Comparison of endoscopic retrograde and intravenous cholangiography in diagnosis of biliary calculi.
The results of endoscopic retrograde cholangiography (E.R.C.) and intravenous cholangiography (I.V.C.) were compared in patients undergoing surgery for biliary calculi. E.R.C. gave a significantly higher rate of correct diagnosis of gallbladder calculi (p = 0.026) and common bileduct calculi (p = 0.002) than I.V.C. Biliary stones may thus frequently be present in patients with a normal I.V.C. and E.R.C. may reduce the rate of diagnostic errors in patients with symptoms of biliary disease.
