The Clavien-Dindo classification is validated for worldwide use in surgery, recommending the removal of subjective terms like 'minor or major' from the surgical literature.
This 5-year evaluation provides strong evidence that the classification is valid and applicable worldwide in many fields of surgery. No modification in the general principle of classification is warranted in view of the use in ongoing publications and trials. Subjective, inaccurate, or confusing terms such as "minor or major" should be removed from the surgical literature.
Clavien et al. (2009) studied this question.
