Clavien-Dindo classification

Pronunciation: KLAH-vee-en DIN-doh

Standardized grading system for surgical complications based on treatment requirements.

Full Definition

The Clavien-Dindo classification is a widely accepted standardized system for grading surgical complications based on the therapeutic intervention required to treat the complication. Grade I complications require no treatment or only bedside interventions; Grade II requires pharmacological treatment; Grade III requires surgical, endoscopic, or radiological intervention (IIIa without general anesthesia, IIIb with general anesthesia); Grade IV represents life-threatening complications requiring intensive care; and Grade V indicates patient death. This classification enables consistent reporting and comparison of surgical outcomes across institutions and studies.

Usage

Usage note: Always include the specific grade (I-V) with subclassifications when applicable.
