OBJECTIVE: Compare hemoconcetration, APACHE II and Ranson scores as early predictors of severity defined by Atlanta criteria in patients with acute pancreatitis at Hospital Nacional Cayetano Heredia. MATERIALS AND METHODS: Retrospective descriptive study between December 2009 to November 2010 done using a data collection sheet to gather study relevant information. We classified acute pancreatitis into mild or severe according to Atlanta symposium criteria for organ failure and/or local complications. Comparison of hematocrit values was made using a t Student test to detect a significant difference and the area below the ROC curve was analyzed. RESULTS: Counting with 151 patients, 103 women (68.2%), with mean age of 45.5 ± 19.17 years, 112 mild pancreatitis (74.2%) and 39 severe (25.8%). Mean hematocrit in mild cases was 38.40 ± 4.77% and 39.78 ± 7.35% in severe group with p equal to 0.182. Area below the ROC curve of 0.89 y 0.68 for APACHE II and Ranson scores respectively. CONCLUSION: Hemoconcentration and Ranson proved not to be as useful as APACHE II score in predicting severity in acute pancreatitis.
