The clinical presentation of an H type fistula is different than the other fistulae because it does not share the common presenting signs associated with atretic esophagus. [pedclerk.uchicago.edu]

Isolated tracheoesophageal fistula (TEF) (H-type fistula) Recurrent pneumonia may be present, with a widespread pneumonia pattern. Fistula delineation can be difficult. Excessive air may be present in the esophagus. [thehealthscience.com]

If there is a TOF present, saliva ± gastric secretions can pass directly to the bronchial tree. H-type fistulae usually present later in infancy as there is no 'blind end' to the oesophagus and the child is able to feed. [patient.info]

Conversely, when the fetus presents a low-level obstruction, none of these enzymes are present in the AF. [nature.com]

Therefore, the aim of present study is to evaluate postoperative outcomes of patients treated for Gross type B-D and E EA, on regards of their cervical surgery. [moh-it.pure.elsevier.com]

• Asymptomatic

  Esophagography can be used to demonstrate an asymptomatic leak. In addition, a dilated proximal esophageal segment (particularly if the repair included myotomy) and distal esophageal stenosis are noted postoperatively. [thehealthscience.com]

• Cough

  RESULTS: The clinical picture consisted in a coughing bout and cyanosis after each feeding. Thoracic and abdominal imaging showed aspiration pneumonia, atelectasis, and gas within the colon. [ncbi.nlm.nih.gov]

  They often present later with milder coughing or choking with feeds or reflux. Normal upper GI’s may miss isolated TEF. Diagnosis is therefore made with either a “pullback” esophagram using a feeding tube, or rigid bronchoscopy. [surgery4children.com]

  Tracheomalacia can lead to a 'TOF cough' (a harsh barking cough). Recurrent chest infections can lead to bronchiectasis and irreversible lung damage. Respiratory morbidity tends to improve as the child ages. [patient.info]

  The neonate with EA typically has frothing and bubbling at the mouth and nose after birth as well as episodes of coughing, cyanosis, and respiratory distress. Feeding exacerbates these symptoms, causes regurgitation, and may precipitate aspiration. [easypediatrics.com]

  When fed, these infants swallow normally but begin to cough and struggle as the fluid returns through the nose and mouth. [en.wikipedia.org]

• Paresis

  In children operated for esophageal atresia (EA) and/or TEFs, follow-up deglutitive and respiratory symptoms may occur and should be evaluated with videofluoroscopy. [12] Vocal cord paresis/paralysis may occur more often in patients treated for esophageal [emedicine.medscape.com]

  Morini et al. studied 174 patients with treated EA/TEF and found that 7 (4%) of patients had vocal cord paresis. [frontiersin.org]

Preoperative Planning In a term baby, EA or EA/TEF is rarely an emergency and there is usually adequate time to complete the preoperative workup and plan the operative approach. [basicmedicalkey.com]

In both patients, esophageal manometry was part of the diagnostic workup. Information was gathered from the medical charts: demographic, medical history, symptomatology before HREM. [journals.lww.com]

Not included in classification by Ladd 4% Treatment [ edit ] Treatments for the condition vary depending on its severity. [en.wikipedia.org]

Standard Therapies Treatment Treatment may require the coordinated efforts of a team of specialists. [rarediseases.org]

Although EA surgical treatment is well established, the outcome of EA with proximal fistula (type B and D EA) or isolated H-type fistula (type E EA) is poorly explored. [moh-it.pure.elsevier.com]

Treatment Initial treatment of EA/TEF should involve stabilization of the infant prior to transfer to a tertiary care center with pediatric surgery and intensive care services. [pedclerk.uchicago.edu]

Furthermore, evolution in medical and surgical management has vastly improved the prognosis for these lesions since the first reported survivor nearly 80 years ago. [neoreviews.aappublications.org]

Prognosis: Survival is primarily dependent on gestation at delivery and the presence of other anomalies. [fetalmedicine.org]

What is my baby's long-term prognosis? The prognosis for survival for an isolated TEF/EA is excellent. An associated anomaly can alter that prognosis. [chw.org]

The prognosis in these fetuses depends on the associated abnormalities, the birth weight and whether the neonate will develop pneumonia secondary to aspiration. References: Hertzberg BS. [fetalsono.com]

Prognosis This depends on associated anomalies and their complications. Overall survival now exceeds 90% in dedicated centres. [ 14 ] Associated congenital heart defects and low birth weight can affect survival. [patient.info]

Its etiology is obscure. Diagnosis is difficult but must be made early. PURPOSE: To study the clinical, radiological, and evolutionary sights of this malformation. [ncbi.nlm.nih.gov]

Although the absolute etiology of these lesions is yet to be determined, much has been learned from embryologic studies and syndromic associations. [neoreviews.aappublications.org]

Definition A tracheo-esophageal fistula (TEF) is a congenital defect that is thought to be a result of a foregut malformation of uncertain etiology around the 4th to 5th week of gestation age. [openanesthesia.org]

Embryology It remains controversial as to the exact etiology for the development of EA/TEF. Around the fourth week of gestation, the foregut begins to differentiate into a dorsal esophageal part and a ventral respiratory segment. [basicmedicalkey.com]

We recommend in all cases of esophageal atresia that a respiratory deterioration be fully investigated, with consideration of the possibility of a tracheoesophageal fistula as the etiology. [springerplus.springeropen.com]

The aim of this study was to find a pathophysiological explanation for this dissociated biochemical pattern observed in EA. [nature.com]

Pathophysiology TE fistulas occur due to abnormal septation of the caudal foregut during the fourth and fifth weeks of embryonic development. [pedclerk.uchicago.edu]

[…] deeply disorganized in these young patients who had no other reasons (no esophagitis, no congenital stenosis, no abnormal LES relaxation, and no surgical insult) to explain the dysmotility, we believe that these findings provide important elements in the pathophysiology [journals.lww.com]

This suggests that distal esophageal dysmotility, rather than pooling over the anastomosis, may be a bigger contributor to feeding difficulties in many children and supports imaging to understand the pathophysiology of dysphagia first before dilation [frontiersin.org]

Initially, maintaining a patent airway and preventing aspiration of secretions are paramount. [easypediatrics.com]

The EA / TEF is a condition that endangers life, so affected babies usually require surgery to correct the defect in order to allow food and prevent lung damage from repeated exposure of esophageal fluids. [ivami.com]

GERD may need to be treated with medication, or in severe cases, with surgery to prevent the acid from doing damage to the esophagus or lungs. [eapsa.org]

Suctioning of the blind ending oesophagus is necessary to prevent aspiration and protect the airway. This should continue until surgery is performed. Prophylactic antibiotics may also be needed. [patient.info]
