About this study

Official title: Multinational Study on Endoscopic Management of Distal Malignant Biliary Obstruction Combined With Gastric Outlet Obstruction

This is a retrospective study to evaluate the outcomes of endoscopic biliary drainage according to the timing of distal malignant biliary obstruction (MBO) in relation to gastric outlet obstruction (GOO) and the location of GOO.

Read the detailed description

This is a multinational multicenter retrospective cohort study to evaluate the outcomes of endoscopic biliary drainage in patients with a duodenal SEMS. Endoscopic ultrasound-guided biliary drainage (EUS-BD), including choledochoduodenostomy, hepaticogastrostomy, antegrade biliary stenting or a combination, and endoscopic retrograde cholangiopancreatography (ERCP) with stenting are to be compared. Specifically, the outcomes are to be evaluated according to the timing of distal MBO in relation to GOO and the location of GOO.

EUS-BD or ERCP with duodenal SEMSPatients who underwent endoscopic placement of a duodenal self-expandable metal stent (SEMS) for nonresectable malignant GOO and endoscopic biliary drainage for nonresectable distal MBO.
Receives: Procedure: Biliary drainage

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to recurrent biliary obstruction

    Recurrent biliary obstruction is defined as a composite endpoint of either occlusion or migration of biliary stent, and time to recurrent biliary obstruction is time from biliary drainage to recurrence of biliary obstruction.

    Measured: Up to 1 year

Secondary outcomes (4)
  1. Causes of recurrent biliary obstruction

    Causes of recurrent biliary obstruction include sludge, food impaction, ingrowth, tumor overgrowth, hemobilia and others.

    Measured: Up to 1 year

  2. Functional success rate of biliary drainage

    Functional success is defined when bilirubin decreases < 50% or is normalized within 2 weeks.

    Measured: 2 weeks

  3. Procedure-related complication of biliary drainage and duodenal meta stent placement (type and severity)

    Complications and their severity are determined using the American Society of Gastrointestinal Endoscopy guidelines.

    Measured: 30 days

  4. Survival time

    Survival time is defined as the period between biliary stent placement and death.

    Measured: Up to 2 year

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to recurrent biliary obstruction (time frame: Up to 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02376907, which also lists 10 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2015.
