[Hypertrophic Pyloric Stenosis - Five-Year Retrospective Analysis]

Although the etiology of the disease has not yet been fully clarified in the 21st century, clinical significance of the disease is huge because it is frequent in the neonatal period compared with other diseases. Today, owing to advanced diagnostic possibilities, hypertrophic pyloric stenosis is easily distinguished from other differential diagnoses that are manifested by vomiting as the main symptom. At Department of Pediatric Surgery, Zagreb Children’s Hospital, efforts have been invested to successfully manage this and a number of other conditions that affect newborns. We retrospectively analyzed data on 40 hospitalized children retrieved from the hospital information system for the 2010-2015 period and present them as a basis for the respective algorithms and future research. Reviewing a range of parameters, we have come to some concrete conclusions. On average, the disease started manifesting on 28th day after birth; 63% of the children developed metabolic alkalosis. Thickness of the muscle wall verified by ultrasound ranged from 3.1 mm to 7 mm. Surgery was performed seven days after hospitalization and correction of metabolic condition. The average duration of surgery was 48 minutes. The mean length of hospital stay was 11.64 days, of which 2 days in the intensive care unit. Complications occurred in two patients.
