A technique used for removal of residual biliary tract stones, too large to be withdrawn through a T-tube tract, is reported. Telescoping Teflon catheters were used in one patient to dilate the tract sufficiently to remove the stone with the Dormia type wire basket.
据报道，有一种用于去除残留胆道结石的技术，这些结石太大，无法通过T形管通道取出。在一名患者中使用了可伸缩的聚四氟乙烯导管，充分扩张通道，以便用多尔米亚型金属丝篮取出结石。
