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.
Objective To explore the clinical value of pleura biopsy and partial pleura cryobiopsy via electronic bronchoscope in diagnosis of unknown exudative pleural effusion. Methods Diagnostic results of 563 patients with unknown exudative pleural effusion were analyzed retrospectively. Bronchoscope and routine pleura biopsy were performed in 187 patients. Bronchoscope and routine pleura biopsy plus partial pleura cryobiopsy were performed in 376 patients. Pathological positive rates of the two groups were compared. Results In the 187 patients examined by bronchoscope and routine pleura biopsy from 2006 to 2008, 161 patients obtained pathological positive results ( 86.1% ) . In the 376 patients examined by bronchoscope and routine pleura biopsy plus partial pleura cryobiopsy from 2009 to 2012, 354 patients acquired pathological diagnosis ( 94.1% ) . There was significant difference between the two groups ( P lt; 0.05) . The main complications were bleeding and local chest pain, and they can be controlled easily. Conclusions Electronic bronchoscope and pleura biopsy can obtain high detection rate of nearly 90% in diagnosis of unknown exudative pleural effusion especially when combined with cryobiopsy of partial pleura. Electronic bronchoscope combined with pleura biopsy or cryobiopsy is an alternative in clinical settings when thoracoscope is unavailable.
目的探讨肋骨骨折导致的创伤性肺不张治疗中应用电子支气管镜肺段灌洗治疗的效果 方法回顾性分析新疆医科大学第六附属医院2009年10月至2013年4月肋骨骨折导致创伤性肺不张73例行电子支气管镜肺段灌洗治疗患者的临床资料，其中男52例、女21例，年龄29～83（36± 5）岁。按治疗方式将患者分为两组：灌洗组（37例）行电子支气管镜肺段灌洗，对照组（36例）采用肺不张的常规治疗。比较两组临床效果。 结果灌洗组呼吸频率及心率减慢，动脉血氧饱和度升至95%以上，肺复张明显好于对照组，差异有统计学意义（P < 0.05）。 结论电子支气管镜肺段灌洗治疗肋骨骨折导致的创伤性肺不张直视下诊断明确，起效快，创伤小，疗效确切。
Objective To explore the efficacy and safety of bronchoscopy-guided radioactive 125I seeds implantation combination with chemotherapy for advanced central type lung cancer. Methods Sixty-six patients with central type lung cancer in stage Ⅲb or Ⅳ were enrolled in this study from May 2014 to July 2016. The patients were randomly divided into two groups, ie. bronchoscopy-guided seeds implantation combined with chemotherapy group (experimental group, n=30) and chemotherapy group (control group, n=36). All patients accepted GP regimen (gemcitabine plus cisplatin) chemotherapy and were followed up by CT and electric bronchoscopy (EB) examination 1, 3, 5 months later. According to WHO unified standard, the efficacy and adverse effects were evaluated . Results In the experimental group and the control group, the response rate (complete response plus partial response) was 80.00% and 50.00%, respectively. There was significant difference between two groups (P<0.05). The incidence rate of hemoptysis in the experimental group was significantly higher than that in the control group (P<0.05), but there was no significant difference between the two groups in the incidence rate of pneumothorax, fever or bone marrow suppression (allP>0.05). All adverse reactions were light and could be controlled. Conclusions The short-term clinical efficacy is better in the bronchoscopy-guided seeds implantation combined with chemotherapy group. The bronchoscopy-guided seeds implantation combined with chemotherapy is a safe and minimally invasive treatment for advanced central type lung cancer.
