Registering the critical view of safety: photo or video?

Background One of the most important ways to reduce biliary duct injury in laparoscopic cholecystectomy is to achieve the critical view of safety (CVS) before transection of the cystic artery and duct. Documenting CVS is possible with photo prints, video imaging, or both. These documentations can be used as a proof of the right procedure in case of biliary duct injury, but only if the documentation is good enough to be judged independently by others.
