ObjectiveTo explore the value of ultrasound-guided core needle biopsy (CNB) in diagnosis of thyroid nodules. MethodsThe clinical data of 347 patients with thyroid nodules who underwent ultrasoundguided CNB were retrospectively analyzed, and the results of CNB pathology were compared with postoperative wax pathology results. ResultsAll patients completed CNB successfully and satisfaction rate for tissue samples was 100%. After CNB, local hematoma occurred in two cases and relieved by conservative therapy. The CNB pathology results of 347 cases of patients were as follows: 117 cases were malignancy, including papillary thyroid cancer in 115 cases, undifferentiated adenocarcinoma in 1 case, and squamous cell carcinoma in 1 case; 230 cases were benign, including thyroiditis in 53 cases, and nodular goiter in 141 cases, adenoma in 16 cases, and nodular goitre coexisting thyroiditis in 20 cases. In 132 cases of patients underwent surgery including 113 cases of malignancy and 19 cases of benign disease, the CNB pathology results in 127 cases were consistent with postoperative wax pathology results and false negative occurred in 5 cases. The diameter of thyroid nodules were not more than 0.5 cm in 4 cases, 0.5-1.0 cm in 59 cases, 1-2 cm in 46 cases, and more than 2 cm in 23 cases, and the accuracy rate of CNB pathology results was 75.0%（3/4）, 98.3%（58/59）, 97.8%（45/46）, and 91.3%（21/23）, respectively, which was the highest in 0.5-2.0 cm. The accuracy, sensibility, specificity, positive predictive value, negative predictive value, failure rate, and misdiagnosis rate of ultrasound-guided CNB for differential diagnosis of thyroid malignant nodules from benign nodules were 96.21% (127/132), 95.76% (113/118), 100% (14/14), 1 (113/113), 0.74 (14/19), 4.24%(5/118), and 0 (0/14), respectively. ConclusionUltrasound-guided CNB has important value on differential diagnosis of thyroid nodules, and important guiding significance on treatment of thyroid diseases.
ObjectiveTo explore the consistency between core needle biopsy (CNB) by color ultrasound location and surgical biopsy in the diagnosis of breast diseases. MethodsBetween March 2012 and March 2015, the results of ultrasound-guided CNB pathological examination of 218 cases of breast diseases were retrospectively analyzed, which were compared with the results of postoperative histopathological diagnosis to evaluate the ultrasound-guided CNB diagnosis. ResultsIn the 218 cases, 156 of mammary cancer were confirmed by CNB histopathological diagnosis, and 160 were confirmed by the postoperative pathological histological diagnosis; the false negative diagnosis by CNB pathological diagnosis was 4. The two methods were highly matched with each other (k=0.958,P<0.001). The sensitivity of CNB histopathological diagnosis for mammary cancer was 97.5%, while the specificity was 100.0% and the accuracy rate was 98.2%. ConclusionCNB histopathologic diagnosis of breast lesions had high accuracy and high consistency with postoperative histopathological diagnosis results, which is a reliable biopsy method for breast lesions.
