Assessment of Duodenal Adenomas and Strategies for Curative Therapy

Background: The increasing incidence of duodenal neoplasm has underlined different methods of resection depending on the clinical presentation, endoscopic features and histopathology. In this comprehensive review, we systematically describe the current knowledge concerning the diagnosis and management of duodenal adenomas (DAs) and discuss data considering all possible therapeutic approaches.Summary: Among a variety of duodenal lesions, including neuroendocrine tumors and gastrointestinal stromal tumors, DAs present precancerous lesions of the duodenal papilla or non-ampullary region necessitating removal. DAs can occur sporadically (SDA) as rare lesions or relatively common in polyposis syndromes. The endoscopic resections of DA are associated with an increased degree of complexity due to distinctive anatomical properties of the duodenal wall, luminal diameter and the presence of ampulla with pancreatic and biliary drainage. The endoscopic techniques including cold snare polypectomy (CSP), endoscopic mucosal resection (EMR), and argon plasma coagulation ablation are suggested to be less invasive than surgical treatment, associated with shorter hospital stay and lower cost. According to the current clinical practice, surgery has been accepted as standard therapeutic approach in familial adenomatous polyposis patients with severe polyposis or DA not amenable to endoscopic resection.Key Messages: The strategy for endoscopic resection of DAs depends on the lesion size, morpholog...
