Abstract		In the study, we analysed ultrasound (US) findings of 68 patients suspected of having hypertrophic pyloric stenosis (HPS). In 44 out of 45 patients with positive US fingins, HPS was surgically confirmed. In 82.6% patients (38 pts), pyloric muscle thickness was 5-7 mm, in 10.9% (5 pts), it was 3-5 mm, and only in 6.4% patients (3 pts), we performed barium study due to doubtful values of pyloric muscle thickness (3.0-3.4 mm) detected by US; barium study confirmed HPS in one patient and excluded in two patients. The pyloric muscle thickness in all patients with HPS was at least 1.5 times thicker comparing to antral muscle thickness. Ultrasound sensitivity was 98%, and specificity 92%. Based on the results of our study, ultrasound examination of the pylorus has proved to be highly recommendable as a routine method of first choice in the diagnosis of HPS.
Summary		V raziskavi smo analizirali izvide ultrazvočne preiskave 8 bolnikov, pri katerih smo sumili, da so oboleli za hipertrofično pilorično stenozo (HPS). Od 45 bolnikov s pozitivnim ultrazvočnim izvidom je bila HPS tudi po kirurškem zdravljenju potrjena. Dolžina pilorične mišice je bila pri 82,6% bolnikov (38 bolnikov) 5-7 mm, pri 10,9% bolnikov (5 bolnikov) pa je bila dolžina te mišice 3-5 mm in pri samo 6,4% bolnikov (3 bolniki) je bilo potrebno tudi rentgensko slikanje z barijem zaradi z ultrazvočno preiskavo ugotovljene sumljive debeline pilorične mišice (3,0-3,4 mm). Rentgensko slikanje z barijem je potrdilo diagnozo HPS pri enem bolniku, pri dveh pa je to diagnozo ovrglo. Debelina pilorične mišice je bila pri vseh bolnikih z ugotovljeno HPS 1,5 krat večja kot debelina antralne mišice. Občutljivost ultrazvoka je bil 98%, specifičnost pa 92%. Na osnovi rezultatov naše raziskave ugotavljamo, da sodi ultrazvočna preiskava pilorusa med najbolj priporočljive diagnostične metode za ugotavljanje HPS.
