Pure uniportal video-assisted thoracic surgery for treating thoracic tuberculous spondylitis: an initial case series of seven patients.

Background: The development of thoracic surgical techniques has provided a new avenue for treating thoracic tuberculosis. Moreover, microscopic treatment of spinal tuberculosis has attracted increasing attention, as it affords good visual access and reduces trauma. Traditional thoracoscopic treatment of spinal tuberculosis usually requires 2-3 passages, accompanied by a corresponding number of incisions. With a large number of conventional thoracoscopic surgeries performed, improved resolution of the microscopic field of view, effective hemostasis of the peripheral vessels using the ultrasonic knife, and many reports in the literature, thoracic tuberculosis can now be treated microscopically by creating a single channel. The aim of this study was to explore the feasibility and surgical technique for thoracic tuberculous spondylitis treatment via debridement and bone graft fusion surgery employing pure uniportal video-assisted thoracic surgery (VATS), combined with posterior internal fixation.

Methods: Seven patients with relatively complete documentation were included in this study. All patients underwent lesion removal and bone graft reconstruction via uniportal VATS with posterior internal fixation. The mean patient age was 39.6 years. Surgical duration, blood loss volume, postoperative recovery time, and thoracic kyphosis angle were recorded.

Results: The surgeries were successful with no severe postoperative complications. All patients were followed-up, and no recurrence of tuberculosis was observed. Imaging data, including computed tomography scans, confirmed the complete removal of the lesions. Additionally, bone fusion at the graft site was successful, no loss of the thoracic kyphosis angle was noted postoperatively, and the thoracic kyphosis angle improved.

Conclusions: Pure uniportal VATS yields satisfactory results and inflicts less trauma than previous surgical techniques. This technique also offers a reference value for treating thoracic tuberculous spondylitis.
