Endoscopy Challenge #2 - Jan '10

Histologic evaluation of this region revealed gastric antral type mucosa with increased eosinophils seen deep in the mucosa and submucosa.

A diagnosis of eosinophilic gastric outlet obstruction was made and amino acid based formula feedings were initiated through the transpyloric tube. Within 7 days the gastric outlet obstruction resolved and by follow up at 6 weeks the child was tolerating elemental gastric feedings.
