title: Bilary tract exploration via T-tube tract: improved technique.
abstract: 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.
