Abstract
New definitions and criteria were released at the Baveno V consensus meeting. The purposes of this study were to verify Baveno V definitions and criteria for failure to control bleeding and to determine the usefulness of the combined use of the Adjusted Blood Requirement Index [ABRI: (number of blood units)/(final hematocrit-initial hematocrit)+0.01] with Baveno V criteria. In all, 246 consecutive liver cirrhosis patients with acute bleeding associated with portal hypertension were enrolled prospectively between January 2010 and October 2012. The treatment outcome on day 5 was assessed by endoscopy. For the ABRI calculation, two hematocrit levels were used as the initial hematocrit: the first level measured upon patient arrival (ABRI-A) and the lowest level measured before transfusion (ABRI-B). Treatment failures were identified in 53 patients, of whom 24 died. Based on repeated endoscopic findings, 29 patients were identified as treatment failures, while according to Baveno V criteria, 47 patients were regarded as treatment failures. The area under the receiver operating characteristic curve (AUROC) of Baveno V criteria was 0.906, and the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio were 83.0%, 98.4%, 93.6%, 95.5%, 53.41, and 0.17, respectively. The AUROC of Baveno V criteria was significantly greater than those of Baveno IV (P = 0.0001) and Baveno II/III (P < 0.0001) criteria. Adding ABRI-A or -B to Baveno V criteria resulted in a significant reduction of the AUROC (P < 0.05).

CONCLUSION:
The Baveno V criteria are good predictors of treatment failure of early-stage acute gastrointestinal bleeding in patients with portal hypertension, while the addition of ARBI does not improve the prediction accuracy of the outcome of bleeding.
