Why a Colonoscopy:
It is done to view the rectum and colon, using a colonoscope, which is a long, flexible tube with a camera on the end. Colonoscopy is done to check for colon cancer and other problems in the large intestine, as well as to treat and remove polyps. A biopsy can be done during a colonoscopy to look for microscopic evidence of disease.
Upper GI Endoscopy/EGD What Can I Expect?
An upper GI endoscopy uses an endoscope to look at, diagnose and treat issues in the esophagus, stomach and start of the small intestine. A biopsy can be done during this procedure to look for microscopic evidence of disease.
ERCP (Endoscopic Retrograde Cholangio Pancreatography):
Endoscopic retrograde cholangiopancreatography (ERCP) is a critical, life-saving and highly technical endoscopic procedure. The procedure helps to diagnose and treat problems in the bile duct and pancreatic ducts, such as stones, narrowing (called strictures) and blockages. ERCP uses an endoscope to look at, and inject dye into, the duodenum, pancreas, bile ducts and gallbladder.

An endoscopic ultrasound (EUS) uses an endoscope (a long, flexible tube with a camera on the end) to view the throat, stomach and small intestine. An ultrasound attachment is used in conjunction with the scope and produces sound waves to create visual images of the pancreas and bile ducts. An EUS can be used to view the upper or lower GI tract.
