ABSTRACT
BACKGROUND:
Intraoperative incisionless fluorescent cholangiogram (IOIFC) has been demonstrated to be a useful tool to increase the visualization of Calot's triangle. This study evaluates the identification of extrahepatic biliary structures with IOIFC by medical students and surgery residents.METHODS:
Two pictures were taken, one with xenon light and one with near-infrared (NIR) light, at the same stage during dissection of Calot's triangle in ten different cases of laparoscopic cholecystectomy (LC). All twenty pictures were organized in a random fashion to remove any imagery bias. Twenty students and twenty residents were asked to identify the biliary anatomy.RESULTS:
Medical students were able to accurately identify the cystic duct on an average 33.8 % under the xenon light versus 86 % under NIR light (p = 0.0001), the common hepatic duct (CHD) on an average 19 % under the xenon light versus 88.5 % under NIR light (p = 0.0001), and the junction on an average 24 % under xenon light versus 80.5 % under NIR light (p = 0.0001). Surgery residents were able to accurately identify the cystic duct on an average 40 % under the xenon light versus 99 % under NIR light (p = 0.0001), the CHD on an average 35 % under the xenon light versus 96 % under NIR light (p = 0.0001), and the junction on an average 24 % under the xenon light versus 95.5 % under NIR light (p = 0.0001).CONCLUSIONS:
IOIFC increases the visualization of Calot's triangle structures when compared to xenon light. IOIFC may be a useful teaching tool in residency programs to teach LC.Palavras-chave
