A retrospective study has been conducted in 36 cholestatic patients to determine the diagnostic accuracy of ultrasonography in preliminary differentiation of obstructive from non-obstructive hepato-biliary disease. Due to the high rate of correct biliary duct caliber evaluation, ultrasonography has proved itself an excellent screening method in patients with cholestasis of uncertain origin. The choice of the subsequent more invasive diagnostic examinations (ERC, PTC, laparoscopy) depends on the ultrasonic findings.
对36例胆汁淤积患者进行了一项回顾性研究，以确定超声检查在初步区分梗阻性和非梗阻性肝胆疾病方面的诊断准确性。由于胆管管径评估的正确率较高，超声检查已证明自身是一种用于病因不明的胆汁淤积患者的出色筛查方法。后续更具侵入性的诊断检查（内镜逆行胰胆管造影、经皮肝穿刺胆管造影、腹腔镜检查）的选择取决于超声检查结果。
