Abstract
INTRODUCTION Posterior tracheopexy (PT) directly addresses the posterior trachealis membrane intrusion in severe tracheomalacia. During PT, the esophagus is mobilized and membranous trachea is sutured to the prevertebral fascia. Although dysphagia has been reported as a possible complication of PT, in the literature there are no data investigating postoperative esophageal anatomy and digestive symptoms. Our aim was to study clinical and radiological consequences of PT on esophagus. METHODS Patients with symptomatic tracheobronchomalacia scheduled for PT between May 2019 and November 2022 underwent pre- and postoperative esophagogram. For each patient, we analyzed radiological images and measured esophageal deviation providing new radiological parameters. RESULTS All 12 patients underwent thoracoscopic PT (n = 3) or robot-assisted thoracoscopic PT (n = 9). For all patients, the postoperative esophagogram showed a right dislocation of the thoracic esophagus (median postoperative deviation = 27.5 mm). We report an esophageal perforation at postoperative day 7 in a patient affected by esophageal atresia, who underwent several surgical procedures before. A stent was placed and esophagus healed. Another patient with severe right dislocation referred transient dysphagia to solids, which resolved gradually in the first postoperative year. All the other patients did not present any esophageal symptoms. CONCLUSION For the first time, we demonstrate the right dislocation of the esophagus after PT and we propose an objective method to measure it. In most patients, PT is a procedure not affecting esophageal function, but dysphagia can occur if dislocation is important. Esophagus mobilization during PT should be cautious, especially in patients who underwent previous thoracic procedures.

Abstract
BACKGROUND Tracheobronchomalacia (TBM) is characterized by excessive dynamic airway collapse. Severe TBM can be associated with substantial morbidity. Children with secondary TBM associated with esophageal atresia/tracheoesophageal fistula (EA/TEF) and vascular-related airway compression (VRAC) demonstrate clinical improvement following airway pexy surgery. It is unclear if children with severe primary TBM, without secondary etiologies (EA/TEF, vascular ring, intrinsic pulmonary pathology, or complex cardiac disease) demonstrate clinical improvement following airway pexy surgery. MATERIALS AND METHODS The study cohort consisted of 73 children with severe primary TBM who underwent airway pexy surgery between 2013 and 2020 at Boston Children's Hospital. Pre- and postoperative symptoms as well as bronchoscopic findings were compared with Fisher exact test for categorical data and Student's t-test for continuous data. RESULTS Statistically significant improvements in clinical symptoms were observed, including cough, noisy breathing, prolonged respiratory infections, pneumonias, exercise intolerance, cyanotic spells, brief resolved unexplained events (BRUE), and noninvasive positive pressure ventilation (NIPPV) dependence. No significant differences were seen regarding oxygen dependence, ventilator dependence, or respiratory distress requiring NIPPV. Comparison of pre- and postoperative dynamic bronchoscopy findings revealed statistically significant improvement in the percent of airway collapse in all anatomic locations except at the level of the upper trachea (usually not malacic). Despite some initial improvements, 21 (29%) patients remained symptomatic and underwent additional airway pexies with improvement in symptoms. CONCLUSION Airway pexy surgery resulted in significant improvement in clinical symptoms and bronchoscopic findings for children with severe primary TBM; however, future prospective and long-term studies are needed to confirm this benefit.

Abstract
OBJECTIVE In children with tracheobronchomalacia, surgical management should be reserved for the most severe cases and be specific to the type and location of tracheobronchomalacia. The goal of this study is to describe the presentation and outcomes of children with severe tracheobronchomalacia undergoing surgery. METHODS Retrospective case series of 20 children operated for severe tracheobronchomalacia at a tertiary hospital from 2003 to 2023. Data were collected on symptoms age at diagnosis, associated comorbidities, previous surgery, age at surgery, operative approach, time of follow-up, and outcome. Surgical success was defined as symptom improvement. RESULTS The most frequent symptoms of severe tracheobronchomalacia were stridor (50 %), cyanosis (50 %), and recurrent respiratory infections (45 %). All patients had one or more underlying conditions, most commonly esophageal atresia (40 %) and prematurity (35 %). Bronchoscopy were performed in all patients. Based on etiology, patients underwent the following procedures: anterior aortopexy (n = 15/75 %), posterior tracheopexy (n = 4/20 %), and/or posterior descending aortopexy (n = 4/20 %). Three patients underwent anterior aortopexy and posterior tracheopexy procedures. After a median follow-up of 12 months, 16 patients (80 %) had improvement in respiratory symptoms. Decannulation was achieved in three (37.5 %) out of eight patients with previous tracheotomy. The presence of dying spells at diagnosis was associated with surgical failure. CONCLUSIONS Isolated or combined surgical procedures improved respiratory symptoms in 80 % of children with severe tracheobronchomalacia. The choice of procedure should be individualized and guided by etiology: anterior aortopexy for anterior compression, posterior tracheopexy for membranous intrusion, and posterior descending aortopexy for left bronchus obstruction.

