Aim:
As an alternative method to the operative revision of benign bile duct strictures, we report the use of a large-bore bile duct prosthesis (Yamakawa prosthesis) in one patient.
Methods:
Bilateral percutaneous transhepatic implantation of Yamakawa prostheses (14 F right side, 12 F left side) was performed without adjunctive balloon dilatation. The prostheses were exchanged every 8 weeks under continuous antibiotic treatment and were finally removed after 8 months.
Results:
Control cholangiography showed a normal intrahepatic biliary system on the right side and a 50% stenosis at the orifice of the left hepatic duct. Follow-up over 18 months showed no signs of recurrent disease.
Conclusions:
In comparison to balloon dilatation and implantation of metallic stents, prolonged bilateral splinting with large-bore Yamakawa prostheses seems to be an alternative for the treatment of benign bile duct strictures.
