Duminda Bernard Suraweera, Jaimin Amin, Armine Baltayan, Richard Hu


Brunner’s gland hyperplasia, sometimes referred to as Brunneroma or Brunner’s hamartoma, is a benign lesion arising from the duodenum. We report an unusual case of Brunner’s gland hyperplasia leading to severe gastric outlet obstruction requiring surgical intervention. A literature review of previous Brunnner’s gland hyperplasia cases leading to gastric outlet obstruction and the treatment strategies pursued in such cases suggest that size and pedunculation were important characteristics in determining amenability for endoscopic treatment.
