Nondisseminated histoplasmosis of the trachea

Histoplasma capsulatum can rarely affect the trachea. We report the case of a 68-year-old woman with rheumatoid arthritis on immunosuppressive therapy who presented with fevers, worsening shortness of breath, nonproductive cough and subjective throat hoarseness and fullness. Chest computed tomography demonstrated no tracheal findings. Bronchoscopy found mucosal irregularity, nodularity and vesicular regions in the proximal trachea extending seven centimeters distal to the vocal cords. Also seen was an edematous, exudative left vocal cord with polyps and an ulcerative lesion. Silver staining and culture and wash of the tracheal biopsy revealed Histoplasma capsulatum. She was treated with oral itraconazole then briefly on intravenous amphotericin for rising Histoplasma urinary antigen levels. She continued treatment 24 months following diagnosis with minimal dyspnea. Histoplasma tracheitis has been proposed as an indicator of disseminated infection. However, our patient did not demonstrate other organ manifestations. Histoplasma tracheitis should be considered in a differential diagnosis of tracheal lesions even in the absence of systemic involvement.

The use of convex probe endobronchial ultrasound-guided transbronchial needle aspiration in a pediatric population: a multicenter study

INTRODUCTION

The presence of intrathoracic lymphadenopathy and mediastinal masses in the pediatric population often presents a diagnostic challenge. With limited minimally invasive methodologies to obtain a diagnosis, invasive sampling via mediastinoscopy or thoracotomy is often pursued. Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive, outpatient procedure that has demonstrated significant success in the adult population in the evaluation of such abnormalities. Within the pediatric literature there is limited data regarding the use of EBUS-TBNA. We report the first multicenter review of a pediatric population undergoing EBUS-TBNA procedures identifying the feasibility, safety, utility, and outcomes of this procedure.

METHODS

All patients of 18 years of age or younger undergoing EBUS-TBNA at six major academic medical centers from the years 2007 through 2013 were reviewed. Data regarding procedural performance, outcomes, and complications were recorded.

RESULTS

A total of 21 patients meeting the inclusion criteria were identified in six centers. The mean age of the cohort was 13.7 (±4.1) years. EBUS-TBNA provided adequate sampling in 20/21 (95%) of the cases with diagnostic material obtained in 10 (48%) cases. Eight patients (38%) underwent additional surgical procedures to confirm or obtain diagnostic tissue. Within our cohort, 13 patients (62%) were able to avoid invasive surgical biopsy procedures. No procedural or anesthesia related complications were identified.

CONCLUSION

We report the first multicenter study to date confirming the feasibility and utility of EBUS-TBNA in the pediatric population. Due to the low overall procedural risk of EBUS-TBNA, it should be considered as a potential first line diagnostic option for children presenting with mediastinal or hilar abnormalities but further prospective studies are needed.

Unanticipated difficult nasotracheal extubation following oral surgery

Difficult tracheal extubation is a rare but potentially dangerous problem that can be life threatening especially when it is unexpected and there is a lack of preparation. Most of these cases are associated with orofacial surgery. We herein present two patients with oral cavity cancer who experienced unexpected postoperative difficult nasotracheal extubation by a Kirschner pin penetrating the endotracheal tube and fixing the tube at the maxillary bone following tumor resection. The pins were found by fiberoptic bronchoscopy. Both patients were returned to the operating theater immediately for removal of the penetrating pins as well as the endotracheal tubes. The common causes of difficult tracheal extubation and strategies of managing these situations are discussed in the article.

Comparison of two 22 G aspiration needles for histologic sampling during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA)

OBJECTIVE

Endobronchial ultrasound-guided transbronchial needle aspiration is widely used for mediastinal and hilar lesions. Histologic specimens from this procedure are important for specific diagnosis and targeted therapy. Studies on the traditional endobronchial ultrasound-guided transbronchial needle aspiration needles reported yields of only 50-60% for diagnostic histologic specimens. Recently, a new needle has become available in Europe, USA and Asia. The investigators aimed to evaluate the histologic specimen retrieval yields of the two needles.

