Abstract

Objective: To evaluate the surgical results of benign mediastinal teratomas at Viet Duc University Hospital in the period 2015 - 2021. Methods: A retrospective, cross-sectional descriptive study with all cases diagnosed as benign mediastinal teratomas operated at Viet Duc University Hospital from January 2015 to December 2021. Results: 46 patients, 15 men and 31 women. Mean age 28.98 ± 12.51. Chest pain was the most common symptom (80.43%). All tumors were located in the anterior mediastinum with an average tumor size of 8.4 ± 3.8 cm. There were 22 cases of sternotomy or thoracotomy (47.83%) and 24 cases of video-assisted thoracoscopic surgery (52.17%). All patients had complete resection, of which 08 patients (17.39%) had complete tumor resection with partial removal of surrounding tissue (pericardium, pleura, etc.) due to thickening. The average surgical time was 112.85 ± 40.44 minutes (50 – 210 minutes). The average postoperative drainage time was 5.25 ± 6.46 days, the postoperative hospital stay was 7.33±6.65days. Video-assisted thoracoscopic surgery had a shorter hospital stay than sternotomy and thoracotomy (p = 0.05). Conclusion: Patients with benign mediastinal teratoma have a good result after surgical treatment. During surgery it is necessary to pay attention to the problems of adhesion, bleeding and damage to adjacent organs. Video-assisted thoracoscopic surgery has been shown to be less painful, more esthetic, and has a short hospital stay in the indicated patient population.
