SUMMARY Background: Evaluation of the efficacy of the percutaneous transhepatic insertion of metallic endoprothesis in 53 patients with biliary obstruction. Materials and methods: From September 1994 to December 2001, 83 patients with obstructive jaundice, 79 with malignancy and 4 with benign obstruction, aged 29-92 years (mean age 67,3 years), attended the Radiology Department of our hospital. In 3 patients, the findings of percutaneous cholangiography did not indicate any further access. 68 metallic stents were implanted in 53 out of the 80 remaining patients, whereas the other 27 patients were treated with percutaneous biliary drainage: external drainage was performed in 21 patients in order to assist a following operation, and a combined internal-external drainage in 6 patients. Hemobilia occured in one patient and required embolization of the right hepatic artery. In 5 cases a new procedure was needed because of the occlusion of the endoprotheses after 40-278 days. Results: Clinical improvement and decrease in serum bilirubin levels was achieved in all patients. The survival time in patients with malignancy ranged between 6 to 485 days (mean survival time 139 days). Obviously, the patients who were treated with implantation of an endoprothesis had a better quality of life in comparison to those treated only with external or internal-external drainages and were not subsequently operated. Conclusion: The percutaneous transhepatic insertion of metallic stents is proved to be an efficient and secure method of biliary obstruction treatment, particularly in malignant inoperable cases. Key-words: metallic endoprothesis - biliary obstruction - percutaneous drainage (EN)