ObjectiveTo systematically review the diagnostic accuracy of C-arm cone-beam CT (CBCT)-guided percutaneous transthoracic needle biopsy (PTNB) for lung nodules. MethodsWe electronically searched databases including PubMed, EMbase, EBSCO, Ovid, CBM, VIP, WanFang Data and CNKI from inception to Feb 28th, 2015, to collect diagnostic studies of CBCT-guided PTNB for lung nodules. Two reviewers independently screened literature, extracted data and assessed the methodological quality of included studies by QUADAS-1 tool. Then, meta-analysis was performed by Stata 12.0 and Meta-DiSc 1.4 softwares for calculating pooled sensitivity (Sen), specificity (Spe), positive likelihood ration (+LR), negative likelihood ration (-LR), and diagnostic odds ratio (DOR), drawing summary receiver operating characteristic (SROC) curve and estimating area under the curve (AUC). ResultsA total of 9 studies involving 1 815 patients were included. The results of meta-analysis showed that the pooled Sen, Spe, +LR,-LR, and DOR were 0.95 (95%CI 0.92 to 0.96), 1.00 (95%CI 0.66 to 1.00), 2 076.58 (95%CI 1.8 to 2.3e+0.6), 0.05 (95%CI 0.04 to 0.08), and 39 443.88 (95%CI 30.53 to 5.1e+0.7), respectively. The AUC of SROC was 0.97 (95%CI 0.95 to 0.98). ConclusionCBCT-guided PTNB can be used as one of the primary examination approaches for lung nodules with relatively high diagnostic accuracy. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
Objective To discuss the nursing measures for thyroid nodule patients who undergo core-needle biopsy (CNB) guided by ultrasound. Methods We retrospectively analyzed the experiences and main points of nursing for 1 900 thyroid nodule patients who underwent CNB guided by ultrasound between June 2010 and May 2014. Results All the 1 900 patients underwent CNB successfully. The nursing time was between 5 and 15 minutes, averaging (8.0±3.7) minutes. Complications included hematoma in 25 patients (1.3%) and needle syncope reaction in 30 patients (1.6%), which were cured through symptomatic treatment. No complications such as nerve injury, anesthesia accident or death occurred. No medical disputes happened due to specimen errors or loss. The success rate of specimen collection was 98.4% (1 870/1 900), and the diagnostic accuracy was 95.3% (1 812/1 900). Conclusions Ultrasonography-guided CNB is a safe and reliable operation with a high success rate, high diagnosis accuracy and few complications. Being familiar with the process of nursing cooperation and correct disposal and transfer of biopsy specimens are crucial for successful CNB in patients with thyroid nodules.
Objective To investigate the clinical value and complication factors of percutaneous transthoracic needle biopsy (PTNB) guided by multislice computed tomography (MSCT). Methods From January 2013 to December 2016, 179 patients treated with MSCT-guided lung biopsy in the Affiliated Hospital of North Sichuan Medical College and Dianjiang People’s Hospital were reviewed. Occurrence rate and the influencing factors of complications were analyzed. Meanwhile, biopsy findings and diagnostic accuracy rate were summarized. Results A total of 129 cases of lung cancer were detected under MSCT-guided percutaneous biopsy in 179 patients with a diagnostic accuracy of 93.30%. The correct rate of malignant tumor diagnosis was 92.14%. The main complications were pneumothorax, pulmonary hemorrhage, dyspnea and hemoptysis. Major risk factors of MSCT-guided PTNB complications included lesion size ≤ 2 cm, the shortest distance to the diaphragm ≤ 5 cm, puncture depth > 5 cm, pleural puncture angle > 50°, the puncture times ≥ 2, puncture time ≥ 20 minutes, age of patients > 60 years, and existence of pulmonary disease (P<0.05). Conclusions The clinical application value of MSCT-guided PTNB is high. Skilled puncture technique and appropriate puncture procedure are helpful to reduce complications.
ObjectiveTo explore the application and effect of clinical nursing pathway based on information-knowledge-attitude-practice (IKPA) theory in percutaneous renal needle biopsy.MethodsThis is a historical control study. A total of 460 patients who underwent percutaneous renal biopsy in West China Hospital of Sichuan University between April and December 2020 were prospectively recruited as the pathway group, and a clinical nursing pathway based on IKAP theory was implemented. By contrast, the data of 617 patients who underwent percutaneous renal biopsy and received routine care in the same hospital between April and December 2019 were retrospectively collected as the control group. The length of hospital stay, hospitalization expenses, the incidences of postoperative complications (macroscopic haematuria, perirenal hematoma, and acute urinary retention), the incidence of postoperative postural hypotension, and the management enrollment rate of chronic kidney disease patients were compared between the two groups.ResultsThe length of hospital stay [median (lower quartile, upper quartile): 8 (7, 11) vs. 8 (7, 12) d] and the hospitalization expenses [median (lower quartile, upper quartile): 7380.50 (6401.86, 8789.21) vs. 8167.00 (6816.50, 10044.50) yuan] were less in the pathway group than those in the control group, the incidences of postoperative macroscopic haematuria (1.52% vs. 6.97%) and perirenal hematoma (2.61% vs. 5.02%) were lower in the pathway group than those in the control group, the management enrollment rate of chronic kidney disease patients was higher in the pathway group than that in the control group (26.09% vs. 6.16%), and the differences between the two groups were statistically significant (P<0.05). The differences in the incidences of acute urinary retention (8.26% vs. 11.18%) and postoperative postural hypotension (0.00% vs. 0.81%) between the two groups were not statistically significant (P>0.05).ConclusionThe application of clinical nursing pathway in percutaneous renal needle biopsy can effectively reduce the length of hospital stay and hospitalization expenses, and improve the management enrollment rate of chronic kidney disease patients.