METHODS

Patients who underwent endobronchial ultrasound-guided transbronchial needle aspiration with the new 22 G needle (M group, n = 94) were compared with a historical control group who underwent endobronchial ultrasound-guided transbronchial needle aspiration with the traditional 22 G needle (O group, n = 82). The quality of needle aspirates from both groups was evaluated.

RESULTS

There were no significant differences between the two groups in terms of demographics, lesion characteristics, primary disease and examiner experience. The M group had a significantly shorter procedure time than the O group (P = 0.049). Of the 214 punctures by the M group, 159 (74.3%) were diagnostic, 28 (13.1%) were non-diagnostic and 27 (12.6%) had no histologic specimen. The 235 punctures by the O group were diagnostic in 144 (61.3%), non-diagnostic in 60 (25.5%) and had no histologic specimen in 31 (13.2%). The yield for diagnostic histologic specimens of the M group was significantly higher than the O group (P = 0.0035). There were no major complications observed.

CONCLUSIONS

The yield for diagnostic histologic specimens by the new 22 G endobronchial ultrasound-guided transbronchial needle aspiration needle was high. Further technical improvements of histologic sampling yields are very important when selecting targeted therapy.

Endobronchial chondromas

Endobronchial chondromas are rare benign tumors. They may be part of the Carney triad; however, isolated endobronchial chondromas can occur in the larynx, trachea, and bronchi. We report a case of an endobronchial chondroma in a 61-y-old man with an incidental 5-mm endobronchial polypoid lesion at the proximal left main bronchus that was later found to be an endobronchial chondroma. Flexible bronchoscopy demonstrated a pedunculated, vascularized, pink mass. An excisional biopsy revealed a well-circumscribed lesion with nodular areas of mature cartilage and myxoid tissue confirmatory of an endobronchial chondroma. We reviewed a total of 23 cases of isolated endobronchial chondromas reported in the medical literature. Despite their rarity, endobronchial chondromas should be considered in the differential diagnosis of endobronchial tumors. Prompt recognition and resection of endobronchial chondromas is important to prevent airway obstruction and its associated complications.

Novel bronchoscopic strategies for the diagnosis of peripheral lung lesions: present techniques and future directions

The diagnosis of the peripheral lung lesion has been a long-standing clinical challenge--balancing accuracy with patient safety. With recent data revealing mortality benefits with lung cancer screening via low-dose computed tomography, now more than ever, 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 nodule. In this review, we present available technologies to aid clinicians in attempts at minimally invasive techniques and the data supporting their use. In addition, we review novel tools under investigation that may further increase yield and provide additional benefit in obtaining an early diagnosis of lung cancer.

A plastic whistle incarcerated in bronchus diagnosed fourteen years after 'swallowed': a case report

Tracheobronchial foreign body aspiration (FBA) is a common disease in pre-school children but easily overlooked by physicians. In this article, we report a case with bronchial stenosis that is not typical and misdiagnosed for 14 years, in the end bronchoscopy retrieval was successfully performed after adequate preparation. Pitfalls and recommendations in diagnosis and management of FBA are briefly included.

Airway trauma: a review on epidemiology, mechanisms of injury, diagnosis and treatment

Airway injuries are life threatening conditions. A very little number of patients suffering air injuries are transferred live at the hospital. The diagnosis requires a high index of suspicion based on the presence of non-specific for these injuries symptoms and signs and a thorough knowledge of the mechanisms of injury. Bronchoscopy and chest computed tomography with MPR and 3D reconstruction of the airway represent the procedures of choice for the definitive diagnosis. Endotracheal intubation under bronchoscopic guidance is the key point to gain airway control and appropriate ventilation. Primary repair with direct suture or resection and an end to end anastomosis is the treatment of choice for patients suffering from tracheobronchial injuries (TBI). The surgical approach to the injured airway depends on its location. Selected patients, mainly with iatrogenic injuries, can be treated conservatively as long as the injury is small (<2 cm), a secure and patent airway and adequate ventilation are achieved, and there are no signs of sepsis. Patients with delayed presentation airway injuries should be referred for surgical treatment. Intraoperative evaluation of the viability of the lung parenchyma beyond the site of stenosis/obstruction is mandatory to avoid unnecessary lung resection.

