A Retrospective Study on Endoscopic Surgery for the Treatment of Paravertebral Abscess in Spinal Tuberculosis Patients
October 25th, 2024
This study evaluated endoscopic debridement for treating paravertebral abscesses in patients with spinal tuberculosis. Compared to conventional surgery, it significantly improved surgery time, blood loss, hospital stay, pain relief, and neurological outcomes, with fewer complications and no recurrences. These findings highlight its efficacy and safety. Further long-term studies are recommended.
We study the novel approach to treat spinal diseases, including but not limited to the degenerative spinal disorders, spinal trauma, spinal cord injury, spinal tumors, infections of the spine, including spinal tuberculosis. In the field of spinal tuberculosis treatment, the most recent advances are mainly the minimal invasive approach, especially endoscopic surgeries instead of open surgeries. The clinical study highlights the potential of endoscopic debridement as a safe and effective treatment modality for spinal tuberculosis. The technique not only effectively eliminates infected tissue, but also ensures faster patient recovery and reduces postoperative complications.
[Instructor] To begin position the patient prone on the operating table thoroughly disinfect the surgical area to maintain aseptic conditions and cover the patient with a sterile towel to ensure a sterile field around the surgical site. Using C-arm x-ray fluoroscopy accurately determine the exact point for the surgical incision. Then make a small incision at the determined point, ensuring minimal tissue disruption. To determine the surface projection of the lesion space, select the right sided foraminal level of the lesion as the needle puncture site. Angle the puncture needle at 20 to 35 degrees relative to the torso of the affected spine to facilitate soft tissue pathway expansion along the needle toward the spinal canal. After confirming the position fluoroscopically, make a five millimeter incision with a pointed scalpel and establish a subcutaneous tunnel through the incision. Next, thoroughly eradicate the paravertebral abscess to eliminate the primary source of infection. Then using nucleotomy forceps and biopsy forceps through the foraminal endoscope, remove purulent secretions and caseous necrotic tissue. After excising sequestrum, thoroughly clean the lesion. Collect tissue samples from the lesion for bacteriological culture, drug sensitivity testing, and pathological examination. Achieve complete relief of the front edge of the nerve and dermoid sack. The minimally invasive group had a significantly shorter operative time of about 74.3 minutes compared to 155.8 minutes in the conventional surgery group. The volume of intraoperative hemorrhage was significantly lower in the minimally invasive group compared to the conventional surgery group. The visual analog scale score significantly improved at three months and last follow-up in both groups with a lower score in the minimally invasive group. The Oswestry disability index significantly improved at three months and it last follow-up in both groups with better outcomes in the minimally invasive group compared to the conventional group.
