阻塞性黄疸是由肝内阻塞和肝外阻塞引起。肝内阻塞常是由于病毒性肝炎、妊娠复发性黄疸、药物性肝损害、原发性胆汁性肝硬化等原因,使肝细胞内胆汁排泌器官功能失调,胆流障碍所致的综合征,临床上称为肝内胆汁淤积综合征,仍属内科性黄疸的范畴。肝外阻塞常是由于胆石症、胆道蛔虫症、胆管炎、乏特氏壶腹周围癌、胰腺癌、胆道术后胆管狭窄等原因,引起胆道系统机械性阻塞,临床上称其为“外科性黄疸”。这类黄疸的临床表现常相似,但治疗原则完全不同,因此二者必须加以鉴别,及时的确诊和治疗,对预后关系很大。
Obstructive jaundice is caused by intrahepatic obstruction and extrahepatic obstruction. Intrahepatic obstruction is often due to viral hepatitis, pregnancy-induced recurrent jaundice, drug-induced liver damage, primary biliary cirrhosis and other reasons, so that intrahepatic bile excretion organs dysfunction, biliary flow syndrome, Clinically known as intrahepatic cholestasis syndrome, jaundice is still the scope of the medical. Extrahepatic obstruction is often due to cholelithiasis, biliary ascariasis, cholangitis, Vate ampullary cancer, pancreatic cancer, biliary tract after biliary stricture and other causes of biliary system mechanical obstruction, clinically called “surgical jaundice”. The clinical manifestations of such jaundice are often similar, but the treatment principle is completely different, so the two must be identified, timely diagnosis and treatment, a great relationship between the prognosis.
