Abstracts 23rd European Conference on General Thoracic Surgery 31 May–3 June 2015, Lisbon, Portugal P-210 FEASIBILITY OF THE CLAVIEN-DINDO CLASSIFICATION SYSTEM AFTER RADICAL OESOPHAGECTOMY C.S. Pramesh, S. Jiwnani, G. Karimundackal Thoracic Surgery and Surgical Oncology, Tata Memorial Centre, Mumbai, India Objectives: Oesophageal resections are associated with considerable morbidity and mortality. Complication rates vary widely with the variability primarily being due to differences in definitions and grading of postoperative complications. The Clavien-Dindo (CD) system of classifying postoperative complications is widely used in several specialties of surgery but large studies are lacking after radical oesophagectomy. We wanted to evaluate the feasibility of being able to classify all complicatons after oesophagectomy into one of the CD grades. Methods: We performed a prospective study between June 2011 and December 2014 to confirm the feasibility of documenting post oesophagectomy complications using the Clavien-Dindo system. A single observer documented and classified all in-hospital postoperative complications according to

the CD system. Grading was done for individual types of complications (pulmonary, anastomotic etc) with the highest complication grade considered as the aggregate complication grade for an individual patient. Complications with grade 3a and above were considered as major complications. Complications were expressed in the different grades as percentages of the total patients undergoing surgery for oesophageal cancer. Results: A total of 515 patients operated for oesophageal cancer between June 2011 and December 2014 were included in the study. The CD grading of postoperative complications were as follows: Grade 0, 225 (43.7%), Grade 1, 78 (15.1%), Grade 2, 21 (4.1%), Grade 3a, 107 (20.8%), Grade 3b, 30 (5.8%), Grade 4a, 21 (4.1%), Grade 4b, 1 (0.2%) and Grade 5, 32 (6.2%). 37.1% of patients had major complications. None of the complications were unclassifiable into the CD grades. Conclusions: The Clavien-Dindo system is feasible and offers an objective method of classifying complications after radical oesophagectomy. Standardized nomenclature or systems of classifying postoperative complications may enable comparisons across centres and studies. Disclosure: No significant relationships.
