|Official Title:||Near Infrared Fluorescence Cholangiography (NIRF-C) During Cholecystectomy Sub-Study|
|Study Start Date :||July 2013|
|Primary Completion Date :||August 2014|
|Study Completion Date :||August 2014|
Experimental: NIRF-C and IOC
Each enrolled subject will undergo injection with indocyanine green (ICG), intraoperative near infrared fluorescence cholangiography (NIRF-C) and standard of care intraoperative cholangiography.
Drug: Indocyanine Green (ICG)
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.Device: Near Infrared Fluorescence Cholangiography (NIRF-C)
Near infrared fluorescence cholangiography will be performed intraoperatively in order to image anatomy.
- Adverse events related to use of indocyanine green (ICG) [ Time Frame: Injection to 2 wk follow-up ]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.
- Anatomic identification with NIRF-C and IOC [ Time Frame: Intraoperative ]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.
- Procedure time [ Time Frame: Intraoperative ]The time it takes to perform near infrared fluorescence cholangiography and standard of care intraoperative cholangiography will be compared.
