【摘要】 １９９２年１月至１９９３年１月我院用超声碎石术治疗１４例肝内外胆管巨大嵌顿结石取得满意效果。其特点：１．只对结石起作用而不对软组织如胆管壁产生作用，避免了胆管壁损伤出血、穿孔等并发症。２．不需取石网套住结石再碎石，嵌顿巨大结石易直接粉碎，碎石率１００％。３．操作简单，需时短，病人痛苦小。４．＂硬镜＂＂软镜＂相结合可互补不足。５．经皮胆镜短小灵活，外径较细，可直接进入扩张的Ⅰ、Ⅱ级肝管，对处理肝内胆管嵌顿结石独具特色。更多还原

【Abstract】 Since Jan. 1992 to Jan. 1993, we had achieved a satisfactory effect by using ultrasonic lithotripsy on 14 cases of large or impacted intrahepatic & extrahepatic bile duct lithiasis during or after operation. Our experiences shew the advantages of this technique : (a)The ultrasonic lithotripte only act on lithiasis but not on soft tissues like the bile duct wall. So the possibility of the injury and perforation to the bile duct were avoidable. (b)It’s much easier and more accurate to work on large and impacted stones in stead of using the stone basket, with a 100% of lithotriptic rate.(c)It can mutually remedy the disadvantages of using hard or soft scope. (d)It’s simple and easy method which needs a short time. The patients feel less pains. (e)Being small in outer diameter and easyhandling, the percutaneous choledochoscope can directly enter the dilated hepatic duct 1 & 2. It’s proved to be a specific way of treating intrahepatic bile duct lithiasis, especially for impacted stones.更多还原
