How can specific types of endoscopy help to diagnose Crohn’s disease and ulcerative colitis (UC)?

ANSWER

Your doctor can use specific types of endoscopy to help diagnose Crohn’s disease and ulcerative colitis (UC) because it can:

  • Examine lower part of your large intestines. This test is called a sigmoidoscopy.
  • Look at your entire large intestine. This is a colonoscopy.
  • Check the lining of the esophagus, stomach, and duodenum. This is an EGD (esophagogastroduodenoscopy).
  • Look at your small intestine using a pill-sized camera. This is often called pill, or capsule, endoscopy.
  • See the bile ducts in the liver and the pancreatic duct. This test is called ERCP (endoscopic retrograde cholangiopancreatography).
