Congenital hypertrophic pyloric stenosis of 21 days infant

Abstract

Hypertrophic Pyloric Stenosis (HPS) is a condition that occurs in infants with an abnormally thickened pyloric stomach, presented with a symptom of projectile vomiting. The cause of HPS is still unclear. However, it may occur due to multiple factors, including racial, environmental, and genetic factors, with the incidence of one to two out of 1000 live births. We reported a Hypertrophic Pyloric Stenosis (HPS) case in a 21-day-old baby girl (baby I) with projectile vomiting and yellowish diarrhea about six days before admission, which was recorded to be more than five times a day. The patient was hospitalized at Anwar Medika Hospital for five days before being referred to dr. Soetomo Hospital, Surabaya, and a pyloromyotomy were performed. Physical examination and radiological investigations (plain radiographs, Upper Gastrointestinal (UGI), and ultrasonography (USG)) supported the diagnosis of HPS. Ramstedt pyloromyotomy procedure had been conducted with a diagnosis of post-pyloromyotomy hypertrophic pyloric stenosis.
