Application of fluorescent cholangiography during single-incision laparoscopic cholecystectomy in the cystohepatic duct without preoperative diagnosis

Application of fluorescent cholangiography to complex biliary variants of the confluence of the cystic duct and the infraportal type of the left lateral bile duct during single-incision laparoscopic cholecystectomy: A case report

A 21-year-old man was diagnosed with segmental adenomyomatosis of the gallbladder based on ultrasonography and computed tomography images. Computed tomography with drip infusion cholangiography revealed that the cystic duct joined the infraportal type of the left lateral bile duct (IPLLBD), which runs caudal to the umbilical portion, and that the left medial bile duct joined the right hepatic duct without forming the left hepatic duct. We planned a single-incision laparoscopic cholecystectomy with fluorescent cholangiography. The fluorescent cholangiography visualized the anatomic variant of the biliary system, and the cystic duct was divided safely. Fluorescent cholangiography is a suitable procedure to depict complex biliary anatomic variations in this patient. IPLLBD without the formation of the left hepatic duct is potentially hazardous during cholecystectomy.

Fluorescent cholangiography: An up-to-date overview twelve years after the first clinical application

Laparoscopic cholecystectomy (LC) is one of the most frequently performed gastrointestinal surgeries worldwide. Bile duct injury (BDI) represents the most serious complication of LC, with an incidence of 0.3%-0.7%, resulting in significant perioperative morbidity and mortality, impaired quality of life, and high rates of subsequent medico-legal litigation. In most cases, the primary cause of BDI is the misinterpretation of biliary anatomy, leading to unexpected biliary lesions. Near-infrared fluorescent cholangiography is widely spreading in clinical practice to delineate biliary anatomy during LC in elective and emergency settings. The primary aim of this article was to perform an up-to-date overview of the evolution of this method 12 years after the first clinical application in 2009 and to highlight all advantages and current limitations according to the available scientific evidence.
