Acute duodenal obstruction after hemorrhaging of a duodenal duplication cyst

Duodenal duplication cysts are relatively rare congenital anomalies that occur most often in infants and children. We report a case of a 13-year-old boy who presented with duodenal obstruction caused by bleeding of a duodenal duplication cyst. Operative findings and hispathological examination confirmed the diagnosis. We treated him with subtotal excision of the duodenal duplication cyst and mucosal stripping and ablation of the remaining mucosa
