RESUMEN
Objective To investigate the clinical characteristics of fundic gland polyps (FGPs).Methods Data of patients with FGPs diagnosed from January 2005 to May 2010 were collected and retrospectively analyzed.Results A total of 485 patients were found to have FGPs during routine upper endoscopy,accounting for 0.6％ of total upper endoscopy examinations at the same time period.It was most frequently seen in middle aged females.Clinical symptoms included abdominal distention and discomfort ( 182/485,37.5％ ),gastroesophageal reflux symptoms ( 83/485,17.1％ ) and upper abdominal pain (102/485,21.0％ ).51.3％ (249) of the polyps were located at fundus and 168 (34.6％ ) were at corpus,with most of FGPs (62.3％,302/485) were single polyp with broad base (less than 5mm),and 22.7％ (110/485 ) were multiple ones scattering throughout the fundus.The pathology typically showed cystic lesions in the fundic glands,with dysplasia in 8 and intestinal metaplasia in 3,accompanied by duodenal polyps in 11 and gastric cancer in 1.H.pyloriinfection was detected in 47.8 ％ subjects which was similar to the rate of general population (56.1％ ) in the same period (P =0.422 ).In addition,immunohistochemisty staining for adenomatous polyposis coli and cyclooxygenase-2 was performed in 12 patients,which showed all polyps were positive for adenomatous polyposis coli and 9 of them were cyclooxygenase-2 positive.Conclusion FGPs may not be correlate to H.pyloriinfection.It can be accompanied by dysplasia,intestinal metaplasia and duodenal polyps.Pathological and immunohistochemical studies may promote a better understanding and standardized diagnosis and treatment for this disease.
