[PMID: 37473440 DOI: 10.1002/ohn.433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Revised: 06/22/2023] [Accepted: 07/08/2023] [Indexed: 07/22/2023]
Abstract
OBJECTIVE The goal of this study is to evaluate the sensitivity and specificity of computed tomography (CT) scans in the diagnosis of foreign body aspiration (FBA) in children, and to determine whether chest CT scans would reduce the need for diagnostic rigid bronchoscopies. DATA SOURCES MEDLINE, EMBASE, Scopus, and the Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched for relevant articles and conference proceedings that were published in English through November 1, 2022. REVIEW METHODS We included prospective and retrospective studies comparing chest CT scans and rigid bronchoscopy for the diagnosis of FBA in pediatric patients (<16 years old). The pooled estimates of the sensitivity and specificity of the chest CT scan in the diagnosis of FBA were calculated using a fixed- or common-effects analysis and a random-effects analysis that accounts for heterogeneity if present. Forest plots were constructed to combine the evidence identified during the systematic review. RESULTS Eighteen articles (4178 patients) were included. The average age of the children was 2.26 (±0.75) years, and 65% (±5.64%) of them were boys. Cough was the most prevalent symptom upon presentation. The pooled analysis showed that the sensitivity of chest CT scan in detecting a foreign body in children was 99% (95% confidence interval, CI [97, 100]; I2 = 72%, τ2 = 0.0065, p < .01). The false negative rate was 1.8% (95% CI [0.3, 2.7]; I2 = 72%, p < .01). The specificity of chest CT scan was 92% (95% CI [83, 98]; I2 = 83%, τ2 = 0.0437, p < .01). CONCLUSIONS Chest CT scan is a sensitive and specific test for the diagnosis of FBA in the pediatric population. Its use can help to reduce unnecessary rigid bronchoscopies, especially in patients with a low clinical suspicion of aspiration. It should not be a replacement for the gold standard bronchoscopy, particularly in cases where there is a clear history and symptoms suggestive of aspiration.

Abstract
BACKGROUND Tracheobronchial foreign body aspiration is a classic pediatric emergency, and its associated morbidity particularly depends on the anesthetic management, which differs according to the center and the practitioner. AIMS The aim of this study was to evaluate the different anesthetic practices for tracheobronchial foreign body extraction. METHODS A survey was sent via email to the member physicians of the Association des Anesthésistes Réanimateurs Pédiatriques d'Expression Française (ADARPEF). The survey included 28 questions about the organizational and anesthetic management of an evolving clinical case. RESULTS A total of 151 physicians responded to the survey. Only 13.2% of the respondents reported that their institution had a management protocol, and 21.7% required a computerized tomography scan before the procedure was performed for children who were asymptomatic or mildly symptomatic during the night. There were 56.3% of the respondents who reported that extraction with a rigid bronchoscope is the only procedure usually performed in their institution. Regarding rigid bronchoscopy, 47.0% used combined intravenous-inhalation anesthesia. The objective was to maintain the child on spontaneous ventilation for 63.6% of the respondents, but anesthesia management differed according to the physician's experience. CONCLUSIONS Our study confirms the diversity of practices concerning anesthetic for tracheobronchial foreign body extraction and found reveal differences in practice according to physician experience.

Abstract
INTRODUCTION Rigid bronchoscopy remains the gold standard for the diagnosis of foreign body aspiration (FBA) despite high rates of negative bronchoscopies. The use of computed tomography (CT) imaging in the assessment of FBA has recently emerged and could help obviate unnecessary bronchoscopy in these patients. The aim of this study is to assess the diagnostic accuracy of CT in the diagnosis of pediatric FBA. METHODS A systematic literature review was conducted to identify studies reporting the use of CT imaging in suspected pediatric FBA. The search included published articles in Ovid MEDLINE, Ovid EMBASE, PubMed MEDLINE and Web of Science. The search strategy included all articles from inception of the database to January 2021. Manuscripts were reviewed and graded for quality using the QUADAS-2 tool. Subgroup analyses based on the use of virtual bronchoscopy (VB) and sedation was conducted. A meta-analysis evaluating the use of VB in the diagnosis of FBA was also conducted. RESULTS Sixteen manuscripts met all inclusion criteria. In total, 2056 pediatric patients ranging from 0.3 to 15 years underwent CT for suspected FBA. The sensitivity and specificity of CT were 98.8% and 96.6%, respectively. VB was used in 71.4% (1391/1948) of patients while sedation during CT was required in 70.2% (1263/1800) of patients. Radiation dosing ranged from 0.04 to 2 mSv, 0.99-59.1 mGy-cm and 0.03-16.99 mGy. CONCLUSION CT can accurately diagnose pediatric FBA and can help decrease the rate of unnecessary bronchoscopies with an acceptable dose of radiation.

