Lets the physician look inside your entire large intestine , from the lowest part, the rectum , all the way up through the colon to the lower end of the small intestine . The procedure is used to diagnose the causes of unexplained changes in bowel habits. It is also used to look for early signs of cancer in the colon and rectum. Colonoscopy enables the physician to see inflamed tissue, abnormal growths, ulcers, bleeding, and muscle spasms.

Upper Endoscopy

The procedure might be used to discover the reason for swallowing difficulties, nausea , vomiting , reflux , bleeding, indigestion , abdominal pain, or chest pain. Upper endoscopy is also called EGD, which stands for esophagogastroduodenoscopy (eh-SAH-fuh-goh-GAS-troh-doo-AH-duh-NAH-skuh-pee).

Endoscopic Retrograde Cholangiopancreatography Enables the physician to diagnose problems in the liver, gallbladder, bile ducts, and pancreas. The liver is a large organ that, among other things, makes a liquid called bile that helps with digestion. The gallbladder is a small, pear-shaped organ that stores bile until it is needed for digestion. The bile ducts are tubes that carry bile from the liver to the gallbladder and small intestine. These ducts are sometimes called the biliary tree. The pancreas is a large gland that produces chemicals that help with digestion.

Flexible Sigmoidoscopy

Enables the physician to look at the inside of the large intestine from the rectum through the last part of the colon, called the sigmoid colon. Physicians may use this procedure to find the cause of diarrhea, abdominal pain, or constipation. They also use sigmoidoscopy to look for early signs of cancer in the colon and rectum. With sigmoidoscopy, the physician can see bleeding, inflammation, abnormal growths, and ulcers.
