The needle orientation recommended for transhepatic cholangiography has a consensus in the literature for the sagittal and the transverse planes. Because of differing recommendations for the needle orientation in the coronal plane, the location of the porta hepatis was analyzed in 50 patients undergoing computed tomography. The mean ratio between skin to the porta hepatis distance and AP patient diameter is 0.38. The best puncture site therefore lies anteriorly to the halfway mark at the midaxillary line by about 3 cm.
经肝胆管造影术推荐的穿刺针方向在矢状面和横断面上在文献中有共识。由于冠状面穿刺针方向的推荐不同，对50例接受计算机断层扫描的患者的肝门位置进行了分析。皮肤至肝门距离与患者前后径的平均比值为0.38。因此，最佳穿刺点位于腋中线中点前方约3 cm处。
