This is a procedure in which a catheter (see CATHETERS) is passed via an ENDOSCOPE into the AMPULLA OF VATER of the common BILE DUCT. The duct is then injected with a radio-opaque material to show up the ducts radiologically. The technique is used to diagnose pancreatic disease as well as obstructive jaundice.... endoscopic retrograde cholangiopancreatography (ercp)
A technique for displaying the bile ducts (see BILE DUCT) and pancreatic ducts (see PANCREAS) with radio-opaque dyes. These are introduced via a catheter (see CATHETERS) inserted into the ducts through an incision in the skin. An X-ray is then taken of the area.... percutaneous transhepatic cholangiopancreatography (ptc)
imaging of the bile duct and pancreatic duct. A catheter is carefully manipulated into the ducts via direct puncture through the abdomen under radiological guidance. Contrast material is flushed through the catheter to delineate the ducts (see also cholangiography). This procedure is often performed in cases of obstructive jaundice prior to insertion of a biliary drain or stent when *ERCP is not possible.... percutaneous transhepatic cholangiopancreatography
