Abstract

Hypertrophic pyloric stenosis is a disease that occurs in the second week of life, of unknown origin, which consists of the narrowing of the pylorus due to concentric muscular hypertrophy, causing gastric outlet obstruction with progressive vomiting that leads to malnutrition, dehydration, and serious metabolic disorders. Hypertrophic pyloric stenosis is exceedingly rare in newborns and is rarely reported in the literature. This report is of a premature newborn, low birth weight with hypertrophic pyloric stenosis. The patient presented with vomiting milk at 4 days of age, epigastric distension and dilated gastric shadow on the abdominal radiograph. The child was treated in the direction of gastroesophageal reflux but the disease did not progress, the child still vomited milk fluid. Gastrointestinal circulation with contrast showed only dilated stomach. Re-ultrasound on day 10 showed thickened pylorus. The patient underwent pyloromyotomy with open surgery. Postoperative progress, the patient improved without vomiting milk, discharged after 1 week.
