ObjectiveTo evaluate the diagnostic value of BRAFV600E mutation test in high-risk thyroid nodules with easily underdiagnosed fine-needle aspiration biopsy (FNAB) results.MethodsRetrospectively collected 122 cases of thyroid nodule who treated in the Hebei Petrochina Central Hospital between January 2017 and December 2018, all the cases admitted preoperative ultrasound and FNAB detection. All of the patients had the non-positive cytological results of FNAB and the high-risk features of ultrasound. Contrasted the postoperative pathological coincidence rate of combination of FNAB and BRAFV600E test with FNAB alone.ResultsThe BRAFV600E mutation rate was 27.0% (33/122). The positive rate of BRAFV600E mutation increased with the increase of ultrasound thyroid imaging reporting and data system(TI-RADS) grade (P<0.05), which was independent of patients’ age, gender, number of nodules, diameter of nodules, and FNAB results (P>0.05). The coincidence rate of FNAB combined with BRAFV600E mutation detection was higher than that of FNAB alone ［86.9% (106/122) vs. 69.7% (85/122), P<0.05).ConclusionsThe BRAFV600E mutation test can detect papillary thyroid carcinoma that might be missed by FNAB. We recommend that FNAB should be routinely accompanied by the BRAFV600E mutation test in the high-risk thyroid nodules.
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 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 investigate the clinical features, chest imaging manifestations, pathological changes, diagnosis and treatment of sarcoidosis with pleural effusion as the initial manifestation, and to analyze the possible causes of misdiagnosis, so as to help clinicians improve their understanding of sarcoidosis with pleural effusion as the initial manifestation, and reduce the rate of clinical misdiagnosis and missed diagnosis. Methods The general data, clinical manifestations, imaging examinations, pathological findings and outcomes of 4 patients with sarcoidosis with pleural effusion as the first manifestation admitted to Ningxia Medical University General Hospital from January 2019 to December 2020 were retrospectively analyzed. Results Out of these patients, 3 were female and 1 was male, with an average age of 50.3 years. The main clinical features were cough, expectoration, chest tightness, shortness of breath and other common respiratory symptoms. Chest CT indicated right pleural effusion. After admission, closed thoracic drainage, tracheoscopy, thoracoscopy, pleural biopsy and cervical lymph node biopsy were performed to obtain pathology. Combined with imaging and pathology, diagnosis was made. After hormone therapy, symptoms and imaging were improved. Conclusions Sarcoidity-related pleural effusion is relatively rare as the first episode, with no specific clinical symptoms and no specific physical and chemical properties of pleural effusion. Non-caseous granulomatous lesions can be found pathologically, and the diagnosis needs to rely on clinical, imaging and pathological comprehensive judgment.
ObjectiveTo explore the clinical application of the comprehensive guidance technologies, such as cone beam computed tomography (CBCT), virtual bronchoscopic navigation (VBN), and superimposed high-frequency jet ventilator for respiratory control in the biopsy of peripheral pulmonary nodules (PPNs). MethodsThe clinical information of 3 patients with PPNs diagnosed by CBCT combined with VBN and superimposed high frequency superposition jet ventilator in Shanghai Changhai Hospital were retrospectively analyzed. Results Clinical data of 3 patients were collected. The average diameter of PPNs was (25.3±0.3) mm with various locations in left and right lung. The first nodule was located in the apex of the left upper lung, and the biopsy was benign without malignant cells. The lesion was not enlarged during the 5-year follow-up. The second one was located in the left lingual lung, and the postoperative pathology was confirmed as mucosa-associated lymphoma. The third one was located in the anterior segment of the right upper lung. After the failure of endobronchial procedure, percutaneous PPNs biopsy under CBCT combined with VBN was performed, and the pathological diagnosis was confirmed as primary lung adenocarcinoma. Postoperative pneumothorax complication occurred in the third patient with right lung compression rate approximately 20%. ConclusionsThe application of CBCT, combined with VBN and the superimposed high frequency jet ventilator for respiratory control can potentially improve the accuracy and safety in the diagnosis of PPNs. Multi-center clinical trials are needed to verify its further clinical application.