Abstract
Despite improving the survival after repair of esophageal atresia (EA), the morbidity of EA repair remains high. Specifically, tracheomalacia (TM) is one of the most frequent complications of EA repair. Continuous positive airway pressure is generally applied for the treatment of TM. However, surgical intervention is required against an apparent life-threatening event or inability to perform extubation for a long period. According to our review, most cases of TM showed symptom improvement after aortopexy. The ratio of the trachea's lateral and anterior-posterior diameter at the brachiocephalic artery crossing the trachea, which reflects the compression of the trachea by the brachiocephalic artery, is a good indicator of aortopexy. Our finding suggests that most TM cases associated with EA may not be caused by tracheal fragility alone, but may involve blood vessel compression. Posterior tracheopexy (PT) is also an effective treatment for TM. Recently, open or thoracoscopic PT was able to be performed simultaneously with EA repair. In many cases, aortopexy or PT is a safe and effective surgical treatment for TM with EA. Other surgical procedures, such as external stenting, should be considered for patients with diffuse-type TM for whom aortopexy and PT appear relatively ineffective.

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
OBJECTIVE Posterior tracheomalacia (TM) is characterized by excessive intraluminal displacement of the tracheal membranous wall. Recently, novel surgical strategies for repair of posterior TM have been introduced. To our knowledge, these strategies have not been evaluated in a model of posterior TM. Thus, we sought to design an ex vivo mechanical model of posterior TM to evaluate potential repair interventions. METHODS A model for posterior TM was created with partial thickness longitudinal incisions to the posterior aspect of ex vivo porcine trachea. Three groups of tracheas were tested: (1) control (unmanipulated), (2) posterior TM (injury), and (3) intervention (repair). Interventions included external splinting with 0.3 and 0.5 mm bioresorbable plates, posterior tracheopexy, and injection tracheoplasty with calcium hydroxylapatite. An airtight tracheal system was created to measure tracheal wall collapse with changes in negative pressure. A bronchoscope and pressure transducer were connected to either end. Cross-sectional area of the tracheal lumen was analyzed using ImageJ software (National Institutes of Health, Bethesda, MD). RESULTS Average percent reduction in cross-sectional area of the tracheal lumen was compared using a two-tailed paired t-test. Significant differences were found between control and TM groups (p < 0.019). There was no significant difference between control and external splinting and posterior tracheopexy groups (p > 0.14). CONCLUSION We describe an ex vivo model for posterior TM that replicates airway collapse. External splinting and tracheopexy interventions showed recovery of the injured tracheal segment. Injection tracheoplasty did not improve the TM. LEVEL OF EVIDENCE N/A Laryngoscope, 133:2000-2006, 2023.

Abstract
Tracheomalacia (TM) is a condition characterized by a weak tracheal cartilage and/or muscle, resulting in excessive collapse of the airway in the newborns. Current treatments including tracheal reconstruction, tracheoplasty, endo- and extra-luminal stents have limitations. To address these limitations, this work proposes a new strategy by wrapping an adhesive hydrogel patch around a malacic trachea. Through a numerical model, first it was demonstrated that a hydrogel patch with sufficient mechanical and adhesion strength can preserve the trachea's physiological shape. Accordingly, a new hydrogel providing robust adhesion on wet tracheal surfaces was synthesized employing the hydroxyethyl acrylamide (HEAam) and polyethylene glycol methacrylate (PEGDMA) as main polymer network and crosslinker, respectively. Ex vivo experiments revealed that the adhesive hydrogel patches can restrain the collapsing of malacic trachea under negative pressure. This study may open the possibility of using an adhesive hydrogel as a new approach in the difficult clinical situation of tracheomalacia.

Abstract
BACKGROUND H-type Tracheoesophageal Fistula (TEF) is a particular type of congenital esophageal anomalies, in which patients present with non-specific symptoms that can result in delayed diagnosis. Here, we report two pediatric cases with a rarer variant called ‟dual H-type TEFˮ. CASE PRESENTATION We present two cases of H-type TEF. The first was a 45-day-old boy with feeding problem and cyanosis while feeding, and the second was a three-month-old girl with cough and choking after feeding from the first day of birth. In both cases, two separate TEFs were detected during diagnostic evaluation by flexible bronchoscopy. Both were repaired simultaneously through a cervical incision. The first patient deteriorated 13 days after the surgery, disturbancing in acid-base balance and expired unfortunately. CONCLUSION Hence, it is necessary to consider the possibility of double TEF in any newly diagnosed H-type TEF.

