We analyze the information of 57 patients being a mortality of 19,3%, APACHE II in relation to mortality showed an area under the curve of 0,847 with a I.C. 95% (0,7415 - 0,9541) superior to the Ranson to the 48 hours with an area under the curve of a 0,687 and IC 95% of (0,5518 to 0,8085); was not an association with the score of Ranson to the entrance nor with the classification of Balthazar, curves ROC for APACHE II and Ranson to the 48 hours did not show to differences in their areas, being a greater tendency in the validity of the scale of APACHE II. In the present study the markers that showed a greater validity in the prediction of mortality were the score of APACHE II and the score of Ranson to the 48 hours, being Apache II the one that both showed one better tendency the discrimination without significant differences between scores
