Japanese paper just published where examined the use of Intraoperative indocyanine green (ICG) cholangiography to help avoid bile duct injuries.

Patients and Methods: We examined 25 patients who underwent intraoperative cholangiography using ICG fluorescence.

Results: There were 24 patients who underwent laparoscopic cholecystectomy and 1 patient who underwent hepatectomy. For laparoscopic cholecystectomy, the average operation time was 127 (50– 197) minutes, and estimated blood loss was 43.2 (0– 400) g. The ICG administration route was intravenous injections in 12 cases and intrabiliary injection in 12 cases (GB injection: 3 cases, PTGBD: 8 cases, ENBD:1 case). The postoperative hospital stay was 4.6 (3– 9) days, and no postoperative complications (Clavien–Dindo ≧IIIa) were observed. For hepatectomy, a tumor located near the left Glissonian pedicle was resected using a fluorescence image guide. Biliary structures were fluorescent without injury after resecting the tumor. No adverse events due to ICG administration were observed, and the procedure was able to be performed safely.

Conclusion: ICG fluorescence imaging allows surgeons to visualize the course of the biliary tree in real time during cholecystectomy and hepatectomy. This is considered essential for hepatobiliary surgery to prevent biliary tree injury and ensure safe surgery.
