Objective:To investigate the application value of CT-guided localization with medical glue or puncture needle before thoracoscopic pulmonary ground-glass nodule resection.Methods:The clinical data of 92 patients who underwent localization before thoracoscopic resection of pulmonary ground-glass nodules in Beijing Chao-Yang Hospital from June 2019 to November 2022 were retrospectively analyzed. According to the preoperative localization method, the patients were divided into puncture needle group (52 cases) and medical glue group (40 cases). The localization success rate, localization time and incidence rate of complications were compared between the two groups.Results:The success rate of localization in both groups was 100%. In puncture needle group, the guide wire of 1 case (1.9%) prolapsed, but it did not affect the surgical resection. The localization time of puncture needle group and medical glue group was (18±6) min and(14±5) min, and there was a statistical difference between the two groups ( t = 3.06, P = 0.003). The incidence of bleeding and pneumothorax in medical glue group was lower than that in puncture needle group [12.5% (5/40) vs. 38.5% (20/52), χ2 = 7.70, P = 0.009; 35.0% (14/40) vs. 71.2% (37/52), χ2 = 11.96, P = 0.001]. The incidence rate of irritating cough in was higher than that in puncture needle group [50.0% (20/40) vs. 11.5% (6/52), χ2 = 16.50, P < 0.05]. Conclusions:CT-guided localization with medical glue or puncture needle can achieve satisfactory results in the localization of pulmonary ground-glass nodule before thoracoscopic resection and help to improve the accuracy of surgical resection. The incidence rates of bleeding and pneumothorax of medical glue localization are lower than those of puncture needle localization.

Objective:To compare postural reduction combined with percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fractures (OVCFs).Methods:From January 2019 to January 2020,68 patients with OVCFs who met the inclusion and exclusion criteria in the Second Hospital of Tangshan Hebei Province were included in the observation study. A prospective randomized controlled study was used. The matched groups were divided into PVP combined group (adjust the overextension of the operating table by 20°-30°, if the posture reduction fails, pry the puncture needle on both sides in reverse according to the compression degree of the end plate before operation, and inject bone cement) and PKP group (do not adjust the operating table before operation, insert a balloon and expand on both sides after operation, and inject bone cement), with 34 cases in each group. The Cobb angle of the injured vertebrae was measured by taking the anterior and lateral X-ray film of the patient's lumbar spine before operation. The degree of pain and low back function were evaluated by visual analogue scale (VAS) and Oswetry disability index (ODI). The operation time and fluoroscopy times were recorded during the operation. On the second day after operation, the anterior and lateral X-ray of lumbar spine were taken to measure the Cobb angle of injured vertebrae. All patients were underwent computed tomography (CT) check the bone cement for leakage, record the VAS score, and record the ODI 3 months after operation to evaluate the patient's function. Follow up at the end of 12 months after operation to count the treatment cost and re-fracture of the patient. The data analysis and measurement data were compared by independent sample t-test between the two groups, paired sample t-test was used for intra-group comparison before and after operation. χ 2 test was used for counting data comparison between two groups. Results:All patients were followed up for 12 months. The operation time ((42.7±5.9) min), fluoroscopy times ((20.0±3.6) times) and treatment cost ((19 153±601) yuan) in the PVP combined group were better than those in the PKP Group ((67.4±7.3) min, (30.1±5.9) times, (27 496±669) yuan), and the difference was statistically significant ( t values were 15.39, 8.46, 54.12; all P<0.001). Cobb angle: Postoperative Cobb angle of injured vertebrae in the two groups (PVP combined group (10.7±4.5)°) and (PKP group (13.4±3.8)°) decreased compared with preoperative (PVP combined group (17.0±5.1)°) and (PKP group (16.7±5.1)°) ( t values were 10.61, 5.61; all P=0.001), and PVP combined group recovered better than PKP group, with statistically significant difference ( t=2.70, P=0.009). VAS score: Postoperative (PVP combined group (3.9±1.5) points) and (PKP group (4.1±1.6) points) was lower than preoperative the scores of (PVP combined group (6.9±1.1) points) and (PKP group (7.1±0.9) points), and the difference was statistically significant ( t values were 8.63, 8.88; all P=0.001). There was no significant difference in VAS scores between the two groups ( t=0.48, P=0.630). ODI scores: The scores of (PVP combined group (0.315±0.068)) and (PKP group (0.319±0.077)) after operation were lower than preoperative (PVP combined group (0.574±0.066), (PKP group (0.553±0.075)), and the difference was statistically significant ( t values were 18.54, 14.16, all P=0.001). There was no significant difference in ODI between the two groups ( t=0.25, P=0.803). There was no statistical significance in the two groups of postoperative bone cement leakage (χ 2=0.22, P=0.642). In PVP combined group, 1 case was re-fractured due to trauma, and there was no re-fracture in PKP group. Conclusion:Postural reduction combined with percutaneous needle prying reduction of PVP and PKP can alleviate the pain, improve the postoperative function and restore kyphosis in patients with OVCFs. Postural reduction combined with needle prying reduction of PVP has more advantages in operation time, radiation injury to doctors and patients, treatment cost, and the effect of correcting deformity is more significant.
