Brief Summary
The purpose of this prospective, randomized multicenter study is to determine whether there is any difference in stent patency of covered metallic stents in terms of stent positioning, above and across the sphincter of Oddi, in malignant bile duct obstruction.

Outcome Measures
Primary Outcomes (1)
Obstruction of 1st C-SEMS or presence of jaundice at death without stent exchange
one year
Secondary Outcomes (1)
Death of patients
one year
Study Arms (2)
Group A: C-SEMS, inserted above SO
ACTIVE COMPARATOR-In group A, SO should be preserved without sphincterotomy, but small infundibulotomy with needle knife can be accepted for cannulation.
Group B: C-SEMS, inserted across SO
ACTIVE COMPARATOR-In group B, small sphincterotomy (50% incision) will be done after biliary cannulation.
Interventions
The stent is made of Nitinol wire. It is a flexible, fine mesh tubular prosthesis and it has 10 radiopaque markers; 4 in each end and 2 in the center.
Eligibility Criteria
You may qualify if:
- Inoperable and/or unresectable cases of malignant stenosis at distal common hepatic duct or CBD, \>= 18 years old
- Bile duct or gallbladder cancer invading CBD or distal CHD
- Pancreatic cancer with mid or distal CBD invasion
- Cancer should be 1.5 cm apart from bifurcation and 2 cm apart from ampulla of Vater.
- First attempt of endoscopic biliary metallic stenting
- Negative history of biliary tract surgery
- Life expectancy at least longer than 4 months (Karnofsky score \>60%)
You may not qualify if:
- Ampullary cancer
- Klatskin tumor
- Combined intrahepatic bile duct cancer
- Patient with hemobilia
- Previous history of biliary drainage (endoscopic, percutaneous, surgical) except plastic stent or endoscopic nasobiliary drainage smaller than 7 Fr within 14 days
