title: Acquired double pylorus, due to penetrating gastric ulcer, presenting with melena.
abstract: Acquired double pylorus (DP) is an uncommon condition consisting of two communicating channels between the gastric antrum and the first part of duodedum. Little is known about the origin of DP. As there is no specific gastrointestinal symptom due to DP, most often it is diagnosed by gastroscopy while performing for other indicationsFew data are also known about the clinical course of DP. In the patients with peptic ulcer symptoms, the pyloroplasty-like drainage effect, improving gastric emptying after the estabilishment of the fistula, could relieve these symptoms. This represents an unresolved issues about the necessity of repeating endoscopy to document in the patients with DP its final outcome, as the risk of ulcer recurrence. We describe a case of a 76-years-old woman admitted to our department for hyposideremic anemia associated to a recent history of melena.
