    Rigid bronchoscopy under general anesthesia enables performing diagnostic and/or therapeutic procedures in the tracheobronchial tree. This technique is characterized by specific technical problems, insofar as the anesthesiologist and the operators share the same space, namely the airway. Several potential complications (hemorrhage inside the airway, threat to ventilation ...) may arise. These challenges render the ability to use the variable available techniques essential, as well as knowledge of the complications they could entail, and the ability to rapidly solve them. General anesthesia is usually total intravenous anesthesia, using short acting agents. Ventilation can be spontaneous, but more often insured using high-frequency jet ventilation. The hospital infrastructure and staff must have the expertise to perform this particular procedure, in order to limit the complication rate. PMID:25508517

    Bronchoscopy is the preferred method for collecting biological samples from the lower airways of subjects in clinical research. However, ensuring participation in clinical research can be challenging when the research includes an invasive procedure. For this report we reviewed the literature to look for information on participation in research bronchoscopy studies to better design our own study, the Bergen COPD Microbiome study (MicroCOPD). We performed a systematic literature search on participation in research bronchoscopy studies in February 2014 using the search engines of PubMed and EMBASE. The literature search resulted in seven relevant papers. Motivation was an end point in six of the seven papers, but reasons for declining participation and recruitment strategies also seemed important. Human subjects participate in research bronchoscopy studies for personal benefit and altruistic reasons. Inconvenience associated with research, in addition to fear of procedures, is considered a barrier. Radio, especially news stations, generated the most inquiries for a clinical study involving bronchoscopy. There is a lack of information on participation in research bronchoscopy studies in the literature. A bronchoscopy study has been initiated at Haukeland University Hospital, Bergen, Norway, to examine the role of the microbiome in COPD, and participation will be explored as a substudy.

    Full Text Available A significant reduction in arterial blood oxygen saturation during fiberoptic bronchoscopy has been proved but it is not yet known whether all patients need supplemental oxygen during this procedure. The aim of study is to examine the relationship between peak expiratory flow rate (PEFR before bronchoscopy and oxygen desaturation during bronchoscopy. Measurement of PEFR (% predicted performed before bronchoscopy and arterial O2 desaturation was assessed with a pulse oximeter during bronchoscopy. Study performed in 66 patients with a median age 53 years, who had been referred to our bronchoscopy unit. None of the patients received supplemental oxygen before the procedure. Thirty nine cases (59% had an episode of O2 desaturation during bronchoscopy. Of them 25 cases (38% had sustained O2 desaturation, requiring oxygen therapy while 14 cases (21% had momentary desaturation (< 20s not requiring O2 therapy. Oxygen therapy was administered in 58% of cases with PEFR % < 60 and in 83% of cases with PEFR % less than 45 (P, 0.008 and 0.001, respectively. We also observed a significant fall in mean O2 saturation during bronchoscopy (88 ± 4 % compared to prebronchoscopy levels (95 ± 2 % (P < 0.0001. It is concluded that PEFR < 60% and especially < 45% is a reliable predictor of hypoxemia and the need to O2 therapy during bronchoscopy.

    Bronchoscopy education is undergoing significant changes in step with other medical and surgical specialties that seek to incorporate simulation-based training and objective measurement of procedural skills into training programmes. Low- and high-fidelity simulators are now available and allow learners to gain fundamental bronchoscopy skills in a zero-risk environment. Testing trainees on simulators is currently possible by using validated assessment tools for both essential bronchoscopy and endobronchial ultrasound skills, and more tools are under development for other bronchoscopic techniques. Educational concepts including the 'flipped classroom' model and problem-based learning exercises are increasingly used in bronchoscopy training programmes. These learner-centric teaching modalities require well-trained educators, which is possible thorough the expansion of existing faculty development programmes. PMID:24689877

    Full Text Available Since the introduction of the flexible fibreoptic bronchoscope in the late 1960s there have been relatively few technological advances for three decades, aside from the development of a white light video bronchoscope with a miniature charge-coupled device built in its tip replacing the fibreoptics. White light flexible videobronchoscopy with its ancillary devices (forceps biopsy, bronchial brushing, bronchoalveolar lavage, bronchial washings and transbronchial needle aspiration has long been the only established diagnostic bronchoscopic technique. With the advances in microtechnology over the past two decades, recent technical developments such as autofluorescence bronchoscopy and endoscopic ultrasound allow better evaluation of endobronchial, mediastinal and parenchymal lesions.

    2007-03-01

    The aim of this study was to demonstrate the possibilities, advantages and limitations of virtual bronchoscopy using data sets from positron emission tomography (PET) and computed tomography (CT). Eight consecutive patients with lung cancer underwent PET/CT. PET was performed with F-18-labelled 2-[fluorine-18]-fluoro-2-deoxy-D: -glucose ((18)F-FDG). The tracheobronchial system was segmented with a volume-growing algorithm, using the CT data sets, and visualized with a shaded-surface rendering method. The primary tumours and the lymph node metastases were segmented for virtual CT-bronchoscopy using the CT data set and for virtual PET/CT-bronchoscopy using the PET/CT data set. Virtual CT-bronchoscopy using the low-dose or diagnostic CT facilitates the detection of anatomical/morphological structure changes of the tracheobronchial system. Virtual PET/CT-bronchoscopy was superior to virtual CT-bronchoscopy in the detection of lymph node metastases (P=0.001), because it uses the CT information and the molecular/metabolic information from PET. Virtual PET/CT-bronchoscopy with a transparent colour-coded shaded-surface rendering model is expected to improve the diagnostic accuracy of identification and characterization of malignancies, assessment of tumour staging, differentiation of viable tumour tissue from atelectases and scars, verification of infections, evaluation of therapeutic response and detection of an early stage of recurrence that is not detectable or is misjudged in comparison with virtual CT-bronchoscopy.

    The study illustrates advantages of Fiberoptic Bronchoscopy, a new service started at St. Luke’s General Hospital in patient care since April 2014. Retrospective review of Bronchoscopies and referrals to Tertiary care unit for Bronchoscopy, prior and after initiation of service at St. Luke’s Hospital were studied. In total, 106 procedures were performed out of which 103(98%) were for diagnostic purpose. Common indications for bronchoscopy were functional airway assessment in 38 cases (35%) of chronic cough, 26 cases (24.8%) of suspected malignancy. The average time taken for procedure was 15 + 1 minute with overall rate of complication recorded in 1 case (0.95%). 32(30%) inpatients were referred before bronchoscopy services were started locally. Fifteen (14%) patients were referred for Endobronchial Ultrasound (EBUS) after diagnostic procedure performed at St. Luke’s Hospital. To conclude, Bronchoscopy is a safe procedure used for diagnosis of various Lung conditions. The services offered locally reduced the time and cost involved in referrals. The diagnostic bronchoscopies performed for malignancy at St. Luke’s Hospital have rightly increased references for EBUS at Tertiary care Unit

    2013-04-01

    Ultrathin (UT) bronchoscopy has emerged as a useful tool to diagnose peripheral solid lung lesions of a malignant nature. This technology is superior to standard bronchoscopic techniques, which have low yield in identifying small lesions, especially as they extend further out along the bronchial tree. UT bronchoscopy can prevent the need to pursue more invasive open lung strategies to diagnose suspicious lesions. In this report, we present 3 distinct clinical scenarios where UT bronchoscopy was successful in diagnosing benign peripheral cavitary lesions after standard techniques failed. The use of UT bronchoscopy in each case was instrumental in allowing rapid initiation of appropriate therapy without need for more invasive surgical biopsies in the setting of a benign condition.

    Full Text Available OBJECTIVE: To evaluate the importance of flexible bronchoscopy in tracheostomy patients in the process of decannulation to assess the incidence and types of laryngotracheal injury and compare the presence of such lesions with clinical criteria used for decannulation. METHODS: We studied 51 tracheostomized patients aged between 19 and 87 years, with tracheal stent for a mean of 46 ± 28 days and with clinical criteria for decannulation. They were submitted to tracheostomy tube occlusion tolerance testfor 24 hours, and then to flexible bronchoscopy. We described and classified the diagnosed laryngotracheal changes. We compared the clinical criteria for decannulation indication with the bronchoscopy-diagnosed laryngotracheal injuries that contraindicated decannulation. We identified the factors that could interfere in decannulation and evaluated the importance of bronchoscopy as part of the process. RESULTS: Forty (80.4% patients had laryngotracheal alterations. Of the 40 patients considered clinically fit to decannulation, eight (20% (p = 0.0007 presented with laryngotracheal injuries at bronchoscopy that contraindicated the procedure. The most frequent laryngeal alteration was vocal cords lesion, in 15 (29% individuals, and granuloma, the most prevalent tracheal lesion, in 14 (27.5% patients. CONCLUSION: flexible bronchoscopy showed a large number of laryngotracheal injuries, the most frequent being the vocal cords injury in the larynx and the granuloma in the trachea, which contributed to increase the decannulation procedure safety.

    To evaluate the feasibility of and the potential for using optical coherence tomography in conjunction with conventional bronchoscopy in the evaluation of the airways. Methods: This was a pilot study based on an ex vivo experimental model involving three animals: one adult New Zealand rabbit and two Landrace pigs. An optical coherence tomography imaging catheter was inserted through the working channel of a flexible bronchoscope in order to reach the distal trachea of the animals. Images of the walls of the trachea were systematically taken along its entire length, from the distal to the proximal portion. Results: The imaging catheter was easily adapted to the working channel of the bronchoscope. High-resolution images of cross sections of the trachea were taken in real time, precisely delineating microstructures, such as the epithelium, submucosa, and cartilage, as well as the adventitia of the anterior and lateral tracheal walls. The corresponding layers of the epithelium, mucosa, and cartilage were clearly differentiated. The mucosa, submucosa, and trachealis muscle were clearly identified in the posterior wall. Conclusions: It is feasible to use an optical coherence tomography imaging catheter in combination with a flexible bronchoscope. Optical coherence tomography produces high resolution images that reveal the microanatomy of the trachea, including structures that are typically seen only on images produced by conventional histology.

  16. Hands-Free System for Bronchoscopy Planning and Guidance.

    Khare, Rahul; Bascom, Rebecca; Higgins, William E

    2015-12-01

    Bronchoscopy is a commonly used minimally invasive procedure for lung-cancer staging. In standard practice, however, physicians differ greatly in their levels of performance. To address this concern, image-guided intervention (IGI) systems have been devised to improve procedure success. Current IGI bronchoscopy systems based on virtual bronchoscopic navigation (VBN), however, require involvement from the attending technician. This lessens physician control and hinders the overall acceptance of such systems. We propose a hands-free VBN system for planning and guiding bronchoscopy. The system introduces two major contributions. First, it incorporates a new procedure-planning method that automatically computes airway navigation plans conforming to the physician's bronchoscopy training and manual dexterity. Second, it incorporates a guidance strategy for bronchoscope navigation that enables user-friendly system control via a foot switch, coupled with a novel position-verification mechanism. Phantom studies verified that the system enables smooth operation under physician control, while also enabling faster navigation than an existing technician-assisted VBN system. In a clinical human study, we noted a 97% bronchoscopy navigation success rate, in line with existing VBN systems, and a mean guidance time per diagnostic site = 52 s. This represents a guidance time often nearly 3 min faster per diagnostic site than guidance times reported for other technician-assisted VBN systems. Finally, an ergonomic study further asserts the system's acceptability to the physician and long-term potential.

    Interventional bronchoscopy is a rapidly expanding field in respiratory medicine offering minimally invasive therapeutic and palliative procedures for all types of lung neoplasms. This field has progressed over the last couple of decades with the application of new technology. The HERMES European curriculum recommendations include interventional bronchoscopy skills in the modules of thoracic tumours and bronchoscopy [1]. However, interventional bronchoscopy is not available in all training centres and consequently, not all trainees will obtain experience unless they rotate to centres specifically offering such training. In this review, we give an overview of interventional bronchoscopic procedures used for the treatment and palliation of thoracic malignancy. These can be applied either with flexible or rigid bronchoscopy or a combination of both depending on the anatomical location of the tumour, the complexity of the case, bleeding risk, the operator's expertise and preference as well as local availability. Specialised anaesthetic support and appropriately trained endoscopy staff are essential, allowing a multimodality approach to meet the high complexity of these cases. PMID:26632425

    A 58-year-old man was admitted to our hospital because of fever and loss of appetite. He had undergone surgery for esophageal cancer. A chest radiography 12 years after the surgery revealed cavitary lesions in the right upper lobe of the lung. The patient was then diagnosed as having Mycobacterium avium infection. The cavitary lesions worsened 2 years after clarithromycin monotherapy. Bronchoscopy was performed to observe the interior of the cavity. Gray debris adhering to the cavitary wall decreased after intensive treatment with Streptomycin, rifabutin, levofloxacin, and ethambutol. This is a rare case in which treatment efficacy of M. avium infection was directly observed by serial bronchoscopy. PMID:23207537

    We describe the case of a tension pneumothorax occurring during flexible bronchoscopy in a nonintubated infant. The pneumothorax likely occurred secondary to wall source oxygen insufflation via the bronchoscope without sufficient gas egress. The use of wall source oxygen via the bronchoscope working channel is inherently dangerous and should be avoided. PMID:26740408

    2016-01-01

    Bronchoscopy is considered a stressful procedure performed on patients. Hence, the use of music to ease the anxiety of patients has been examined in various studies, but the results have been inconclusive. The aim of this review is to synthesize the findings of previous studies on the effects of music therapy on the physiological outcomes of patients undergoing bronchoscopy. An electronic database search was performed to identify the literature. Random-effects model was used to combine the results, and meta-regression was used to explore the heterogeneity. Seven studies with 829 subjects were included. Results showed that the combined mean differences (95% confidence interval) for systolic and diastolic blood pressure were -11.99 (-15.82, -6.57) and -4.84 (-7.78, -1.90) mm Hg, respectively, whereas that for heart rate was -10.57 (-16.63, -4.51) beats per minute. In conclusion, listening to music reduced blood pressure and heart rate among patients undergoing bronchoscopy. PMID:26764267

    Foreign body (FB) inhalation in the tracheobronchial tree is an infrequently encountered event in adults. The diagnosis is suspected in the presence of a clinical history of aspiration and the presence of respiratory symptoms. Management involves confirmation by flexible bronchoscopy, which may be both diagnostic as well as therapeutic. However, in certain situations including those with large FB, FB embedded in granulation tissue or FB with very smooth margins, rigid bronchoscopy may be superior to flexible bronchoscopy in the retrieval of the FB. An alternative to rigid bronchoscopy in such situations may be the use of a cryoprobe. Herein, we describe a patient with a large tracheobronchial FB causing a complete collapse of the left lung and hypoxemia. The FB was successfully extracted using a cryoprobe during flexible bronchoscopy, obviating the need for rigid bronchoscopy.

    Full Text Available To evaluate the occurrence of electrocardiographic abnormalities during fiberoptic bronchoscopy, in relation to specific stages of the procedures, patients′ age, sex, smoking, pre-existing lung disease, premedication and oxygen saturation, a prospective study was conducted on 56 patients aged 35 to 75 (mean 62 years without pre-existing cardiovascular disease. Patients were connected to a 12-lead computerized electrocardiographic recorder and pulse oximeter. Fall of oxygen saturation from mean of 95.12% before the procedure to below 80% was observed in 12 (21.4% patients and below 75% in 5 (8.9% patients, at various stages. Statistically highly significant (p < 0.001 fall of oxygen saturation was observed during the procedures while bronchoscope was introduced into the airways and tracheobronchial tree examined. Major disturbances of cardiac rhythm (i.e. atrial, ventricular or both developed in 23 (41.07% patients. Out of these, sinus tachycardia was noted in 16 (69.5%, ventricular premature complexes in 5 (21.7% and paroxysmal supraventricular tachycardia in 2 (8.6% patients. Arrhythmias were most frequent in association with periods of maximum oxygen desaturation in 18 (78.2% of these 23 patients. Oxygen desaturation persisted for more than half an hour in 38 (67.8% of the 56 patients. However, no correlation was observed between the frequency of arrhythmias during bronchoscopy and patients′ age, sex pre-medication or pre-existing pulmonary disease.

    Tracheal or bronchial proximal stenoses occur as complications in 20-30% of lung cancers, resulting in a dramatic alteration in quality of life and poor prognosis. Bronchoscopic management of these obstructions is based on what are known as "thermal" techniques for intraluminal stenosis and/or placement of tracheal or bronchial prostheses for extrinsic compressions, leading to rapid symptom palliation in the vast majority of patients. This invasive treatment should only be used in cases of symptomatic obstructions and in the presence of viable bronchial tree and downstream parenchyma. This review aims to clarify 1) the available methods for assessing the characteristics of stenoses before treatment, 2) the various techniques available including their preferred indications, outcomes and complications, and 3) the integration of interventional bronchoscopy in the multidisciplinary management of proximal bronchial cancers and its synergistic effects with the other specific treatments (surgery, radiotherapy or chemotherapy).

    The diagnostic value of flexible bronchoscopy in the pre-operative work-up of solitary pulmonary nodules (SPN) is still under debate among pneumologists, radiologists and thoracic surgeons. In a prospective observational manner, flexible bronchoscopy was routinely performed in 225 patients with SPN of unknown origin. Of the 225 patients, 80.5% had lung cancer, 7.6% had metastasis of an extrapulmonary primary tumour and 12% had benign aetiology. Unsuspected endobronchial involvement was found in 4.4% of all 225 patients (or in 5.5% of patients with lung cancer). In addition, flexible bronchoscopy clarified the underlying aetiology in 41% of the cases. The bronchoscopic biopsy results from the SPN were positive in 84 (46.5%) patients with lung cancer. Surgery was cancelled due to the results of flexible bronchoscopy in four cases (involvement of the right main bronchus (impaired pulmonary function did not allow pneumonectomy) n=1, small cell lung cancer n=1, bacterial pneumonia n=2), and the surgical strategy had to be modified to bilobectomy in one patient. Flexible bronchoscopy changed the planned surgical approach in five cases substantially. These results suggest that routine flexible bronchoscopy should be included in the regular pre-operative work-up of patients with SPN. PMID:22496316

    Lung cancer is the leading cause of cancer-related mortality worldwide. A low cure rate of lung cancer is not only attributed to intrinsic aggressive biological behavior, but also little attention to lung cancer screening. With lung screening methods continuous progress, peripheral pulmonary lesions detection rate gradually increased. Currently, a transbronchial approach using a bronchoscope or computed tompgraphy (CT) guided transthoracic needle aspiration/biopsy have been the most generally accepted methods for diagnosing peripheral pulmonary lesions. However, conventional bronchoscopy has a poor diagnostic yield and CT-guided approach has high rates of pneumothorax for such peripheral pulmonary lesions. Therefore, clinicians will be challenged with the task of providing the means to provide a safe and minimally invasive method of obtaining accurate tissue diagnostics for the pulmonary peripheral lesions. New bronchoscopic interventional diagnosis technologies have recommended in clinical gradually. They can effectively improve the peripheral pulmonary lesions diagnosis rate, shorten the time of diagnosis, and make the patients get timely and effective treatment. In this paper, we reviewed briefly available technologies to aid clinicians in attempts at minimally invasive techniques. PMID:27561808

    Full Text Available Background and Aim: Rigid bronchoscopy is often an indispensable procedure in the therapeutic management of a wide variety of tracheobronchial disorders. However, it is performed at only a few centers in adult patients in India. Herein, we report our initial 1-year experience with this procedure. Materials and Methods: A prospective observational study on the indications, outcomes, and safety of various rigid bronchoscopy procedures performed between November 2009 and October 2010. Improvement in dyspnea, cough, and the overall quality of life was recorded on a visual analog scale from 0 to 100 mm. A systematic review of PubMed was performed to identify studies reporting the use of rigid bronchoscopy from India. Results: Thirty-eight rigid bronchoscopies (50 procedures were performed in 19 patients during the study period. The commonest indication was benign tracheal stenosis followed by central airway tumor, and the procedures performed were rigid bronchoplasty, tumor debulking, and stent placement. The median procedure duration was 45 (range, 30-65 min. There was significant improvement in quality of life associated with therapeutic rigid bronchoscopy. Minor procedural complications were encountered in 18 bronchoscopies, and there was no procedural mortality. The systematic review identified 15 studies, all on the role of rigid bronchoscopy in foreign body removal. Conclusions: Rigid bronchoscopy is a safe and effective modality for treatment of a variety of tracheobronchial disorders. There is a dire need of rigid bronchoscopy training at teaching hospitals in India.

    Bronchoscopy to examine peripheral pulmonary lesions is performed using a bronchoscope with an outer diameter of 5-6mm under fluoroscopy, but the diagnostic yield can be insufficient. Problems with transbronchial biopsy include a limited range of bronchoscope insertion, difficulty in guiding a bronchoscope and biopsy instruments to lesions, and insufficient confirmation of the arrival of biopsy instruments at the target lesion; as such, new techniques have been used to overcome these individual problems. Radial-endobronchial ultrasound is used to identify peripheral pulmonary lesions and sampling sites. In a meta-analysis, the diagnostic yield, that of lesions smaller than 2cm, and complication rate were 73, 56.3, and 1.0%, respectively. Virtual bronchoscopic navigation is a method to guide a bronchoscope to peripheral lesions under direct vision using virtual bronchoscopic images of the bronchial route, and the diagnostic yield, that of 2-cm or smaller lesions, and complication rate were 73.8, 67.4, and 1.0%, respectively. Electromagnetic navigation utilizes electromagnetism; the diagnostic yield was 64.9-71%, and the pneumothorax complication rate was 4% for this modality. Ultrathin bronchoscopes can be advanced to the peripheral bronchus under direct vision in contrast to normal-size bronchoscopes, and the diagnostic yield and pneumothorax complication rates were reported to be 63 and 1.5%, respectively. The overall diagnostic yield of these new techniques on meta-analysis was 70%, a higher yield than that obtained with conventional transbronchial biopsy. Each technique has advantages and disadvantages, and the investigation of appropriate combinations corresponding to individual cases is necessary. PMID:27424820

  19. Bronchoscopy as a supplement to computed tomography in patients with haemoptysis may be unnecessary

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Background: Haemoptysis is a common symptom and can be an early sign of lung cancer. Careful investigation of patients with haemoptysis may lead to early diagnosis. The strategy for investigation of these patients, however, is still being debated. Objectives: We studied whether the combination of computed tomography (CT and bronchoscopy had a higher sensitivity for malignant and non-malignant causes of haemoptysis than CT alone. Methods: The study was a retrospective, non-randomised, two-centre study and included patients who were referred from primary care for the investigation of haemoptysis. Results: A total of 326 patients were included in the study (mean age 60.5 [SD 15.3] years, 63.3% male. The most common aetiologies of haemoptysis were cryptogenic (52.5%, pneumonia (16.3%, emphysema (8.0%, bronchiectasis (5.8% and lung cancer (4.0%. In patients diagnosed with lung cancer, bronchoscopy, CT and the combination of bronchoscopy and CT had a sensitivity of 0.61, 0.92 (p<0.05 and 0.97 (p=0.58, respectively. In patients with non-malignant causes of haemoptysis, most aetiologies were diagnosed by CT and comprised mainly pneumonia, emphysema and bronchiectasis. Bronchoscopy did not reveal these conditions and the sensitivity to these conditions was not increased by combining CT and bronchoscopy. Conclusions: CT can stand alone as a diagnostic workup for patients with haemoptysis referred to an outpatient clinic. Bronchoscopy does not identify any malignant aetiologies not already diagnosed by CT. Combining the two test modalities does not result in a significant increase in sensitivity for malignant or non-malignant causes of haemoptysis.

    Three patients suffering from severe, chronic, bronchial asthma underwent bronchoscopy and lavage, using in the irrigant fluid acetylcysteine, isoetharine and Solu-Medrol. All patients had a large amount of thick mucus in the tracheobronchial tree which was removed during the lavage. Following the lavage, all three patients were easily treated with conventional allergic measures and were able to lead normal lives, which they could not do before. A discussion of the precautions to be taken by the medical-surgical team in charge of a patient undergoing bronchoscopy and lavage is made. These conclusions were based on the results of two previous reports by the authors in addition to the present communication.

    Full Text Available Background: Because of airway stimulations during the bronchoscopy and lack of direct access to the airway, preferred method of anesthesia for rigid bronchoscopy is already controversial. In this study we compared inhalation anesthesia with total intravenous anesthesia (TIVA for rigid bronchoscopy. Method and Materials: 30 patients aged 2-6 years were chosen divided on two same groups. Anesthesia in group I maintained with halothane and in group II maintained with remifentanil and propofol. Oxygenation, heart rate, respiratory rate, coughing, bucking, laryngospasm, bronchospasm were evaluated during and after surgery. Also Operation success and surgeon’s satisfaction were recorded as well.Results: Demographic findings were the same in both groups. Oxygenation and heart rate were more stable in group II (P=0.047 and P=0.026 respectively but there was no significant difference in respiratory rate between two groups (P=1. Success rate was also similar in both groups but surgeon’s satisfaction was significantly higher in TIVA (P=0.003. There was not any significant different between complications in two groups. Conclusion: We suggest TIVA for rigid bronchoscopy because of better oxygenation, more homodynamic stability, surgeon’s satisfaction, lack of air pollution and less interference with surgeon’s visual field.

    The objective of this study is to investigate the effects of full airway drainage by fiber bronchoscopy through artificial airway in the treatment of traumatic atelectasis with occult manifestations. From May 2006 to May 2011, 40 cases of occult traumatic atelectasis were enrolled into our prospective study. Group A (n = 18) received drainage by nasal bronchoscope; group B underwent airway drainage by fiber bronchoscopy through artificial airway (n = 22). The effects of treatment were evaluated by the incidence of adult respiratory distress syndrome (ARDS), lung abscess, and the average length of hospital stay. Compared with nasal fiber-optic treatment, airway drainage by fiber bronchoscopy through artificial airway reduced the incidence of ARDS (p = 0.013) and lung abscess (p = 0.062) and shortened the mean length of stay (p = 0.018). Making the decision to create an artificial airway timely and carry out lung lavage by fiber bronchoscopy through artificial airway played a significant role in the treatment of occult traumatic atelectasis.

    Flexible bronchoscopy is essential for appropriate care during mechanical ventilation, but can significantly affect mechanical ventilation of the lungs, particularly for patients with acute respiratory distress syndrome. We aimed to describe the consequences of bronchoscopy during lung-protective ventilation in a bench study, and thereby to determine the optimal diameter of the bronchoscope for avoiding disruption of the protective-ventilation strategy during the procedure. Immediately following the insertion of the bronchoscope into the tracheal tube, either minute ventilation decreased significantly, or positive end-expiratory pressure increased substantially, according to the setting of the inspiratory pressure limit. The increase in end-expiratory pressure led to an equivalent increase in the plateau pressure, and lung-protective ventilation was significantly altered during the procedure. We showed that a bronchoscope with an external diameter of 4 mm (or less) would allow safer bronchoscopic interventions in patients with severe acute respiratory distress syndrome. PMID:26559154

    Guided bronchoscopy has been found to be useful for the diagnosis of solid peripheral pulmonary lesions (PPLs) but more evidence on ground glass opacities (GGOs), especially those without a solid component, are lacking. A 69-year-old male, asymptomatic, heavy smoker was referred to our department for non-surgical diagnosis of a focal pure GGO in the right upper lobe that was found incidentally on computed tomography (CT). Transbronchial biopsy (TBB) with the aide of endobronchial ultrasound with a guide sheath (EBUS-GS), virtual bronchoscopic navigation (VBN), and fluoroscopy was performed for sampling. There were no complications after the procedure. The diagnosis of adenocarcinoma with lepidic growth pattern was established from the fourth and fifth TBB specimens and was confirmed on subsequent surgical resection. Image-guided bronchoscopy with TBB was successful for the diagnosis of a pure GGO. Use of a larger biopsy device may be helpful for the histopathologic diagnosis of lung adenocarcinoma with lepidic growth. PMID:24977033

  7. Value of CT-guided fine needle aspiration in solitary pulmonary nodules with negative fiberoptic bronchoscopy

    International Nuclear Information System (INIS)

    The usefulness of fine needle aspiration (FNA) with CT-guidance was evaluated in the diagnosis of solitary pulmonary nodules (SPN) following negative fiberoptic bronchoscopy in 84 patients. The records were analyzed for all patients with SPN who had undergone chest FNA in the years 1988 to 1990, showing previous nondiagnostic fiberoptic bronchoscopy. A final diagnosis was made by biopsy (transbronchial, thoracotomy or necropsy), response to therapy or follow-up of the lesions. The patients had medium-sized lesions, 2.87 ± 1.11 cm, adherent to the pleura in 62%. In the diagnosis of malignancy FNA showed 76% sensitivity, 100% specificity, 100% positive predictive value, 52% negative predictive value and 81% accuracy. These results were correlated with histology in 84% of the cases. One pulmonary hemorrhage, which resolved spontaneously, and 12 cases of pneumothorax, requiring a thoracic tube in 4 patients, were noted. (orig.)

    2005-04-01

    The dependence on macro-optical imaging of the human body in the assessment of possible disease is rapidly increasing concurrent with, and as a direct result of, advancements made in medical imaging technologies. Assessing the pulmonary airways through bronchoscopy is performed extensively in clinical practice however remains highly subjective due to limited visualization techniques and the lack of quantitative analyses. The representation of 3D structures in 2D visualization modes, although providing an insight to the structural content of the scene, may in fact skew the perception of the structural form. We have developed two methods for visualizing the optically derived airway mucosal features whilst preserving the structural scene integrity. Shape from shading (SFS) techniques can be used to extract 3D structural information from 2D optical images. The SFS technique presented addresses many limitations previously encountered in conventional techniques resulting in high-resolution 3D color images. The second method presented to combine both color and structural information relies on combined CT and bronchoscopy imaging modalities. External imaging techniques such as CT provide a means of determining the gross structural anatomy of the pulmonary airways, however lack the important optically derived mucosal color. Virtual bronchoscopy is used to provide a direct link between the CT derived structural anatomy and the macro-optically derived mucosal color. Through utilization of a virtual and true bronchoscopy matching technique we are able to directly extract combined structurally sound 3D color segments of the pulmonary airways. Various pulmonary airway diseases are assessed and the resulting combined color and texture results are presented demonstrating the effectiveness of the presented techniques.

    2010-09-01

    Full Text Available Abstract Background Airway complications are among the most challenging problems after lung transplantation, and Self-Expandable Metallic Stents (SEMS are used to treat airway complications such as stenosis or malacia at the bronchial anastomosis sites. Several transplantation centers are reluctant to use SEMS since their removal is sometimes needed and usually requires the use of rigid bronchoscopy under general anesthesia. The objective of the current report is to describe our experience in SEMS retrieval by flexible bronchoscopy under conscious sedation. Methods A retrospective review was done of patients requiring tracheobronchial stent placement after lung transplantation in which the SEMS had to be removed. The retrieval procedure was done by flexible bronchoscopy on a day-care ambulatory basis. Results Between January 2004 and January 2010, out of 305 lung transplantation patients, 24 (7.8% underwent SEMS placement. Indications included bronchial stenosis in 20 and bronchomalacia in 4. In six patients (25% the SEMS had to be removed due to excessive granulation tissue formation and stent obstruction. The average time from SEMS placement to retrieval was 30 months (range 16-48 months. The stent was completely removed in five patients and partially removed in one patient; no major complications were encountered, and all patients were discharged within 3 hours of the procedure. In all procedures, new SEMS was successfully re-inserted thereafter. Conclusions The retrieval of SEMS in patients that underwent lung transplantation can be effectively and safely done under conscious sedation using flexible bronchoscopy on a day-care basis, this observation should encourage increasing usage of SEMS in highly selected patients.

    Full Text Available The latest American Heart Association (AHA statement for preventing infectious endocarditis, has not recommended prophylactic antibiotic therapy prior to fiberoptic bronchoscopy (FB except for patients with preexisting predisposing cardiac conditions. Our aim was to determine the incidence of bacteriemia and fever following FB in our experience and compare with those which have been mentioned in AHA guideline as well as other studies. Venous blood of 85 consecutive patients was evaluated for both aerobic and anaerobic cultures before (for detecting possible previous bacteriemia and after FB. None of the patients were treated with antibiotics prior to the procedure. All the patients were examined during the first 24 hours after FB for detecting fever defined as temperature more than 38 °C. Positive hemocultures were noted in 7 (8.2 % patients after FB examination. Coagulase negative Staphylococcus, coagulase positive Staphylococcus, beta haemolytic Streptococcus, Citrobacter freundii and Streptococcus viridans were found in 4, 1, 1 and 1 cultures of patients, respectively. By excluding 6 contaminated samples, the rate of bacteriemia reduced to 1 (1.1% patient in whom the identical pathogen (Streptococcus viridans was found both in bronchial lavage and venous blood culture. We also found fever in 9 (10.5 % cases in the first 24 hours following the bronchoscopy. Our results were in consistent with AHA recommendations regarding prevention of infectious endocarditis as a practical gridline in patients who schedule for FB. Besides, transient fever following bronchoscopy is a common self-limited event which does not need medical intervention.

    While classic virtual bronchoscopy offers visualization facilities for investigating the shape of the inner airway wall surface, it provides no information regarding the local thickness of the wall. Such information may be crucial for evaluating the severity of remodeling of the bronchial wall in asthma and to guide bronchial biopsies for staging of lung cancers. This paper develops a new functionality with the virtual bronchoscopy, allowing to estimate and map the information of the bronchus wall thickness on the lumen wall surface, and to display it as coded colors during endoluminal navigation. The local bronchus wall thickness estimation relies on a new automated 3D segmentation approach using strong 3D morphological filtering and model-fitting. Such an approach reconstructs the inner/outer airway wall surfaces from multi-detector CT data as follows. First, the airway lumen is segmented and its surface geometry reconstructed using either a restricted Delaunay or a Marching Cubes based triangulation approach. The lumen mesh is then locally deformed in the surface normal direction under specific force constraints which stabilize the model evolution at the level of the outer bronchus wall surface. The developed segmentation approach was validated with respect to both 3D mathematicallysimulated image phantoms of bronchus-vessel subdivisions and to state-of-the-art cross-section area estimation techniques when applied to clinical data. The investigation in virtual bronchoscopy mode is further enhanced by encoding the local wall thickness at each vertex of the lumen surface mesh and displaying it during navigation, according to a specific color map.

    During a six-month period, 40 consecutive fiberoptic bronchoscopic procedures including bronchoalveolar lavage, bronchial brushing and forceps biopsy were performed in local anaesthesia on 34 HIV-infected males presenting symptoms compatible with Pneumocystis carinii pneumonia. In 23 examinations...... did not differ with regard to history, clinical examination, immunology, serology or chest radiograph. We conclude that fiberoptic bronchoscopy should be performed on wide indications in HIV-infected patients with symptoms compatible with P. carinii pneumonia. The procedure is easily performed, it is...

    Full Text Available Topical airway anesthesia is known to improve tolerance and patient satisfaction during flexible bronchoscopy (FB. Lidocaine is commonly used, delivered as an atomized spray. The current study assesses safety and patient satisfaction for nasal anesthesia of a new atomization device during outpatient bronchoscopy in lung transplant recipients.Using a prospective, non-blinded, cross-over design, patients enrolled between 01-10-2014 and 24-11-2014 received 2% lidocaine using the standard reusable nasal atomizer (CRNA. Those enrolled between 25-11-2014 and 30-01-2015, received a disposable intranasal mucosal atomization device (DIMAD. After each procedure, the treating physician, their assistant and the patient independently rated side-effects and satisfaction, basing their responses on visual analogue scales (VAS. At their next scheduled bronchoscopy during the study period, patients then received the alternative atomizer. Written consent was obtained prior to the first bronchoscopy, and the study approved by the institutional ethics committee.Of the 252 patients enrolled between 01-10-2014 and 30-01-2015, 80 (32% received both atomizers. Physicians reported better efficacy (p = 0.001 and fewer side effects (p< = 0.001 for DIMAD in patients exposed to both procedures. Among patients with one visit, physicians and their assistants reported improved efficacy (p = 0.018, p = 0.002 and fewer side effects (p< = 0.001, p = 0.029 for the disposable atomizer, whereas patients reported no difference in efficacy or side effects (p = 0.72 and p = 0.20. No severe adverse events were noted. The cost of the reusable device was 4.08€ per procedure, compared to 3.70€ for the disposable device.Topical nasal anesthesia via a disposable intranasal mucosal atomization device (DIMAD offers comparable safety and patient comfort, compared to conventional reusable nasal atomizers (CRNA in lung transplant recipients. Procedural costs were reduced by 0.34€ per

    Full Text Available Background. The early diagnosis of malignant and premalignant changes of the bronchial mucosa remains a major challenge during bronchoscopy. Intravital staining techniques are not new. Previous small case series suggested that analysis of the bronchial mucosal surface using chromoendoscopy allows a prediction between neoplastic and nonneoplastic lesions. Objectives. The aim of the present study was to evaluate chromobronchoscopy as a method to identify malignant and premalignant lesions in the central airways in a prospective manner. Methods. In 26 patients we performed chromoendoscopy with 0.1% methylene blue during ongoing flexible white light bronchoscopy. Circumscribed lesions in central airways were further analyzed by biopsies and histopathologic examination. Results. In the majority of cases neither flat nor polypoid lesions in the central airways were stained by methylene blue. In particular, exophytic growth of lung cancer did not show any specific pattern in chromobronchoscopy. However, a specific dye staining was detected in one case where exophytic growth of metastatic colorectal cancer was present in the right upper lobe. In two other cases, a circumscribed staining was noted in unsuspicious mucosa. But histology revealed inflammation only. Conclusions. In contrast to previous studies, the present findings clearly indicate that chromobronchoscopy is not useful for early detection of malignant or premalignant lesions of the central airways.

