Diagnostic Accuracy of Gray Scale and Colour Doppler Ultrasound in the Diagnosis of Infan-Tile Hypertrophic Pyloric Stenosis

Objective: To determine the diagnostic accuracy of gray scale and color Doppler ultrasound in infantile hypertrophic pyloric stenosis.Material and Method: 45 patients with clinical suspicion of infantile hypertrophic pyloric stenosis were evaluated with gray scale and color Doppler ultrasound. According to the measuring parameter using gray scale and color Doppler the finding were categorized into positive and negative. Positive findings were confirmed in surgery which were present in 18 infants (40%). Negative finding were present in 27 infants (60%) which were confirmed by means of follow-up.Result: The diagnostic accuracy, sensitivity, specificity of gray scale ultrasound in diagnosing infantile hypertrophic pyloric stenosis is 100%.Conclusion: Ultrasound is the method of choice in the diagnosis of infantile hypertrophic pyloric stenosis. The use of the color Doppler aids in diagnosis of IHPS than using the gray scale alone.
