a

Clavien-Dindo grades are as follows: I, any deviation from the normal postoperative course without the need for pharmacologic treatment or surgical, endoscopic, and radiologic interventions; II, requiring pharmacologic treatment with drugs other than those allowed for grade I complications; III, requiring surgical, endoscopic, or radiologic intervention.
