ABSTRACT
BACKGROUND:
The endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography were methods used for diagnosis of the diseases in the biliary and pancreatic ducts.AIM:
Compare the diagnostic concordance among, analyzing sensitivity, specificity, positive predictive value, negative predictive value and accuracy. PATIENTS/METHODS:
There were 41 patients in the studied group, divided in two groups I--without biliary or pancreatic tract obstruction, and II--with obstruction. Group II was further divided in A--obstruction due to lithiasis, and B--due to other causes.RESULTS:
Concordance between the two methods was found in 67% in group I and 82% in group II. Sensitivity of endoscopic retrograde cholangiopancreatography was 94% and magnetic resonance cholangiopancreatography was 89%. Specificity of endoscopic retrograde cholangiopancreatography was 100% and magnetic resonance cholangiopancreatography was 67%. Magnetic resonance cholangiopancreatography positive predictive value was 93%, the negative predictive value was 50% and the accuracy was 85%.CONCLUSION:
Both methods showed the same sensitivity
