A Study on Diagnostic Accuracy of Biochemical Markers and Trans–abdominal Ultrasonography in Comparison to Multi-Detector Computed Tomography in Detection of Acute Pancreatitis

Abstract

Acute pancreatitis is an acute, mainly diffuse, inflammatory process of the pancreas. Computed Tomography (CT) scan is the modality of choice for diagnosis of acute pancreatitis. But non-availability of Computed Tomography (CT) scan in all health facilities made detection of acute pancreatitis is problemsome. MATERIALS AND METHODS100 clinically suspected for acute pancreatitis patients were tested for abnormal biochemical markers, followed by examined by USG and then by MDCT in Radiodiagnosis Department of AGMC and GBP Hospital and findings were compared. Sensitivity, specificity, positive predictive value and negative predictive value were calculated. RESULTSThe sensitivity and specificity of trans-abdominal ultrasonography was calculated as 75% (CI 64.06% -84.01%) and 100% (CI 83.16%-100%). CONCLUSIONUSG had similar sensitivity, but higher specificity value than serum markers (Amylase and Lipase).
