Near Infrared Fluorescence Cholangiography (NIRF-C) During Cholecystectomy -- Use in Acute Cholecystitis Sub-Study (NIRF-C Acute)
October 30, 2014 updated by: Narula, Vimal K, MD, Ohio State University
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
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.
|
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 will be performed intraoperatively in order to image anatomy.

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.
