Objective To investigate the feasibility, curative effect and perioperative treatments of lobectomy for pulmonary diseases by complete videoassisted thoracoscopic surgery (VATS). Methods Fiftysix patients of pulmonary diseases were treated with thoracoscopic lobectomy (including mediastinal and hilar lymph node dissection for malignant diseases) from March 2006 to November 2007 in our Department. Twelve right upper lobectomy, three right middle lobectomy, fifteen right lower lobectomy, nine left upper lobectomy, fourteen left lower lobectomy and three bilobectomy were carried out. The bilobectomy included one right upper and middle lobectomy, two right middle and lower lobectomy. Mediastinal and hilar lymph node dissection was simultaneously performed in the malignant cases. The feasibility, safety and postoperative complications were retrospectively analyzed. Results Fiftytwo patients (92.8%) were performed successfully by complete VATS. The median operative duration and blood loss were respectively 107±29min(from 45min to 168min) and 121±32 ml(from 50ml to 310ml). The incision in two cases (3.6%) were elongated to around 8 cm, the ribs were retracted, and the operations were completed by the help of VATS. Another two patients (3.6%) were changed to conventional thoracotomy for pneumonectomy or hemostasis. The postoperative pathology diagnosis was lung cancer in thirty nine, tuberculoma in seven, inflammatory pseudotumor in four, indurative angioma in four, bronchiectasis in one and metastasic chondrosarcoma in one. There was no surgical mortality. One case suffered from atelectasis in the middle lobe postoperatively and was cured by phlegm suction with bronchoscopy. Two air leakage healed automatically in three days. No other severe complications was observed. The average postoperative hospitalization was 8.9±3.1 d(from 8 d to 14 d). Conclusion Lobectomy for pulmonary diseases by complete VATS is technically fieasible, safe, minimally invasive with less complications and fast rehabilitation.
Due to their diverse types, complex causes, high incidence, and difficult treatment, lung diseases have become major killers threatening human life and health, and some lung diseases have a significant impact on alveolar morphology and histology. Numerical simulation of alveolar mechanical response, alveolar flow field information, multiphase flow, and material transport based on computational fluid dynamics is of great significance for lung disease diagnosis, clinical treatment, and in vitro experiments. Starting from the simplification and pathological differences of geometric and mechanical models, this paper analyzes and summarizes the conditions and application scenarios of the airflow dynamics calculation method in pulmonary alveoli, to provide a reference for further simulation and application of the alveolar region.
Objective To investigate clinical outcomes of complete video-assisted thoracoscopic lobectomy and summarize our preliminary experience. Methods Clinical data of 60 consecutive patients who underwent complete video-assisted thoracoscopic lobectomy in General Hospital of Chengdu Military Command from March 2010 to August 2011 were retrospectively reviewed. There were 37 male patients and 23 female patients with their median age of 52.1 （17-77） years. There were 7 patients undergoing left upper lobectomy， 19 patients undergoing left lower lobectomy， 12 patients undergoing right upper lobectomy， 3 patients undergoing right middle lobectomy， 17 patients undergoing right lower lobectomy， and 2 patients undergoing combined right middle and lower lobectomy. Results The average operation time was 161 （50-270） minutes， average intra-operative blood loss was 310 （50-800） ml， average number of lymph node dissection was 13.4 （6-29）， average postoperative thoracic drainage was 950 （250-2 800） ml， average duration of thoracic drainage was 4.6 （3-11） days， average intensive care unit stay was 1.2 （1-3） days， and average postoperative hospital stay was 7.7（4-14） days. None of the patients had any severe postoperative complication. Fifty-two patients were followed up for 7 to 24 months， and 8 patients were lost during follow-up. During follow-up， 5 patients had lung cancer metastases， including 2 patients with mediastinal lymph node metastases and 3 patients with distant metastases. After chemoradiotherapy，3 patients lived well but 2 patients died. None of the other patients had any severe complication during follow-up. Conclusion Complete video-assisted thoracoscopic lobectomy is a safe and effective surgical strategy for patients with benign or malignantpulmonary disease.
