Brief Summary

The current study shows that Indocyanine green (ICG)-fluorescence cholangiography can be useful in identifying the extrahepatic biliary anatomy during Calot's triangle dissection. By avoiding hepatic fluorescence, the transhepatic intracholecystic-ICG route can increase the bile duct-to-liver contrast with less expense and no risk of hypersensitivity reactions than the intravenous ICG injection method. We recommend to use both techniques in case of acute cholecystitis with cystic duct obstruction. In cases of liver cirrhosis, we recommend transhepatic IC-ICG as IV-ICG is limited.

Outcome Measures

Primary Outcomes (1)

  • The rate of better delineation of the biliary tree during laparoscopic cholecystectomy

    To detect the safety, efficacy, feasibility and accuracy in defining the biliary anatomy during laparoscopic cholecystectomy.

    intraoperative and 2 weeks postoperative

Study Arms (2)

Intravenous Injection Injection of Indocyanine Green (ICG)

ACTIVE COMPARATOR

7.5 mg (3 ml of a 25 mg/10 ml solution) of indocyanine green was injected intravenously in the pre-operative holding area at least 20 minutes before surgery to outline the biliary tree during laparoscopic cholecystectomy.

Drug: Indocyanine Green

Transhepatic intracholecystic injection of Indocyanine Green (ICG)

ACTIVE COMPARATOR

Intracholecystic injection of ICG was done in 30 patients. Twenty 1.25 mg particles, one from a 25 mg ICG vial, were separated under aseptic conditions.

Drug: Indocyanine Green Drug

Interventions

injecting 7.5 mg (3 ml of a 25 mg/10 ml solution) intravenously in the pre-operative holding area at least 20 minutes before surgery. Before dissecting the adhesions surrounding the hepatoduodenal ligament, fluorescence cholangiography (FC) is carried out to determine the anatomy of the extrahepatic bile ducts by converting the full-color images to fluorescence images using filter switches on the camera head and/or light source in the laparoscopic imaging system (Fig. 1). The \"critical view of safety\" is then reached by dissecting Calot\'s triangle and using FC to verify whether the accessory bile ducts are present or absent throughout the procedures. It is necessary to acquire fluorescence image

Intravenous Injection Injection of Indocyanine Green (ICG)

1.25 mg of ICG powder was dissolved in 3 cm of saline, and the concentration was roughly 0.04 mg after each 1 cm of saline was diluted by 9 cm of saline. In order to prevent dye leakage that might result in false FC results, a veress needle was inserted through the abdominal wall and into the gall bladder fundus through the liver bed. The puncture site was then cauterized.
