The patient swallows a capsule containing a tiny camera. The camera transmits images to a video monitor as the capsule passes through the digestive tract. This procedure is designed to examine the small intestine, but it also allows the doctor to examine the rest of the digestive tract.
Endoscopic Retrograde Cholangiopancreatography (ERCP)
Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure that combines upper gastrointestinal (GI) endoscopy and X-rays to treat problems of the bile and pancreatic ducts. ERCP is also used to diagnose problems, but the availability of non-invasive tests such as magnetic resonance cholangiography has allowed ERCP to be used primarily for cases in which it is expected that treatment will be delivered during the procedure.
Endoscopic Ultrasound (EUS)
After spraying a solution to numb the patient’s throat, the doctor inserts an endoscope—a thin, flexible, lighted tube—down the throat, through the stomach and into the small intestine. The doctor turns on an ultrasound attachment to the scope that produces sound waves to create visual images of the pancreas and bile ducts.
Small-bowel enteroscopy with a spiral overtube (a spiral endoscopy). This is an innovation that’s basically an overtube that is applied through a standard enteroscope. The endoscopy is evaluated by pushing down the endoscope into the duodenum and then, by a clockwise rotation of this spiral overtube in a putting-a-screw-into-a-hole type of approach, allows the bowel to be placated over the enteroscope and allows deep enteroscopy.