Elective tracheostomy in intensive care unit: Looking between techniques, a three cases report

There is no optimal tracheostomy (TS) technique, proved to be the best. For this reason, operators’ skills, clinical anatomical and physio-pathological features of the patient should be considered as discriminating factors in the choice of percutaneous dilation tracheostomy (PDT) technique. This article includes reports of three cases of PDT: In the first case distance between jugular notch and the first tracheal ring was too long, the second case involving a patient with mild ectasia of the ascending aorta and aortic regurgitation with De Musset's sign with great risk of perioperative bleeding and a third case, of tracheomalacia with inflammatory stenosis at the 4^th tracheal ring. All together, this case series describes how decisions were made by an experienced staff, in which the patient characteristics were assessed and techniques best suited for each case were implemented.

Endobronchial ultrasound for peripheral lesions: a review

Lung cancer is one of the most common tumors worldwide. Pulmonary lesions detected during screening for lung cancer need to be evaluated further and tissue should be obtained. Bronchoscopy is often the first step to secure a histological diagnosis. Differ-ent guidance techniques are available to increase the diagnostic yield. Over the last few years endobronchial ultrasound (EBUS) has been used increasingly to direct the sampling tools, often in combination with a guide sheath. This article offers a review of the literature of the use of EBUS in diagnosis of pulmonary peripheral lesions.

Diagnostic bronchoscopy--current and future perspectives

Lung cancer is the leading cause of cancer-related mortality worldwide. Standard bronchoscopy has limited ability to accurately localise and biopsy pulmonary lesions that cannot be directly visualised. The field of advanced diagnostic bronchoscopy is rapidly evolving due to advances in electronics and miniaturisation. Bronchoscopes with smaller outer working diameters, coupled with miniature radial and convex ultrasound probes, allow accurate central and peripheral pulmonary lesion localisation and biopsy while at the same time avoiding vascular structures. Increases in computational processing power allow three-dimensional reconstruction of computed tomographic raw data to enable virtual bronchoscopy (VB), providing the bronchoscopist with a preview of the bronchoscopy prior to the procedure. Navigational bronchoscopy enables targeting of peripheral pulmonary lesions (PPLs) via a "roadmap", similar to in-car global positioning systems. Analysis of lesions on a cellular level is now possible with techniques such as optical coherence tomography (OCT) and confocal microscopy (CM). All these tools will hopefully allow earlier and safer lung cancer diagnosis and in turn better patient outcomes. This article describes these new bronchoscopic techniques and reviews the relevant literature.

Characteristics and risk factor analysis of 410 cases of tracheobronchial tuberculosis

The present study analyzed the characteristics and risk factors associated with tracheobronchial tuberculosis (TBTB) in 410 patients with TBTB. Retrospective analysis was performed on the clinical features, bronchoscopy performance, bacteriological examination, imaging and treatment of 410 patients who were diagnosed with TBTB using bronchoscopy. Among the 410 patients, 10 patients underwent chest X-ray which revealed two cases of atelectasis, eight cases of patch or spot shadows, three cases of cavity, one case of nodule and one case with no abnormalities. The remaining 400 patients underwent computed tomography chest scans and/or airway reconstruction examinations. Among all the lesion types, the cavity type was found to be the most likely to cause bronchial stenosis or obstruction, with statistically significant differences when compared with the congestion, stenosis or scar lesion types (P<0.01). Moreover, for the cavity type, there were 194 sites of obstruction prior to therapy; however, only 23 sites of obstruction remained following therapy. Furthermore, there were 34 sites without stenosis prior to therapy and 205 sites without stenosis following therapy. The number of sites of obstruction was significantly decreased and the number of sites without stenosis was increased upon therapy. These findings suggest that the cavity type is the most sensitive type to therapy among the five types of TBTB lesion.

Fibrotic airway stenosis following radiotherapy in patients with adenoid cystic carcinoma

BACKGROUND AND OBJECTIVE

Radiotherapy is usually administered to the central airway in patients with unresectable adenoid cystic carcinoma (ACC). The purpose of this study was to describe the outcomes of endobronchial intervention in patients with airway stenosis following radiotherapy for ACC. Moreover, we investigated the incidence and contributing factors for airway stenosis following radiotherapy for ACC.