    The aim of this study was to compare helical CT with fiberoptic bronchoscopy findings to appraise the medium-term results of proximal-airways stenting. Twenty-five patients with 28 endobronchial metallic stents inserted for local advanced malignancy (n=13) or benign diseases (n=12) underwent follow-up CT from 3 days to 50 months (mean 8 months). All studies were obtained using helical CT with subsequent multiplanar reformation and three-dimensional reconstruction including virtual bronchoscopy. The location, shape, and patency of stents and adjacent airway were assessed. The results of CT were compared with the results of fiberoptic bronchoscopy obtained with a mean delay of 2.5 days (SD 9 days) after CT scan. Twelve stents (43%) remained in their original position, patent and without deformity. Sixteen stents were associated with local complications: migration (n=6); external compression with persistent stenosis (n=4); local recurrence of malignancy (n=4); fracture (n=1); and non-congruence between the airway and the stent (n=1). The CT demonstrated all the significant abnormalities demonstrated at fiberoptic bronchoscopy except two moderate stenoses (20%) related to granulomata at the origin of the stent. Ten of 14 stents inserted for benign conditions were without complications as compared with 2 of 14 in malignant conditions (p=0.008). Computed tomography is an accurate noninvasive method for evaluating endobronchial stents. The CT is a useful technique for follow-up of patients who have undergone endobronchial stenting. (orig.)

    Full Text Available Aim: The aim of the study was to compare transcricoid injection with "spray as you go" technique for diagnostic fibreoptic bronchoscopy, to perform the procedure without sedation and to record any complication or side effects. Methods: Sixty patients belonging to the age group 20-70 years, undergoing diagnostic bronchoscopy over a period of 6 months, were randomly selected and divided into two groups alternatively to receive 3 ml of 4% lignocaine by a single transcricoid puncture (group I or 2 ml of 4% lignocaine instilled through the bronchoscope on to the vocal cords and further 1 ml of 2% lignocaine into each main bronchus (group II. Additional dose of lignocaine as required was given in both the groups. All patients were given intramuscular atropine 0.6 mg, 20 min before the procedure. Nebulisation with 3 ml of 4% lignocaine was given to all patients. The time from nasal insertion of the bronchoscope to reach the carina was recorded, and the total dose of lignocaine required in both the groups was calculated and compared. The cough episodes during the procedure, systolic blood pressure, and pulse rate were compared before the procedure and 5 min after the procedure in both the groups. A 0-10 visual analogue scale (VAS was used to assess discomfort 30 min after the procedure. Results: The time to reach carina was more in group II (P<0.02, and cough episodes were also more in group II (P<0.05 than in group I. The vitals before the procedure were comparable in both the groups, but 5 min after the procedure the vitals were more stable in group I than in group II, and the total dose of lignocaine required in group II was more than in group I (P<0.001. However, the VAS score was comparable in both the groups. Conclusion: Transcricoid puncture for diagnostic bronchoscopies without sedation was associated with no complication and discomfort and required lesser dose of local anaesthetic with more stable vitals and good conditions for bronchoscopists.

    Twelve healthy approximately 3-yr-old captive-born 4.5-9 kg American alligators (Alligator mississipiensis) each had bronchoscopy and tracheal washes performed four times during a 10-mo period to evaluate seasonal respiratory microbiology and cytology. Cytologic evaluation of most samples showed a small amount of mucus and low numbers of ciliated columnar epithelium, cubodial epithelium, and keratinized squamous cells. No bacteria or parasites were observed, and there was no seasonal variation in the cytology. No significant bacterial or fungal growth was identified in any season. Hematology performed in the spring and fall evaluations showed seasonal variation in the red blood cell count, hemoglobin concentration, mean corpuscular volume, mean corpuscular hemoglobin concentration, eosinophil count, and thrombocyte count. The lower respiratory tract (at the tracheal level) of healthy subadult alligators appears to be sterile, and cytology is similar to that described in domestic mammals. PMID:17315452

    Expression of three major resistance genes MDR1, MRP1 and LRP was investigated in small cell lung cancer, non-small cell lung cancer and metastasis. Single biopsies of bronchoscopy from 73 patients were performed to investigate expression of these three resistance genes by reverse transcriptase-polymerase chain reaction. Relations between gene expression and patient age, smoking status, histology, and chemotherapy were evaluated. A more frequent expression of MDR1 (77 versus 66%), MRP1 (91 versus 72%) and LRP (77 versus 63%) genes was detected in the malignant biopsies than in the non-malignant, respectively. In the metastasis biopsies, expression of these genes was markedly increased. No significant difference was observed between specimens before and after chemotherapy. Biopsies from progressing cancer showed higher MDR1, MRP1 and LRP gene expression. In conclusion, these data reveal a major role of MRP1 in intrinsic resistance and the high gene expression of MDR1 and MRP1 in relapsed diseases.

  5. Bronchoscopy-derived correlates of lung injury following inhalational injuries: a prospective observational study.

    Directory of Open Access Journals (Sweden)

    Samuel W Jones

    Full Text Available BACKGROUND: Acute lung injury (ALI is a major factor determining morbidity following burns and inhalational injury. In experimental models, factors potentially contributing to ALI risk include inhalation of toxins directly causing cell damage; inflammation; and infection. However, few studies have been done in humans. METHODS: We carried out a prospective observational study of patients admitted to the NC Jaycees Burn Center who were intubated and on mechanical ventilation for burns and suspected inhalational injury. Subjects were enrolled over an 8-month period and followed till discharge or death. Serial bronchial washings from clinically-indicated bronchoscopies were collected and analyzed for markers of cell injury and inflammation. These markers were compared with clinical markers of ALI. RESULTS: Forty-three consecutive patients were studied, with a spectrum of burn and inhalation injury severity. Visible soot at initial bronchoscopy and gram negative bacteria in the lower respiratory tract were associated with ALI in univariate analyses. Subsequent multivariate analysis also controlled for % body surface area burns, infection, and inhalation severity. Elevated IL-10 and reduced IL-12p70 in bronchial washings were statistically significantly associated with ALI. CONCLUSIONS: Independently of several factors including initial inhalational injury severity, infection, and extent of surface burns, high early levels of IL-10 and low levels of IL-12p70 in the central airways are associated with ALI in patients intubated after acute burn/inhalation injury. Lower airway secretions can be collected serially in critically ill burn/inhalation injury patients and may yield important clues to specific pathophysiologic pathways.

  6. Clinical value of virtual bronchoscopy in early diagnosis of central malignant lung neoplasm in high risk patients

    International Nuclear Information System (INIS)

    Virtual bronchoscopy (CT-VB) is a recently developed 3D visualization technique that employs thin-section spiral computed tomographic data of the thorax for non-invasive evaluation of the tracheo-bronchial tree. The purpose of this study was to compare the efficacy of multislice-CT virtual bronchoscopy in detecting early endobronchial manifestation of central lung cancer with that of flexible fiberoptic bronchoscopy. For this purpose, a group of 50 high risk patients (cigarette pack-years, long standing history of COLD) underwent both FOB and CT-VB investigation. Multislice CT was performed using the following parameters: collimation, 1 mm; pitch factor, 0.937-1.375; reconstruction interval, 0.8 mm and postprocessing was based on volume rendering technique. Images of eight standard tracheo-bronchial sections were obtained from each patient both during FOB and CT-VB and were independently interpreted respectively by a pneumologist and a bronchiseptica. Airway evaluation was based on the analysis of changes in the mucosal architecture, the shape of the ostia and of the carinae and on the presence of secretion deposits as early signs of tumor onset. The sensitivity of virtual bronchoscopy in discriminating diseased from healthy patients was 94 % and its specificity 65 %. Its positive predictive value 56 % and its negative predictive value 96 %. According to the ROC analysis, except for the assessment of the secretion deposits, the other three criteria evaluated separately during virtual bronchoscopic assessment of the airways contributed equally in discriminating diseased from disease-free patients (areas under curve ranging between 0,797 and 0,845). The best AUC was associated with the evaluation of the sum of all three parameters together (0,858). Nevertheless, FOB and CT-VB results in the evaluation of the shape of the ostia resulted to agree moderately while just a fair agreement was observed with respect to the evaluation of the mucosal architecture and of the

    Pulmonary endarterectomy (PEA) is the treatment of choice to relieve pulmonary artery obstruction in patients with chronic thromboembolic pulmonary hypertension (CTEPH). We present a patient with airway obstruction and acute respiratory failure due to large blood clots obstructing the trachea and main left bronchus. This condition was accompanied by right ventricle failure and cardiogenic shock. A venoarterial ECMO system was used for cardiopulmonary support before extracting the clots and clearing the airway by rigid bronchoscopy. PMID:27229321

    Endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) had an enormous impact on the current advancement in diagnostic bronchoscopy. The aims of the present study were: (1) to evaluate the added value of EBUS-TBNA to routine diagnostic bronchoscopy performed in patients with mediastinal lymph node enlargement and (2) to identify factors that affect the diagnostic yield of EBUS-TBNA. We retrospectively analyzed 712 EBUS-TBNA procedures out of the 4081 bronchoscopies performed in the years 2009-2014. The number of EBUS-TBNA procedures increased from 61 (8.8 % of all bronchoscopies) in 2009 to 160 (21.4 %) in 2014. In 625 (87.8 %) patients adequate cytological material was obtained. Based on cytological examination of EBUS-TBNA aspirates, specific diagnosis was made in 367 (51.5 %) patients. The forceps biopsy of endobronchial lesions provided specific diagnosis in only 204 (28.6 %) patients. The percentage of patients with EBUS-TBNA based diagnosis increased steadily from 34.4 % in 2009 to 65.0 % in 2014 (p lymph node diameter in patients with positive EBUS-TBNA findings was 20 (IQR 15-30) mm and was significantly larger than that in patients with negative EBUS-TBNA results (15 (IQR 10-20) mm, p = 0.0001). The highest diagnostic yield (78.5 %) was found in patients with lymph node dimension between 31 mm and 40 mm. We conclude that EBUS-TBNA is a valuable diagnostic method in an unselected group of patients with mediastinal lymph node enlargement. The percentage of positive EBUS-TBNA diagnoses is related to lymph node dimensions. The overall efficacy of EBUS-TBNA improves with increasing years of experience. PMID:26987324

    Twenty-four consecutive patients scheduled for fiberbronchoscopy were randomized to receive double-blind either intravenous (1.5 mg/kg) or laryngotracheal (3 mg/kg) lidocaine to evaluate the influence on post-bronchoscopic laryngospasm, pain in the throat and coughing. Plasma lidocaine concentrations were analyzed 5, 15, 30 and 60 min after administration. None of the patients demonstrated laryngospasm or pain in the throat during the first hour after bronchoscopy. Patients receiving topical lidocaine coughed significantly more than patients receiving intravenous lidocaine, with a median number of coughs of 20 compared to 4, during the first hour (P less than 0.01). The plasma lidocaine concentrations were significantly higher after intravenous than after topical administration (P less than 0.001). After intravenous administration the plasma lidocaine concentrations exceeded the accepted level for potential toxicity in five out of 11 patients, but none of the patients developed toxic symptoms and no side-effects were observed.

    The porcine model has contributed significantly to biomedical research over many decades. The similar size and anatomy of pig and human organs make this model particularly beneficial for translational research in areas such as medical device development, therapeutics and xenotransplantation. In recent years, a major limitation with the porcine model was overcome with the successful generation of gene-targeted pigs and the publication of the pig genome. As a result, the role of this model is likely to become even more important. For the respiratory medicine field, the similarities between pig and human lungs give the porcine model particular potential for advancing translational medicine. An increasing number of lung conditions are being studied and modeled in the pig. Genetically modified porcine models of cystic fibrosis have been generated that, unlike mouse models, develop lung disease similar to human cystic fibrosis. However, the scientific literature relating specifically to porcine lung anatomy and airway histology is limited and is largely restricted to veterinary literature and textbooks. Furthermore, methods for in vivo lung procedures in the pig are rarely described. The aims of this review are to collate the disparate literature on porcine lung anatomy, histology, and microbiology; to provide a comparison with the human lung; and to describe appropriate bronchoscopy procedures for the pig lungs to aid clinical researchers working in the area of translational respiratory medicine using the porcine model.

    Full Text Available Background: There are no data regarding the factors influencing the choice of therapeutic bronchoscopic modality in the management of malignant airway stenoses. Objectives: To assess the choice of therapeutic bronchoscopy modality and analyze factors influencing survival in patients with malignant central airway obstruction. Materials and Methods: We performed 167 procedures in 130 consecutive patients, for malignant central airway obstruction, over six years. Results: Laser was used either alone or in combination with stent insertion in 76% procedures. Laser only was used in 53% procedures for lesions below the main bronchi. Stents alone were used for extrinsic compression or stump insufficiency. Combined laser and stent insertion was most frequently used for lesions involving the trachea plus both main bronchi or only the main bronchi. The Dumon stent was preferred in lesions of the trachea and the right bronchial tree, the Ultraflex stent for lesions on the left side and stenoses below the main bronchi. Survival was better in patients with lung cancer, lesions restricted to one lung and when laser alone was used compared to esophageal cancer, metastases and tracheal involvement. Conclusion: The choice of different airway stents can be made based on the nature and site of the lesion. Dumon stents are suited for lesions in trachea and right main bronchus and the Ultraflex stents on the left side and stenoses beyond the main bronchi. Survival can be estimated based on the diagnosis, site of the lesion and treatment modality used.

    Full Text Available Background: The importance of rapid and accurate cytopathological diagnosis in bronchial cancers is increasing due to advances in treatment modalities.Aims: We evaluated the diagnostic methods and cytologic subtypes of bronchial cancers to determine the diagnostic reliability of different bronchoscopic techniques.Material and methods: Retrospective data were obtained from the hospital files and pathological specimens of the patients with diagnosis of primary lung cancer from a period of 36 months. Cytological tumor typing was determined using histopathology of bronchoscopic forceps biopsy (FB, bronchial-bronchoalveolar lavage (BL, bronchial brushing (BB, transbronchial fine-needle biopsy. Computed tomography or ultrasonography guided transthoracic biopsy and surgical biopsies were used where the other interventional methods were inadequate for diagnosis.Results: A total of 124 patients were diagnosed during study period. 119 (96% of them were male. The median age was 68, ranging between 36 and 88 years. Histopathologic subtypes were determined as non-small cell carcinoma (NSCC in 104 (83.9%, squamous cell carcinoma in 64 (51.6%, adenocarcinoma in 16 (12.9%, NSCC not otherwise specified in 24 (19.3% and small cell carcinoma in 20 (16.1% patients. The combination of FB, BL and BB established the diagnosis of bronchogenic carcinoma in most of the cases (92.6%.Conclusions: Lung cancer is seen commonly in elderly male patients with smoking history and squamous cell carcinoma is the most common cytologic type. High diagnostic accuracy can be achieved by a combination of bronchoscopic FB, BB and BL procedures. Keywords: Bronchoscopy; Lung cancer; Bronchial brushing

    Yu-Lun Lo

    Full Text Available OBJECTIVES: There are safety issues associated with propofol use for flexible bronchoscopy (FB. The bispectral index (BIS correlates well with the level of consciousness. The aim of this study was to show that BIS-guided propofol infusion is safe and may provide better sedation, benefiting the patients and bronchoscopists. METHODS: After administering alfentanil bolus, 500 patients were randomized to either propofol infusion titrated to a BIS level of 65-75 (study group or incremental midazolam bolus based on clinical judgment to achieve moderate sedation. The primary endpoint was safety, while the secondary endpoints were recovery time, patient tolerance, and cooperation. RESULTS: The proportion of patients with hypoxemia or hypotensive events were not different in the 2 groups (study vs. control groups: 39.9% vs. 35.7%, p = 0.340; 7.4% vs. 4.4%, p = 0.159, respectively. The mean lowest blood pressure was lower in the study group. Logistic regression revealed male gender, higher American Society of Anesthesiologists physical status, and electrocautery were associated with hypoxemia, whereas lower propofol dose for induction was associated with hypotension in the study group. The study group had better global tolerance (p<0.001, less procedural interference by movement or cough (13.6% vs. 36.1%, p<0.001; 30.0% vs. 44.2%, p = 0.001, respectively, and shorter time to orientation and ambulation (11.7±10.2 min vs. 29.7±26.8 min, p<0.001; 30.0±18.2 min vs. 55.7±40.6 min, p<0.001, respectively compared to the control group. CONCLUSIONS: BIS-guided propofol infusion combined with alfentanil for FB sedation provides excellent patient tolerance, with fast recovery and less procedure interference.

  14. Flexible bronchoscopy during non-invasive positive pressure mechanical ventilation: are two better than one?

    Scala, Raffaele

    2016-09-01

    Flexible bronchoscopy (FBO) and non-invasive positive pressure ventilation (NIPPV) are largely applied in respiratory and general intensive care units. FBO plays a crucial role for the diagnosis of lung infiltrates of unknown origin and for the treatment of airways obstruction due to bronchial mucous plugging and hemoptysis in critical patients. NIPPV is the first-choice ventilatory strategy for acute respiratory failure (ARF) of different causes as it could be used as prevention or as alternative to the conventional mechanical ventilation (CMV) via endotracheal intubation (ETI). Some clinical scenarios represent contraindications for these techniques such as severe ARF in spontaneous breathing patients for FBO and accumulated tracheo-bronchial secretions in patients with depressed cough for NIPPV. In these contexts, the decision of performing ETI should carefully consider the risk of CMV-correlated complications. An increasing amount of published data suggested the use of FBO during NIPPV in ARF in order to avoid/reduce the need of ETI. Despite a strong rationale for the combined use of the two techniques, there is not still enough evidence for a large-scale application of this strategy in all different clinical scenarios. The majority of the available data are in favor of the "help" given by NIPPV to diagnostic FBO in high-risk spontaneously breathing patients with severe hypoxemia. Preliminary findings report the successful "help" given by early FBO to NIPPV in patients with hypoxemic-hypercapnic ARF who are likely to fail because of hypersecretion. Synergy of FBO and NIPPV application is emerging also to perform ETI in challenging situations, such as predicted difficult laringoscopy and NPPV failure in severely hypoxemic patients. This combined approach should be performed only in centers showing a wide experience with both NIPPV and FBO, where close monitoring and ETI facilities are promptly available. PMID:27012292

    Full Text Available There are no accurate data on the diagnostic value of preoperative flexible bronchoscopy (FB for persistent ground-glass nodule (GGN of the lung. We evaluated the value of preoperative FB in patients with suspected GGN-type lung cancer. We retrospectively searched a database for subjects who had 'ground-glass opacity', 'non-solid nodule', 'part-solid nodule', or 'sub-solid nodule' on chest computed tomography reports between February 2004 and March 2012. Patients who had infiltrative ground-glass opacity lesions, mediastinal lymphadenopathy, or pleural effusion, focal ground-glass opacity lesions >3 cm, and were lost to follow-up were excluded. We assessed the diagnostic value of preoperative FB in patients with persistent GGNs who underwent surgical resection. In total, 296 GGNs were evaluated by FB in 264 patients with persistent GGNs who underwent preoperative FB and surgical resection. The median size of the GGNs was 18 mm; 135 (46% were pure GGN and 161 (54% were part-solid GGN. No visible tumor or unsuspected endobronchial metastasis was identified by preoperative FB. Only 3 (1%, 3/208 GGNs were identified preoperatively as malignant by bronchial washing cytology; all were part-solid GGNs. No other etiology was identified by FB. Of the GGNs, 271 (91% were subsequently confirmed as malignant and 25 (9% were confirmed as benign at surgical resection. Consequently, the overall diagnostic sensitivity and negative predictive value of preoperative FB on a per-nodule basis was 1% (3/271 and 8% (25/293, respectively. The preoperative FB did not change the surgical strategy. Preoperative FB did not add much to the evaluation of persistent GGNs of the lung. Routine preoperative FB may have limited value in surgical candidates with small persistent pure GGNs.

    The aim of the present study was to assess fibred confocal fluorescence microscopy (FCFM) as a tool for imaging the alveolar respiratory system in vivo during bronchoscopy. A 488-nm excitation wavelength FCFM device was used in 41 healthy subjects including 17 active smokers. After topical anaesthesia, the 1.4-mm miniprobe was introduced into the bronchoscope working channel and advanced distally to the alveoli. Morphometric and cellular analyses were performed on selected frames harbouring a minimal compression effect. In vivo acinar microimaging was obtained from each lung segment except for the apical and posterior segments of both upper lobes. Reproducible patterns, corresponding to the elastic framework of the axial and peripheral interstitial systems, were recorded from 192 separate acini. The mean+/-sd thickness of the acinar elastic fibres was 10+/-2.7 microm. Alveolar mouth diameters (mean+/-sd 278+/-53 microm) were normally distributed but appeared smaller in the right upper lobe and right medial basal segment. Lobular microvessels (median diameter 90 microm) were equally distributed throughout the lungs. Alveolar macrophages were not detectable in nonsmokers, whereas a specific tobacco-tar-induced fluorescence was observed in smoking subjects, providing fine details of the alveolar walls and macrophages. A strong correlation was found between the number of cigarettes smoked per day and the amount of large and mobile macrophages observed in vivo, as well as with the intensity of the macrophage alveolitis. Fibred confocal fluorescence microscopy enables accurate exploration of the peripheral lung in vivo in both smokers and nonsmokers. PMID:19213792

    Full Text Available Aims: To evaluate the diagnostic utility of virtual bronchoscopy, multiplanar reformatted images, and minimal-intensity projection in assessing airway stenoses. Settings and Design: It was a prospective study involving 150 patients with symptoms of major airway disease. Materials and Methods: Fifty-six patients were selected for analysis based on the detection of major airway lesions on fiber-optic bronchoscopy (FB or routine axial images. Comparisons were made between axial images, virtual bronchoscopy (VB, minimal-intensity projection (minIP, and multiplanar reformatted (MPR images using FB as the gold standard. Lesions were evaluated in terms of degree of airway narrowing, distance from carina, length of the narrowed segment and visualization of airway distal to the lesion. Results: MPR images had the highest degree of agreement with FB (Κ = 0.76 in the depiction of degree of narrowing. minIP had the least degree of agreement with FB (Κ = 0.51 in this regard. The distal visualization was best on MPR images (84.2%, followed by axial images (80.7%, whereas FB could visualize the lesions only in 45.4% of the cases. VB had the best agreement with FB in assessing the segment length (Κ = 0.62. Overall there were no statistically significant differences in the measurement of the distance from the carina in the axial, minIP, and MPR images. MPR images had the highest overall degree of confidence, namely, 70.17% (n = 40. Conclusion: Three-dimensional reconstruction techniques were found to improve lesion evaluation compared with axial images alone. The technique of MPR images was the most useful for lesion evaluation and provided additional information useful for surgical and airway interventions in tracheobronchial stenosis. minIP was useful in the overall depiction of airway anatomy.

  18. Cost-effectiveness of CT thorax and bronchoscopy in haemoptysis with normal CXR for exclusion of lung cancer

    International Nuclear Information System (INIS)

    As fibre-optic bronchoscopy and CT thorax become more widely used, patients with haemoptysis who had normal chest x-ray radiography (CXR) and sputum results are more commonly offered both CT and bronchoscopy to exclude lung cancer. Doctors who are under possible litigation pressure arising from missed diagnoses of lung cancer are often exhaustive in their investigations, even when the haemoptysis has been transient. The present study aims to investigate the number of cancer patients who can be detected with the two investigations, and compare recent similar study results with archive results. We found that despite the use of more efficient investigation tools, the yield is paradoxically much lower and, hence, less cost-effective than that of previous studies. The likely reason is that doctors tend to over-investigate, even for short-term, minimal blood-streaked sputum, which is common among simple bronchitis. In order to be more cost-effective, these investigations should be used more selectively and for high risk patients such as those with prolonged haemoptysis and those who are heavy smokers.

    Extracorporeal membrane oxygenation (ECMO) has been used to provide "lung rest" through the use of low tidal volume (6 ml/kg) and ultralow tidal volume (respiratory distress syndrome (ARDS). Low and ultralow tidal volume ventilation can result in low dynamic respiratory compliance and potentially increased retention of airway secretions. We present our experience using automated rotational percussion beds (ARPBs) and bronchoscopy in four ARDS patients to manage increased pulmonary secretions. These beds performed automated side-to-side tilt maneuver and intermittent chest wall percussion. Their use resulted in substantial reduction in peak and plateau pressures in two patients on volume control ventilation, while the driving pressures (inspiratory pressure) to attain the desired tidal volumes in patients on pressure control ventilation also decreased. In addition, mean partial pressure of oxygen in arterial blood (PaO2)/fraction of inspired oxygen (FiO2) ratio (109 pre-ARPB vs. 157 post-ARPB), positive end-expiratory pressure (10 cm H2O vs. 8 cm H2O), and FiO2 (0.88 vs. 0.52) improved after initiation of ARPB. The improvements in the respiratory mechanics and oxygenation helped us to initiate early ECMO weaning. Based on our experience, the use of chest physiotherapy, frequent body repositioning, and bronchoscopy may be helpful in the management of pulmonary secretions in patients supported with ECMO.

    It is not so common to aspirate foreign body in normal adults without any predisposing factors as compared to children and those with the altered neurological state. Endobronchial foreign bodies are one of the causes of obstructive pneumonia and difficult to diagnose as signs and symptoms are often nonspecific. However, once they are diagnosed, they can generally be removed, leading to rapid and drastic resolution of symptoms. Bronchoscopy is the gold standard in the identification and localization of an airway foreign body and also for better management of the ailment. However with the help of virtual bronchoscopy one can decide the location of the foreign body before any invasive intervention and being noninvasive it can be performed in follow-up easily to check the patency of airways. It is not possible to detect the exact size of foreign body with the virtual bronchoscopy. In this article, we report a case of unnoticed foreign body aspiration in a 49-year-old female patient who was initially treated for pneumonia. However, due to nonresolution of opacity contrast enhanced computed tomography thorax with virtual and flexible bronchoscopy were performed, which revealed a foreign body in the right lower lobe bronchus that was removed with biopsy forceps in piecemeal. In her follow-up visit, she underwent virtual broncoscopy that revealed clear airways. Thus, detailed history and high index of suspicion is required for nonresolving pneumonias that may occur due to unnoticed foreign body/ies in an adult. PMID:27578936

    Objective The Bronchoscopy Unit of General Hospital of Lamia provides the necessity of six counties in Thessalia and Central Greece. The first bronchoscopy was performed during Christmas of 2012 while from the opening (February 14th, 2014), the unit is presenting an increasing activity (in number and variety of medical practice). Methods From December 21st in 2012 to September 15th in 2014, were performed 158 bronchoscopic examinations in 152 patients (hospitalized and outpatients), 130 men and 28 women, with an average age 72.4 (29 to 89) years old. There were accomplished 80 biopsies (bronchial, transbronchial), 83 brushing, collected 57 cultures for common bacteria and 86 for och-bacilli (acid-fast microscopy in 12), 20 conventional transbronchial needle aspiration (TBNA), two transbronchial biopsies, seven BAL, 25 bronchial toilets in elderly patients and were removed two foreign bodies (one bone segment surrounding by granulomatous tissue and one segment of animal bowel-“kokoretsi”). Results We observed gradual increase of the incoming patients [Quarterly: 5(1st-3rd/2013), 14(4th-6th/2013), 17(7th-9th/2013), 21(10th-12th/2013), 32(1st-3rd/2014), 38(4th-6th/2014), 31(6th-Middle 9th/2014)]. There were diagnosed 70 cases of lung cancer in 93 patients (75.3%) {12 small cell lung carcinoma (SCLC), 57 non-small cell lung carcinoma (NSCLC) [28 squamous, 25 adenocarcinomas, one combo (adeno- and squamous carcinoma), one BAC και two suspicious samples for cancer]}. 49/49 were diagnosed in evident endobronchial lesion (100%) and 21/44 in non-revealing bronchoscopy (47.8%). Biopsy confirmed diagnosis in 52/93, brushing in 31/93, ΤΒΝΑ alone in 4/8 while washing alone in 3/93 patients. Five cases of active tuberculosis were diagnosed (4 M. Τuberculosis, 1 M.

    Compression of the airway is relatively common in pediatric patients, although it is often an unrecognized complication of congenital cardiac and aortic arch anomalies. Aortopexy has been established as a surgical treatment for tracheobronchial obstruction associated with vascular anomaly, aortic arch anomaly, esophageal atresia, and tracheoesophageal fistula. The tissue-to-tissue arch repair technique could result in severe airway complication such as compression of the left main bronchus which was not a problem before the correction. We report three cases of corrective open heart surgery monitored by intraoperative bronchoscopy performed during prebypass, and performed immediately before weaning from bypass, to evaluate tracheobronchial obstruction caused by congenital, complex cardiac anomalies in the operating room.

    Aim: Latent tuberculosis infections (LTBI) contain a significant reservoir for future epidemics. Screening of health care workers (HCWs) in a high-risk tuberculosis (TB) environment is an important strategy in TB control. The study aimed to assess the prevalence of LTBI among high risk Egyptian HCWs and to assess infection associated risk factors. Methods: Fifty-two HCWs who work at intensive care unit (ICU), bronchoscopy unit, and chest diseases department were tested for LTBI using both tuberculin skin test (TST) and Quantiferon TB Gold in-tube test (QFT). Risk factors for infection, knowledge of HCWs towards different aspects of TB infection and agreement between TST and QFT were also evaluated. Results: Prevalence of LTBI in this study was 13.5% by QFT and TST. It was 13.6% by TST alone and 10.3% by QFT alone. There was good concordance between both tests (Kappa=0.713). There was a statistically significant association between prevalence of LTBI and age of staff ≥30 yr (p=0.002), period of working experience (p=0.006) and working at the Bronchoscopy Unit (p=0.001). The total knowledge of HCWs towards different aspects of TB infection was generally good. Conclusion: Although the participants in the current study were among high risk HCWs, the prevalence of LTBI was low. Bacille Calmette-Guerin (BCG) vaccination, young age, short employment duration, good knowledge and a good infection control were the predictors of low risk of contracting TB at our hospitals. The risk of TB infection in resource-limited countries can be reduced with simple continuous educational and administrative infection control programmes. PMID:27777875

    Foreign body aspiration is common in children, especially those under 3 years of age. Chest radiography and CT are the main imaging modalities for the evaluation of these children. Management of children with suspected foreign body aspiration (SFBA) mainly depends on radiological findings. To investigate the potential use of low-dose multidetector CT (MDCT) and virtual bronchoscopy (VB) in the evaluation and management of SFBA in children. Included in the study were 37 children (17 girls, 20 boys; age 4 months to 10 years, mean 32 months) with SFBA. Chest radiographs were obtained prior to MDCT in all patients. MDCT was performed using a low-dose technique. VB images were obtained in the same session. Conventional bronchoscopy (CB) was performed within 24 h on patients in whom an obstructive abnormality had been found by MDCT and VB. Obstructive pathology was found in 16 (43.25%) of the 37 patients using MDCT and VB. In 13 of these patients, foreign bodies were detected and removed via CB. The foreign bodies were located in the right main bronchus (n = 5), in the bronchus intermedius (n = 6), in the medial segment of the middle lobe bronchus (n = 1), and in the left main bronchus (n = 1). In the remaining three patients, the diagnosis was false-positive for an obstructive pathology by MDCT and VB; the final diagnoses were secretions (n = 2) and schwannoma (n = 1), as demonstrated by CB. In 21 patients in whom no obstructive pathology was detected by MDCT and VB, CB was not performed. These patients were followed for 5-20 months without any recurrent obstructive symptomatology. Low-dose MDCT and VB are non-invasive radiological modalities that can be used easily in the investigation of SFBA in children. MDCT and VB provide the exact location of the obstructive pathology prior to CB. If obstructive pathology is depicted with MDCT and VB, CB should be performed either for confirmation of the diagnosis or for the diagnosis of an alternative cause for the obstruction

    Introduction Inefficient clearance of copious respiratory secretion is a cause of non-invasive positive pressure ventilation (NPPV) failure, especially in chronic respiratory patients with community-acquired-pneumonia (CAP) and impaired consciousness. We postulated that in such a clinical scenario, when intubation and conventional mechanical ventilation (CMV) are strongly recommended, the suction of secretions with fiberoptic bronchoscopy (FBO) may increase the chance of NPPV success.

    Full Text Available Spindle cell (sarcomatoid carcinoma is a rare variant of squamous cell carcinoma (SCC. It compromises of 2–3% of laryngeal cancers. Tumor arises from the oral cavity, tonsil larynx, and pharynx. Tumor is majority times misdiagnosed as reactive lesions or mesenchymal malignancies. It is considered to be a biphasic tumor that is composed of an SCC (in situ or invasive and spindle cell carcinoma (SpCC with sarcomatous appearance. In this case report, 61-year-male with minimal throat pain and acute onset dysphonia misdiagnosed and treated as a case of bronchial asthma with gastroesophageal reflux confirmed to have exophytic laryngeal growth is the cause for clinical presentation. We performed fiberoptic laryngoscopy and diagnosed to have SpCC of larynx. High index of suspicion is a must in geriatric cases with documented history of smoking and fiberoptic laryngoscopy/bronchoscopy found to be crucial in the evaluation. Histopathology expertise in surgical oncology is essential while planning treatment.

    Background: Fiberoptic bronchoscopy (FOB) may exaggerate symptoms and lung functions in patients with pre-existing airway obstruction. Interventions which can alleviate or minimize this procedure-related bronchospasm, especially in this high-risk group are, therefore, required. Methods: A double-blinded randomized controlled trial was conducted to evaluate the efficacy of 400 μg of inhaled salbutamol on patients with spirometric evidence of airflow obstruction planned for FOB. Patient's dyspnea, procedure tolerability, and change in spirometry were assessed before and after the procedure. Results: A total of 50 patients were enrolled (78% males), with a mean (standard deviation) age of 49.8 (6.2) years. There was a significant fall in % predicted FEV1 within each group compared to their respective pre-bronchoscopy values. However, no significant difference in the % predicted or absolute FEV1 level was observed between the two groups. Similarly, although both groups experienced increased dyspnea immediately following FOB, this difference was not significant between the two groups either on the Borg or visual analog scale scales. Pre-FOB anxiety levels and the tolerability of the procedure as assessed by the bronchoscopist were similar in both groups. Conclusion: FOB in patients with pre-existing airway obstruction aggravates cough and dyspnea, with a concomitant decline in FEV1 and FVC. The administration of pre-FOB inhaled salbutamol does not have any significant beneficial effect on procedure-related outcomes.

    Full Text Available Objective: Fiberoptic bronchoscopy (FOB is the most frequently used tool for invasive pulmonary evaluation with high diagnostic yield and low incidence of major complications. These advantages led to increasing use of FOB in intensive care units. In this article, we discussed our experiences of FOB applications in mechanical ventilated critically ill patients. Materials and Methods: We investigated FOB procedures of 118 patients on mechanical ventilation for respiratory failure in intensive care unit retrospectively. All patients’ demographic data, indications, complications and arterial blood gas analyses belong to before and after bronchoscopy were evaluated. Results: FOB indications of the patients were 55.1% for mucoid plug clearance, 9.3% for treatment of atelectasia, 7.6% for identifying hemorrhagic foci, 17.8% for tracheostomy management, 6.8% for bronchoalveolar lavage and 3.4% for exploratory purposes. Overall complication rate of FOB was 11.9%. Arterial blood gas analyses statistically improved after FOB. Conclusion: In this study, we observed that FOB is being performed with many different indications and acceptable complication rates in our intensive care unit and also contributes to diagnose and treatment of intensive care patients.

