The use of ultrasound in the non-invasive investigation of the biliary tract and pancreas is discussed. Its accuracy in detecting gallstones in the non-acute condition is as accurate as conventional radiography, which is dependent on the excretion of contrast medium by the liver. Ultrasound is not dependent on liver function and has become the best initial investigation in persistent jaundice, acute cholecystitis, acute pancreatitis, and chronic pancreatic disease. In a retrospective study of 75 patients with acute pancreatitis liver function tests were found to be abnormal in 67% and contrast radiography proved to be of limited value. Ultrasonography performed shortly after admission showed an overall accuracy of 82% correct findings. The identification of gallstones in pancreatitis and cholecystitis permits early surgery, which reduces morbidity, improves prognosis, and is now being accepted as the treatment of choice.
本文讨论了超声在胆道和胰腺无创检查中的应用。在非急性情况下，其检测胆结石的准确性与传统放射照相术相当，传统放射照相术依赖肝脏排泄造影剂。超声不依赖肝功能，已成为持续性黄疸、急性胆囊炎、急性胰腺炎和慢性胰腺疾病的最佳初始检查方法。在一项对75例急性胰腺炎患者的回顾性研究中，发现67%的患者肝功能检查异常，造影检查价值有限。入院后不久进行的超声检查显示，总体正确诊断率为82%。在胰腺炎和胆囊炎中识别胆结石有助于早期手术，这可降低发病率、改善预后，目前已被视为首选治疗方法。
