Brunner’s glands, also called duodenal glands, are found in the submucosa of the duodenum, typically in the duodenal bulb and in the second portion of the duodenum proximal to the sphincter of Oddi. Furthermore, in response to the presence of acid in the duodenum, these glands secrete pepsinogen and urogastrone, which inhibit gastric acid secretion. It may be an incidental finding during an investigation but can also present acutely with haemorrhage or obstruction, requiring endoscopic or surgical resection. We present a series of 25 cases of Brunner's gland cyst, the largest case series to date. Brunner’s gland hyperplasia is usually asymptomatic, which means that it may show no symptoms or some symptoms such as abdominal pain, upper gastrointestinal bleeding, and may be associated with chronic pancreatitis. Where the diameter of focal hyperplasia is less than 1 cm, the term Brunner gland hyperplasia is used.. Etiology remains obscure. Endoscopic removal is recommended to prevent complications due to gastrointestinal bleeding.

Brunner's glands (or duodenal glands) are compound tubular submucosal glands found in that portion of the duodenum which is above the hepatopancreatic sphincter (i.e sphincter of Oddi). An individual gland may secrete its mucus directly into the intestine, or its secreting tubes or ducts could join up with other glands in the gut wall.
