Abstract
BACKGROUND Oesophageal atresia (OA) is often accompanied by tracheomalacia (TM). The aim of this study was to evaluate its presence in OA patients during routine rigid tracheobronchoscopy (TBS) before primary correction and compare this to postoperative TBS and clinical signs of TM. METHODS This retrospective cohort study included patients born with OA between June 2013 and December 2022 who had received a TBS before OA correction and had been followed for at least twelve months. Definite TM was postoperatively diagnosed through TBS, and probable TM was defined as having symptoms of TM. RESULTS We analysed data from 79 patients, of whom 87% with OA type C. Preoperatively, TM was observed in 33 patients (42% of all patients), seven of whom had severe TM. Definite TM was observed in 21 patients (27%), of whom 15 had severe TM. Forty-one patients (52% of all patients) had developed symptoms of TM within twelve months, including harsh barking cough (n = 15), stridor and/or wheezing (n = 20), recurrent respiratory insufficiency (n = 11), or needing airway surgery (n = 7). The sensitivity of preoperative TBS for the presence of postoperative (definite and probable combined) TM is 50.0%, 95% CI [35.2-64.8], and the specificity 67.6%, 95% CI [51.7-81.1]. Clinical characteristics did not differ between the patients with or without postoperative TM. CONCLUSIONS More than half of the studied patients with OA experienced symptoms of TM. While preoperative TBS is routinely performed prior to surgical OA correction, its predictive value for the presence of postoperative TM remains limited. LEVEL OF EVIDENCE Level II. TYPE OF STUDY Study of Diagnostics Test.

Abstract
INTRODUCTION Tracheomalacia (TM) is an important cause of respiratory morbidity. Dynamic flexible bronchoscopy is considered the gold standard for diagnosis. Dynamic airway computed tomography (DACT) is a low radiation, noninvasive diagnostic tool utilizing images obtained continuously over several respiratory cycles. We aimed to assess the accuracy of DACT in TM diagnosis. METHODS Retrospective analysis of all patients who underwent both DACT and flexible bronchoscopy within 6 months. Airway anterior-posterior (AP) diameter was measured on multiplanar reconstructions CT in both the inspiratory and expiratory phases. Using still images from the bronchoscopy videos, the AP diameter of the trachea was measured at points of maximal and minimal diameter during tidal breathing. Degree of TM on both DACT and flexible bronchoscopy were graded using a scaling system of 50%-74%, 75%-89%, and 90%-100% as described by the European Respiratory Society. RESULTS Twenty-four patients met inclusion criteria with an average time of 19.5 days between CT and bronchoscopy. The specificity and sensitivity of DACT for the overall diagnosis of TM was 100% and 68%, respectively, with a positive predictive value of 100% and a negative predictive value of 62%. There was a strong positive correlation between DACT and flexible bronchoscopy in the measurement of tracheal AP diameter changes (ρ = 0.773, R2 0.597, p = 0.00001). Mean effective radiation dose for DACT was 0.1 mSv. CONCLUSION Ultralow dose DACT has excellent specificity and positive predictive value for both detection of TM and categorizing severity of tracheal collapse but is not sufficiently sensitive to rule it out.

Abstract
OBJECTIVES Spirometry is easily accessible yet there is limited data in children with tracheomalacia. Availability of such data may inform clinical practice. We aimed to describe spirometry indices of children with tracheomalacia, including Empey index and flow-volume curve pattern, and determine whether these indices relate with bronchoscopic features. METHODS From the database of children with tracheomalacia diagnosed during 2016-2019, we reviewed their flexible bronchoscopy and spirometry data in a blinded manner. We specially evaluated several spirometry indices and tracheomalacia features (cross-sectional lumen reduction, malacic length, and presence of bronchomalacia) and determined their association using multivariable regression. RESULTS Of 53 children with tracheomalacia, the mean (SD) peak expiratory flow (PEF) was below the normal range [68.9 percent of predicted value (23.08)]. However, all other spirometry parameters were within normal range [Z-score forced expired volume in 1 s (FEV1 ) = -1.18 (1.39), forced vital capacity (FVC) = -0.61 (1.46), forced expiratory flow between 25% and 75% of vital capacity (FEF25%-75% ) = -1.43 (1.10), FEV1 /FVC = -1.04 (1.08)], Empey Index = 8.21 (1.59). The most common flow-volume curve pattern was the "knee" pattern (n = 39, 73.6%). Multivariable linear regression identified the presence of bronchomalacia was significantly associated with lower flows: FEV1 [coefficient (95% CI) -0.78 (-1.54, -0.02)], FEF25%-75% [-0.61 (-1.22, 0)], and PEF [-12.69 (-21.13, -4.25)], all p ≤ 0.05. Other bronchoscopic-defined tracheomalacia features examined (cross-sectional lumen reduction, malacic length) were not significantly associated with spirometry indices. CONCLUSION The "knee" pattern in spirometry flow-volume curve is common in children with tracheomalacia but other indices, including Empey index, cannot be used to characterize tracheomalacia. Spirometry indices were not significantly associated with bronchoscopic tracheomalacia features but children with tracheobronchomalacia have significantly lower flow than those with tracheomalacia alone.

