Interest of Intravenous Cholangiography With Indocyanine Green in the Context of Laparoscopic Cholecystectomy for Grade 1 and 2 Acute Gallstone Cholecystitis
Interest of Intravenous Cholangiography With Indocyanine Green in the Context of Laparoscopic Cholecystectomy for Grade 1 and 2 Acute Gallstone Cholecystitis
Acute lithiasis cholecystitis (ALC) is the third most common cause of surgical emergency
 admission. The initial treatment of ALC associates a medical support and a cholecystectomy,
 preferentially performed laparoscopically in the first 5 days of evolution. During the
 surgery, intraoperative cholangiography (CPO) using a contrast product is the "gold standard"
 to identify the bile ducts. However CPO is performed in approximately 30% of laparoscopic
 cholecystectomy.

 Laparoscopic cholecystectomy for ALC is associated with an increase in the rate of biliary
 ducts injuries compared with cholecystectomy for symptomatic vesicular lithiasis, evaluated
 at 0.8 % versus 0.1 %. Its higher rate is related to local inflammation that alters the
 biliary anatomy and complicates the identification of the bile ducts. Indocyanine green
 facilitates the visualization of extrahepatic biliary structures, which could reduce the risk
 of biliary wound and shorten the operating time.
