Purpose There are few articles in the literature comparing outcomes between anterior and posterior instrumentation in the management of thoracic and lumbar spinal tuberculosis (TB). Methods Between January 2004 and December 2009, 217 adult patients, average age 39 (range 16-67) years with thoracic and lumbar spinal TB were treated by anterior radical debridement and fusion plus instrumentation, anterior radical debridement with fusion and posterior fusion with instrumentation, posterolateral debridement and fusion plus posterior instrumentation or transpedicular debridement and posterior fusion with instrumentation in a single-or two-stage procedure. We followed up 165 patients for 22-72 (mean 37) months. Of these, 138 underwent more than three weeks chemotherapy with isoniazid, rifampin, pyrazinamide and ethambutol, and the remaining 27 underwent operation for neurological impairment within six to 18 hours of the same chemotherapy regimen. In no case did relapse occur. Apart from eight patients with skip lesions treated by hybrid anterior and posterior instrumentation, anterior instrumentation was used in 74 patients (group A) and 83 patients (group B) were fixed posteriorly. Results In both groups, local symptoms were relieved significantly one to three weeks postoperatively; ten of 14 patients (71%) in group A and 14 of 19 (74%) in group B with neurological deficit had excellent or good clinical results (P>0.05). Erythrocyte sedimentation rates (ESR) returned from 43.6 mm/h and 42.7 mm/h, respectively, preoperatively to normal levels eight to 12 weeks postoperatively. Kyphosis degree was corrected by a mean of 11.5°in group A and 12.6°in group B, respectively (P< 0.01). Correction loss was 6.8°in group A and 6.1°in group B at the last follow-up (P<0.01). Fusion rates of the grafting bone were 92.5% and 91.8%, respectively, at final follow-up (P>0.05). Severe complications did not occur. Conclusion These results suggest that both anterior and posterior instrumentation attain good results for correction of the deformity and maintaining correction, foci clearance, spinal-cord decompression and pain relief in the treatment of thoracic and lumbar spinal TB providing that the opeartive indication is accurately identified. However, the posterior approach may be superior to anterior instrumentation to correct deformity and maintain that correction.
Posterior instrumentation was more effective than anterior instrumentation in the correction of kyphosis and the maintenance of the correction. However, postoperative sinus formation was more frequent in patients who underwent a single-stage posterior procedure.
Objective: To investigate surgical methods and outcomes in the treatment of spinal tuberculosis (TB) in adults. Subjects and Methods: One hundred and eighty-one patients (average age 39 years) without multiple-level noncontiguous spinal TB were followed up for 22-72 months. The patients were divided into four groups according to surgical procedure on the basis of the position and extension of the foci: group A (74 cases): anterior radical debridement and strut grafting with instrumentation; group B (83 cases): posterior instrumentation and bone grafting with anterior radical debridement and strut grafting in a single- or two-stage procedure; group C (10 cases): extrapleural anterolateral decompression and strut grafting with posterior instrumentation in thoracic or thoracolumbar spine, and group D (27 cases): single-stage transforaminal decompression and posterior instrumentation and fusion. Results: There was a significant decrease (p < 0.05) in mean preoperative (81%) Oswestry's Disability Index. Except for 24 patients with lumbosacral TB who were only instrumented posteriorly, kyphosis degrees were corrected by a mean of 11.5° in the anterior instrumentation group and 12.6° in the posterior instrumentation group (p < 0.01). The correction loss was 6.8° in the anterior instrumentation group and 6.1° in the posterior instrumentation group at the last follow-up (p < 0.01). Conclusion: The four surgical procedures obtained good results for correction and maintenance of the correction, clearance of the foci, decompression of the spinal cord and pain relief in the treatment of spinal TB in adults, providing that the operative indication is accurately identified. However, the posterior approach was superior to anterior instrumentation for correcting deformity and maintaining the correction.
A chitosan-coated pressed calcium sulfate pellet combined with recombinant human bone morphogenetic protein 2 (rhBMP-2) has been developed with increased compressive strength and osteoinduction, but with a resorption profile only slightly slower than uncoated pellet. A radial segmental defect model of rabbit was used to study the restoration effect on defect treated with chitosan-coated pressed calcium sulfate pellet combined with rhBMP-2, coated pressed calcium sulfate pellet, and uncoated pressed calcium sulfate pellet. Nothing was implanted in the control group. After 4, 8, and 12 weeks, the results indicated that coated pressed calcium sulfate pellet combined with rhBMP-2 and coated pressed calcium sulfate pellet facilitated new bone formation on defected bone and that particularly the former was more effective than the latter.
Purpose
The purpose of this study was to investigate the effectiveness and safety of the operation for type III esophageal atresia using a thoracoscope.
Methods
The clinical data for 92 patients with type III esophageal atresia in our hospital from January 2015 to December 2018 were analyzed retrospectively. There were 49 patients in group A who underwent thoracoscopic surgery and 43 patients in group B who underwent conventional surgery.
Results
The mechanical ventilation time (55.7 ± 11.4 h vs 75.6 ± 19.2 h), intensive care time (3.6 ± 1.8d vs 4.7 ± 2.0d), postoperative hospitalization time (13.1 ± 2.2d vs 16.8 ± 4.3d), thoracic drainage volume (62.7 ± 25.5 ml vs 125.4 ± 46.1 ml), blood transfusion volume (30.5 ± 10.4 ml vs 55.3 ± 22.7 ml) and surgical incision length (2.0 ± 0.5 cm vs 8.0 ± 1.8 cm) in group A were lower than those in group B, and the differences were statistically significant (P < 0.05). Among the postoperative complications, the incidences of postoperative severe pneumonia (8.2% vs 23.3%), poor wound healing (2.0% vs 14.0%) and chest wall deformity (0% vs 11.6%) in group A were significantly lower than those in group B (P < 0.05). There was no significant difference in the incidence of anastomotic stricture, tracheomalacia or gastroesophageal reflux between the two groups after surgery and early during follow-up (P > 0.05), and there were no complications such as achalasia signs and esophageal diverticulum in either group.
Conclusion
Surgery for type III esophageal atresia via thoracoscopy has the same safety and clinical effectiveness as traditional surgery and has the advantages of smaller incision and chest wall deformity.