This pilot study aims to evaluate the feasibility and optimal TCI regimen for flexible bronchoscopy (FB sedation.After alfentanil bolus, initial induction Ce of propofol was targeted at 2 μg/ml. Patients were randomized into three titration groups (i.e., by 0.5, 0.2 and 0.1 μg/ml, respectively to maintain stable sedation levels and vital signs. Adverse events, frequency of adjustments, drug doses, and induction and recovery times were recorded.The study was closed early due to significantly severe hypoxemia events (oxyhemoglobin saturation <70% in the group titrated at 0.5 μg/ml. Forty-nine, 49 and 46 patients were enrolled into the 3 respective groups before study closure. The proportion of patients with hypoxemia events differed significantly between groups (67.3 vs. 46.9 vs. 41.3%, p = 0.027. Hypotension events, induction and recovery time and propofol doses were not different. The Ce of induction differed significantly between groups (2.4±0.5 vs. 2.1±0.4 vs. 2.1±0.3 μg/ml, p = 0.005 and the Ce of procedures was higher at 0.5 μg/ml titration (2.4±0.5 vs. 2.1±0.4 vs. 2.2±0.3 μg/ml, p = 0.006. The adjustment frequency tended to be higher for titration at 0.1 μg/ml but was not statistically significant (2 (0∼6 vs. 3 (0∼6 vs. 3 (0∼11. Subgroup analysis revealed 14% of all patients required no further adjustment during the whole sedation. Comparing patients requiring at least one adjustment with those who did not, they were observed to have a shorter induction time (87.6±34.9 vs. 226.9±147.9 sec, p<0.001, a smaller induction dose and Ce (32.5±4.1 vs. 56.8±22.7 mg, p<0.001; 1.76±0.17 vs. 2.28 ±0.41, p<0.001, respectively, and less hypoxemia and hypotension (15.8 vs.56.9%, p = 0.001; 0 vs. 24.1%, p = 0.008, respectively.Titration at 0.5 μg/ml is risky for FB sedation.

    Purpose: To compare spiral computed tomography (CT) and electron-beam CT (EBT) for 3D and virtual CT-bronchoscopy. Materials and methods: 17 patients with various disorders of the tracheobronchial system were examined using fiberoptic bronchoscopy, spiral CT and EBT. 3D images were reconstructed from CT data sets using automated segmentation based on volume-growing methods. Surface-rendered, volume-rendered, and hybrid reconstructions were visualized in real time using a data helmet. Results: All data sets could be processed to high-quality three-dimensional (3D) and virtual reconstructions. The reduction of motion artifacts due to shorter scan times made EBT data sets better suited for automated segmentation and less susceptible to motion artifacts. 3D and virtual reconstructions did not increase the diagnostic sensitivity of CT compared to axial reconstructions alone. Conclusions: Shorter scan times of CT imaging yield higher-quality 3D and virtual reconstructions. Modern reconstruction techniques are valuable visualization tools for select indications and are the prerequisite for future developments in computer-aided medicine. (orig.)

However as 30% to 50% of the bearers of pulmonary tuberculosis have a negative sputum smear or have no sputum the fiber bronchoscopy acquires a special importance. OBJECTIVES: To evaluate the sensitivity of the specimens collected by means of the fiber bronchoscopy (brochoalveolar lavage and transbronchial biopsy for the diagnosis of patients suspected of having pulmonary tuberculosis, without confirmation by sputum bacilloscopy. METHOD: By review of the ledgers of fiber bronchoscopies carried out from March 1997 to March 2001, we identified and included in the study patients over 18 years of age and referred with suspicion of tuberculosis and at least three negative sputum smears. Data regarding age, gender, changes detected at thorax imaging and endoscopy were collected. RESULTS: Fifty-two patients with ages ranging from 19 to 77 years (median of 39, were included, 58% were of the male gender and 37% were patients from the Official Health System. Prevailing finding at chest X-ray was the alveolar infiltrate (80%. In 35 patients tuberculosis was the final diagnosis (one with associated neoplasia; in 28 patients (80% diagnosis was achieved by bronchoscopy. Other diagnoses disclosed by bronchoscopy were neoplasias, histoplasmosis chronic eosinophil alvelolitis, pneumonia by Pneumocystis carinii and pulmonary fibrosis. CONCLUSION: results of this study point to the use of fiber bronchoscopy in patients suspect of tuberculosis, not diagnosed thorough sputum bacilloscopy, not only for pulmonary tuberculosis but also of those that represent differential diagnoses.

  3. SU-C-BRA-07: Virtual Bronchoscopy-Guided IMRT Planning for Mapping and Avoiding Radiation Injury to the Airway Tree in Lung SAbR

    International Nuclear Information System (INIS)

    Purpose: Post-treatment radiation injury to central and peripheral airways is a potentially important, yet under-investigated determinant of toxicity in lung stereotactic ablative radiotherapy (SAbR). We integrate virtual bronchoscopy technology into the radiotherapy planning process to spatially map and quantify the radiosensitivity of bronchial segments, and propose novel IMRT planning that limits airway dose through non-isotropic intermediate- and low-dose spillage. Methods: Pre- and ∼8.5 months post-SAbR diagnostic-quality CT scans were retrospectively collected from six NSCLC patients (50–60Gy in 3–5 fractions). From each scan, ∼5 branching levels of the bronchial tree were segmented using LungPoint, a virtual bronchoscopic navigation system. The pre-SAbR CT and the segmented bronchial tree were imported into the Eclipse treatment planning system and deformably registered to the planning CT. The five-fraction equivalent dose from the clinically-delivered plan was calculated for each segment using the Universal Survival Curve model. The pre- and post-SAbR CTs were used to evaluate radiation-induced segmental collapse. Two of six patients exhibited significant segmental collapse with associated atelectasis and fibrosis, and were re-planned using IMRT. Results: Multivariate stepwise logistic regression over six patients (81 segments) showed that D0.01cc (minimum point dose within the 0.01cc receiving highest dose) was a significant independent factor associated with collapse (odds-ratio=1.17, p=0.010). The D0.01cc threshold for collapse was 57Gy, above which, collapse rate was 45%. In the two patients exhibiting segmental collapse, 22 out of 32 segments showed D0.01cc >57Gy. IMRT re-planning reduced D0.01cc below 57Gy in 15 of the 22 segments (68%) while simultaneously achieving the original clinical plan objectives for PTV coverage and OAR-sparing. Conclusion: Our results indicate that the administration of lung SAbR can Result in significant injury to

    The role of flexible fiberoptic bronchoscopy (FFB) in the evaluation of pediatric lung disease has expanded dramatically since the original description of the procedure by Wood and Fink in 1978.FFB can be used to evaluate airway anatomy, obtain secretions for culture and biochemical analysis and obtain airway cells or parenchymal tissues for evaluation. Both the upper and lower airway can be examined during FFB. Visual examination can diagnose a variety of congenital abnormalities ( Table 1 ). During FFB a dynamic evaluation of the airways, including the movement of the glottis, vocal cords and lower airways during the respiratory cycle can be performed. These observations can diagnose airway collapse due to malacia or obstruction due to external compression. Additionally, the diameter of the airway lumen and character of the airway mucosa can easily be evaluated. FFB can also identify airway obstruction by secretions and mucus plugs, blood, foreign bodies or masses. Bronchoalveolar lavage (BAL) allows collection of airway and alveolar secretions for evaluation of cellular and immunologic components, evidence of infection and cytology. Therapeutic lavage can be used to treat atelectasis by removing secretions obstructing airways. This approach can be helpful in children with inspissated secretions obstructing both large and small airways ( Figure 1 ). Therapeutic lavage has also been used in the treatment of alveolar proteinosis. Bronchial brushing can add information to bronchoscopic examination by obtaining airway epithelial cells for cytology, to identify intracellular pathogens and to evaluate cilia. Studies have demonstrated the utility of bronchial brushings for the isolation, characterization and culture of primary epithelial cells from children with asthma. Endobronchial biopsies are used for histopathological and immunocytochemical analysis and microbiological culture. Biopsies are often performed to assess cilia function and architecture. In addition

    Full Text Available A aspiração de corpo estranho (ACE para o trato respiratório é um problema comum em pacientes pediátricos, em especial abaixo dos três anos de idade. Na avaliação radiológica inicial, cerca de 30% dos pacientes apresentam radiograma de tórax normal. A tomografia com broncoscopia virtual (BV pode auxiliar no diagnóstico precoce desse quadro e seu pronto manejo. O tratamento definitivo se dá com a retirada do corpo estranho através de broncoscopia rígida e mediante anestesia geral. O objetivo deste trabalho foi descrever o uso da BV na abordagem de dois pacientes com suspeita de ACE e realizar uma revisão da literatura sobre este tópico. Os dois pacientes tiveram início súbito de sintomas respiratórios e relato de tosse ou engasgo com alimentos antecedendo o quadro. Os pacientes foram submetidos à BV, e foi detectada a presença de corpo estranho endobrônquico em ambos os casos, com remoção posterior por broncoscopia rígida convencional em um caso. A BV é um método não-invasivo recente e com potencial para detectar a presença de corpo estranho na via respiratória em crianças. Em casos selecionados, BV pode auxiliar na localização correta do corpo estranho e até mesmo evitar o procedimento de broncoscopia rígida na ausência de corpo estranho.Foreign body aspiration (FBA into the tracheobronchial tree is a common problem in children, especially in those under three years of age. Preliminary radiological evaluation reveals normal chest X-rays in nearly 30% of such patients.

    Objective To investigate the value of the liquid⁃based cytology ( LBC ) of brushing specimens obtained via fiberoptic bronchoscopy for clinical diagnosis of lung cancer. Methods We retrospectively analyzed the LBC cases in our hospital from January 2011 to May 2012, and evaluate its role in the diagnosis of lung cancer. Results The clinical data of a total of 4 380 cases were reviewed and 3 763 of them had histopathological or clinical follow⁃up results ( including 3 306 lung cancer cases and 457 benign lesion cases) . The sensitivity, specificity, and accuracy of LBC diagnosis for lung cancer were 72. 4%(2 392/3 306), 99.3%(454/457) and 75.6%(2 846/3 763), respectively. Of the 1 992 lung cancer cases diagnosed by brushing LBC, 528 cases(26.5%) were failed to take forceps biopsy and 113 cases(5.7%) showed negative forceps biopsy results. The accurate rate of subtyping of LBC for non⁃small cell carcinoma and small cell carcinoma was 99.0% (1 487/1 502) (P0.05). Conclusions Fiberoptic bronchoscopic brushing liquid⁃based cytology can significantly improve the detection rate of lung cancer, and have a high specificity and accurate rate of subtyping. It is an effective tool for the diagnosis and subtyping of lung cancer.%目的:探讨纤维支气管镜( FOB)下刷取标本液基细胞学检查对临床诊断肺癌的价值。方法回顾性分析2011年1月至2012年5月中国医学科学院肿瘤医院收治的FOB下刷取标本液基细胞学病例资料,评价其在肺癌诊断中的意义。结果共收集4380例,其中3763例有组织病理学及临床随访结果(肺癌3306例,良性病变457例)。刷取标本液基细胞学诊断肺癌的敏感性、特异性和准确性分别为72.4%(2392/3306)、99.3%(454/457)和75.6%(2846/3763)。在液基细胞学诊断为癌的1992例病例中,528例(26.5%)未取到活检,113例(5.7%)活检阴性。液基细胞学对非小细胞癌和小细胞癌

    Bronchoscopy remains a pivotal diagnostic and therapeutic intervention in pediatric patients undergoing lung transplantation (LTx). Whether performed as part of a surveillance protocol or if clinically indicated, fibre-optic bronchoscopy allows direct visualization of the transplanted allograft, and in particular, an assessment of the patency of the bronchial anastomosis (or tracheal anastomosis following heart-lung transplantation). Additionally, bronchoscopy facilitates differentiation of infective processes from rejection episodes through collection and subsequent assessment of bronchoalveolar lavage (BAL) and transbronchial biopsy (TBBx) samples. Indeed, the diagnostic criteria for the grading of acute cellular rejection is dependent upon the histopathological assessment of biopsy samples collected at the time of bronchoscopy. Typically, performed in an out-patient setting, bronchoscopy is generally a safe procedure, although complications related to hemorrhage and pneumothorax are occasionally seen. Airway complications, including stenosis, malacia, and dehiscence are diagnosed at bronchoscopy, and subsequent management including balloon dilatation, laser therapy and stent insertion can also be performed bronchoscopically. Finally, bronchoscopy has been and continues to be an important research tool allowing a better understanding of the immuno-biology of the lung allograft through the collection and analysis of collected BAL and TBBx samples. Whilst new investigational tools continue to evolve, the simple visualization and collection of samples within the lung allograft by bronchoscopy remains the gold standard in the evaluation of the lung allograft. This review describes the use and experience of bronchoscopy following lung transplantation in the pediatric setting.

    2003-01-01

    Full Text Available Background. Fluorescence bronchoscopy is one of the methods of the early detection of lung cancer that involves the large airways. The method is based on the detection of the altered autofluorescence of malignantly transformed tissue, and confirmed by biopsy and histopathologic examination. Method. Fluorescence bronchoscopy was performed in 18 patients, mean age of 51.2 years (male n=12, female n=6 due to the suspected lung cancer. Fluorescence bronchoscopy was performed using the Xillix LIFE-Lung System Vancouver, Canada. After conventional white-light bronchoscopy, the tracheobronchial tree was illuminated by blue light (442 nm using helium-cadmium laser, and the results of autofluorescence were classified into three classes. Normal mucosa was of green fluorescence (Class I abnormal mucosa was red or dark brown fluorescence (Class II and II, which was the indication for performing biopsy. Results. Normal endoscopy findings were established in 15 patients by conventional bronchoscopy. In the same group, by fluorescence bronchoscopy, Class I of fluorescence (normal finding was found in 9 patients, while Class II changes occured in 6 patients. Histopathologic analysis of bronchial mucosa with Class II changes was performed detecting planocellular carcinoma in situ in one patient. Tumor-like changes were detected in 3 patients by conventional bronchoscopy and were determined as Class III changes by fluorescence bronchoscopy. By the biopsy of these chages carcinoma was documented in 2 patients while in one patient metaplasia of epithelium and granulation tissue around aspirated foreign body was detected. Conclusion. Fluorescence bronchoscopy is one of the methods for detecting metaplasia, carcinoma in situ and cancerous changes of bronchial epithelium in the large airways. However, the high rate of falsely positive findings represents a limitation of this method.

  19. Fatal Pulmonary Hemorrhage Through Fiberoptic Broncoscopy in a Well Controlled Diabetic Female With Mucormycosis

    2008-01-01

    Full Text Available A rare case of invasive pulmonary mucormycosis complicated by fatal massive haemoptysis through bronchoscopy in a patient with a well controlled diabetes is reported. Histological features of infection are reported and the characteristic aspects of the staining are discussed. Fiberoptic bronchoscopy revealed bilateral obstruction of the segmental bronchi and fatal massive bleeding occurring because of biopsy sampling. Caution is warranted in the use of bronchoscopy sampling in patients with radiological features of cavitated lesions of fungal origins. Better preventive and early therapeutic antifungal treatments are needed to avoid this serious complication.

    A 48-year-old man was referred for an abnormal shadow in his chest x-ray. Transbronchial needle aspiration cytology was performed at the mediastinal necrotic lymph node #7, and he was diagnosed as having small cell carcinoma. Fifteen days after bronchoscopy, sudden cardiac tamponade occurred and pericardial drainage suggested a diagnosis of bacterial pericarditis. He was successfully treated by drainage and administration of antibiotics. Complication of bacterial pericarditis associated with bronchoscopy is rare. However, physicians should watch for the appearance of this condition for up to 3 weeks after bronchoscopy, especially in cases with necrotic lymph nodes. PMID:27058720

  6. Accidental aspiration of head scarf pin in left bronchus piercing the lung parenchyma: A rare case in a child

    Science.gov (United States)

    Parvez, Yusuf; Kandath, Mohammed Ashraf

    2016-01-01

    Foreign body (FB) aspiration is commonly seen in children but less commonly in adolescents. Headscarf pin aspiration is common in Muslim girls, who inappropriately place the pins between their lips while securing the scarf on the head. Bronchoscopy is the treatment modality of choice, and surgery is rarely required. An 11-year-old girl was admitted as a case of accidental aspiration of headscarf pin. X-ray chest showed a radiopaque object in the left bronchus piercing the lung parenchyma. Computed tomography (CT) chest confirmed the diagnosis. The headscarf pin was removed by flexible bronchoscopy as the ear, nose, and throat (ENT) surgeon failed to remove it by rigid bronchoscopy. The FB was removed successfully and the patient was discharged home. Removal of a sharp pin by bronchoscopy is difficult, especially if it pierces the lung parenchyma. In our case, the pin was bent by forceps and then removed by a flexible bronchoscope, which requires a highly skilled professional. PMID:27578937

Subgroups were analyzed by diagnostic method as defined by the National Burn Repository. All diagnostic methods listed for each patient were included, comparing mortality, hospital days, intensive care unit (ICU) days, and ventilator days (VDs). Z-tests, t-tests, and linear regression were used with a statistical significance of P value of less than .05. The database query yielded 9775 patients diagnosed with inhalation injury. The greatest increase in mortality was associated with diagnosis by bronchoscopy or carbon monoxide poisoning. A relative increase in hospital days was noted with diagnosis by bronchoscopy (9 days) or history (2 days). A relative increase in ICU days was associated with diagnosis according to bronchoscopy (8 days), clinical findings (2 days), or history (2 days). A relative increase in VDs was associated with diagnosis by bronchoscopy (6 days) or carbon monoxide poisoning (3 days). The combination of diagnosis by bronchoscopy and clinical findings increased the relative difference across all comparison measures. The combination of diagnosis by bronchoscopy and carbon monoxide poisoning exhibited decreased relative differences when compared with bronchoscopy alone. Diagnosis by laryngoscopy showed no mortality or association with poor outcomes. Bronchoscopic evidence of inhalation injury proved most useful, predicting increased mortality, hospital, ICU, and VDs. A combined diagnosis determined by clinical findings and bronchoscopy should be considered for clinical practice. PMID:26594867

    Full Text Available The extraction of aspirated foreign bodies can prove challenging at times, requiring even rigid bronchoscopy. Cryotherapy probes have been reported to help with extraction of foreign bodies. We present a case where successful "cryoextraction" was performed on an aspirated chewing gum. The case highlights the fact that this technique is useful to extract all materials that have water content. This technique can be performed through flexible bronchoscopy and can save patients from more aggressive approaches.

    Objective: To analyze the clinical features of lung cancer diagnosed by bronchoscopy. Methods:The clinical features of2168 patients with lung cancer diagnosed by bronchoscopy were retrospectively analyzed, including gender, age, pathological type, diseased region, manifestations under bronchoscopy and methods of drawing materials. Results:The ratio of male/female was 4.8:1 and the peak onset age was 60~69 years old. The major pathological type was squamous cell carcinoma (44.5%), then adenocarcinoma (25.9%) and small cell lung cancer (18.3%). The incidence of squamous cell carcinoma was the highest in males (50.6%), while that of adenocarcinoma in females (56.2%). The positive diagnostic rates of forceps biopsy, brush biopsy, bronchial alveolar lavage and transbronchial needle aspiration were 81.6%, 49.4%, 18.2% and 62.6%, respectively, whereas that of biopsy combined with brush biopsy came up to 89.0%. Conclusion: Bronchoscopy is an important method in diagnosis of lung cancer. Different ages and genders of patients with lung cancer have different onset, and the distribution of pathological types is diverse. Attaching more importance to bronchoscopy and improving biopsy technique can signiifcantly improve the diagnostic rate and provide reliable evidences for clinical treatment.

    Full Text Available Massive hemoptysis can be a life threatening condition and needs urgent treatment in lung cancer. In the fiberoptic bronchoscopy of a fifty-two-year-old who was admitted with hemoptysis, left upper lobe upper division orifice was seen totally obstructed with a submucosal infiltration. One hour after the mucosal biopsies, massive hemoptysis occurred. Urgent rigid bronchoscopy was performed. The left main bronchus was occluded by sterile gauze. After cleaning of the coagulum patient was intubated and charged to intensive care unit. The next day, rigid bronchoscopy was repeated and the bleeding was observed to continue from the left upper lobe. Removing the gauze, 14 × 10 × 10 mm silicon Y stent was inserted in the left main bronchus after adjustments were made. Bleeding was stopped after insertion of the stent and patient could be extubated. In this case a successful control of hemoptysis was sustained after insertion of a customized silicon stent was presented.

    Cushing's syndrome occurred in 1-5% of cases of bronchial carcinoids. In this paper we describe a case of typical bronchial carcinoid in a nonsmoker young male with clinical manifestations mimicking a Cushing's syndrome. The patient performed chest radiograph and computed tomography. Fiberoptic bronchoscopy revealed the presence of an endobronchial mass occluding the bronchus intermedius. A rigid bronchoscopy was necessary for the conclusive diagnosis and for partial resection of the intraluminal tumor. Despite of the presence of Cushingoid features, the normal blood levels of ACTH and cortisol excluded the coexistence of a Cushing's syndrome.

    A 66-year-old woman with a background of chronic lymphocytic leukemia (CLL) was admitted to the hospital on several occasions with recurrent episodes of community-acquired pneumonia. Computed tomography and bronchoscopy revealed multiple obstructing endobronchial polyps. Post-obstructive pneumonia together with immunoglobulin G deficiency was considered the most likely cause of these recurrent infections. Bronchoscopy was performed for removal of the critically obstructing lesions. Histopathology revealed replacement of bronchial mucosa with CLL deposits. Despite a brief window of infection-free survival following therapy, she remained susceptible to pneumonia with further hospital admissions and eventually died from her disease. PMID:26090107

    Full Text Available Background: Miliary tuberculosis is often treated empirically in India in the absence of a positive diagnosis based on sputum examination. We investigated the role of fiberoptic bronchoscopy for diagnosis of this disease. Methods : Records of patients undergoing fiberoptic bronchoscopy and bronchoscopic lung biopsy, and diagnosed to have miliary tuberculosis, over a four year period were evaluated. Two to four lung biopsy specimens were obtained from each patient and examined microscopically after Hematoxylin-eosin and Zeihl-Neelson staining. Results : Thirty one patients of miliary tuberculosis (19 men and 12 women underwent fiberoptic bronchoscopy during the study period. No endobronchial abnormality was noted in any patient. Bronchoscopic lung biopsy yielded adeqaute specimen in all but one patient. Granulomatous inflammation was noted in 21 (67.7% patients on histopathological evaluation of biopsy specimens; of them, acid-fast bacilli were demonstrated in one patient. One patient (3.2% had normal alveolar architecture. In the other 8 patients (25.8%, nonspecific pulmonary interstitial inflammation and/or mild fibrosis were seen. Bronchial wash specimens showed acid-fast bacilli in only one patient; this patient also had granulomatous inflammation on lung biopsy. All patients tolerated bronchoscopy well and there were no procedure-related complications. Conclusion: Bronchoscopic lung biopsy is a safe procedure and an effective method of establishing diagnosis of miliary tuberculosis in a majority of patients with this disease. Bronchial washings do not provide significant additional information in this regard.

    Endobronchial ultrasound (EBUS) is now recommended as a standard procedure for in vivo verification of extraluminal diagnostic sites during cancer-staging bronchoscopy. Yet, physicians vary considerably in their skills at using EBUS effectively. Regarding existing bronchoscopy guidance systems, studies have shown their effectiveness in the lung-cancer management process. With such a system, a patient's X-ray computed tomography (CT) scan is used to plan a procedure to regions of interest (ROIs). This plan is then used during follow-on guided bronchoscopy. Recent clinical guidelines for lung cancer, however, also dictate using positron emission tomography (PET) imaging for identifying suspicious ROIs and aiding in the cancer-staging process. While researchers have attempted to use guided bronchoscopy systems in tandem with PET imaging and EBUS, no true EBUS-centric guidance system exists. We now propose a full multimodal image-based methodology for guiding EBUS. The complete methodology involves two components: 1) a procedure planning protocol that gives bronchoscope movements appropriate for live EBUS positioning; and 2) a guidance strategy and associated system graphical user interface (GUI) designed for image-guided EBUS. We present results demonstrating the operation of the system.

    BACKGROUND: The development of a fistula between the tracheobronchial tree and the gastric conduit post esophagectomy is a rare and often fatal complication. CASE PRESENTATION: A 68 year old man underwent radical esophagectomy for esophageal adenocarcinoma. On postoperative day 14 the nasogastric drainage bag dramatically filled with air, without deterioration in respiratory function or progressive sepsis. A fiberoptic bronchoscopy was performed which demonstrated a gastro-bronchial fistula in the posterior aspect of the left main bronchus. He was managed conservatively with antibiotics, enteral nutrition via jejunostomy, and non-invasive respiratory support. A follow- up bronchoscopy 60 days after the diagnostic bronchoscopy, confirmed spontaneous closure of the fistula CONCLUSIONS: This is the first such case where a conservative approach with no surgery or endoprosthesis resulted in a successful outcome, with fistula closure confirmed at subsequent bronchoscopy. Our experience would suggest that in very carefully selected cases where bronchopulmonary contamination from the fistula is minimal or absent, there is no associated inflammation of the tracheobronchial tree and the patient is stable from a respiratory point of view without evidence of sepsis, there may be a role for a trial of conservative management.

    A patient with advanced mycosis fungoides developed neurologic and respiratory symptoms and signs following multiple courses of chemotherapy and radiotherapy. Various repeated diagnostic procedures - including cranial computerized tomography and fiberoptic bronchoscopy with transbronchial lung biopsy - failed to demonstrate an unusual involvement of the brain and lungs by myocosis fungoides. Radionuclide brain imaging and gallium imaging of the lungs demonstrated diffuse lesions confirmed at autopsy.

    Tracheobronchomalacia (TBM) is defined as an excessive collapse of the intrathoracic trachea. Bronchoscopy is the gold standard for diagnosing TBM; however it has major disadvantages, such as general anaesthesia. Cine computed tomography (CT) is a noninvasive alternative used to diagnose TBM, but its use in children is restricted by ionising radiation. Our aim was to evaluate the feasibility of spirometer-controlled cine magnetic resonance imaging (MRI) as an alternative to cine-CT in a retrospective study. 12 children with a mean age (range) of 12 years (7-17 years), suspected of having TBM, underwent cine-MRI. Static scans were acquired at end-inspiration and expiration covering the thorax using a three-dimensional spoiled gradient echo sequence. Three-dimensional dynamic scans were performed covering only the central airways. TBM was defined as a decrease of the trachea or bronchi diameter >50% at end-expiration in the static and dynamic scans. The success rate of the cine-MRI protocol was 92%. Cine-MRI was compared with bronchoscopy or chest CT in seven subjects. TBM was diagnosed by cine-MRI in seven (58%) out of 12 children and was confirmed by bronchoscopy or CT. In four patients, cine-MRI demonstrated tracheal narrowing that was not present in the static scans. Spirometer controlled cine-MRI is a promising technique to assess TBM in children and has the potential to replace bronchoscopy.

    Objective In the aspiration of animal fats, bronchoscopy is promptly necessary, not only for removing the foreign body but also for its therapeutic importance in order to avoid severe lipoid pneumonia, because fat acids are very toxic for the bronchial mucosa. Methods Patient 84 years old, nonsmoker, with a medical history of heart disease under acenocoumarol, referred accidental aspiration of cooked animal intestine, 12 hours ago, with rough cough and dyspnea that started instantly. To be noted, the patient presented with wheezing in both lungs. Thoracic CT scan images reveal a suspicion of aspiration, confirmed by indirectly evidence (right middle lobe atelectasis and also mediastinum transposition to the left and consolidation with atelectasis in the left lower lobe, as evidence of previous infections-possible aspirations, emerged from his case story). Therefore, urgent bronchoscopy was performed and the foreign body, that was movable with the cough, was removed. Bronchial lavage was performed due to acute infection in whole bronchial tree. A reactive granuloma tissue was noted in the entrance of the middle lobe, but because of the anticoagulant intake biopsy wasn’t performed. During his hospitalization the patient was under antibiotics, bronchodilators and corticosteroids. Results At the time of revaluation, two weeks after, the patient was non symptomatic while the new CT scan showed evidence of residual infection in the left lung and atelectasis of the right middle lobe on the left. Bronchoscopy was reperformed and biopsy was taken in the entrance of the right middle lobe because of the noted reactive granuloma tissue, seen at the first bronchoscopy. No signs of bronchial inflammation were found (impressive improvement due to immediate intervention). Conclusions Animal fat aspiration causes acute bronchial inflammation and therefore, lipoid pneumonia within a few hours, due to rapid hydrolysis of releasing fatty acids. Removing the animal fat with the

    Full Text Available Abstract Introduction A tracheobronchial foreign body is a rarely mentioned cause of massive hemoptysis. Although an aspirated toothpick is a well-known cause of traumatic injury to the respiratory tract, a similar device called a dental floss pick, which is much larger than a toothpick, has never been described as a tracheobronchial foreign body. Case presentation We report a case of massive hemoptysis in a 32-year-old man due to a dental floss pick in the left main bronchus. Flexible fiberoptic bronchoscopy was successful in removing the foreign body. Conclusion Tracheobronchial foreign body can be a medical emergency requiring immediate intervention and massive hemoptysis may be the presenting symptom. Flexible fiberoptic bronchoscopy is recommended as the first-line treatment modality for tracheobronchial foreign body removal. A dental floss pick may present as a tracheobronchial foreign body and can reside in the airway asymptomatically for many years.

    Full Text Available Congenital lobar emphysema (CLE, also called infantile lobar emphysema, is a respiratory disease that occurs in infants when air enters the lungs but cannot leave easily. It results from cartilage deficiency and bronchomalacia causing distal air trapping and respiratory distress. Acquired forms are usually associated with chronic lung disease or endobronchial obstruction such as mucus plugging. "nWe report a pedunculated endobronchial polyp in a 18-month-old infant causing hyperinflation of the left upper lobe, which is the most common site of CLE, and presented with sudden respiratory distress. The polyp was seen in the left upper bronchus at bronchoscopy. The imaging features of this case in CXR and CT scan will be shown and the possible etiological links with mechanical bronchial obstruction will be discussed. "nWe also emphasize the value of bronchoscopy prior to lobectomy in cases of congenital lobar emphysema (CLE.

    Endobronchial cartilage rupture is a rare clinical condition, which can present in patients with severe emphysema with sudden onset shortness of breath. We present a case of a 62-year-old male who presented to our emergency department with sudden onset shortness of breath. Chest X-ray showed lung hyperinflation and a right lung field vague small density. Chest Computed Tomography confirmed the presence of right middle lobe collapse. Bronchoscopy revealed partial right middle lobe atelectasis and an endobronchial cartilage rupture. Endobronchial cartilage rupture is a rare condition that can present as sudden onset shortness of breath due to lobar collapse in patients with emphysema and can be triggered by cough. Bronchoscopic findings include finding a collapsed lung lobe and a visible ruptured endobronchial cartilage. A high index of suspicion, chest imaging, and early bronchoscopy can aid in the diagnosis and help prevent complications. PMID:27525149

    We present a case of 63-year-old man who was referred to the emergency department with a right-sided pneumothorax. He had a history of spontaneous pneumothorax for 2 times. The chest computed tomographic scan showed tracheobronchomegaly with an increase in the diameter of the trachea and right and left main bronchus. Fiberoptic bronchoscopy revealed enlarged trachea and both main bronchus with diverticulas. These findings are consistent with a diagnosis of Mounier-Kuhn syndrome. Mounier-Kuhn syndrome is a rare clinical and radiologic condition. It is characterized by a tracheal and bronchial dilation. Diagnosis is made by computed tomography and bronchoscopy. Mounier-Kuhn syndrome should be kept in mind in the differential diagnosis of recurrent spontaneous pneumothorax. PMID:26127019

    Positron emission tomography (PET) and X-ray computed tomography (CT) serve as major diagnostic imaging modalities in the lung-cancer staging process. Modern scanners provide co-registered whole-body PET/CT studies, collected while the patient breathes freely, and high-resolution chest CT scans, collected under a brief patient breath hold. Unfortunately, no method exists for registering a PET/CT study into the space of a high-resolution chest CT scan. If this could be done, vital diagnostic information offered by the PET/CT study could be brought seamlessly into the procedure plan used during live cancer-staging bronchoscopy. We propose a method for the deformable registration of whole-body PET/CT data into the space of a high-resolution chest CT study. We then demonstrate its potential for procedure planning and subsequent use in multimodal image-guided bronchoscopy.

    Full Text Available Tracheobronchopathia Osteochondroplastica (TO is a rare disorder of large airways with unknown etiology which is characterized by cartilaginous and bony nodules lining the mucosa of the trachea and major bronchi. Generally, it is benign and asymptomatic, but it may present with cough, exertional dyspnea and wheezing. It could therefore be mistaken with asthma and chronic obstructive pulmonary disease . The diagnosis is usually made on bronchoscopy and confirmed on histology .We describe two cases of TO with characteristic bronchoscopic and histological findings. The first one had exertional dyspnea and hoarseness for more than 3 years and the second one had exertional dyspnea for more than 10 years .In both of the cases, fiber optic bronchoscopy was performed which revealed numerous white,hard,irregular nodules on trachea and main bronchi. The pathologic diagnosis of bronchoscopic biopsy was TO.

    2006-01-01

    Full Text Available We report a young lady, who was labeled as a case of refractory asthma for a few years, based on history of shortness of breath on minimal exertion, noisy breathing and normal chest radiograph. Repeated upper airway exam by an otolaryngologist and computerized tomography scan, were normal. On presentation to our hospital, she was diagnosed to have fixed upper airway obstruction, based on classical flow-volume loop findings. Fibroptic bronchoscopy revealed a web-shaped subglottic stenosis. The histopathology of a biopsy taken from that area, showed non-specific inflammation. No cause for this stenosis could be identified. The patient was managed with rigid bronchoscopy dilatation, without recurrence. We report this case as idiopathic subglottic stenosis, that was misdiagnosed as refractory bronchial asthma, stressing the importance of performing spirometry in the clinic.

    The disposable plastic beverage cup is not usually regarded as hazardous to young children. Certain varieties of these products however, are manufactured from a brittle, clear plastic that easily cracks and fragments. While most conscientious parents keep their children safe from peanuts, balloons, and other known choking hazards, a child can surreptitiously bite a cup edge and aspirate the fragment. We report two cases of foreign body aspiration involving clear plastic cups that went undetected one of which remained 21 months following a negative rigid bronchoscopy. Diagnostic difficulties are related to the transparency and radiolucency of these objects. When suspicious of foreign body aspiration in children, otolaryngologists should inquire about the availability of clear plastic cups in the household and be mindful of the diagnostic pitfalls. Further investigations including CT scanning and repeat bronchoscopy may be helpful in cases of suspected missed foreign bodies. An educational campaign aimed at prevention and placement of product package warning labels should be established.

    The authors describe the case of a man, 46 years old, former smoker, former bird breeder, followed in the service of Imunoallergology for bronchospasm without response to the treatment. After experiencing an hemoptysis he was admitted in our service. He was submitted to many exams, which include a flexible bronchoscopy. This technique allows the identification of an endobronquial necrotic mass, which almost obstructed the main right bronchus. In order to obtain a bigger and more representative sample a rigid bronchoscopy was performed. This technique showed a broncholith, which was partially removed, and a bronchial fistula. Actually he is assimptomatic and under annual surveillance. First described for Aristoteles, the broncholithiasis is defined by the presence of stones in the bronchial tree. It is a very rare pathology, with a variable clinical expression, which must be considered whenever there is respiratory complaints in association with hilar or mediastinic calcifications.

    2008-01-01

    Fibered confocal fluorescence microscopy (FCFM) is a new technique that can be used during a bronchoscopy to analyze the nature of the human bronchial and alveolar mucosa fluorescence microstructure. An endoscopic fibered confocal fluorescence microscopy system with spectroscopic analysis capability was developed allowing real-time, simultaneous images and emission spectra acquisition at 488 nm excitation using a flexible miniprobe that could be introduced into small airways. This flexible 1.4 mm miniprobe can be introduced into the working channel of a flexible endoscope and gently advanced through the bronchial tree to the alveoli. FCFM in conjunction with bronchoscopy is able to image the in vivo autofluorescence structure of the bronchial mucosae but also the alveolar respiratory network outside of the usual field of view. Microscopic and spectral analysis showed that the signal mainly originates from the elastin component of the bronchial subepithelial layer. In non smokers, the system images the elastin...

