Goals: To determine whether increased pulmonary artery pressure (PAP) following transjugular intrahepatic portosystemic shunting (TIPSS) results in short-term mortality or cardiorespiratory complications.
Background: TIPSS is frequently performed for complications of cirrhosis. PAP increases following TIPSS; however consequences of this phenomenon are unknown.
Background: Nonalcoholic steatohepatitis (NASH) is a form of fatty liver disease that is increasingly recognized. There are limited data on the prevalence of NASH and the role of risk factors for NASH among the morbidly obese.
Hypothesis: The prevalence of asymptomatic NASH among morbidly obese patients undergoing gastric bypass surgery is high, and there are identifiable risk factors for NASH.
