Sonographic Diagnosis of Infantile Hypertrophic Pyloric stenosis- Use of
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 songraphic 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%.
Conclusion: Sonography is the method of choice for the diagnosis of IHPS. Simultaneous greyscale
and colour Doppler examination of pylorus for suspected IHPS is more accurate than
simple grey-scale sonography.
Key words: Grey-scale Sonography, Colour Doppler examination, Infantile Hypertrophic Pyloric
stenosis, experienced radiologists.
