Research updates on surgical treatments for portal hvpertension / 中华肝胆外科杂志

ABSTRACT

Portal hypertension is a common clinical syndrome in chronic liver disease,such as schistosomiasis,portal vein occlusion cirrhosis and so on,which can be diagnosed when the hepatic venous pressure gradient is (HVPG) ＞ 5 mmHg (1 mmHg =0.133 kPa).It could lead to gastroesophageal varicose veins rupture,ascites,spontaneous bacterial peritonitis,hepatorenal syndrome,hepatopulmonary syndrome,hepatic encephalopathy and some other serious complications,and is the primary death cause in cirrhosis and liver transplantation.The development of portal hypertension has experienced 4 phases ineluding the research about portal hypertension related theories and animal trial phase,preclinical tests and data accumulation phase,devascularization and shunts rapid development phase,the development phase of new technologies such as interventional and endoscopic surgical treatment,liver transplantation since the middle of the 19th century.The surgical procedures have been modified,which greatly reduce the complication and improve the life quality after operation.But so far none of them can cure portal hypertension thoroughly.This paper not only introduces the pathophysiologic basis of the surgical treatment,but also reviews the history of its development to summarize the recent progress,which may facilitate its surgical treatment.
