A properly executed colonoscopy can show irritated and swollen tissue, ulcers, and polyps inside the inner lining of your large intestine. The colonoscopy procedure uses a flexible, narrow tube with a light and camera on one end, called a colonoscope or scope, to look inside the colon and rectum.

EGD or esophagogastroduodenoscopy is a test completed to examine the lining of the esophagus, stomach and initial part of the small intestine. Using an endoscope, a small flexible camera, the doctor will be able to enter your esophagus to view your stomach, esophagus and duodenum.

• Heartburn
• Black or tarry stools or vomiting blood

Capsule Endoscopy

The procedure is used to take images of your digestive track by swallowing a pill sized capsule. As the capsule travels through the digestive track, the camera will be able to take images of your digestive track, a location that is not easy to view with traditional endoscopy. A capsule endoscopy is used to identify diseases of the small intestine.

What can it help diagnose?

• Angiodysplasias
• Crohn's Disease
• Small intestinal tumors such as lymphoma, carcinoid tumor, and small intestinal cancer
