A CASE OF DOUBLE PYLORUS

Abstract

A 70-year-old male visited to our hospital complaning of epigastralgia. He had been treated a neuralgia of the lower extremity with a large amount of analgesics. The initial endoscopic examination revealed a deep gastric ulcer on the posterior wall of the prepyloric region. Medical treatment brought abous a relief of symptom, but no improvement in endoscopic findings of gastric ulcer after 3 months. Follow-up endoscopy after 8 months revealed that this lesion had penetrated into the duodenal bulb forming double pylorus. X-ray examination of upper gastrointestinal tract also revealed a gastro-duodenal fistula communicating between the posterior wall of the pyloric region and duodenal bulb. He had been followed up endoscopically for these three years and no change in form of the double pylorus.
