The diagnosis of proctated jaundice is done in 50% of all cases by clinical examination; in 30% of all cases by peritoneoscopy; in the other 20% instrumental opacification of the biliary tract is required (before the laparotomy) in order to determine the site and the nature of the cholestasis. Among these instrumental devices, a transhepatic cholangiography with the Okuda needle allows biliary tract opacification in 98% of all cases if the obstacle is extra-hepatic and in 69% of all cases if the obstacle is intra-hepatic. This technique is easy to perform, without danger, and readily available to any physician. It should be performed after the peritoneoscopy and before the retrograde cholangiography.
50%的前列腺黄疸病例通过临床检查确诊；30%的病例通过腹腔镜检查确诊；另外20%的病例（在剖腹手术前）需要进行胆道造影以确定胆汁淤积的部位和性质。在这些检查手段中，如果梗阻位于肝外，使用奥田针进行的经肝胆管造影在98%的病例中能使胆道显影；如果梗阻位于肝内，则在69%的病例中能使胆道显影。该技术操作简便、无危险，任何医生都可轻易掌握。应在腹腔镜检查后、逆行胆管造影前进行。
