Insights
Ultrasound (US) is a highly accurate diagnostic tool for hypertrophic pyloric stenosis (HPS) in infants. This study found US to be a reliable method for diagnosing HPS, with no false positives or negatives in suspected cases.
Area of Science:
- Pediatric Surgery
- Diagnostic Imaging
- Gastroenterology
Background:
- Hypertrophic pyloric stenosis (HPS) is a common surgical condition in neonates.
- Vomiting and a palpable pyloric mass are typical clinical signs.
- Traditional diagnostic methods include upper gastrointestinal tract studies.
Purpose of the Study:
- To evaluate the diagnostic efficacy of ultrasound (US) for suspected hypertrophic pyloric stenosis (HPS).
- To assess the accuracy of US in identifying HPS in infants.
Main Methods:
- Retrospective review of 27 infants with clinical suspicion of HPS.
- Diagnosis confirmed or excluded using ultrasound (US).
Main Results:
- Ultrasound (US) identified hypertrophic pyloric stenosis (HPS) in 17 infants.
- US results were negative in 10 infants.
- The study reported zero false positive or false negative diagnoses with US.
Conclusions:
- Ultrasound (US) is a highly recommended and accurate diagnostic method for infants with suspected hypertrophic pyloric stenosis (HPS).
- US has become the preferred imaging modality for diagnosing HPS.
Abstract:
Hypertrophic pyloric stenosis (HPS) is one of the most common causes of abdominal surgery during the first weeks of life. The primary cause of the muscular hypertrophy is unknown and the pathogenesis is obscure. Clinically, vomiting is always present and sometimes there is a palpable pyloric mass (olive). Upper gastrointestinal tract study with barium has been the most usual method for the diagnosis. Since the first report of the use of ultrasound (US) in the diagnosis of HPS in 1977, this technique has been widely used and accepted, being by now, the diagnostic imaging examination of choice for infants in whom this abnormality is suspected. This is our experience with the use of US in 27 infants with clinically suspected HPS. In 17 cases there was US evidence of HPS and in 10 patients results were negative. We did not have false positive neither false negative results. We strongly recommend this diagnostic method for all infants under clinical suspicion of HPS.
