Question

what are the key findings on abdominal X-ray (AXR) that differentiate esophageal atresia from tracheoesophageal (TE) fistula?

Answer 1

The key findings on abdominal X-ray (AXR) that differentiate esophageal atresia from tracheoesophageal (TE) fistula include a dilated stomach, absent gas in the abdomen, and polyhydramnios.

Step-by-step explanation:

The key findings on abdominal X-ray (AXR) that differentiate esophageal atresia from tracheoesophageal (TE) fistula include:

1. Dilated stomach: In esophageal atresia, the stomach is typically dilated and air-filled due to the inability of the swallowed air to pass through the esophagus.
2. Absent gas in the abdomen: In tracheoesophageal fistula, air may be seen in the abdomen as it leaks from the trachea into the esophagus and then into the gastrointestinal tract.
3. Polyhydramnios: This is the presence of excessive amniotic fluid and is more commonly associated with esophageal atresia.

By identifying these key findings on an abdominal X-ray, medical professionals can distinguish between esophageal atresia and tracheoesophageal fistula.
