Abstract
Introduction: Acute pancreatitis is an acute inflammation of the pancreas which poses a major challenge to treating surgeon in its management. Various scoring systems has been developed for predicting severity of acute pancreatitis however none of them are accurate. The aim of this study was to assess the accuracy of BISAP scoring system vs Ranson’s scoring system in prediciting severity in an attack of acute pancreatitis and to compare predictability of organ failure, necrosis and mortality between BISAP scoring and Ranson’s scoring system.
Methods: This is a prospective comparative study conducted for a period of 22 months. . BISAP score and Ranson’s score were calculated in all diagnosed cases of acute pancreatitis. Data were obtained within 24 hours and 48 hours of hospitalization. Sensitivity, Sensitivity, PPV, NPV of both scoring system was calculated and compared.
Results: A total of 81 patients with diagnosis of acute pancreatitis were included during the study period. 45(55.6%) were male and 36(44.4%) were female. Median age is 46 yr. Most common etiology was biliary 67(82.7%) followed by alcohol 10 (12.35%).15 (18.52%) patients were categorized as severe pancreatitis according to Atlanta classification. 19 (23.5%) patients had a Ranson’s score of >3 and 21 (25.9%) patients had a BISAP score of ≥3. Both Ranson’s and BISAP scoring system was statistically significant in determining SAP (p-value <0.001). Sensitivity, specificity, positive predictive value and negative predictive value of Ranson’s and BISAP score was calculated to be 73.3%, 87.9%, 57.9%, 93.5% and 80%, 86.4%, 57.1%, 95% respectively.
Conclusion: Both Ranson’s and BISAP scoring system is similar in predicting SAP. However, BISAP has the advantage due to its simplicity.