    Reported here are 2 patients with connective tissue disease who developed pulmonary nocardiosis. Case 1 involved a 73-year-old man with malignant rheumatoid arthritis treated with prednisolone 25 mg/day. Chest X-rays revealed a pulmonary cavity and bronchoscopy detected Nocardia species. The patient was successfully treated with trimethoprim/sulfamethoxazole. Case 2 involved a 41-year-old woman with systemic lupus erythematosus. The patient received remission induction therapy with 50 mg/day of prednisolone and tacrolimus. Six weeks later, a chest CT scan revealed a pulmonary cavity; bronchoscopy resulted in a diagnosis of pulmonary nocardiosis. The patient had difficulty tolerating trimethoprim/sulfamethoxazole, so she was switched to and successfully treated with imipenem/cilastatin and amikacin.

    Full Text Available Hydatid cyst disease of lungs may not be symptomatic. It may present as spontaneous rupture in pleura or a bronchus. During spontaneous breathing, cyst content of endobronchially ruptured pulmonary hydatid cyst is mostly evacuated by coughing. However, during positive pressure ventilation such extruded fragments may lodge into smaller airway leading to an airway catastrophe. We present such accidental endobronchial rupture of pulmonary hydatid cyst during surgery, its prompt detection, and management by rigid bronchoscopy.

    Full Text Available Background: There is paucity of data regarding the morbidity and mortality of rigid bronchoscopy in children for foreign body (FB retrieval from India. The aim was to audit data regarding anaesthetic management of rigid bronchoscopy in children and associated morbidity and mortality. Materials and Methods: Hospital records of all patients below 18 years of age undergoing rigid bronchoscopy for suspected FB aspiration (FBA between January 1, 2002 and December 31, 2011 were audited to assess their demographic profile, anaesthetic management, complications, and postoperative outcomes. The children were divided into early and late diagnosis groups depending on whether they presented to the hospital within 24 hours of FBA, or later. Results: One hundred and forty children, predominantly male (75%, with an average age of 1-year and 8 months, presented to our hospital for rigid bronchoscopy during the study period. Majority of children presented in the late diagnosis group (59.29% vs. 40.71%. The penetration syndrome was observed in 22% of patients. Majority of patients aspirated an organic FB (organic: Inorganic FB = 3:1, with peanuts being the most common (49.28%. A significantly higher number of children presented with cough (P = 0.0001 and history of choking (P = 0.0022 in the early diagnosis group and crepitations (P = 0.0011 in the late diagnosis group. Major complications included cardiac arrest (2.1%, pneumothorax (0.7%, and laryngeal oedema (9.3%. The average duration of hospitalization in our series was 3.08 ± 0.7 days. Conclusions: Foreign body aspiration causes considerable morbidity, especially when diagnosis is delayed.

    Bridging bronchus (BB) is a rare, congenital bronchial anomaly that is frequently associated with congenital cardiac malformations, especially left pulmonary artery sling. It represents an anomalous bronchus to the right originating from the left main bronchus. Discrimination from other bronchial anomalies is important, since BB is frequently associated with bronchial stenoses due to abnormal cartilage rings. This case study describes the findings of bronchoscopy, bronchography and multidetector computed tomography (MDCT) in three patients. Bronchoscopy was helpful in the description of the severity and length of bronchial stenoses. However, it was not possible to establish a diagnosis of BB based on this method in two patients, since it is difficult or even impossible to differentiate the bifurcation from the pseudocarina. It was not possible to establish the correct diagnosis in all patients based on bronchography or MDCT. MDCT was able to depict the relationship of bronchial and vascular structures, which is particularly important in patients with pulmonary artery sling. Multidetector computed tomography is preferable to bronchography as it is less invasive and due to its short acquisition time it can be performed in children with severe respiratory disease. In the current authors' experience, detection of cartilage rings still requires flexible bronchoscopy. PMID:18448507

    Three adults with cystic fibrosis (one after lung transplantation) presented with fever, chest pain, and acute radiographic changes. The changes included a cavitary lesion of the lung, acute dense infiltrates, and lobar collapse. After failing conventional antibiotic therapy, the patients underwent flexible bronchoscopy. All had bronchial obstruction by a membrane that had completely occluded the bronchial orifice at the bifurcation of the bronchi. Therapeutic interventions ranged from continuing intravenous antibiotics, bronchoscopy-assisted perforation of the membrane by sharp instrumentation, and transthoracic needle-guided perforation of the membrane with subsequent stenting of the orifice. The patients recovered, but the posttransplant patient had recurrent membranous obstructions with multiple interventions. The cause and triggers of the process are unknown. Based on repeated observations of the evolution of the membranes, and histologic material from bronchoscopies, we propose a putative paradigm of the natural history of the process. We suggest that local stimuli generate a richly vascularized granulation polyp, which progresses in a "shutter-like" motion to form partial or completely obstructive membranes. The subsequent course depends on the vascular supply to the membrane. We also propose that similar processes may be the underlying pathologic events in some cases of lung abscess and necrotizing pneumonia. PMID:16358340

    This study was to re-evaluate inhalation injury as a prognostic factor in burn patients and to determine the factors that should be considered when refining the definition of inhalation injury. A total of 192 burn patients (152 men, 40 women; mean age, 46.1±13.8 years) who were suspected to have an inhalation injury and underwent bronchoscopy between January 2010 and June 2012 were included in this prospective observational study. All patients underwent bronchoscopy within 24h of sustaining the burn. The bronchoscopic findings were classified as normal, mild, moderate, and severe. Mechanical ventilation was administered, when required. Age, percentage of TBSA burned, ABSI score, requirement of mechanical ventilation and PF ratio, but not inhalation injury, COHb level, and bronchoscopic grades, significantly differed between the survivors and non-survivors (pburns. Other components such as severity of inhalation injury determined using bronchoscopy, and administration of mechanical ventilation might help predict the morbidity and mortality of burn patients with inhalation injury and all of the factors should be considered when the definition of inhalation injury is refined.

Time consumption and logistics are two essential aspects that need to be optimized when integrating such technologies in the interventional room. We compared three different approaches to obtain airway centerlines and surface.CT lung dataset of 17 patients were processed in Mimics (Materialize, Leuven, Belgium, which provides a Basic module and a Pulmonology module (beta version (MPM, OsiriX (Pixmeo, Geneva, Switzerland and our Tube Segmentation Framework (TSF method. Both MPM and TSF were evaluated with reference segmentation. Automatic and manual settings allowed us to segment the airways and obtain 3D models as well as the centrelines in all datasets. We compared the different procedures by user interactions such as number of clicks needed to process the data and quantitative measures concerning the quality of the segmentation and centrelines such as total length of the branches, number of branches, number of generations, and volume of the 3D model.The TSF method was the most automatic, while the Mimics Pulmonology Module (MPM and the Mimics Basic Module (MBM resulted in the highest number of branches. MPM is the software which demands the least number of clicks to process the data. We found that the freely available OsiriX was less accurate compared to the other methods regarding segmentation results. However, the TSF method provided results fastest regarding number of clicks. The MPM was able to find the highest number of branches and generations. On the other hand, the TSF is fully automatic and it provides the user with both segmentation of the airways and the

    We report the successful use of the Air-Q laryngeal airway (Air-Q LA) as a ventilatory device and a conduit for tracheal intubation to rescue the airway in a patient with difficult airway and tracheal stenosis. This is the first case report of the device to secure the airway after two episodes of hypoxemia in the operating room and intensive care unit. Consent for submission of this case report was obtained from our institution's human studies institutional review board given that the patient died a few months after his discharge from the hospital before his personal consent could be obtained and before preparation of this report. All personal identifiers that could lead to his identification have been removed from this report. A 59-year-old man was scheduled for a flexible and rigid bronchoscopy with possible laser excision of tracheal stenosis. He had a history of hypertension, atrial fibrillation, and diabetes. Assessment of airway revealed a thyromental distance of 6.5 cm, Mallampati class II, and body weight of 110 kg. He had hoarseness and audible inspiratory/expiratory stridor with Spo2 90% breathing room air. After induction and muscle relaxation, tracheal intubation and flexible bronchoscopy were achieved without incident. The patient was then extubated and a rigid bronchoscopy was attempted but failed with Spo2 dropping to 92%; rocuronium 60 mg was given, and reintubation was accomplished with a 7.5-mm endotracheal tube. A second rigid bronchoscopy attempt failed, with Spo2 dropping to 63%. Subsequent direct laryngoscopy revealed a bloody hypopharynx. A size 4.5 Air-Q LA was placed successfully and confirmed with capnography, and Spo2 returned to 100%. The airway was suctioned through the Air-Q LA device, and the airway was secured using a fiberoptic bronchoscope to place an endotracheal tube of 7.5-mm internal diameter. The case was canceled because of edema of the upper airway from multiple attempts with rigid bronchoscopy. The patient was transported

    CASE DESCRIPTION A 17-month-old sexually intact male Vizsla and a 2-year-old spayed female mixed-breed dog were examined because of suspected intrathoracic grass awn migration. CLINICAL FINDINGS Thoracic CT revealed focal areas of pulmonary infiltration in the right caudal lung lobe in one dog and in the left caudal lung lobe in the other. In 1 patient, bronchoscopy revealed 2 grass awns in the bronchi. Results of thoracic radiography and bronchoscopy were unremarkable in the second patient; however, a grass awn was recovered from the tonsillar crypt during oropharyngeal examination. TREATMENT AND OUTCOME In both dogs, grass awns were successfully retrieved from the pleural cavity by means of video-assisted thoracic surgery during 1-lung ventilation. In one patient, a grass awn was recovered bronchoscopically from the left caudal lung lobe bronchus and another was visualized distally in an accessory lung lobe bronchus but could not be retrieved. This dog underwent accessory lung lobectomy. The second dog underwent left caudal lung lobectomy. Both patients recovered uneventfully from surgery, were discharged from the hospital, and had no apparent recurrence of clinical signs at telephone follow-up 31 months and 18 months after surgery. CLINICAL RELEVANCE With careful case selection, successful management of intrathoracic grass awn migration in dogs can be achieved by means of video-assisted thoracic surgery. Comprehensive preoperative evaluation including both computed tomography and bronchoscopy is suggested. Further investigation is necessary to evaluate whether treatment of this condition with video-assisted thoracic surgery is as effective as with traditional open thoracotomy. PMID:27379598

  18. Foreign body aspiration in children: clinical aspects, radiological aspects and bronchoscopic treatment

    International Nuclear Information System (INIS)

    Objective: To describe the clinical manifestations and bronchoscopic treatment of foreign body aspiration in children under 14 years of age, correlating the clinical aspects with the bronchoscopic findings. Methods: A retrospective, descriptive study analyzing data related to children under 14 years of age undergoing bronchoscopy due to clinical suspicion of foreign body aspiration at the State University at Campinas Hospital das Clinicas from January of 2000 to December of 2005. Results: The sample consisted of 69 patients, ranging in age from 8 months to 12 years/7 months (75.4% under 3 years of age), 62.3% of whom were male. The principal complaint was sudden-onset cough (75.4%), auscultation was abnormal in 74%, and dyspnea was observed in 29%. Radiological abnormalities were seen in 88% of the cases. Aspirations were primarily into the right lung (54.8%), and 30.7% of the foreign bodies were of vegetal origin (principally beans and peanuts). In the follow-up period, 29% presented complications (most commonly pneumonia), which were found to be associated with longer aspiration time (p = 0.03). Mechanical ventilation was required in 7 children (10.1%), and multiple bronchoscopies were performed in 5 (7.2%). Conclusions: A history of sudden-onset choking and cough, plus abnormal auscultation and radiological findings, characterizes the profile of foreign body aspiration. In such cases, bronchoscopy is indicated. Longer aspiration time translates to a higher risk of complications. The high prevalence of foreign bodies of vegetal origin underscores the relevance of prevention at children younger than three years of age. (author)

    Introduction: The diagnostic value of bronchoscopy for peripheral pulmonary lesions (PPLs) has improved since the application of radial endobronchial ultrasound (R-EBUS). Though R-EBUS indicates the position of the PPL, there is often a discrepancy between the obtained R-EBUS image and the diagnostic outcome. Meanwhile, probe based confocal laser endomicroscopy (pCLE) is a novel technique which provides in vivo real-time image of the contacted surface structures. However, its findings have not been established yet. Methods: Consecutive patients who have underwent bronchoscopy for PPLs were prospectively enrolled. R-EBUS with a guide sheath (GS) was inserted to the target PPL under X-ray fluoroscopic guidance. When an adequate R-EBUS image (within or adjacent to) was obtained, pCLE was sequentially inserted through the GS. Then pCLE image was scanned and biopsy was performed where an abnormal finding was estimated. The pCLE findings of PPLs and the background were recorded and analyzed exploratorily. Results: We analyzed 19 cases that we could get appropriate tissues. In all cases, bronchial walls showed longitudinal elastic fibers whereas alveolar walls formed grid-like elastic fiber networks. Conversely, discontinuous, crushed or aggregated alveolar structures accompanied by thickened and distorted fibers were detected in PPLs. Some cases showed dark hollow with fragmented or granular fluorescence. On the other hand, 11 cases (57.9%) indicated normal elastic fibers and needed the position change (3 cases; approached other bronchus, 6 cases; adjusted the position, 2 cases; penetrated the covered bronchial wall). Conclusion: The pCLE has a potential to improve the efficacy of diagnostic bronchoscopy for PPLs.

  1. Expandable metallic stents in the palliative treatment of malignant tracheobronchial stenosis

    International Nuclear Information System (INIS)

    The purpose of this study is to report the outcome of using expandable metallic stent in the management of malignant tracheobronchial stenosis with dyspnea. Under fluoroscopic and bronchoscopic guidance, seven patients with malignant airway stenosis were treated with ten expandable metallic stents. The cause of stenosis was metastasis from esophageal cancer in five patients, recurrent adenoid cystic carcinoma of the trachea in one, and primary lung cancer in one. The major sites of obstruction were the trachea in four patients, the left main bronchus in one, the trachea and left main bronchus in one, and the trachea and both bronchi in one. Chest radiography (n=7), bronchoscopy (n=5), pulmonary function test (PFT)(n=3), and spirometry(n=1) were performed before and after stent placement. In all seven patients, the stent was successfully placed at the lesion sites and dyspnea began to improve immediately. After the procedure, chest radiography and bronchoscopy showed an increase in airway diameter. After the procedure, chest radiography and bronchoscopy showed an increase in airway diameter. After stent placement, forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) improved 53% and 56%, respectively. Peak flow velocity also changed from 46 L/min to 200 L/min. During median follow-up of 67 (41-1565) days, one stent migration occurred. In one patient, proximal tumor overgrowth occurred, and in one, tumor ingrowth was treated with balloon dilatation. For in the palliative treatment of malignant tracheobronchial stenosis with dyspnea, placement of expandable metal stents is safe and effective. (author). 21 refs., 1 tabs., 3 figs

    Allergic bronchopulmonary aspergillosis (ABPA) is primarily a disease of patients with cystic fibrosis or asthma, who typically present with bronchial obstruction, fever, malaise, and expectoration of mucus plugs. We report a case of a young man with a history of asthma who presented with cough, left-sided pleuritic chest pain and was found to have lobar atelectasis and an eosinophilic, empyematous pleural effusion. Bronchoscopy and sputum cultures grew Aspergillus fumigatus, and testing confirmed strong allergic response to this mold, all consistent with a diagnosis of ABPA. This novel and unique presentation of ABPA expands on the differential diagnosis of eosinophilic pleural effusions. PMID:21311176

    Endobronchial tuberculosis is defined as a tuberculous infection of the tracheobronchial tree and has a prevalence of up to 50% in active pulmonary tuberculosis cases. The most common complication of endobronchial tuberculosis is bronchial stenosis; benign fistula formation by endobronchial tuberculosis is rare, especially inter-bronchial fistula formation. We reported a rare case of a 73-year-old woman with a fistula between the right upper bronchus and bronchus intermedius. A diagnosis of inter-bronchial fistula caused by endobronchial tuberculosis was based on the results of chest computed tomography scans, bronchoscopy, and microbiological and pathological tests. The patient was treated with anti-tuberculous medication, and her symptoms gradually improved.

    The aim of this pictorial essay was to present the main computed tomography findings seen in diffuse diseases of the trachea. The diseases studied included amyloidosis, tracheobronchopathia osteochondroplastica, tracheobronchomegaly, laryngotracheobronchial papillomatosis, lymphoma, neurofibromatosis, relapsing polychondritis, Wegener's granulomatosis, tuberculosis, paracoccidioidomycosis, and tracheobronchomalacia. The most common computed tomography finding was thickening of the walls of the trachea, with or without nodules, parietal calcifications, or involvement of the posterior wall. Although computed tomography allows the detection and characterization of diseases of the central airways, and the correlation with clinical data reduces the diagnostic possibilities, bronchoscopy with biopsy remains the most useful procedure for the diagnosis of diffuse lesions of the trachea.

    Full Text Available We report a case of pulmonary zygomycosis in an adult male diabetic patient who presented with fever and altered sensorium initially and later developed streaky haemoptysis. Bronchoscopy showed picture of necrotizing pneumonia. Sputum was negative for fungal elements on admission but later bronchial wash and repeat sputum samples were positive by microscopy and culture showed growth of Rhizopus species. Immediately the patient was put on amphotericin B but had a bout of massive haemoptysis and succumbed. A high index of suspicion is needed for an early diagnosis and aggressive treatment of this infection in view of the high mortality rate.

    Transbronchial needle aspiration(TBNA) is able to provide definitive answers for a wide variety of pulmonary benign and malignant diseases including infectious diseases,cystic lesions, granulomatous diseases, pulmonary and mediastinal mass, etc. It's proved particularly revolutionary to stage bronchogenic carcinoma during routine flexible bronchoscopy. What's more, TBNA is an extremely safe procedure with no reported major complications. This review introduces the techniques about identifying the target, obtaining the specimen and preparing and interpreting the specimen when conducting TBNA. The complications, a through unusual, and major limitations are also touched in this review.

    Full Text Available We describe a patient with long-standing ankylosing spondylitis who underwent percutaneous nephrolithotomy under spinal anesthesia. At preoperative assessment, it was considered that intubation of the trachea was likely to be difficult. Fiberoptic bronchoscopy was attempted, but without success. As the standard technique for spinal anesthesia failed, a variation of the paramedian approach in the lumbosacral approach, also known as Taylor′s approach was successfully attempted. This resulted in adequate sensory and motor blockade for the surgical procedure. The patient did not require airway interventions, but equipment and aids to secure airway were available.

    A 22-year-old male with recurrent periods of coughing and nasal discharge was unable to work and cooperate. A bronchoscopy revealed high amounts of leucocytes and no eosinofils, acute inflammation and > 105/ml Streptococcus pneumoniae susceptible to penicillin. The symptoms relapsed after penicillin and at the age of 24 the patient was CT-scanned which revealed bilateral sinusitis, mastoiditis and bronchiectasis. Treatment with azithromycin and a weight loss programme (from 156 kg) improved the health of the patient, who was an orangutan. This highlights the benefit of cooperation between medical doctors and veterinarians.

    Full Text Available Abstract Background Cough is the most common symptom presenting to doctors. The quality of cough (productive or wet vs dry is used clinically as well as in epidemiology and clinical research. There is however no data on the validity of cough quality descriptors. The study aims were to compare (1 cough quality (wet/dry and brassy/non-brassy to bronchoscopic findings of secretions and tracheomalacia respectively and, (2 parent's vs clinician's evaluation of the cough quality (wet/dry. Methods Cough quality of children (without a known underlying respiratory disease undergoing elective bronchoscopy was independently evaluated by clinicians and parents. A 'blinded' clinician scored the secretions seen at bronchoscopy on pre-determined criteria and graded (1 to 6. Kappa (K statistics was used for agreement, and inter-rater and intra-rater agreement examined on digitally recorded cough. A receiver operating characteristic (ROC curve was used to determine if cough quality related to amount of airway secretions present at bronchoscopy. Results Median age of the 106 children (62 boys, 44 girls enrolled was 2.6 years (IQR 5.7. Parent's assessment of cough quality (wet/dry agreed with clinicians' (K = 0.75, 95%CI 0.58–0.93. When compared to bronchoscopy (bronchoscopic secretion grade 4, clinicians' cough assessment had the highest sensitivity (0.75 and specificity (0.79 and were marginally better than parent(s. The area under the ROC curve was 0.85 (95%CI 0.77–0.92. Intra-observer (K = 1.0 and inter-clinician agreement for wet/dry cough (K = 0.88, 95%CI 0.82–0.94 was very good.

Patients and methods: The clinical data of 17 geriatric patients with foreign-body aspiration were retrospectively analyzed and compared with 26 nongeriatric adult patients. The data were collected from Peking University First Hospital and Anhui Chest Hospital between January 2000 and June 2014.Results: (1 In the geriatric group, the most common symptoms were cough and sputum (15 cases, 88%, dyspnea (six cases, 35%, and hemoptysis (four cases, 24%. Five patients (29% in the geriatric group could supply the history of aspiration on their first visit to doctor, a smaller percentage than in the nongeriatric group (13 cases, 50%. Only three cases in the geriatric group were diagnosed definitely without delay. Another 14 cases were misdiagnosed as pneumonia or lung cancer, and the time of delayed diagnosis ranged from 1 month to 3 years. Complications due to delay in diagnosis included obstructive pneumonitis, atelectasis, lung abscess, and pleural effusion. (2 Chest computed tomography demonstrated the foreign body in three cases (21% in the geriatric group, which was lower than the positive proportion of detection in the nongeriatric group (nine cases, 35%. The most common type of foreign body in the geriatric group was food, such as bone fragments (seven cases, 41% and plants (seven cases, 41%, and the foreign body was most often lodged in the right bronchus tree (eleven cases, 65%, especially the right lower bronchus (seven cases, 41%.

    A 29-year-old man underwent bilateral lung transplantation and received maintenance immunosuppressive therapy. He was readmitted 11 months later with symptoms of cough, sneezing, and rhinorrhea. The physical examination was normal. Laboratory results were significant for a reduction of FEV1 and an interstitial infiltrate on chest films. The patient had recently undergone bronchoscopy for rejection surveillance, and 2 days before admission the bronchoalveolar lavage cultures returned positive for respiratory syncytial virus. The patient was treated with aerosolized ribavirin with complete resolution of symptoms. Respiratory syncytial virus must now be included in the list of pathogens causing pneumonia in the lung transplant recipient. PMID:1540615

    A 49-year-old man was admitted for the evaluation of a bilateral mass shadow in his chest X-ray film. No definitive diagnosis was established either by brushing cytology or biopsy through bronchoscopy. No malignancies were suggested by general work-up. Both masses were surgically removed, and were diagnosed as pulmonary hyalinizing granuloma (PHG). Fifteen months later, low grade fever continued and the renal function decreased. Laboratory examinations revealed bilateral hydronephrosis with polyclonal hypergammaglobulinemia. The findings of abdominal CT and urography were compatible with retroperitoneal fibrosis. Steroid treatment completely reversed the initial abnormality in laboratory data and the symptoms disappeared. PMID:12135180

    Full Text Available A 42 year old African-American man from Indianapolis presented with cough and skin lesions. ACE level was elevated at 86 μg/L. Spirometry was normal except for a diffusing capacity 52% of predicted. Imaging was suggestive of sarcoidosis versus granulomatous infection. Bronchoscopy with bronchoalveolar lavage cytospin revealed a lymphocytic alveolitis (27% lymphocytes with a CD4:CD8 ratio of 6.2:1 by flow cytometry. Biopsy showed classic noncaseating granulomas and no organisms supporting the diagnosis of sarcoidosis. The patient’s symptoms and radiographic findings improved with 20 mg prednisone every other day for 3 months duration.

    We describe an immunocompetent child with bronchial fungus following foreign body aspiration. A two-year-old male presented with cough. Workup revealed air trapping and bronchoscopy showed aspirated foreign material in the right mainstem bronchus. Histopathology revealed fungal organisms suggestive of Aspergillus within an ulcer of the adjacent bronchial mucosa. Foreign body aspiration has been posited as a nidus for aspergilloma formation but is not yet described in the available English-language pediatric literature. Here, the foreign body provided a site for fungal growth in the bronchus of an otherwise healthy child. This case suggests that bronchial foreign body may pose risk of fungal colonization even in immunocompetent children.

    To evaluate polymerase chain reaction (PCR) for detection of Pneumocystis carinii, 117 bronchoalveolar lavage (BAL) specimens, from HIV-infected patients undergoing a diagnostic bronchoscopy, were processed and a nested PCR, followed by Southern blot and hybridization with a P32-labelled probe......, but sensitivity dropped markedly with this system. A further 33 patients had both induced sputum and bronchoalveolar lavage performed and the induced sputum was analysed using PCR and routine microbiological methods. The PCR sensitivity on induced sputum was equal to that of routine methods. At present...... the evaluated PCR cannot replace routine microbiological methods for detection of Pneumocystis carinii, on either BAL fluid or induced sputum....

  5. Clinical value of radiological methods in evaluation and therapy of severe thoracic trauma

    International Nuclear Information System (INIS)

    Plain chest radiographs allow the diagnosis of most intrathoracic injuries. However, they are only momentary pictures and give no information on the respiratory function. A tension pneumothorax, rib fractures and subcutaneous emphysema should be diagnosed clinically before radiographs are taken. Computed tomography is helpful in evaluation of intrapulmonary lesions, hemothorax, rupture of the diaphragm and dislocation of the heart. Further diagnostic tools include aortography in suspected aortic rupture, sonography in cardiac injuries and hemopericardium, bronchoscopy in suspected bronchial or tracheal rupture, ECG and enzyme determinations in cardiac contusion, and eventually pneumoperitoneum in suspected rupture of the diaphragm.

    Full Text Available A 28-year-old female patient was referred to us with complaints of massive haemoptysis and cough with expectoration, of two years′ duration. Her chest radiograph, computed tomography scan and video-bronchoscopy revealed a cystic lesion in the right upper and lower zones of the lungs. Aspiration from the cyst fluid was grossly hemorrhagic and full of inflammatory cells. On digestion of the fluid with potassium hydroxide, it showed plenty of hooklets and scolices of Echinococcus granulosus . An intact brood capsule was also seen. Diagnosis of hydatidosis was further confirmed by a positive serological and therapeutic response to albendazole.

  7. Successful Bronchoscopic Cryorecanalization in a Case of Endobronchial Lipoma

    2011-01-01

    Full Text Available Endobronchial lipomas are rare benign tumors; less than 150 cases have been reported so far. Bronchial occlusion usually leads to a misdiagnosis of asthma/COPD or malignancy. We report the case of a 67-year-old man with a history of heavy smoking (100 pack years, dyspnea on exertion, cough, and malaise who was treated for pneumonia for three weeks. Due to nonresolving atelectasis of the superior segment of the right lower lobe, a malignant endobronchial tumor was suspected. Rigid bronchoscopy with cryorecanalization led to both the definite histopathological diagnosis of endobronchial lipoma and the reopening of an endoluminal airway obstruction during one procedure.

    The diagnostic value of the CD4 cell counts and the HIV p24 antigen were evaluated in a consecutive series of 105 HIV-infected patients experiencing 128 episodes of pulmonary symptoms which required bronchoscopy. One-third of patients with opportunistic infection (OI) had CD4 counts greater than 0....... In conclusion, the CD4 cell counts and the presence of p24 antigen in serum had a very limited predictive value for the presence of OI in HIV-infected patients with pulmonary symptoms....

    Full Text Available The tracheo-esophageal fistula without esophageal atresia is a rare type esophageal malformation. It has a multifactorial etiology including environmental and genetic factors. Common clinical manifestations are coughing and choking after meals, cyanosis and/or recurrent pneumonia. Diagnosis requires a high clinical suspicion index. Fistula confirmation is done with imaging studies including upper digestive series, video-fluoroscopy or with the use of bronchoscopy wich allows direct visualization of the fistula or methylene blue passage through the abnormal communication. Fistula closure can be done endoscopically or surgically, in both cases with good results.

  10. Bronchial mucoepidermoid tumour in a child presenting with organomegaly due to secondary amyloidosis: case report and review of the literature

    International Nuclear Information System (INIS)

    Childhood bronchial mucoepidermoid tumours (BMET) are rare. A 12-year-old boy with hepatosplenomegaly underwent liver biopsy which diagnosed amyloidosis. Chest radiograph and CT, performed for recurrent respiratory symptoms, identified a left lower lobe tumour, which was subsequently excised. Histology showed a BMET. A literature review reveals 51 reported cases of BMET in children. Common presenting symptoms include fever, cough and recurrent pneumonia. Diagnosis is often delayed and patients with recurrent respiratory symptoms should undergo CT or bronchoscopy. The association between amyloidosis and BMET in this case is unique and has not been previously described, but may be coincidental. (orig.)

    2015-01-01

    Full Text Available Endobronchial tuberculosis (EBTB is an inflammation of the bronchial walls caused by tuberculous infection. The clinical, radiologic, and bronchoscopic presentation of EBTB is nonspecific and can be easily confused with other common pulmonary disorders. Its diagnosis requires isolation of Mycobacterium tuberculosis from bronchoscopic material. A high index of awareness of this entity and the early bronchoscopy in suspected patients are the cornerstones for establishing the diagnosis. The disease can occur in patients of all ages although it is more common in younger age group with a slight female preponderance. In recent years, a higher incidence has been reported in patients with human immunodeficiency virus infection.

    A 12-week-old infant girl born at 27 weeks gestation, with multiple comorbidities, was referred to the paediatric otolaryngology team due to stridor and feeding difficulties. Initial airway endoscopy was performed, showing no abnormal findings. The infant underwent frequent hospitalisations for recurrent cyanotic spells. Despite initial laryngoscopy and bronchoscopy not showing abnormalities, a repeat endoscopy demonstrated laryngomalacia, significant enough to require a supraglottoplasty. This is the first report to confirm, with video evidence, that some cases of laryngomalacia are acquired rather than congenital, even in infancy. PMID:26628452

    Military hospital of Plesetsk Cosmodrome was founded on 20 December 1958. The aims of the hospital were always connected with medical support of the cosmodrome, including emergency situations. On 18 March 1980 a Vostok-2M rocket exploded on its launch pad during a fuelling operation. Experience of medical assistance under conditions of large patient load showed the necessity of constant readiness to medical assistance to patients with combined pathology (burn injury, orthopedic trauma and thermochemical injury of the upper respiratory tract), expediency of compact patient accommodation along with the modern anaesthetic machine and readiness to frequent suction bronchoscopy.

    Gastric cancer frequently presents intraperitoneal spread. Distant metastasis are rare. The authors describe a case of a 47-year-old white man, long-term cigarette smoker, who had a right upper lobe mass seen on plain films and computed tomography of the chest. A gastric adenocarcinoma was concomitantly diagnosed by endoscopic examination. A bronchoscopy guided biopsy showed that the lung mass was in fact a metastasis from gastric adenocarcinoma. In this article, the imaging findings of gastric cancer and the patterns of dissemination to other organs are reviewed. (author)

    Full Text Available Pneumomediastinum (PM is defined as the presence of gas or free air in mediastinum. Pneumomediastinum may ocur either by trauma or spontaneously. Traumatic PM is frequently seen after blunt thoracic trauma, head trauma, after endoscopy-bronchoscopy (osephagus perforation, tracheobronchial injury and due to mechanical ventilation. Pneumomediastinum after blunt trauma is a lethal injury that generally occurs in adults with concomittant injuries such as rib fractures, hemo-pneumothorax and thoracic vascular injuries after high-energy traumas. We represent case report of a late onset isolated traumatic PM in a child and aim to underline the difficulty and importance of diagnosis of this lethal injury in the emergency department.

    Although tracheostomy is a well-accepted procedure for airway management, some early and late complications may occur. Fracture of the tracheostomy tube (TT) is a rare complication, particularly in a patient with long-term use. Herein we report a case of fractured metallic TT migrating into the tracheobronchial tree. Rigid bronchoscopy was performed through the tracheostomy stoma and the fractured tube was successfully removed by a balloon catheter. Appropriate cleaning, routine careful examination, and scheduled replacement of the TT may help prevent this complication. PMID:27489759

    The aim of the study was to evaluate the efficacy of cough-preventing treatment with levodropropizine, a drug inhibiting peripheral cough reflexes, in patients undergoing bronchial endoscopy. Sixteen patients, aged 37-73 years, suffering from chronic obstructive lung disease in the hypersecretory phase, were included in the study. The experiment was designed as double blind with double observer, controlled versus placebo. As comparative efficacy parameters were considered the number of anaesthetic boluses (lidocaine at 2%) administered during and immediately after the manoeuvre. The number of coughs during and 10 min after bronchoscopy was registered on a magnetic tape and read by a blinded observer thereafter. Levodropropizine was given as oral drops (20 each time, equal to 60 mg active drug) 12 h and 1 h before bronchoscopy. Data analysis was performed by descriptive statistical tests and by the non-parametric Wilcoxon test for paired samples. Levodropropizine treatment significantly reduced the number of anaesthetic enemas (p less than 0.01), and presented an excellent tolerability and safety profile.

    Full Text Available In spite the emergence of potent and broad spectrum antibiotics and recent advances in bronchoscopy and pulmonary physiotherapy, still there is a high rate of morbidity and mortality because of lung abscess. The objective of this study is the indication of risk factors, which have undesirable effects on the prognosis of lung abscess. In a retrospective study, all cases of lung abscess who was confined to bed during 1994 to 1999 in Rasht were collected and analyzed. From 52 cases, 40 (77% were male and 12 (23% were female. The mean duration of stay was 20 day (15 to 35. The secondary cause for lung abscess was as follows: 10 cases (19% COPD, 10 cases (19% preumonia, 15 cases (29% bronchiectasia 2 cases lung cancer, 2 cases lung hydatid cyst and 3 cases atelectasia. Extrapulmonary causes of lung abscess were consist of: 10 case (10% aspiration, 10 case (19% esophageal diseases tending to reflux, 5 case (9% periodontal disease. The factors, which had underiable effects on prognosis of disease were lung cancer, anemia, hypoalbuminemia, age over 60, abscess with pseudomonas, abscess cavity greater thus 8 cm, lower lobe in right lung and TB. Because of high mortality and morbidity of lung abscess, due attention for internal drainage, bronchoscopy, physiotherapy and timed surgery are seriously indicated.

    The aim of this study is to report our experience in the diagnosis and treatment of tracheobronchial foreign bodies (TFBs). We retrospectively reviewed medical records of 2,000 TFB patients (1,260 males and 740 females) who were treated between January 2010 and December 2013. Chest radiography and computed tomography were performed to diagnose TFBs. The location and type of foreign bodies (FBs), anesthesia methods, and treatment outcomes and complications were analyzed. Overall, 72.5% of our patients with TFB were aged between 1 years and 3 years. Plant-based FBs are the most common FB type, accounting for 91.5%. Almost 52.1% of the FBs were encountered in the right bronchus. The coincidence rate for computed tomography-based three-dimensional reconstruction was significantly greater than that for chest X-ray examination (98.7% vs 82.0%, P<0.01). Under general anesthesia, the FBs were removed by rigid bronchoscopy. Neither anesthesia complication nor intraoperative hypoxemia occurred. There were seven deaths from acute obstructive asphyxia and eight from residual FB-induced chronic asphyxia and respiration-circulation failure. In conclusion, early diagnosis and prompt treatment of TFBs with rigid bronchoscopy under general anesthesia is effective in reducing complications and mortality in affected children. PMID:26357477

    Full Text Available There were investigated 50 cytological preparations after fibro-optic bronchoscopy of 10 patients with cervical spinal cord injuries. The dynamics of broncho-pulmonary complications of spinal cord injuries was estimated on the basis of cytological broncho-alveolar lavage fluid investigations. In the work there were used clinico-neurologic methods, radiological (computer tomography and magnetic resonance imaging, endoscopic (fibro-optic bronchoscopy and cytomorphological investigations. Cytomorphological investigations of broncho-alveolar lavage fluid were carried out on the 3-4, 7, 14, 30th days. Cellular composition of the broncho-alveolar wash-out (endopulmonary cytogramme was estimated by calculation of more than 100 cells in 3 fields of the immersion microscope coverage. Quantitative changes of cellular elements were taken into account with respect to normal cell amount. The results were analyzed according to the average out method. Quantitative changes of inflammatory elements in endopulmonary cytogramme were determined by the degree of endobronchitic manifestations and were corresponding to clinico-radiological picture of development of broncho-pulmonary complications in different periods of spinal cord injury

    2006-08-15

    To evaluate the value of dose-reduced 16-slice multidetector-row spiral computed tomography (16-MDCT) using virtual tracheobronchoscopy (VTB) and virtual bronchography (VBG) in children with suspected tracheobronchial stenosis. 12 children (4 d to 3 years, body weight 1.2 kg to 13.5 kg) with stridor and suspected tracheobronchial stenosis were examined by contrast-enhanced low-dose 16-MDCT. Conventional axial slices, MPRs, VTB, and VBG were calculated. Image findings were correlated with the results of fiberoptic bronchoscopy (12 out of 12) as a gold standard and subsequent surgery (8 out of 12). VTB and VBG demonstrated the fiberoptic bronchoscopically suspected tracheal stenosis in 11 of 12 children due to vascular compression because of the brachiocephalic trunk (6), a double aortic arch (2), a vascular compression of the left main bronchus (2), and a right aberrant subclavian artery (1). Eleven out of 12 stenoses were correctly depicted by conventional axial slices, MPRs, VTB, and VBG. Dose reduction was 79 to 85.8% compared to a standard adult chest CT. Dose-reduced 16-MDCT with the use of VTB and VBG is effective for the evaluation of tracheobronchial stenosis in children and correlates well with fiberoptic bronchoscopy. (orig.)