ObjectiveTo evaluate the difference between the tracheal intubation connected to conventional ventilation (TI-CV) and rigid bronchoscopy connected to high frequency ventilation (RB-HFV) under general anesthesia on patients with transbronchial cryobiopsy (TBCB).MethodA prospective, randomized, controlled trial was conducted in interstitial lung disease patients with TBCB from August 2018 to February 2019 in the First Affiliated Hospital of Guangzhou Medical University. According to the different methods of intubation, the patients were divided to a TI-CV group and a RB-HFV group randomly. The operating duration, extubation duration, total anesthesia time, heart rate, blood pressure and arterial blood gas analysis were collected and analyzed.ResultsSixty-five patients were enrolled. There were 33 patients with an average age of (48.0±15.0) years in TI-CV group and 32 patients with an average age of (48.8±10.8) years in RB-HFV group. The basic line of body mass index, pulmonary function (FEV1, FVC and DLCO), arterial blood gas (pH, PaO2 and PaCO2) and heart rate (HR), mean arterial pressure (MAP) had no significant differences between two groups. At the first 5 minutes of operation, the pH was (7.34±0.06) and (7.26±0.06), and the PaCO2 was (48.82±9.53) and (62.76±9.80) mm Hg in TI-CV group and RB-HFV group respectively, with significant differences (P=0.000). At the end of operation, the pH was (7.33±0.06) and (7.21±0.08), the PaCO2 was (48.91±10.49) and (70.93±14.83) mm Hg, the HR were (79.6±21.1) and (93.8±18.7) bpm, the MAP were (72.15±13.03) and (82.63±15.65) mm Hg in TI-CV group and RB-HFV group respectively, with significant differences (P<0.05). There were no differences in the operating duration and extubation duration between two groups. The total anesthesia time was (47.4±8.8) and (53.3±11.6) min with significant difference (P=0.017). Five minutes after the extubation, there were no significant difference in the pH, PaO2, PaCO2, HR and MAP between two groups. No serious complications occurred in either group.ConclusionsCompared with rigid bronchoscopy, TI-CV under general anesthesia is more conducive to maintain effective ventilation, and maintain the HR and MAP stable during the TBCB procedure. TBCB procedure should be performed by TI-CV under general anesthesia in patients with poor cardiopulmonary function.

MethodsLiteratures about the recent studies on categories of SLNB and the neck lymph node dissection conducted by SLNB in the surgery of thyroid carcinoma were reviewed following the results searched from PubMed and CNKI data base. ResultsSLNB has a high detection rate and it is of great significance to detect the occult metastatic lymph nodes and guide the neck lymph node dissection during operation. ConclusionThe SLNB, with its high accuracy rate on the detection of occult metastatic lymph nodes, guides neck lymph node dissection during operation in order that it can maximize the benefits of patients.
ObjectiveTo explore the incidence of and relative factors for infectious complications after transrectal prostatic biopsy. MethodsWe retrospectively analyzed the clinical data of 238 patients who underwent prostate puncture biopsy via rectum between January 2008 and December 2013, and analyzed the rate of infectious complications. At the same time, we compared the data of infection group and non-infection group to analyze the risk factors for infection. ResultsAmong the 238 patients, infectious complication was found in 25 cases (10.5%), and there was no significant difference between infection and non-infection group in age and pathological results (P>0.05). However, diabetes history and the increased number of puncture needles may increase the risk of infection (P<0.05). ConclusionThough transrectal prostatic biopsy is considered simple and safe, infectious complications may happen during the application. Reasonable evaluation, adequate preparation before biopsy and appropriate number of puncture needles are recommended to decrease the incidence of infections.
