The present authors have made it a rule to use a modified Mellet-Guy's method for measuring pressure in the bile duct. The determined manometric pressure expressed in curve has been classified into (a) basal pressure, (b) rising time, (c) perfusion pressure, (d) dumping time and (e) residual pressure. The basal pressure (a) represents a static pressure free from any load in the bile duct. The rising time (b) varies with factors including the measuring apparatus, ductal elasticity and capacity, resistance at the choledochal terminal, and the volume of physiological saline infused. The perfusion pressure (c) is likely to undergo interference of a variety of factors such as the ductal diameter, mural elasticity and thickness, resistance at the choledochal terminal, along with the measuring apparatus. The dumping time (d), free from the influence of the measuring apparatus, is considered to be an important guide for us to guess the condition of choledochal terminal. The residual pressure (e) and the trend of manometric pressure curve help us to surmise the choledochal terminal resistance and the presence of ductal abnormalities. After all, among the above factors, the dumping time and the residual pressure are apparently available for objective evaluation of bile duct pressure.
本文作者已将使用改良的梅莱特 - 居伊方法测量胆管压力作为一项规则。以曲线表示的测定压力计压力已分为：（a）基础压力、（b）上升时间、（c）灌注压力、（d）排空时间和（e）残余压力。基础压力（a）代表胆管中无任何负荷时的静压。上升时间（b）随多种因素而变化，包括测量仪器、胆管弹性和容量、胆总管末端阻力以及注入的生理盐水体积。灌注压力（c）可能会受到多种因素的干扰，如胆管直径、管壁弹性和厚度、胆总管末端阻力以及测量仪器。排空时间（d）不受测量仪器的影响，被认为是我们推测胆总管末端状况的重要指标。残余压力（e）和压力计压力曲线趋势有助于我们推测胆总管末端阻力和胆管异常情况。毕竟，在上述因素中，排空时间和残余压力显然可用于客观评估胆管压力。
