In the era of
precision medicine, compared with open
surgery, laparoscopic cholecystectomy has the advantages of less
trauma, less
postoperative complications and shorter
hospital stay, but it cannot escape the
risk of
bile duct injury, and
bile duct injury can occur at any
time for various reasons, and its unpredictability greatly increases the difficulty of
surgery. Although traditional
cholangiography can avoid
bile duct injury, it has not been widely used due to its limitations such as
time consuming, high
cost, high
radiation and so on. Early
indocyanine green has been widely used in
lymph node examination,
angiography,
tumor localization and
treatment due to its characteristics. Now, indocyane green
fluorescence imaging technology has been gradually applied in LC, which can dynamically reflect the intraoperative situation and realize real-
time surgical navigation, so it has achieved ideal effects in the identification of duct structure and prevention of
bile duct injury.
Indocyanine green injection preoperatively or intraoperatively through the
gallbladder to develop
extrahepatic bile ducts significantly improves the
safety rate of
surgery, but there is no unified standard for the use
time and
dosage of inddocyanine green. In this
paper, the
time and
dose selection and clinical value of
indocyanine green were reviewed based on the current
research status and the author's experience.
