    The precise investigation of tumor extent is very important for the decision of treatment strategy. In particular, extrabronchial invasion and peribronchial nodal metastasis influence the determination of clinical staging and operation method. The purpose of this study was to investigate the usefulness of endobronchial ultrasonography (EBUS) for evaluating the depth of bronchial wall invasion and nodal swelling by comparing its results to those of chest computed tomography and pathology. A total of 32 patients in whom tumors were detected out by bronchoscopy (30 primary lung cancers and 2 metastatic lung tumors) were entered into this study. The EBUS findings were obtained using thin ultrasonic probes (20 MHz, radial scanner) UM3R, EUM-3 and MH240 (Olympus, Japan). Lymph node metastasis was determined when the shape was round and the diameter exceeded 10 mm. Bronchoscopic findings of the tumors were 17 nodular, 8 polypoid, 6 thickened types and 1 case of submucosal invasion. Based on the relationship between tumor and bronchial cartilage, EBUS images revealed 13 intra-bronchial and 19 extra-bronchial invasions, which results were consistent with microscopic findings. The EBUS images could visualize hilar and intra-pulmonary lymph nodes (#10, 11,12, 13) well. In particular, intra-pulmonary lymph nodes were imaged by EBUS better than those by chest CT. In conclusion, EBUS is expected to be a useful modality for the evaluation of bronchial tumor invasion and nodal metastasis.

    Background. In comparison with body surface ultrasonographic techniques, progress in transtracheal endoscopic ultrasonography (TUS) software such as Doppler etc. has been delayed especially with regard to blood flow display and functional analysis of the lesion. Purpose. In this report, we used an electrical scan catheter for intravascular ultrasound (IVUS) and a miniature electrical linear scan by the transtracheal approach, and examined whether blood flow display of the pulmonary artery was possible. Methods and Results. First, the pulmonary artery of the peripheral lung was observed. IVUS In-Vision made by EndoSonic Co. was used. Using the electrical scan catheter, it is possible to display the blood flow in real-time and colored by ChromaFlo. The trachea of an SD rat was incised, and the electrical scan catheter was inserted. After the catheter was inserted to the peripheral bronchi, the pulmonary artery and the bronchi were observed. Blood flow of the pulmonary artery was depicted by ChromaFlo in orange. Next, central blood vessels were observed using a UST-5531 electrical linear scan (Aloka). It is possible to display blood flow in colored Doppler and power Doppler. UST-5531 was fixed in the BF-3C-40 which is 3 mm in diameter, and which was inserted into bronchi, with the linear probe in direct contact with the bronchial wall, and the blood vessels were observed transbronchially. Not only the blood flow of great vessels such as the aorta and pulmonary artery were displayed, but it was also possible to display the blood flow of lymph nodes which were colored. Conclusions. In the future, we want to improve the development of respiratory organ-exclusive TUS in which the colored display of blood flow is possible and the functionality is higher.

    We evaluated the utility of a newly developed autofluorescence bronchoscope, D-Light AF system (Karl Storz, Tuttlingen, Germany) which was installed in Japan for the first time to localize bronchial lesions such as dysplasia, early cancer and determine the extent of superficial invasion of advanced lung cancer. The D-Light AF system is equipped with a conventional xenon lamp as the light source and 3 different modes, white light (WL) mode, autofluorescence (AF) mode and 5-aminolevulinic acid (ALA) mode are available for observation. The blue excitation light (380 to 440 nm) is used for AF mode and the power at the tip of the bronchoscope is 50 mW. We performed autofluorescence diagnosis using this system in 3 cases with abnormal sputum cytology findings, 2 cases of early lung cancer, 2 cases of recurrence after photodynamic therapy (PDT) for early cancer and 2 cases of advanced cancer. Two of the 3 cases with abnormal sputum cytology findings showed positive finding on AF mode and the results of the biopsies showed dysplasia. The other case who was diagnosed later as peripheral lung cancer showed negative findings on WL and AF modes. Two cases of early cancer showed positive findings on AF mode and in one case, fluorescence diagnosis using AF and ALA mode was performed again just before the PDT laser irradiation at 48 hours after Photofrin injection intravenously. The AF mode image was better for the detection of the fluorescence of Photofrin from the lesion than the ALA mode. Two cases of recurrence after PDT showed positive findings on AF mode, however, the reaction site, including the normal site of previous PDT, also showed positive findings. Therefore, autofluorescence diagnosis is not considered useful for the detection of recurrence after PDT for early cancer. For the detection of superficial bronchial tumor invasion in the two cases of advanced cancer, the AF mode image of this system clearly showed the margin of tumor invasion. The characteristics of the D-Light AF system showed a direct image (not an indirect pseudo-image),is compact and easy to handle and makes it easy to change between white light and blue light. The image of the D-Light AF system using conventional xenon lamp as a light source showed as high quality as the LIFE system which is equipped with a laser system. We concluded that the D-Light AF system is a promising second generation fluorescence bronchoscopy system for the detection of premalignant and malignant lesions.

    Inner walls of fifteen peripheral pulmonary cavitary lesions were observed directly by an ultra-fine fiberoptic bronchoscope (Olympus BF-XP40) . The cavities were classified into two groups according to their appearance. One was the "red cavity" group that showed an overall view of a red inner wall with no visible necrotic changes. The other was the" necrotic cavity" covered with necrotic tissue throughout, or in many areas of the inner wall, even with partial hemorrhagic or reddened areas. The red cavity cases had a relatively acute clinical course, ralsing the possibility that their drainage bronchus had intramural edematous changes. In carcinomatous red cavities, moreover, a checkvalve mechanism or the inherent cavitating nature of the tumors could have been implicated in the pathogenesis of the formation of their cavities. The ultra-fine fiberoptic bronchoscope is, therefore, a valuable tool for not only confirming the diagnosis of cavitary lesions but also for clarifying their etiology.

