RESUMO
INTRODUCTION: Tumors of the mediastinum are a heterogeneous group of dysembryoplatic and neoplastic diseases essentially with different prognoses and therapeutic. These tumors develop slowly and remain long asymptomatic in 40-50% of cases. The purpose of our work is to bring the result of surgical management in diagnostic and therapeutic of principal mediastinum tumors framework. PATIENTS AND METHOD: We reviewed retrospectively the records of 68 patients in our training, between January 2009 and December 2013, for tumor of the mediastinum in the diagnostic framework and or therapy. RESULTS: There were 37 men and 31 women with a mean age of 37 years with extremes ranging from 11 to 73 years and 77.94% had an age between 11 and 50. In 39 patients, surgery had a diagnostic purpose (2 benign tumors and 37 malignancies including 27 cases of lymphomas). Curative surgery was performed in 34 patients, dominated by the tumors of thymic origin in 15 cases. Conventional surgery had involved 32 patients. The surgical approach was a total vertical sternotomy in 14 patients, in 17 patients was posterolateral thoracotomy and a left anterior thoracotomy in 1 patient. Video assisted thoracic surgery had been done in 3 patients under resection of a pleuropericardique cyst. Overall mortality was 4.41 percent. It is a death at D17 of the postoperative (thymoma with myasthenia) following a myasthenic crisis requiring a tracheotomy. A patient operated on for invasive thymoma developed myopathy and died at D44 of the postoperative following a difficulty of weaning. Another patient had a thymoma B3 benefited from 6 courses of neoadjuvant chemotherapy and then a thymectomy had presented a respiratory distress with bilateral pleural effusion, death at D10 of the postoperative by septic shock following a nosocomial infection. CONCLUSION: Tumors of the mediastinum are infrequent, discovered more often by chance. The main prognostic factor is the completeness of tumor resection without taking the break. Conventional surgery always keeps a place in our context, despite the advent of minimally invasive surgery.
