Abstract:
We report on a laparoscopic cholecystectomy performed using the PINPOINT endoscopic fluorescence imaging system (Novadaq, Mississauga, ON, Canada), which enables surgery to be performed while simultaneously viewing fluorescent images. The patient was a 43-year-old man diagnosed with cholecystolithiasis. Indocyanine green (ICG) was administered 18h prior to surgery. The PINPOINT system made it possible to perform the procedure while viewing ICG fluorescence in the cystic duct. As the gallbladder was also imaged with this technique, it was easy to determine at which layer to detach the gallbladder from the liver bed. The operative time was 1h and 32min, and blood loss was 5ml. There were no perioperative complications.
