Abstract | PURPOSE: To present our clinical experience and to suggest different strategies in the management of dysfunctioning plastic biliary stents in patients with malignant biliary obstruction. MATERIALS AND METHODS: RESULTS: Forty-nine of the dysfunctioning plastic stents were cleared from the biliary tree. Of these, 31 were dislodged into the bowel with the help of a balloon catheter. Threading with an over-the-wire diagnostic and percutaneous biliary drainage catheter was performed in 12 of the plastic stents. Six dysfunctioning endoprostheses were removed by transhepatic access. Three plastic endoprostheses could not be removed or dislodged. No complication occurred due to intervention. The mean follow-up time was nine months (range, 1-19 months). All of the patients were evaluated in the first month, and then at three-month intervals. Percutaneous metallic stenting was performed on 29 patients. CONCLUSION: Percutaneous intervention should be considered as an alternative treatment when a need for eliminating the dysfunctioning plastic stent arises. Both removal of the dysfunctioning stent and dislodgement into the bowel are safe and efficient strategies in the management of malignant biliary obstructions.
