Double Pylorus, A Case Report / 대한소화기내시경학회지

ABSTRACT

Double pylorus is a rare condition consisting of a double communication between gastric antrum and duodenal bulb; in most cases it is a complication of penetrating ulcer, and sometimes it is a congenital abnormality. The prevalence of this rare anomaly ranges from 0.02% to 0.13%; the male female ratio is about 2 1. A case of double pylorus, in 41 year-old male, was diagnosed by gastrofiberscopy and UGIS. Two ovoid and crescent pits of the pyloric canal divided by smooth thickened septum were observed endoscopically. The upper GI series showed gastroduodenal fistula connecting the leeser curve of distal antrum with the duodenal bulb. The relevant literatures on the subject were reviewed.
