Abstract

In the study we analysed ultrasound (US) findings of 73 patients suspected of having hypertrophic pyloric stenosis (HPS). In 44 out of 45 patients with positive US findings, HPS was surgically confirmed. In most of those patients (32, i. e. 72 .7%) , pyloric muscle thickness was 4.4 -6 .2 mm, in 8 (18.2%) it was 3 .6-4.3 m and only in 4 (9 .1%) patients we performed barium study due to doubtful values of pyloric muscle thickness on US (3.3 -3.5 mm); barium study confirmed HPS in one patient and excluded it in two . The pyloric muscle thickness in all patients with HPS was 1.5 time s thicker compared to antral muscle thickness. Ultrasound sensitivity was 89%, and specificity 98%. Based on the results of our study, ultrasound examination of the pylorus has proven to be highly recommendable as a routine first method of choice in the diagnosis of HPS.
