critical view of safety
Also written as: CVS
A standardized anatomical landmark system used in laparoscopic cholecystectomy to prevent bile duct injury.
Full Definition
The critical view of safety is a fundamental safety concept in laparoscopic cholecystectomy that requires identification of three specific criteria before dividing any structures: clear visualization of only two structures entering the gallbladder (cystic artery and cystic duct), clearing of all tissue from Calot's triangle except these two structures, and clear identification of the liver bed. This systematic approach has significantly reduced the incidence of bile duct injuries, which represent the most serious complication of laparoscopic cholecystectomy.
Usage
Usage note: Capitalize when referring to the formal concept; lowercase in general usage.