Abstract
Introduction:
Foreign body aspiration is a commonly encountered and challenging emergency. Foreign body aspiration causes significant morbidity and mortality in the paediatric population. In adults, it is usually encountered in patients with impaired consciousness and in young females using pins to secure their veils. We aimed to analyse the incidence, type and site of foreign body, radiological presentation, complications and different modalities used in managing tracheobronchial foreign bodies (FBs).
Methods:
A prospective single centre cross-sectional study between December 2010 and December 2011 in the Department of Cardiothoracic Surgery at the University of Alexandria, Egypt.
Results:
Seventy-eight patients were included. The age of the patients ranged between 1.3 and 32 years, with a mean of 13.37± 7.67 years. Inorganic FBs were the most common aspirated FBs (66 patients, 84.62%). FBs were more frequently located in the left versus the right bronchial tree (44.9% vs. 43.6%). Rigid bronchoscopic extraction of foreign bodies was the most common modality of extraction and was seen in 60 patients (76.9%), followed by thoracotomy and postural drainage in eight patients each (10.3%). Complications were observed in 12 patients (15.4%). Most of the patients who presented with pin aspiration were teenagers (> 10 – 20 years) and adults (> 20 years). At the same time, nut aspiration was common in children below 10 years.
Conclusion:
The location of FBs in the tracheobronchial tree depends on the patient's age and physical position at the time of aspiration. Rigid bronchoscopy offers better manipulations inside a secured airway and is the preferred method for foreign body removal. If failed, then surgical extraction should be done as soon as possible.

Abstract
Foreign body ingestion should be considered as an important differential in a child with difficult asthma. We report an 11-year-old male child with foreign body aspiration who initially was diagnosed and treated as difficult asthma. Later on, he was diagnosed to have a foreign body in the right bronchus, which was successfully removed by flexible bronchoscopy.

Abstract
Diagnosis of an airway foreign body in the setting of an unwitnessed aspiration event remains a challenge for physicians in the emergency setting. We describe a case of a 2-year-old male who presented to the emergency department with atypical symptoms resulting from ingestion and aspiration of a large, flat sticker. The airway foreign body remained in place for over 24 hours despite obtaining appropriate airway imaging, and the object was later removed without complication via rigid bronchoscopy in the operating room. Further review of this case and the current literature highlighted multiple lessons. Initial evaluations should combine a rigorous history and physical with strict guidelines on usage of multiple imaging modalities (eg, plain radiographs and CT). Imaging should be obtained with the patient devoid of all obstructive materials in multiple positions (eg, upright, supine, lateral) in order to maximize the physician's ability to positively diagnose airway foreign bodies prior to definitive treatment with rigid bronchoscopy.

Abstract
Background Incidence of foreign body aspiration has been noticed predominantly in age group ranging from 12 months-3 years. Foreign body in the trachea is a medical emergency as presentation is in respiratory distress. Obstruction of only one main or distal bronchus, leads to severe cough, choking sensation and breathlessness. Without early intervention, it can lead to collapse, consolidation and pneumonia of the affected lung. Methods We retrospectively analyzed 37 pediatric case records who presented from January 2014–December 2018 with foreign body aspiration. Our primary aim was to assess the parameters responsible for early and late diagnosis of foreign body aspiration. We concluded with a diagnostic algorithm for management of foreign body aspiration on the basis of this outcome. Results Around 32.5% came with a history of aspiration, 43% were referred from the primary centers with a suspicion for the same and the rest came to our tertiary care hospital directly. Those who presented within a week came with complaints of wet cough, wheeze and tachypnea. Furthermore, those who came in after a week had a dry cough and fever as their main complaint. Majority of ingested foreign bodies was a vegetative type (80%) as compared to the non –vegetative. Conclusion Unlike adults, foreign body aspiration in children is most commonly diagnosed on history, suspicion and clinical findings. Chest x ray has been the primary investigation of choice but in the majority of the cases it was normal with subtle changes. Early diagnosis is the key to avoid complication.

Abstract
PURPOSE Suspected airway foreign body aspiration (FBA) is a common event in paediatric emergency units, especially in children under 3 years of age. It can be a life-threatening event if not diagnosed promptly and accurately. The purpose of this study is to compare the diagnostic performance of an ultralow-dose CT (DLP of around 1 mGycm) with that of conventional radiographic methods (fluoroscopy and chest radiography of the airways) in the diagnosis of FBA children's airways. METHODS Retrospective cross-sectional study. Data from 136 children were collected: 75 were examined with conventional radiographic methods and 61 with ultralow-dose CT. Effective doses were compared using independent t tests. The results of bronchoscopy, if performed, were used in creating contingency 2 × 2 tables to assess the diagnostic performance between modalities. An extra triple reading of all images was applied for this purpose. RESULTS The effective doses used in the ultralow-dose CT examinations were lower compared with those in conventional methods (p < 0.001). The median dose for CT was 0.04 mSv compared with 0.1 mSv for conventional methods. Sensitivity and specificity were higher for ultralow-dose CT than those for conventional methods (100% and 98% versus 33% and 96%) as were the positive and negative predicted values (90% and 100% versus 60% and 91%). CONCLUSION Ultralow-dose CT can be used as the imaging of choice in the diagnosis of airway FBA in emergency settings, thereby avoiding concerns about radiation doses and negative bronchoscopy outcomes.