ObjectiveTo compare the diagnostic accuracy, sampling satisfaction, and safety of ultrasound-guided core needle biopsy (CNB) and fine needle aspiration biopsy (FNA) for thyroid nodules.MethodsThe databases of PubMed, Medline, Web of Science, Cochrane Library, Wanfang, CNKI, and CBM were searched to collect the relevant studies on the diagnostic performance, sampling satisfaction, and safety of ultrasound-guided CNB and FNA for thyroid nodules. Revman 5.3 and Stata 15 software were used for meta-analysis.ResultsA total of 24 studies involving 25 388 patients were included. Meta analysis showed that: compared with CNB, FNA had poor diagnostic accuracy ［OR=0.26, 95%CI (0.15, 0.46), P<0.000 01］, poor sampling satisfaction ［OR=0.20, 95%CI (0.12, 0.33), P<0.000 01］, lower incidence of total complications ［OR=0.28, 95%CI (0.16, 0.50), P<0.000 1］, and lower incidence of bleeding after biopsy ［OR=0.62, 95%CI (0.48, 0.81), P=0.000 3］. However, there was no significant difference in the pain score ［WMD=–0.21, 95%CI (–0.57, 0.15), P=0.26］ between the two groups. Subgroup analysis showed that there was no significant difference in the accuracy of biopsy diagnosis of thyroid nodules with diameter less than 10 mm between the two groups ［OR=0.52, 95%CI (0.15, 1.81), P=0.30］, however, the accuracy of CNB in the diagnosis of thyroid nodules with diameter ≥ 10 mm was still better than FNA ［OR=0.26, 95%CI (0.12, 0.56), P=0.000 5］.ConclusionsCompared with FNA, ultrasound-guided CNB has a certain advantages in sampling satisfaction and the diagnosis accuracy of thyroid nodules with diameter ≥ 10 mm. CNB is better than FNA, but will bring higher risk of complication.
Objective To evaluate the diagnostic yield and safety of two biopsy methods, electromagnetic navigational bronchoscopy (ENB) and transthoracic needle biopsy (TTNB), in peripheral pulmonary lesions. To select a low-risk and high-benefit biopsy method based on the clinical characteristics of the lesions and patients. Methods A retrospective analysis was conducted on inpatients who underwent ENB and/or TTNB for peripheral pulmonary lesions in Huadong Hospital Affiliated to Fudan University. Propensity score matching was used to compare the diagnostic yield and safety of the two biopsy methods. Results A total of 126 patients were included in the ENB group, and 104 patients in the TTNB group. After propensity score matching, 83 matched pairs were obtained. The TTNB group exhibited a significantly higher diagnostic yield compared with the ENB group (90.4% vs. 48.2%, P<0.001), but it was also associated with a higher incidence of pneumothorax (1.2% vs. 21.7%, P<0.001). In the ENB group, the diagnostic efficacy was correlated with lesion diameter (P<0.001, OR=0.183, 95%CI 0.071 - 0.470), but there was no statistically significant difference in the diagnostic yield among different lung segments (P>0.05). In the TTNB group, lesion characteristics did not significantly affect the diagnostic yield, but a lesion diameter ≤30 mm (P=0.019, OR=5.359, 95%CI 1.320 - 21.753) and a distance from the pleura ≥20mm (P=0.030, OR=6.399, 95%CI 1.192 - 34.360) increased the risk of pneumothorax. When stratified based on lesion and patient blood characteristics, no significant difference was found in the diagnostic yield between the two groups for characteristics such as left upper lobe (P=0.195), right middle lobe (P=0.333), solid with cavity (P=0.567), or abnormal serum white blood cell count (P=0.077). However, the incidence of pneumothorax in the TTNB group was higher than that in the ENB group. Conclusions The diagnostic yield of ENB is affected by the size of the lesion, while the incidence of pneumothorax in TTNB is influenced by both lesion size and distance from the pleura. In cases with lesions located in the left upper lobe, right middle lobe, solid with cavity, or with abnormal serum white blood cell count, selecting ENB for biopsy is considered preferable to TTNB.
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.
