Primary cholangiography (or perioperative): Done in the operation room during a biliary drainage intervention. Secondary cholangiography: Done after a biliary drainage intervention. In both cases fluorescent fluids are used to create contrasts that make the diagnosis possible.
Percutaneous transhepatic cholangiography, percutaneous hepatic cholangiogram (PTHC) is a radiological technique used to visualize the anatomy of the biliary tract. [1] A contrast medium is injected into a bile duct in the liver , after which X-rays are taken.
Besides providing information regarding the biliary system, MRCP also provides information regarding surrounding solid organs and blood vessels, thus useful for planning the resection of pancreatic cancer and look for complications of primary sclerosing cholangitis such as liver cirrhosis and cholangiocarcinoma.
Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems.

Primary biliary cholangitis (PBC), previously known as primary biliary cirrhosis, is an autoimmune disease of the liver. [ 1 ] [ 2 ] [ 3 ] It results from a slow, progressive destruction of the small bile ducts of the liver, causing bile and other toxins to build up in the liver, a condition called cholestasis .
Primary sclerosing cholangitis is one of the major known risk factors for cholangiocarcinoma, [40] a cancer of the biliary tree, for which the lifetime risk among patients with PSC is 10-15%. [3] This represents a 400-fold greater risk of developing cholangiocarcinoma compared to the general population. [ 1 ]
The incidence of cholangiocarcinoma increases with age, and the disease is slightly more common in men than in women (possibly due to the higher rate of primary sclerosing cholangitis, a major risk factor, in men). [47] The prevalence of cholangiocarcinoma in people with primary sclerosing cholangitis may be as high as 30%, based on autopsy ...