    A 54-year-old woman presented with complaints of repeated episodes of pyrexia and productive cough. Chest X ray and CT films showed an endobronchial tumor in the right upper lobe bronchus, and obstructive pneumonia of the right upper lobe. Bronchoscopy revealed a smooth-surfaced tumor protruding into the right upper lobe bronchus. Bronchoscopic biopsy suggested an endobronchial leiomyoma. Right upper lobectomy was performed because of recurrent obstructive pneumonia. The resected specimen contained a smooth-surfaced tumor, 10 mm in size, protruding into the right upper bronchial lumen with a base attached to the right B^2 bronchus. The specimen showed organizing pneumonia with necrosis in the right S^3 region. Primary benign tumors of the lung are relatively rare and leiomyoma of the lung is particularly rare. We report a case of bronchial leiomyoma with recurrent obstructive pneumonia.

    A 72-year-old man was admitted to our hospital because of cough and hemosputum. Chest CT scan and bronchoscopy revealed a tumor about 1.5cm in diameter in the trachea. Because he had previously undergone right renal resection due to renal cell carcinoma, the tumor was suspected to be endotracheal metastasis from renal cell carcinoma, and it was definitively diagnosed by a bronchial biopsy. The tumor caused a subtotal tracheal obstruction, and showed hypervascularity and a tendency to bleed. Argon plasma coagulation (APC) was performed to stop bleeding from biopsied tumor, control superficial bleeding and reduce the tumor volume. The tumor was completely resected using an electorosurgical snare, without bleeding. APC is thought to be a useful and safe method of bronchoscopic inter- vention for tracheobronchial tumors.

    Background. Bronchial stenosis is one of the most serious complications of pulmonary tuberculosis. We report a case of second nitinol stent implantation performed because of obstruction at a site proximal to the initially implanted nitinol stent in the left main bronchus. Presentation. A 66-year-old woman with pulmonary tuberculosis had been treated by isoniazid, rifampicin and ethambutol for 1 year. Dyspnea and left lung atelectasis appeared on November 28,1999. Bronchoscopy showed complete obstruction, so we performed laser ablation. Dyspnea and left lung atelectasis immediately improved. Other respiratory symptoms recurred 9 months later. We treated with laser ablation, balloon dilatation and nitinol stent implantation in the left main bronchus. Nine months after stent implantation, dyspnea and left lung atelectasis recurred, in August 2001. Because obstruction of the proximal site of the implanted stent was seen on bronchoscopy, we treated with laser ablation, balloon dilatation and nitinol stent implantation proximal to the implanted stent in the left main bronchus. Conclusion. This case showed that nitinol stents can be useful for the management of bronchial stenosis after pulmonary tuberculosis.

    Background. Although the Dumon Y-stent is useful to prevent airway stenosis due to tumor invasion into the tracheo-carinal region, usage of this type of stent has been limited, because it requires a rigid bronchoscope. Purpose. We report here a method of inserting the Dumon Y-stent by a flexible bronchoscope. Methods. At the one distal end of the bifurcated portion of the stent, a small hole was made to be grasped by small forceps through the instrumentation channel from the inner side of the stent. Under local anesthesia of the airway with 4%lidocaine, the stent was inserted orally to the trachea by a flexible bronchoscope. Results and Conclusions. Insertion of the Dumon Y-stent while observing the tracheobronchial lumen is simple and safe by this method. This method should be useful in the outpatient department, because general anesthesia is not needed and the operation time is short.

    A 30-year-old man was admitted with dysphagia and fever. The chest CT scan showed a mediastinal tumor. Fiberoptic bronchoscopy and esophagoscopy examinations revealed a submucosal tumor in the esophagus and left main bronchus. Sputum culture and smear and PCR method for acid-fast bacilli were negative. The histological findings from the esophagus and bronchus revealed non-specific inflammatory changes which could not be definitively diagnosed. After 2 months of culture of esophageal specimens, M. tuberculosis was isolated. The case was diagnosed as M. tuberculosis which extended to the esophagus and bronchus.

    A 17-year-old girl was referred with exertional dyspnea, precordial pain, neck pain, and subcutaneous crackling sensation which developed during defecation. Chest X-ray and chest CT scans revealed marked mediastinal, subcutaneous, retroperitoneal, and pericardial emphysema, but no evidence of pneumothorax. Bronchoscopy was performed, but no airway injury was discovered. Because there was no other cause of emphysema, such as trauma, a diagnosis of spontaneous mediastinal, pericardial, and retroperitoneal emphysema was made. The patient had suffered from an eating disorder for 15 months, and showed marked weight loss (height:158cm;weight:33kg;BML=13.2;weight loss of 20 kg in 18 months), amenorrhea, fatty liver, and hepatic dysfunction probably due to extreme malnutrition. Anorexia nervosa was diagnosed by the psychiatric department of our hospital. After admission, she received conservative therapy such as rest and fluid infusion to improve her hepatic dysfunction and malnutrition. Psychiatric treatment was also provided. After initial worsening of her emphysema for several days, both the emphysema and the eating disorder improved. It was considered that the emphysema was caused by fragility of the connective tissues around the airways, resulting from malnutrition due to anorexia nervosa.
