This illustration depicts a key surgical moment from a robot-assisted cholecystectomy. In this procedure, the cystic duct and cystic artery are clipped and divided in order to remove the gallbladder. Figure 4a shows the critical view of safety, where the gallbladder has been partially mobilized and the surface of the liver is visible between the cystic duct and artery. Observation of the critical view of safety prevents accidental clipping of the surrounding biliary tree and arteries, which are ghosted in. Figure 4b shows the subsequent division of the cystic duct and artery. This piece was designed for slide format.
