Efficacy of BISAP score versus Ranson’s score to determine the severity index 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 posing a significant therapeutic challenge for the health care providers. Bedside index of severity in acute pancreatitis (BISAP) is a scoring system that would precisely predict severity as early as within the first 24 hours of the course of acute pancreatitis. This study aims to compare BISAP and Ranson’s score to establish the validity of a simple and accurate clinical scoring system for stratifying patients.Methods: All 84 cases admitted at HSK Hospital and SNMC, Bagalkot and diagnosed as acute pancreatitis were included in this study, from January 2019 to June 2020. Clinical evaluation in the form of detailed history, per abdominal, systemic examination and laboratory investigations, both BISAP and Ranson’s score were applied and compared, based upon data obtained at admission, within 24 hours and at 48 hours of hospitalization.Results: Out of 84 cases with a male to female ratio of 16:1, majority belonged to age group 31-40 years (42%) and most common etiological factor being alcohol consumption (74%); 19% patients had severe acute pancreatitis and 68% patients had length of hospital stay less than a week. Major organ failure and pancreatic necrosis, severity of BISAP and Ranson’s score were found to be significantly correlated, (p<0.001); mortality was found to be 1.2%.Conclusions: Compared to Ranson’s score, BISAP score is equally effective in finding out the frequency of severity and predicting mortality in patients with acute pancreatitis .The values in BISAP score are instantaneous with no time delay.
