ERCP
ERCP is a complex procedure involving the examination of the bile ducts that drain the liver. A special flexible digital camera called a duodenoscope is passed just beyond the stomach into the duodenum (small bowel). Here, a fine guidewire together with a thin plastic tube is guided into the ampulla where the bile duct drains into the duodenum. X-ray dye is then injected into the bile duct and X-ray images are taken to highlight the bile ducts. A small cut is made at the ampulla to allow for further therapy. This may include removal of gallstones from the bile duct, placement of a stent or biopsy.

Endoscopic Ultrasound (EUS)
EUS is a special test that allows for an ultrasound examination to be conducted from within the oesopaghus, stomach or duodenum. Similar to a gastroscopy, the EUS scope is passed into the proximal digestive tract. At the tip of the scope, however, is a miniature ultrasound probe. As many of the areas we’re examining lie next to areas where the scope is able to be passed, excellent ultrasound images of these organs can be obtained. It also allows for the passage of a biopsy needle (FNA) into the area of concern so that a specimen can be taken to examine under the microscope.
