A CASE OF DOUBLE PYLORUS WITHOUT HELICOBACTER PYLORI INFECTION

Abstract

A 56-year-old female who had been treated by her home doctor with loxoprofen for shoulder pain visited our hospital with a complaint of epigastric pain. The first endoscopic examination showed double pylorus and a large gastric ulcer on the greater curvature of prepyloric region. The second endoscopic examination which was performed four months later revealed a scared gastric ulcer and double pylorus was still present. The case report of double pylorus in which Helicobacter pylori infection is denied by several examinations is very rare. Double pylorus of our case was considered a complication due to nonsteroidal anti-inflammatory drugs.
