Trial summary

Patients with gallstone disease should be checked whether a common bile duct (CBD) stone could be present. In case of a certain suspicion for CBD stones further investigations should be performed. This can either be done by magnetic resonance cholangio-pancreaticography (MRCP) or by intraoperative cholangiography. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients presenting as regular admission or at the emergency department (ED) with cholecystolithiasis and suspected CBD stones. The indication for CBD investigation requires one of the following features:
  • Elevated bilirubin ii. ASAT/ALAT or gGT or aP above the normal range (two of them) iii. Choledocholithiasis in ultrasound iv. Dilated bile ducts in ultrasound
  • Written informed consent

Who cannot join

  • Age under 18 years
  • Patients with biliary pancreatitis (due to the fact that conservative treatment is initiated before gallbladder removal and therefore leads to a prolonged hospital stay)
  • Septic patients due to cholangitis
  • Patients unable to consent
  • Patients with medical conditions preventing surgery
  • Pregnancy
  • Radiologically proven CBD stone

About this study

Official title: Diagnostic Pathway for Surgical Patients With Suspected Bile Duct Obstruction

Patients with gallstone disease should be checked whether a common bile duct (CBD) stone could be present. In case of a certain suspicion for CBD stones further investigations should be performed. This can either be done by magnetic resonance cholangio-pancreaticography (MRCP) or by intraoperative cholangiography. The study investigates which pathway would be favorable in regard of an early hospital demission.

Read the detailed description

Patients with gallstone disease and suspected bile duct obstruction can be investigated either with a magnetic resonance cholangio-pancreaticography (MRCP) prior to gallbladder removal or with an intraoperative cholangiography during cholecystectomy. When detecting an common bile duct (CBD) stone in MRCP, normally endoscopic removal is performed before an operation. When the CBD stone is detected during gallbladder removal instead, endoscopic retrograde cannulation of the pancreatic duct (ERCP) will follow after the operation. Investigators hypothesize that direct operation shortens the length of hospital stay. Therefore investigators randomize patients with elevated Bilirubin, elevated liver enzymes (two of the following: aspartate transaminase (ASAT), alanine aminotransferase (ALAT), gamma-glutamyltransferase (gGT) or AP), suspected CBD stones in ultrasound or dilated common bile ducts either in MRCP first or operation first pathway. All data (patient admission to discharge, ...) will be entered in an online database

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cholecystectomy and intraoperative cholangiographyProcedure or surgery

    Also called IOC

    Patients with suspected bile duct obstruction intraoperative cholangiography IOC to investigate bile ducts.

  • Magnet resonance cholangio-pancreaticographyProcedure or surgery

    Also called MRCP

    Patients get Magnet resonance cholangio-pancreaticography MRCP first. In case of detected gallstones, removal of the stones by endoscopic retrograde cholangiopancreaticography will be performed before gallbladder removal.

  • magnet resonance imagingDevice

    Also called MRI

    Patients get Magnet resonance cholangio-pancreaticography MRCP first. In case of detected gallstones, removal of the stones by endoscopic retrograde cholangiopancreaticography will be performed before gallbladder removal.

  • catheterDevice

    Patients with suspected bile duct obstruction intraoperative cholangiography IOC to investigate bile ducts.

What is being measured

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

  1. Length of Hospital stay

    Time of hospital entry to time of patient dischargeable, according to stuff surgeon. Dates will be entered in an online database, which is also used for randomisation.

    Measured: number of days patient spent in hospital assessed at discharge day, on average 8 days

Secondary outcomes (1)
  1. Costs of Hospital stay

    Computed by the financial departments of each involved hospital

    Measured: days in hospital assessed at hospital discharge day, on average 8 days

Questions about this trial

What is this clinical trial studying?

A study testing Cholecystectomy and intraoperative cholangiography, Magnet resonance cholangio-pancreaticography and magnet resonance imaging in people with Gallstone Disease, run by University Hospital, Basel, Switzerland at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Length of Hospital stay (time frame: number of days patient spent in hospital assessed at discharge day, on average 8 days). 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 NCT02351492, which also lists 1 linked publication.

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 8 Dec 2022.
