Abstract. Duodenal nodules are an uncommon endoscopic finding generally thought to indicate duodenal inflammation. This study examines the incidence and histologic correlates of multiple and single duodenal nodules in 2,966 consecutive male patients who underwent esophagogastroduodenoscopy during the past five years.
