title: Sonographic Diagnosis of Infantile Hypertrophic Pyloric stenosis- Use of Simultaneous Grey-scale & Colour Doppler Examination.
abstract: OBJECTIVE
  To evaluate the accuracy of Ultrasound in the diagnosis of Infantile Hypertrophic Pyloric stenosis, especially with simultaneous use of grey-scale & colour doppler examination of pylorus.
  
  
  METHODS
  Fifty two infants with suspected Infantile Hypertrophic Pyloric stenosis (IHPS) were evaluated with grey-scale and colour Doppler examination. The sonographic findings were categorized as positive IHPS, negative IHPS and equivocal cases. Positive sonographic findings in 21 infants (40%) were confirmed at surgery. Negative sonographic findings in 27 infants (52%) were followed by ward chart reviews.
  
  
  RESULTS
  Sensitivity, Specificity and Accuracy of grey-scale & colour doppler examination for the diagnosis of IHPS were 100%.
  
  
  CONCLUSIONS
  Sonography is the method of choice for the diagnosis of IHPS. Simultaneous grey-scale and colour Doppler examination of pylorus for suspected IHPS is more accurate than simple grey-scale sonography.
