Biliary obstruction is usually seen in biliary calculi, malignant tumor of biliary tract, etc., and the patient may show symptoms of abdominal pain, jaundice, shivering, fever, etc. Malignant obstructive jaundice is stenosis or obstruction of different parts of the intrahepatic and extrahepatic bile ducts caused by various malignant tumors, and decompression of the bile ducts is the key of clinical treatment of the malignant obstructive jaundice. Biliary drainage is the main pressure-reducing method for treating malignant obstructive jaundice. The biliary tract drainage method comprises internal drainage and external drainage. The internal drainage is to place a stent on a bile duct, drain the bile from the bile duct to a duodenal papilla along the excretion path of the bile, and discharge the bile into the duodenum, so that the bile is normally discharged into the intestinal tract. The external drainage is to puncture the bile directly from gall bladder or bile duct by puncturing the liver through skin, and the secreted bile is drained out of the body directly. The biliary tract drainage has the main functions of ensuring the smoothness of biliary tract drainage, reducing jaundice, facilitating the control of biliary tract infection and relieving the symptoms of patients. How to choose the biliary drainage method is also determined according to the specific condition of the patient.
