[Percutaneous treatment of benign biliary stenosis: bilioplasty and stenting].
We reviewed our personal experience in 46 patients with biliary strictures, who underwent percutaneous balloon dilatation between 1983 and 1988. The strictures were iatrogenic in 24% of the cases, anastomotic in 52%, inflammatory in 17%, and associated with sclerosing cholangitis in 7%. The treatment consisted in dilating the bile ducts with balloon catheters of different kinds and sizes ("bilioplasty") and placing an internal drainage catheter for a varying period of time ("stenting"). In 22 patients the catheter was removed after an average time of 7.7 months. The rate of stricture recurrence was 13.5% (average follow-up: 20 months). In the remaining 24 patients the stents are still in situ, waiting for removing. Major complication rate was 6.4% (2 pleural effusions and 1 hepatic artery bleeding). We also report our initial experience with metallic self-expanding stents which appear as a promising tool in the management of recurring strictures.
