Trial summary

The investigators hypothesize that the da Vinci Fluorescence Imaging Vision System provides real-time endoscopic near infrared fluorescence imaging of the biliary anatomy as defined as identifying biliary vessels; either cystic duct, common hepatic duct (CHD) or common bile duct (CBD).

About this study

Official title: A Prospective Investigation of the Use of the Fluorescence Imaging on the da Vinci Surgical System for Intra-operative Near Infrared Imaging of the Biliary Tree

The investigators hypothesize that the da Vinci Fluorescence Imaging Vision System provides real-time endoscopic near infrared fluorescence imaging of the biliary anatomy as defined as identifying biliary vessels; either cystic duct, common hepatic duct (CHD) or common bile duct (CBD). Irradiation given to the patient during a classic cholangiography can be reduced.

Read the detailed description

Up to 40 patients will be prospectively enrolled in this multi-centre (up to 5 centres) single arm study. After given consent, patients will undergo minimally invasive cholecystectomy with da Vinci Fluorescence Imaging using Indocynine green (ICG) and near infra-red light (NIR) to identify the surgically relevant anatomy of the biliary tree during this procedure.

Efficacy endpoints The efficacy of the da Vinci Fluorescence Imaging Vision System to identify biliary anatomy will be demonstrated by successful detection (90%) of one or more of the following biliary vessels: Cystic duct, common hepatic duct (CHD) or common bile duct (CBD).

Safety endpoints To observe and report peri-operative safety outcomes, including but not limited to incidence of adverse events and allergic reactions (rare according to the current knowledge and applications). Safety endpoints will be met by affirming the safety profile of the procedure, compared to currently available literature.

What participants receive

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

  • Indocyanine green (ICG)Drug

    2.5mg indocyanine green (ICG) will be administerly (IV injection) 30 minutes before surgery

Study groups in NCT01410734
Study groupRoleWhat they receive
ICGExperimentalPatient will received IV injection of ICG intra-operatively. Surgeon will view bile ducts under fluorescence imaging mode to see if ICG helps to identify biliary ducts.
Receives: Drug: Indocyanine green (ICG)

What is being measured

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

  1. To identify biliary anatomy will be demonstrated by successful detection (90%) of one or more of the following biliary vessels: Cystic duct, common hepatic duct (CHD) or common bile duct (CBD).

    Measured: intra-operatively

Secondary outcomes (1)
  1. observe and report peri-operative safety outcomes, including but not limited to incidence of adverse events and allergic reactions (rare according to the current knowledge and applications)

    Measured: within 2 weeks post-operatively

Questions about this trial

What is this clinical trial studying?

A study testing Indocyanine green (ICG) in people with Gallbladder Disease and Biliary Colic, run by Intuitive Surgical at 2 sites in 2 countries.

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 4 inclusion and 9 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 20 Dec 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Italy, 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?

To identify biliary anatomy will be demonstrated by successful detection (90%) of one or more of the following biliary vessels: Cystic duct, common hepatic duct (CHD) or common bile duct (CBD). (time frame: intra-operatively). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Dec 2012.