Abstract
Background This study aimed to evaluate the effectiveness of primary posterior tracheopexy (PPT) in reducing ventilator dependence after repair of esophageal atresia (EA), and the risk of respiratory tract infections (RTI) requiring readmissions within one year. Methods This retrospective cohort study recruited patients with EA admitted to our hospital between June 2020 and December 2021. Results In the PPT group (n = 17), the time to extubation after surgery was 86.7 h for 12 patients, with one patient (8.3%) requiring repeated postoperation intubation; six-in-sixteen patients (37.5%) experience at least one RTI requiring hospitalization in one year. In the non-PPT group (n = 17), the time to extubation was 127.0 h for 14 patients, with six-in-fourteen patients (42.9%) requiring repeated intubation; twelve-in-seventeen patients (70.6%) experienced at least one RTI requiring hospitalization in one year. Conclusions Although the differences did not reach statistical significance due to limited number of participants, patients underwent PPT during EA repair had lower chance of repeated intubation and decreased risk of RTI requiring admissions within one year.

Dynamic Volumetric Computed Tomography Angiography is an Effective Method to Evaluate Tracheomalacia in Children. Laryngoscope 2023; 133:410-416.

Abstract
OBJECTIVE Standard methods to evaluate tracheal pathology in children, including bronchoscopy, may require general anesthesia. Conventional dynamic proximal airway imaging in noncooperative children requires endotracheal intubation and/or medically induced apnea, which may affect airway mechanics and diagnostic performance. We describe a technique for unsedated dynamic volumetric computed tomography angiography (DV-CTA) of the proximal airway and surrounding vasculature in children and evaluate its performance compared to the reference-standard of rigid bronchoscopy. METHODS Children who had undergone DV-CTA and bronchoscopy in one-year were retrospectively identified. Imaging studies were reviewed by an expert reader blinded to the bronchoscopy findings of primary or secondary tracheomalacia. Airway narrowing, if present, was characterized as static and/or dynamic, with tracheomalacia defined as >50% collapse of the tracheal cross-sectional area in exhalation. Pearson correlation was used for comparison. RESULTS Over a 19-month period, we identified 32 children (median age 8 months, range 3-14 months) who had undergone DV-CTA and bronchoscopy within a 90-day period of each other. All studies were unsedated and free-breathing. The primary reasons for evaluation included noisy breathing, stridor, and screening for tracheomalacia. There was excellent agreement between DV-CTA and bronchoscopy for diagnosis of tracheomalacia (κ = 0.81, p < 0.001), which improved if children (n = 25) had the studies within 30 days of each other (κ = 0.91, p < 0.001). CTA provided incremental information on severity, and cause of secondary tracheomalacia. CONCLUSION For most children, DV-CTA requires no sedation or respiratory manipulation and correlates strongly with bronchoscopy for the diagnosis of tracheomalacia.

Abstract
Circumflex aortic arch is a rare vascular ring anomaly, which is often associated with tracheobronchomalacia. Aortic uncrossing is the definitive repair of this condition, which is a major high-risk operation; therefore, it is not suitable for small patients such as newborn infants or individuals who have severe comorbidities. We present a case of the circumflex aortic arch with tracheobronchomalacia in a 2.7-kg infant who underwent successful innovative combined surgery of the airway and the aorta.

Abstract
Anomalies in tracheo-esophageal development result in a spectrum of congenital malformations ranging from, most commonly, esophageal atresia with or without trachea-esophageal fistula (EA+/-TEF) to esophageal web, duplication, stricture, tracheomalacia and tracheal agenesis. Despite the relative frequency of EA, however, the underlying etiology remains unknown and is likely due to a combination of genetic, epigenetic and environmental factors. In recent years, animal models have dramatically increased our understanding of the molecular and morphological processes involved in normal esophageal development during the key stages of anterior-posterior regionalization, dorsal-ventral patterning and morphogenic separation. Moreover, the use of animal models in conjunction with increasingly advanced techniques such as genomic sequencing, sophisticated live imaging studies and organoid models have more recently cast light on potential mechanisms involved in EA pathogenesis. This article aims to unravel some of the mysteries behind the anatomy and embryology of EA whilst providing insights into future directions for research.

