Clinical significance of ultrasonography, computed tomography, and biochemical tests in the rapid diagnosis of gallstone-related pancreatitis: a prospective study.

摘要: Summary Real-time ultrasonography (US), computed tomography (CT), and biochemical tests were prospectively performed to detect gallstones in 88 consecutive patients immediately after the onset of an attack acute pancreatitis. The sensitivity was 84.6% when had three or more positives five parameters [including serum bilirubin, alkaline phosphatase (AP), gamma-glutamyl transpeptidase (GGT), alanine transaminase (ALT), transaminase-aspartate (ALT-AST) ratio]. sensitivity, specificity, accuracy 71.8, 98.0, 86.4% for US, 52.9%, 100%, 79.5% CT. improved 82.1, 100, 93.2% by combination US CT, 94.9, 97.7% tests. Adding CT resulted only a slight improvement accuracy. In conclusion, can provide best noninvasive method rapidly detecting as etiological factor Computed is not cost-effective. A positive result despite negative finding calls intensive search further investigation with endoscopic retrograde cholangiography repeated examinations.
