207 MELD VS CPS FOR PROGNOSIS IN CIRRHOSIS. RESULTS FROM A MULTICENTRE STUDY

Results: Variation coefficients for the balloon catheter were 0.07, 0.02, and 0.06 for HVPG, WHVP, and FHVP, respectively. Variation coefficients for the straight catheter were 0.17 (HVPG), 0.06 (WHVP), and 0.07 (FHVP), and significantly higher for HVPG and WHVP (p < 0.001) compared with the balloon catheter. When comparing the WHVP measurements with the portal venous pressure, the calculated intraclass correlation coefficient was 0.72 (p =0.004) using the balloon and 0.58 (p =0.011) using the straight catheter. Conclusion: Reproducibility and reliability of the HVPG measurement was higher using the balloon catheter, which should be the preferred procedure to measure HVPG. The significant greater variation coefficient of the straight catheter may become clinically relevant, if this method is used to perform repeated measurements during the management of cirrhotic patients.