Abstract
Esophageal atresia with or without tracheoesophageal fistula and tracheobronchomalacia encompass 2 of the most common complex congenital intrathoracic anomalies. Tailoring interventions to address the constellation of problems present in each patient is essential. Due to advances in neonatology, anesthesia, pulmonary, gastroenterology, nutrition and surgery care for patients with complex congenital tracheoesophageal disorders has improved dramatically. Treatment strategies tailored to the individual patient needs are best implimented under the aegis of a comprehensive longitudinal multidisciplinary care team.

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
OBJECTIVES To describe growth and feeding outcomes in patients with type C esophageal atresia who underwent early primary repair and to identify predictors for poor growth. STUDY DESIGN This single-center, retrospective, cohort study included all patients with type C esophageal atresia who underwent early primary repair from 2013 to 2019. Weight-for-age z score (WAZ) was calculated at birth, and every 6 months until 3 years postoperatively. Longitudinal median regression was used to evaluate WAZ over time. A multivariable logistic regression model explored predictors of growth outcomes. RESULTS Of 46 infants who met the inclusion criteria, 72% were term. The median age at repair was 1.5 days of life (IQR, 1-2 days of life) and the hospital length of stay was 20 days (IQR-14, 30 days). Two patients had esophageal leak (4.3%). The median WAZ at birth was below average (-0.72; IQR, -1.37 to -0.40), but improved to reach average by 3 years (-0.025; IQR, -0.85 to 0.97, P < .001). At discharge, 72% of patients were receiving full oral nutrition, which improved to 95% by 3 years. The only independent predictor of poor growth at 1 year (WAZ < -1 [33%]) was WAZ at discharge (P = .02). CONCLUSIONS Infants with esophageal atresia who undergo early primary repair are capable of achieving standard growth curves by 3 years of age. However, poor discharge WAZ score was predictive of poor WAZ score at 1 year. Efforts to identify at-risk patients and institute targeted inpatient and outpatient nutrition interventions are needed to improve their growth trajectory.

Abstract
Bronchoscopy-guided diagnostic and interventional airway procedures are gaining in popularity and prominence in pediatric surgery. Many of these procedures have been used successfully in the adult population but have not been used in children due to a lack of appropriately sized instruments. Recent technological advances have led to the creation of instruments to enable many more diagnostic and therapeutic procedures to be done under bronchoscopic guidance. These procedures vary significantly in their length and invasiveness and require vastly different anesthetic plans that must be easily adapted to situational and procedural changes. In addition to close communication between the anesthesiology and procedural teams; an understanding of the type of procedure, anesthetic requirements, and potential patient risks is paramount to a successful anesthetic. This review will focus on new rigid bronchoscopic procedures, goals for their respective anesthetic management, and unique tips and trick for how to maintain adequate oxygenation and ventilation in each scenario.

Abstract
OBJECTIVE Although most children do well after operations to relieve vascular compression of the esophagus and airway, many will have persistent/recurrent symptoms. We review our surgical experience using a customized approach to correct various etiologies of failure after vascular ring/decompression surgery. METHODS Our institutional database identified children who underwent reoperation for persistent/recurrent symptoms after vascular ring or aberrant arterial decompression surgery between January 2014 and December 2019. Charts were reviewed for operative approaches and clinical data. Findings were analyzed by Fisher exact test for comparison between groups. RESULTS Twenty-seven children required reoperative surgery. Detailed preoperative workup identified 5 etiologies of failure for a customized approach. Residual scarring was corrected by lysis and rotational esophagoplasty (n = 23/27); fibrotic bands re-creating a ring were divided (n = 11); ongoing vascular compression was addressed by descending aortopexy (n = 19), aberrant subclavian division (n = 7), aortic uncrossing procedure (n = 4), and Kommerell resection (n = 8); anterior aortopexy (n = 6) and anterior tracheopexy (n = 9) corrected cartilage malformation; and tracheobronchomalacia was addressed with posterior airway pexy (n = 26). At available short-term follow-up (median 1 year), 21 of 22 patients (95%) had symptom improvement, and on bronchoscopy, the average number of airway sections with severe tracheobronchomalacia decreased from 2.8 ± 1.7 to 0.5 ± 0.9 (P < .001). CONCLUSIONS Persistent/recurrent symptoms after release of vascular compression are frequently caused by 5 different etiologies. A multidisciplinary strategy for workup and a customized operative approach can effectively treat these cases and may suggest opportunity at the index surgery to prevent reoperation and achieve optimal outcomes.