Abstract
BACKGROUND Bronchoscopy is the standard of care for diagnosis and treatment of foreign body aspiration (FBA). Drawbacks of this approach include its invasiveness, the potential for exacerbation of reactive airway disease, and the need for general anesthesia. Computed tomography (CT) can potentially identify patients with FBA, thereby avoiding unnecessary bronchoscopies in patients with at-risk reactive airways. METHODS A retrospective review was performed to identify patients who underwent CT and/or bronchoscopy for suspected foreign body aspiration (FBA) from June 2012 to September 2018. Variables included clinical history, exam findings, radiographic findings, and operative findings. A telephone survey was performed for patients who had a CT without bronchoscopy. Three radiologists performed rereads of all CTs. RESULTS A total of 133 patients were evaluated for FBA, and 84 were treated with bronchoscopy. For those with a CT demonstrating a foreign body, findings were confirmed on bronchoscopy in 17/18 (94.4%). For those with bronchoscopy alone, 39/64 (60.9%) were found to have a foreign body (p < 0.01). CT excluded FBA in 49 patients. Sensitivity was 100%, specificity was 98%, and interobserver reliability was excellent (κ = 0.88). CONCLUSION CT is an accurate and reliable diagnostic tool in the evaluation of FBA that can increase the rate of positive bronchoscopy. TYPE OF STUDY Retrospective comparative study. LEVEL OF EVIDENCE Level III.

Abstract
Foreign body inhalation is a clinical emergency requiring prompt action to ensure speedy recovery and minimize the development of complications. It is more common in children than adults. We report a case of a neglected foreign body present in the bronchus of an adult for 23 years and treated as intermittent asthma. The diagnosis was revealed following the development of severe sepsis of a pulmonary origin. The foreign body was removed by rigid bronchoscopy, antibiotic therapy instituted and pre- and post-interventional respiratory physiotherapy carried out. Satisfactory progress was marked by the complete clearing of pulmonary suppuration, with only a small localized and asymptomatic focus of bronchial dilatation remaining. The persistence of chronic, unexplained respiratory complaints should prompt the use of imaging and endoscopy to exclude an endobronchial cause, especially to consider the possible presence of a previously unknown foreign body. Early diagnosis and intervention can help to avoid potentially serious complications.

Abstract
OBJECTIVE This study sought to summarize the clinical characteristics of foreign body aspiration(FBA) in children with negative multi-detector Computed Tomography(MDCT) results and to explore the essential points which determined the patients to undergo bronchoscopy. METHODS The medical records of 48 pediatric patients admitted to the department of respiratory medicine in our hospital from January 2011 to October 2018 and diagnosed with foreign body aspiration and negative chest MDCT results were retrospectively analyzed. They were compared with the patients of FBA whose MDCT findings suggested indirect signs, such as atelectasis or emphysema. RESULTS Of the 48 patients, 33 were boys (68.8%) and 15 girls (31.2%), with a mean age of 35.3 months(range, 7-156 months). Cough (47 cases, 97.9%), fever (25 cases, 52.1%) and wheezing (23 cases,47.9%)were the main symptoms.39 patients (81.3%) had abnormal physical signs. None of the MDCT or three dimension(3D) images based on MDCT revealed foreign bodies in these children, while the results were: signs of lung infection without atelectasis or emphysema 52.1%(25 cases), increase of lung markings16.7%(8 cases),bronchiectasis 6.3%(3 cases), or normal 27.1%(13 cases). 41 Patients were successfully removed their foreign bodies(A further 5 had the FB removed from the tracheobronchial tree but it was then swallowed before retrieval. The remaining 2 cases had to be referred to another hospital for further management), most of which were organic. The shapes of foreign bodies were small granular (23 cases, 56.1%), sheet or powder (18 cases, 43.9%). The control group was 13 patients of FBA whose MDCT findings suggested indirect signs of atelectasis or emphysema during the same time. The result of comparison showed the clear history of FBA was statistically different between the two groups. CONCLUSIONS Foreign body aspiration could not be ruled out with negative MDCT in patients clinically suspected. Typical foreign body aspiration history and ineffective conservative treatment could provide important basis of performing bronchoscopy. Complicated with lung infection and the shape of foreign bodies may affect the false negative results of MDCT.

Abstract
Airway foreign bodies are a leading cause of death among children and require urgent recognition by medical personnel. While most cases are diagnosed readily from a clinical history of acute respiratory distress, some cases remain more indolent and present later. We report the case of a 7-year-old boy who aspirated a "LEGO" toy and presented with a week history of increasing respiratory distress compatible with known asthma. Despite a normal chest X-ray, a low-dose computed tomography showed the presence of a foreign body in the left main bronchus, which was subsequently removed by fiberoptic bronchoscopy. Our case serves to reemphasize the importance of considering airway foreign bodies as a cause of respiratory distress, especially in young children.

