Prepyloric gastric antral web: a puzzling epidemic.

M J Bell, J L Ternberg, J P Keating

    Journal of Pediatric Surgery
    |June 1, 1978
    PubMed
    Summary

    Antral webs, a rare cause of gastric outlet obstruction in children, present with vomiting. Radiography is key for diagnosis, with pyloroplasty often required for treatment.

    Area of Science:

    • Pediatric Surgery
    • Gastroenterology
    • Radiology

    Background:

    • Antral webs and diaphragms are rare causes of gastric outlet obstruction in pediatric patients.
    • Gastric outlet obstruction can significantly impact infant and child health.

    Purpose of the Study:

    • To describe the clinical presentation, radiographic findings, and management of antral webs in children.
    • To highlight the diagnostic clues for antral webs on radiographic imaging.

    Main Methods:

    • Retrospective review of 28 pediatric cases diagnosed with antral webs over 26 months.
    • Analysis of presenting symptoms, radiographic findings, and treatment outcomes.

    Main Results:

    • Nonbilious, projectile vomiting was the primary symptom in infants (<6 months).
    • Older children presented with pain, vomiting, and postprandial fullness.
    • Radiography revealed a characteristic wirelike transverse septum proximal to the pylorus, with poor antral filling as an early sign.
    • Pyloroplasty was performed in 20 patients, often after failed medical management.
    • Congenital abnormalities were noted in 28% of patients.

    Conclusions:

    • Antral webs are a treatable cause of gastric outlet obstruction in children.
    • Radiographic findings, particularly poor antral filling and a transverse septum, are crucial for diagnosis.
    • Surgical intervention (pyloroplasty) is frequently necessary for successful management.