Abstract
BACKGROUND Tracheobronchomalacia (TBM) contributes to the increased morbidity and mortality observed in preterm infants. Effective strategies for the prevention of TBM are necessary to achieve better outcomes. We sought to identify risk factors associated with the development of TBM in preterm infants. Optimal cut-off values for each risk factor were also determined. METHODS A total of 80 infants who were born at 36 week's gestation or earlier and underwent flexible bronchoscopy were included in our study sample. A comparison of demographic and clinical risk factors between those with TBM (n = 35, 44%) and those without TBM (n = 45, 56%) was conducted using multivariate logistic regression analysis. Receiver operating characteristic curve analysis was performed to determine the appropriate cut-off values for predicting the development of TBM. RESULTS In the multivariate analysis, only peak inspiratory pressure (PIP) and the number of intubation days remained significantly different between infants with and without TBM. Preterm infants with TBM received higher PIP (odds ratio: [OR], 1.067; 95% confidence interval [CI], 1.010-1.128; p = .020) and were intubated for longer (odds ratio [OR], 1.019; 95% CI, 1.003-1.035; p = .016) than those without TBM. Infants who received PIP > 19.5 cmH2 O or were intubated for >79.5 days were associated with a significantly higher risk of presence of TBM. CONCLUSION High PIP and prolonged intubation were major risk factors for the development of TBM in premature infants. Those who require PIP > 19.5 cmH2 O or intubation >79.5 days warrant bronchoscopy examination for early diagnosis and management of TBM.

Abstract
Tracheobronchomalacia (TBM) is the most common tracheobronchial obstruction. Most cases are mild to moderate; therefore, they do not need surgical treatment. Severe tracheomalacia, however, represents a diagnostic and therapeutic challenge since they are very heterogeneous. In the armamentarium of resources for the treatment of dynamic airway collapse, splints and stents are two underused strategies and yet, they may represent the best alternative in selected cases. Lately, computed tomography 3D reconstruction of the airway has been used for the design of virtual models that can be 3D-printed for the creation of novel devices to address training, simulation, and biotechnological implants for refractory and severe airway malformations. This manuscript examines the role of resorbable stents, splints, and the 3D reconstruction and printing of the pediatric airway in tracheobronchomalacia.

Abstract
Airway collapse from dynamic tracheobronchomalacia (TBM), static compression from vascular compression, and/or tracheobronchial deformation are challenging conditions. Patients are best assessed and managed by a multidisciplinary team in centers specializing in complex pediatric airway disorders. Suspicion is made through clinical history and physical examination, diagnosis of location and severity by dynamic 3-phase bronchoscopy, and surgical treatment planning by MDCT and other studies as necessary to completely understand the problems. The treatment plan should be patient-based with a thorough approach to the underlying pathology, clinical concerns, and combined abnormalities. Patients should undergo maximum medical therapy prior to committing to other interventions. For those children considered candidates for surgical intervention, all other associated conditions, including vascular anomalies, chest wall deformities, mediastinal lesions, or other airway pathologies, should also be considered. Our preference is to correct the airway lesions at the same operation as other comorbidities, if possible, to prevent multiple reoperations with their attendant increased risks. We also strongly advocate for the use of recurrent laryngeal nerve monitoring in all cases of cervical or thoracic surgery to minimize the risks to vocal cord function and laryngeal sensation. Studies that evaluate the effect of these interventions on the patient and caregiver's quality of life are needed to fully grasp the impact of TBM on this challenging patient population.

Abstract
OBJECTIVES Tracheobronchomalacia (TBM) is characterized by collapse of trachea, bronchi or both, leading to dyspnoea, expiratory stridor, coughing or recurrent airway infections. Surgical treatment with aortopexy is warranted for severe TBM. We describe a modified aortopexy technique with aortic wall strap sutures that evenly distributes the traction force over the full width of the aortic arch. The aim of this study was to determine the outcomes of this modified anterior aortopexy technique. METHODS Retrospective chart review of all patients undergoing aortopexy with aortic wall strap sutures for TBM between January 2010 and June 2020 in 2 tertiary hospitals in the Netherlands. RESULTS Twenty-four patients [median age 9 months (interquartile range 2-117 months); 71% male] underwent aortopexy with the modified technique for TBM (52%), tracheomalacia (40%) or bonchomalacia (8%). Aortopexy was successful in 91.7%, defined as relief or decrease of respiratory symptoms and no need for respiratory support. Complications occurred in 8.3% and mortality was 4%. CONCLUSIONS Aortopexy with non-absorbable strap sutures seems an effective and safe treatment for severe TBM. This study supports the hypothesis that strap sutures provide a solid and reliable traction force, but future comparative studies should confirm the benefit of strap sutures over conventional techniques.

