Why is gastric outlet obstruction important to pediatric surgeons?

Gastric outlet obstruction is defined as any condition that restricts the passage of normal gastric contents through the pylorus into the duodenum. Although rare, it typically requires surgical intervention such that pediatric surgeons need to be familiar with the different etiologies in order to select the appropriate treatment. A wide variety of pathology, both congenital and acquired, can cause harm and even be fatal in this patient population. The most prevalent cause is idiopathic hypertrophic pyloric stenosis (IHPS). While IHPS is common, there are many other causes which, while not as frequent, are important to consider in the differential when evaluating a child with the signs and symptoms of gastric outlet obstruction.
