Therapeutic bronchoscopy in lung cancer. Laser therapy, electrocautery, brachytherapy, stents, and photodynamic therapy 总被引:4,自引:0,他引:4
Therapeutic bronchoscopic techniques such as LPR, EC, brachytherapy, stents, and PDT are effective tools in the palliation and local control of lung cancer. Palliation of malignant tracheobronchial obstruction by LPR, stents, brachytherapy, PDT, or a combination thereof results in relief of dyspnea, hemoptysis, and postobstructive pneumonia. Importantly, it avoids intubation in patients with respiratory distress and facilitates the weaning of patients from MV. In the exciting field of lung cancer screening and treatment of early lung cancer, PDT, brachytherapy, EC, and LPR may represent treatment alternatives to surgical resection, especially in a select group of patients with high surgical risk or favorable endobronchial lesions. Clinicians await the results of future studies, which will (1) better define the impact of each treatment modality on patient care in terms of cost, survival, and improvement in quality of life, and (2) determine the optimal combination therapy relative to bronchoscopic and conventional treatment for effective palliation and cure of lung cancer. 相似文献

Post-obstructive pneumonia is the result of airway obstruction, commonly due to lung cancer. The majority of patients with
lung cancer are non-operable and incurable at initial presentation. The clinical course of these patients is steadily downhill
with complicating events such as post-obstructive pneumonia, respiratory failure, pleural effusion, and severe debilitation.
Non-invasive conventional options for post-obstructive pneumonia include broad-spectrum antibiotics, combined with attempts
at relieving the obstruction using radiation therapy. There is scant literature on the natural course of post-obstructive
pneumonia, disease resolution, and optimal treatment. With the recent surge in technologic advances in interventional pulmonology,
multiple airway recanalizaton options are now available. In this paper, we describe the causes of post-obstructive pneumonia,
and the role of interventional pulmonary procedures in establishing an open airway. 相似文献

Even though benign tracheobronchial tumors are quite rare, they still can induce airway obstruction, result in suffocation, and need emergent management to remove the obstructing lesions and make the respiratory tracts unobstructed. Although the preferred therapy is surgery, it is still difficult to deal with the tumors in some cases, and the complications of surgery are common. Therefore, bronchoscopic managements, such as Nd: YAG laser, electrocautery, APC and Cryotherapy, are very important to treat benign tracheobronchial tumors and can cure most of them.The efficacy of therapeutic endoscopy for the treatment of patients with benign airways obstruction has been established. However, in order to maximally eradicate the benign tumors with minimal damage to patients, the success of bronchoscopic managements for the treatment strongly depends on the diligent identification of the various factors, including the location, size, shape of tumor, and the age, status, cardio respiratory function of patients, and full comprehension of the limits and potential of each particular technique.Because the advantages and disadvantages of above mentioned interventional methods, single method can not solve all clinical issues. Therefore, in order to remove benign tracheobronchial tumors completely, and reduce the incidence of recurrence as far as possible, many doctors combine several methods of them to treat complicated benign tracheobronchial tumors. This article reviews the core principles and techniques available to the bronchoscope managing benign tracheobronchial tumors. 相似文献

The field of interventional pulmonology has rapidly expanded to include the management and treatment of complex diseases of the chest. The management of central airway obstruction, pleural disease diagnosis, treatment and palliation, advanced bronchoscopic techniques to aid in the diagnosis of lung cancer and innovative therapies to treat asthma and COPD have all emerged over the past decade. As astute clinicians, we are all aware of the risks and benefits of using these therapies to treat our patients. In order to appropriately treat and manage these often complex medical situations, the physician should have an expert knowledge of all available modalities, the expertise to safely perform the procedure and the ability to minimize the risk of and manage the associated complications that may arise. In this chapter we review and update some of the bronchoscopic and pleural interventions offered by interventional pulmonologists as well as the associated complications and management. 相似文献

Hamartomas are the most common benign tumors of the lung. It is most common peripherally in the parenchyma as solitary nodule or endobronchial lesion. Endobronchial form may cause obstruction of airway, atelectasis and recurrent pneumonia. Endobronchial hamartomas may be treated by surgical intervention or bronchoscopic excision (with rigid or flexible procedures). We are presenting a case of endobronchial hamartoma successfully treated with bronchoscopic electrocautery without a need for surgical removal. 相似文献

