A modified technique of percutaneous transhepatic cholangiography utilizing the Chiba University needle is described. This new technique employs injection of dye through a thin flexible 22 gauge needle with a short bevel while it is slowly withdrawn under a fluoroscopic monitoring. The results of several investigators are reviewed and indicate that failure to visualize the biliary radicals with the Chiba University needle virtually rules out extrahepatic obstruction. It is anticipated that this technique will replace the traditional sheathed needle cholangiography as a diagnostic modality in the evaluation of the jaundiced patient.
本文描述了一种利用千叶大学针进行经皮肝穿刺胆管造影的改良技术。这项新技术是在荧光透视监测下缓慢拔出一根带有短斜面的22号细柔性针时，通过该针注射染料。回顾了几位研究者的结果，这些结果表明，使用千叶大学针未能使胆管显影实际上排除了肝外梗阻。预计这项技术将取代传统的带鞘针胆管造影术，成为评估黄疸患者的一种诊断方法。