Abstract
Objective To report our experience with novel external tracheal and bronchial placed bioresorbable splints in children with severe symptomatic airway collapse. Methods Retrospective review of patients undergoing bioresorbable splint placement. Results Between July 2018 and February 2020, 14 patients received 16 external splints (trachea, n = 8; left bronchus, n = 7; and right bronchus, n = 1). Preoperatively, 7 patients had a tracheostomy; 6 of them were receiving mechanical ventilation with ventilator settings so high that they required an inpatient setting, often in an intensive care unit. Median age at implant was 14.5 months (range, 2 months-14 years). Splints were formed from moldable bioresorbable plates (RapidSorb; Synthes, Oberdorf, Switzerland) and were customized intraoperatively around a Hegar dilator. A series of Prolene sutures were placed through into the airway cartilage under simultaneous bronchoscopic and direct visualization and then tied securing the airway within the splint. Concomitant procedures were also performed in the region of the airway splints, consisting of airway reconstruction, cardiovascular procedures, and/or esophageal rotation (related to posterior tracheopexy). Median follow-up was 20 months (interquartile range, 12-21 months). Four patients required no further intervention. Although not necessarily in the splinted region, 7 patients required additional procedures, including posterior tracheobronchopexy (n = 2), temporary tracheal stent placement (n = 1), tracheal resection with end-to-end anastomosis (n = 1), closure tracheostomy (n = 1), and tracheostomy placement (n = 2). One patient required splint replacement and in 1 patient, the splint was removed later. All patients (except 2 deaths from unrelated causes) were discharged home. Three patients required mechanical ventilation at lower settings that allowed home ventilation (1 of those only at night), and 4 patients required tracheostomy collar. Indications for tracheostomy included subglottic stenosis, vocal cord paralysis, pulmonary insufficiency, small airway malacia, and laryngomalacia. Conclusions An external bioresorbable splint can provide temporary external support while allowing the age-proportional growth of the airway. We applied readily available bioresorbable plates that were custom-molded based on the location, shape, and length of the collapsing airway in selected patients presenting with severe tracheobronchomalacia from loss of structural support and/or cartilage deformation. Further study that includes long-term outcomes are necessary to define the best role for these external splints as part of comprehensive airway management.

Abstract
BACKGROUND Reconstruction of a right aortic arch (RAA) is rarely required in the newborn period and has rarely been reported. METHODS All patients who underwent a RAA repair in the neonatal period from a single institution were retrospectively reviewed. The primary outcome measures included survival, complications, and reintervention. RESULTS Between 1984 to 2020, 15 patients were identified. Nine patients (60%) presented with an interrupted aortic arch (IAA), five (33%) with a hypoplastic arch, and one (7%) with anomalous origin of the brachiocephalic vessels. All patients had associated complex congenital heart disease. Median age at surgery was six days (range, 2-29), median weight 3.11 kg (range, 2.5-4.18). Genetic syndromes were prevalent and 77% of IAA patients had DiGeorge syndrome. Surgical techniques included end-to-side (27%), end-to-end (27%) or side-to-side anastomosis (13%) and placement of an interposition graft (7%). 65% required patch augmentation. Median intensive care unit and total hospital length of stay were 20 days (range, 7 - 92) and 28 days (range, 10 - 240), respectively. At median follow-up of 3.97 years (range, 0.19-36), 13 of 15 (87%) patients were alive. Vocal cord paralysis was found in 27%, hemidiaphragm paralysis in 13% and significant airway compression in 27%. Overall, 27% patients required reintervention on the aortic arch; two surgical and two percutaneous balloon dilation. CONCLUSIONS RAA reconstruction in the newborn period is rare and associated with complex lesions with an acceptable reintervention rate.

Abstract
BACKGROUND The jejunal interposition is our preferred esophageal replacement route when the native esophagus cannot be reconstructed. We report the evolution of our approach and outcomes. METHODS The study was a single-center retrospective review of children undergoing jejunal interposition for esophageal replacement. Outcomes were compared between historical (2010-2015) and contemporary cohorts (2016-2019). RESULTS Fifty-five patients, 58% male, median age 4 years (interquartile range 2.4-8.3), with history of esophageal atresia (87%), caustic (9%) or peptic (4%) injury, underwent a jejunal interposition (historical cohort n = 14; contemporary cohort n = 41). Duration of intubation (11 vs 6 days; P = .01), intensive care unit (22 vs 13 days; P = .03), and hospital stay (50 vs 27 days; P = .004) were shorter in the contemporary cohort. Anastomotic leaks (7% vs 5%; P = .78), anastomotic stricture resection (7% vs 10%; P = .74), and need for reoperation (57% vs 46%; P = .48) were similar between cohorts. Most reoperations were elective conduit revisions. Microvascular augmentation, used in 70% of cases, was associated with 0% anastomotic leaks vs 18% without augmentation; P = .007. With median follow-up of 1.9 years (interquartile range 1.1, 3.8), 78% of patients are predominantly orally fed. Those with preoperative oral intake were more likely to achieve consistent postoperative oral intake (87.5% vs 64%; P = .04). CONCLUSION We have made continuous improvements in our management of patients undergoing a jejunal interposition. Of these, microvascular augmentation was associated with no anastomotic leaks. Despite its complexity and potential need for conduit revision, the jejunal interposition remains our preferred esophageal replacement, given its excellent long-term functional outcomes in these complex children who have often undergone multiple procedures before the jejunal interposition.

