Thoracic Surgery Department (TSD) of the Surgical Clinic of the University of Debrecen has once again received accreditation from the European Society of Thoracic Surgeons (ESTS), confirming that this institution provides European-level care to patients. TSD first earned this prestigious international certification back in 2012, becoming the first such institution in Eastern Europe to do so. Since then, the certificate has had to be reearned every five years based on strict criteria.
