Thirty patients were studied by diagnostic ultrasound and percutaneous transhepatic or surgical cholangiography to evaluate diagnostic accuracy in differentiating obstructive from nonobstructive hepatobiliary disease. Correct recognition of biliary duct caliber was accomplished by ultrasound in 86% of cases, and was most accurate (89%) in patients with dilated intrahepatic biliary radicals. Diagnostic ultrasound is sufficiently accurate to be a useful screening tool for determining the caliber of the biliary duct system and, on this basis, obstructive from nonobstructive hepatobiliary disease.
对30例患者进行了诊断性超声检查以及经皮肝穿刺胆管造影或手术胆管造影，以评估鉴别梗阻性与非梗阻性肝胆疾病的诊断准确性。超声在86%的病例中正确识别了胆管管径，在肝内胆管扩张的患者中最为准确（89%）。诊断性超声足够准确，可作为确定胆管系统管径的有用筛查工具，并在此基础上鉴别梗阻性与非梗阻性肝胆疾病。
