Abstract

Objective: To establish the diagnostic accuracy of BISAP in detecting the severe acute pancreatitis keeping computed tomography severity index as gold standard. Study Design: Cross-sectional study Place and Duration of Study: Department of Gastroenterology, Hayatabad Medical Complex, Peshawar from April 16th 2018 to 16th October 2018. Methodology: One hundred and twenty nine patients of age range of 18-60, of either gender having severe acute pancreatitis were included. While patients already diagnosed as severe acute pancreatitis and having known history of chronic pancreatitis were excluded. Patients were subjected to CT scan to confirm whether the severe acute pancreatitis is present or not. All CT scans were reported by single experiences radiologist. Results: There were 30.3% were males and 69.7% were females with mean age 42±11.03 years. BISAP had sensitivity 92.74%, specificity 80%, positive predictive value 99.13%, negative predictive value 20.76% and the overall diagnostic accuracy was 92.24%. Conclusion: BISAP had sensitivity 93.61%, specificity 100%, positive predictive value 100%, negative predictive value 40% and the overall diagnostic accuracy was 93.87% in severe acute pancreatitis keeping CT severity index as gold standard. Keywords: Accuracy, Severe acute pancreatitis, Computed tomography
