Easier intraoperative recognition of the biliary anatomy may be accomplished by using near-infrared fluorescence (NIRF) imaging after an intravenous injection of indocyanine green (ICG). Promising results were reported for successful intraoperative identification of the extrahepatic bile ducts compared to conventional laparoscopic imaging. However, routine use of ICG fluorescence laparoscopy has not gained wide clinical acceptance yet due to a lack of high-quality clinical data. Therefore, this multicentre randomised clinical study was designed to assess the potential added value of the NIRF imaging technique during LC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>A multicentre, randomised controlled clinical trial will be carried out to assess the use of NIRF imaging in LC. In total, 308 patients scheduled for an elective LC will be included. These patients will be randomised into a NIRF imaging laparoscopic cholecystectomy (NIRF-LC) group and a conventional laparoscopic cholecystectomy (CLC) group. The primary end point is time to \u2018critical view of safety\u2019 (CVS). Secondary end points are \u2018time to identification of the cystic duct (CD), of the common bile duct, the transition of CD in the gallbladder and the transition of the cystic artery in the gallbladder, these all during dissection of CVS\u2019; \u2018total surgical time\u2019; \u2018intraoperative bile leakage from the gallbladder or cystic duct\u2019; \u2018bile duct injury\u2019; \u2018postoperative length of stay\u2019, \u2018complications due to the injected ICG\u2019; \u2018conversion to open cholecystectomy\u2019; \u2018postoperative complications (until 90\u2005days postoperatively)\u2019 and \u2018cost-minimisation\u2019.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>The protocol has been approved by the Medical Ethical Committee of Maastricht University Medical Center\/Maastricht University; the trial has been registered at ClinicalTrials.gov.
