Evaluation of hypertrophic pyloric stenosis by pediatric emergency physician sonography.

چکیده
OBJECTIVES The objective was to evaluate the accuracy of pediatric emergency physician (EP) sonography for infants with suspected hypertrophic pyloric stenosis (HPS). METHODS This was a prospective observational pilot study in an urban academic pediatric emergency department (PED). Patients were selected if the treating physician ordered an ultrasound (US) in the department of radiology for the evaluation of suspected HPS. RESULTS Sixty-seven patients were enrolled from August 2009 through April 2012. When identifying the pylorus, pediatric EPs correctly identified all 10 positive cases, with a sensitivity of 100% (95% confidence interval [CI] = 62% to 100%) and specificity of 100% (95% CI = 92% to 100%). There was no statistical difference between the measurements obtained by pediatric EPs and radiology staff for pyloric muscle width or length (p = 0.5 and p = 0.79, respectively). CONCLUSIONS Trained pediatric EPs can accurately assess the pylorus with US in the evaluation of HPS with good specificity.

BACKGROUND/PURPOSE Two strategies are commonly used for the initial diagnosis of hypertrophic pyloric stenosis (HPS): (1) physical examination and (2) radiologic evaluation using upper gastrointestinal series (UGI) or sonography. The authors wished to determine the sensitivity and relative cost of each strategy. METHODS The charts of 234 patients presenting over 3 years with a history suggest...
