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.

  • Stryker 10mm Ideal Eyes Laparoscope (0 and 30 degree)

Measure Description
Time Frame
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.
Injection to 2 wk follow-up
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.
Intraoperative
Procedure time
Time Frame: Intraoperative
The time it takes to perform near infrared fluorescence cholangiography and standard of care intraoperative cholangiography will be compared.
