An Infant with Antral Dysmotility

Abstract

Antral dysmutility is a disease entity which was first described by W. J. Byrne in 1981. Its main symptom is chronic vomiting in infancy and unique radiographic findings in the antrum on uppergastrointestinal series. Normal or elevated lower esophageal sphincter pressure and absence of reflux with one hour intraesophageal pH monitoring are reported to be characteristic findings. Recently, we experienced a male infant of four and half month old. By upper gastrointestinal radiographic, endoscopic and esophageal motility studies, he was diagnosed to have antral dysmotility and was treated conservatively with cure. He seems to be the first case of antral dysmotility reported in the Japanese literature.
