title: Gastric polyps: analysis of endoscopic and histological features in our center.
abstract: OBJECTIVE
  the prevalence of gastric polyps in esophagogastroduodenoscopies (EGDs) ranges between 0.33 and 6.35%. The relative frequency of histological subspecies varies widely among published series. The objective is to describe the endoscopic and histological characteristics of the polypoid lesions, and to study possible associations.
  
  
  METHODS
  we retrospectively revised the EGDs done in our center in 2009. Demographic, endoscopic and histological data were gathered. We proceeded to a descriptive analysis and studied possible associations.
  
  
  RESULTS
  gastric polypoid lesions were found in 269 of the 6,307 (4.2%) reviewed EGDs, 61% were found in women. Mean age was 64.93 years (SD: ±15.23). A single polyp was found in 186 patients (69.1%), over 10 lesions appeared in 31 (11.5%). An estimated size of ≤ 3 mm was found in 108 lesions (37.2%) and greater than 10 mm in 52 cases (17.9%). Most lesions were sessile (90.8%). The location of 34.8% was the gastric antrum, 39.3% were found in the gastric body and 25.9% were in the fundus. Chronic gastritis was confirmed in 53.5% of the patients and 46.5% had received protom pump inhibitors (PPIs). Histopathological diagnosis was: hyperplastic polyps 50.9%, fundic gland polyps 7.4%, adenomas 3%, adenocarcinomas 1.9% and normal mucosa 29.7%. We found no significant association between the histopathological type of lesions and the use of proton pump inhibitor.
  
  
  CONCLUSIONS
  we found polypoid lesions in 4.2% of the EGDs. The most frequent histopathological findings were hyperplastic polyps (50.9%), followed by fundic gland polyps (7.4%), adenomas (3%), and adenocarcinomas (1.9%).
