(mcq) The most common pattern of oesophageal atresia is associated with (tricky one):
- A- Contrast study showing fistula between trachea and upper esophagus.
- B- Gaseless abdomen.
- C- Trachea is non aerated due to congenital canalization defect.
- D- Lower lobe pneumonia is commonly found (According to Danhert, upper lobe pneumonia).
- E- Xray chest and abdomen can be normal.
The most common pattern of esophageal atresia is indeed associated with E. X-ray chest and abdomen can be normal.
While other options might be present in some cases, normality on X-ray is the most characteristic and challenging aspect of the most common type of esophageal atresia.
Here's why the other options are less accurate:
A. Contrast study showing fistula between trachea and upper esophagus:
This describes a specific type of esophageal atresia with tracheoesophageal fistula (TEF), but it's not the most common pattern.
B. Gaseless abdomen:
While a gaseless abdomen can be seen in some cases, it's not always present and isn't specific to the most common type.
C. Trachea is non-aerated due to congenital canalization defect:
This is a rare condition, not associated with the most common pattern of esophageal atresia.
D. Lower lobe pneumonia is commonly found (According to Danhert, upper lobe pneumonia):
This can occur in some cases due to aspiration, but it's not the most specific finding and may not be present in all cases.
Therefore, the ability of the most common pattern of esophageal atresia to present with normal X-ray findings makes it the most tricky and important aspect to remember. This normal appearance can lead to delays in diagnosis, highlighting the importance of considering other clinical signs and symptoms.
