Endoscopic Resection of a Large Ampullary Adenoma

Abstract: An ampullary adenoma is a glandular dysplastic lesion arising from the duodenal papilla and is a pre-cancerous lesion. It is either sporadic or associated with familial adenomatous polyposis syndrome. Treatment options for ampullary adenoma include a pancreaticoduodenectomy, surgical local excision, or endoscopic ampullectomy. An endoscopic approach has been shown to be an effective treatment for these lesions while avoiding the risks that come with more invasive surgical procedures. In this report, we discuss a case of a large ampullary adenoma with low grade dysplasia treated successfully with endoscopic ampullectomy. Key words: Ampullary adenoma, endoscopic ampullectomy.
