A total of 40 cases referred for postoperative reexploration of the biliary tract via the T-tube trace was reviewed. In selected cases, a modified technique of dilatation of the T-tube tract or bile ducts and endoscopy via the T-tube tract was used. Dilatation of the T-tube tract is a relatively simple procedure that was necessary in over one-half of our cases, since the retained stone was larger than the T-tube inserted during surgery. A new T-tube with a larger external limb was developed in order to reduce the necessity for dilatation of the biliary-cutaneous fistulous tract. Fiberoptic endoscopy of the biliary system via the T-tube tract offers another means for removing large or impacted stones and for investigating mucosal defects. This modified technique has reduced the number of patients requiring surgical reexploration.
回顾了总共40例经T管窦道进行术后胆道再探查的病例。在部分病例中，采用了改良的T管窦道或胆管扩张技术以及经T管窦道的内镜检查。T管窦道扩张是一种相对简单的操作，在我们超过一半的病例中是必要的，因为残留结石大于手术中插入的T管。为了减少胆皮瘘管扩张的必要性，开发了一种具有更大外肢的新型T管。经T管窦道对胆道系统进行纤维内镜检查为取出大的或嵌顿的结石以及检查黏膜缺损提供了另一种方法。这种改良技术减少了需要进行手术再探查的患者数量。
