A CASE OF BRUNNERS GLAND HAMARTOMA PRESENTING AS GASTRIC OUTLET OBSTRUCTION: SURGICAL APPROACH AND LITERATURE REVIEW

Brunners gland hamartoma, also known as Brunneroma, is a rare, non-cancerous tumor that represents about 5–10% of benign duodenal growths, with an incidence of less than 0.01%. Most cases remain silent, causing no symptoms, but in some instances, they can lead to duodenal obstruction, upper gastrointestinal bleeding, or, more rarely, complications such as biliary fistulation, cholestatic jaundice, or intussusception. Diagnosis is primarily based on imaging techniques and upper gastrointestinal endoscopy. When these hamartomas grow large and cause symptoms, treatment typically involves surgical or endoscopic removal. Here, we present the case of a 50-year-old man with no known medical history who developed symptoms of gastric outlet obstruction. He was diagnosed with a sizable Brunners gland hamartoma and successfully treated with surgery.
