Hypertrophic pyloric stenosis (HPS) is an acute abdominal emergency in infants that often presents to Emergency Departments. The clinical diagnosis of HPS relies on palpation of an olive-sized mass in the right upper quadrant of an infant with a history of projectile vomiting. However, studies have shown that clinicians cannot detect the olive in 11% to 51% of cases. Ultrasonography is the imaging modality of choice to diagnose HPS. HPS has a highly characteristic sonographic appearance that makes it readily identifiable on ultrasound. To our knowledge, there have been no reports documenting the ability of Emergency Physicians to diagnose HPS using point-of-care ultrasound. We present a multi-center case series (n = 8) of HPS diagnosed by Emergency Physician-performed ultrasound. We review the technique of incorporating point-of-care ultrasound into the physical examination of infants with suspected HPS and discuss the possible role of point-of-care ultrasound in the management of these patients.
