Abstract:
Objective To investigate the value of intraoperative X-ray guided and CT guided percutaneous biopsy in the diagnosis of thoracic and lumbar space occupying lesions.Methods A total of 97 patients with thoracic and lumbar space occupying lesions who were not diagnosed clinically in our hospital from May 2011 to July 2016 were retrospectively analyzed.All patients underwent percutaneous vertebral biopsy under the guidance of Artis-Zeego robot in the Artis-Zeego complex operating room of our hospital.Thoracic vertebral body biopsy in patients with a total of 46 cases were divided into T group,in which X-ray guided percutaneous biopsy in 25 cases were divided into T-x group,CT guided percutaneous biopsy in 21 cases were divided into T-ct group.Lumbar puncture biopsy in patients with a total of 51 cases were divided into L group,in which X-ray guided percutaneous live review of 24 cases were divided into L-x group,CT guided percutaneous biopsy in 27 cases were divided into L-ct group.According to the packet respectively in X-ray or CT monitoring,the use of bone biopsy needle under local anesthesia,transpedicular approach for spinal lesions of bone amount,by changing the working path or direction bone biopsy needle of different diameter to save drilling samples which were immediately placed in 10％ formalin,specimens were sent for pathological examination and corresponding pathological and cytological examination.The success rate,diagnostic accuracy and complications of percutaneous biopsy were compared between the two groups in X-ray and CT guided percutaneous vertebral biopsy.Results T-x group of 25 patients,5 patients with puncture failure for intraoperative X-ray monitoring difficulties were transferred to puncture under the guidance of CT,the success rate of puncture was 80％ (20/25).Of the patients with success puncture,6 cases were unidentified by pathological examination,the total diagnostic accuracy rate of biopsy in T-x group was 70％ (14/20).The success rate of puncture in T-ct group was 100％,significantly higher than that of T-x group(P ＜ 0.05).In T-ct group,3 cases were unidentified by pathological examination,the total diagnostic accuracy rate of biopsy was 88.5 ％ (23/26),which was significantly higher than that of T-x group (P ＜ 0.05).In the L-x group,1 case with puncture failure for pain during the operation,the success rate of puncture was 95.8％ (23/24),patients of L-ct group were successfully punctured,the success rate was 100％,the difference between the two groups was not significant(P ＞ 0.05).In the L-x group,2 patients failed to confirm the diagnosis,the diagnostic total accuracy rate of L-x group was 87.5％ (21/23);of the L-ct group,1 cases failed to confirm the diagnosis,the diagnosis total accuracy rate of L-ct group was 96.3％ (26/27),the difference between two groups was not significant (P ＞ 0.05).Complications:In the T-x group,1 cases received additional local anesthetic after puncture for pain;1 patients had transient lower extremity paresthesia,and the symptoms were improved 1 weeks later;1 case with intraoperation puncture site paining was not alleviated and had to stop the puncture.All patients with CT guided biopsy had no complications.Conclusion CT and X-ray guided percutaneous biopsy has important significance in diagnosis and treatment of spinal lesions,and CT guided percutaneous biopsy is safer for thoracic lesions with higher diagnostic rate,while for lumbar lesions fluoroscopy,X-ray or CT guided percutaneous biopsy has the same security and diagnostic rate.
