Abstract
A 31-year-old woman was diagnosed with duodenal grade 1 follicular lymphoma. The patient underwent radiotherapy and on surveillance enteroscopy, the lymphoma was persistently identified in the duodenum and jejunum. Endoscopic clips were used as fiducials to better localize the tumor during radiotherapy. Endoscopic clips are increasingly used as tumor localization tools because of their favorable risk-benefit ratio. In our case, endoscopic clipping was necessary to properly localize the tumor after prior treatment failure, and the patient now has no evidence of disease. Larger studies are needed to demonstrate the efficacy of clips in tumor localization and improved disease-related morbidity.
