title: Foveolar cell hyperplasia at the pyloric canal: an unusual cause of gastric outlet obstruction in 3 young children.
abstract: Foveolar cell hyperplasia (FCH) in the pylorus is rare in children. Between January 1993 and December 2008, 3 children with pyloric canal FCH presented with gastric outlet obstruction and/or anemia and underwent operation because a clear diagnosis could not be established with conservative management. The median age of the children was 18 months. The onset of FCH at the pyloric canal is problematic, and its diagnosis is difficult to make in pediatric patients. Exploratory laparotomy is a reasonable method of establishing the diagnosis and managing the condition.
