capsule endoscopy, you simply swallow a small pill with a tiny camera inside it. The camera sends images of the inside of your digestive tract to a recorder worn around your waist. The doctor will look at the images on a computer after the pill completes its journey through your body.
