Performance of the Choledocholithiasis Diagnostic Score in Patients with Acute Cholecystitis

Abstract

Suspicion of choledocholithiasis in patients with acute cholecystitis was a rare event (<1%). The sensitivity of the high risk score was approximately the same as found in published series with patients with suspected choledocholithiasis overall (86%), while the positive predictive value was substantially lower (52 vs. 79.8%). Therefore, in patients with acute cholecystitis and suspected choledocholithiasis, this score should not be used to screen for common bile duct stones, and a sensitive method should be used prior to ERCP.
