title: A case of duodenal duplication cyst manifested by duodenal polyp.
abstract: Duodenal duplication cyst is a rare anomaly, totaling only 4% to 12% of gastrointestinal duplications, and is usually encountered during infancy or in early childhood. Most are commonly located posterior to the first or second portion of the duodenum. Presenting signs and symptoms include vomiting, decreased oral intake, periumbilical tenderness, abdominal distention, obstructive jaundice, acute pancreatitis, and gastrointestinal bleeding. The traditional treatment of a duodenal duplication cyst has been complete surgical resection, but very few cases of endoscopic treatment have been reported in the literature. Here, we report a case of duodenal duplication cyst that was manifested by a duodenal polyp.