Abstract
Tracheobronchial foreign body (FB) aspiration is an uncommon but potentially life-threatening event in adults. Symptoms typically consist of a choking event followed by cough and dyspnea, however, these findings are inconsistent and symptoms may mimic more chronic lung diseases such as asthma or chronic obstructive pulmonary disease. Chest radiography and computed tomography can provide information regarding the location and characteristics of foreign bodies and aid in diagnosis. Bronchoscopy remains the gold standard for diagnosis and management of FB aspiration. The authors describe the typical clinical presentation, diagnostic evaluation, and bronchoscopic management of foreign bodies in adult airways with a focus on bronchoscopic techniques and potential complications of FB extraction.

Abstract
INTRODUCTION Flexible bronchoscopy (FB) is the current gold standard for diagnosing tracheobronchomalacia. However, it is not always feasible and virtual bronchoscopy (VB), acquired from chest multi-detector CT (MDCT) scan is an alternative diagnostic tool. We determined the sensitivity, specificity, and positive and negative predictive values of VB compared to FB in diagnosing tracheobronchomalacia. METHODS Children aged <18-years scheduled for FB and MDCT were recruited. FB and MDCT were undertaken within 30-min to 7-days of each other. Tracheobronchomalacia (mild, moderate, severe, very severe) diagnosed on FB were independently scored by two pediatric pulmonologists; VB was independently scored by two pairs (each pair = pediatric pulmonologist and radiologist), in a blinded manner. RESULTS In 53 children (median age = 2.5 years, range 0.8-14.3) evaluated for airway abnormalities, tracheomalacia was detected in 37 (70%) children at FB. Of these, VB detected tracheomalacia in 20 children, with a sensitivity of 54.1% (95%CI 37.1-70.2), specificity = 87.5% (95%CI 60.4-97.8), and positive predictive value = 90.9% (95%CI 69.4-98.4). The agreement between pediatric pulmonologists for diagnosing tracheomalacia by FB was excellent, weighted κ = 0.8 (95%CI 0.64-0.97); but only fair between the pairs of pediatric pulmonologists/radiologists for VB, weighted κ = 0.47 (95%CI 0.23-0.71). There were 42 cases of bronchomalacia detected on FB. VB had a sensitivity = 45.2% (95%CI 30.2-61.2), specificity = 95.5% (95%CI 94.2-96.5), and positive predictive value = 23.2 (95%CI 14.9-34.0) compared to FB in detecting bronchomalacia. CONCLUSION VB cannot replace FB as the gold standard for detecting tracheobronchomalacia in children. However, VB could be considered as an alternative diagnostic modality in children with symptoms suggestive of tracheobronchomalacia where FB is unavailable.

Abstract
It is unusual but not uncommon for foreign bodies to be missed at bronchoscopy. This case report highlights the importance of the clinical history in the diagnosis of aspirated foreign bodies and the usefulness of chest imaging modalities. A 6-year-old boy presented with recurrent breathlessness and cough of 2 months. He was said to have aspirated the base cap of a pen at about the time symptoms started. He had two sessions of rigid bronchoscopy and a session of flexible bronchoscopy at three different hospitals. He had an initial rigid bronchoscopy which failed to show the foreign body (FB). A chest computerized tomographic scan demonstrated the FB, which was retrieved at combined flexible/rigid bronchoscopy. Although rigid bronchoscopy is the gold standard for managing airway foreign bodies, there remains a false negative rate for this procedure and where necessary, appropriate imaging may compliment rigid bronchoscopy, especially where there is some confusion.

Abstract
Abstract
In diagnosing the aspiration of the foreign body (AFB) in children most important are: medical history, clinical signs and positive radiography of the lungs. Common dilemmas in the diff erential diagnosis are life-threatening asthma attacks or difficult pneumonia. Conventional rigid bronchoscopy (RB) is not recommended as a routine method. Virtual bronchoscopy (VB) can be a diagnostic tool for solving dilemmas. Fiber-optic bronchoscopy (FOB) has a therapeutic stake in severe cases. Herein, we describe a girl, at the age of 6, who was hospitalized due to rapid bronchoconstriction and based on the anamnesis, clinical symptoms and physical fi ndings the suspicion was that she aspirated the foreign body. Due to the poor general condition and possible sequel, the idea of RB was dropped out. Multidetector computed tomography of the chest and VB was performed and AFB was not found. Due to positive epidemiological situation, virus H1N1 was excluded. FOB established that the foreign body does not exist in the airways. During bronchoscopy numerous castings are aspirated from the peripheral airways which lead to faster final recovery. With additional procedures, the diagnosis of asthma was confirmed and for girl that was the first attack. Along with inhaled corticosteroids as prevention she feels well.
Virtual bronchoscopy can be successfully used as a valid diagnostic procedure in suspected foreign body in the children’s lungs, but fiber-optic bronchoscopy remains most important diagnostic and therapeutic method.