METHODS

Forty-seven patients with ACC, who underwent radiotherapy of the tracheobronchial tree from January 1995 to December 2011, were reviewed retrospectively. Fibrotic airway stenoses were diagnosed using three-dimensional computed tomography, flexible bronchoscopy or both.

RESULTS

Eleven (23%) of the 47 patients with ACC suffered fibrotic airway stenosis following radiotherapy and received bronchoscopic intervention. The median interval from radiotherapy to diagnosis of fibrotic airway stenosis was 7 months. Low forced expiratory volume in 1 s (FEV1), FEV1 /forced vital capacity and brachytherapy were verified as factors contributing to radiotherapy-induced airway stenosis. Bronchoscopic intervention provided both symptomatic relief and improvement of lung function, and no procedure-related death or major complication was observed. Insertion of a straight silicone stent was required in 10 patients (91%), and 4 (36%) eventually received Y-shaped silicone stents. The stents, once implanted, could not be removed in any of the patients; stents were well-tolerated for a prolonged period in all patients.

CONCLUSIONS

Fibrotic airway stenosis following radiotherapy in patients with ACC is often found. Bronchoscopic intervention, including silicone airway stenting, was a safe and useful method for treating radiotherapy-induced fibrotic airway stenosis in patients with ACC.

Comparative study of ex vivo probe-based confocal laser endomicroscopy and light microscopy in lung cancer diagnostics

BACKGROUND AND OBJECTIVE

Probe-based confocal laser endoscopy (pCLE) allows for real-time non-invasive histological imaging via bronchoscopy. Interpreting CLE images and correlating with traditional histopathology remains challenging. We performed an ex vivo study to evaluate the correlation between light microscopy findings and pCLE imaging of primary lung carcinoma.

METHODS

Post-lobectomy specimens for lung cancer nodules were examined ex vivo by pCLE. The examined areas were marked with brilliant green dye, and the surrounding tissues were stained by methylene blue dye. Lung tissue segments were resected and histopathological specimens were generated with 50-μm thickness from the marked areas and stained with haematoxylin and eosin. Pathologists and pulmonologists reviewed the images for correlating features.

RESULTS

Eighteen lobectomy specimens from 18 different patients were collected. Three primary features were observed in all samples using pCLE in the cancer surroundings: alveolar dystelectasis with thickening of alveolar walls, alveolar edema and a large amount of macrophages. The stromal and parenchymal components of the studied subtypes of non-small-cell lung cancer differed from each other. The stromal component for all nine adenocarcinoma specimens had a highly fluorescent field penetrated by dark hollows. All six squamous cell carcinoma specimens had the stromal component appeared as 'biparously' branching, highly fluorescent fibres. No stromal component was observed in any small-cell carcinoma specimen, and at low power field, the cellular component was dominant with an observed light scattering pattern.

CONCLUSIONS

pCLE can identify lung carcinoma in ex vivo samples. Certain light microscopy features of lung carcinoma can be visualized with pCLE.

A case of accidental aspiration of an endodontic instrument by a child treated under conscious sedation

Dental management of children with attention-deficit hyperactivity disorder (ADHD) often requires the need for pharmacological behavior management techniques such as the use of sedation. The purpose of this article is to describe a clinical case involving accidental aspiration of an Endodontic instrument during root canal therapy under sedation. To our knowledge, this is the first case report of aspiration of an Endodontic instrument and should serve to heighten the awareness with regard to aspiration during dental procedures under sedation. It also emphasizes the need for proper isolation techniques in patients treated under sedation, thereby preventing such complications.

Diagnostic yield of transbronchial cryobiopsy in interstitial lung disease: a randomized trial

BACKGROUND AND OBJECTIVE

Transbronchial lung biopsy (TBLB) is required for evaluation in selected patients with interstitial lung disease (ILD). The diagnostic yield of histopathologic assessment is variable and is influenced by factors such as the size of samples and the presence of crush artefacts left by conventional biopsy forceps. We compared the diagnostic yield and safety of TBLB with cryoprobe sampling versus conventional forceps sampling.

