Core Tip
Core tip: Although ampullary tumors are relatively rare, the rapid development of, and advances in, endoscopy and imaging techniques have profoundly increased their discovery rate. Despite the increasing numbers of published studies, the etiology for ampullary tumors is incompletely defined. This is the first study to evaluate the impact of metabolic syndromes on ampullary tumors patients.
