Source abstract
The standard treatment for primary mediastinal yolk sac tumour involves neoadjuvant chemotherapy followed by residual tumour resection, typically performed through a median sternotomy or a thoracotomy. However, in this case, a 16-year-old patient with a large anterior mediastinal tumour underwent less invasive, subxiphoid, robot-assisted surgery using a 4-arm da Vinci Xi system with CO2 insufflation at 8 mmHg. The tumour, located in the right thymic lobe, was dissected using a technique similar to blunt dissection, bipolar electrocautery and vessel sealer. Pericardiotomy was performed suspecting tumour invasion, with the thickened pericardial border incised circularly from the left side. Preservation of the right phrenic nerve involved careful separation from the densely adherent tumour. A pulmonary wedge resection was also performed using a stapler. The pericardial defect was reconstructed using an expanded polytetrafluoroethylene sheet, sutured together with nylon threads, and the resected tumour was extracted with a retrieval bag. This subxiphoid robot-assisted approach is a minimally invasive option for malignant mediastinal tumours.
