Detection of the Common Bile Duct in Difficult Bile Duct Exploration Using Indocyanine Green Fluorescence Imaging: A Case Report.

We describe two cases using indocyanine green (ICG) fluorescence imaging for visualization of the common bile duct (CBD) in patients with difficult Bile duct exploration (BDE) due to extensive dense adhesions around the hepatoduodenal ligament. The CBD was rapidly detected under fluorescence guidance without excessive dissection of extensive dense adhesions. It is illustrated that the use of ICG fluorescence imaging is effective and feasible for detecting the CBD and thus we highly recommend this method during difficult BDE.