Abstract
Respiratory emergencies are 1 of the most common reasons parents seek evaluation for the their children in the emergency department (ED) each year, and respiratory failure is the most common cause of cardiopulmonary arrest in pediatric patients. Whereas many respiratory illnesses are mild and self-limiting, others are life threatening and require prompt diagnosis and management. Therefore, it is imperative that emergency clinicians be able to promptly recognize and manage these illnesses. This article reviews ED diagnosis and management of foreign body aspiration, asthma exacerbation, epiglottitis, bronchiolitis, community-acquired pneumonia, and pertussis.

Abstract
A toddler presented with a 5-month history of recurrent episodes of cough, wheezing and fever. Before referral, the toddler had been initially diagnosed as having bronchial asthma and later as having pulmonary tuberculosis. On examination, the patient was febrile and had severe respiratory distress. Chest radiograph and high-resolution CT of the chest revealed collapse of the entire left lung with diffuse bronchiectasis along with a grossly hyperinflated right lung. CT virtual bronchoscopy did not reveal any foreign body. The parents denied any history suggestive of foreign body aspiration and refused consent for rigid bronchoscopy. Nine days after admission, chest physiotherapy was inadvertently prescribed to the patient. Within an hour, the patient experienced acute respiratory deterioration and died. Autopsy revealed a piece of betel nut in the right main bronchus; it had got dislodged from its initial site in the left main bronchus following the chest physiotherapy session.

Abstract
Chest X-ray in a 17-year-old boy, presenting with haemoptysis, revealed a radiopaque foreign body (FB) in the right lower lobe. There was no history of aspiration. CT located the needle-shaped FB in the right posterobasal lower lobe segment bronchus. In bronchoscopy, the FB turned out to be a pin, of which the radiolucent plastic head was embedded in the peribronchial tissue. Extraction by flexible and rigid bronchoscopy failed; finally, thoracotomy and bronchotomy had to be performed to remove the pin. In delayed diagnosis of a tracheobronchial FB, CT scan is not only necessary to localise the FB but also to depict or rule out secondary pulmonary changes. Nevertheless, radiolucent components of a metallic FB might be invisible even in CT, leading to underestimation of its size and extension. Late diagnosis complicates removal of tracheobronchial foreign bodies and may even necessitate open surgery, including pulmonary resections.

Abstract
BACKGROUND Foreign body aspiration is common and potentially life threatening. Although rigid bronchoscopy has the potential for serious complications, it is the 'gold standard' of diagnosis. It is used frequently in light of the inaccuracy of clinical examination and chest radiography. Computed tomography is proposed as a non-invasive alternative to rigid bronchoscopy. OBJECTIVE This study aimed to evaluate the accuracy and safety of computed tomography used in the diagnosis of suspected foreign body aspiration, and compare this with the current gold standard, in order to examine the possibility of using computed tomography to reduce the number of diagnostic rigid bronchoscopies performed. METHOD The study comprised a review of literature published from 1970 to 2013, using the PubMed, Scopus, Web of Knowledge, Embase and Medline electronic databases. RESULTS The sensitivity for computed tomography ranged between 90 and 100 per cent, with four studies demonstrating 100 per cent sensitivity. Specificity was between 75 and 100 per cent. Radiation exposure doses averaged 2.16 mSv. CONCLUSION Computed tomography is a sensitive and specific modality in the diagnosis of foreign body aspiration, and its future use will reduce the number of unnecessary rigid bronchoscopies.

Abstract
OBJECTIVE To evaluate the sensitivity of multidetector computed tomography for confirming suspected foreign body aspiration into the airways in children. METHOD We conducted a multicentre prospective study of 303 children evaluated using multidetector computed tomography with axial analysis complemented by multiplanar reconstruction when required. The images were read by a radiologist before endoscopy then reviewed later by a senior radiologist blinded to the endoscopy findings. Endoscopy was performed routinely. RESULTS Foreign bodies were found by endoscopy in 70 of the 303 children. The initial multidetector computed tomography reading was 94% sensitive and 95% specific. For the review, the images for 91 patients were excluded because of motion blurring or absence of larynx visualisation; in the remaining 212 patients, sensitivity was 98% and specificity 97%. CONCLUSION Multidetector computed tomography as performed in our patients cannot replace endoscopy, which remains the reference standard. Nevertheless, multidetector computed tomography is sufficiently sensitive to be of value when foreign body aspiration is not considered initially or when endoscopy is likely to prove challenging.

