    Abstract:
    PURPOSE: Near infrared cholangiography (NIRC) with indocyanine green (ICG) directly injected into the gallbladder is a novel technique to outline biliary anatomy. The purpose of this article is to analyze the usefulness and feasibility of NIRC as a safety method during laparoscopic cholecystectomies. MATERIAL AND METHODS: A case-controlled study comparing 20 patients undergoing laparoscopic cholecystectomies with NIRC with direct injection of ICG into the gallbladder to 20 consecutive standard cholecystectomies. Operative time, length of stay, complications, conversion rates, and biliary injury were analyzed. RESULTS: Both groups were comparable in epidemiological characteristics. In the ICG group fluorescent visualization of the junction of the Hartmann pouch and the whole cystic duct was achieved in 16 (80%) patients. Median surgical time was 65 (50-76) and 55 (45-71) min for the ICG and the control group, respectively (p = 0.113). There were no postoperative complications and no biliary duct injuries in any of the groups, and a patient from both groups underwent conversion to open surgery. CONCLUSION: NIRC with direct injection of ICG into the gallbladder is a feasible method that is not time-consuming; it does not require a different learning curve from standard laparoscopic cholecystectomies and has no major complications described so far.
