In the management of biliary tract disorders, direct cholangiography should be chosen over ultrasonic examination if the bile ducts are thought to be obstructed. Contrast medium can be introduced into the bile ducts either percutaneously or retrogradely via the ampulla of Vater, the choice of technique often depending on the clinical situation. Direct access to the biliary tree for diagnostic purposes has also led to advances in the treatment of mechanical disorders of the ducts.
在胆道疾病的管理中,如果认为胆管存在梗阻,应选择直接胆管造影而非超声检查。造影剂可经皮或经十二指肠乳头逆行注入胆管,技术的选择通常取决于临床情况。为诊断目的直接进入胆道系统也推动了胆管机械性疾病治疗的进展。
