Extrahepatic Biliary Obstruction: Sensitivity and Specificity

Introduction: Extrahepatic biliary obstruction reflects inability of bile to leave the liver and/or gallbladder with the obstruction occurring outside the liver. One common cause is Cholelithiasis leading to Choledocholithiasis, but tumors can also obstruct the common bile duct.

Differential Diagnoses include: Choledocholithiasis

The sensitivity and specificity of findings for Extrahepatic Biliary Obstruction are listed below. See the left navigation bar to change the display.

**Note that calculating probabilities from more than one finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)
