Gastric outlet obstruction in a cystic fibrosis patient

Eosinophilic gastritis is an uncommon disease characterized by focal or diffuse eosinophilic infiltration of the gastric wall and is usually associated with dyspepsia and peripheral eosinophilia. The stomach and small bowel are usually involved in eosinophilic gastrointestinal disorder (EGID) which is called Eosinophilic Gastroenteritis (EG), but the esophagus and colon are rarely involved. Gastrointestinal obstruction rarely occurs with eosinophilic gastroenteritis and usually happens when the eosinophils predominantly involve the muscular layer of the gastrointestinal tract. Here we present a case of a Cystic Fibrosis (CF) patient in which gastric outlet obstruction (GOO) is caused by eosinophilic gastritis and treated successfully with steroids.
