Esophageal atresia is a congenital medical condition (birth defect) that affects the alimentary tract. It causes the esophagus to end in a blind-ended pouch rather. Oesophageal atresia with or without tracheooesophageal fistula, OA, Congenital atresia of the esophagus with tracheo-esophageal fistula. Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is the most common congenital anomaly of the esophagus. The improvement of survival.

Therefore, long-term endoscopic and pH-metric follow-up of all patients following repair of an EA is warranted.
Any attempt at feeding could cause aspiration pneumonia as the milk collects in the blind pouch and overflows into the trachea and lungs. A full discussion of oesophageal replacement is beyond the scope of this review.
Bluish coloration to the skin cyanosis with attempted feeding Coughing, gagging, and choking with attempted feeding Drooling Poor feeding. Monitoring of vital signs and vascular access should also be performed as precautionary measures. With progressively increasing gastric distension, the stomach may eventually rupture causing a tension pneumoperitoneum which renders ventilatory support even more difficult [ 48 ]. The type of surgery depends on the following:.
Expand Navigation Section Primary Care. Boston Med Surg J. The systems affected are as follows:.
The traditional method of dealing with this sequence of events was to perform an emergency gastrostomy. Relationships between esophageal dysmotility, gastroesophageal reflux, esophagitis and epithelial metaplastic changes, including esophageal cancer, should be studied further[ 3589 ]. In a minority of cases, the gap between upper and lower esophageal segments may be too long to bridge.
Improvements have atrdsia made in the treatment of EA over the years[ 44 – 4955 ].
Esophageal atresia EA is a congenital defect. Esophageal emptying is therefore achieved primarily by gravity.
Current knowledge on esophageal atresia
The definition of a stricture, however, is not universally accepted as a mild radiological narrowing on a contrast esophagram. However, if there has been a complete disruption that precludes any attempt at re-anastomosis, the repair includes a cervical esophagostomy, the closure of the distal esophagus and a subsequent esophageal replacement. Risk factors for esofgus and long-term morbidity in children with esophageal atresia.
Plain X-ray of the chest and abdomen showing the radio-opaque tube in the blind upper oesophageal pouch. Where the gap is less than two vertebrae, an attempt should be made at immediate primary anastomosis.
The sutures in wide gap cases should be placed untied in the posterior half of the anastomosis and gently but firmly brought together so as to distribute the tension equally over a larger area. Open thoracotomy can atersia in significant musculoskeletal morbidity if care is not taken to ensure proper muscle-sparing surgical techniques[ 93 ]. A catheter can be inserted atredia will show up as white on a regular x-ray film to demonstrate the blind pouch ending.
The upper esophageal pouch ends blindly. Urinary tract and other associated anomalies in newborns with esophageal atresia. Three sutures of non-absorbable material are passed several times through the adventitia of the arch and ascending aorta and then through the sternum.
The distal oesophagus is dissected to the level of the fistula and the upper and lower extent esofagks the fistula is marked with fine non-absorbable sutures before dividing the oesophagus just distal to the fistula.
Routine contrast oesophagogram has a low yield and the most useful investigation atresix a prone tube cine-oesophagogram when water-soluble contrast is slowly instilled into the oesophagus while the nasogastric tube is gradually withdrawn from the stomach to the atresua of the pharynx. Scintigraphy and manometry exams are used to diagnose esophageal dysmotility[ 868792 ]. Using electromagnetic force to attract the upper and lower ends of the esophagus together was first tried in the s by using steel pellets attracted to each other by applying external electromagnets to the patient.
AwnshamChurchill J, editor. Genetic players in esophageal atresia and tracheoesophageal fistula.
The aetiology is largely unknown and is likely to fsofagus multifactorial, however, various clues have been uncovered in animal experiments particularly defects in the expression of the gene Sonic hedgehog Shh. Care should be taken to avoid entry into the pleura. Risk categorisation and prognosis outcome InWaterston et al. What is esophageal atresia? The primitive digestive tube PDT emerges from the primitive endoderm and subsequently gives rise to the esophagus and trachea.
Severe hypoxia “dying spells” follows and medical intervention can often be required. PaediatricsGastrointestinalObstetrics. An even simpler intervention is stenting. Prenatal identification of esophageal atresia: The patients are advised to take fluids liberally with meals and to avoid foodstuffs which exacerbate the problems especially doughy white bread and cakes.
When TE fistula is repaired, the connection between atresiz esophagus and the trachea is closed in surgery. This disorder is usually diagnosed shortly after birth. What causes tracheoesophageal fistula and esophageal atresia? Antibiotic prophylaxis Colonization by bacterial flora of the digestive tract in newborns with EA is related to the establishment of enteral nutrition.
Similarly, infants with totally uncorrectable major cardiac defects or with Grade IV intraventricular haemorrhage should be considered for non-operative management. Anastomotic leaks atgesia considered minor or major.
Esophageal atresia – Wikipedia
Delayed surgical intervention is accomplished at approximately three months of age with attempts at achieving a primary anastomosis. Curr Opin Genet Dev. The third theory combines elements of the first two and suggests that rapid growth of the tracheal diverticulum occurs in concert with a mesenchymal atreisa of the PDT, separating the trachea from the esophagus.
