Diagnostic Accuracy of Ultrasound in Correlation to Alkaline Phosphatase Levels in Patients with Biliary Obstructions

Abstract: Abdominal Ultrasonography (USG) is an appropriate initial screening method for detection of biliary tract disease the consultants sometimes encounter patients who only have ndings of dilatation of the Common Bile Duct (CBD) on US without specic biliary symptoms or jaundice. Objective: To determine the diagnostic accuracy of ultr a sound in corr e l a tion to a lka line phosphatase levels in patients with billiary obstructions. Methods: Total 100 patients were selected during 6 months. Data were tabulated and analyzed by SPSS version 24.0. The quantitative variables were presented in form of mean±S.D and Chi square test was used to test the association between categorical variables. A semi-structured questionnaire was prepared and nalized after pre-testing. Results: 59 (0.59%) females and 41 (0.41%) males. 63 (0.63%) patients presented with abdominal pain. 85(0.85%) have CBD, 64 (0.64%) has stones as common cause of obstruction. The mean scoring of Alkaline Phosphate Level (APL) was 439.9 9+10.54. There was signicant association between the age groups and cause of obstruction in patients, gender and complaints of patients (pvalue < 0.05). Conclusions: A signicant number of causative biliary tract lesions in asymptomatic adults with dilatation of the CBD on routine abdominal US; no laboratory or demographic parameters were useful for discrimination.Key words: Ultrasonography, Alkaline Phosphate Level, Common bile duct, Biliary obstruction
