Visualization of biliary ducts while doing laparoscopy, using HEV LapVision
Objective. To determine efficacy of intraoperative visualization of biliary tree, using fluorescent cholangiography (FCH) and a high–energy visible laparoscopy vison (HEV LapVison) while laparoscopic cholecystectomy performance (LCHE). Маterials and methods. In 25 patients LCHE was performed. Preoperatively fluorescein was injected intravenously for guaranteeing of the FCH performance. HEV LapVison was applied for intraoperative visualization of fluorescence. Results. Visualization of the cystic duct and its inflow into common biliary duct was guaranteed in 90% patientsх. In 13 (52%) patients the anatomic picture was typical while in 7 (28%) some variants were observed: a parallel course of cystic duct and common biliary duct, and low level of the cystic duct inflow into hepaticocholedochus. Conclusion. FCH is a simple procedure for intraoperative navigation doing and guaranteeing of «critical view on security» while performance of LCHE. FCH together with HEV LapVison constitutes a new surgical procedure, making possible revealing of extrahepatic biliary ducts. This method may be applied as additional one while doing LCHE, preventing damage of biliary ducts.
