[Percutaneous correction of benign stenosis of the bile ducts and biliary-digestive anastomosis. Percutaneous transhepatic biliplasty]

: The authors describe their experience in nine cases of transhepatic percutaneous dilatation of bile ducts benign stenosis by a Gruntzig catheter inflated at the stenotic level in order to stretch the sclerotic lesion. Despite the brief follow-up, the first results are satisfying; for this reason percutaneous dilatation of bile ducts benign stenosis could be a new procedure in the treatment of these lesions in selected cases.
