Aim

In this study, we aimed to evaluate the results of our patients with a primary mediastinal mass and the surgical techniques applied in our clinic retrospectively.

Material and methods

Between March 2015 and March 2019, the results and treatment protocols of 32 patients with a primary mediastinal mass or cysts who were followed up and treated in our clinic were evaluated retrospectively. Twenty-six patients who underwent surgery for biopsy or resection were included in the study.

Results

Sixteen of our patients were male and 10 were female. The mean age was 39 years. 80.2% of our patients were symptomatic and 19.2% were asymptomatic and a mediastinal mass was incidentally detected in these asymptomatic patients. The most common symptom was dyspnea with frequency of 38.4%. In terms of localization, the mass was lateralized on the right side in 7 patients, on the left side in 5 patients. In 13 patients, the tumor was located in the posterior mediastinum. 8 patients underwent anterior mediastinotomy and 1 patient underwent biopsy with video-assisted thoracoscopic surgery (VATS). Most commonly a thymus-derived mass was seen. Fifteen patients underwent excision with VATS, 3 thoracotomy, 2 sternotomy and in 1 patient VATS assisted anterior minithoracotomy was performed.

Conclusions

Mediastinal tumors and cysts have different histopathological features. Robotic surgery and VATS-assisted surgery are increasingly used in surgical excision.
