Gold standard of choice:

• Ultrasonography is the gold standard test for the diagnosis of infantile pyloric stenosis.

• The following result of ultrasonography is confirmatory of infantile pyloric stenosis:
  • Thickened prepyloric antrum bridging the duodenal bulb
  • Distended stomach
  • Crowded intervening mucosa that protrudes into the distended portion of the antrum (nipple sign)
