Abstract:

Malignant biliary obstruction is caused by biliary or other metastatic malignant tumors, mainly with obstruction jaundice, bile duct dilatation, and liver damage as its clinical presentation. In later period, patients are characterized with deterioration of liver function, easily combined with acute obstructive and suppurative cholangitis and kidney function exhaustion. Most of the patients are late for medical treatment and lose the chance of operation. The endoscopic retrograde cholangiopancreatography(ERCP), a palliative minimally invasive treatment, has endoscopic nasobiliary drainage and stents, intraductal radiofrequency, endoscopic photodynamic therapy, and been carried out widely. Compared with percutaneous transhepatic catheter drainage (PTCD), ERCP has advantages of less pain and simpler operation. In this paper, the main methods and research progress of ERCP in relieving malignant biliary obstruction are reviewed.

Key words: Cholestasis, Cholangiopancreatography, endoscopic retrograde, Biliary obstruction, Stent
