Objective To systematically review the value of rapid on-site evaluation (ROSE) for diagnosing pulmonary and mediastinal lesions with endobronchial ultrasound (EBUS). MethodsPubMed, EMbase, The Cochrane Library, Web of Science, CNKI, Wanfang, and VIP databases were searched by computer to collect the studies of ROSE and EBUS in the diagnosis of pulmonary and mediastinal lesions from inception to August 2022. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies. Meta-analysis was implemented by RevMan 5.4 and Stata 12.0 software. ResultsA total of 15 studies (9 retrospective studies and 6 prospective studies) with 3 577 patients were included. The meta-analysis results of main outcomes showed that the adequacy of the sample (RD=0.10, 95%CI 0.05 to 0.15, P<0.000 1), overall diagnosis rate (RD=0.07, 95%CI 0.04 to 0.10, P<0.000 1) and the diagnosis rate of the malignant lesion (RD=0.06, 95%CI 0.02 to 0.09, P=0.004) of the ROSE combined with EBUS group were significantly higher than those of the EBUS group. Subgroup analysis showed that the diagnosis rates of pulmonary lesions (RD=0.12, 95%CI 0.08 to 0.17, P<0.000 01) and mediastinal lesions (RD=0.06, 95%CI 0.01 to 0.12, P=0.02) in the ROSE group was significantly higher than those in the EBUS group. The overall diagnosis rate and malignant diagnosis rate of ROSE combined with EBUS were 90% and 92%. The meta-analysis results of secondary outcomes showed that the number of lesions punctures (MD=–1.16, 95%CI –1.89 to –0.43, P=0.002) in the ROSE combined with EBUS group were significantly less than that in the EBUS group; there was no statistical difference in operation time (MD=0.09, 95%CI –5.22 to 5.39, P=0.97) or incidence of complications (RD=–0.06, 95%CI –0.13 to 0.01, P=0.1) between the two groups. Conclusion ROSE can improve the diagnostic efficiency of EBUS in pulmonary and mediastinal lesions, and has the value of the clinical application.
ObjectiveTo explore the risk factors of coronal imbalance after posterior long-level fixation and fusion for degenerative lumbar scoliosis.MethodsRetrospectivly analyzed the clinical records of 41 patients with degenerative lumbar scoliosis who had received posterior long-level fixation and fusion with selective transforaminal lumbar interbody fusion (TLIF) accompanied by Ponte osteotomy between August 2011 and July 2016. Patients were divided into imbalance group (group A, 11 cases) and balance group (group B, 30 cases) according to state of coronal imbalance measured at last follow-up. The radiographic parameters at preoperation and last follow-up were measured, and the variance of preoperative and last follow-up parameters were calculated. The radiographic parameters included coronal Cobb angle, coronal balance distance (CBD), apical vertebral translation (AVT), apical vertebral rotation (AVR), Cobb angle of lumbar sacral curve (LSC), and L5 tilt angle (L5TA). Univariate analysis was performed for the factors including gender, age, preoperative T value of bone mineral density, number of instrumented vertebra, upper and lower instrumented vertebra, segments of TLIF, decompression, and Ponte osteotomy, as well as the continuous variables of preoperative imaging parameters with significant difference were converted into two-category variables, obtained the influence factors of postoperative coronal imbalance. Multivariate logistic regression analysis was performed to verify the risk factors from the preliminary screened influence factors and the variance of imaging parameters with significant difference between the two groups.ResultsThe follow-up time of groups A and B was (3.76±1.02) years and (3.56±1.03) years respectively, there was no significant difference between the two groups (t=0.547, P=0.587). The coronal Cobb angle, AVT, LSC Cobb angle, and L5TA in group A were significantly higher than those in group B before operation (P<0.05), and all the imaging parameters in group A were significantly higher than those in group B at last follow-up (P<0.05). There was no significant difference between the two groups in parameters including the variance of coronal Cobb angle, AVT, and LSC Cobb angle before and after operation (P>0.05), and there were significant differences between the two groups in parameters including the variance of CBD, L5TA, and AVR (P<0.05). Univariate analysis showed that preoperative L5TA was the influencing factor of postoperative coronal imbalance (P<0.05). Multivariate logistic regression analysis showed that preoperative L5TA≥15° was an independent risk factor of postoperative coronal imbalance, and variance of pre- and post-operative AVR was a protective factor.ConclusionPreoperative L5TA≥15° is an independent risk factor for coronal imbalance in patients with degenerative lumbar scoliosis after posterior long-level fixation and fusion.
The precise anatomical division of liver segments is the foundation of liver surgery, while the anatomical division of the S9 segment of liver is a further precise division of the caudate lobe of the liver. This article retrospectively analyzed and summarized the precise minimally invasive ablation and follow-up results of four representative lesions of the S9 segment of liver, including primary liver cancer, recurrent liver cancer, metastatic liver cancer, and focal liver hyperplasia, treated at Affiliated Dongguan Hospital of Southern Medical University. The aim of this study is to explore the minimally invasive ablation effect of lesions located at the S9 segment of liver under CT guidance.
