ABSTRACT
The most common cause of gastric outlet obstruction in neonates and infants is hypertrophic pyloric stenosis. Pyloric web as a cause of gastric outlet obstruction is relatively rare in children and presents with non bilious vomiting, abdominal pain and failure to thrive. The onset of symptoms is usually late with nonspecific symptoms like vomiting and failure to thrive that seems to be due to neuromuscular incoordination. Here we report a 3 year-old boy with prolonged fever, anorexia, and intractable postprandial non bilious vomiting and weight loss since 20 days prior to admission. Barium meal study revealed gastric outlet obstruction with a dilated stomach. The patient underwent laparotomy and pyloric web was confirmed as the cause of the symptoms and Heineke-Mikulicz pyloroplasty led to disappearing of the entire patient's problems
