Core Tip

Core tip: After rectal thallium instillation, radioactive isotope activity in the heart and liver was measured (the shunt index). It was higher in the varices group, the hepatic encephalopathy group, and the variceal bleeding group than in the control group (P < 0.001). Multivariate analysis showed that the index was an independent risk factor for predicting decompensated liver cirrhosis. When the shunt index was greater than 0.75, there was a significant increase in the number of decompensated events. The thallium shunt index is a good predictor of cirrhosis-related complications.
