CVS
Pronunciation: see-vee-ess
Also written as: CVS — Critical View of Safety
Critical view of safety, a laparoscopic landmark ensuring safe identification of structures before cholecystectomy.
Full Definition
Critical view of safety is a standardized laparoscopic technique for ensuring safe cholecystectomy by achieving clear visualization of key anatomical structures. CVS requires three criteria: clear view of Calot triangle with only two structures crossing to the gallbladder (cystic artery and cystic duct), clear view of the liver bed, and no other structures in Calot triangle. This technique, popularized by Steven Strasberg, significantly reduces the risk of bile duct injury during laparoscopic cholecystectomy.
Usage
Usage note: Always spell out on first use; essential safety concept in laparoscopic cholecystectomy.
