Pyloric Stenosis
The pyloric muscle dimensions of 1400 consecutive newborns were measured at birth (ie, prospectively) by ultrasonography. Nine infants subsequently developed pyloric stenosis. All diagnoses were proved at surgery. The pyloric measurements of the infants with pyloric stenosis did not differ from normal at birth, but there was significant increase at the time of diagnosis. "We conclude that infantile hypertrophic pyloric stenosis should no longer be referred to as `congenital' pyloric stenosis, although the true etiology of this acquired condition remains to be elucidated."
