ABSTRACT

Retrospective studies of duodenal polyps have shown a prevalence of 0.3-4.6% in patients referred to upper gastrointestinal endoscopy, and histologic classification have been inconsistent. A prospective consecutive study was carried out in 3,871 patients referred to diagnostic endoscopy, Sixteen patients had polyps in the first part of duodenum, for a prevalence 0.41%(0.28-0.53%, 95% confidence interval). Fourteen polyps were either inflammatory(thirteen polyps) or ectopic gastric mucosa(one polyp). Two hyperplasitc polyps were founded. All polyps were benign and sessile, and most of polyps(75%) were solitary.