METHODS

This randomized clinical trial analysed data for 77 patients undergoing TBLB for evaluation of ILD; patients were assigned to either a conventional-forceps group or a cryoprobe group. Two pathologists assessed the tissue samples and agreed on histopathologic diagnoses. We also compared the duration of procedures, complications and sample-quality variables.

RESULTS

The most frequent diagnosis observed in the cryoprobe group was non-specific interstitial pneumonia. Histopathologic diagnoses were identified in more cases in the cryoprobe group (74.4%) than in the conventional-forceps group (34.1%) (P < 0.001), and the diagnostic yield was higher in the cryoprobe group (51.3% vs 29.1% in the conventional forceps group; P = 0.038). A larger mean area of tissue was harvested by cryoprobe (14.7 ± 11 mm(2) ) than by conventional forceps (3.3 ± 4.1 mm(2)) (P < 0.001). More grade 2 bleeding (not statistically significant) occurred in the cryoprobe group (56.4%) than in the conventional-forceps group (34.2%). No differences in other complications were observed.

CONCLUSIONS

TBLB by cryoprobe is safe and potentially useful in the diagnosis of ILD. Larger multisite randomized trials are required to confirm the potential benefits of this procedure. Clinical trial registration at ClinicalTrials.gov: NCT01064609.

Histological changes after radiation therapy in patients with lung cancer: a prospective study

BACKGROUND

Radiotherapy for lung cancer may induce pneumonitis. However, histological effects of radiotherapy on normal lung tissue are unknown. Transbronchial biopsy (TBB) is safe and accurate in monitoring parenchymal lesions in lung-transplanted patients. The aim of this prospective study was to evaluate whether histological changes of the healthy lung parenchyma after radiotherapy are present on TBB biopsies.

PATIENTS AND METHODS

Twelve patients with lung cancer necessitating radiation therapy participated in the study. Serial TBBs were obtained from lung parenchyma contra-lateral to the tumor before, just after radiotherapy, and at six months post-irradiation. Evaluation of each specimen was based on the presence of congestion, inflammation, hemorrhage and fibrosis.

RESULTS

A significant increase of interstitial fibrosis (thickness) and congestion was observed between the point prior to radiotherapy and after completion of radiotherapy (p=0.047), as well as between the pre-radiotherapy point and at six months after radiotherapy (p=0.014). Six patients (50%) showed intra-alveolar fibroblastic growth after radiotherapy. No patient showed clinical or radiographic findings of radiation pneumonitis.

CONCLUSION

Even in the absence of clinical or radiographic findings, the lung parenchyma contra-lateral to the tumor suffers early histological lesions after radiation therapy, as monitored by serial TBBs.

Postsplenectomy left lower lobe bronchiectasis

BACKGROUND

Bronchiectasis has decreased significantly. I describe a new underestimated clinicopathological entity of postsplenectomy left lower lobe bronchiectasis.

METHODS

This is a retrospective study on 24 patients who had a left lower lobectomy for left lower lobe bronchiectasis after splenectomy. The mean age was 34.6 years (range 18 to 63 years); there were 19 men and 5 women. The available data included history, radiological investigations (ultrasonography and computed tomography of the chest and abdomen), operative data, postoperative complications, and follow-up data.

RESULTS

All patients had a history of splenectomy and 10 had undergone subphrenic collection drainage either percutaneously or through open drainage a few years prior to the left lower lobectomy. Fourteen patients were lost to follow-up. The mean follow-up in 10 patients was 5.8 years (range 2 to 13 years).

CONCLUSIONS

Postsplenectomy left lower lobe bronchiectasis is an underestimated clinicopathological entity of bronchiectasis. It can be managed by a left lower lobectomy, with acceptable results.

Management of aspirated tooth in an adult head injury patient: Report of two cases

Aspiration of foreign bodies is common in a pediatric age group but adults can also be at risk. We describe management of two adult trauma victims with aspirated tooth. In the first case, foreign body went missing for sometime by intensive care physician and detected by radiologist while it was obvious in the second case. Both the patients were managed with the help of rigid bronchoscopy. Tooth should be removed as soon as possible or it may result in complete airway obstruction or lung collapse.

