Thoracic Eden IV dumbbell tumors are rare conditions characterized by neoplasms that arise from neurogenic elements, with intraforaminal and posterior mediastinal involvement. Surgical resection is commonly performed to treat thoracic Eden IV dumbbell-shaped tumors. The combined thoracic-neurosurgical approach is a routine surgical procedure according to the literature. We present our experience with resection of thoracic Eden IV dumbbell tumors with combined percutaneous spinal endoscopic and thoracoscopic procedures in a single stage. A retrospective review of 7 patients undergoing spinal endoscopic combined with thoracoscopic surgery for thoracic Eden IV dumbbell tumors was performed in our department between 2017 and 2020. Patient demographics, clinical features, operative reports, and preoperative and postoperative images were reviewed. Complete resection was achieved in the 7 cases. The mean operative time was 207 minutes (range, 160−310 minutes), with mean estimated blood loss of 47 mL (range, 20−80 mL). The mean chest drain duration was 3 days (range, 2−4 days), and the mean hospital stay was 7 days (range, 5−8 days). No operative complications were observed. During the follow-up period, there were no obvious complications, tumor recurrence, or spinal instability. Percutaneous spinal endoscopic combined with thoracoscopic surgery for the treatment of Eden IV type thoracic dumbbell tumors is a novel, safe, and effective surgical method that can not only remove tumors inside and outside of the thoracic intervertebral foramen in a single stage but also minimize damage to the normal structure of the spine and help in early recovery.
