The double pylorus is a fistulous communication between the gastric antrum and duodenal bulb, usually extending from the lesser curvature of the stomach to superior aspect of the duodenal bulb, and seperated by septum or bridge normal mucosa.
Although
its incidence is rare, reports concerning double pylorus are increasing with recent development of upper gastrointestinal endoscopy and more awareness of this abnormality.
We recently experienced two cases of double pylorus; an aquired one in 72-year old male who had an another opening with healing ulcer at the superior aspect of the original pyloric channel, central erosion with clubbing and fusion of mucosal
folds
at
the greater curvature of the lower body and a 3×4cm sized ulcer at the lesser curvature of the lower body, and the other congenital one in 53-year old male who had an another opening at the superior aspect of the original pyloric channel with
histologically intact muscularis mucosa in the pyloric septum with no evidence of chronic peptic ulcer scarring.
We report here two cases of double pylorus, one-acquired, and the other-congenital, with a review of the literature.
