Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: uncovered double bare metallic stent (S&G Biotech.)
uncovered double bare metallic stent
Procedure: metallic biliary stent insertion (double bare - S&G Biotech.)
The patients who had malignant biliary obstruction will be enrolled our study. Enrolled patient will be randomized to three group (uncovered double bare metallic stent (S&G Biotech.) vs. uncovered single bare metallic stent (S&G Biotech.) vs. uncovered single bare metallic stent (Taewoong Medical.)). After metallic biliary stent insertion, enrolled patients will be followed at least one time per one month. Blood test (including total bilirubin, gamma-GT) will be done for follow-up study. During follow-up period, if biliary obstruction is suspected, imaging study (CT or MRCP) will be done. With such follow-up tools, we compare 6-month patency rate and median patency duration among three groups.
