EA/TEF is a basic concept in pediatric surgery.
Host summaryJill Knepprath summarizing a resource · not cited in answers
In normal anatomy, the esophagus goes straight down to the stomach with no atresia or interruptions, and the trachea goes straight down to the lungs with no connections between the two.
Host summaryJill Knepprath summarizing a resource · not cited in answers
Type A EA/TEF consists of esophageal atresia proximally and distally in the esophagus, preventing solids and liquids from reaching the stomach, with no connection between esophagus and trachea.
Host summaryJill Knepprath summarizing a resource · not cited in answers
Type B EA/TEF has distal esophageal atresia and a proximal fistula, allowing solids and liquids to enter the trachea while the stomach remains empty.
Host summaryJill Knepprath summarizing a resource · not cited in answers
Type C EA/TEF is the most common type.
Host summaryJill Knepprath summarizing a resource · not cited in answers
Type C EA/TEF has proximal esophageal atresia and a distal fistula, allowing air to reach both lungs and stomach while solids and liquids cannot reach the stomach.
Host summaryJill Knepprath summarizing a resource · not cited in answers
Type D EA/TEF has both a distal fistula and a proximal fistula, allowing solids and liquids into the trachea and air into both lungs and stomach.
Host summaryJill Knepprath summarizing a resource · not cited in answers
Type E EA/TEF has no atresia but does have a tracheoesophageal fistula, which is often pretty high.
Host summaryJill Knepprath summarizing a resource · not cited in answers
Type E EA/TEF is also known as H-type because of its anatomical appearance.
Host summaryJill Knepprath summarizing a resource · not cited in answers
Type E (H-type) EA/TEF has the best results and is usually the easiest to fix.
Host summaryJill Knepprath summarizing a resource · not cited in answers
Children with Type E (H-type) EA/TEF may present with symptoms later because they are still able to get solids and liquids down to the stomach and air to the lungs.
