Achieving the critical view of safety in the difficult laparoscopic cholecystectomy: a prospective study of predictors of failure

Abstract

All three components of the critical view of safety could not be demonstrated in one out of 6 consecutive laparoscopic cholecystectomies. Preoperative factors and operative difficulty grading can predict cases where the CVS may not be achievable. Adapting instrument selection and alternate dissection strategies would then need to be considered.
