Abstract
This case report demonstrates a common presentation and classical radiological findings of a duodenal web with a small orifice, but which was unmasked by ingestion of a foreign body, causing acute complete duodenal obstruction.
Highlights
Duodenal web is a rare congenital anomaly related to recanalization failure and incomplete vacuolization during early embryologic foregut development resulting in subsequent partial or complete obstruction [1]
The child had had required two prior hospital admissions for correction of associated dehydration and metabolic disturbances. She re-presented with bilious vomiting, upper abdominal distension and electrolyte imbalance, she was on the 50th percentile for weight
The UGI contrast study showed that contrast medium failed to pass the foreign body which was in the 2nd part of the duodenum (Figures 2 and 3)
Summary
Duodenal web is a rare congenital anomaly related to recanalization failure and incomplete vacuolization during early embryologic foregut development resulting in subsequent partial or complete obstruction [1]. This can be detected during neonatal period but diagnosis can be delayed depending on the degree of stenosis and exacerbation factors. Occurrence at the second part of the duodenum is most frequently seen; representing 85-90% of cases [2]. Common presentations include upper abdominal pain, distension and post-prandial vomiting in a background of failure to thrive [3].
