The Double Pylorus (DP) is an unusual finding in the gastros­copy where the gastric antrum and the duodenal bulb is con­nected to by two holes separated by a septum or bridge. Its etiology may be congenital or acquired the latter being the most common form as a complication of peptic ulcer disease (EUP). Most fistulas are located on the lesser curvature of the gastric antrum. There have been described three theories in the formation of acquired DP. It may present with epigastric pain, dyspepsia or gastrointestinal bleeding but sometimes it is an endoscopic or radiological incidental finding. We present a patient who presents with upper gastrointestinal bleedings­ymptoms in whom a gastroscopy where performed with this unusual finding which was confirmed by radiological study. In general the prognosis is favorable.

Palabras clave : Pylorus; duodenal bulb; double pylorus; gas­troscopy.
