| [ Summary ] | Biliary stenting for malignant hilar biliary obstructions is controversial. Endoscopic biliary drainage has become the first choice treatment for maintaining quality of life. However, there are many different opinions among clinical technicians concerning questions involved. These questions include how many stents should be placed (unilaterally or bilaterally), and which stents are most suitable (metallic stents or plastic stents). Bilateral biliary drainage of metallic stents for unresectable malignant hilar biliary obstruction can be performed with stent-in-stent or side-by-side techniques. Both the stent-in-stent and side-by-side techniques have their own merits and problems. Bilateral metallic stent placement has been achieved in most of cases with new improvements in metallic stents. | |
