[Percutaneous extraction of gallstones by T-drainage (author's transl)]

Experience gained from the percutaneous extraction of biliary stones from 12 patients is reported. On three occasions the concrements could not be completely removed. A Zeiss sling proved more successful than a Dormia basket; with this it is not always necessary to use the guidable catheter. Conditions necessary for success are adequate thickness of the T-tube, and adequate time for the drainage (about three weeks) to permit the development of a track suitable for catheterisation. The method is so simple that it is recommended before an attempt is made to perform endoscopic extraction and papillotomy.