Abstract
Background: Since introduction of multislice CT scanners into clinical practice, virtual brochoscopy has gained a lot of quality and diagnostic potential. Nevertheless it does not have established place in diagnostics of tracheal and bronchi disorders and its potential has not been examined enough. Nowadays a majority of bronchial tree variants and lesions are revealed by bronchofiberoscopy, which is an objective and a relatively safe method, but has side effects, especially in higher-risk subjects. Therefore noninvasive techniques enabling evaluation of airways should be consistently developed and updated. Material/Methods: Material consisted of 100 adults (45 female, 55 male) aged between 18 and 65 years (mean 40 years, median 40.5 years, SD 14.02), who underwent chest CT examination by means of a 16-slice scanner. Every patient had normal appearance of chest organs, with the exception of minor abnormalities that did not alter airways route. Divisions of bronchial tree to segmental level were evaluated and assigned to particular types by means of virtual bronchoscopy projection. In case of difficulties MPR or MinIP projection was used. Results: The frequency of lobar bronchi divisions other than the typical ones was in: right upper lobar bronchi 45%, left 55%; middle lobar bronchi 21%, lingula 26%; right lower lobar bronchi 28%, left 29%. Subsuperior bronchus or bronchi were found on the right side in 44% and on the left side in 37%. No dependency between types of bronchial divisions on different levels was found.

Abstract
To evaluate the value of 3D images based on multi-detect computer tomography (MDCT) for the diagnosis and management of patients with suspected foreign bodies aspiration, and report our experience about diagnosis and management of the aforementioned patients using the 3D images, as well as detail our protocol for the management of those patients. Forty-four patients (37 children, 7 adults) with suspected foreign bodies aspiration who accepted pre-surgical examination and bronchoscopy in our hospital were included in this study. All the patients' pre-surgical 3D images based on MDCT were reconstructed and analyzed. After that all the results were compared with observations in the surgeries. Among the 37 pediatrics, 34 patients were detected with FB in their tracheobronchial system by the 3D images based on MDCT, and 3 cases were detected negative. The sensitivity of 3D images is 100 %, and the specificity is 75 %.In the adult group, all the 7 cases of FB in the tracheobronchial tree were detected by 3D images and proved by bronchoscopy. 3D images based on MDCT were proved to be a valuable method for the diagnosis of the patients with suspected FB aspiration. In the diagnosis and management of those patients, we considered that both the typical FB aspiration history and the intractable symptoms of cough should be taken as the criteria and the first step for selecting those suspected patients; then 3D images based on MDCT could be taken as the second step and as the selective criteria for those patients who should accept the rigid bronchoscopy.

Abstract
OBJECTIVE This study sought to summarize the experience of diagnosis and treatment of tracheobronchial foreign bodies in children to effectively reduce complications and mortality. METHODS The medical records of 1024 pediatric patients admitted to our hospital from January 1997 to September 2011 and diagnosed with clinically suspected tracheobronchial foreign body aspiration were retrospectively analyzed. RESULTS Of the 1024 children patients, 674 were boys (65.8%) and 350 girls (34.2%). Two died of respiratory and circulatory failure (foreign bodies detected upon bronchoscopy but not retrieved) before surgery, 65 patients underwent direct bronchoscopic removal of foreign bodies due to their critical status, and 957 received chest radiographs and chest fluoroscopy or multidetector spiral computed tomographic scans (941 positive). Foreign bodies were expectorated before surgery in 3 cases. There were 953 cases of bronchoscopically proven airway foreign body aspiration, with a diagnostic accuracy of 94.5%. Ninety-eight foreign bodies were lodged in the main bronchus and/or bilateral bronchi, 506 in the right main bronchus, and 349 in the left main bronchus. Atelectasis was noted in 42 patients, including 11 with pulmonary consolidation, whose lungs were re-expanded by endobronchial lavage and sputum aspiration. In 3 patients with bronchiectasis, conservative treatment following foreign body removal was followed by no improvement, and pulmonary lobectomy was performed. Foreign bodies were successfully extracted at the first bronchoscopic attempt in 948 cases, accounting for 99.7% of the total. However, 3 patients had to undergo another bronchoscopy to remove the foreign bodies. The most common types of foreign bodies were peanuts, melon seeds, and beans. CONCLUSIONS Timely accurate diagnosis and treatment of tracheobronchial foreign bodies in children can avoid delay in treatment and effectively reduce complications and mortality.

Abstract
BACKGROUND Very recently, some attempts have been made to start a systematic collection of foreign bodies (FB) in view of using them to characterize the risk of chocking in terms of size, shape and consistency of the FB. However, most of the epidemiologic evidence on foreign bodies in children comes from single-center retrospective studies, without any systematic geographical and temporal coverage. This paper is aimed at providing an estimate of the distribution of foreign body's injuries in children according to gender, age, type of FB, site of obstruction, clinical presentation, diagnostic/therapeutic procedures, complications, as emerging from a meta-analytic review of published papers. METHODS A free text search on PubMed database ((foreign bodies) OR (foreign body)) AND ((aspiration) OR (airways) OR (tracheobronchial) OR (nasal) OR (inhalation) OR (obstruction) OR (choking) OR (inhaled) OR (aspirations) OR (nose) OR (throat) OR (asphyxiation)) AND ((children) OR (child)) finalized to identify all English written articles referring to foreign body inhalation over a 30 years period (1978-2008) was performed. The target of the analysis has been defined as the proportion of injuries as reported in the studies, stratified according to children demographic characteristics, type of FB, site of obstruction. The pooled proportions of FB were calculated using the DerSimonian and Laird approach. RESULTS 1699 papers were retrieved and 1063 were judged pertinent; 214 English written case series were identified, among them 174 articles were available and have been included in the analysis. Airway foreign body most commonly occurs in young children, almost 20% of children who have inhaled foreign bodies being between 0 and 3 years of age. Organic FB, particularly nuts, are the most documented objects while, among inorganic FBs, the greatest pooled proportion has been recorded for magnets, which can be particularly destructive in each location. Non specific symptoms or a complete absence of symptoms are not unusual, justifying mistaken or delayed diagnosis. Acute and chronic complications seem to occur in almost 15% of patients. CONCLUSIONS Even if an enormous heterogeneity among primary studies seems to exist and even if the absence of variables standardized definitions across case series, including class age definition and symptoms and signs descriptions, seriously impairs studies comparability, our results testify the relevant morbidity associated with foreign body inhalation in children, stressing the importance of preventive measures.