  5. Contribution of interventional radiology to diagnosis and staging of bronchogenic carcinoma

    International Nuclear Information System (INIS)

    The value of percutaneous radiological fine needle biopsy of the thorax will be discussed in relation to sputum cytology, bronchoscopy, mediastinoscopy and open biopsy. Commun indications for fine needle biopsies are the solitary pulmonary nodule, unless it shows definite radiological criteria of a benign lesion, chest wall lesions including Pancoast tumors as well as pulmonary lesions, which were negative on bronchoscopy. Contraindications - in part relative - are coagulopathy, pulmonary arterial and venous hypertension, bullous emphysema, chronic obstructive pulmonary disease, diseases of the lung with an oxygen tension of less than 60 mm Hg and positive pressure mechanical ventilation. Fluoroscopy is the preferred method for localization. CT guidance is used for mediastinal and hilar lesions as well as for pulmonary lesions close to large vessels and for small lesions which are not clearly identified by fluoroscopy in two planes. The sensitivity of fine needle biopsy in the diagnosis of primary lung cancer was 87% in a total of 963 patients. The most common complication was pneumothorax which occurred in 27% of the biopsies guided by fluoroscopy and in 36% of those guided by CT. Catheter drainage of pneumothorax was performed in one third of these patients. Hemoptysis and local parenchymal hemorrhage were found in less than 5% and were without clinical consequence. In addition to technique, results and complications of percutaneous thoracic biopsies, methods of adrenal and liver biopsy in patients with carcinoma of the lung will be discussed. (Author)

    Plastic bronchitis is a rare cause of acute obstructive respiratory failure in children. Life-threatening events are much more frequent in patients with repaired cyanotic congenital heart disease, and most frequent following a Fontan operation. Commonly, the diagnosis is not made until bronchial casts are expectorated. Detailed CT findings in plastic bronchitis have not been described. To describe the CT findings in plastic bronchitis in children after a Fontan operation. Three children with plastic bronchitis after a Fontan operation were evaluated by chest CT. Bronchial casts were spontaneously expectorated and/or extracted by bronchoscopy. Airway and lung abnormalities seen on CT were analyzed in the three children. CT demonstrated bronchial casts in the central airways with associated atelectasis and consolidation in all children. The affected airways were completely or partially obstructed by the bronchial casts without associated bronchiectasis. The airway and lung abnormalities rapidly improved after removal of the bronchial casts. CT can identify airway and lung abnormalities in children with plastic bronchitis after a Fontan operation. In addition, CT can be used to guide bronchoscopy and to monitor treatment responses, and thereby may improve clinical outcomes. (orig.)

    The aim of the study was to evaluate the efficacy of cough-preventing treatment with levodropropizine, a drug inhibiting peripheral cough reflexes, in patients undergoing bronchial endoscopy. Sixteen patients, aged 37-73 years, suffering from chronic obstructive lung disease in the hypersecretory phase, were included in the study. The experiment was designed as double blind with double observer, controlled versus placebo. As comparative efficacy parameters were considered the number of anaesthetic boluses (lidocaine at 2%) administered during and immediately after the manoeuvre. The number of coughs during and 10 min after bronchoscopy was registered on a magnetic tape and read by a blinded observer thereafter. Levodropropizine was given as oral drops (20 each time, equal to 60 mg active drug) 12 h and 1 h before bronchoscopy. Data analysis was performed by descriptive statistical tests and by the non-parametric Wilcoxon test for paired samples. Levodropropizine treatment significantly reduced the number of anaesthetic enemas (p less than 0.01), and presented an excellent tolerability and safety profile. PMID:1794298

    The present study assessed the diagnostic usefulness of a multiplex PCR (mPCR) for Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae and Chlamydophila pneumoniae applied to bronchoalveolar lavage (BAL). Fibreoptic bronchoscopy was performed on 156 hospitalised adult patients with lower respiratory tract infection (LRTI) and 36 controls. BAL fluid was analysed with bacterial culture and mPCR. By conventional diagnostic methods, S. pneumoniae, H. influenzae, M. pneumoniae and C. pneumoniae were aetiological agents in 14, 21, 3.2 and 0% of the LRTI patients, respectively. These pathogens were identified by BAL mPCR in 28, 47, 3.2 and 0.6% of cases, respectively, yielding sensitivities of 86% for S. pneumoniae, 88% for H. influenzae, 100% for M. pneumoniae and 0% for C. pneumoniae, and specificities of 81, 64, 100 and 99% for S. pneumoniae, H. influenzae, M. pneumoniae and C. pneumoniae, respectively. Of the 103 patients who had taken antibiotics prior to bronchoscopy, S. pneumoniae was identified by culture in 2.9% and by mPCR in 31%. Among the controls, mPCR identified S. pneumoniae in 11% and H. influenzae in 39%. In lower respiratory tract infection patients, bronchoalveolar lavage multiplex PCR can be useful for identification of Streptococcus pneumoniae, Mycoplasma pneumoniae and Chlamydophila pneumoniae. The method appears to be particularly useful in patients treated with antibiotics.

    A review has been made of original articles on invasive pneumology techniques, interstitial diseases and lung transplantation, published in the Archivos de Bronconeumología during the year 2008. We have selected the publication by Martínez-Olondrins et al on the mediastinal staging of bronchogenic carcinoma by transbronchial needle aspiration to highlight the role of this simple, safe and cost-effective technique at a time when aspiration by ultrasound-guided bronchoscopy is profiled as an alternative to staging by mediastinoscopy. Besides its usefulness in the study of lymph nodes, transbronchial needle aspiration increases the overall performance of bronchoscopy by 20%, which means that it should be considered as a basic tool in the study of lung cancer. We also comment on the work by Galvis-Caravajal et al, who describe percutaneous radiofrequency as an alternative to radiotherapy in small lung or metastasic tumours. In diffuse interstitial disease, Morell et al analysed the diagnostic methods in 500 patients with this clinical-radiological presentation in which a definitive diagnosis was achieved in 85%, with 25% of them being obtained by non-invasively. Baloira et al analysed the characteristics of 19 patients with desquamative interstitial pneumonia and respiratory bronchiolitis associated-interstitial lung disease obtained from the National register of Interstitial Diseases.

    In closed chest trauma, bronchial rupture is an unusual but potentially serious complication, with an associated mortality rate of 30%. Recent decades have seen an increase in incidence parallel to greater use of transport. Eighty percent of injuries are located 2.5 cm from the carina. Diagnosis is based on clinical signs, imaging and bronchoscopy. Subcutaneous emphysema and respiratory insufficiency are the most common findings. Images show the presence of pneumothorax, pneumomediastinum or both. Bronchoscopy is the diagnostic method of choice and must be performed early. Treatment consists of reestablishing anatomical continuity of the tracheobronchial tree by surgical repair if the lesion affects more than a third of the circumference and/or pneumothorax is not resolved after two chest drainages. This type of injury should be recognized and treated early, both to restore lung function and to prevent associated complications caused by delay. However, initial findings are seldom specific, requiring the physician to display a high degree of suspicion and explaining why diagnosis often comes late. PMID:11171438

    Fibered confocal fluorescence microscopy (FCFM) is an emerging technique that can be used during bronchoscopy to analyze the nature of the human bronchial mucosa and alveolar network fluorescence microstructure. An endoscopic fibered confocal fluorescence microscopy system with spectroscopic analysis capability was developed allowing realtime, simultaneous images and emission spectra acquisition, at 488 nm excitation, using a flexible miniprobe. This flexible 1.4 mm miniprobe can be introduced into the working channel of a flexible endoscope and gently advanced through the bronchial tree up to the alveoli. FCFM in conjunction with bronchoscopy is able to image the in vivo autofluorescence microstructure of the bronchial mucosa but also the alveolar respiratory network outside of the usual field of view. In the normal bronchi, reproducible images were obtained, characterized by a highly organized fibered network. Precancerous lesions exhibited alterations of this fibered network. Microscopic and spectral analysis showed that the signal mainly originates from the elastin component of the bronchial subepithelial layer. In non smokers, the system images the elastin backbone of the aveoli. In active smokers, a strong autofluorescence signal appears from alveolar macrophages. The FCFM technique appears promising for in vivo exploration of the bronchial and alveolar extracellular matrix.

A 73 year-old woman, a lifetime non-smoker, presented to the pulmonary clinic with chronic dyspnea on exertion and cough. Physical exam was unremarkable and pulmonary function testing showed normal spirometry. A chest radiograph revealed calcified mediastinal adenopathy and increased density in the right middle lobe region (Figure 1. A computed tomography scan of the chest revealed significant narrowing of the right middle lobe bronchus with partial atelectasis and prominent calcified mediastinal lymphadenopathy (Figure 2. Bronchoscopy showed no endobronchial lesions but there was evidence of extrinsic compression surrounding the right middle lobe orifice. An endobronchial biopsy revealed noncaseating granulomas. Bronchoscopy cultures and cytology were negative and this was presumed to be from a previous infection with histoplasmosis given the patient’s long-term residence in an endemic area. Given chronic narrowing of right middle lobe bronchus with persistent atelectasis of the right middle lobe, the patient was diagnosed with right middle lobe syndrome. ...

    Full Text Available A 19-year-old Vietnamese lady was diagnosed with culture positive, left upper lobe pulmonary tuberculosis for which medical treatment was initiated. Four months into treatment, she developed a 'rubber-band-like' stretching sensation in her left chest with wheezing and shortness of breath. Decreased respiratory excursion over the left lung was present on physical-examination. Chest-Xray revealed left-upper-lobe collapse with leftward deviation of the trachea and mediastinum. CT thorax revealed a long segment of stenosis in the left mainstem bronchus. FEV1 was 1.26 L (45% predicted, FVC 1.53 L (49% predicted, FEV1/FVC 82% (95% predicted indicating airway limitation. Ventilation-perfusion scan noted 9.8% ventilation to the left lung and 92.8% to the right lung and 7.6% perfusion to the left lung and 92.4% to the right lung. Bronchoscopy was notable for pin point stenosis of the left mainstem bronchus beyond which was inflamed mucosa and abnormal cartilage rings in the left upper and middle lobe bronchi. Nine months of medical therapy for tuberculosis along with oral steroid taper was completed successfully; however the patient has required six serial bronchscopies with dilatations without stent placement at four to six week intervals due to partial restenosis, with the last bronchoscopy at four months after completion of tuberculosis therapy.

    Tracheal diverticulum (TD) defined as a typical benign out-pouching of the tracheal wall due to structural weakness, congenital or acquired in origin, resulting in paratracheal air cysts. It is rarely diagnosed in clinical practice with only limited reports in the literature. Most cases found incidentally in the postmortem examination and located on the right side. Uncomplicated TDs are usually asymptomatic and when symptoms have occurred, they usually present with non-specific symptoms like pharyngeal discomfort, cough, dyspnea, and recurrent respiratory infection due to either the compression of adjacent organs or secondary bacterial infection. Imaging techniques like thoraco-cervical multi-slice spiral computed tomography (CT) and fiber-optic bronchoscopy are important diagnostic tools for this entity. Asymptomatic TDs usually require no treatment and managed conservatively while surgical excision is indicated in cases of compression of adjacent organs and recurrent infections. Here we report a case of tracheal diverticulum on the left side, which was diagnosed as part of a work-up for chronic cough and recurrent chest infection in a 40 year old female who was already on bronchodilator without any relief. Diagnosis of TD was based on findings of computed tomography, revealing small bud like projection on left para tracheal region and further confirmed by fiber-optic bronchoscopy while the barium contrast study showed no esophageal communication. She was managed conservatively and referred for surgical excision. PMID:27266290

    The use of the Sanders venturi system during bronchoscopy in adults has been studied extensively. Its use in paediatric bronchoscopy has been limited because small changes in the characteristics of the system may produce large changes in the patient. With jet ventilation, peak inflation pressures and flow rates are influenced by the driving pressure, diameter and shape of the bronchoscope, the diameter of the injector and its length and angle from the axial line of the bronchoscope. Storz 3 mm, 4 mm and 5 mm rigid fibreoptic bronchoscopes were evaluated in a test lung with an injector of 1.5 mm internal diameter fixed in the side-arm at 20 degrees to the axial line. Pilling 3 mm, 4 mm and 5 mm rigid fibreoptic bronchoscopes were also examined using the standard injector with a 0.89 mm orifice in the axial line. The Storz bronchoscopes produced consistently higher peak inflation pressures and flow rates at all driving pressures in spite of the relatively large angle of the injector from the axial line. Caution is advised in the use of the Storz injector system as excessively high inflation pressures may be reached.

  19. Method for endobronchial video parsing

    Endoscopic examination of the lungs during bronchoscopy produces a considerable amount of endobronchial video. A physician uses the video stream as a guide to navigate the airway tree for various purposes such as general airway examinations, collecting tissue samples, or administering disease treatment. Aside from its intraoperative utility, the recorded video provides high-resolution detail of the airway mucosal surfaces and a record of the endoscopic procedure. Unfortunately, due to a lack of robust automatic video-analysis methods to summarize this immense data source, it is essentially discarded after the procedure. To address this problem, we present a fully-automatic method for parsing endobronchial video for the purpose of summarization. Endoscopic- shot segmentation is first performed to parse the video sequence into structurally similar groups according to a geometric model. Bronchoscope-motion analysis then identifies motion sequences performed during bronchoscopy and extracts relevant information. Finally, representative key frames are selected based on the derived motion information to present a drastically reduced summary of the processed video. The potential of our method is demonstrated on four endobronchial video sequences from both phantom and human data. Preliminary tests show that, on average, our method reduces the number of frames required to represent an input video sequence by approximately 96% and consistently selects salient key frames appropriately distributed throughout the video sequence, enabling quick and accurate post-operative review of the endoscopic examination.

    Background: Multidetector CT-angiography (MDCTA) is commonly used in patients with severe haemoptysis requiring admission to intensive care unit. However, the impact of MDCTA on the management of severe haemoptysis in emergency setting is poorly evaluated. Methods: We prospectively compared data provided by clinical bedside evaluation (clinical examination, chest-X-ray and fiberoptic bronchoscopy) to MDCTA data in terms of lateralization, location of the bleeding site, etiology as well as impact on the treatment choice. Results: Over a 13-month period, 87 patients (men n = 58, median age = 61 years, median haemoptysis expectorated volume = 180 mL) were included. Etiology was mainly (67%) bronchiectasis, tuberculosis sequelae and tumor. MDCTA and clinical bedside evaluation were equally effective in determining lateralization (87.4% and 93.1%, respectively, p = 0.23) and location (85% and 82.7%, respectively, p = 0.82) of the bleeding site. MDCTA was significantly more accurate than the clinical bedside strategy in determining the haemoptysis cause (86% and 70%, respectively, p = 0.007). Moreover, MDCTA suggested the involvement of systemic arteries as bleeding mechanism in 92% of cases, leading to the modification of the treatment initially considered after bedside evaluation in 21.8% of patients. Conclusion: MDCTA provides useful information for the management of patients with severe haemoptysis, especially in the treatment choice. Thus, in the absence of emergency fiberoptic bronchoscopy (FOB) requirement for airways management, MDCTA should be the first-line procedure performed in emergency clinical setting.

    Background: Ambient air pollution is associated with adverse health effects, but the sources and components, which cause these effects is still incompletely understood. The aim of this thesis was to investigate the pulmonary effects of a variety of common air pollutants, including diesel exhaust, biomass smoke, and road tunnel and subway station environments. Healthy non-smoking volunteers were exposed in random order to the specific air pollutants and air/control, during intermittent exercise, followed by bronchoscopy. Methods and results: In study I, exposures were performed with diesel exhaust (DE) generated at transient engine load and air for 1 hour with bronchoscopy at 6 hours post-exposure. Immunohistochemical analyses of bronchial mucosal biopsies showed that DE exposure significantly increased the endothelial adhesion molecule expression of p-selectin and VCAM-1, together with increased bronchoalveolar lavage (BAL) eosinophils. In study II, the subjects were exposed for 1 hour to DE generated during idling with bronchoscopy at 6 hours. The bronchial mucosal biopsies showed significant increases in neutrophils, mast cells and lymphocytes together with bronchial wash neutrophils. Additionally, DE exposure significantly increased the nuclear translocation of the aryl hydrocarbon receptor (AhR) and phosphorylated c-jun in the bronchial epithelium. In contrast, the phase II enzyme NAD(P)H-quinone oxidoreductase 1 (NQO1) decreased after DE. In study III, the 2-hour exposures took place in a road tunnel with bronchoscopy 14 hours later. The road tunnel exposure significantly increased the total numbers of lymphocytes and alveolar macrophages in BAL, whereas NK cell and CD56+/T cell numbers significantly decreased. Additionally, the nuclear expression of phosphorylated c-jun in the bronchial epithelium was significantly increased after road tunnel exposure. In study IV, the subjects were exposed to metal-rich particulate aerosol for 2 hours at a subway station

    Full Text Available INTRODUCTI ON: Foreign body aspiration in pediatrics is a potentially fatal accident which will continue until children explore their surroundings with their hand and mouth. Pediatric aspirations will persist until mankind exists. Not all foreign body aspirations are witnessed hence chances of delay in diagnosing an aspiration are high. Delay in diagnosis depends on site and character of foreign body aspirated. The chest x - ray findings and type of foreign body extracted vary depending on the duration the foreign body remains in airway . OBJECTIVE: To study the X - ray finding in pediatric airway aspiration and its relation to time lapse, the type and site of lodgment of foreign body extracted via bronchoscopy. The type of foreign body in relation to time lapse in aspiration. MATERIAL AND METHODS: This was a prospective study done in Bapuji child health institute and research center, JJM Medical College, Davangere . History and pre bronchoscopy x - Ray finding were noted for 65 children who were posted for suspicious bronchoscopy from August 2011 to September 2013. 11 children were excluded from study as they showed no foreign body on bronchoscopy. Time lapse in aspir ation and seeking medical care was noted. The bronchoscopic findings regarding site of foreign body lodgment and type of foreign body were recorded. The type of foreign body and variation of x - ray picture in relation to time lapse in aspiration were noted. Data collected was analyzed using descriptive statistics. RESULT: It was observed that mean age was 28 months. About 80% of the cases were between 1 to 3 years age. 82% (n=53/54 were radio lucent foreign body, only 1.5% (n=1/54 were radio o paque. Site of lodgment of foreign body was right main bronchus in 48% (n=26/54, left main bronchus 46% (n=25/54 , tracheal 1.85% (n=1/54, subglottic 1.85% (n=1/54, carinal 1.85% (n=1/54, multiple site i.e. left bronchus +right bronchus+ carinal 1.85% (n=1/54.

    Mediastinal aortic vascular anomalies are relatively common causes of extrinsic central airway narrowing in infants with respiratory symptoms. Surgical correction of mediastinal aortic vascular anomalies alone might not adequately treat airway symptoms if extrinsic narrowing is accompanied by intrinsic tracheomalacia (TM), a condition that escapes detection on routine end-inspiratory imaging. Paired inspiratory-expiratory multidetector CT (MDCT) has the potential to facilitate early diagnosis and timely management of TM in symptomatic infants with mediastinal aortic vascular anomalies. To assess the technical feasibility of paired inspiratory-expiratory MDCT for evaluating TM among symptomatic infants with mediastinal aortic vascular anomalies. The study group consisted of five consecutive symptomatic infants (four male, one female; mean age 4.1 months, age range 2 weeks to 6 months) with mediastinal aortic vascular anomalies who were referred for paired inspiratory-expiratory MDCT during a 22-month period. CT angiography was concurrently performed during the end-inspiration phase of the study. Two pediatric radiologists in consensus reviewed all CT images in a randomized and blinded fashion. The end-inspiration and end-expiration CT images were reviewed for the presence and severity of tracheal narrowing. TM was defined as {>=}50% reduction in tracheal cross-sectional luminal area between end-inspiration and end-expiration. The presence of TM was compared to the bronchoscopy results when available (n = 4). Paired inspiratory-expiratory MDCT was technically successful in all five patients. Mediastinal aortic vascular anomalies included a right aortic arch with an aberrant left subclavian artery (n = 2), innominate artery compression (n = 2), and a left aortic arch with an aberrant right subclavian artery (n = 1). Three (60%) of the five patients demonstrated focal TM at the level of mediastinal aortic vascular anomalies. The CT results were concordant with the

    After an analysis of the complex interweaving reactions of laser on biological materials, the laser applications in medicine and surgery are reviewed by the author. In ophthalmology its use is regular but not yet optimal. In otological applications the first results are good. In dermatology favorable results are obtained but the absence of special device had stopped his development. In surgery and endoscopy the best wave length must be chosen in reference to their hemostatic action and cutting, nevertheless in gastroscopy and bronchoscopy the laser seems to bring new therapeutic solutions. In odontology the pulsed lasers are dangerous for therapy but the holographic technique is a fertile research area. The author conclude to the necessary development of researches on the fundamental problems set by the biomedical applications of lasers.

    2014-01-01

    Full Text Available Context: There are no established guidelines for the proper treatment of patients with bronchopleural fistulas (BPFs. Apart from attempts to close the fistula, emphasis of treatment and management is placed on preventive measures, early administration of antibiotics, drainage of the empyema and aggressive nutritional and rehabilitative support. Case Report: A 53-year-old male presented with nausea, vomiting, and dry cough with eventual respiratory failure. He was found to have an empyema of the left hemithorax which was managed with thoracostomy drainage and antibiotics. However, he had persistent air leak through the chest tube due to a BPF. Bronchoscopy failed to localize the involved segment. Application of fibrin glue through the chest tube succeeded in completely sealing the leak. Conclusion: To our knowledge, this is the first case report in which fibrin glue was successfully used intrapleurally to close a BPF related to an empyema.

    Full Text Available Chest trauma is one of the important causes of mortality and morbidity in pediatric trauma patients. The complexity, magnitude, and type of lung injury make it extremely challenging to provide optimal oxygenation and ventilation while protecting the lung from further injury due to mechanical ventilation. Independent lung ventilation is used sporadically in these patients who do not respond to these conventional ventilatory strategies using double-lumen endotracheal tubes, bronchial blocker balloons, etc. However, this equipment may not be easily available in developing countries, especially for pediatric patients. Here, we present a case of severe chest trauma with pulmonary contusion, flail chest, and bronchopleural fistula, who did not respond to conventional lung protective strategies. She was successfully managed with bronchoscopy-guided unilateral placement of conventional endotracheal tube followed by single lung ventilation leading to resolution of a chest injury.

We evaluated 50 workers with BeS with medical and occupational histories, physical examination, chest imaging with HRCT (N=49), and pulmonary function testing. Forty of these workers also underwent bronchoscopy for bronchoalveolar lavage (BAL) and transbronchial biopsies. The mean duration of employment at the facility was 18 yrs and the mean latency (from first possible exposure) to time of evaluation was 32 yrs. Five of the workers had CBD at the time of evaluation (based on histology or HRCT); three others had evidence of probable CBD. These workers with BeS, characterized by a long duration of potential Be exposure and a long latency, had a low prevalence of CBD.

    Full Text Available We report a case of an elderly woman who developed a severe, chronic pulmonary reaction to nitrofurantoin therapy that she had taken continuously for three years to prevent urinary tract infections. The patient was taking no other drug known to cause lung disease but the diagnosis was delayed by failure to recognize the association between nitrofurantoin and adverse drug reactions affecting the lung. When originally seen, the patient was unable to care for herself due to dyspnea. Bronchoscopy with biopsy ruled out other causes of her pulmonary disease. Immediate withdrawal of nitrofurantoin led to substantial, sustained improvement and disappearance of symptoms over several months without administration of corticosteroids. Nitrofurantoin toxicity should always be considered in any person taking that drug who develops bilateral infiltrates.

    We present a case of a man in his late 60s, who had spent 3-4 months of the year in rural Spain, presenting with intermittent hoarseness of voice. He had a background of asthma and bronchiectasis, and was taking inhaled corticosteroids. His dysphonia was initially managed as bronchiectasis with little improvement. Bronchoscopy revealed a cystic lesion on his left vocal fold, and tissue biopsy revealed Leishmania amastigotes. This confirmed a diagnosis of laryngeal leishmaniasis. We propose that this is likely secondary to his inhaled corticosteroid therapy. The infection was treated with a 30-day course of miltefosine, and at most recent follow-up the patient was deemed free from leishmanial infection. PMID:27329097

    Full Text Available Plastic bronchitis (PB, although a rare cause of airway obstruction, has mortality rates up to 50% in children after Fontan-type cardiac surgery. We present the case of an 18-month-old female patient with PB following pneumonia. At 6 months of age, the patient underwent the Glenn procedure due to functionally univentricular heart. Fiberoptic bronchoscopy revealed complete blockage of the left bronchus by mucoid casts. Pharmacotherapy consisted of glucocorticosteroids, azithromycin, and enalapril maleate. The child also received nebulized 3% NaCl solution, which proved to be beneficial. In children submitted to Fontan-type procedures, physicians must be alert for PB, which can be triggered by respiratory tract infection.

    If a radiologist from 1950 could travel in time to 2011, he or she would be baffled to see how few of the radiological examinations he was familiar with, remain. We review the radiological examinations that have disappeared since X-rays were discovered, and include the causes of their disappearance. Barium studies have mainly been replaced by endoscopy, oral cholecystography by ultrasound, and intravenous urography by CT-scan. Angiography by means of a direct puncture of carotid artery and aorta has been replaced by Seldinger angiography. Pneumencephalography and myelography have been replaced by CT and MRI. Bronchography has been replaced by bronchoscopy and CT-scan, arthrography by MRI and arthroscopy. Many other radiological examinations have been replaced by ultrasound, CT or MRI. PMID:21447222

    2012-10-01

    We present a case of an elderly non-smoking gentleman who, since 2005, had been admitted multiple times for recurrent episodes of shortness of breath, wheeze, cough and sputum. The patient was treated as exacerbations of chronic obstructive pulmonary disease (COPD) and\\/or lower respiratory tract infections. Bronchoscopy was done which revealed multiple hard nodules in the trachea and bronchi with posterior tracheal wall sparing. Biopsies confirmed this as tracheopathia osteochondroplastica (TO). He had increasing frequency of admission due to methicillin-resistant Staphylococcus aureus and pseudomonas infections, which failed to clear despite intravenous, prolonged oral and nebulised antibiotics. The patient developed increasing respiratory distress and respiratory failure. The patient died peacefully in 2012. This case report highlights the typical pathological and radiological findings of TO and the pitfalls of misdiagnosing patients with recurrent chest infections as COPD.

    Antibody responses to a major purified human Pneumocystis carinii surface antigen (gp95) were determined by ELISA in human immunodeficiency virus (HIV)-infected patients. Serum IgG directed against gp95 was measured in 129 consecutive HIV-infected patients who underwent bronchoscopy for evaluation...... of pulmonary symptoms. Significantly more patients with P. carinii pneumonia (PCP) had detectable antibodies compared with HIV-infected patients without PCP and with HIV-negative controls (50 [66%] of 76 vs. 18 [34%] of 53 and 7 [35%] of 20, respectively; P less than .001), and the level of antibody response...... response, compared with only 1 (3%) of 31 patients without PCP (P less than .001). This patient had PCP on the basis of clinical criteria, including response to therapy. Thus, despite severe immunosuppression, a proportion of HIV-infected patients with PCP can mount a specific IgG-mediated antibody...

    2013-06-07

    Common variable immunodeficiency (CVID) is the most common of the primary immunodeficiency disorders. Pulmonary manifestations are characterised by recurrent rhinosinusitis, respiratory tract infections and bronchiectasis. Less commonly the lung may be affected by lymphoid disorders and sarcoid-like granulomas. Organising pneumonia (OP) is a rare pulmonary manifestation. We report the case of a 32-year-old woman with CVID who presented with fever, dyspnoea and persistent lung infiltrates despite antibiotic therapy. CT of the chest showed bilateral patchy alveolar infiltrates. Pulmonary function tests revealed moderate restriction and reduction in diffusion capacity. Initial bronchoscopy with transbronchial biopsies did not yield a diagnosis but surgical lung biopsies identified OP. Significant clinical, radiographic and physiological improvement was achieved after institution of corticosteroid therapy.

  17. Bronchography in patients with persistent cough

    International Nuclear Information System (INIS)

    Bronchography was performed together with a fibre-optic bronchoscopic study in 98 patients with persistent cough, 33 of whom also had haemoptysis. Finally there were chronic bronchitis in 62 patients, bronchiectasis in 21, subacute bronchitis in 9, inflammatory residuals in 3, pulmonary tuberculosis in 2 patients and metastases in one. In chronic bronchitis, the value of plain chest radiography was low. It was normal in 34 of 62 cases (55%), bronchography in 12 cases (19%). Mild cases of bronchitis were more numerous in bronchography than seen by scopist. Bronchiectasis was found in 21 patients, four of these unexpectedly (two in a tbc scar). Additionally, three cases were overdiagnosed by the radiologist on chest films and eight cases by the scopist with bronchoscopy. In patients with persistent cough and haemoptysis, bronchography mainly revealed alterations of bronchitis. (orig.)

    2016-01-01

    Full Text Available We report a rare case of esophageal lung in a neonate who presented with repeated chest infections and respiratory distress. Chest radiograph revealed increased opacification of the right lung with reduced lung volume and air bronchograms. Further evaluation with computed tomography (CT showed the presence of only left mainstem bronchus at the tracheal bifurcation. Right mainstem bronchus originated from distal esophagus and aerated the right lung. Nasogastric tube was inserted into the stomach with injection of small amount of dilute barium through it, which established the communication of right mainstem bronchus with esophagus. Advanced CT scan imaging by virtual bronchoscopy and volume rendering further delineated the anatomical abnormality precisely prior to surgery. Surgical findings confirmed the diagnosis.

  19. Pulmonary eosinophilia associated to treatment with natalizumab

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Natalizumab (Tysabri® is a leukocytes chemotaxis inhibitor that decreases the leukocytes passage through the hematoencephalic barrier and it is currently used in relapsing-remitting forms of multiple sclerosis (MS. We present a patient with allergic rhinoconjunctivitis diagnosed with MS who started treatment with natalizumab. She began to show mild asthmatic symptoms until she needed admission to the hospital due to respiratory insufficiency. Blood tests showed peripheral eosinophilia and the thoracic computed tomography scan demonstrated pulmonary infiltrates. The bronchoscopy with the bronchoalveolar lavage resulted in eosinophilic alveolitis. No evidence of bacterial, fungal and parasitic infection, connective tissue disease, or vasculitis were observed. After discontinuation of natalizumab, the patient improved without other treatments. As MS is a prevalent disease and the use of natalizumab is increasing, we consider important to point out that this drug can be associated with pulmonary eosinophilia, especially in patients with allergic rhinoconjunctivitis or asthma.

    The nasogastric tube (NGT) has become a frequently used device to alleviate gastrointestinal symptoms. Nasogastric tube syndrome (NTS) is an uncommon but potentially life-threatening complication of an indwelling NGT. NTS is characterized by acute upper airway obstruction due to bilateral vocal cord paralysis. We report a case of a 76-year-old man with NTS, induced by an indwelling long intestinal tube. He was admitted to our hospital for treatment of sigmoid colon cancer. He underwent sigmoidectomy to release a bowel obstruction, and had a long intestinal tube inserted to decompress the intestinal tract. He presented acute dyspnea following prolonged intestinal intubation, and bronchoscopy showed bilateral vocal cord paralysis. The NGT was removed immediately, and tracheotomy was performed. The patient was finally discharged in a fully recovered state. NTS be considered in patients complaining of acute upper airway obstruction, not only with a NGT inserted but also with a long intestinal tube. PMID:27099450

    2015-11-01

    Full Text Available A 65-year-old man with right central type of lung squamous carcinoma was admitted to our department. Bronchoscopy displayed complete obstruction of right upper lobe bronchus and infiltration of the bronchus intermedius with tumor. Chest contrast computed tomography revealed the tumor invaded right pulmonary artery, superior vena cava, and the persistant left superior vena cava flowed into the coronary sinus. The tumor was successfully removed by means of bronchial and pulmonary artery sleeve resection of the right upper and middle lobes combined with resection and reconstruction of superior vena cava (SVC utilizing ringed polytetrafluoroethylene graft. To the best of our knowledge, this was the first report of complete resection of locally advanced lung cancer involving superior vena cava, right pulmonary artery trunk and main bronchus with persistant left superior vena cava.

    Full Text Available Neurofibromatosis or von Recklinghausen's disease is the most common inherited syndrome predisposing to neoplasia. Carcinosarcoma is a rare malignant mixed tumor of the lung. Association of carcinosarcoma of lung with Neurofibromatosis-1 is not common. A 57-year-old man presented with history of fever, cough, hemoptysis, breathlessness, weight loss, chest pain. Multiple cutaneous neurofibromas and café au lait spots were revealed by physical examination. A homogeneous opacity was found in the right middle and right upper zone on posterior-anterior chest radiography. A 8x8x7 cm mass that had irregular borders in right upper posterior and apical segment was seen on contrast enhanced chest computed tomography. On bronchoscopy, the lumen of right upper apical segment was obstructed with vegetating tumoral lesion. The biopsy taken from this region was diagnosed as carcinosarcoma by histopathological and immunohistochemical examination.A rare case with carcinosarcoma of the lung and Neurofibromatosis-1 was reported.

    There is a need to develop noninvasive methods for the diagnosis of Pneumocystis carinii pneumonia in patients unable to undergo bronchoscopy or induction sputum. Oral wash specimens are easily obtained, and P. carinii nucleic acid can be amplified and demonstrated by PCR. In routine clinical use...... was compared to a previously described PCR protocol (mitochondrial RNA) run in a research laboratory. Both PCR methods amplified a sequence of the mitochondrial rRNA gene of P. carinii. Paired bronchoalveolar lavage (BAL) and oral wash specimens from 76 consecutive human immunodeficiency virus type 1...... wash specimens and 100, 91, 90, and 100%, respectively, for BAL specimens. Our results suggest that oral wash specimens are a potential noninvasive method to obtain a diagnostic specimen during P. carinii pneumonia infection and that it can be applied in a routine diagnostic laboratory....

    2009-01-01

    Full Text Available Cases of pulmonary aspergilloma without any predisposing factors are rarely reported. Clinical presentation varies from case to case. Here, we report a case of pulmonary aspergilloma in a 60-year-old male patient who was admitted to the Intensive Respiratory Care Unit with spontaneous pneumothorax. The patient had a history of dyspnea on exertion since 9 months and mild haemoptysis since the last 6 months. A computerised tomographic scan of the lungs showed a lesion in the left main bronchus along with obstructive emphysema of the right lung, moderate pneumothorax and mediastinal emphysema. Bronchoscopy was performed and the biopsy samples were processed for histopathological examination and culture on Sabouraud′s dextrose agar, which yielded growth of Aspergillus flavus. Repeat sputum samples also yielded the growth of A. flavus . The patient responded to intravenous liposomaamphotericin B and intercostal drainage.

    1980-11-01

    The article discusses the X-ray signs seen in 14 babies with unilateral emphysematous expansion. 7 of these infants had a lobar emphysema without any defect of the bronchial cartilage, whereas two had pulmonary cysts, one suffered from a congenital cystic adenomatoid pulmonary malformation, and one infant had been suffering from lymphangiectasy; in all cases, successful lobectomy had been performed. One patient with pneumatocele, one with a left-side agenesia of the upper lobe and one with a transient obstruction of the bronchi by a mucous plug, were given conservative treatment. The article discusses the X-ray differentiation of the following disturbances: pneumothorax, diaphragmatic hernia, compensatory and obstructive emphysematous expansion of a pulmonary lobe, cystic changes in the lung, and lobar emphysema, although this does not offer any possibility of discovering the reason for its occurrence. Attention is drawn to the diagnostic value of bronchoscopy and bronchography, as well as angiography, especially in case of suspected vascular malformation.

