Endoscopic polypectomy of a giant Brunner’s gland hamartoma using a detachable loop

Brunner's gland hamartoma (BGH) is an uncommon, benign tumour of the duodenum that can cause bleeding in the digestive tract or blockage of the upper digestive tract. Until now, surgery was always the treatment used, but advances in endoscopic techniques now make it possible to consider endoscopic resection. We here describe the case of giant Brunner's gland hamartoma of typically hypodense appearance, which was discovered fortuitously and successfully removed by endoscopic polypectomy using a diathermic snare with a detachable loop. We describe the specific features of a hamartoma, despite the usual use of the term "Brunner's gland adenoma".
