Abstract

Surgery for spinal metastases has undergone multiple transformations in terms of surgical technique. The need for a more aggressive surgical strategy for local control of the disease, given the advances in radiosurgery and immunotherapy, has met the incorporation of many different technological adjuncts. Separation surgery has become one of the main targets to achieve for surgeons in the treatment of spinal metastases. In this paper a prospective series of 3D endoscope-assisted transpedicular thoracic corpectomies is described. Adult patients with a diagnosis of single-level thoracic metastases requiring surgery for epidural compression were included. Data recorded for each case concerned patient demographics, surgical technique, clinical, radiological and surgical data, intra- and postoperative complications, follow-up. The goal of this study was to verify the achievement of separation surgery with this technique, while confirming the safety and feasibility of the procedure. A total number of nine patients were treated from January to April 2019 with a 3D endoscope-assisted procedure. A circumferential bilateral decompression was achieved in seven cases, while monolateral in the other two. A proper separation between the tumor and the spinal cord was achieved in all cases as confirmed by imaging. Axial pain always improved after the procedure as well as neurological functions, when compromised before surgery. No intra-operative and postoperative complications were recorded. Mean hospital stay was 4 days after surgery with early mobilization. At last follow-up no local recurrences were registered. According to preliminary results, the transpedicular 3D endoscope-assisted approach for corpectomies appeared to be a safe and effective technique to achieve proper circumferential decompression and valid separation surgery in thoracic metastases, potentially decreasing the need for costotransversectomy.
