Gastric outlet obstruction (GOO) is common in early infancy but is rare when hypertrophic pyloric stenosis is excluded. Primary acquired GOO, or Jodhpur disease, primarily affects males aged 3-6 years, present with nonbilious vomiting. Diagnosis involves imaging, and treatment typically includes surgical intervention.

A 6-month-old Filipino female presented with abdominal distention, postprandial vomiting, and fever. After conservative management and exploratory laparotomy, she improved post-surgery but experienced recurrence of symptoms. Follow-up showed her active and symptom-free, though she left against medical advice before completing antibiotics.

Primary acquired gastric outlet obstruction (GOO), or Jodhpur disease, occurs in 1 in 100,000 children, primarily affecting males aged 1 month to 6 years. Its unclear etiology includes dietary factors and nitric oxide synthase deficiency. Diagnosis involves imaging, and surgical intervention is typically necessary, with effective treatments including pyloroplasty and pneumatic dilation.

This case underscores the importance of clinical suspicion for primary acquired GOO in young children and advocates for prompt diagnostic imaging and timely surgical intervention to prevent complications such as malnutrition and growth retardation.
