Abstract
Background and 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.

Material and 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 6307
(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%).
