About this study
Official title: Near Infrared Fluorescence Cholangiography (NIRF-C) During Cholecystectomy Sub-Study
The purpose of this study is to evaluate an imaging system using Indocyanine Green (ICG) to assist in real-time identification of anatomy during cholecystectomy (gallbladder removal) in patients with acute cholecystitis and cholangitis. We propose to define the effectiveness of NIRF-C in identifying the cystic duct junction during cholecystectomy.

- Acute Cholecystitis, Acute Cholangitis
- Being tested
- Indocyanine Green (ICG), Near Infrared Fluorescence Cholangiography (NIRF-C)
- Keywords

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Indocyanine Green (ICG)Drug
60-30 minutes prior to cholecystectomy, 2.5 mg of indocyanine green (ICG) will be injected intravenously. An additional 2.5 mg of ICG may be injected intraoperatively if the fluorescence fades prior to imaging.
Near Infrared Fluorescence Cholangiography (NIRF-C)Device
Also called Stryker 1488 Camera System, Stryker L9000 Light Source, Stryker 1488 Coupler, Stryker 10mm Ideal Eyes Laparoscope (0 and 30 degree)
Near infrared fluorescence cholangiography will be performed intraoperatively in order to image anatomy.
| Study group | Role | What they receive |
|---|---|---|
| NIRF-C and IOC | Experimental | Each enrolled subject will undergo injection with indocyanine green (ICG), intraoperative near infrared fluorescence cholangiography (NIRF-C) and standard of care intraoperative cholangiography. Receives: Drug: Indocyanine Green (ICG); Device: Near Infrared Fluorescence Cholangiography (NIRF-C) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Adverse events related to use of indocyanine green (ICG)
Adverse events related to the use of ICG from the time of injection through the initial post-operative clinic visit will be recorded and assessed.
Measured: Injection to 2 wk follow-up
Anatomic identification with NIRF-C and IOC
Anatomic identification with near-infrared fluorescence cholangiography and standard of care intraoperative cholangiography (IOC) will be used to calculate a 95% confidence interval for the effectiveness of this modality.
Measured: Intraoperative
Procedure time
The time it takes to perform near infrared fluorescence cholangiography and standard of care intraoperative cholangiography will be compared.
Measured: Intraoperative

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Indocyanine Green (ICG) and Near Infrared Fluorescence Cholangiography (NIRF-C) in people with Acute Cholecystitis and Acute Cholangitis, run by Ohio State University at 1 site in United States.
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 2 inclusion and 4 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 3 Nov 2014. 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 United States. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Adverse events related to use of indocyanine green (ICG) (time frame: Injection to 2 wk follow-up). The study lists 3 primary outcomes in all. 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 3 Nov 2014; AzTrials last refreshed its copy on 7 Nov 2026.
