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, multiorgan failure. Since the morbidity and mortality of Acute Pancreatitis differ markedly between mild and severe disease (mild < 5% vs severe 20–25%), it is very important to assess severity as early as possible. Various scoring systems like APACHE II scoring, RANSON scoring and BISAP have been used to asses Severity in Acute Pancreatitis. Aim and objective: To assess the accuracy of BISAP scoring system vs RANSON scoring system in predicting Severity in an attack of acute pancreatitis. Materials and methods: In this study, 60 in-patients presenting with features of acute pancreatitis Government Stanley Medical College General Hospital from November 2016 to September 2017 had been studied. It was a perspective and a retro prospective study. BISAP score and Ranson’s score was calculated in all such patients based on data obtained within 48 hours of hospitalization. Results: According to Atlanta Revised criteria, 30 patients had mild pancreatitis, 20 patients had moderately severe pancreatitis, 10 patients had severe pancreatitis. Of the 60 patients, 37 patients had Ranson's score less than or equal to 3. 23 patients had a score of more than 3.Of the 60 patients, 39 patients had a BISAP score less than or equal to 3, 21 patients had a score more than 3. Conclusion: 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. Moreover, the values in BISAP score are instantaneous and there is no time delay. Ranson’s score takes a minimum of 24 hours.
