[Benign bile duct stenoses. Treatment with flexible metal wire stent or silicone prostheses (Yamakava) in nonresectable stenoses or high surgical risk cases].
BACKGROUND
High benign biliary stenoses, which can occur as a complication of disease or surgery, may be difficult to correct by open surgery and may also carry a high risk. An alternative to surgery is the percutaneous implantation of a flexible metallic stent or silicon prosthesis at the affected site.


METHODS
Twelve patients with benign biliary stenoses have been operated on in our department since March 1992, and the therapeutic success was reviewed in this study.


RESULTS
Six received a Palmaz stent and six a silicon prosthesis, with a follow-up after completion of treatment of more than 7 years and more than 3 years, respectively. Fifty percent of the patients with a stent experienced no problems and 66% of the stents remained patent (including one requiring operative intervention to restore patency). No further surgery was necessary in any of the patients with a silicon prosthesis.


CONCLUSIONS
When the advantages and disadvantages of the various procedures are considered, long-term splinting with a wide-lumened silicon prosthesis (Yamakava) appears to be a promising alternative to surgery for the treatment of benign biliary stenosis.
