A Comparative Study between Bedside Index of Severity in Acute Pancreatitis (BISAP) and Ranson’s Score in Predicting Severity of Acute Pancreatitis in Correlation with Computerized Tomography Scan in Kumaun Region

Introduction – Because of the variability and seeming unpredictability of acute pancreatitis, clinical scoring systems have been developed to predict the severity of acute pancreatitis and, as important, for patient stratification and enrolment in clinical trials. Ranson’s criteria is the most commonly used scoring system and is based on 11 clinical and laboratory parameters measured within the first 48 hours of admission to the hospital. A new scoring system, the BISAP (Bedside Index for the Severity in Acute Pancreatitis) helps to identify the patient at risk of mortality prior to the development of multi-organ failure. BISAP scoring system is relatively simple and quick way to assess the severity of acute pancreatitis on admission and helps improving the management of the patient. Methods - All confirmed cases of acute pancreatitis in 2 years of study period based on clinical, hematological, radiological findingswere included in this study. All data concerning etiology, length of hospital stay, treatment, complications and deaths were recorded and analyzed in all patients forming study group. BISAP score and Ranson's score were calculated in all such patients. Special emphasis was made to collect data regarding organ failure, pancreatic necrosis and mortality and scoring systems was compared with them. Results – Both Ranson and BISAP were almost equal in predicting the severity of acute pancreatitis. Both were efficacious in assessing the predictability of organ failure but latter was much easier and can be preferred over former. Conclusion - From this study, we can conclude that 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
