Acute respiratory distress syndrome is a clinical syndrome caused by many reasons, which is characterized by intractable hypoxemia. Its etiology is complex and its mortality is high. Lung biopsy techniques can give accurate histopathological diagnosis to such patients to guide treatment and improve prognosis. At present, lung biopsy techniques include surgical lung biopsy, transbronchial lung cryobiopsy, transbronchial lung biopsy and percutaneous lung biopsy. The diagnostic rate of surgical lung biopsy is high, but it is traumatic and difficult to implement. The diagnostic rate of transbronchial cryobiopsy is relatively high, and the complications are acceptable. Transbronchial lung biopsy is minimally invasive but the diagnostic rate is low. The diagnostic rate of percutaneous lung biopsy is relatively high, and the complications are relatively few. For patients with acute respiratory distress syndrome who need lung biopsy, it is very important to choose different surgical procedures according to their effectiveness, safety and applicability.
Objective To evaluate the application value of spiral CT virtual endoscopy and three dimensional imaging in fiberoptic bronchoscopic balloon dilation in patients with benign tracheobronchial stenosis. Methods Thirty-three cases of benign tracheobronchial stenosis from June 2004 to November 2008 were checked by spiral CT with airway tracheobronchial reconstruction. For the patients with indications, balloon dilatation was performed under fiberoptic bronchoscope. The three-dimensional reconstruction images were compared with the findings under bronchoscopy. And the preoperative and postoperative three-dimensional reconstruction images were compared for airway diameter. Results Three cases were found stenosis of middle lobe by CT virtual endoscopy and did not undergo balloon dilatation. The remaining 30 cases were confirmed by bronchoscopy findings similar to the images by tracheobronchial reconstruction with CT, with consistent rate of 100% . Immediate postoperative three-dimensional CTreconstruction of tracheal bronchus revealed that diameter of stenotic bronchus increased from ( 2. 7 ±1. 3) mm to ( 6. 9 ±1. 6) mmafter operation. Conclusion Multislice spiral CT virtual endoscopy is helpful in fiberoptic bronchoscopic balloon dilation in patients with benign tracheobronchial stenosis and postoperative follow-up.
ObjectiveTo explore the efficacy of community-acquired pneumonia (CAP) by tracheoscopy intervention altimeter and analyze and compare its financial burden.MethodsRetrospective analysis of 419 hospitalized patients with CAP was carried in respiratory medicine department of four hospitals from July 1, 2017 to August 31, 2018 (Changhai Hospital, Shanghai First People’s Hospital, Baoshan Branch of Shanghai First People’s Hospital, and Baoshan Integrated Traditional Chinese and Western Medicine Hospital). According to the time of tracheoscopy intervention treatment, they were divided into 3 groups: 127 patients treated with tracheoscopy intervention during the initial treatment period (within 72 h after obtaining imaging diagnosis) were included in an early intervention group, 158 patients treated with tracheoscopy intervention 72 h after obtaining imaging diagnosis were included in a medium-term intervention group, and 134 patients treated without tracheoscopy intervention were included in a non-intervention group. The total efficiency of treatment, improvement of clinical symptoms, imaging absorption, serum inflammation index level, sputum culture positive rate, change rate, efficiency after drug change, hospital stay and hospitalization cost were compared among three groups.ResultsThe total efficiency of treatment in the early intervention group was higher than that of the medium-term intervention group and the non-intervention group, with statistically significant difference (P<0.05), and the time of normality of body temperature, the time of disappearance of strong sputum and cough in the early intervention group, the absorption time of chest X-rays were shorter than that of the medium-term intervention group and the non-intervention group, and the difference was statistically significant (P<0.05); peripheral blood hemoglobin, serum calcitonin and hypersensitive C reactive protein levels were lower than those in the medium-term intervention group and the non-intervention group, with statistically significant differences (P<0.05), and the sputum-positive and drug-change rates in the early intervention group and the medium-term intervention group were higher than those in the non-intervention group, and the difference was statistically significant (P<0.05); the duration of hospital stay in the early intervention group was shorter than that of the medium-term intervention group and the non-intervention group, and the cost of hospitalization was less than that of the medium-term intervention group and the non-intervention group, and the difference was statistically significant (P<0.05).ConclusionTracheoscopy intervention treatment in the initial period of CAP not only significantly improves the efficacy, but also significantly reduces treatment costs and length of hospitalization, hence it is worth clinical promotion.
