title: Double pylorus or antro-bulbar fistula.
abstract: A patient suffering from rheumatoid arthritis and a gastric ulcer was found endoscopically to have a double pylorus. One year later the two apertures were found to be fused and appeared endoscopically like a deformed pylorus. We suggest that this lesion, which is usually acquired but may sometimes be congenital, would be better called antro-bulbar fistula.