    2010-12-01

    Full Text Available Hepatitis-associated aplastic anemia occurs in up to 10% of all aplastic anemia cases. Syngeneic bone marrow transplantation is rare in patients with severe aplastic anemia and usually requires pre-transplant conditioning to provide engraftment. We report on a 29-year-old male patient with hepatitis-associated severe aplastic anemia who had a series of severe infectious conditions before transplantation, including tracheal inflammation. Life-threatening bleeding, which developed after bronchoscopy, was successfully treated with activated recombinant factor VII and platelet transfusions. Syngeneic peripheral blood stem cell transplantation using immunosuppressive treatment with antithymocyte globulin and cyclosporin A without high-dose pre-transplant conditioning was performed, followed by complete hematologic and hepatic recovery.

    José Cárdenas-García, MD

    2014-01-01

    Full Text Available A 44 year old male former smoker from Ecuador presented with productive cough for 3 weeks, positive tuberculin skin test, 40 lbs weight loss and right lower lobe collapse. He denied wheezing or hemoptysis. He was treated with antibiotics and ruled out for tuberculosis with negative sputum smear. Bronchoscopy showed an endobronchial lesion at the distal end of bronchus intermedius as cause of the collapse. Endobronchial biopsy of the lesion revealed an endobronchial leiomyoma, a rare cause of endobronchial tumor. The patient underwent bilobectomy as definite therapy for the leiomyoma due to its large size and possible extra-luminal extension, which made it not amenable to bronchoscopic resection or bronchoplasty. Differential diagnoses of endobronchial lesions are discussed along with clinical, radiographic, pathologic characteristics and various treatment modalities for endobronchial leiomyomas.

    The major types of cytologic preparations used in most laboratories to detect the lesions of the lower respiratory tract (LRT) are examined. These methods include sputum, bronchial washing, bronchial brushing, bronchoalveolar lavage (BAL) and fine-needle aspiration biopsy (FNAB). Sputum represents the simplest and most cost-effective sampling method even though fiberoptic bronchoscopy and radiologic guided FNAB are superseding it as the first diagnostic choice in most cases. There are advantages and disadvantages associated with each technique:bronchial brushing and FNABs tend to preserve both the cellular details and their architectural arrangement whereas sputum and bronchial washing often cause a variable degree of cellular degeneration and fragmentation. As a result, most pulmonary lesions may be detected and correctly diagnosed if multiple techniques are used to acquire diagnostic material. CT-guided FNAB represents the most effective method to achieve a correct diagnosis in pulmonary tumors. PMID:15852720

    Full Text Available A 28-year-old female with a history of chronic pancreatitis s/p total pancreatectomy and auto-islet cell transplantation developed a progressively enlarging right neck mass of 4 weeks duration. Coccidioides IgM antibodies were negative and IgG antibodies were positive by immunoassay (EIA, with titers 1:4 by complement fixation (CF. Fine needle aspiration with subsequent excisional biopsy of the right neck mass was performed and showed reactive lymphoid hyperplasia without fungal elements. Bronchoscopy with right upper lobe endobronchial biopsy and 4R lymph node endobronchial ultrasound-fine needle aspiration revealed granulomatous inflammation and Coccidioides spherules on Gomori's methenamine silver stain. Fungal cultures from the right neck mass fine needle aspiration, endobronchial biopsy, and 4R lymph node grew Coccidioides after three weeks of culture.

    2013-01-01

    Full Text Available Tracheomalacia is a rare condition characterized by weakness of tracheobronchial cartilaginous bridges. Severe weakness results in tracheal collapse during inspiration, obstructing normal airflow. Tracheomalacia may also be associated with esophageal atresia, tracheoesophageal fistula, and gastroesophageal reflux. Aortopexy is an established surgical procedure for treatment of severe tracheomalacia. A 2-month-old boy was scheduled for aortopexy. He had already undergone repair of tracheoesophageal fistula and had failed multiple attempts at extubation. Intraoperative flexible fiberoptic bronchoscopy was performed to guide the amount and direction of aortopexy for assuring the most effective tracheal decompression. Since tracheomalacia is best assessed in a spontaneously breathing patient, it was an anesthetic challenge to maintain an adequate depth of anesthesia while allowing the patient to breathe spontaneously. Throughout the intraoperative period, SpO 2 remained ≥96%. Following the procedure, the trachea was extubated and patient was able to breathe normally.

    We describe the treatment of a patient with long-gap esophageal atresia with an upper pouch fistula, mircogastria and minimal distal esophageal remnant. After 4.5 months of feeding via gastrostomy, a proximal fistula was identified by bronchoscopy and a thoracoscopic modified Foker procedure was performed reducing the gap from approximately 7-5 cm over 2 weeks of traction. A second stage to ligate the fistula and suture approximate the proximal and distal esophagus resulted in a gap of 1.5 cm. IRB and FDA approval was then obtained for endoscopic placement of 10-French catheter mounted magnets in the proximal and distal pouches promoting a magnetic compression anastomosis (magnamosis). Magnetic coupling occurred at 4 days and after magnet removal at 13 days an esophagram demonstrated a 10 French channel without leak. Serial endoscopic balloon dilation has allowed drainage of swallowed secretions as the baby learns bottling behavior at home. PMID:27012861

    Malignant mesothelioma is a tumour of serous surfaces mainly arising at the pleura or the peritoneum. The diagnosis encompasses multiple problems as there is no pathognomonic hallmark for the disease, there are multiple histological types and the differentiation from other tumours, such as adenocarcinoma or metastatic pleural disease, can represent quite a challenge. Usually a diagnosis of malignant mesothelioma carries a dismal prognosis with scarce therapeutical options.The present report concerns a patient with a diagnosis of malignant pleural mesothelioma with endobronchial extension. Biopsy specimens were obtained through fibreoptic bronchoscopy and blind needle pleural biopsy. The final diagnosis was only possible after careful histological evaluation with a combination of immunohistochemical markers. PMID:21686530

    2016-02-01

    Adult T-cell leukemia/lymphoma (ATLL) is usually preceded by infection with human T-cell lymphotropic virus I (HTLV-I). Patients with ATLL frequently get opportunistic infections of the lungs, intestines, and central nervous system. Pneumocystis pneumonia is commonly known as an AIDS defining illness. Grocott's methenamine silver stain of bronchoalveolar lavage (BAL) samples obtained via bronchoscopy remain the gold standard for diagnosis. Pulmonary cryptococcosis is seen in patients with T-cell deficiencies and a diagnosis is made by culture of sputum, BAL, or occasionally of pleural fluid. We present the second case of coinfection with these two organisms in a patient with ATLL who was successfully treated with trimethoprim-sulfamethoxazole, corticosteroids, and fluconazole. We illustrate the need for high clinical vigilance for seeking out an additional diagnosis, especially in immunocompromised patients if they are not improving despite receiving appropriate treatment.

  16. Proteomics as the Tool to Search for Lung Disease Markers in Bronchoalveolar Lavage

    Directory of Open Access Journals (Sweden)

    Isabelle Noël-Georis

    2001-01-01

    Full Text Available Most lung disorders are known to be associated to considerable modifications of surfactant composition. Numerous of these abnormalities have been exploited in the past to diagnose lung diseases, allowing proper treatment and follow-up. Diagnosis was then based on phospholipid content, surface tension and cytological features of the epithelial lining fluid (ELF, sampled by bronchoalveolar lavage (BAL during fiberoscopic bronchoscopy. Today, it appears that the protein content of ELF displays a remarkably high complexity, not only due to the wide variety of the proteins it contains but also because of the great diversity of their cellular origins. The significance of the use of proteome analysis of BAL fluid for the search for new lung disease marker proteins and for their simultaneous display and analysis in patients suffering from lung disorders has been examined.

  17. Radiation bronchitis in lung cancer patient treated with stereotactic radiation therapy

    International Nuclear Information System (INIS)

    We report a case of chronic radiation bronchitis that developed in a patient with lung cancer treated with fractionated stereotactic radiation therapy. A 73-year-old woman with a medically inoperable T1N0M0 adenocarcinoma of the lung was treated with stereotactic radiation therapy. By using eight non-coplanar ports, 50 Gy/5 fractions was delivered in two weeks. At four weeks, a partial response was obtained with no acute adverse reaction. She developed severe cough at six months. Fiberoptic bronchoscopy revealed thick circumferentially coated bronchial mucosa in close proximity to the tumor site. At 12 months, follow-up study confirmed marked stenotic change in the B6 segmental bronchus without tumor progression. (author)

    Results of 181 percutaneous needle aspiration biopsies performed with an 18-gauge needle during a period of 3 years were analyzed to determine efficacy and safety of the procedure. Biposies were performed in patients that could not be diagnosed by bronchoscopy or sputum cytology. The biopsy procedure with 18-gauge Crown needle was guided by fluoroscopy. The biopsy specimen placed in 10% formalin solution were histologically confirmed. In 160 patients (89%), the positive diagnosis was made by percutaneous needle aspiration biopsy. There were 153 lung lesions (120 malignant and 33 benign lesions) and 7 mediastinal lesions. The diagnostic accuracy of malignant and benign disease was 91% and 80% respectively. Complications included pneumothorax (n = 11) and hemothorax (n = 1): six of them required treatment with chest tube and the remainder showed spontaneous resorption. PCNB with an 18-gauge needle provided a reliable, relatively safe diagnostic tool to establish the diagnosis of both malignant and benign chest lesions.

PCNB with an 18-gauge needle provided a reliable, relatively safe diagnostic tool to establish the diagnosis of both malignant and benign chest lesions

    Full Text Available A 57 year-old bedbound paraplegic man developed a worsening productive cough after being hospitalized for several days. He was brought to the radiology suite for a CT scan of the chest, revealing a soft tissue density within his right main-stem bronchus, with volume loss of his right lung (Figure 1. Bronchoscopy was performed, yielding a 2 cm piece of broccoli, successfully removed with forceps (Figure 2. Culture from the bronchial aspirate was positive for Pseudomonas aeruginosa. The patient’s respiratory status dramatically improved after removal of the foreign body and commencement of pathogen-directed antibiotics. This study illustrates a dramatic example of healthcare-associated pneumonia (HCAP secondary to aspiration, as described by the American Thoracic Society / Infectious Diseases Society of America (1.

  1. Flow-volume loop abnormality detecting a previously unrecognized right upper lobe tracheal bronchus

    Full Text Available Tracheal bronchus is a rare anatomic variant in which a bronchus originates from the trachea. Patients may be asymptomatic or present with a variety of respiratory symptoms. We present a case of a patient who presented with a history of poorly controlled asthma and a persistent abnormality of the flow-volume loop. Bronchoscopy revealed a tracheal bronchus with narrowed right-sided bronchial orifices. An unrecognized tracheal bronchus may result in serious complications during elective or emergent endotracheal intubation. Spirometry testing may reveal abnormalities of the flow-volume loop associated with altered airflow. Relying on spirometric values without assessing the shape of the flow-volume loop may lead to misdiagnosis and inappropriate management of lung pathology.

    A 48-year-old male was admitted to our hospital because of abnormal pulmonary shadows and a decrease in visual acuity. He had a history of tuberculosis 20 years ago. The chest roentgenogram showed multiple pulmonary nodules throughout both lung fields. No definitive diagnosis was established either by brushing cytology or biopsy through bronchoscopy or percutaneous needle biopsy. Pathological examination of open lung biopsy specimen revealed that extensive, hyalinized lamellar collagen bundles arranged in whorls, parallel arrays. Plasma cells and lymphocytes were found between the collagen bands and germinal centers were seen at the periphery of the lesion. A definitive diagnosis of pulmonary hyalinizing granuloma was made on the basis of these histopathological findings. Although there is no established treatment for pulmonary hyalinizing granuloma, during 1 month of follow-up, posterior uveitis mildly resolved with glucocorticoid treatment and there had been a slight increase in visual acuity.

    A 40-year-old woman (a nonsmoker) with history of idiopathic thrombocytopenic purpura and a platelet count > 90,000 cells/μL without specific medication was referred to pulmonary clinic for evaluation of multiple pulmonary nodules. The patient presented to an outside hospital with fatigue, lack of energy, and dyspnea on exertion for 2 years. She denied fever, cough, chest pain, or weight loss. An initial chest radiograph showed bilateral multiple pulmonary nodules. A chest CT scan revealed multiple nodular lesions, varying in size, in all lobes of both lungs. There was no mediastinal lymphadenopathy or pleural effusion. There was no significant hypermetabolic activity on a subsequent fluorodeoxyglucose PET scan/CT scan, and there had been no significant change. She underwent CT scan-guided percutaneous transthoracic biopsy and bronchoscopy with transbronchial biopsies, all of which were inconclusive. An open lung biopsy was considered. PMID:25451362

    Full Text Available Pulmonary Langerhans cell histiocytosis is a rare interstitial lung disease characteristically affecting middle-aged smokers. It has unpredictable clinical course and may be associated with malignant neoplasms. Opportunistic lung infections are frequently considered when patients with Human immunodeficiency virus (HIV infection present with respiratory symptoms and an abnormal chest X-ray. Though fiberoptic bronchoscopy with bronchoalveolar lavage is diagnostic for infectious etiologies, surgical lung biopsies are preferred to diagnose noninfectious lung diseases and to help guide appropriate therapy. In the present study, we report a case of progressive bilateral lung infiltrates in a smoker with HIV infection which presented a diagnostic dilemma in view of coexistent HIV infection. Analysis of clinical symptomatology aided by surgical lung biopsy helped in diagnosis.

    The exogenous lipoid pneumonia, uncommon in adults, is the result of the inhalation and/or aspiration of lipid material into the tracheobronchial tree. This is often confused with bacterial pneumonia and pulmonary tuberculosis due to a nonspecific clinical and radiologic picture. It presents acutely or chronically and may result in pulmonary fibrosis. We describe here a case of lipoid pneumonia in a gas station attendant who siphoned gasoline to fill motorcycles; he was hospitalized due to presenting with a respiratory infection that was hard to resolve. The patient underwent bronchoscopy with bronchoalveolar lavage, which, on cytochemical (oil red O) evaluation, was slightly positive for lipid material in the foamy cytoplasm of alveolar macrophages. Due to his occupational history and radiographic abnormalities suggestive of lipoid pneumonia, a lung biopsy was performed to confirm the diagnosis. The patient was serially treated with segmental lung lavage and showed clinical, functional, and radiological improvement. PMID:25374742

    Lipoid pneumonia is an underdiagnosed disease that is caused by the aspiration of lipid particles into the lungs. Although most of the reported cases have been associated with the use of mineral oil as a laxative, other lipid substances can also cause the disease. We report the case of a 50-year-old female patient with a complaint of productive cough who was initially diagnosed with bronchial hyperresponsiveness and gastroesophageal reflux disease (GERD). The patient was treated for GERD. Because the productive cough persisted, the patient underwent chest CT, fiberoptic bronchoscopy, and open lung biopsy. She was diagnosed with lipoid pneumonia. The patient was questioned regarding the use of lipid substances, and she reported the chronic use of evening primrose oil. After the discontinuation of the substance and the maintenance of GERD treatment, her condition improved. PMID:21085832

    Five of nine active tandem mill operators exposed at work to aerosolized hydrocarbon mist were referred for evaluation of respiratory complaints. The worker with the longest exposure had reduced lung volumes; he was admitted to the hospital for detailed study. Exercise studies revealed work load limited by ventilation and arterial oxygen desaturation. Flexible fiberoptic bronchoscopy with bronchoalveolar lavage and transbronchial biopsy revealed evidence of lipoid pneumonia. Assessment of the mill revealed levels of respirable oil mist by personal samplers throughout the area far below the currently accepted standard of 5 mg/M3. These findings confirm a 20-year-old hypothesis of J.G. Jones regarding the hazard of oil mist in this industrial setting.

    Fire-eater's lung, an acute exogenous lipoid pneumonia, is caused when street performers accidentally inhale pyrofluids. We report the case of a young fire-eater who, 12 hours after inhaling an iso-alkanebased pyrofluid, developed fever, dyspnoea, dry cough and intense right chest pain. Radiographic signs of pneumonia emerged two days later. Computed tomography (CT) scans visualized an irregular area of parenchymal consolidation with an air bronchiologram and peripheral ground-glass opacities in the right middle lobe. The diagnostic work-up included microbiological and lung function tests, optic fibre bronchoscopy and an in-depth cyto-immunological analysis of bronchoalveolar lavage fluid. Symptoms gradually improved over a few days. A CT scan one month later showed the thickened parenchymal area in the right middle lobe had almost completely disappeared. PMID:21244782

    2014-12-01

    Full Text Available Tracheal diverticulum, defined as a benign outpouching of the tracheal wall, is rarely diagnosed in clinical practice. It can be congenital or acquired in origin, and most cases are asymptomatic, typically being diagnosed postmortem. We report a case of a 69-year-old woman who was hospitalized after presenting with fever, fatigue, pleuritic chest pain, and a right neck mass complicated by dysphagia. Her medical history was significant: pulmonary emphysema (alpha-1 antitrypsin deficiency; bronchiectasis; and thyroidectomy. On physical examination, she presented diminished breath sounds and muffled heart sounds, with a systolic murmur. Laboratory tests revealed elevated inflammatory markers, a CT scan showed an air-filled, multilocular mass in the right tracheal wall, and magnetic resonance imaging confirmed the CT findings. Fiberoptic bronchoscopy failed to reveal any abnormalities. Nevertheless, the patient was diagnosed with tracheal diverticulum. The treatment approach was conservative, consisting mainly of antibiotics. After showing clinical improvement, the patient was discharged.

    2014-01-01

    Full Text Available Inflammatory myofibroblastic tumour (IMT is a rare tumour affecting the tracheo-bronchial tree in the adult population. The clinical presentation of this tumour is diverse and diagnosis can be definitively clinched by histopathological examination. Treatment of this tumour usually requires surgical resection with bronchoscopic resection being described in few cases. We describe a 32 year old male presenting with hemoptysis who was diagnosed to have IMT. Resection of the tumour was done with the help of rigid bronchoscopy. Post-resection, hemoptysis stopped and no recurrence of tumour was noted on subsequent follow-up. We also present a systematic review of literature of all the cases of tracheo-bronchial IMT treated with bronchoscopic resection and conclude it to be a useful alternative to surgery in such cases.

    Eosinophilic angiocentric fibrosis (EAF) is a rare inflammatory disease that primarily involves the nose and sinuses. Involvement of the eye orbit and larynx has also been described. However, it is very rare for this disease to involve the lower respiratory tract and cause dyspnea. We describe a rare case of EAF involving the lower respiratory tract with airway narrowing. A 29-year-old female with a 7-year history of nasal obstruction presented with unexplained persistent dyspnea. EAF was diagnosed via endoscopic biopsy of an irregular mucosal lesion in the posterior wall of the right maxillary sinus. Chest computed tomography and bronchoscopy showed a diffuse inflammatory narrowing of the airway in the tracheobronchial trees. EAF can affect lower respiratory tracts with airway narrowing that can be characterized by dyspnea. We must consider narrowing of the lower respiratory tracts in patients with EAF complaining of unexplained persistent dyspnea.

    Coccidioidal infection is a well-recognised cause of pulmonary disease in certain parts of the south-western USA, Central and South America; however, it is rarely encountered elsewhere in the world. We describe the case of a previously healthy man presenting to a Dublin hospital with fever, dry cough and chest pain, following a visit to the western USA. Despite treatment with broad-spectrum antimicrobials, the patient developed progressive bilateral pulmonary infiltrates and a large pleural effusion. After extensive investigations including CT, bronchoscopy and pleural fluid analysis, a diagnosis of pulmonary coccidioidomycosis was made. Following the initiation of appropriate antifungal therapy, the patient made a full recovery. This case was of interest due to the rarity of the disease outside its areas of endemicity and the unusual findings associated with its diagnosis. PMID:27516109

    A five-year-old girl developed hoarseness with gradual worsening at the age of eight months. Three months later, she underwent bronchoscopy in which papillomas in the vocal cords, larynx and trachea were observed. Because of serious bronchospasm crises and respiratory failure, she needed several hospitalizations, definitive tracheostomy and multiple endoscopic procedures for papilloma excision. The most recent chest radiography (Figure A) and computed tomography (CT) scans (Figures B and C) showed a nodule inside the trachea and multiple pulmonary nodules, cysts and consolidations. The anatomopathological findings from curettage of the lesions revealed benign squamous-cell papillomas. Recurrent respiratory papillomatosis (RRP) is directly related to the human papillomavirus (HPV). Its spread to the lower airways is uncommon, with involvement of trachea and/or proximal bronchi in 5% of the patients, and extension to the lungs in only 1% of the cases. (author)

    Evaluation of the airway for the presence of granulation tissue prior to removal of a tracheostomy is essential to prevent sudden respiratory decompensation secondary to obstruction. Airway examination in a brain and/or spinal cord injured patient is especially difficult under fluoroscopy. The patient's lack of mobility results in poor visualization of the trachea, secondary to the overlying dense osseous components of the shoulders and thoracic cage. A CT localization view (digital view), which allows manipulation and magnification of the digital data in order to see the hidden airway and detect associated obstructing lesions, is proffered as an alternative technique to high KV, magnification technique. Thirteen examinations were performed satisfactorily in eleven patients examined by this technique with little expenditure of time, physical exertion, and irradiation. The sensitivity, specificity and accuracy of digital airway examination were 100%, 67% and 92% respectively with bronchoscopy used as the standard.

    Patients with 4MRGN Acinetobacter baumanii infections in a burn unit represent great challenge. The structured management with 7 involved patients in such a situation is presented. After discovering the infectious trigger a management team is established. An immediate stop for further admissions was announced and all infected room areas and medical equipment were analysed for infection foci. The infected patients were transferred to regional hospitals or a rehabiltation hospital after finishing all surgical procedures. In one case, for whom further operations were needed, a transfer to a separated area of the intermediate care unit (IMC) within the hospital was arranged. The performed analysis of infection foci indicated a bronchoscopy tower to be the infection source. The outbreak was terminated after transferring all patients, final disinfection and subsequent nebulisation with 5-6% hydrogen peroxide within 18 days. PMID:25162239

    Full Text Available Epithelial-myoepithelial carcinomas are rare tumors that primarily originate in the salivary glands but have also been found in the tracheobronchial tree. We report the first case of epithelial-myoepithelial carcinoma associated with sarcoidosis. A 61 year old Hispanic man presented with altered mental status and hypercalcemia. Imaging revealed diffuse intra-thoracic and intra-abdominal lymphadenopathy. A diagnostic bronchoscopy was performed where an incidental tracheal nodule was discovered and biopsied. Pathology was consistent with epithelial-myoepithelial carcinoma. Lymph node biopsy demonstrated non-caseating granulomas consistent with sarcoidosis. Patient underwent tracheal resection of the primary tumor with primary tracheal reconstruction. Hypercalcemia subsequently normalized with clinical improvement. Repeat CT imaging demonstrated complete resolution of lymphadenopathy. Our findings are suggestive of a possible paraneoplastic sarcoid-like reaction to the epithelial-myoepithelial carcinoma with associated lymphadenopathy and symptomatic hypercalcemia.

    The nasogastric tube (NGT) has become a frequently used device to alleviate gastrointestinal symptoms. Nasogastric tube syndrome (NTS) is an uncommon but potentially life-threatening complication of an indwelling NGT. NTS is characterized by acute upper airway obstruction due to bilateral vocal cord paralysis. We report a case of a 76-year-old man with NTS, induced by an indwelling long intestinal tube. He was admitted to our hospital for treatment of sigmoid colon cancer. He underwent sigmoidectomy to release a bowel obstruction, and had a long intestinal tube inserted to decompress the intestinal tract. He presented acute dyspnea following prolonged intestinal intubation, and bronchoscopy showed bilateral vocal cord paralysis. The NGT was removed immediately, and tracheotomy was performed. The patient was finally discharged in a fully recovered state. NTS be considered in patients complaining of acute upper airway obstruction, not only with a NGT inserted but also with a long intestinal tube.

    2009-06-01

    Full Text Available Abstract Introduction Two cases of iatrogenic tension pneumothorax in children are reported. Case presentations Case 1: A 2-year-old boy with suspected brain death after suffering multiple trauma suddenly developed intense cyanosis, extreme bradycardia and generalized subcutaneous emphysema during apnea testing. He received advanced cardiopulmonary resuscitation and urgent bilateral needle thoracostomy. Case 2: A diagnostic-therapeutic flexible bronchoscopy was conducted on a 17-month-old girl, under sedation-analgesia with midazolam and ketamine. She very suddenly developed bradycardia, generalized cyanosis and cervical, thoracic and abdominal subcutaneous emphysema. Urgent needle decompression of both hemithoraces was performed. Conclusion In techniques where gas is introduced into a child's airway, it is vital to ensure its way out to avoid iatrogenic tension pneumothorax. Moreover, the equipment to perform an urgent needle thoracostomy should be readily available.

    2010-01-01

    Full Text Available Exercise-induced pulmonary hemorrhage (EIPH commonly occurs in race horses. Thromboelastometry (TEM investigates the whole hemostatic process by evaluating the viscoelastic properties of the blood clot from its formation to fibrinolysis. The aim of this study was to assess whether horses with EIPH have abnormal thromboelastometric profiles. Intrinsic and extrinsic pathways, fibrinogen activity and fibrinolysis were investigated by TEM before and after the race in negative controls and in horses on which EIPH was confirmed by bronchoscopy. Compared with controls, horses with EIPH had an increased coagulability in both pre- and postrace samplings, especially for the intrinsic pathway and for the fibinrolytic activity. These results suggest that coagulation is preactivated in horses prone to develop EIPH, possibly due to recent or recurrent hemorrhage.

    Hemoptysis is the expectoration of blood that originates from the lower respiratory tract. It is usually a self-limiting event but in fewer than 5% of cases it may be massive, representing a life-threatening condition that warrants urgent investigations and treatment. This article aims to provide a comprehensive literature review on hemoptysis, analyzing its causes and pathophysiologic mechanisms, and providing details about anatomy and imaging of systemic bronchial and nonbronchial arteries responsible for hemoptysis. Strengths and limits of chest radiography, bronchoscopy, multidetector computed tomography (MDCT), MDCT angiography and digital subtraction angiography to assess the cause and lead the treatment of hemoptysis were reported, with particular emphasis on MDCT angiography. Treatment options for recurrent or massive hemoptysis were summarized, highlighting the predominant role of bronchial artery embolization. Finally, a guide was proposed for managing massive and non-massive hemoptysis, according to the most recent medical literature. PMID:24808437

    2013-01-01

    Full Text Available The present report describes a 60-year-old Caucasian woman who presented with progressive dyspnea, cough and wheeze. A computed tomography scan of the chest showed innumerable bilateral inflammatory pulmonary nodules with bronchovascular distribution and a mediastinal and hilar infiltrative process with calcified lymphadenopathy leading to narrowing of lobar bronchi and pulmonary arteries. An echocardiogram revealed pulmonary hypertension. Bronchoscopy showed left vocal cord paralysis and significant narrowing of the bilateral bronchi with mucosal thickening and multiple nodules. Transbronchial biopsy was compatible with sarcoidosis. Despite balloon angioplasty of the left lower lobe and pulmonary artery, and medical therapy with oral corticosteroids, her symptoms did not significantly improve. To the authors’ knowledge, the present report describes the first case of pulmonary sarcoidosis resulting in major airway, vascular and nerve compromise due to compressive lymphadenopathy and suspected concurrent granulomatous infiltration. Its presentation mimicked idiopathic mediastinal fibrosis.

    Full Text Available It is important to extract foreign bodies for avoiding life-threatening complications. They can lead to death if they are not treated. Different signs and symptoms could occur according to the complete or partial airway obstruction. Foreign body aspiration is a rare incident in adults. The organic foreign materials such as foods are found to be aspirated more commonly and are usually settled in the right bronchial system. However, dental prosthesis and teeth aspirations are rare in literature. In our study, a 52-year-old male patient who had aspirated the front part of his lower dental prosthesis accidentally is presented and the foreign body is extracted by using rigid bronchoscopy. There are many causes of aspiration but dental prosthetic aspirations should be kept in mind during sleep. For this reason, dental apparatus must be taken out while asleep.

    Keiko Mitaka Komatsuzaki

    2014-01-01

    Full Text Available A 33-year-old woman was admitted for a pseudocroup-like cough and wheezing after general anesthesia. Several months ago, she had undergone cardiac re-operation and turbinectomy, both of which had involved difficult intubations. Bronchoscopy indicated a pin-hall-like subglottic stenosis; therefore, emergency tracheotomy was performed. Six years later, a computed tomography scan demonstrated progressive stenosis of the entire circumference of the trachea and main bronchi. She died at 40 years. Her autopsy revealed marked tracheobronchial stenosis. She had many medical histories that had gone undiagnosed and had been clinically ill with only heart defects. She did not have coloboma but had microphthalmos, atresia choanae, retarded growth development, and deafness; thus, we diagnosed CHARGE syndrome that refers to multiple congenital anomalies, including airway abnormalities, which can lead to secondary complications such as traumatic stenosis after intubation. Physicians should have knowledge of this rare disease and should pay special attention to potential airway problems.

  7. Anesthetic Management of Direct Laryngoscopy and Dilatation of Subglottic Stenosis in a Patient with Severe Myasthenia Gravis

    Hesham A. Elsharkawy

    2012-01-01

    Full Text Available We describe the anesthetic management of a patient with severe myasthenia gravis and tracheal stenosis; the patient was scheduled for direct laryngoscopy and dilatation. The combination of myasthenia gravis and tracheal obstruction presents several difficulties for anesthetic management. The airway is shared; therefore, any complications are also shared by the anesthesiologist and bronchoscopists. The potential for respiratory compromise in patients undergoing the two procedures requires that anesthesiologists be familiar with the underlying disease state, as well as the interaction of anesthetic and nonanesthetic drugs in a case involving myasthenia gravis. We reviewed the literature and report our experience in this case. There is no strong evidence for choosing one approach to general anesthesia over another for bronchoscopy. Careful preoperative planning and experience in airway management and jet ventilation are crucial to prevent an adverse outcome and obtain favorable results.

    managing those changes. OBJECTIVES: To describe the endoscopic abnormalities found in the airway mucosa of a group of patients with WG undergoing bronchoscopy at Hospital das Clínicas of the Faculdade de Medicina, Universidade de São Paulo (HC-FMUSP, and to report the therapeutic bronchoscopic interventions used in some cases. METHODS: The study assessed 15 patients diagnosed with GW from the Vasculitis Outpatient Clinic of the Department of Pulmonology, HC-FMUSP, referred for bronchoscopy at the Service of Respiratory Endoscopy, HC-FMUSP, from 2003 to 2007. RESULTS: Fifteen patients were studied [11 females (73.33%]; mean age, 34 ± 11.5 years. Airway changes were found in 80% of the patients, and the most frequent endoscopic finding was subglottic stenosis (n = 6. Therapeutic bronchoscopy was performed in three patients with subglottic stenosis and in other three patients with bronchial stenosis, all showing good results. CONCLUSION: Bronchoscopy allows for diagnosing, monitoring, and treating the airway lesions in WG, being a minimally invasive therapeutic option in selected cases.

  9. External radiation therapy for roentgenographically occult lung cancers

    International Nuclear Information System (INIS)

    From January 1982 to May 1991, the authors have treated 13 cases of a roentgenographically occult lung cancer by using a 4∼10 MV photon beam. All 13 patients were males whose ages ranged from 53 to 84 years (mean: 71.4 years) and each was a heavy cigarrette smoker. In each instance, a sputum cytologic study uncovered abnormal findings and bronchoscopy revealed a localized cancer. For radiotherapy, radiation doses ranged from 50∼70 Gy (mean: 64.0 Gy), and the radiation field ranged from 25.75 to 90 cm2 (mean: 43.2 cm2). During the follow-up period of 11 to 68 months (mean: 34.2 months), 2 patients died of the carcinoma, 1 still has the carcinoma, and 3 died of other causes. The 5-year survival rate was 62%.

    Penicillium notatum is a fungus that widely exists in the environment and is often non-pathogenic to humans. However, in immunocompromised hosts it may be recognized as a cause of systemic mycosis. A 44-year-old man with acute myeloid leukemia (AML) was admitted to our hospital with fever and neutropenia. Due to no improvement after initial treatment, he underwent bronchoscopy. The patient was found to have P. notatum and Pneumocystis jiroveci infection, and therefore was given voriconazole, primaquine and clindamycin. The patient was successfully treated and suffered no complications. Conclusion: This case highlights P. notatum as a cause of infection in immunocompromised patients. To the best of our knowledge, mixed lung infection with P. notatum and P. jiroveci in a patient with AML has not been previously reported.

    A young house wife presented with low grade fever, cough, haemoptysis and SOB of unknown aetiology for 40 days duration. Respiratory system examination revealed diffuse crepts and rhonchi. Other organ system examination did not reveal any abnormality. X-ray chest PA view and CT thorax showed diffuse bilateral necrotising nodular lesions of various sizes with small pleural effusion. She also had low resting oxygen saturation with falling haematocrit. Her Serum was week positive for p-ANCA and negative for MPO-ANCA. Bronchoscopy revealed continuous bloody aspirates. We could not isolate any organisms in any of the specimens from her and she was unresponsive to any of the antibiotics either. Based on the clinical, laboratory data, radiological features and positive outcome to pulse therapy of methylprednisolone and cyclophosphamide, she was diagnosed as a case of IPIPC. PMID:25624599

  12. Churg–Strauss Syndrome Presenting with Endobronchial Masses

    2015-12-01

    Full Text Available Churg–Strauss syndrome is a condition with unknown etiology and asthma, allergic rhinitis, eosinophilic infiltration of blood and tissues, and transient infiltration of the lungs. It occurs mostly in the 3rd–4th decades of life with an incidence of 2.4/1000000. Presentation frequently involves nodular lung infiltrations, infiltrations with cavity, ground-glass appearance, and alveolar opacity. However, endobronchial mass is an unexpected presentation. In the current case report, we present a 45-year-old male patient who was receiving asthma therapy for 5 years. In the last follow-up visit, we identified a mass in the right hilum on X-ray radiography and performed fiberoptic bronchoscopy. Pathologic examination of biopsy material verified the diagnosis of Churg–Strauss syndrome. Bronchial mass is an unexpected presentation of Churg–Strauss syndrome and pathologic examination is essential to distinguish it from pulmonary malignancies

    2015-12-01

    Transbronchial lung biopsy (TBLB) is uncommonly performed in non-malignant conditions because of its low sensitivity and small tissue samples. It is not routinely performed in Australia to investigate idiopathic pulmonary fibrosis, although it can be a useful adjunct in obtaining tissue diagnosis in selected conditions in interstitial lung disease (ILD). A 52-year-old non-smoker received a living unrelated renal transplant in January 2014 but developed insidious onset of dyspnea on exertion 1 year later. Computed tomography of the thorax showed bilateral persistent ground glass opacifications with a characteristic crazy paving pattern, although P neumocystis jirovecii pneumonia was more concerning. He was treated as P neumocystis jirovecii pneumonia but his initial bronchoscopy failed to confirm either diagnoses. He then went on to TBLB that showed the presence of periodic acid-Schiff staining material. We conclude that TBLB is a useful adjunct to obtain histological diagnosis of ILD in carefully selected patients with appropriate radiological indications. PMID:26740882

    Alveolar proteinosis is a rare chronic lung disease, especially in children, characterized by abnormal accumulation of lipoproteins and derived surfactant in the intra-alveolar space that generates a severe reduction of gas exchange. Idiopathic presentation form constitutes over 90% of cases, a phenomenon associated with production of autoimmune antibodies directed at the receptor for granulocyte-macrophage colony-stimulating factor. A case of a girl of 5 years of age treated because of atypical pneumonia with unfavorable evolution due to persistent hypoxemia is presented. The diagnosis is obtained through pathologic examination of lung biopsy by thoracotomy, as treatment is carried out by 17bronchopulmonary bronchoscopy lavages and the patient evidences marked clinical improvement.

    Extrinsic airway compression due to chest wall deformity is not commonly observed. Although this condition can be diagnosed more easily with the help of multidetector CT, the standard treatment method has not yet been definitely established. We report a case of an eighteen-year-old male who suffered from severe extrinsic tracheal compression due to scoliosis and straightening of the thoracic spine, confirmed on CT and bronchoscopy. The patient underwent successful placement of tracheal stent but later died of bleeding from the tracheostomy site probably due to tracheo-brachiocephalic artery fistula. We describe the CT and bronchoscopic findings of extrinsic airway compression due to chest wall deformity as well as the optimal treatment method, and discuss the possible explanation for bleeding in the patient along with review of the literature.

