Fluorescent Cholangiography vs White Light for Bile Ducts Identification

Detailed Description
Recently, a novel technique to visualize structures using fluorescent light and intravenous dye has been developed.
Near Infrared Incisionless Fluorescent Cholangiography (NIFC) is a medical imaging technique that uses fluorescence to detect properly labeled structures during surgery.
NIFC is performed using imaging devices with the purpose of providing real-time simultaneous information from color reflectance images (white light) and fluorescence emission (near infrared light). One or more light sources are used to excite and illuminate the sample. Light is collected using optical filters that match the emission spectrum of the fluorophore. Imaging lenses and digital cameras are used to produce the final image.
During laparoscopic cholecystectomies, the visualization of the extra-hepatic bile ducts with fluorescence is called Near Infrared Incisionless Fluorescent Cholangiography (NIFC). Fluorescence equipment and a dye are necessary in order to perform a NIFC, but the technique requires no radiation or incision. A fluorescence dye is administrated intravenously at least 45 minutes before the surgery, which is excreted by the liver and the bile duct The Study is designed to compare the effectiveness of Near Infrared Fluorescence Cholangiography (NIFC) to standard white light imaging (WLI) in visualizing and identifying the main biliary and hepatic structures (Cystic Duct, Right Hepatic Duct, Common Hepatic Duct, Common Bile Duct, Cystic-CBD junction, Cystic-Gallbladder junction and any Accessory Ducts) during laparoscopic cholecystectomy.
Eligible patients will be identified through clinical and test evaluation. Eligibility will be verified by the patient's primary surgeon. The surgeon will determine the indication and date of the surgery. Once a patient is confirmed as eligible, the surgeon will introduce the study in detail. If after being introduced to the study and having had the opportunity to ask questions, the patient is willing to participate, he/she will be asked to review and sign the informed consent document .
Upon entry in the clinical trial patients will be randomly allocated to the intervention arm. Data will be collected at enrolment time, during surgery, at the end of surgery and one week after surgery.
Upon entry in the clinical trial, the master study database (REDCap, will randomly allocated patients to one of the study arms (1:1) within site (1:1) using a computer generated random sequence. This will provide an allocation sequence for each site. Once a patient is enrolled and a database file in REDCap is initiated for that patient, he/she will be assigned electronically to one of the study arms.
Patient will be blind to the intervention but surgeon blinding will not be feasible due to the nature of the intervention. The study will involve a considerable number of surgeons in each site, which should compensate any potential bias of some of them in favor or against either approach.

Plan for Individual participant data (IPD)
Plan to Share Individual Participant Data (IPD)?
IPD Plan Description
Redcap will be used Data to be shared - pre-operative data including age, sex, laboratory values and imaging, intra-operative data including visualization of the extra-hepatic biliary structure with white light and with infrared light by the operating surgeon and the observer, any bile leak; post-operative data documenting any complications such as reaction to ICG or bile duct injury.
Data will be available as each center finishes up the follow of each individual patient (usually 2 weeks post operatively). Each center will update the data on Redcap on a monthly basis.
Data will be initially obtained on a pre-decided forms (approved by the IRB committee) and transferred to Redcap for electronic record keeping and analysis.