ObjectiveTo summarize the clinical manifestations, basic diseases, imaging features, drug sensitivity results and recovery of Mycobacterium Kansasii pulmonary disease patients to enhance understanding of the disease. Methods The clinical data of 116 patients with Mycobacterium Kansas pulmonary disease diagnosed in Guangzhou chest hospital from January 2019 to September 2024 were analyzed retrospectively. Results The 116 patients with Mycobacterium kansasensei lung disease were 67 males and 49 females, aged 27 to 92 years, with clinical manifestations of cough and sputum (102 cases) and hemoptysis (48 cases) as the predominant symptoms. There were 98 cases with history of bronchiectasis, 8 cases with cancer,18 cases with cardiovascular disease, 22 cases with chronic obstructive pulmonary disease, 10 cases with diabetes mellitus, 9 cases with rheumatoid immune system disease, 5 cases with pulmonary aspergillus infection, 2 cases with asthma, and 10 cases without underlying disease. All of them had lung shadows on imaging, including 30 cases with simple bronchodilatation manifestation, 48 cases with bronchodilatation combined with cavitation, 10 cases with patchy streak shadow, 18 cases with patchy streak shadow combined with cavitation, and 10 cases with nodules combined with cavitation. The results of drug sensitivity showed that the resistance rate of more than 50% was isoniazid (89.66%), streptomycin (75.87%), amikacin (72.41%), and isoniazid para-aminosalicylate (Likely Lung Disease) (56.90%); while the sensitivity rate of more than 50% was rifabutin (100%), moxifloxacin (94.83%), rifampicin (93.10%), prothioisonicotinamide ( 91.38%), levofloxacin (89.66%), ethambutol (84.48%), and linezolid (79.31%). 76 of the remaining 98 of 116 patients had negative sputum cultures within 1 year, with the exception of 12 who were left untreated and 6 who did not complete treatment. The 116 patients with Mycobacterium kansasensei lung disease presented with chronic cough, sputum, and hemoptysis, and most of them were combined with structural lung diseases such as bronchiectasis, or with underlying diseases such as chronic obstructive pulmonary disease and diabetes mellitus. Imaging features show pulmonary shadows. Moreover, Mycobacterium kansasii shows high sensitivity to most conventional antituberculosis drugs, which may result in a higher cure rate compared with other types of nontuberculous mycobacterial lung disease. Therefore, timely and well-conducted strain identification and drug sensitivity testing are essential for the development of a targeted treatment program that can significantly improve patient outcomes. Conclusions Clinical manifestations of 116 patients with Mycobacterium kansasense lung disease were characterized by chronic cough, sputum and hemoptysis, which were mostly combined with structural lung diseases such as bronchiectasis. The imaging features show pulmonary shadows. Mycobacterium kansasii exhibits a higher sensitivity rate to most conventional anti-tuberculosis drugs, which may result in a higher cure rate in treatment compared to other types of nontuberculous mycobacterial lung diseases. Therefore, timely and comprehensive species identification and drug susceptibility testing are crucial for formulating targeted treatment regimens, which can significantly improve patients' treatment outcomes.
ObjectiveTo analyze the disease burden and temporal trends of chronic obstructive pulmonary disease (COPD) attributable to air pollution in China from 1990 to 2021. MethodsUtilizing data from the Global Burden of Disease Study 2021 (GBD 2021), we assessed the burden of COPD attributable to air pollution in China through metrics including death counts, disability-adjusted life years (DALYs), age-standardized mortality rate (ASMR), age-standardized DALY rate (ASDR), annual percentage change (APC), and average annual percentage change (AAPC). A Bayesian Age-Period-Cohort (BAPC) model was employed to project future trends in COPD burden attributable to air pollution. ResultsIn 2021, China’s ASMR and ASDR for COPD attributable to air pollution were 32.57 and 533.84 per 100,000 population, respectively, exceeding global averages. From 1990 to 2021, both ASMR and ASDR exhibited significant declining trends, with AAPCs of −5.24% (95% CI −5.78% to −4.70%) and −5.28% (95% CI −5.75% to −4.81%), respectively. The burden intensified with advancing age and was disproportionately higher among males compared to females. BAPC projections indicate a continued decline in COPD burden from 2022 to 2035, with ASMR expected to decrease from 56.40 to 23.02 per 100,000 and ASDR from 900.14 to 408.64 per 100,000. Conclusion Despite sustained reductions in the burden of COPD attributable to air pollution in China from 1990 to 2021, with further declines anticipated through 2035, national rates remain elevated relative to global benchmarks. Male and elderly populations bear the highest burden, underscoring the urgency for targeted interventions to mitigate air pollution exposure and address health disparities in vulnerable demographics.
