OBJECTIVE: The solution of severe tracheobronchial obstructions in early childhood means a great challenge. Biodegradable stents were intended to be a minimally invasive temporary solution which may decrease the number of interventions and limit the possible complications of stenting procedures. However, our first experiences have brought out a new, - especially in childhood - potentially life-threatening complication of this concept. METHODS: Five SX-ELLA biodegradable polydioxanone stents was applied in three patients because of severe tracheobronchial obstruction: congenital tracheomalacia (7 day-old), acquired tracheomalacia (10 month-old), and congenital trachea-bronchomalacia (10 month-old)...

OBJECTIVES: Complete vascular rings are rare and cause tracheoesophageal compression. Following surgical division, some patients have persisting tracheomalacia. We aim to assess the long-term outcomes of complete vascular ring division. METHODS: All patients (n = 132) who underwent surgical division of a complete vascular ring between 1978 and 2014 were identified from the hospital database and retrospectively reviewed. RESULTS: Complete vascular rings consisted of a double aortic arch (n = 80), right aortic arch with an aberrant subclavian artery and left ligamentum arteriosum (n = 50), right aortic arch with mirror image branching and left ligamentum arteriosum (n = 1), and a left aortic arch with right descending aorta and right ligamentum arteriosum (n = 1)...

IMPORTANCE: The etiology of recurrent croup is often anatomic. Currently there is no set criteria for determining who should undergo diagnostic bronchoscopy and which patients are at most risk for having a clinically significant finding. Few studies have addressed these questions. OBJECTIVE: To identify risk factors for clinically significant findings on bronchoscopy in children with recurrent croup and the frequency of bronchoscopy findings in general. DATA SOURCES: PUBMED, Ovid MEDLINE, EMBASE...

INTRODUCTION: With the advent of improved neonatal and pediatric intensive care management, tracheostomy is increasingly performed in children requiring prolonged ventilation. Even though tracheostomy is generally a safe procedure, there remains mortality and morbidity associated with it. OBJECTIVE: We report a rare complication of a tracheostomy tube resulting in extensive erosion and posterior tracheal false pouch secondary to a large tracheostomy tube and high positive end expiratory pressure in a 12-month-old infant...

Spontaneous pneumomediastinum in children is a very rare, benign entity. Recurrent episodes are exceptional. Identifying an underlying trigger is crucial, and very often, spontaneous pneumomediastinum occurs in association with an asthma exacerbation. We report the case of a patient in which we hypothesize that an underlying tracheomalacia can be held responsible for the recurrent pneumomediastinum, which is to this date the first case with this assumption.

The aim of this study was to: (1) find out whether laryngomalacia (LM) types are related to clinical course; (2) which patients with LM are at higher risk of other airway malacia [tracheomalacia (TM) and/or bronchomalacia (BM)]; and (3) evaluate the prevalence of LM in our region. Patients with established LM diagnosis and complete clinical and endoscopy records were enrolled. They were classified into different LM types according to classification based on the side of supraglottic obstruction. One hundred ten children were included...

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...

PURPOSE: Recurrent trachea-esophageal fistula (recTEF) is a frequent (5%-10%) complication of congenital TEF (conTEF) and esophageal atresia (EA) repair. In addition, postoperative acquired TEF (acqTEF) can occur in addition to or even in the absence of prior conTEF in the setting of esophageal anastomotic complications. Reliable repair often proves difficult by endoluminal or standard surgical techniques. We present the results of an approach that reliably identifies the TEF and facilitates airway closure as well as repair of associated tracheal and esophageal problems...

Patients with diffuse airway instability due to tracheobronchomalacia or excessive dynamic airway collapse are typically highly symptomatic, with marked dyspnoea, recurrent bronchopulmonary infections and excruciating intractable cough. Silicone stents achieve immediate symptom control, but are - due to the typical complications associated with stent treatment - usually not an option for long-term treatment. The aim of surgical intervention is definitive stabilisation of the trachea and of both main bronchi by posterior splinting of the Paries membranaceus with a polypropylene mesh...

BACKGROUND: Wheezing is a common symptom in early childhood. However, refractory wheezing is difficult to treat, and it may thus account for extensive use of medical resources. It is therefore important to improve our understanding of the pathophysiology of refractory childhood wheezing. METHODS: In this descriptive study, we studied 156 children with refractory wheezing using fiberoptic bronchoscopy and bronchoalveolar lavage (BAL), and compared the results with a control group of 46 children with various pulmonary diseases but no wheezing...

PURPOSE: The aim of this study is to identify the risk factors for esophageal anastomotic stricture (EAS) and/or anastomotic leakage (EAL) after primary repair of esophageal atresia with tracheoesophageal fistula (EA/TEF) in infants. METHODS: A retrospective chart review of 52 patients with congenital EA/TEF between January 2000 and December 2015 was conducted. Univariate and multivariate analyses were performed to identify the risk factors for anastomotic complications...

Several different lysosomal storage diseases, mainly mucopolysaccharidosis (MPS) type I, II, and VI, are complicated by severe obstruction of the upper airways, tracheobronchial malacia, and/or stenosis of the lower airways. Although enzyme replacement therapies (ERTs) are available, the impact of these on tracheobronchial alterations has not been reported. By extending the life expectancy of MPS patients with ERTs, airway problems may become more prevalent at advanced ages. These airway abnormalities can result in severe, potentially fatal, difficulties during anesthetic procedures...

In the past decades improved surgical techniques and better neonatal supportive care have resulted in reduced mortality of patients with esophageal atresia (EA), with or without tracheoesophageal fistula, and in increased prevalence of long-term complications, especially respiratory manifestations. This integrative review describes the techniques currently used in the pediatric clinical practice for assessing EA-related respiratory disease. We also present a novel algorithm for the evaluation and surveillance of lung disease in EA...

The term vascular ring refers to congenital vascular anomalies of the aortic arch system that compress the esophagus and trachea, causing symptoms related to those two structures. The most common vascular rings are double aortic arch and right aortic arch with left ligamentum. Pulmonary artery sling is rare and these patients need to be carefully evaluated for frequently associated tracheal stenosis. Another cause of tracheal compression occurring only in infants is the innominate artery compression syndrome...

Tracheomalacia (TM) is defined as an increased collapsibility of the trachea due to structural anomalies of the tracheal cartilage and/or posterior membrane. Tracheomalacia has a wide range of etiologies but is most commonly present in children born with esophageal atresia and tracheal esophageal fistula. Clinical symptoms can range from minor expiratory stridor with typical barking cough to severe respiratory distress episodes to acute life-threatening events (ALTE). Although the majority of children have mild-to-moderate symptoms and will not need surgical intervention, some will need life-changing surgical treatment...

Pneumonia is one of the most serious diseases for children, with which lung microbiota are proved to be associated. We performed 16S rDNA analysis on broncho-alveolar lavage fluid (BALF) for 32 children with tracheomalacia (C group), pneumonia infected with Streptococcus pneumoniae (S. pneumoniae) (D1 group) or Mycoplasma pneumoniae (M. pneumoniae) (D2 group). Children with tracheomalacia held lower microbial diversity and accumulated Lactococcus (mean ± SD, 45.21%±5.07%, P value <0.05), Porphyromonas (0...
