Following percutaneous removal of retained biliary calculi through a t-tube tract, a tube should be reinserted over a guide wire. Reinsertion usually is easy; however, if buckling occurs, a coaxial system consisting of a t-tube over a teflon dilator will give added stiffness, and the t-tube will advance easily into the common bile duct.
经T管窦道经皮取出残留胆管结石后，应通过导丝重新插入一根管子。重新插入通常很容易；然而，如果发生弯曲，由置于聚四氟乙烯扩张器上的T管组成的同轴系统将增加硬度，并且T管将很容易推进到胆总管中。