Abstract
INTRODUCTION Tracheomalacia is a common congenital condition causing stridor in young children. However, the evaluation of these children remains poorly standardised across institutions. METHODS We conducted a retrospective review of all children undergoing an elective laryngotracheobronchoscopy at a single tertiary paediatric institution between March 2010 and December 2018. Emergency bronchoscopies and children with tracheostomies were excluded. 1163 children undergoing an elective bronchoscopy were included in this study, and 545 children also had an airway fluoroscopy. RESULTS The median age at bronchoscopy was 17 months, and the majority of children were male. Tracheomalacia was diagnosed in 21.6% of children at bronchoscopy, of these 48.5% had tracheomalacia diagnosed on a previous airway fluoroscopy. Overall, airway fluoroscopy had a low sensitivity (62.3%) and a low specificity (67.5%) for diagnosis of tracheomalacia when compared with bronchoscopy. Increasing severity of tracheomalacia on airway screen significantly predicted a diagnosis of tracheomalacia on bronchoscopy. CONCLUSIONS Airway fluoroscopy has a low sensitivity and specificity in diagnosis of tracheomalacia and should be used judiciously rather than as a screening tool for children with stridor. However, this imaging technique may be beneficial in investigating children with severe symptoms who have had other conditions such as laryngomalacia excluded.

Abstract
OBJECTIVE Children with tracheomalacia can develop chronic lower airway infection and neutrophilic inflammation. It is plausible children with tracheomalacia are at increased risk of developing bronchiectasis. We hypothesised that compared with controls, tracheomalacia in children is associated with bronchiectasis. DESIGN Single-centre, case-control study. SETTING AND PATIENTS 45 children with chest high-resolution CT (c-HRCT) confirmed bronchiectasis (cases) and enrolled in the Australian Bronchiectasis Registry were selected randomly from Queensland, and 90 unmatched children without chronic respiratory symptoms or radiographic evidence of bronchiectasis (disease controls). Cases and controls had flexible bronchoscopy performed for clinical reasons within 4 weeks of their c-HRCT. INTERVENTIONS The bronchoscopy videos were reviewed in a blinded manner for: (a) any tracheomalacia (any shape deformity of the trachea at end-expiration) and (b) tracheomalacia defined by the European Respiratory Society (ERS) statement (>50% expiratory reduction in the cross-sectional luminal area). MAIN OUTCOME MEASURES AND RESULTS Cases were younger (median age=2.6 years, IQR 1.5-4.1) than controls (7.8 years, IQR 3.4-12.8), but well-balanced for sex (56% and 52% male, respectively). Using multivariable analysis (adjusted for age), the presence of any tracheomalacia was significantly associated with bronchiectasis (adjusted OR (ORadj)=13.2, 95% CI 3.2 to 55), while that for ERS-defined tracheomalacia further increased this risk (ORadj=24.4, 95% CI 3.4 to infinity). CONCLUSION Bronchoscopic-defined tracheomalacia is associated with childhood bronchiectasis. While causality cannot be inferred, children with tracheomalacia should be monitored for chronic (>4 weeks) wet cough, the most common symptom of bronchiectasis, which if present should be treated and then investigated if the cough persists or is recurrent.

