RESUMO
BACKGROUND: Paravertebral abscess represents a prevalent manifestation of thoracic tuberculosis, often necessitating surgical intervention. In this study, we introduced a novel approach by employing bilateral endoscopic debridement (BED) to address large Paravertebral abscesses associated with thoracic tuberculosis, a method not previously proposed in the literature. The clinical efficacy was examined through a comprehensive 4-year follow-up. METHODS: We conducted a retrospective analysis on patients diagnosed with thoracic tuberculosis and paravertebral abscess who underwent BED combined with local antituberculosis drugs (BED + LAD) between February 2015 and February 2019. A total of 29 eligible patients (12 males and 17 females) with a median (interquartile ranges) of 59.0(16.5) years were included in the study. All patients received the BED + LAD treatment. After the surgery, the patients were treated with a 4-drug antituberculosis therapy (Rifampicin, Isoniazid, Pyrazinamide, and Ethambutol). All relevant indicators were meticulously recorded and analyzed. RESULTS: The surgical procedures were successfully completed for all subjects, with an average intraoperative bleeding volume of (25.2 ± 8.9) ml, an average surgical time of (68.4 ± 14.0) minutes, an average fluoroscopy frequency of (21.7 ± 8.2) times, an average hospital stay of (14.2 ± 4.3) days, and an average medication period of (42.1 ± 9.6) weeks. All subjects completed at least a 4-year follow-up period. At the final follow-up, ESR and CRP levels returned to normal, and there was no significant increase in the Cobb angle (P>0.05). CONCLUSIONS: The application of BED + LAD in the treatment of thoracic tuberculosis and paravertebral abscess proved to be a safe, effective, and feasible approach.