Interventional bronchoscopy, together with other domains of interventional pulmonology, has experienced tremendous technological advances. Diagnostic applications include endobronchial ultrasound, which enables endoscopists to see through airway walls. White light videobronchoscopy, autofluorescence imaging, and narrow band imaging have enhanced the ability to detect early lung cancer at a preinvasive stage. Electromagnetic navigational bronchoscopy, ultrathin bronchoscopy, and virtual bronchoscopy increase the diagnostic yield of biopsy of small peripheral lung lesions. The options that are currently available for the relief of central airway obstruction are also numerous, with both flexible and rigid bronchoscopic applications. Stents, although dichotomized to silicone and metal, come in various sizes and shapes to suit the requirements of the pathology being treated. Ablative techniques are categorized into those with an immediate effect and those with a delayed effect. Laser, electrocautery, and argon plasma coagulation can immediately relieve obstruction and control hemoptysis, whereas cryosurgery, brachytherapy, and photodynamic therapy have established roles in subacute airway obstruction and in the treatment of early lung cancer. Microdebriders have recently been added to the armamentarium of modalities for mechanical debulking of tumor. Distal airway obstruction has also been targeted with bronchial thermoplasty treatment of refractory asthma and with bronchoscopic lung volume reduction for the management of severe emphysema. This array of new technology has fostered collaborative work with a wide range of other medical specialties to deliver safer, more effective, minimally invasive treatment. 相似文献

Tracheobronchopathia osteochondroplastica (TPO) is an uncommon benign disease of unknown etiology characterized by multiple cartilaginous or bony submucosal nodules, which project into the tracheobronchial lumen. The nodules originate in the airway cartilages and thus typically spare the posterior membranous wall of the airways. The disorder is more common in men and the diagnosis is usually made in the fourth through sixth decades of life. There is no relationship to smoking or other systemic disorders. The disease is manifested by chronic cough and wheezing, which frequently lead to the mistaken diagnosis of asthma. Other pulmonary symptoms include dyspnea and hemoptysis. One of the complications is the increased incidence of recurrent respiratory infections. The pulmonary symptoms and complications are the consequence of narrowing and thickening of the airway walls. Even though roentgenologic imaging studies may indicate the diagnosis, bronchoscopy is the most definitive diagnostic test. The bronchoscopic appearance alone is diagnostic of the disease, and biopsy of the airway lesions is seldom, if ever, required. Although there is no specific therapy for this disorder, management of tracheobronchopathia osteochondroplastica includes bronchodilators, prompt treatment of pulmonary infections, and bronchoscopic dilatation when indicated. 相似文献

Tracheobronchomalacia (TBM) and excessive dynamic airway collapse (EDAC) are both dynamic forms of central airway obstruction characterized by a decrease of >/=50% in the cross-sectional area of the tracheobronchial lumen. The differences between these two entities, however, are not uniformly accepted in the medical community. While TBM is characterized by a weakness of the tracheobronchial cartilaginous structures, EDAC is marked by excessive bulging of the posterior membrane into the airway lumen during exhalation. These disease entities are probably underdiagnosed because they present with a variety of nonspecific symptoms similar to patients with other obstructive ventilatory disorders such as asthma and COPD. Diagnosis is confirmed by dynamic radiologic imaging studies or bronchoscopy. Current therapeutic management depends on the extent, type, and severity of airway abnormalities noted and the clinical presentation. Proposed management alternatives include conservative medical therapy, and minimally invasive and open surgical interventions. Inhaled bronchodilators should be used only if symptoms and ventilatory function improve after use. Continuous positive airway pressure acts as a pneumatic stent and should be considered as an alternative or additional therapeutic modality. Endoluminal stent insertion can improve symptoms and pulmonary function in patients with central airway obstruction and should be considered for patients with symptoms refractory to conservative therapy. Several open surgical procedures have also been performed over the years, including tracheostomy, airway splinting, tracheal resection and, more recently, external tracheal stents. Endobronchial laser therapy, resorbable stents, application of grafting materials used to support the collapsed airway as well as the use of cartilage regeneration techniques are experimental, and their efficacy in humans remains to be determined. Future studies should compare therapeutic interventions and outcomes such as functional status, ventilatory function, and bronchoscopic and radiologic appearances in order to define the costs and benefits of individual and combined treatment modalities. 相似文献

