Pyloric stenosis

The pylorus is the valve found where the stomach and the small intestine meet. Sometimes a child’s pylorus muscles become thickened and the enlarged valve prevents food from passing into the small intestine. This condition is called pyloric stenosis.

UF surgeons treat pyloric stenosis through a procedure known as a pyloromyotomy, in which they cut the muscles of the pylorus to loosen the opening and allow food to pass. For children who do not tolerate general anesthesia, a treatment known as balloon dilation is an option, although it is considered less effective.
