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.
对接受胆结石手术的患者，比较了内镜逆行胆管造影术（E.R.C.）和静脉胆管造影术（I.V.C.）的结果。与I.V.C.相比，E.R.C.对胆囊结石（p = 0.026）和胆总管结石（p = 0.002）的正确诊断率显著更高。因此，I.V.C.正常的患者可能经常存在胆石症，而E.R.C.可能降低胆道疾病症状患者的诊断错误率。
