Papillary function in cholecystolithiasis patients was examined by intraoperative biliary manometry using a new balloon catheter. Pressure measurement was performed in each patient with the balloon deflated and inflated. When the balloon was inflated, the influence of the volume and compliance of the biliary tree was minimized to yield a precise evaluation of papillary function. From our analysis, resting pressure, residual pressure, onset time, and recovery time proved to be influenced by the volume and compliance of the biliary tree. Therefore, these four parameters could not reflect the papillary function exactly. On the other hand, perfusion pressure was not affected by the volume and compliance of the biliary tree. Perfusion pressure was thought to be generated by the resistance of the choledochal outlet and reflect the papillary function. In this study, our balloon catheter proved to be very useful in minimizing the influence of the volume and compliance of the biliary tree. And it is concluded that perfusion pressure is the best parameter to evaluate the resistance of the sphincter of Oddi or papillary function.
采用新型球囊导管，通过术中胆道测压法对胆囊结石患者的乳头功能进行了检查。在球囊放气和充气的情况下，对每位患者进行压力测量。当球囊充气时，可将胆道系统容量和顺应性的影响降至最低，从而对乳头功能进行精确评估。通过我们的分析发现，静息压力、残余压力、起始时间和恢复时间均受胆道系统容量和顺应性的影响。因此，这四个参数无法准确反映乳头功能。另一方面，灌注压力不受胆道系统容量和顺应性的影响。灌注压力被认为是由胆总管出口阻力产生的，并能反映乳头功能。在本研究中，我们的球囊导管被证明在将胆道系统容量和顺应性的影响降至最低方面非常有用。得出的结论是，灌注压力是评估Oddi括约肌阻力或乳头功能的最佳参数。
