Duodenal stenosis in a child.

We present a case of incomplete duodenal obstruction having a delayed presentation, making diagnosis and early intervention more challenging. Failure of recanalization of the duodenal lumen during the eighth to tenth week of gestation, results in duodenal atresia. Incomplete recanalization can lead to duodenal stenosis or the presence of a duodenal web. In the absence of other serious anomalies or prematurity, the overall survival for duodenal stenosis or atresia is nearly 100%.