Abstract
Tracheobronchomalacia (TBM) is an excessive dynamic narrowing of the airway that is greatest with increased mediastinal pressure such as coughing, Valsalva, and forced expiration. Airway compression and/or cartilage malformation is a fixed or static narrowing of the airway typically caused by great vessel malposition and/or abnormalities and may also contribute to airway narrowing. Although imprecise and misleading, the term TBM is often used to represent both problems, static and dynamic airway narrowing, which only serves to confuse and may mislead the treatment team into ineffective therapies. The consequences of airway narrowing caused by dynamic TBM and/or static compression includes a range of clinical signs and symptoms, depending on the location, extent, and severity of the airway collapse. All patients with mild to severe TBM benefit from medical management to optimize airway clearance of mucus. The milder cases of TBM may become asymptomatic with this therapy, allowing time for the child to grow and the airway to enlarge without the consequences of recurrent infections. In cases of more severe TBM with clinical sequelae, more aggressive management may be warranted. Multiple options for surgical intervention are available. This article discusses the details of clinical presentation, evaluation, diagnosis, and a variety of treatments.

Abstract
Aim: To identify the risk factors associated with the development of tracheobronchomalacia (TBM) in preterm infants with bronchopulmonary dysplasia (BPD). Methods: This was a retrospective cohort study using chart reviews of preterm infants born at ≤ 36 week's gestation who underwent flexible fiberoptic bronchoscopy in a tertiary pediatric referral center between January 2015 and January 2020. Indications for the bronchoscopy examination included lobar atelectasis on plain chest film, persistent CO2 retention, recurrent extubation failure, or abnormal breathing sounds such as wheeze or stridor. Optimal cutoff values for each risk factor were also determined. Results: Fifty-eight preterm infants with BPD were enrolled, of whom 29 (50%) had TBM. There were no significant differences in gestational age and birth weight between those with and without TBM. Significantly more of the patients with TBM had severe BPD compared to those without TBM (68.9 vs. 20.6%, p < 0.001). Clinical parameters that were significantly different between the two groups were included in multivariate analysis. Among these factors, severe BPD was the most powerful risk factor for the development of TBM (odds ratio 5.57, 95% confidence interval 1.32-23.5, p = 0.019). The areas under the receiver operating characteristic curves for peak inspiratory pressure (PIP) and the duration of intubation were 0.788 and 0.75, respectively. The best predictive cutoff values of PIP and duration of intubation for TBM were 18.5 mmHg and 82 days, respectively. Conclusion: Preterm infants with severe BPD are at high risk for the development of TBM, and the risk is even higher in those who receive a higher PIP or are intubated for longer. Bronchoscopy examinations should be considered for the early diagnosis and management of TBM in infants with these risk factors.

Abstract
Tracheobronchomalacia is a condition of dynamic collapse of the trachea and mainstem bronchi. The clinical significance of tracheobronchomalacia depends on its severity. Mild cases may be medically managed with limited symptomology, while severe cases require advanced therapies, lengthy hospital stays, and carry significant morbidity and mortality. Current therapies for severe tracheobronchomalacia include tracheostomy with prolonged mechanical ventilation, aortopexy, tracheobronchopexy, and intraluminal metallic, silicone, or bioresorbable stents. Three-dimensional (3D)-printed, patient-specific, bioresorbable airway splinting is a novel treatment option that is undergoing investigation in a cohort of critically ill children with severe tracheobronchomalacia. At the time of our last review of our data, 29 splints had been implanted in 15 children with intrathoracic tracheobronchomalacia. The median follow-up was 8.5 months. There were 12 long-term survivors, and all but one lived at home. This article discusses the details of our institution's development and use of 3D-printed, patient-specific, bioresorbable splints for treatment of severe tracheobronchomalacia in the pediatric population.

Abstract
Cough is a common presenting symptom for patients in a primary care setting. Chronic cough is defined as a cough lasting for more than 8 weeks. The most common causes of chronic cough are upper airway cough syndrome, asthma, and gastroesophageal reflux disease. Detailed history and physical examination are critical in identifying potential etiologies of cough. When there is no prevailing diagnosis, step-wise empiric trial of medication is a strategic and cost-effective approach. Certain features of chronic cough should provoke an expedited and invasive diagnostic strategy. Effectively treating patients with chronic cough has a high impact on quality of life.