    Radiation therapy is an integral part of treatment for head and neck cancer, but its use is not without complications. We describe the first reported sternoclavicular-tracheal fistula resulting from osteoradionecrosis (ORN) at the medial clavicle. This ORN resulted from definitive radiation therapy for a primary pyriform sinus squamous cell carcinoma. The diagnosis of ORN was made by fiberoptic bronchoscopy. The physiologic damage of ORN is based on a compromised blood supply and altered metabolism of bone formation secondary to effects of ionizing radiation. Treatment requires meticulous hygiene, antibiotics, and debridement as conservative therapy. Radical surgery and reconstruction may be indicated in refractory cases. A thorough preirradiation assessment of patients is mandatory to decrease the incidence of radiation-induced ORN.

    A broad spectrum of congenital upper airway anomalies can occur as a result of errors during embryologic development. In this review, we will describe the clinical presentation, diagnosis, and management strategies for a few select, rare congenital malformations of this system. The diagnostic tools used in workup of these disorders range from prenatal tests to radiological imaging, swallowing evaluations, indirect or direct laryngoscopy, and rigid bronchoscopy. While these congenital defects can occur in isolation, they are often associated with disorders of other organ systems or may present as part of a syndrome. Therefore workup and treatment planning for patients with these disorders often involves a team of multiple specialists, including paediatricians, otolaryngologists, pulmonologists, speech pathologists, gastroenterologists, and geneticists.

    Tracheobronchial fibromas are very rare, locally-invasive tumors of the airways. Fewer than 30 cases have been reported within the English-speaking literature. Historically, these neoplasms have been diagnosed as isolated endobronchial masses, with affected patients presenting with wheezing, cough, stridor, hemoptysis, dyspnea, or pneumonia. We report the case of 39-year-old man with multiple, synchronous endobronchial fibromas causing unilobar emphysema. A computed tomographic scan and bronchoscopy with biopsy were performed preoperatively to diagnose these lesions in the orifices of the anterior segment and the lingula within the left upper lobe. The patient underwent successful video-assisted left upper lobectomy, without recurrence at 3 years. This is the first report of a synchronous presentation of multiple pulmonary endobronchial fibromas within the same patient and the first report of endobronchial fibroma presenting as unilobar air trapping. Recognition of the unusual presentation of this uncommon pathology can lead to timely intervention. PMID:26354646

    2015-05-01

    We are reporting 3 cases of pediatric endobronchial tumors presented with recurrent pneumonia. The median age of patients, at time of presentation, was 10.6 years. All patients presented with recurrent pneumonia with a mean time to occurrence, after onset of symptoms, of 14 mo. Bronchoscopy was early performed as part of diagnostic work-up and it revealed an endobronchial mass in every case. Complete surgical resection was performed in all cases, with lung preservation in two of them. Neither post-operative chemotherapy nor radiotherapy was required. The mean duration of follow-up was 7 years and all patients are still alive and disease-free. Recurrent pneumonia, in pediatrics, should raise the suspicion of an obstructing lesion, congenital malformation or systemic disease. A systematic approach is useful for organize the clinicians initial workup. Prompt diagnosis allows parenchymal-sparing surgery, which offers the best chance of cure and reduces clinical and functional complications in these patients. PMID:26015878

  2. Combination of fluorescence imaging and local spectrophotometry in fluorescence diagnostics of early cancer of larynx and bronchi

    International Nuclear Information System (INIS)

    The results of comparative studies of autofluorescence and 5-ALA-induced fluorescence of protoporphyrin IX, used in the diagnostics of early cancer of larynx and bronchi, are presented. The autofluorescence and 5-ALA-induced fluorescence images of larynx and bronchial tissues are analysed during the endoscopic study. The method of local spectrophotometry is used to verify findings obtained from fluorescence images. It is shown that such a combined approach can be efficiently used to improve the diagnostics of precancer and early cancer, to detect a primary multiple tumours, as well as for the diagnostics of a residual tumour or an early recurrence after the endoscopic, surgery or X-ray treatment. The developed approach allows one to minimise the number of false-positive results and to reduce the number of biopsies, which are commonly used in the white-light bronchoscopy search for occult cancerous loci.

    Full Text Available A 36-year-old man with AIDS and disseminated coccidioidomycosis presented with severe right chest pain, shortness of breath, and a right-sided pneumothorax on CXR. A pigtail catheter was placed with near resolution of the pneumothorax. A bronchoscopy with bronchoalveolar lavage revealed spherules on cytology as well as coccidioidomycosis on culture. No other pathogens were identified. The pigtail catheter was removed three days later with resolution of the pneumothorax. Rupture of subpleural coccidioidomycosis cavity into the pleural space resulting in pyopneumothorax and/or bronchopleural fistula is rare with reported rates of 1.4 – 2.6% for cavitary lesions (1. Despite antiretroviral therapy and an undetectable viral load, disease was unresponsive to fluconazole. Therapy was subsequently initiated with amphotericin B lipid complex, which resulted in significant improvement of his disease.

    Hodgkin lymphoma (HL) typically presents in the nodal regions at an early stage of the disease. Occasionally, patients can present with disease in extranodal regions. We report a case of HL in a 25-year-old female who presented to the emergency department following a motor vehicle accident with incidental findings of pulmonary cavitary lesions, fever, tachycardia, anemia, leukocytosis and thrombocytosis. This case illustrates the difficulty in diagnosis when the disease presents in extranodal regions with nonspecific systemic symptoms. Complete workup for infectious and autoimmune etiology was performed and found to be negative. CT guided biopsy and bronchoscopy failed to yield the diagnosis; a video-assisted thoracoscopic surgery was necessary to obtain the diagnosis of advanced-stage HL in this patient. PMID:26793930

    Visceral leishmaniasis is characterized by fever, cachexia, hepatosplenomegaly, pancytopenia, and hypergammaglobulinemia. Cough may be a presenting symptom as well. However, pulmonary involvement is considered rare and mainly described in immunocompromised patients. We describe a case of an immunocompetent adult whose clinical presentation was dominated by cough and hemoptysis. Bronchoscopy revealed a discreet polypoid mucosal endobronchial lesion whose biopsy yielded Leishmania amastigotes within histiocytes. Transbronchial needle biopsy of a right paratracheal lymph node was also positive. Leishmania amastigotes were also found on bone marrow and liver biopsies. Treatment with IV Amphotericin B was successful. In conclusion, cough should not be overlooked as a presenting symptom of visceral leishmaniasis and may be a sign of pulmonary involvement.

    2006-01-01

    Abstract:Thoracic endometriosis is a rare disorder. It can be divided into pleural and pulmonary parenchymal endometriosis according to the site of the lesion. In this article 3 typical cases of thoracic endometriosis (case 1 is pleural endometriosis, case 2 and 3 are pulmonary parenchymal endometriosis) were described, and the various presentations, pathogenesis, diagnosis, and therapies of thoracic endometriosis were reviewed. The pathogenesis of thoracic endometriosis has not been established clearly yet. Recurrent right-sided pneumothorax or hemoptysis that occurs within days of the onset of menstruation is the most common manifestation. The correlation between the patient's symptoms and menses is essential to establish the diagnosis. Radiographic studies, bronchoscopy, and thoracoscopy may support the diagnosis. Pathologic evidence is not present universally. Therapeutic interventions include medical and surgical options, which should be individualized for each patient.

    2010-01-01

    Full Text Available Transbronchial needle aspiration (TBNA has the potential to allow adequate mediastinal staging of non-small cell lung cancer with enlarged lymph nodes in most patients without the need for mediastinoscopy. Metastasis to the mediastinal lymph nodes is one of the most important factors in determining resectability and prognosis in non-small cell lung cancer. The importance of TBNA as a tool for diagnosing intrathoracic lymphadenopathy as well as in the staging of lung cancer has been reported in various studies. We performed a literature search in PubMed and Journal of Bronchology using the keyword transbronchial needle aspiration. TBNA is a safe and effective procedure to diagnose mediastinal lymphadenopathy. Real-time bronchoscopic ultrasound-guided TBNA is the new kid on the block, which can further enhance the sensitivity of bronchoscopy in the diagnosis of mediastinal lesions.

    Tracheobronchial airway foreign body aspiration (FBA) in children is a common and serious pediatric medical emergency. With the increasing use of small magnets in home offices, in toys and the kitchen, inhalation of small magnets has become an increasing risk to children. We present a case of a 9-year-old boy who presented with cough and dyspnea three days following inhalation of an 3 cm-sized oval magnet. The history and the chest radiograph were important in planning for the removal of the aspirated foreign body. In this case, we removed the inhaled magnet using rigid bronchoscopy under general anesthetic. We herein reviewed the recent reports on the incidence and management of small foreign body aspiration as a pediatric emergency. PMID:26770610

    Full Text Available Endobronchial tuberculosis (EBTB is a sequelae of pulmonary tuberculosis (TB that extends to the endobronchial or endotracheal wall causing inflammation, edema, ulceration, granulation or fibrosis of mucosa and submucosa. This case depicts a 20 year old foreign-born woman with a history of active pulmonary TB on anti-TB chemotherapy, who presented with worsening stridor, dyspnea, cough and weight loss. The disease state was diagnosed with multiple modalities including, spirometry, CT scan of the neck, and bronchoscopy. The biopsies of the tracheal web revealed fibrotic tissue without any granulomas or malignancy establishing the diagnosis of EBTB. Serial balloon dilations and anti-neoplastic therapy with Mitomycin C was used to accomplish sufficient airway patency to relieve her symptoms. ETBT is a rare consequence of TB, which although has a low incidence in the United States, so physicians should have a high clinical suspicion based on the need for prompt intervention.

    The prognosis of bronchogenic carcinoma depends on its histology and the time of its first diagnosis. The 5-year-survival rate after radiation treatment is 3-10%. It is much better for tumors detected and operated in an early stage, averaging 21%. The roentgenomorphology of central and peripheral bronchogenic carcinoma and the differential diagnosis is demonstrated on a selected group of 300 patients seen in the "Klinik und Poliklinik für Radiologie" in Munich between 1975 and 1979. In conclusion we think it not justified to hesitate performing bronchoscopy and/or percutaneous needle aspiration lung biopsy in cases of unclear peripheral or central pulmonary shadows, considering the low risks of the two procedures.

    We describe a case of a very difficult intubation which was safely navigated through careful planning. Our patient presented initially with increasing hoarseness and shortness of breath over a 6-month period. This was investigated and the patient was found to have a large vocal cord mass and was referred for urgent microlaryngoscopy and vocal cord polypectomy. On the day of surgery the obstruction was noted and awake fiberoptic bronchoscopy was used with a remifentanil infusion. Given the mass was large and increased in size with expiration, the time frame to pass the tube was extremely short. We delivered a transtracheal injection of local anaesthesia. This approach allowed for safe passage of the endotracheal tube. In patients such as this it may be worth considering the use of a transtracheal injection in the first instance. PMID:26628451

  1. Aerosolized pentamidine: Effect on diagnosis and presentation of Pneumocystis carinii pneumonia

    International Nuclear Information System (INIS)

    The objective of this study was to determine the effect of previous aerosolized pentamidine therapy on diagnosis and presentation of Pneumocystis carinii pneumonia. This was a retrospective study of fifty-two consecutive patients with P. carinii pneumonia and underlying infection with the human immunodeficiency virus (HIV) who had bronchoscopy. Twenty-one patients who were on aerosolized pentamidine therapy served as the study group. Thirty-one patients who had not received the drug served as the control group. The yield of bronchoalveolar lavage for P. carinii pneumonia was 62% for the study group and 100% for the control group (P less than 0.05). This lower yield was significant for the subset of patients having their first episode of P. carinii pneumonia. The yield of transbronchial biopsy was similar for both groups of patients (81% compared with 84%). The yield of bronchoscopy was not influenced by use of zidovudine. Review of lavage specimen slides suggested that there may be fewer organisms present in patients receiving aerosolized pentamidine. An atypical roentgenographic presentation of upper lobe predominant infiltrates was seen in 38% of the study patients and 7% of the control patients. In addition, pneumothoraces and cystic changes were also frequently seen in the study patients. Gallium scans, when done, were also atypical in the study group. Markers of the severity of disease, however, were similar in both groups. The yield of bronchoalveolar lavage for P. carinii pneumonia in HIV-infected patients is lower in patients receiving aerosolized pentamidine. Unusual roentgenographic presentations and atypical gallium scans are also found in this setting

    Full Text Available Diffuse parenchyma lung disease (DPLD encompasses a hetero - geneous group of disorders, characterized by a spectrum of inflammatory and fibrotic changes affecting alveolar walls and air spaces. They comprise over 200 entities and include a wide spectrum of diseases, many uncommon and many of unknown etiology. The incidence and prevalence rates of DPLD have not been precisely estimated due to difficulties in ascertaining a specific diagnosis on a specific disease. MATERIAL & METHODS : Prospective observational study done on 20 adult patients with radiologically diffuse parenchymal lung disease admitted between January 2010 and May 2015 in Govt. General & Chest Hospital, Hyderabad were subjected for Transbronchial Lung Biopsy via flexible fibreoptic bronchoscopy, without fluoroscopic guidance. RESULTS : Out of 20 patients studied adequate lung tissue was obtained in 15 patients, yield of the procedure was 75%. Out of 15 patient’s histopathological diagnosis of chronic interstitial pneumonia is seen in 5 members, interstitial fibrosis is seen in 4 members, non caseating granulomas seen in 4 members, pulmonary alveolar protenosis was seen in 1 member and normal lung histopathology was seen in 1 members. Diagnostic yield of the procedure was 93.3% and overall diagnostic yield was 70%. Two patients developed post procedure pneumothorax. Both of them underwent closed - tube thoracostomy, lung expanded well and ICD was removed in 4 days. No significant bleeding was observed in any patient. No mortality was observed after the procedure . CONCLUSIONS : Transbronchial lung biopsy through flexible bronchoscopy is a simple, safe and effective procedure for the diagnosis of diffuse parenchymal lung diseases. Complications were observed in only few patients out of twenty, which were successfully managed with ICD.

    Full Text Available Background and objective It is a complex problem and difficult treatment for tracheobronchial stenoses/occlusions involving in carina. The aim of this study is to investigate the feasibility and efficiency of argon plasma coagulation (APC and bifurcated covered Z-type stents (CZTS placement for the treatment of tracheobronchus stenoses and esophagorespiratory fistula (ERF. Methods Thirty-two cases with airway disorders were retrospectively reviewed for the treatment of APC and CZTS placement. Under the bronchoscopic guidance, APC was first given in patients with airway stenoses, then CZTS was placed under the fluoroscopic and flexible bronchoscopic guidance either with airway stenoses or ERF. Results APC was first given in 19 patients with airway stenoses. Airway structures were significantly improved after APC procedure (57.4%-72.1% before APC vs 12.8%-25.8% after APC. Thirty-two CZTS were technically successfully placed in 30 out of 32 cases involving in carinal bifurcation. After APC and stent placement, short breath index was significantly reduced and karnofsky physical score (KPS increased obviously. The endobronchial defects were successfully palliated with bifurcated CZTS placed under fluoroscopy and flexible bronchoscopy in 12 out of 13 patients with ERFs. There is no bleeding introprocedure. Mucous retention was very common in all types of the stents less than 2 weeks after stenting, which required debridement by bronchoscopy and could be prevented by normal saline solution nebulizations. Granuloma developed at the ends of stents after 1 month of stenting which all of them were treated successfully with APC and CO2 cryosurgery. Conclusion Utilization of APC and retrieval bifurcated CZTS placement is a simple and safe protocol for the management of airway complex stenoses involving the tracheal carina and ERF.

We retrospectively reviewed medical records of 2,000 TFB patients (1,260 males and 740 females who were treated between January 2010 and December 2013. Chest radiography and computed tomography were performed to diagnose TFBs. The location and type of foreign bodies (FBs, anesthesia methods, and treatment outcomes and complications were analyzed. Overall, 72.5% of our patients with TFB were aged between 1 years and 3 years. Plant-based FBs are the most common FB type, accounting for 91.5%. Almost 52.1% of the FBs were encountered in the right bronchus. The coincidence rate for computed tomography-based three-dimensional reconstruction was significantly greater than that for chest X-ray examination (98.7% vs 82.0%, P<0.01. Under general anesthesia, the FBs were removed by rigid bronchoscopy. Neither anesthesia complication nor intraoperative hypoxemia occurred. There were seven deaths from acute obstructive asphyxia and eight from residual FB-induced chronic asphyxia and respiration-circulation failure. In conclusion, early diagnosis and prompt treatment of TFBs with rigid bronchoscopy under general anesthesia is effective in reducing complications and mortality in affected children.

  5. Bronchial artery embolization in the treatment of massive hemoptysis

    International Nuclear Information System (INIS)

    Objective was to evaluate the efficacy of bronchial arteriography and bronchial artery embolization (BAE) in the management of massive hemoptysis in a developing Asian country. A retrospective review was carried out from March 2000 to March 2005 to evaluate the demographics, clinical presentation, radiographic studies, bronchoscopy results, and complications of bronchial arteriography and BAE at a tertiary care hospital in Pakistan. Fourteen patients (9males, 5 females) with a mean age of 49 years underwent bronchial arteriography and BAE for massive hemoptysis. Hemoptysis was caused by bronchiectasis (10 patients), active pulmonary tuberculosis (3 patients), and lung malignancy (one patient). A CT scan of the chest was carried out in 11 patients, which revealed bronchiectasis (8 patients), cavity with infiltrates (3 patients), and mass lesion (one patient). Bronchoscopy was performed in all patients. Bleeding lobe or segment was identified in 12 patients. Bronchial arteriography revealed hypervascularity (13 patients), bronchial artery hypertrophy (5 patients), hypervascularity with shunting (one patient), dense soft tissue staining (7 patients), extravasation of contrast (one patient) pseudoaneurysm (one patient). Bronchial artery embolization was carried out in all patients. Rebleeding occurred within 24 hours in 2 patients who underwent surgery and within one week another 2 patients who were managed with repeat BAE. The complication of embolization occurred in one patient (transverse myelitis). Thirteen patients improved and were discharged home. One patient with terminal lung carcinoma died due to cardiogenic shock secondary to acute myocardial infarction. Bronchial artery embolization is an effective method for management of massive hemoptysis in developing countries and has a low complication rate. (author)

    Background Congenital vascular rings may often cause unexplained respiratory symptoms in infants and young children. Their diagnosis and treatment are often delayed. Few studies of vascular rings have been reported in China.The aim of this study was to describe the clinical presentation, diagnosis and surgical management of infants and children with congenital vascular rings.Methods Clinical histories, physical examinations, investigations, image studies and surgical interventions were retrospectively evaluated in 7 children (age range: 2 months- 4 years, mean 7 months) with congenital vascular rings.Chest radiography was performed in all patients. Echocardiography and computed tomography (CT) with 3-dimensional (3D) reconstructions were performed in 6 patients. Esophagography, cardiac catheterization and angiography, and bronchoscopy were performed in 1, 1 and 4 children, respectively.Results Six of the 7 patients had respiratory symptoms, including recurrent cough, stridor and wheeze. Age at onset of symptoms ranged from 1 month to 11 months. Chest X-ray showed nothing important on the vascular rings, besides bronchitis and pneumonia. Contrast-enhanced CT diagnosed vascular rings in 6 patients. Four patients had double aortic arches, two had balanced arches and two were right arch dominant. One patient had a right aortic arch with left ligament and 1 patient had a pulmonary artery sling. Echocardiography failed to diagnose vascular rings in 2 patients. The esophagogram of 1 patient showed esophageal compression. Bronchoscopy of 4 patients showed compression of the distal trachea. Five of the 7 patients underwent surgical division of the vascular rings. Surgical observation confirmed the CT findings in each patient.Conclusions Patients, especially infants or young children, with recurrent respiratory symptoms such as chronic cough, stridor and wheeze, should be examined for the possible presence of congenital vascular rings.Contrast-enhanced CT can clearly show

    Full Text Available Abstract Background Airway remodelling is a feature of asthma including fragmentation of elastic fibres observed in the superficial elastin network of the airway wall. Fibered confocal fluorescence microscopy (FCFM is a new and non-invasive imaging technique performed during bronchoscopy that may visualize elastic fibres, as shown by in vitro spectral analysis of elastin powder. We hypothesized that FCFM images capture in vivo elastic fibre patterns within the airway wall and that such patterns correspond with airway histology. We aimed to establish the concordance between the bronchial elastic fibre pattern in histology and FCFM. Second, we examined whether elastic fibre patterns in histology and FCFM were different between asthmatic subjects and healthy controls. Finally, the association between these patterns and lung function parameters was investigated. Methods In a cross-sectional study comprising 16 subjects (8 atopic asthmatic patients with controlled disease and 8 healthy controls spirometry and bronchoscopy were performed, with recording of FCFM images followed by endobronchial biopsy at the airway main carina. Elastic fibre patterns in histological sections and FCFM images were scored semi-quantitatively. Agreement between histology and FCFM was analysed using linearly weighted kappa κw. Results The patterns observed in histological sections and FCFM images could be divided into 3 distinct groups. There was good agreement between elastic fibre patterns in histology and FCFM patterns (κw 0.744. The semi-quantitative pattern scores were not different between asthmatic patients and controls. Notably, there was a significant difference in post-bronchodilator FEV1 %predicted between the different patterns by histology (p = 0.001 and FCFM (p = 0.048, regardless of asthma or atopy. Conclusion FCFM captures the elastic fibre pattern within the airway wall in humans in vivo. The association between post-bronchodilator FEV1 %predicted and

    Management of esophago-airway fistulas (EAF) and obstructions often involves therapy with esophageal and/or airway stents. We present a unique approach for the management of EAF and obstructions with simultaneous upper endoscopy and bronchoscopy (two scopes inserted simultaneously through the mouth). The aim is to assess the efficacy and safety of a simultaneous dual scope approach for management of EAF and obstructions. The endoscopy database at the University of Florida was reviewed from October 2007 to April 2012 to identify adult patients who had undergone simultaneous upper endoscopy and bronchoscopy for EAF and obstructions. Medical records were reviewed for demographics, indication, pathology, imaging, simultaneous endoscopic and bronchoscopic findings/maneuvers, outcomes, and adverse events. Outcomes assessed included: (i) technical success, (ii) fistula occlusion, (iii) dysphagia score, and (iv) adverse events. Thirteen patients with EAF and/or obstruction underwent simultaneous dual scope endoscopy. Dual scope procedures were technically successful in 12/13 (92%) patients. Dysphagia score improved from three to one in both patients with dysphagia without EAF. Fistula occlusion was observed in 7/10 patients (70%) with EAF. With this technique, stents were placed accurately without airway compression, migrated esophageal stents extracted from the tracheal lumen without trauma, and tracheal stents not displaced during esophageal manipulations. EAF not otherwise apparent were identified in two patients. Adverse events occurred in 2/13 (15%) patients, and 5/13 (38%) patients died from advanced cancer during follow up (mean 4.1 months, range 1-8 months). Simultaneous dual scope (two scopes inserted through the mouth at the same time) therapy of EAF and obstructions is feasible, effective, and safe, and may develop to be the preferred approach for the management of complex esophago-airway diseases.

  11. Image-based rendering method for mapping endoscopic video onto CT-based endoluminal views

    One of the indicators of early lung cancer is a color change in airway mucosa. Bronchoscopy of the major airways can provide high-resolution color video of the airway tree's mucosal surfaces. In addition, 3D MDCT chest images provide 3D structural information of the airways. Unfortunately, the bronchoscopic video contains no explicit 3D structural and position information, and the 3D MDCT data captures no color or textural information of the mucosa. A fusion of the topographical information from the 3D CT data and the color information from the bronchoscopic video, however, enables realistic 3D visualization, navigation, localization, and quantitative color-topographic analysis of the airways. This paper presents a method for topographic airway-mucosal surface mapping from bronchoscopic video onto 3D MDCT endoluminal views. The method uses registered video images and CT-based virtual endoscopic renderings of the airways. The visibility and depth data are also generated by the renderings. Uniform sampling and over-scanning of the visible triangles are done before they are packed into a texture space. The texels are then re-projected onto video images and assigned color values based on depth and illumination data obtained from renderings. The texture map is loaded into the rendering engine to enable real-time navigation through the combined 3D CT surface and bronchoscopic video data. Tests were performed on pre-recorded bronchoscopy patient video and associated 3D MDCT scans. Results show that we can effectively accomplish mapping over a continuous sequence of airway images spanning several generations of airways.

    We submit the case of a child afflicted with a mucoepidermoid bronchial tumor. The patient is a boy, aged seven, who after undergoing antibiotic treatment for six weeks because of a fever and atelectasia-condensation in the right lower lobe showed no signs of clinical improvement and was sent to our department to undergo further study and treatment. A bronchoscopy performed shows a polypoid mass that partially blocks the main bronchial tube a few milimiters under the access to the right upper lobe. A biopsy is carried out and the anatomopathological test shows there is a low degree epidermoid carcinoma. We decide to perform a lobectomy which for the tumor location and the lung condition has to be medium and lower right. We proceed to remove the adenopaty of hilium not affected by the tumor. The postoperative period develops without incidents. A check-up bronchoscopy performed three months later shows two polypoid masses in the right bronchial tube which, once a biopsy is performed, proved to be granulation tissue. Twelve months after undergoing surgery, the patient's condition is good, there is no evidence of tumor relapse and the breathing capacity is adequate, though there is an obstructive restrictive pattern in the espirometry. Even taking into consideration that lung tumors are extremely unusual, the epidermoid carcinoma is the one which most frequently occurs. The tumor's low malignancy is a sign that points to a good prognosis. Performing conservative surgery by means of bronchoplasty should be taken into account so as to keep the sequelae on the lung condition to a minimum, even though in this case the tumor location made it impossible.

    The pneumolysin (ply) gene is widely used as a target in PCR assays for Streptococcus pneumoniae in respiratory secretions. However, false-positive results with conventional ply-based PCR have been reported. The aim here was to study the performance of a quantitative ply-based PCR for the identification of pneumococcal lower respiratory tract infection (LRTI). In a prospective study, fibreoptic bronchoscopy was performed in 156 hospitalized adult patients with LRTI and 31 controls who underwent bronchoscopy because of suspicion of malignancy. Among the LRTI patients and controls, the quantitative ply-based PCR applied to bronchoalveolar lavage (BAL) fluid was positive at >or=10(3) genome copies/mL in 61% and 71% of the subjects, at >or=10(5) genome copies/mL in 40% and 58% of the subjects, and at >or=10(7) genome copies/mL in 15% and 3.2% of the subjects, respectively. Using BAL fluid culture, blood culture, and/or a urinary antigen test, S. pneumoniae was identified in 19 LRTI patients. As compared with these diagnostic methods used in combination, quantitative ply-based PCR showed sensitivities and specificities of 89% and 43% at a cut-off of 10(3) genome copies/mL, of 84% and 66% at a cut-off of 10(5) genome copies/mL, and of 53% and 90% at a cut-off of 10(7) genome copies/mL, respectively. In conclusion, a high cut-off with the quantitative ply-based PCR was required to reach acceptable specificity. However, as a high cut-off resulted in low sensitivity, quantitative ply-based PCR does not appear to be clinically useful. Quantitative PCR methods for S. pneumoniae using alternative gene targets should be evaluated.

    Full Text Available Background: Auto-fluorescence bronchoscopy (AFB has been used for the identification and localization of intra-epithelial pre-neoplastic and neoplastic lesions within the bronchus. Objectives: To determine the applicability of AFB for the detection and localization of precancerous and cancerous lesions, in addition to analyzing the morphologic presentation, their association to histological type and the variation between genders. Methods: A five-year study involving 4983 patients, who underwent routine bronchoscopy [B] examination in a local tertiary teaching hospital, was done. The B examination was performed under intratracheal lidocaine, and samples were obtained using suitable approach. One thousand four hundred and eighty-five pathologically confirmed lung cancer patients were included in the study. The following parameters were studied: Morphological presentation, biopsy sites, histology. Differences between the groups were analyzed using Chi square test. Result: One thousand four hundred and eighty-five patients who had hyperplasia or neoplastic lesions were further confirmed as lung cancer pathologically. Lung cancer was more commonly found in the right lung (51.58% vs. 42.82%. The lesion occurred more frequently in the upper lobe than the lower lobe (44.17% vs. 22.42%. Male patients with squamous cell carcinoma showed upper lobe involvement more commonly, while the left main bronchus was more commonly involved in female patients. Adenocarcinoma mostly involved lesion of the upper lobe. Squamous cell carcinoma and small cell carcinoma were the major proliferative types (80.15% and 76.16% respectively. Conclusion: AFB is efficient in the detection of pre-invasive and invasive lung lesions. The morphological presentation is associated to the histological type. There is variation in the presentation and histology of cancerous lung lesions between genders.

    Background: In Sweden, there are over 3000 new lung cancer cases every year. There are still numerous patients with undetermined lesions after routine diagnostic evaluation by clinical examination, chest radiography, computed tomography (CT) of the thorax, and bronchoscopy. An appropriate method for further diagnostic workup is therefore needed. Purpose: To evaluate the diagnostic value of the somatostatin analogue depreotide in patients with suspected lung cancer, and to determine in which clinical settings it would be beneficial to use 99mTc-depreotide scintigraphy. Material and Methods: We included 99 consecutive patients referred to our hospital with suspected lung cancer. A clinical examination, bronchoscopy, chest radiography, CT of the thorax and upper abdomen, and scintigraphy were done. Scintigraphy was performed after injection of 740 MBq 99mTc depreotide with tomographical imaging of the thorax and whole-body scanning. The diagnostic outcome of the scintigrams was compared to CT, using morphology or clinical outcome as the endpoint. Results: 99mTc-depreotide uptake was found in 62 out of 66 malignancies, including 57 of 58 primary lung cancer cases. Two cases of lung metastasis (one from a colon cancer and one from an adenoid cystic carcinoma originating in the palate) and one rib chondrosarcoma did not show depreotide uptake. There were 33 patients with benign lesions, of whom 16 displayed false-positive 99mTc-depreotide uptake, whereof 11 were pneumonias. Tc-99m-depreotide uptake was absent in 17 patients with benign lesions, including all 10 hamartomas. The sensitivity in detecting malignancy was 94%, and in detecting lung cancer 98%. The specificity was calculated based on two sets of data. When all cases were used, the specificity was 52%. If the 12 pneumonias are excluded, the specificity was 77%. Conclusion: 99mTc-depreotide scintigraphy has a high sensitivity in detecting lung cancer. The method is useful in decision-making with respect to

    Full Text Available Abstract Background Human airway surface liquid (ASL has abundant antimicrobial peptides whose potency increases as the salt concentration decreases. Xylitol is a 5-carbon sugar that has the ability to lower ASL salt concentration, potentially enhancing innate immunity. Xylitol was detected for 8 hours in the ASL after application in airway epithelium in vitro. We tested the airway retention time of aerosolized iso-osmotic xylitol in healthy volunteers. Methods After a screening spirometry, volunteers received 10 ml of nebulized 5% xylitol. Bronchoscopy was done at 20 minutes (n = 6, 90 minutes (n = 6, and 3 hours (n = 5 after nebulization and ASL was collected using microsampling probes, followed by bronchoalveolar lavage (BAL. Xylitol concentration was measured by nuclear magnetic resonance spectroscopy and corrected for dilution using urea concentration. Results All subjects tolerated nebulization and bronchoscopy well. Mean ASL volume recovered from the probes was 49 ± 23 μl. The mean ASL xylitol concentration at 20, 90, and 180 minutes was 1.6 ± 1.9 μg/μl, 0.6 ± 0.6 μg/μl, and 0.1 ± 0.1 μg/μl, respectively. Corresponding BAL concentration corrected for dilution was consistently lower at all time points. The terminal half-life of aerosolized xylitol obtained by the probes was 45 minutes with a mean residence time of 65 minutes in ASL. Corresponding BAL values were 36 and 50 minutes, respectively. Conclusion After a single dose nebulization, xylitol was detected in ASL for 3 hours, which was shorter than our in vitro measurement. The microsampling probe performed superior to BAL when sampling bronchial ASL.

    Full Text Available BACKGROUND: Multiple independent culture-based studies have identified the presence of Pseudomonas aeruginosa in respiratory samples as a positive risk factor for bronchiolitis obliterans syndrome (BOS. Yet, culture-independent microbiological techniques have identified a negative association between Pseudomonas species and BOS. Our objective was to investigate whether there may be a unifying explanation for these apparently dichotomous results. METHODS: We performed bronchoscopies with bronchoalveolar lavage (BAL on lung transplant recipients (46 procedures in 33 patients and 26 non-transplant control subjects. We analyzed bacterial communities in the BAL fluid using qPCR and pyrosequencing of 16S rRNA gene amplicons and compared the culture-independent data with the clinical metadata and culture results from these subjects. FINDINGS: Route of bronchoscopy (via nose or via mouth was not associated with changes in BAL microbiota (p = 0.90. Among the subjects with positive Pseudomonas bacterial culture, P. aeruginosa was also identified by culture-independent methods. In contrast, a distinct Pseudomonas species, P. fluorescens, was often identified in asymptomatic transplant subjects by pyrosequencing but not detected via standard bacterial culture. The subject populations harboring these two distinct pseudomonads differed significantly with respect to associated symptoms, BAL neutrophilia, bacterial DNA burden and microbial diversity. Despite notable differences in culturability, a global database search of UM Hospital Clinical Microbiology Laboratory records indicated that P. fluorescens is commonly isolated from respiratory specimens. INTERPRETATION: We have reported for the first time that two prominent and distinct Pseudomonas species (P. fluorescens and P. aeruginosa exist within the post-transplant lung microbiome, each with unique genomic and microbiologic features and widely divergent clinical associations, including presence during

  19. Bronchoplasty for Primary Broncho-Pulmonary Tumors

    International Nuclear Information System (INIS)

    Parenchyma-sparing procedures are widely used in patients with low-grade malignancies of the airway when anatomically suited lesions exist. This study was conducted to evaluate the short-term and the long-term results of bronchoplastic procedures for patients with centrally located primary bronchopulmonary tumors. Methods: Between 2000 and 2009, 36 patients with primary lung tumors required bronchoplasty were retrospectively analyzed. Preoperative assessment included computed tomography (CT) of the chest, bronchoscopy, and spirometry. Pre operative diagnosis was achieved by bronchoscopy for all patients, mediastinoscopy was done for patients with primary lung cancer. Neo adjuvant chemotherapy was given for 6 patients with non small cell lung cancer (NSCLC). Results: We had 15 males and 21 female, the mean age was 37 years and the mean hospital stay was 7.2 days. Operative procedures performed were:Sleeve lobectomy in 30 patients (13 right, 17 left), partial sleeve right pneumonectomy in 3 and bronchial resection with re-anastomosis in 3 (2 left, 1 right). Twelve patients (33.3%) suffered post-operative problems. There was one operative related mortality. Post operative pathology revealed: 27 patients with typical carcinoid, 2 with atypical carcinoid, 4 with squamous cell carcinoma, 2 with adenocarcifioma and one with hamartoma. Pathological TNM staging revealed: 17 patients with stage 1A, 11 with IB, 5 with IIA and 2 with stage IIIA. Follow-up data were available for all patients except two. Two patients died with disseminated disease 1.5 year and 2 years after surgery. The patient with hamartoma developed local recurrence 5 years later and re-excision was done. One patient with lung cancer developed bone metastases and was alive with disease, while the remaining 30 patient's were alive and disease free. The overall 5 years survival was 83.3%. Conclusion: Bronchoplastic resections achieve local control and long-term survival comparable to the standard resections in

    Objective: We evaluated the ability of three-dimensional CT to estimate tracheal stenoses in comparison to conventional fiberoptic bronchoscopy, with a view to assist thoracic surgeons in depicting the anatomical characteristics of tracheal strictures. Methods: Spiral CT was performed in 64 patients with suspected tracheal stenoses and in 20 normal subjects. Tracheal stenoses due to an endolu-minal neoplasm were detected in 52 patients, whilst traumatic tracheal stricture was observed in the other 12 patients. Multiplanar reformatting (MPR), volume rendering techniques (VRT) and virtual endoscopy (VE) for trachea evaluation were applied and findings were compared to fiberoptic bronchoscopy. The accuracy of the procedure in describing the localization and degree of stenosis was tested by two radiologists in a blinded controlled trial. Results: The imaging modalities tested showed the same stenoses as the ones detected by flexible bronchoscopy and achieved accurate and non-invasive morphological characterization of the strictures, as well as additional information about the extraluminal extent of the disease. No statistically significant differences were observed between bronchoscopic findings and the MPR, VRT and VE image evaluations (P = 0.715, 0.413 and 0.417 respectively). Conclusion: Three-dimensional CT may provide a high fidelity, noninvasive and reproducible evaluation of the trachea compared to bronchoscopy. They may play a role in assessment of airway patency distal to high-grade stenoses, and represent a reliable alternative method for patients not amenable to conventional bronchoscopy.%目的:我们检测三维CT在气管狭窄的诊断中的作用和纤维支气管镜相比较,用以帮助临床胸外科医生判断气管结构的解剖学特征.方法:对怀疑气管狭窄的患者64例及20例正常病例检查螺旋CT,其中52例发现腔内新生物造成狭窄,另外12例为外伤后狭窄,应用多平面重建(MPR)、容积重建技术(VRT)、仿

    years of age undergoing bronchoscopy due to clinical suspicion of foreign body aspiration at the State University at Campinas Hospital das Clinicas from January of 2000 to December of 2005. RESULTS: The sample consisted of 69 patients, ranging in age from 8 months to 12 years/7 months (75.4% under 3 years of age, 62.3% of whom were male. The principal complaint was sudden-onset cough (75.4%, auscultation was abnormal in 74%, and dyspnea was observed in 29%. Radiological abnormalities were seen in 88% of the cases. Aspirations were primarily into the right lung (54.8%, and 30.7% of the foreign bodies were of vegetal origin (principally beans and peanuts. In the follow-up period, 29% presented complications (most commonly pneumonia, which were found to be associated with longer aspiration time (p = 0.03. Mechanical ventilation was required in 7 children (10.1%, and multiple bronchoscopies were performed in 5 (7.2%. CONCLUSION: A history of sudden-onset choking and cough, plus abnormal auscultation and radiological findings, characterizes the profile of foreign body aspiration. In such cases, bronchoscopy is indicated. Longer aspiration time translates to a higher the risk of complications. The high prevalence of foreign bodies of vegetal origin underscores the relevance of prevention programs aimed at children younger than 3 years of age.

