Comparative study between BISAP score and Ranson score in predicting severity of acute pancreatitis

Abstract

Background: Acute pancreatitis has widely variable clinical and systemic manifestations spanning the spectrum from a mild, self-limiting episode of epigastric pain to severe, life-threatening, multi-organ failure. Since the morbidity and mortality of acute pancreatitis differ markedly between mild and severe disease (mild <5% versus severe 20–25%), it is very important to assess severity as early as possible. To assess the accuracy of the BISAP scoring system versus Ranson scoring system in predicting severity in an attack of acute pancreatitis.Methods: It is a prospective and retro prospective study that was conducted, from August 2018 to November 2019. All surgical units in the headquarters hospital, Ooty. BISAP score and Ranson’s score is calculated in all such patients based on data obtained within 48 hours of hospitalization.Results: Ranson’s score of more than 3 and the BISAP score of less than or equal to 3 had the best accuracy of predicting the severity of acute pancreatitis. Both Ranson’s score and BISAP score showed higher sensitivity in the prediction of systemic complications than that of local complications.Conclusions: From this study, we can conclude that the BISAP scoring system is not inferior to Ranson’s scoring system in predicting the severity of acute pancreatitis. BISAP scoring system is very simple, cheap, easy to remember and calculate. BISAP scoring system accurately predicts the outcome in patients with acute pancreatitis.