Questioning the legitimacy of rigid bronchoscopy as a tool for establishing the diagnosis of a bronchial foreign body. Int J Pediatr Otorhinolaryngol 2012; 76:194-201. [PMID: 22154779 DOI: 10.1016/j.ijporl.2011.11.002] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2011] [Revised: 10/31/2011] [Accepted: 11/01/2011] [Indexed: 12/31/2022]
Abstract
OBJECTIVES Rigid bronchoscopy (RB) is the principal method used for the extraction of a tracheo-bronchial foreign body (FB), but its use as a diagnostic tool implies a certain rate of negative exams, exposing the child to the risk of procedure and anesthesia-related complications. Technological progress has improved the accuracy and availability of non-invasive modalities, such as CT scan and fluoroscopy. Our aim is to review our experience in the routine use of bronchoscopy for a suspected FB aspiration, and evaluate the adequacy of our current attitude in light of these alternatives. METHODS We performed a retrospective review of cases where bronchoscopy was used in the management of a suspected airway FB, and analysis of the correlation between the clinical and radiological data and the bronchoscopy's results. In addition we reviewed the literature concerning the use of RB and alternative means of diagnosis such as CT scan, fluoroscopy and flexible bronchoscopy. RESULTS Thirty-two patients underwent bronchoscopy to rule out a FB aspiration under general anesthesia. No FB was found in 8 cases (25%). Cough and a history of choking were the most sensitive parameters (sensitivity 100% and 80% respectively), but had a low specificity. Stridor was the most specific sign (88% specificity), but was not sensitive. Chest radiography had 25% sensitivity, and 62.5% specificity. Flexible bronchoscopy changed the management in 22% of cases, sparing RB. CONCLUSIONS Basing the decision to perform RB solely on the clinical findings and chest radiography entails a 25% rate or more of negative exams. CT scan appears to be the most accurate non-invasive tool for ruling out the presence of a FB but its use cannot be systematic due to its complexity and the risks of exposure to radiation. Digital substraction fluoroscopy is a safe and simple mean to confirm the presence of air trapping generated by a bronchial obstruction, but it is not sensitive enough to definitively rule out a FB. We propose a stepwise approach using fluoroscopy or possibly flexible bronchoscopy under sedation, in order to reduce the number of negative RBs while restricting the use of the CT scan.

Abstract
Foreign body aspiration is an important cause of emergency hospital admissions in young children less than 3 years of age. It may manifest with acute respiratory difficulty, choking and wheeze acutely or may be asymptomatic. Surgical emphysema is an unusual presentation of bronchial foreign body aspiration in young children. We describe an infant with bronchial foreign body aspiration that manifested with subcutaneous emphysema and pneumomediastinum. Multidetector-row CT with virtual bronchoscopy helped in the diagnosis by detecting and localizing the intraluminal foreign body in the right main bronchus that was removed with rigid bronchoscopy.

Abstract
Advances in multidetector computed tomography (MDCT) technology have given rise to improvements in the noninvasive and comprehensive assessment of the large airways in pediatric patients. Superb two-dimensional and three-dimensional reconstruction MDCT images have revolutionized the display of large airways and enhanced the ability to diagnose large airway diseases in children. The 320-MDCT scanner, which provides combined detailed anatomic and dynamic functional information assessment of the large airways, is promising for the assessment of dynamic large airway disease such as tracheobronchomalacia. This article discusses imaging techniques and clinical applications of MDCT for assessing large airway diseases in pediatric patients.