Abstract
BACKGROUND Interventional pediatric flexible bronchoscopy has many advantages over radiologic investigations in diagnosing uncommon congenital H-type tracheoesophageal fistula (TEF), dual TEF, bronchoesophageal fistula (BEF) and fistula recurrence including higher rates of identification and anatomic localization with guide wire cannulation. We compare the diagnostic utility of flexible bronchoscopy to radiologic techniques for congenital aerodigestive fistula. METHODS A single center retrospective review was completed of all cases of pediatric TEF and BEF diagnosed with flexible bronchoscopy between January 2000 and November 2020. RESULTS Fistulae were diagnosed 21 times in 18 patients at a median age of 1.22 years (interquartile range: 0.50 to 2.99). The median time from diagnosis to repair was 17.5 days (interquartile range: 5.5 to 43). Symptoms commonly related to fistula were found in all patients. Uncommon fistulae included single H-type TEF (n=10, 47.6%), dual H-type TEF (n=2, 9.5%), dual proximal and distal TEF with esophageal atresia (n=5, 23.8%), TEF recurrence (n=2, 14.3%), BEF (n=1, 4.8%), and a BEF recurrence (n=1, 4.8%). Flexible bronchoscopy confirmed the diagnosis in all fistulae using a guide wire cannulation or methylene blue dye injection. A combined procedure with simultaneous bronchoscopy and esophagoscopy was used for 6 fistulae. The positive examination rate was 75% for bronchoscopy compared with 2.6% for contrast swallow studies and 28.6% for tube esophagograms. CONCLUSIONS Flexible bronchoscopy should be considered as a first line investigation in uncommon aerodigestive fistulae. In the absence of a skilled bronchoscopist, the best radiologic investigation is a pull-back tube esophagogram but may still require endoscopic confirmation at the time of fistula repair.

Abstract
Tracheoesophageal fistula (TEF) with esophageal atresia (EA) is a common congenital anomaly that is associated with significant respiratory morbidity throughout life. The objective of this document is to provide a framework for the diagnosis and management of the respiratory complications that are associated with the condition. As there are no randomized controlled studies on the subject, a group of experts used a modification of the Rand Appropriateness Method to describe the various aspects of the condition in terms of their relative importance, and to rate the available diagnostic methods and therapeutic interventions on the basis of their appropriateness and necessity. Specific recommendations were formulated and reported as Level A, B, and C based on whether they were based on "strong", "moderate" or "weak" agreement. The tracheomalacia that exists in the site of the fistula was considered the main abnormality that predisposes to all other respiratory complications due to airway collapse and impaired clearance of secretions. Aspiration due to impaired airway protection reflexes is the main underlying contributing mechanism. Flexible bronchoscopy is the main diagnostic modality, aided by imaging modalities, especially CT scans of the chest. Noninvasive positive airway pressure support, surgical techniques such as tracheopexy and rarely tracheostomy are required for the management of severe tracheomalacia. Regular long-term follow-up by a multidisciplinary team was considered imperative. Specific templates outlining the elements of the clinical respiratory evaluation according to the patients' age were also developed.

Abstract
OBJECTIVES/HYPOTHESIS Both flexible and rigid bronchoscopy can be used to assess tracheomalacia; however, there is limited evidence comparing the two techniques. The objective of this study was to compare flexible and rigid bronchoscopy for evaluating the location and severity of tracheomalacia in children. STUDY DESIGN Retrospective case series. METHODS This was a retrospective study of children with both flexible and rigid bronchoscopy under the same sedation. All bronchoscopies were reviewed by three bronchoscopists for the location and severity of tracheomalacia. The location of collapse was defined as upper, middle, or lower trachea, and the severity of collapse was defined as none (0%-25% collapse), mild/moderate (26%-75% collapse), and severe (>75% collapse). RESULTS Twenty-one patients were recruited for this study with a variety of neonatal respiratory diseases. There was 94% agreement (κ = 0.64) for assessment of tracheomalacia in the upper trachea. However, agreement was only 75% (κ = 0.50) in the middle trachea and 76% (κ = 0.52) in the lower trachea. In the subset of patients without tracheostomy, agreement improved to 100%, 88%, and 82% for the upper, middle, and lower trachea, respectively. There was poor correlation for tracheomalacia severity in the middle trachea (ρ = 0.30, P = .2) and moderate in the lower trachea (ρ = 0.63, P = .002). CONCLUSIONS Although there is moderate agreement between flexible and rigid bronchoscopy for evaluating the presence of tracheomalacia, there can be differences in the two techniques, particularly when assessing severity of airway collapse. Future studies will be needed to understand factors that result in the discordance of flexible and rigid bronchoscopy for assessing airway dynamics.