Diagnostic yield of bronchial washing fluid analysis for hemoptysis in patients with bronchiectasis

PURPOSE

Bronchiectasis is the main cause of hemoptysis. When patients with bronchiectasis develop hemoptysis, clinicians often perform bronchoscopy and bronchial washing to obtain samples for microbiological and cytological examinations. Bronchial washing fluids were analyzed from patients with bronchiectasis who developed hemoptysis, and the clinical impacts of these analyses were examined.

MATERIALS AND METHODS

A retrospective observational study of patients who underwent fiberoptic bronchoscopy for hemoptysis in Seoul National University Bundang Hospital, a university affiliated tertiary referral hospital, between January 2006 and December 2010 were reviewed. Among them, patients who had bronchiectasis confirmed by computed tomography and had no definite cause of hemoptysis other than bronchiectasis were reviewed. The demographic characteristics, bronchoscopy findings, microbiological data, pathology results and clinical courses of these patients were retrospectively reviewed.

RESULTS

A total of 130 patients were reviewed. Bacteria, non-tuberculous mycobacteria (NTM), and Mycobacterium tuberculosis were isolated from bronchial washing fluids of 29.5%, 21.3%, and 0.8% patients, respectively. Suspected causal bacteria were isolated only from bronchial washing fluid in 19 patients, but this analysis led to antibiotics change in only one patient. Of the 27 patients in whom NTM were isolated from bronchial washing fluid, none of these patients took anti-NTM medication during the median follow-up period of 505 days. Malignant cells were not identified in none of the patients.

CONCLUSION

Bronchial washing is a useful method to identify microorganisms when patients with bronchiectasis develop hemoptysis. However, these results only minimally affect clinical decisions.

Significance of new lung infiltrates in outpatients after lung and heart-lung transplantation

Background

Infection and rejection represent major complications following lung transplantation and are often associated with pulmonary infiltrates. The differential diagnosis of these infiltrates depends on their timing after transplantation. The aim of this study was to characterize lung transplant recipients (LTR) presenting with new pulmonary infiltrates.

Methods

A retrospective analysis of all LTR and heart–lung transplant recipients attending outpatient follow‐up at our institution between September 1, 2006 and October 14, 2011 was performed. All patients presenting with new pulmonary infiltrates on chest x‐ray who underwent bronchoscopy were included.

Results

A total of 913 patients accounted for 13,156 attendances, with 3,912 bronchoscopies being performed. Seventy‐eight patients (9%) exhibited new pulmonary infiltrates and proceeded to bronchoscopy. Infiltrates occurred at a median 15 (interquartile range [IQR] 5–39) months after transplantation. Forty‐eight patients (62%) were male, and median patient age was 47 (IQR 29–57) years. Subsequent investigation revealed pneumonia to be the underlying cause in 63 patients (81%). In the remaining patients, chronic lung allograft dysfunction (CLAD) was responsible in 6 (8%), acute rejection in 5 (6%), and toxic pneumonitis in 4 (5%) patients. Overall 1‐year survival in LTR presenting with new infiltrates was 97%, compared with 96% for all LTR attending our Outpatient Department.

Conclusions

New pulmonary infiltrates occurring after the first month in LTR are most likely due to infection. Through prompt diagnosis and treatment, early mortality appears unaffected. Late mortality remains attributable to CLAD.

"Diesel siphoner's lung": Exogenous lipoid pneumonia following hydrocarbon aspiration

Lipoid pneumonia is an unusual and uncommon form of pneumonia caused by aspiration of fatty substances. Hydrocarbon pneumonitis following aspiration of diesel is a form of exogenous lipoid pneumonia wherein, aspirated diesel reaches the alveoli rapidly without evoking any significant cough, but initiates an intense inflammatory reaction in the pulmonary parenchyma. This is a rarely described clinical scenario, although the practice of diesel siphonage from automobiles is a common practice in developing countries. We herein describe a 40-year-old male patient, in whom the diagnosis of lipoid pneumonia was delayed for a long duration and highlight the importance of taking a detailed occupational exposure history in patients with non-resolving pneumonia to rule out the underlying possibility of this rare clinical entity.

Therapeutic rigid bronchoscopy at a tertiary care center in North India: Initial experience and systematic review of Indian literature

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.
