RESUMO
Objective To investigate the clinical features,diagnostic modalities and treatment of duodenal Brunner′gland adenoma(BGA).Methods Fifteen patients with duodenal BGA were evaluated base on clinical presentations,the results of serologic test,barium meal examination,gastroscopy and endoscopic ultrasonography(EUS)as well as treatment.The post-operative histological results were compared with pre-operation EUS findings.Results Eight out of 15 patients with duodenal BGA had presentations,including duodenal ulcer(4 patients),upper gastrointestinal hemorrhage (4 patients). The serologic tests of all patients were within the normal limits.Six patients underwent barium meal examination and 13 patients received gastroscopy.Seven patients underwent surgical treatment and 8 patients received endoscopic resection.The post-operative histological results were compatible with the pre-operative EUS findings.Conclusions Duodenal BGA is a benign tumor.EUS was helpful in making the diagnosis and determination of treatment methods(surgical operation or endoscopic resection).