Abstract： Objective To explore the method and effect of single utility port video-assisted thoracoscopic surgery （VATS） for the treatment of pulmonary diseases. Methods From Jan. 2008 to Jun. 2010, 158 patients with pulmonary diseases were treated by single working pore VATS in the Department of Thoracic Surgery of West China Hospital, Sichuan University. Their diseases included 6 kinds of different lesions, such as pneumothorax（inflammatory pseudotumor, hamartoma, lymphangiomyomatosis） , lung tuberculoma, and lung carcinoma. Seventy patients had definite diagnosis before their operation, and the others had their final diagnosis by intraoperative frozen section evaluation and postoperative pathology examination. All the resections were carried out by pure thoracoscopic procedures with two ports, one working pore and one observing pore. A 28-Fr chest tube was placed to the pleural apex. Limited lung resection was performed in 151 patients, single lobectomy in 7 patients, and simultaneous bilateral operation in 6 patients. Results For limited lung resection patients, the average operation time was 18 （5-60） min, and the average blood loss was 33 （5-95） ml. No patient needed intraoperative blood transfusion . Ten patients received an increased pore, including 6 patients with pleural cavity obliteration or abundant pleural adhesions, and 4 patients with intraoperative bleeding . The average postoperative length of stay was 2.5 （2-4） days, and the average medical cost was 17 884 （15 476-25 387） Yuan. For patients undergoing lobectomy and lymph node dissection, the average operation time was 128 （50-220） min, and the average blood loss was 180 （80-478） ml. No patient needed intraoperative blood transfusion. One patient received an increased pore. The average postoperative length of stay was 4.7 （4-7） days, and the average medical cost was 42 385 （38 965-57 695） Yuan. No perioperative death or severe complications were observed in present series. Conclusion Single utility port VATS is a safe and efficient procedure with good patient recovery. It is a method of choice for selected patients with pulmonary diseases.
Electrical impedance tomography (EIT) is a new non-invasive functional imaging technology, which has the advantages of non-invasion, non-radiation, low cost, fast response, portability and visualization. In recent years, more and more studies have shown that EIT has great potential in the detection of lung diseases and has been applied to early diagnosis and treatment of some diseases. This paper introduced the basic principle of EIT, discussed the research and clinical application of EIT in the detection of acute respiratory distress syndrome, chronic obstructive pulmonary disease, pneumothorax and pulmonary embolism, and focused on the summary and introduction of indicators and functional images of EIT related to the detection of lung diseases. This review will help medical workers understand and use EIT, and promote the further development of EIT in lung diseases as well as other fields.
ObjectiveTo investigate the current status of outpatient pain management in patients with pulmonary disease after surgery by WeChat and to provide a basis for postoperative pain management.MethodsA total of 449 patients who underwent thoracic surgery in our hospital from December 2017 to May 2018 were enrolled, including 156 males and 293 females with an average age of 22-83 (55.54±11.17) years. Brief Pain Inventory was adopted for pain assessment in 24-48 hours after discharge and 24 hours after removal of from the wound.ResultsTotally 98.22% of the patients reported that they suffered from pain in 24-48 h after discharge, most pain position was still at drainage port (45.21%), the overall pain score was 2.75 (2.00, 3.25) points, and 82.85% of patients adopted physical methods to relieve pain. After removal of stitches at the drainage port, 79.29% of the patients suffered from pain, the pain site was mainly at the drainage port (47.88%), and the overall pain score was 1.75 (1.25, 2.25) points, and 73.94% of patients adopted physical methods to relieve pain. The score of the overall influence degree of pain on patients was 2.29 (1.86, 2.86) points and 1.86 (1.29, 2.43) points, while pain had the greatest influence on sleep and mood. The scores were 4.00 (3.00, 5.00) points, 3.00 (2.00, 4.00) points and 2.00 (1.00, 4.00) points, 3.00 (2.00, 4.00) points, respectively.ConclusionUnder the concept of enhanced recovery after surgery, the overall pain level of patients with pulmonary disease after discharge is mild pain, but the application rate of drug analgesia in patients is low. The overall effect of pain on postoperative patients with lung cancer is low, but it has a great impact on sleep and mood. Medical staff should strengthen the pain education for patients in order to improve their pain self-management ability.
