LOPEZ-CASILLAS, Nelson  y  LOPEZ-GAXIOLA, Ramón. Double pylorus: From the everything to the extraordinary; case report and literature review. Rev Chil Cir [online]. 2017, vol.69, n.4, pp.341-344. ISSN 0718-4026.

Background: The double pylorus is an extremely rare endoscopic finding, being more frequent in patients suffering from peptic ulcer disease. It corresponds to an abnormal communication between the gastric antrum and the duodenal bulb, which may require surgical treatment. Clinical case: A 86-year-old woman with a history of type 2 diabetes mellitus, hypertension and chronic NSAID intake, a carrier of long-term peptic acid disease with poor response to medical management with H2 blockers. This presents digestive tube bleeding for 5 days characterized by hematemesis and melena, as well as heartburn, nausea, without weight loss, reason why high digestive endoscopy is performed, which reports as findings: active chronic erosive gastritis secondary to NSAIDs and associated with Helicobacter pylori, as well as acquired double pylorus secondary to peptic acid disease, without evidence of tumors or other associated lesions. Eradication scheme begins for H. pylori with amoxicillin and clarithromycin for 14 days, associated with a proton pump inhibitor for 6-8 weeks with good response to medical management. Discussion: The acquired double pylorus is a rare complication of peptic ulcer disease that can be associated with other diseases, NSAIDs and colonization by H. pylori, therefore the appropriate treatment will consist in the correction of these factors.
