Congenital oesophageal stenosis.

Area of Science:

• Pediatric Gastroenterology
• Radiology
• Congenital Abnormalities

Background:

• Congenital stenosis of the oesophagus is a condition affecting infants and children.
• Previous literature may underestimate the frequency of this condition.
• Understanding the location and presentation of stenosis is key for diagnosis.

Purpose of the Study:

• To report clinical and radiographic findings in a cohort of 34 pediatric patients with congenital oesophageal stenosis.
• To delineate the common locations and associated symptoms of oesophageal stenosis.
• To provide recommendations for diagnostic evaluation in at-risk populations.

Main Methods:

• Retrospective review of clinical data and radiographic (oesophagram) findings.
• Analysis of observations in 34 infants and children diagnosed with congenital oesophageal stenosis.
• Correlation of stenosis location with presenting symptoms and patient age.

Main Results:

• Congenital oesophageal stenosis is more prevalent than previously reported.
• Lower oesophageal stenosis, typically at the middle-distal junction, is most common, presenting with vomiting.
• High oesophageal stenosis is less frequent, often associated with respiratory distress.

Conclusions:

• Congenital oesophageal stenosis can persist into adulthood with a generally benign course.
• Infants with undigested food vomiting warrant an oesophagram to rule out stenosis.
• Children with oesophageal foreign bodies, especially distally, require follow-up oesophagrams to assess for underlying stenosis.
