 Device: Biliary stent
Palliation of malignant biliary obstruction


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of patients without stent failure [ Time Frame: 12 months ]
    Number of patients without Stent failure (jaundice) or death with a patent stent


Secondary Outcome Measures :
  1. Overall survival [ Time Frame: 12 months ]
    Number of patietns alive in each group at 12 months

  2. Stent deployment failure [ Time Frame: During procedure ]
    Number of patients in whom there was failure to deploy the assigned stent(s) after randomisation

  3. Cost [ Time Frame: 12 months ]
    The differance in treatment costs between the two groups, measured in USD

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • 18years of age or older
  • informed consent obtained after oral and written information
  • clinical data in accordance with a malignant bile duct obstruction
  • imaging evidence: (ultrasonography (US), computed tomography (CT) or magnetic resonance imaging (MRI) shows signs of extrahepatic malignant common bile duct obstruction
  • typical ERCP findings of a malignant common bile duct stenosis
  • proximal margin of the bile duct stenosis ≥2 cm from the hepatic confluence
  • bilirubin > 50 micromol/L
  • radical surgery not deemed possible

Exclusion Criteria:

  • patients with active hepatitis or other jaundice-causing hepatic diseases
  • informed consent not obtained or patient unable to give informed consent
  • patients with no understanding of English, Afrikaans or Xhosa where it is not possible to obtain informed consent
  • metastasis with multiple significant intrahepatic stenosis causing blockage of one or more segments of the liver (liver metastasis otherwise not an exclusion criteria)
  • the patient is a possible candidate for surgical resection
  • suspicion of a non-malignant bile duct obstruction, e.g. stones or benign stenosis (should initiate further investigations)
  • the proximal end of the stenosis is < 2 cm from the hepatic confluence
  • previous BII or Roux-en-Y gastric reconstruction
  • significant duodenal obstruction making ERCP difficult
  • previous bile duct stent