  6. HDR intralumenal brachytherapy in bronchial cancer: review of our experience

    International Nuclear Information System (INIS)

    The main indications for brachytherapy in the treatment of endobronchial cancer are dyspnea. postobstructive pneumonia and atelectasis, cough and hemoptysis resulting from broncus obstruction by exophytic intralumenal tumor growth. High Dose Rate intralumenal brachytherapy (HDRBT) may be combined with external beam radiotherapy (EBRT), in particular as almost all tumors are too large for HDRBT alone. From January 1992 to September 1995 we treated 268 patients affected by bronchial cancer, with EBRT combined with HDRBT. All patients were staged as IIIa-IIIb-IV but KPS was >60 and expectancy of life > than 3 months. After bronchoscopy and Tc simulation we found that almost 10% of patients were downstaged. Treatment was always realized delivering 60 Gy to the tumour volume and 50 Gy to the mediastinal structures with EBRT. Brachytherapy was performed during the radiotherapy course. In 38 patients HDRBT was realized just one time, at the beginning of EBRT, with a dose of 10 Gy calculated at 1cm from the central axis of the catheter. In 47 HDRBT was performed twice (at the beginning and at the end of EBRT) with a dose of 7 Gy calculated at 1 cm from the central axis. From 1994 we started a 3 fractions protocol (Timing: days 1.15.30) with a dose of 5 Gy calculated at 0.5 cm from the axis. Of the 183 patients introduced in the protocol 170 received the three fractions of HDRBT and 13 were excluded from the study for personal or clinical reasons. In 97% of cases the application did not need general anesthesia; local anesthesia has been sufficient supplemented by some drug for sedation and coughing. Anyway both bronchoscopy and HDRBT (with anterior-posterior and lateral chest X-ray) are performed in the same shielded room without the necessity of displacing the patient. In almost 60% of treatments we used just one endobronchial applicator. In case of tumor involvement of the carina, two applicators were introduced. By this a larger tumor volume can be treated with adequate

    Fospropofol is a prodrug of propofol which hydrolyzes in the body by alkaline phosphatase to liberate propofol. Propofol liberated from fospropofol has unique pharmacological properties. Fospropofol in doses of 6.5 or 8 mg/kg, is effective and well tolerated for the sedation of patients undergoing colonoscopy,flexible bronchoscopy. When administered intravenously by a dentist anesthesiologist at the indicated dose, it appearsed to be a safe, well-tolerated alternative to midazolam for intravenous moderate sedation during minor oral surgery procedures. In addition, fospropofol provides safe and effective sedation, rapid time to full alert, and high satisfaction in the elderly subset undergoing flexible bronchoscopy, which is comparable with outcomes in younger patients. Study suggested that fospropofol, administered in an infusion/bolus regimen, be tolerable and effective for short-term induction and maintenance of sedation in intensive care unit patients. Fospropofol also could be used to provide general anesthesia in patients undergoing coronary artery bypass graft surgery.%磷丙泊酚(fospropofol)为丙泊酚的前药,在体内经碱性磷酸酶水解后释放出丙泊酚,释放出来的丙泊酚具有独特的药理性质。安全性与有效性临床试验表明,该药的镇静作用与剂量成正比。磷丙泊酚使用剂量为6.5和8 mg/kg,用于结肠镜检、支气管镜检等内镜检查时镇静,疗效、安全性和耐受性都比较好;使用6.5 mg/kg剂量作为咪达唑仑的替代品用于口腔小手术时既镇静、安全且患者易于耐受。另外,磷丙泊酚用于老年患者支气管纤维镜检,不仅安全有效且患者苏醒快、满意度高,效果与年轻患者相似;采用静脉滴注/推注方式用于ICU患者短期麻醉诱导和镇静作用的维持,耐受性和有效性均可,也可以作为全身麻醉药用于行冠状动脉旁路移植手术患者。

    Purpose: To evaluate the role of chest radiography, single-slice CT and 16-row MDCT in the direct evidence of tracheobronchial injuries. Methods: Patients with acute tracheobronchial injury were identified from the registry of our level 1 trauma center during a 5-year period ending July 2005. Findings at chest radiograph and CT were compared to those shown at bronchoscopy. Results: Eighteen patients with tracheobronchial injury - three patients with cervical trachea injury, eight with thoracic trachea injury and seven with bronchial injury - were identified. Twelve patients had a blunt trauma (67%), six patients had a penetrating (iatrogenic) injury (33%). Chest radiograph directly identified the site of tracheal injury in four cases, showing overdistension of the endotracheal cuff in three cases and displacement of the endotracheal tube in one case. At the level of the bronchi, chest radiograph demonstrated only one injury. CT directly identified the site of tracheal injury in all the cases showing the overdistension of the endotracheal cuff at the level of the thoracic trachea (three cases), posterior herniation of the endotracheal cuff at the thoracic trachea (three cases), lateral endotracheal cuff herniation at the thoracic trachea (one case), tracheal wall discontinuity at the cervical (one case) and at the thoracic trachea (one case) and displacement of endotracheal tube at the cervical trachea (two cases). At the level of the bronchi, CT correctly showed the site of injury in six case including: discontinuity of the left main bronchial wall (two cases), the 'fallen lung' sign (one case), right main bronchial wall enlargement (one case), discontinuity of the right middle bronchial wall (two cases). In one case, CT showed just direct 'air leak' at the level of the carina suggesting main bronchus injury. This finding was confirmed by bronchoscopy. Conclusion: Chest radiograph was helpful for the assessment of iatrogenic tracheal injuries

    Virtual endoscopy of the upper, central and peripheral airways (virtual laryngoscopy or virtual bronchoscopy) produces endoluminal images similar to those of fiberoptic endoscopy. In particular, virtual endoscopy is useful for the assessment of endoluminal tumor extent and tracheobronchial stenosis. Especially since the introduction of multirow detector CT, high-resolution virtual-endoscopic images of the airways can be reconstructed. Either surface rendering or volume rendering can be used for realistic depiction of the airways. Semitransparent color-coded volume rendering is advantageous, because adjacent structures can be displayed in addition to endoluminal views. A major advantage of virtual endoscopy over fiberoptic endoscopy is its non-invasiveness. With virtual endoscopy, even a high-grade stenosis is passable, enabling evaluation of the distal airways. Disadvantages are its inability to depict mucosal color and to perform therapeutic maneuvers. In comparison to other CT display modes, virtual endoscopy allows a more realistic assessment of tracheobronchial stenosis than axial CT slices and multiplanar reformats. Virtual endoscopy of the airways can be used complementary to fiberoptic endoscopy before tracheotomy, stent implantation or lung resection and for post-operative follow-up. In the future, virtual airway endoscopy will be increasingly applied for interactive virtual reality guidance of airway procedures such as bronchoscopy and surgery. (orig.)

    磷丙泊酚(fospropofol)为丙泊酚的前药,在体内经碱性磷酸酶水解后释放出丙泊酚,释放出来的丙泊酚具有独特的药理性质。安全性与有效性临床试验表明,该药的镇静作用与剂量成正比。磷丙泊酚使用剂量为6.5和8 mg/kg,用于结肠镜检、支气管镜检等内镜检查时镇静,疗效、安全性和耐受性都比较好;使用6.5 mg/kg剂量作为咪达唑仑的替代品用于口腔小手术时既镇静、安全且患者易于耐受。另外,磷丙泊酚用于老年患者支气管纤维镜检,不仅安全有效且患者苏醒快、满意度高,效果与年轻患者相似;采用静脉滴注/推注方式用于ICU患者短期麻醉诱导和镇静作用的维持,耐受性和有效性均可,也可以作为全身麻醉药用于行冠状动脉旁路移植手术患者。%Fospropofol is a prodrug of propofol which hydrolyzes in the body by alkaline phosphatase to liberate propofol. Propofol liberated from fospropofol has unique pharmacological properties. Fospropofol in doses of 6.5 or 8 mg/kg, is effective and well tolerated for the sedation of patients undergoing colonoscopy,flexible bronchoscopy. When administered intravenously by a dentist anesthesiologist at the indicated dose, it appearsed to be a safe, well-tolerated alternative to midazolam for intravenous moderate sedation during minor oral surgery procedures. In addition, fospropofol provides safe and effective sedation, rapid time to full alert, and high satisfaction in the elderly subset undergoing flexible bronchoscopy, which is comparable with outcomes in younger patients. Study suggested that fospropofol, administered in an infusion/bolus regimen, be tolerable and effective for short-term induction and maintenance of sedation in intensive care unit patients. Fospropofol also could be used to provide general anesthesia in patients undergoing coronary artery bypass graft surgery.

    2015-01-01

    Full Text Available We describe a case presenting with tracheal tumor wherein a Microlaryngeal tube was advanced into the trachea distal to the tumor for primary airway control followed by cannulation of both endobronchial lumen with 5.5 mm endotracheal tubes to provide independent lung ventilation post tracheal transection using Y- connector attached to anesthesia machine. The plan was formulated to provide maximal surgical access to the trachea while providing adequate ventilation at the same time. A 32 yrs non smoker male, complaining of cough, progressive dyspnea and hemoptysis was diagnosed to have a broad based mass in the trachea on computed tomography of chest. Bronchoscopy of the upper airway confirmed presence of the mass at a distance of 9 cms from the vocal cords, obstructing the tracheal lumen by three fourth of the diameter. The patient was scheduled to undergo the resection of the mass through anterolateral thoracotomy. We recommend the use of extralong, soft, small sized microlaryngeal surgery tube in tumors proximal to carina, for securing the airway before the transection of trachea and bilateral endobronchial intubation with small sized cuffed endotracheal tubes for maintenance of ventilation after the transection of trachea in patients with mass in the lower trachea.

    Full Text Available Abstract Introduction Chronic necrotizing pulmonary aspergillosis is an uncommon subacute form of Aspergillus infection. It typically occurs in immunocompromised individuals and in those with underlying lung disease. This interesting case highlights the occurrence of this entity of aspergillosis in an immunocompetent middle-aged woman with atypical radiological findings. To the best of our knowledge this is the first case report of chronic necrotizing pulmonary aspergillosis presenting with pleural effusion. Case presentation Our patient was a 64-year-old Malay woman with a background history of epilepsy but no other comorbidities. She was a lifelong non-smoker. She presented to our facility with a six-month history of productive cough and three episodes of hemoptysis. An initial chest radiograph showed bilateral pleural effusion with bibasal consolidation. Bronchoscopy revealed a white-coated endobronchial tree and bronchoalveolar lavage culture grew Aspergillus niger. A diagnosis of chronic necrotizing pulmonary aspergillosis was made based on the clinical presentation and microbiological results. She responded well to treatment with oral itraconazole. Conclusions The radiological findings in chronic necrotizing pulmonary aspergillosis can be very diverse. This case illustrates that this condition can be a rare cause of bilateral pleural effusion.

    Lung cancer is the leading cause of death of cancer in Australian men and the third leading cause in Australian women. Efforts are being made to reduce the incidence of this disease by smoking-cessation programmes and improved industrial hygiene, and these measures need to be encouraged strongly by all sectors of the community. On a population basis, insufficient evidence is available to justify screening procedures for the early detection of lung cancer in "at-risk" groups. Cure is possible by surgical resection in early cases. Improvements in therapeutic results with traditional cancer treatments largely have reached a plateau, but a number of newer therapies, and combinations of standard therapies, currently are being evaluated. Of particular interest is concurrent radiotherapy and chemotherapy in localized non-small-cell lung cancer; laser "debulking" in conjunction with radiotherapy in non-small-cell lung cancer, and biological response-modifying agents in non-small-cell and small-cell lung cancer. It is important that data be collected adequately to define epidemiological changes and to evaluate treatment results (including repeat bronchoscopy, to assess local control of tumour), and that the quality of life is recorded and reported in the evaluation process. Finally, phase-III studies in lung-cancer treatments require adequate numbers of subjects to enable meaningful conclusions to be achieve objectives within a reasonable study period. PMID:2469943

    Full Text Available Abstract Background A gastro-tracheal fistula following esophagectomy for cancer is a rare but potentially lethal complication. We report the successful surgical closure after failed endoscopic treatment, of a gastro-tracheal fistula following esophago-gastrectomy for cancer after induction chemo-radiotherapy. Case presentation A 58 year-old male patient presented with a distal third uT3N1 carcinoma of the esophagus. After induction chemo-radiotherapy, he underwent an esophago-gastrectomy with radical lymphadenectomy and reconstruction by gastric pull-up. Immediate postoperative outcome was uneventful. On the 15th postoperative day however, our patient was readmitted in the Intensive Care Unit with severe bilateral basal pneumonia. Three days later a gastro-tracheal fistula was diagnosed upon gastroscopy and bronchoscopy. His good general condition allowed for an endoscopic primary approach which consisted in the insertion of a covered stent in the trachea along with clipping and glueing of the gastric fistular orifice. Two attempts proved unsuccessful. Conclusion After several weeks of conservative measures, surgical re-intervention through a right thoracotomy with transection of the fistula and closure by primary interrupted sutures of both fistular orifices along with intercostal muscle flap interposition led to excellent patient outcome. Oral feeding was started and our patient was discharged.

    Purpose This study investigates the feasibility and potential utility of head-mounted displays for real-time wireless vital sign monitoring during surgical procedures. Methods In this randomized controlled pilot study, surgery residents (n = 14) performed simulated bedside procedures with traditional vital sign monitors and were randomized to addition of vital sign streaming to Google Glass. Time to recognition of preprogrammed vital sign deterioration and frequency of traditional monitor use was recorded. User feedback was collected by electronic survey. Results The experimental group spent 90% less time looking away from the procedural field to view traditional monitors during bronchoscopy (P = .003), and recognized critical desaturation 8.8 seconds earlier; the experimental group spent 71% (P = .01) less time looking away from the procedural field during thoracostomy, and recognized hypotension 10.5 seconds earlier. Trends toward earlier recognition of deterioration did not reach statistical significance. The majority of participants agreed that Google Glass increases situational awareness (64%), is helpful in monitoring vitals (86%), is easy to use (93%), and has potential to improve patient safety (85%). Conclusion In this early feasibility study, use of streaming to Google Glass significantly decreased time looking away from procedural fields and resulted in a nonsignificant trend toward earlier recognition of vital sign deterioration. Vital sign streaming with Google Glass or similar platforms is feasible and may enhance procedural situational awareness. PMID:26848138

    Injuries of the chest isolated or joined with injuries of other organs are distinctly increasing. There are almost no polytraumatic people without thorax injuries. Traffic traumas have a dominant role in causing these injuries. We had most injuries in sammer months. The isolated chest injurie we had 60% and the accompanying injurie 40%. Of the accompanying injuries, the head injurie have the most autstanding place, which especially make difficult the diagnostics, and curing. In heavy injuries of the thorax with paradoxical breathing and on both sides of the leasions, establishing the internal pneumatic stabilisation at the beginning by pulmomatic and then ostheosyntesis of ribs are the most effective therapy. In order to prevent the infections, atracheobronchial dressing with antibiotics is performed as well as the regular X-ray check. As a general rule than 200 ml. per 3 hour requires operative control of the hemorrhage. We had 5,6% thoracothomy after continuous drainage by persstend hemorrhage. The obstructive pneumonia, particularly the eldery are to avoid obstructis, aspiration by catheter with bronchoscopy. PMID:539247

    In this work the authors report two cases of bronchogenic cyst. The first one, in a 69-year-old female patient, with thoracic pain and dyspnea. At the chest X-ray, a mass in the superior mediastinum was observed. Computed tomography of the thorax showed a cystic expansible formation without impregnation by the contrast agent. The patient was referred to thoracic surgery, where she had resected theexpansible formation, that presented histological characteristics of bronchogenic cyst. The other case, in a 50-year-old female patient, that presented symptoms of malaise, retrosternal pain, dry cough, dyspnea and hemoptysis. The chest X-ray evidenced mass in the posterior mediastinum, projected near the helium of the right lung. Computed tomography of the thorax showed a cystic expansible formation, without impregnation by the contrast agent, located in the posterior mediastinum. The patient was submitted to bronchoscopy, videothorascopy and, finally, to thoracotomy, in which the cystic lesion was resected, whose definitive diagnosis, after histopathological examination, was bronchogenic cyst.

    Full Text Available Metastatic prostatic adenocarcinoma presenting as a primary lung disease is rare. We present a 52-year-old male with a 3-month history of cough, shortness of breath, and weight loss with clinical and radiological findings suggestive of a primary lung disease: Bilateral interstitial and alveolar opacities with blunting of the costophrenic angles, multiple diffuse foci of consolidations and nodules, predominantly subpleural and located in the lower lobes, and diffuse interlobular septal thickening and peribronchial thickening. The patient underwent bronchoscopy and bronchoalveolar lavage (BAL was obtained. Cytospin smears were diagnostic for a low-grade adenocarcinoma. Clinically, the patient had elevated serum prostate-specific antigen (PSA levels greater than 5,000 ng/mL. Because of this, immunocytochemistry for PSA was performed which was positive, confirming the diagnosis of metastatic prostatic adenocarcinoma. This unusual case of metastatic adenocarcinoma of the prostate first diagnosed by BAL highlights the significance of available clinical information and the use of immunocytochemistry for proper diagnosis.

    Full Text Available SUMMARY. Pulmonary actinomycosis is a rare, chronic granulomatous disease, which is difficult to diagnose because it is commonly confused with other granulomatous infections or lung cancer. The case is reported of a 48 year-old man, a smoker, who presented with a 30 day history of productive cough with blood tinged sputum and a peripheral lung mass on the chest X-ray. He underwent full clinical and laboratory evaluation including bronchoscopy, which was unrevealing. Because of the haemoptysis the patient refused a computerized tomography (CT guided fine needle aspiration biopsy, and proceeded directly to surgery. Following a right posterolateral thoracotomy and lysis of adhesions, a wedge resection of the right lower lobe mass in the lung was performed and sent for frozen section which was negative for malignancy. His postoperative course was unremarkable. The final pathology report established the diagnosis of pulmonary actinomycosis. Pulmonary actinomycosis should be included in the differential diagnosis of a lung mass in a patient presenting with haemoptysis, because an early and accurate diagnosis will preclude unwarranted surgery.

  7. The cough response to ultrasonically nebulized distilled water in heart-lung transplantation patients

    International Nuclear Information System (INIS)

    As a result of clinical heart-lung transplantation, the lungs are denervated below the level of the tracheal anastomosis. It has been questioned whether afferent vagal reinnervation occurs after surgery. Here we report the cough frequency, during inhalation of ultrasonically nebulized distilled water, of 15 heart-lung transplant patients studied 6 wk to 36 months after surgery. They were compared with 15 normal subjects of a similar age and sex. The distribution of the aerosol was studied in five normal subjects using 99mtechnetium diethylene triamine pentaacetate (99mTc-DTPA) in saline. In seven patients, the sensitivity of the laryngeal mucosa to instilled distilled water (0.2 ml) was tested at the time of fiberoptic bronchoscopy by recording the cough response. Ten percent of the aerosol was deposited onto the larynx and trachea, 56% on the central airways, and 34% in the periphery of the lung. The cough response to the aerosol was strikingly diminished in the patients compared with normal subjects (p less than 0.001), but all seven patients coughed when distilled water was instilled onto the larynx. As expected, the laryngeal mucosa of heart-lung transplant patients remains sensitive to distilled water. However, the diminished coughing when the distilled water is distributed by aerosol to the central airways supports the view that vagal afferent nerves do not reinnervate the lungs after heart-lung transplantation, up to 36 months after surgery

    The report is a retrospective review of 238 benign tracheal stenoses of various etiologies treated between 1995 and 2008. To show that urgent segmental resection has complication rates similar to elective resection and, therefore, preoperative dilation is not necessary, we analysed records of patients who underwent either standard segmental resections with anterolateral mediastinal tracheal mobilization, single-suture anastomosis and neck flexion; or insertion of T-tube with oval-shaped horizontal arm. Primary segmental resection was performed in 164 patients (68.9%), including 14 cases with concomitant tracheo-esophageal fistula (TEF). T-tube as an initial treatment suited 74 (31.1%) patients. We encountered two partial and one complete anastomotic disruptions following subglottic resections treated by T-tube insertion and costal cartilage tracheoplasty or permanent tracheostomy. Restenosis rate in segmental resection was 3.1%. No difference in complication rate between urgent and elective segmental resections was experienced. We treated a small number of patients by endotracheal stent insertion but the results were discouraging. Urgent segmental resection without prior rigid bronchoscopy dilation is our strategy of choice whenever possible. As an alternative to dilation we prefer temporary insertion of modified T-tube. Stand-alone endoluminal dilation and stenting has yet to prove its safety and long-term efficacy. PMID:19755399

  9. Clinical importance of digitized chest X-ray for detection of pulmonary infiltrations in bone marrow transplant patients during aplasia

    International Nuclear Information System (INIS)

    Purpose: Evaluation of digitized chest X-ray for the detection of pulmonary infiltrations in bone marrow transplant patients during aplasia. Methods: Digitized chest X-rays of 40 patients (21 female, 19 male) with 'Fever of unknown origin' (FUO) were evaluated concerning radiological signs of pulmonary infiltrations and correlated to clinical findings, blood chemistry, microbiology and bronchoscopy. Additionally, an individual risk profile was established. Results: In 11/40 patients pulmonary infiltrations were detected in digitized chest X-rays (group 1). 10/11 developed an infectious pulmonary infiltration. 29/40 patients developed no pulmonary infiltration (group 2). When fever increased for the first time (initial chest X-ray) a sensitivity, specificity, positive and negative predictive value of 46%, 86%, 56%, 81% and for the chest X-rays in process of 61%, 79%, 68% and 73% was found. C-reactive protein and temperature increase occured statistically significantly earlier (p<0.05) in group 1 compared to group 2. The average latency of digital chest X-rays in comparison to c-reactive protein and temperature increase was 6 days. The incidence of risk factors was significantly higher in group 1 in comparison to group 2 (p<0.05). Conclusion: Digitized chest X-rays are not a reliable method for primary detection of pulmonary infiltrations after bone marrow transplantation. Individual risk factors have to be taken into consideration to indicate further diagnostic methods such as computed tomography at an earlier time. (orig.)

Most cases are successfully managed with anterior or posterior nasal packing. However, the complications of nasal packing should be always considered. We report the case of a 78-year-old man with Alzheimer’s disease who was treated for anterior epistaxis with anterior nasal packing using three pieces of antibiotic-soaked gauze. Two days later, the patient was admitted to the emergency department in respiratory distress. A chest x-ray demonstrated atelectasis of the right lung. During an examination of the nasal cavities, the nasal packing was removed, and one of the gauze pieces was missing. The patient underwent rigid bronchoscopy, and the missing gauze was found to be obstructing the right main bronchus. The patient’s respiratory function improved considerably after removal of the foreign body. It is assumed that gauze packs should be used with caution in patients with an impaired level of consciousness and neurodegenerative diseases.Keywords: epistaxis, nasal packing, aspiration, Alzheimer’s disease, cough reflex

We performed a retrospective review of clinical, radiological, immunological and microbiological data from 92 non-CF patients with a High resolution thoracic CT (HRCT) diagnosis of bronchiectasis in the three Dublin Children\\'s referral Hospitals for the period 1996-2006. Of 92 patients (50 female), the median age at diagnosis was 6.4 years. The aetiology of bronchiectasis was as follows; idiopathic 29 (32%), post-pneumonia 16 (17%), immune deficiency 15 (16%), recurrent aspiration 15 (16%), primary ciliary dyskinesia 8 (9%), chronic aspiration with immune deficiency 5 (5%), post foreign body inhalation 2 (2%), tracheomalacia 1 (1%) and Obliterative bronchiolitis 1 (1%). Bronchial asthma and gastroesophageal reflux disease (GORD) were concurrently present in 18 (20%) and 10 (11%) respectively. Left lower lobe was commonly involved followed next by the right middle lobe. The common isolates were Haemophilus influenza (50), Streptococcus pneumoniae (34) and Staphylococcus aureus (14), Moraxella catarrhalis (9) and Pseudomonas auerginosa (8). Surgical interventions were performed in 23 (25%) of patients, lobectomy 11 (12%), pneumectomy 2 (2%), laryngeal cleft repair 4 (5%), rigid bronchoscopy for foreign body removal 2 (2%), Nissan\\'s fundoplication 2 (2%), tracheoesophageal fistula repair 2 (2%). We conclude NCFB is under-recognised in Irish children and diagnosis is often delayed and Bronchial Asthma and GORD are common co morbidity. A high index of suspicion and early HRCT can expedite the diagnosis.

    Lung cancer remains the most common cause of cancer-related death in the United States. This study evaluated the costs of alternative diagnostic evaluations for patients with suspected non-small cell lung cancer (NSCLC). Researchers used a cost-minimization model to compare various diagnostic approaches in the evaluation of patients with NSCLC. It was less expensive to use an initial endoscopic ultrasound (EUS) with fine needle aspiration (FNA) to detect a mediastinal lymph node metastasis ($18,603 per patient), compared with combined EUS FNA and endobronchial ultrasound (EBUS) with FNA ($18,753). The results were sensitive to the prevalence of malignant mediastinal lymph nodes; EUS FNA remained least costly, if the probability of nodal metastases was <32.9%, as would occur in a patient without abnormal lymph nodes on computed tomography (CT). While EUS FNA combined with EBUS FNA was the most economical approach, if the rate of nodal metastases was higher, as would be the case in patients with abnormal lymph nodes on CT. Both of these strategies were less costly than bronchoscopy or mediastinoscopy. The pre-test probability of nodal metastases can determine the most cost-effective testing strategy for evaluation of a patient with NSCLC. Pre-procedure CT may be helpful in assessing probability of mediastinal nodal metastases.

    Lipoid pneumonia usually presents after chronic recurrent ingestion of oily substances or accidental aspiration during "fire-eating" demonstrations. Massive exposure by near drowning extremely rare and potentially fatal. We present here a case of survival after total immersion in oil in her workplace. A 66-year-old woman who nearly drowned in a vat of vegetable oil was admitted as an emergency case with severe hypoxia after rescue. Chest computed tomography (CT) findings showed bilateral ground-glass opacity, consolidation, and the case fulfilled the criteria for acute respiratory distress syndrome (ARDS). Bronchoscopy and bronchoalveolar lavage performed on admission indicated oil droplets and marked neutrophilia (67%), which made us diagnose ARDS induced by lipoid pneumonia. We commenced treatment with pulsed steroids and strictly managed fluid balance under mechanical ventilation. Despite immediate improvement in oxygenation, the value of extravascular lung water index (EVLWI) measured by the PiCCO system consistently remained over 30 ml/Kg through her clinical course. We concluded that lipoid pneumonia is characterized by prolonged elevatation of pulmonary vascular permeability.

    Background The aim of this study is to discuss video-assisted thoracic surgery (VATS) sleeve bronchial lobectomy when handling the locally advanced central lung cancer (involving the trachea and/or main bronchus). Methods A 2.5 cm × 1.0 cm mass was found in the right upper lobe. Bronchoscopy demonstrated the tumor obstructing the right upper lobe bronchus and involved the right main bronchus and bronchus intermedius. Interrupted sutures were chosen for bronchial anastomosis. Bronchial membrane was sutured first, and then circumference end-to-end anastomoses were carried out using 3-0 absorbable sutures. Results There were no complications and the patient was discharged 8 days postoperatively. Conclusions The third intercostal space of the anterior axillary line was suggested for right upper lobe bronchial sleeve resection. This incision can reduce the distance and angle between the anastomosis to the incision, and facilitate anastomosis. This approach can also prevent operator from fatigue for keeping one posture for a long time. Clearance of the mediastinal lymph nodes before cutting the bronchus was helpful for exposing the right main bronchus, the upper lobe bronchus and bronchus intermedius satisfied. And this option would avoid pulling bronchial anastomosis during mediastinal lymph nodes clearance. Interrupted suture was safe and effective for VATS bronchial anastomosis. PMID:27621889

    We assessed the sensitivity of positron emission tomography (PET) for detecting synchronous multiple primary cancers, particularly synchronous esophageal cancers in head and neck cancer patients. We retrospectively reviewed 230 head and neck cancer patients. All the patients routinely underwent the following examinations: urinalysis, occult blood, tumor marker detection [squamous cell carcinoma (SCC), cytokeratin fragment (CYFRA), and carcinoembryonic antigen (CEA)], esophagogastroduodenoscopy, colonoscopy (when CEA was high or occult blood was positive), abdominal ultrasonography, plain chest computed tomography (CT), and PET. Bronchoscopy was performed when CT revealed lung shadow of central region. Synchronous multiple primary cancers were detected in 42 (18.2%) patients. The diagnostic sensitivity of PET for synchronous primary cancers was as follows: esophagus, 7.6% (1/13); stomach, 25.0% (2/8); lung, 66.7% (4/6); head and neck, 75.0% (3/4); colon, 0% (0/1); kidney, 0% (0/1); and subcutaneous, 100% (1/1). The sensitivity of PET for detecting synchronous esophageal cancers is low because these are early-stage cancers (almost stage 0-I). Therefore, it is necessary to perform esophagogastroduodenoscopy for detecting synchronous esophageal cancers. PET is an important additional tool for detecting synchronous multiple primary cancers because the diagnostic sensitivity of PET in synchronous head and neck cancer and lung cancer is high. But PET has the limitation of sensitivity for synchronous multiple primary cancers because the diagnostic sensitivity of PET in synchronous esophageal cancer is very low.

    Pneumocystis pneumonia is a life threatening infection that usually presents with diffuse bilateral ground-glass infiltrates in immunocompromised patients. We report a case of a single nodular granulomatous Pneumocystis pneumonia in a male with diffuse large B-cell lymphoma after R-CHOP therapy. He presented with symptoms of productive cough, dyspnea, and right-sided pleuritic chest pain that failed to resolve despite treatment with multiple antibiotics. Chest X-ray revealed right lower lobe atelectasis and CT of chest showed development of 2 cm nodular opacity with ground-glass opacities. Patient underwent bronchoscopy and biopsy that revealed granulomatous inflammation in a background of organizing pneumonia pattern with negative cultures. Respiratory symptoms resolved but the solitary nodular opacity increased in size prompting a surgical wedge resection which revealed granulomatous Pneumocystis pneumonia infection. This case is the third documented report of Pneumocystis pneumonia infection within a solitary pulmonary nodule in an individual with hematologic neoplasm. Although Pneumocystis pneumonia most commonly occurs in patients with HIV/acquired immunodeficiency syndrome and with diffuse infiltrates, the diagnosis should not be overlooked when only a solitary nodule is present.

    The spread of computed tomography (CT) brought the frequent further examinations of the solitary pulmonary nodules (SPN). To aim the evaluation of initial data on examinations of SPN for differential diagnosis, we studied retrospective cases. Thirty-one cases of SPN less than 20 mm in diameter were compared in clinical findings and CT image findings and were examined the diagnostic procedures in recent three years in National Sanyo Hospital. The 31 patients consisted of 14 males and 17 females ranging 44 to 79 years old, median 65 years old. The causes of SPN were lung cancer (11 patients), cryptococcosis (4 patients), tuberculoma (3 patients), non-tuberculous mycobacteria (2 patients), pneumoconiosis (2 patients), pneumonia scar (one patient), hamartoma (one patient), and unknown (7 patients). There were no significant differences in laboratory findings between lung cancer and the others. CT findings showed significant differences in four categories. All patients underwent fiberoptic bronchoscopy (FB) examinations and 12 patients were determined the diagnosis initial FB. Five patients were established their diagnosis using videoassociated thoracoscopic surgeries. (author)

    Full Text Available Abstract Background Left main bronchus resection and reconstruction (LMBRR is a complex surgical procedure indicated for management of inflammatory, benign and low grade malignant lesions. Its application provides maximal parenchymal sparing. Methods Out of 98 bronchoplastic procedures performed at the Authors' Institution in the 1995-2011 period, 4 were LMBRR. Indications were bronchial carcinoid in 2 cases, inflammatory pseudotumor in 1 case, TBC stricture in 1 case. All patients underwent preoperatively a rigid bronchoscopy to restore the airway lumen patency. At surgery a negative resection margin was confirmed by frozen section in the neoplastic patients. In all patients an end-to-end bronchial anastomosis was constructed according to Grillo. Results There were neither mortality nor major complications. Airway lumen was optimal in 3 patients, good in 1. Conclusion LMBRR is a valuable option for the thoracic surgeon. It maximizes the parenchyma-sparing philosophy, broadening the spectrum of potential candidates for cure. It remains a technically demanding procedure, to be carried out by an experienced surgical team. Correct surgical planning affords excellent results, both in the short and long term.

    Lung cancer has remained the leading cause of death worldwide among all cancers. The dismal 5-year survival rate of 16% is in part due to the lack of symptoms during early stages and lack of an effective screening test until recently. Chest X-ray and sputum cytology were studied extensively as potential screening tests for lung cancer and were conclusively proven to be of no value. Subsequently, a number of studies compared computed tomography (CT) with the chest X-ray. These studies did identify lung cancer in earlier stages. However, they were not designed to prove a reduction in mortality. Later trials have focused on low-dose CT (LDCT) as a screening tool. The largest US trial – the National Lung Screening Trial (NLST) – enrolled approximately 54,000 patients and revealed a 20% reduction in mortality. While a role for LDCT in lung cancer screening has been established, the issues of high false positive rates, radiation risk, and cost effectiveness still need to be addressed. The guidelines of the international organizations that now include LDCT in lung cancer screening are reviewed. Other methods that may improve earlier detection such as positron emission tomography, autofluorescence bronchoscopy, and molecular biomarkers are also discussed. PMID:26528348

    Full Text Available Background: About 100,000 Iranian have been exposed to chemical weapons during Iraq-Iran conflict (1980-88. After being spent of more than two decades, still about 30,000 of them are under follow-up treatment. The main aim of this study was to review various preventive and therapeutic methods for injured patients with sulfur mustard in different phases. Methods: For gathering information, we have used the electronic databases including Scopus, Medline, ISI, IranMedex, Irandoc sites. According to this search strategy, 104 published articles associated to respiratory problems and among them 50 articles related to prevention and treatment of respiratory problems were found and reviewed. Results: There is not any curative treatment for sulfur mustard induced lung injuries, but some valuable experienced measures for prevention and palliative treatments are available. Some useful measures in acute phase include: Symptomatic management, oxygen supplementation, tracheostomy in laryngospasm, use of moist air, respiratory physical therapy, mucolytic agents and bronchodilators. In the chronic phases, these measures include: Periodic clinical examinations, administration of inhaled corticosteroids alone or with long-acting beta 2 agonists, use of antioxidants, magnesium ions, long term oxygen supplement, therapeutic bronchoscopy, laser therapy, and use of respiratory tract stents. Conclusions: Most treatments are symptomatic but using preventive points immediately after exposure could improve following outcomes.
