Background: Video-assisted thoracic surgery (VATS) has been increasingly used for the diagnosis and treatment of thoracic diseases. Pediatric mediastinal tumors are often difficult to resect because of their proximity to important organs. For this reason, VATS is not established as a standard surgical approach for such tumors. We compared the efficacy and safety of mediastinal tumor resection in children using open thoracotomy (OT) and VATS.
Methods: A total of 31 children underwent mediastinal tumor resection (21 by VATS and 10 by OT). These nonrandomized approaches were retrospectively compared for incidence of operative complications, morbidity, and mortality.
Results: Tumor sizes and operation times were similar between groups. However, the VATS group required significantly fewer blood transfusions and shorter durations of thoracic drainage and hospital stays (p<0.05). Complications greater than grade 2 on the Clavien-Dindo classification occurred in four patients treated by VATS and OT. No delayed effects were noted in the survivors of either group. A patient with clear cell sarcoma of the kidney who underwent OT relapsed and died.
Conclusion: Although complication rates were similar between the two approaches, VATS was suggested as less invasive because of fewer blood transfusions required, and shorter thoracic drainage and hospital stay durations.
