C) Pylorus wall measurement of 3mm or greater on ultrasonography
Ultrasound is the most useful diagnostic test to confirm pyloric stenosis, which should be suspected in infants with projectile non-bilious vomiting of all feeds presenting in the first few months of life (classically presents at age 3-6 weeks). Although palpation of an “olive” is pathognomonic, it is often difficult to palpate. Similarly, hypochloremic metabolic alkalosis is a classic, but late finding. In the modern era, pyloric stenosis is usually diagnosed by ultrasonography. The mnemonic pi-loric, with the number pi being 3.1415, can be used to remember that the ultrasound measurements of concern are: pyloric muscle thickness > 3mm, pyloric transverse diameter > 14mm, and pylorus length > 15mm. UGI barium series is rarely done due to the ease of use and accuracy of ultrasonography.
