perioperative care of hvpg measurement (chess1904): an international multicenter survey

Conditions: Portal Hypertension; Cirrhosis, Liver

Summary: hepatic venous pressure gradient (hvpg) is an invasive test and requires technical skills of the operator and specialized instruments. hvpg measurement and anesthesia can cause stress responses in the body, which in turn lead to inflammatory response and immune function suppression. thus, the perioperative care for patients undergoing hvpg measurement is crucial. this research trial studies comprehensive patient and medical worker questionnaires in predicting complications in patients with cirrhosis undergoing hvpg measurement. comprehensive patient and medical worker questionnaires may help identify complications, such as the need for assistance in taking medication, decreased mobility and released tension that may improve outcomes.

portal hypertension is an important factor affecting the clinical outcomes of cirrhosis patients, and its severity determines the occurrence of development of cirrhosis complications, such as rupture and bleeding of gastroesophageal varices, ascites, and hepatorenal syndrome. the direct measurement of portal pressure is an extremely invasive and high-risk procedure. in addition, changes in intra-abdominal pressure will affect the portal pressure, which leads to unreliable results. the hepatic venous pressure gradient (hvpg) is the difference between wedged hepatic venous pressure and free hepatic venous pressure and reflects the pressure difference between the hepatic portal vein and the intra-abdominal veins. in recent years, the status of hvpg in clinical application of cirrhotic portal hypertension has gradually improved. in 2016, the american association for the study of liver diseases (aasld) issued a consensus on risk stratification, diagnosis, and management of portal hypertensive bleeding in cirrhosis and re-emphasized the value of hvpg in assessing the cirrhosis staging, occurrence of complications and treatment goals. however, hvpg is an invasive test and requires technical skills of the operator and specialized instruments. hvpg measurement and anesthesia can cause stress responses in the body, which in turn lead to inflammatory response and immune function suppression. thus, the perioperative care for patients undergoing hvpg measurement is crucial. this research trial studies comprehensive patient and medical worker questionnaires in predicting complications in patients with cirrhosis undergoing hvpg measurement. comprehensive patient and medical worker questionnaires may help identify complications, such as the need for assistance in taking medication, decreased mobility and released tension that may improve outcomes.
