Total en bloc spondylectomy for vertebral tumors
Background:
Most spine tumors are resistant to radiation and chemotherapy. Complete surgical removal provides the best chance for long-term control of the tumor. Total en bloc spondylectomy (TES) is a radical new technique that entails total removal of the tumor and affected vertebras with clean margins.
Objectives:
To review our initial experience with TES, focusing on feasibility, surgical challenges and the short-term outcome.
Methods:
We retrospectively reviewed the hospitalization charts and follow-up data of all patients treated with TES for spine tumors in the spine unit at Tel Aviv Medical Center.
Results:
TES was performed in 12 patients aged 13-78 years. Nine patients had primary spinal tumors and three had metastasis. Total en bloc removal was achieved in all cases with spondylectomy of one to three affected vertebras. There was no perioperative mortality and only one major intraoperative complication of injury to a major blood vessel. Late complications were mainly related to hardware failure.
Conclusions:
Total en bloc spondylectomy is feasible and effective for the management of selected patients with extradural spinal tumors. Since the surgical procedure is demanding and carries significant risk, careful preoperative evaluation and collaboration with colleagues from other specialties are crucial.
