Diagnostic imaging of HPS

Purpose: The authors aimed to analyse the value of a diagnostic algorithm in children with hypertrophic pyloric stenosis confirmed at surgery in our hospital. Material and methods: Retrospective review of hospital records of all children operated upon for pyloric stenosis in our hospital from Januar 1995 to December 1999. UGI study was performed with 5-10 ml of diluted barium on Siemens Sireskop 3. Sonographic examinationwas performed in the standard supine and right lateral decubitus position, using a GE Logiq 400 scanner, a 5, 0 MHz convex transducer and a 6, 6 MHz linear transducer. Results: Fourteen infants underwent surgery for hypertrophic pyloric stenosis during the period in question. In all infants the radiologic diagnosis was made on the basis of the uper gastrointestinal series. US was performed in 9 patients ; one case was false negative, the other 8 were positive. Conclusion: Infants with symptoms that clearly suggest pyloric stenosis must be examined by an experienced physician prior to imaging. If the physical examination is negative or equivocal, sonography by an experienced sonographer must be performed. If the US is negative, than the infant should go to UGI. If HPS isn't the primary diagnostic question, it's better to preform UGI first to establish the correct diagnosis.
