Objective To evaluate the complication rate of CT-guided percutaneous lung biopsy and determine the risk factors. Methods A retrospective investigation of patients with CT-guided percutaneous lung biopsy in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine between2002 and 2009 was performed. The risk factors for complications were determined by multivariate analysis of variables related to patients’demographics, lung lesions, biopsy procedures, and individual radiological features. Results 281 biopsy procedures were enrolled. The total complication rate was 55. 9% with pneumothorax 32. 4% ( 91/281) , hemoptysis 34. 5% ( 97 /281) , and cutaneous emphysema2. 1% ( 6 /281) , and with no mortality.The pneumothorax rate was correlated with lesion location, lesion depth, and number of pleural passes. The bleeding risk was correlated with lesion size, lesion depth, and age. Prediction models for pneumothorax and bleeding were deduced by logistic regression. The pneumothorax model had a sensitivity of 80. 0% and a specificity of 62. 4% . And the bleeding model had a sensitivity of 67. 4% and a specificity of 88. 8% .Conclusions Lesion location, lesion depth, and number of pleural passes were independent risk factors for pneumothorax. Lesion size, lesion depth, and age were independent risk factors for bleeding. The prediction models for pneumothorax and bleeding will helpfully reduce the complication of CT-guided lung biopsy.
Objective To investigate the efficiency of manual reduction combined with uni-lateral percutaneous kyphoplasty (PKP) in treating osteoporotic vertebral compression fracture (OVCF). Methods Between May 2005 and May 2009, the manual reduction combined with uni-lateral PKP was appl ied to treat 42 patients with OVCF (group A), and the simple uni-lateral PKP was appl ied to treat 43 patients with OVCF (group B) at the same period. The visual analogue scale (VAS), the vertebral height, and the Cobb angle were determined before operation, and at 3 days and 6 months after operation. Ingroup A, there were 6 males and 36 females aged 59-93 years (76.5 years on average) with an average disease duration of 7 days (range, 3 hours to 21 days); 27 segments of thoracic vertebrae and 31 segments of lumbar vertebrae were involved, including 15 segments at mild degree, 38 segments at moderate degree, and 5 segments at severe degree according to degree classification system of compression fractures of Zoarski and Peh. In group B, there were 9 males and 34 females aged 54-82 years (75.3 years on average) with an average disease duration of 7 days (range, 1 hour to 20 days); 26 segments of thoracic vertebrae and 35 segments of lumbar vertebrae were involved, including 21 segments at mild degree, 36 segments at moderate degree, and 4 segments at severe degree according to degree classification system of compression fractures of Zoarski and Peh. There were no significant difference (P gt; 0.05) in sex, age, affected site, degree, and disease duration between 2 groups. Results There was no significant difference (P gt; 0.05) in operative time, blood loss, or injected cement volume between 2 groups. No serious compl ication or death occurred in 2 groups. Cement leakage was observed in 4 cases (9.5%) of group A and in 5 cases (11.6%) of group B. The VAS scores after operation significantly decreased in 2 groups (P lt; 0.01). At 3 days and 6 months after operation, the VAS scores in group A were significantly lower than those in group B (P lt; 0.05). The postoperative compression rates of affected vertebral body in 2 groups significantly decreased (P lt; 0.01). The compression rates of affected vertebral body at 3 days and 6 months after operation, and the height recovery rate at 3 days after operation in group A were superior to those in groupB (P lt; 0.05). The postoperative Cobb angles in 2 groups were significantly diminished (P lt; 0.01). The Cobb angles at 3 days and 6 months after operation, and the recovery rate at 3 days after operation in group A were superior to those in group B (P lt; 0.05). Conclusion The cl inical efficiency of the manual reduction combined with uni-lateral PKP is superior to that of simple uni-lateral PKP in treatment of severe OVCF.
ObjectiveTo compare the effectiveness and safety of electromagnetic navigation-guided localization and CT-guided percutaneous localization for pulmonary nodules.MethodsThe literature published from the inception to January 2021 about the comparison between electromagnetic navigation-guided localization and CT-guided percutaneous localization for pulmonary nodules in the PubMed, The Cochrane Library, Web of Science, EMbase, Chinese Wanfang database and CNKI database was searched. RevMan (version 5.4) software was used for meta-analysis. Nonrandomized controlled trials were evaluated using methodological index for nonrandomized studies (MINORS).ResultsA total of six retrospective studies (567 patients) were included in this meta-analysis. MINORS scores of all studies were all 17 points and above. There were 317 patients in the CT-guided percutaneous localization group and 250 patients in the electromagnetic navigation-guided localization group. The complication rate of the CT-guided percutaneous localization group was significantly higher than that in the electromagnetic navigation-guided localization group (OR=11.08, 95%CI 3.35 to 36.65, P<0.001). There was no significant difference in the success rate of localization (OR=0.48, 95%CI 0.16 to 1.48, P=0.20), localization time (MD=0.30, 95%CI –6.16 to 6.77, P=0.93) or nodule diameter (MD=–0.07, 95%CI –0.19 to 0.06, P=0.29) between the two groups.ConclusionElectromagnetic navigation can be used as an effective preoperative positioning method for pulmonary nodules, which has the advantage of lower complication rate compared with the traditional CT positioning method.
ObjectiveTo systematically review the value of the fine-needle biopsies in the diagnosis of benign and malignant breast nodules. MethodsA computer based online search was conducted in PubMed, The Cochrane Library (Issue 7, 2016), EMbase, CBM, CNKI, VIP, WanFang Data databases up to August, 2016 to collect the relevant diagnostic studies of the fine-needle biopsies for benign and malignant breast nodules. Two reviewers independently screened literature, extracted data and assessed the methodological quality of included studies. Then, meta-analysis was performed using Stata 12.0 and Meta-Disc 1.4 software.ResultsA total of 22 studies involving 24 496 patients were finally included. The results of meta-analysis showed that the pooled Sen, Spe, +LR, –LR, and DOR were 0.95 (95%CI 0.95 to 0.96), 0.96 (95%CI 0.96 to 0.96), 38.27 (95%CI 23.17 to 63.19), 0.05 (95%CI 0.03 to 0.07), 1 031.11 (95%CI 514.19 to 2 067.68), respectively. The AUC of SROC was 0.99 (95%CI 0.98 to 1.00).ConclusionThe current evidence indicates that the FNAC has high diagnostic value in the differential diagnosis of benign and malignant breast nodules.
Objective To evaluate the effect of ultrasound guided percutaneous drainage on acute perforation of gastroduodenal ulcer in elderly patients. Methods The clinical features, treatments, and the curative effects of 86 elderly cases (≥65 years) of acute perforation of gastroduodenal ulcer in our hospital between January 2004 and October 2009 were retrospectively analyzed. Twenty-one cases were treated by ultrasound guided percutaneous drainage (drainage group), and 65 cases were treated by exploring operation (operation group). Results Drainage group was cured and had no complications. In 15 patients which accepted recheck one month after drainage, gastroscope showed the ulcer healed in 12 cases， and improved in 3 cases. In operation group, 63 cases were cured and 2 cases died. Compared with the drainage group, there was no significant difference in cure rate (Pgt;0.05). However, 11 patients had operative complications in operation group, which was significantly more than that in the drainage group （Plt;0.05）. In 45 patients which accepted recheck one month after operation, gastroscope showed the ulcer healed in 38 cases， and improved in 7 cases. Conclusion For elderly patients with acute perforation of gastroduodenal ulcer， if the patients do not fit for exploring operation， ultrasound guided percutaneous drainage is proved to be a simple, safe, and effective means.
