About this study

Official title: Fluorescence Cholangiography Versus Conventional Intraoperative Cholangiography for Visualization of Biliary Tract Anatomy : a Prospective, Controlled Study

The burden of iatrogenic bile duct injury (BDI), the most feared complication of laparoscopic cholecystectomy (LC), is extremely high and the repercussions on the patient's outcomes may be severe ranging from intraoperative repair to liver transplant or patient's death. Different techniques have been proposed to prevent BDI.

Our hypothesis is that a fluorescence-based Imaging would allow visualization of the biliary tree anatomy as good as with the Intraoperative Cholangiogram with several main advantages:

Read more
  1. ease of use
  2. lack of invasiveness
  3. absence of ionizing radiation to the patient and the operating staff
  4. performed prior to any dissection (prior to "critical view of safety")

Capacity of enhanced-reality based on virtual cholangiography (computer treatment of MRI images) to guide biliary tree anatomy visualization will be also evaluated in this study.

The study requires a 2-month patient participation.

What participants receive

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

  • Fluorescence cholangiography (da Vinci surgical system)Device

    Also called da Vinci Si surgical system with da Vinci Fluorescence Imaging Vision System

    Patients will received IV injection of ICG intra-operatively, allowing surgeons to view bile ducts under fluorescence imaging using the da Vinci surgical system with fluorescence Imaging system.

  • Virtual cholangiographyOther

    Images from virtual cholangiography will be superimposed in real time on images obtained with fluorescence.

  • Conventional IOCProcedure or surgery

    Patients will undergo conventional intraoperative cholangiography (with use of radio-opaque dye), allowing surgeons to view bile ducts under Rx imaging.

Study groups in NCT01881399
Study groupRoleWhat they receive
Fluorescence/Virtual cholangiography/IOCExperimentalPrior to cholecystectomy, patients will undergo: * Fluorescence cholangiography (visualization following up to a maximum of 0.5 mg/kg ICG - usually 10 ml of 0,5 mg/ml solution) * Virtual cholangiography (enhanced-reality) superimposed on fluorescence images * Conventional IOC (intraoperative cholangiography)
Receives: Device: Fluorescence cholangiography (da Vinci surgical system); Other: Virtual cholangiography; Procedure: Conventional IOC

What is being measured

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

  1. To evaluate the ability of a ICG-fluorescence guidance in visualizing the biliary anatomy and to compare accuracy to conventional intraoperative cholangiography

    Percentage of patients for whom fluorescence allows for cysticocholedochal junction with precision at least as good as intraoperative cholangiography (identification of anatomical details and information).

    Independent aposteriori evaluation performed by a radiologist/surgeon team.

    Measured: Intra-operatively

Secondary outcomes (3)
  1. To evaluate the ability of fluorescence-based imaging in visualizing the biliary tree anatomy

    Percentage of patients for whom fluorescence-based imaging allows correct identification of biliary tree anatomy (anatomical variant, cystic duct stones, bile duct stones, dilated ducts)

    Measured: Intra-operatively

  2. To evaluate the ability of enhanced reality in visualizing the biliary anatomy intra-operatively, especially the cysticocholedochal junction

    Percentage of patients for whom enhanced reality allows correct identification of biliary tree anatomy,especially the cysticocholedochal junction

    Measured: Intra-operatively

  3. To evaluate time required for the visualization of biliary tree anatomy for each modality : fluorescence, enhanced reality, conventional intraoperative cholangiography

    Time required for fluorescence-based exam, enhanced reality visualization, conventional intraoperative cholangiography Conversion to costs (based on mean cost of OR minute)

    Measured: Intra-operatively

Questions about this trial

What is this clinical trial studying?

A study testing Fluorescence cholangiography (da Vinci surgical system), Virtual cholangiography and Conventional IOC in people with Cholelithiasis and Gallbladder Polyps, run by IHU Strasbourg at 1 site in France.

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 12 inclusion and 2 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 14 Mar 2018. 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 France. 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?

To evaluate the ability of a ICG-fluorescence guidance in visualizing the biliary anatomy and to compare accuracy to conventional intraoperative cholangiography (time frame: Intra-operatively). 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 NCT01881399, 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 14 Mar 2018.
