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.
Nowadays, the development of the medical instrument industry makes rapid changes in clinical practice. Hybridization of latest technology is playing an increasingly important role in the diagnosis and treatment of disease. Especially, the trend of the integration of three-channel hybrid technology in diagnosis and treatment of early lung cancer has become increasingly obvious. This paper will focus on the technical advance of the three-channel multi- mirror robot and its application in the diagnosis and treatment of early lung cancer.
Malignant airway stenosis generally refers to airway lumen stenosis caused by various primary and metastatic malignant tumors and restricted airflow, which can be manifested as dyspnea to varying degrees or even asphyxia and death. It seriously affects the quality of life of patients with airway stenosis. With the continuous development of bronchoscope interventional techniques, various interventional therapies such as ablation, dilation and stent implantation can be used to reventilate the airway. Among them, ablation treatment is the most commonly used method. The methods of ablation treatment include cold, heat, photodynamic, local chemoradiotherapy, etc. This article will review the new applications of various methods used in the ablation treatment of malignant airway stenosis progress.

Objective To evaluate the diagnostic value and utility of flexible bronchoscopy in the preoperative assessment in patients with solitary pulmonary nodules (SPNs). Methods A total of 111 patients with SPNs of unknown origin treated between January and June 2016 were retrospectively enrolled. The clinical characteristics, bronchoscopy findings and surgical strategies were collected. Results In the total 111 cases, malignant and benign SPNs were 79 and 32 cases, respectively. The mean diameter of malignant SPNs was larger than that of benign SPNs [(2.04±0.58) vs. (1.70±0.75) cm, P<0.05]. Bronchoscopy identified 9 cases (8.1%) unsuspected findings. Surgeries were modified or cancelled in 3 patients (2.7%) because of bronchoscopy findings. Transbronchoscopy biopsies were performed in 26 patients, 9 of whom were diagnosed lung cancer preoperatively, with a sensitivity of 45% (9/20) and a specificity of 100% (6/6). Conclusions Flexible bronchoscopy can be contributed to diagnosis of SPN before surgery and determination of surgical strategies. It is suggested that flexible bronchoscopy could be included in the routine preoperative work-up of SPN.
Abstract： Objective To evaluate the effect of 100% carbolic acid via bronchofiberscope for the treatment of bron- chopleural fistula. Methods We retrospectively analyzed clinical data of 12 patients with postoperative bronchopleural fistula in Liaoning Tumor Hospital from February 2009 to March 2012. There were 11 male patients and 1 female patient with their average age of 58.0 （45-71） years. All the patients had primary lung cancer, including squamous cell carcinoma in 8 patients and adenocarcinoma in 4 patients， central lung cancer in 8 patients and peripheral lung cancer in 4 patients. Three patients were after right total pneumonectomy， 6 patients were after left total pneumonectomy， 2 patients were after right middle and lower lobectomy， and 1 patient was after left upper lobectomy. All the patients received 100% carbolic acid instillation via bronchofiberscope， and 0.5-1.0 ml carbolic acid solution was instilled on the mucosal surface around the fistula each time. The presence of bubbles in thoracic drainage was observed. If some bubbles remained, such treatment was repeated after 1 week. The effectiveness was analyzed. Results All the 12 patients were cured after carbolic acid treatment, including 8 patients after 5 times of carbolic acid instillation， 2 patients after 7 times of carbolic acid instillation， and 2 patients after 2 times of carbolic acid instillation. The average time for fistula closure was 33 days. All the patients were treated in our outpatient clinic except 2 patients who were too weak but cured after 42 days and 50 days of hospitalization respectively. Conclusion The use of 100% carbolic acid instillation via bronchofiberscope can provide satisfactory clinical outcomes for the treatment of bronchopleural fistula.
Objective To investigate the manifestations, diagnosis and treatment of tracheobronchopathia osteochondroplastica ( TO) . Methods Two cases of TO were described and 76 cases in the medical literature after 2000 were reviewed. Results TO usually manifests in adults, and affects both genders. The clinical presentation of TO is nonspecific. Bronchoscopy remains the gold standard for diagnosing this condition. Hard sessile nodules arising from the anterior and lateral walls of the airway,typically sparing the posterior membrane, are classic appearance that can be easily recognized. The CT scan is more sensitive and specific, which plays an important role in the diagnosis of TO. Bronchial biopsies disclose the abnormal presence of cartilage and bone tissue in the bronchial submucosa. To date there is nospecific treatment for the disease. Only a minority of cases develop into significant upper airway obstruction and require invasive procedures to remove or bypass the obstacle on affected airways. Conclusions TO is a stable or slowly progressive benign disease. Chest computed tomography and fiberoptic bronchoscopy are thebest diagnostic procedures to identify TO.
Abstract: Objective To compare the sensitivity and accuracy of autofluorescence bronchoscope (AFB) and white light bronchoscope (WLB) in airway examination for patients with central type lung cancer. Methods From September 2009 to May 2010, 46 patients including 36 males and 10 females with an average age of 62.1 years underwent both AFB and WLB procedures in People’s Hospital of Peking University. Among them, 35 were preliminary diagnostic cases and 11 were postoperative surveillance cases. Local anaesthesia of glottis and airway, and general anaesthesia with continuous intravenous drugs were given before electric bronchoscope was adopted. All patients underwent WLB examination followed by AFB procedure. All suspicious abnormal visual findings were recorded for biopsy and pathological examination. Results All procedures were carried out safely without death or severe complications. We performed bronchoscopy 48 times for all 46 patients and 159 tissues of various sites were taken out for biopsy and pathologic examination which showed 64 malignancies and 95 none malignancies. In 64 malignancies, AFB found all but WLB missed 15 with a missed diagnosis rate of 23.4%. Thirtysix times of examination were performed for the 35 preliminary diagnostic cases and 56 sites of malignancy were found. AFB found all, while WLB missed 12, and 6 sites of malignancy found by AFB were larger in size than those found by WLB. AFB detected 3 cases of multisite malignancy, but WLB missed these diagnoses. The results of AFB and WLB were the same for 26 patients. Twelve times of bronchoscopy were performed for the 11 postoperative surveillance cases and 8 sites of malignancy were found. AFB found them all while WLB missed 3 which were two recurrent cases during the early period after lung cancer surgery. The sensitivity of AFB and WLB was 100.0 % and 76.6%(Plt;0.05) respectively, and the negative predictive value of AFB and WLB was 100.0% and 84.5%(P=0.002) respectively. Conclusion AFB has a better sensitivity and negative predictive value than WLB in detecting mucous canceration lesions in central type lung cancer, and is more accurate in assessment of tumor margins, more sensitive in finding multiple lesions in airway and detecting early cancer recurrence in postoperative surveillance patients.
