Score BISAP validation as a prognostic system in acute pancreatitis. Validación del score de BISAP como sistema pronóstico en pancreatitis aguda

Abstract

BACKGROUND: The BISAP score is a simple system, which englobes clinical features (laboratory and imagenology tests) allowing to predict the mortality in acute pancreatitis within the first 24 hours of hospitalization. OBJECTIVE: To determine the validity of the BISAP score in the prediction of prognosis and severity of acute pancreatitis. METHOD: In order to validate the BISAP score, a study was performed in 57 patients with a diagnosis of acute pancreatitis at the moment of admission. The reference test was the Atlanta criteria which confirmed severe clinical course beyond the fifth day, in many cases supported by CT. RESULTS: 71.9% were women. The mean age was 45.33 years. Biliary lithiasis was the most frequent cause (66.7%). According to the reference test 71.9% were mild and 28.1% severe. According to the BISAP score 77.2% mild and 22.8% severe. The sensitivity and specificity for the BISAP score was of 75% and 97.56% respectively. The predictive positive value was 92.31% and the predictive negative value was 90.91%. CONCLUSIONS: The BISAP score allows to predict the severity of the acute pancreatitis.
