Therapeutic effect of minimally invasive catheter drainage and local chemotherapy for the lumbosacral tuberculosis without neural symptoms

Increasing number of studies have shown growing incidence of lumbosacral tuberculosis and its complications. However, the treatment options for this disorder are still limited. To evaluate the long-term therapeutic effect and prognosis of minimally invasive puncture catheter drainage and Isoniazid local chemotherapy for the treatment of lumbosacral tuberculosis without neural symptoms under the guidance of computed tomography (CT). A total of 45 patients with asymptomatic lumbosacral tuberculosis were treated by minimally invasive catheter drainage under CT guidance. Forty-two cases had been followed up, which included 22 women and 20 men with an average age of 36.45 years old. Isoniazid was injected locally and antituberculotic drugs were administered for postoperative treatment. Oswestry Disability Index (ODI), visual analogue scale (VAS) evaluation and Cobb angle were recorded before and after operation. Forty-two patients had been followed up and the follow-up term was from 1.2 to 8.5 years (average 60 months). All patients were healed without recurrent cases. The ODI were improved from 14.86 ± 2.02 before operation to 1.48 ± 1.55 after operation. The post-operative (4.19 ± 1.17) VAS score was improved compared to the pre-operative VAS score (0.55 ± 0.55). The post-operative Cobb angle (6.19° ± 3.85°) was also improved relatively to the preoperative Cobb angle (5.90° ± 3.71°). Minimally invasive puncture catheter drainage combined with Isoniazid local chemotherapy is an effective method for lumbosacral tuberculosis without neural symptom. Meanwhile, it can be applied for the treatment of spinal tuberculosis before open surgery.