Abstract
Asphyxiation by an inhaled foreign body is a leading cause of accidental death among children younger than 4 years. We analyzed the recent epidemiology of foreign body aspiration and reviewed the current trends in diagnosis and management. In this article, we discuss anesthetic management of bronchoscopy to remove objects. The reviewed articles total 12,979 pediatric bronchoscopies. Most aspirated foreign bodies are organic materials (81%, confidence interval [CI] = 77%-86%), nuts and seeds being the most common. The majority of foreign bodies (88%, CI = 85%-91%) lodge in the bronchial tree, with the remainder catching in the larynx or trachea. The incidence of right-sided foreign bodies (52%, CI = 48%-55%) is higher than that of left-sided foreign bodies (33%, CI = 30%-37%). A small number of objects fragment and lodge in different parts of the airways. Only 11% (CI = 8%-16%) of the foreign bodies were radio-opaque on radiograph, with chest radiographs being normal in 17% of children (CI = 13%-22%). Although rigid bronchoscopy is the traditional diagnostic "gold standard," the use of computerized tomography, virtual bronchoscopy, and flexible bronchoscopy is increasing. Reported mortality during bronchoscopy is 0.42%. Although asphyxia at presentation or initial emergency bronchoscopy causes some deaths, hypoxic cardiac arrest during retrieval of the object, bronchial rupture, and unspecified intraoperative complications in previously stable patients constitute the majority of in-hospital fatalities. Major complications include severe laryngeal edema or bronchospasm requiring tracheotomy or reintubation, pneumothorax, pneumomediastinum, cardiac arrest, tracheal or bronchial laceration, and hypoxic brain damage (0.96%). Aspiration of gastric contents is not reported. Preoperative assessment should determine where the aspirated foreign body has lodged, what was aspirated, and when the aspiration occurred ("what, where, when"). The choices of inhaled or IV induction, spontaneous or controlled ventilation, and inhaled or IV maintenance may be individualized to the circumstances. Although several anesthetic techniques are effective for managing children with foreign body aspiration, there is no consensus from the literature as to which technique is optimal. An induction that maintains spontaneous ventilation is commonly practiced to minimize the risk of converting a partial proximal obstruction to a complete obstruction. Controlled ventilation combined with IV drugs and paralysis allows for suitable rigid bronchoscopy conditions and a consistent level of anesthesia. Close communication between the anesthesiologist, bronchoscopist, and assistants is essential.

Abstract
PURPOSE The aim of this study was to evaluate the potential use of multidetector CT (MDCT) and virtual bronchoscopy (VB) in the evaluation of tracheobronchial patency in children with suspected bronchial obstruction and to compare its findings with fibreoptic/rigid bronchoscopy or surgery. PATIENTS AND METHODS A total of 43 children (15 girls, 28 boys) with clinically suspected bronchial obstruction underwent contrast enhanced MDCT, using an age- and weight- adjusted low dose protocol. Post-processing was performed and VB and multiplanar reformations (MPR) were obtained at the same sitting. Findings obtained at MDCT and VB were compared with fibreoptic/rigid bronchoscopy and surgery. RESULTS Obstructive pathology was found in 26 children, which included endoluminal foreign body, mucus plugs in 13 children, endobronchial tumour in three children and extrinsic compression (lymph node, aberrant Vessels, mediastinal cysts/tumours) of the tracheobronchial tree in 10 children. In 17 children, no obstructive lesion was identified. Excellent positive correlation was obtained, between MDCT-VB and bronchoscopy/surgery, however, in one child with endobronchial obstruction caused by tracheitis, low dose MDCT-VB was normal, but bronchoscopy revealed granularity and plaques. CONCLUSION MDCT-Virtual bronchoscopy is useful in evaluating bronchial stenosis and obstruction caused by both endoluminal pathology and external compression and has the advantage of looking beyond stenosis. Its main application lies in providing the exact location of suspected foreign body, prior to bronchoscopy. However, it fails to disclose exact nature of obstructing pathology.

Abstract
OBJECTIVE Virtual bronchoscopy is a noninvasive technique which provides an intraluminal view of the tracheobronchial tree. This study aimed to evaluate this technique in comparison with rigid bronchoscopy, in paediatric patients with tracheobronchial foreign bodies undetected by plain chest radiography. METHODS Plain chest radiography was initially performed in 40 children with suspected foreign body aspiration. Computed tomography virtual bronchoscopy was performed in the 20 in whom chest radiography appeared normal. Virtual bronchoscopic images were obtained. All patients underwent rigid bronchoscopy performed by an otolaryngologist blinded to the computed tomography virtual bronchoscopy findings, within 24 hours. Virtual bronchoscopic findings were then compared with the results of rigid bronchoscopy. RESULTS In 12 patients, foreign bodies detected by virtual bronchoscopy were confirmed by rigid bronchoscopy. In one case, a mucous plug was perceived as a foreign body on virtual bronchoscopy. In another case, a minute foreign body was missed on virtual bronchoscopy. The following parameters were calculated: sensitivity, 92.3 per cent; specificity, 85.7 per cent; validity, 90 per cent; positive likelihood ratio, 6.45; and negative likelihood ratio, 0.089. CONCLUSION In the presence of a positive clinical diagnosis and negative chest radiography, computed tomography virtual bronchoscopy must be considered in all cases of tracheobronchial foreign body aspiration, in order to avoid needless rigid bronchoscopy. Computed tomography virtual bronchoscopy is particularly useful in screening cases of occult foreign body aspiration, as it has high sensitivity, specificity and validity.

Abstract
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.