Abstract
Tracheomalacia and tracheobronchomalacia may be primary abnormalities of the large airways or associated with a wide variety of congenital and acquired conditions. The evidence on diagnosis, classification and management is scant. There is no universally accepted classification of severity. Clinical presentation includes early-onset stridor or fixed wheeze, recurrent infections, brassy cough and even near-death attacks, depending on the site and severity of the lesion. Diagnosis is usually made by flexible bronchoscopy in a free-breathing child but may also be shown by other dynamic imaging techniques such as low-contrast volume bronchography, computed tomography or magnetic resonance imaging. Lung function testing can provide supportive evidence but is not diagnostic. Management may be medical or surgical, depending on the nature and severity of the lesions, but the evidence base for any therapy is limited. While medical options that include bronchodilators, anti-muscarinic agents, mucolytics and antibiotics (as well as treatment of comorbidities and associated conditions) are used, there is currently little evidence for benefit. Chest physiotherapy is commonly prescribed, but the evidence base is poor. When symptoms are severe, surgical options include aortopexy or posterior tracheopexy, tracheal resection of short affected segments, internal stents and external airway splinting. If respiratory support is needed, continuous positive airway pressure is the most commonly used modality either via a face mask or tracheostomy. Parents of children with tracheobronchomalacia report diagnostic delays and anxieties about how to manage their child's condition, and want more information. There is a need for more research to establish an evidence base for malacia. This European Respiratory Society statement provides a review of the current literature to inform future study.

Abstract
AIM Oesophagealatresia/tracheo-oesophageal fistula (OA-TOF) is associated with tracheomalacia (TM). In our institution it is routine for OA-TOF patients to undergo dynamic flexible bronchoscopy (DFB) assessing both the site of the fistula and the presence or absence of TM. We aimed to determine the value of this investigation as a screening tool to predict subsequent symptomatic tracheomalacia in these patients. METHODS All patients with OA-TOF who underwent DFB at the time of initial repair between June 2014 and November 2016 were included prospectively. The findings at DFB were recorded. Patients were grouped according to the presence or absence of TM and followed to determine which of them developed symptomatic airway problems. The sensitivity and specificity of TM at initial bronchoscopy as a screening tool for subsequent symptomatic TM were calculated. The study was given ethical approval by our institution. MAIN RESULTS Twenty-three patients were included in the study. Median follow-up was for 7 (1-27) months. Fifteen (65%) were found to have TM at their first DFB; 13 (57%) subsequently developed airway symptoms, and of these 11 had TM at initial DFB. One patient with severe TM (>90% tracheal collapse) at initial DFB was completely asymptomatic following OA-TOF repair. The sensitivity was 85%, and specificity was 60%. The positive and negative predictive values were 73% and 75%, respectively. CONCLUSIONS DFB is a useful tool in many aspects of the management of OA/TOF. However, it is not a good screening tool to predict symptomatic tracheomalacia with moderate sensitivity and a low specificity. LEVEL OF EVIDENCE Level IIb, Retrospective cohort study.

Abstract
Chronic cough in children is increasingly defined as a cough that lasts more than four weeks. It is recognized as a different entity than cough in adults. As a result, the diagnostic approach and management of chronic cough in children are no longer extrapolated from adult guidelines. These differences are attributed to the various characteristics of the respiratory tract, immunological system and nervous system in children. Specific paediatric guidelines and algorithms for chronic cough are now widely applied. Post-infectious cough, asthma, bronchiectasis, malacia and protracted bacterial bronchitis (PBB) appear to be the major causes of cough in young children. By adolescence, the causes of cough are more likely to be similar to those in adults, namely, gastroesophageal reflux, asthma, and upper airway syndrome. In a primary setting, it is essential to investigate the underlying disease entity that initiates and sustains chronic cough. The use of cough management protocols or algorithms improves clinical outcomes and should differ depending on the associated characteristics of the cough and the child's clinical history. Performing a thorough history and physical examination is crucial to starting an individualised approach. A correct interpretation of the phenotypic presentation can be translated into guidance for workup. This approach will be helpful for adequate management without the risk of inappropriate investigations or inadequate treatment.
