title: Sporadic fundic gland polyps: clinico-pathologic features and associated diseases.
abstract: BACKGROUND
  Fundic gland polyps have been described either in association with genetic polyposis syndromes of the colon, or in a sporadic form. In the first case they are diagnosed during family screening in asymptomatic subjects, while sporadic FGP patients often complain of upper gastrointestinal symptoms. So far, no great attention has been paid to the clinical presentation of these patients, so we undertook a clinico-pathologic study to further delineate: the clinical presentation at 1st examination; the associated gastrointestinal conditions; a possible role of omeprazole; Helicobacter pylori (H. pylori) colonization, the presence of intestinal metaplasia and dysplasia.
  
  
  METHODS
  We followed-up for a 9-year period with endoscopies a case series of 70 patients with sporadic FGPs, recording endoscopic data, symptoms, associated gastrointestinal conditions, previous therapies, histopathological findings.
  
  
  RESULTS
  The prevalence of the present series was 0.36%. The patient prevalence and number of polyps by age classes rose in women (maximum value in perimenopausal age), while was constant in males. We observed a frequent association between FGPs and esophageal conditions (34%), namely hiatus hernia-reflux esophagitis, significantly higher than in our endoscopic population (15%). Five patients had an isolated colonic adenoma. Only one patient had received long term omeprazole therapy. H. pylori was negative in all 70 FGPs, and in 15 samples of antral mucosa. No metaplastic or dysplastic lesions were seen.
  
  
  CONCLUSIONS
  Sporadic FGP patients frequently complain of epigastric pain, burning, dyspepsia, probably related to the frequently associated esophageal pathology, namely reflux esophagitis-hiatus hernia (34%). Prevalence of FGPs and polyps number are linked to female sex (maximum rise for both values in perimenopausal age). No link with omeprazole therapy was seen. FGPs patients appear to be protected from H. pylori colonization and ultimately from the development of intestinal metaplasia-dysplasia-gastric cancer. Nonetheless, they are apparently more prone to colonic adenomas. So, every sporadic FGP patient should undergo colonic surveillance.