Interventional bronchoscopy in the management of airway stenosis due to tracheobronchial tuberculosis 总被引:22,自引:0,他引:22
STUDY OBJECTIVES: To assess the efficacy and complications of interventional bronchoscopic techniques in treating airway stenosis due to tracheobronchial tuberculosis. DESIGN: Case series. SETTING: Respiratory care centers at two tertiary care referral teaching hospitals in Japan, Hiroshima City Hospital and Okayama Red Cross Hospital. PATIENTS AND INTERVENTIONS: A total of 30 patients were admitted to the hospital with a diagnosis of tracheobronchial tuberculosis between January 1991 and January 2002. Of those 11 patients received interventional bronchoscopy, including stent placement, laser photoresection, argon plasma coagulation (APC), balloon dilatation, cryotherapy, and endobronchial ultrasonography (EBUS). One patient with complete bronchial obstruction underwent a left pneumonectomy. RESULTS: Six patients underwent stent placement after balloon dilatation, while the remaining five patients underwent only balloon dilatation. In six patients, Dumon stents were successfully placed to reestablish the patency of the central airways. Two patients first had Ultraflex stents implanted but had problems with granulation tissue formation and stent deterioration caused by metal fatigue due to chronic coughing. Dumon stents then were placed within the Ultraflex stents after the patient had received treatment with APC and mechanical reaming using the bevel of a rigid bronchoscope. In four patients, EBUS images demonstrated the destruction of bronchial cartilage or the thickening of the bronchial wall. The main complications of Dumon stents are migration and granulation tissue formation, necessitating stent removal, or replacement, and the application of cryotherapy to the granuloma at the edge of the stent. CONCLUSION: Interventional bronchoscopy should be considered feasible for management of tuberculous tracheobronchial stenosis. Dumon stents seem to be appropriate, since removal or replacement is always possible. Ultraflex stents should not be used in these circumstances because removal is difficult and their long-term safety is uncertain. EBUS could provide useful information in evaluating the condition of the airway wall in cases of tracheobronchial tuberculosis with potential for bronchoscopic intervention. 相似文献

BACKGROUND: Surgery is the choice treatment for symptomatic tracheal obstruction due to malignant thyroid disease. Few additional therapeutic alternatives are available: radiotherapy (RT), chemotherapy (CT) or radioiodine therapy (1311). Only few studies on interventional bronchoscopy (IB) as well as alternative or palliative procedures have been reported so far. This study is a retrospective report of results of IB performed in patients with severe tracheal obstruction due to advanced thyroid cancer. SETTING: Pulmonary and Endocrinology Units of a University Hospital. Patients and interventions: From January 2, 2000 to March 1, 2004 14 consecutive patients [5 males, mean age: 62.2+/-10.7 (SD) yr] underwent IB due to tracheal obstruction for anaplastic (ATC: 7 patients), differentiated (DTC: 5), medullary (MTC: 1) and non-epithelial malignant (NEMN: 1) thyroid cancer. Eight out of 14 patients had local advanced inoperable disease, 6 had local relapse after surgery, 1311 or RT. Ten out of 14 patients suffered from severe dyspnea. In 4 patients airway patency was maintained by insertion of a stent; in 3 the tracheal lesion was removed by Nd-YAG laser; in 7 both procedures were performed. RESULTS: All 10 patients with dyspnea showed an improvement in symptoms. Early and late complications were observed in 4 and in 3 patients, respectively. All but 4 DTC patients died 11.9+/-14.2 months after the diagnosis (4.20+/-5.1 after IB). In 4 DTC patients still alive 90.7+/-59.2 since diagnosis and 16.7+/-9.2 months since IB, the airway dilatations allowed further treatments like 131-I and/or RT. CONCLUSIONS: Interventional bronchoscopy, including Nd-YAG laser and airways stenting are alternatives to surgery in inoperable thyroid-induced tracheal obstruction. Moreover, airway dilatation improves dyspnea and may allow further treatment. 相似文献

A 35-year-old man had been exposed to the vapor of dimethyl sulfate which was split over the bed of a truck from an accidentally broken container. After receiving treatment at the critical care unit of our university hospital for respiratory failure, he was transferred to our ward with dyspnea persisting for one month. Chest X-ray showed diffuse nodular and infiltrative shadows and shadows suggestive of bronchial wall thickening. Bronchoscopy demonstrated tracheobronchial stenosis due to severe inflammation, and transbronchial lung biopsy revealed erosion and granulation in tissues of the bronchiolar walls. These findings suggested extensive inflammatory involvement of the respiratory tract extending from the trachea to the bronchioles. Treatment with antibiotics, especially agents with antipseudomonal activity, was effective against secondary pneumonia. Administration of corticosteroid for stenotic lesions of the airway was extremely beneficial. The clinical course of the respiratory lesion caused by dimethyl sulfate intoxication was following, including the bronchoscopic findings. The efficacy of treatment with corticosteroid and antibiotics was evaluated by successive bronchoscopic examinations of the lesions. 相似文献