ObjectiveTo explore the safety and efficacy of the treatment of peripheral bronchopleural fistula with customized silicone plug through bronchoscope. MethodsA total of 19 patients with BPF admitted to Hunan Provincial People’s Hospital from July 2017 to May 2023 were included. Detailed medical records of the patients were collected, including etiology, fistula location, treatment methods, complications, and effective rates, to assess the safety and efficacy of customized silicone plug occlusion. ResultsThe average age of the 19 patients was 61.58 years (range from 42～84 years). The fistulas were located at the right upper lobe in 8 cases, the right middle lobe in 2 cases, the right lower lobe in 2 cases, the left upper lobe in 2 cases, and the left lower lobe in 5 cases. Causes included 9 cases after pneumonectomy, 6 cases of spontaneous pneumothorax, 1 case post Microwave Ablation Therapy for lung nodule, 1 case of advanced lung cancer under radiotherapy and chemotherapy, 1 case of candidal pneumonia, and 1 case of pulmonary tuberculosis. 15 patients were successfully occluded for the first time, 1 case failed to place the plug, and 3 cases had silicone plug dislodgement within 1 week after the procedure, with a short-term effective rate of 73.68% (14 cases). A total of 40 customized silicone plugs were placed, with an average of (2.10±0.74), and the mean diameter of the plugs used was 6.4 mm, with a range of 3 to 9 mm. Fifteen patients were recruited for long-term follow-up, with a median follow-up time of 15 months (range from 1.5 to 53 months). One patient developed a new fistula on the 45th day, who was treated with a combined small Y-type single bullet-covered stent for occlusion. One patient died of severe pneumonia 3 months postoperatively, and one died of type II respiratory failure at the 30th month, both deaths were unrelated to the interventional procedure. The long-term effective rate was 68.42% (13 cases). ConclusionPlacing customized silicone plugs through bronchoscopy can rapidly and effectively occlude peripheral BPF, with satisfactory long-term outcome.

ObjectiveTo compare the efficacy and safety of computed tomography (CT)-guided percutaneous versus electromagnetic navigation bronchoscopy (ENB)-guided microwave ablation (MWA) for the treatment of pulmonary nodules. MethodsA retrospective analysis was conducted on the data of high-risk pulmonary nodule patients who underwent MWA at the Nanjing Drum Tower Hospital between 2022 and 2023. The pathological diagnosis rate, complications, and progression-free survival (PFS) rate were compared between the CT group and the ENB group. ResultsThere were 61 patients in the CT group, including 30 males and 31 females, with an average age of (67.22±9.13) years. There were 53 patients in the ENB group, including 29 males and 24 females, with an average age of (65.29±13.76) years. The pathological diagnosis rate in the CT group was slightly higher than that in the ENB group (88.52% vs. 71.69%, P=0.03). However, the ENB group exhibited a lower incidence of perioperative complications, including pneumothorax (16.39% vs. 3.77%, P=0.03), hemoptysis (19.67% vs. 5.66%, P=0.05), and pain (22.95% vs. 7.55%, P=0.03). There was no statistically significant difference in PFS rate between the two groups [HR=1.17, 95%CI (0.23, 5.81), P=0.85]. ConclusionBoth CT-guided and ENB-guided MWA are effective treatment modalities for high-risk pulmonary nodules.
Objective To explore the clinical diagnostic value of transbronchial cryobiopsy (TBCB) for lung diseases. Methods All patients who underwent TBCB in the bronchoscopy room of West China Hospital, Sichuan University from November 5, 2020 to August 7, 2024 were consecutively included. Clinical information of the patients was collected, and the distribution of pathological diagnosis, clinical diagnosis, and the consistency between the two were statistically analyzed. The distribution of diagnosis and the consistency with pathological diagnosis of interstitial lung disease (ILD) were analyzed. The distribution of diagnosis of patients who underwent more than two lung biopsies was summarized. Results A total of 351 TBCB patients were included. The concordance rate between the overall pathological diagnosis and the clinical diagnosis was 68.66%. Among 351 patients who underwent TBCB, 199 cases were diagnosed as ILD by pathological diagnosis, and the consistency rate with the clinical diagnosis was 90.45%. 22 cases were pathologically suggested or suspected of tumor by pathology, and the final consistency rate with clinical diagnosis was 95.45%. Descriptive pathological conclusions were found in 74 cases. The clinical diagnosis of ILD was 255 cases, and the diagnostic rate of TBCB was 71.76%. 83 cases of immune-related ILD (diagnostic rate 83.13%); 75 cases of idiopathic interstitial pneumonia (diagnostic rate 44.00%). There were 59 cases of ILD with cysts and/or air spaces (diagnostic rate 83.05%). 33 cases of exposion-associated ILD (diagnostic rate 81.82%); 5 cases of pulmonary sarcoidosis (diagnostic rate 100.00%). Among them, 28 patients underwent lung biopsy more than twice, and the disease distribution was mainly ILD. ConclusionTBCB has significant value in the auxiliary clinical diagnosis of lung diseases, especially interstitial lung diseases, with the greatest advantages in the auxiliary diagnosis of pulmonary alveolar proteinosis, tumors, and idiopathicinterstitial pneumonia.