Abstract
BACKGROUND Tracheobronchomalacia and airway obstruction from severely dilated pulmonary arteries in tetralogy of Fallot with absent pulmonary valve (TOF-APV) has been associated with high rates of respiratory failure and mortality (15% to 25%). It is not known whether aggressive pulmonary artery (PA) or direct airway intervention during early definitive cardiac repair improves outcomes. METHODS A retrospective observational study was made of all patients undergoing surgical repair for TOF-APV at our center between 2006 and 2018. RESULTS Twenty patients underwent repair at a median age of 51 days and PA Z-scores of 8.1. Twelve patients had a valve implanted, 6 of whom required reoperation for valve replacement at a median of 9 months (range, 3 to 28) compared with 8 who had initial transannular patch, and only 1 patient required subsequent valve replacement (P < .05). Seven patients had central PAs replaced with thin-walled Gore-Tex (WL Gore, Flagstaff, AZ) grafts; none of these required PA reoperation during a median follow-up of 26.5 months, whereas 3 of 13 patients who did not have PA replacement with Gore-Tex required subsequent PA reoperation (P < .05). Concomitant airway interventions (eg, tracheobronchopexy/plasty) were performed in 4 patients and none required subsequent airway interventions, whereas 2 patients not having initial airway intervention required subsequent tracheopexy (P < .05). Three patients in the cohort eventually required tracheostomy (15%), and 2 patients died (10%; on postoperative days 30 and 326); none had received initial airway intervention. CONCLUSIONS Pulmonary artery replacement and aggressive direct airway management at initial definitive repair of cardiac TOF-APV can be performed safely with acceptable survival outcomes and low rates of airway and PA reintervention.

Abstract
AIM Symptomatic tracheobronchomalacia can be fatal. Successful treatment includes aortopexy. We report outcomes of the thoracoscopic approach in a single centre. METHODS All patients undergoing thoracoscopic aortopexies from 2009 to 2018 were retrospectively reviewed. Data was reported as median (interquartile range). Risk factors for subsequent tracheostomy were analyzed with logistics regression model, p < 0.05 as significant. RESULTS Twenty-one patients with mid to distal tracheomalacia (n = 17) and bronchial involvement (n = 4) were determined on bronchoscopy, tracheobronchogram, or CT thorax. Preoperative patient demographics and comorbidities, e.g., gastro-oesophageal reflux disease, prematurity, and cardiac anomalies were recorded. Indications for thoracoscopic aortopexy were apparent life-threatening event(s) (n = 14), recurrent chest infections (n = 5), and failure to wean invasive ventilation (n = 2). Thoracoscopic aortopexies (n = 20) with conversion to open (n = 1) were performed. Intraoperative bleeding (n = 2) occurred, and chest tube (n = 1) was inserted for monitoring. Intraoperative bronchoscopy (n = 17) confirmed improvement of tracheomalacia. Anesthetic time was 140 (90-160) minutes. Postoperatively, 2 patients had dehiscence of the aorta from the sternum. They underwent redo open aortopexy with posterior tracheopexy, and 1 required subsequent tracheostomy. Another 2 patients required tracheostomies. Potential risk factors for subsequent tracheostomy were investigated, and only the association of tracheobronchomalacia was close to significance (OR 16 (95% CI 0.95-267.03), p = 0.05). Follow up duration was 365 (72-854) days. Symptoms resolution occurred in n = 17 (81%) of patients. CONCLUSION Different modalities were used to delineate the site of tracheobronchomalacia and its etiology. Tracheomalacia with bronchial involvement may be a risk factor for subsequent tracheostomy. LEVEL OF EVIDENCE Level 3 (Case Series).

Abstract
Tracheobronchomalacia (TBM) refers to airway collapse due to typically excessive posterior membrane intrusion and often associated with anterior cartilage compression. TBM occurs either in isolation or in association with other congenital or acquired conditions. Patients with TM typically present non-specific respiratory symptoms, ranging from noisy breathing with a typical barking cough to respiratory distress episodes to acute life-threatening events and recurrent and/or prolonged respiratory infections. There are no definitive standardized guidelines for the evaluation, diagnosis, and treatment of TBM; therefore, patients may be initially misdiagnosed and incorrectly treated. Although milder cases of TBM may become asymptomatic as the diameter of the airway enlarges with the child, in cases of severe TBM, more aggressive management is warranted. This article is an overview of the clinical presentation, evaluation, diagnosis, medical management, and surgical treatment options in pediatric tracheomalacia.
