Background and Study Aims: In a previous study evaluating the problems of long-term percutaneous transhepatic biliary drainage (PTBD) using Yamakawa-type prostheses in patients with benign and malignant stenoses, breakage of the tube proved to be a serious problem, occurring in 19.7 % of PTBD exchanges. As a consequence of these results, a new PTBD tube made of Tecothane has been developed.

Patients and Methods: From September 1997 to September 1998, this new PTBD tube was applied in 64 patients (39 men, 25 women; median age: 70, range 29 - 89) in the treatment of benign (n = 30) or malignant stenoses (n = 31; three stenoses remained indeterminate), and the course was followed.

Results: A total of 134 stent exchanges were performed, 52 of these being ahead of schedule (39 %). Not a single case of breakage occurred. However, other PTBD-related problems remained unchanged. Patients accepted the new prosthesis very well; among 19 patients who had experience of both the new one and the conventional one, 11 had preferences - eight for the new one and three for the old one.

Conclusions: This new Tecothane prosthesis has solved the problem of PTBD breakage, which was often accompanied by serious problems. As was to be expected, other PTBD-related problems were not substantially affected. Nevertheless, this new tube represents progress in the percutaneous treatment of biliary stenoses.
