Summary

For giant mediastinal teratomas, the only treatment option available is usually open-chest surgery, which causes significant trauma, leads to obvious postoperative pain and may result in long-term complications such as chest wall deformity. Currently, we have developed a new treatment method. We use a double retractor system to pull the upper and lower ends of the sternum, lifting it to obtain sufficient surgical space behind the sternum. This enables us to perform minimally invasive tumor resection through the subxiphoid approach with thoracoscopy. The advantages of this method include reduced surgical trauma and postoperative pain, shortened hospital stay, and improved cosmetic effect

PROCEDURE

Subxiphoid Minimally Invasive Resection of Giant Mediastinal Teratoma Assisted by Double Sternal Elevation

All patients underwent minimally invasive mediastinal tumor resection using a double hook technique via the subxiphoid approach. The procedure was as follows: A 3-4 cm longitudinal incision was made below the xiphoid, and subcutaneous tissue was dissected to reach the anterior rectus sheath. The retroxiphoid space was bluntly dissected, and a thoracoscopic lens was inserted. A double-retractor system was placed in the subxiphoid and suprasternal regions, and retractor height was adjusted to aid in separating tumor adhesions from residual thymic tissue. Blunt dissection was used to separate the tumor from the innominate vein and phrenic nerve. After full tumor mobilization, it was placed into a sterile specimen bag and removed through the incision. The surgical area was rinsed and a mediastinal drainage tube was inserted, and the incision was closed layer by layer.
