Abstract
A case of acquired double pylorus complicated with systemic lupus erythematosus is described. The patient is a 50-year-old female. Upper gastrointestinal series and fiber-scopic examination by means of so-called U-turn technique with a small caliber panendo-scope in the duodenal cap confirmed a pylorus consisting of two opennings deviled by a septum. Double pylorus in this patient appears to be due to a pyloroduodenal fistula caused by penetration of a prepyloric ulcer into the duodenum.
