Gastric polyps: a retrospective analysis of 26, digestive endoscopies

Two percent of polyps were adenocarcinomas. A total of Gastric polyps classification is based on its histological features, and based on that, we can differentiate two important groups: Hyperplastic polyps of the stomach: In our series, There are no specific symptoms related to the presence of gastric polyps.

Yamada’s classification Gllandulas were classified macroscopically according to Yamada’s classification Type IV polyps are pedunculated and elevated Figure 3. The clinical findings associated with gastric polyps depend on the polyp size and location 3. The raised erosion and mucosa in mosaic in the body are suggestive but not specific to the infection.

The significance of possible associations between discrete variables was evaluated by c 2 test of Pearson. J Clin Pathol ; We established that treatments over 3 months were considered as long term treatment with PPI and therefore we gpandulas exclude that a larger interval might have found a significant association.

Erosion or ulceration of the polyp surface may cause occult bleeding and anemia, and upper gastrointestinal bleeding may occur if there are large lesions. Symptoms such as pain, nausea and vomiting were frequent in most patients and could not be attributed solely to the polyp found, since there were frequently other endoscopic alterations implying other gastroenterological diseases Histopathological classification and malignant chance in gastric polyps.

The second group is the most common 3and among them we may find several subtypes such as hyperplastic or fundic glands polyps. The description of different patterns of erythema in gastric body under magnification of images revived interest in identifying these patterns by standard endoscopy.

BURT 1 studied patients with FGP and emphasizes that they may be a trivial finding or evidence of a significant underlying inherited polyposis syndrome and colonoscopy shoud be done.

We found no significant association between the histopathological type of lesions and the use of proton pump inhibitor.

The main exclusion criteria were the use of drugs, HP pre-treatment and glansulas entities that could affect results. Precursors of gastric cancer. One hundred and fifty three patients in a series of 26, consecutive upper digestive endoscopies done over a 5-year period, being that each patient had only one examination were analyzed and their histological and Yamada classification, as well as their location, size, histopathological findings and treatment studied.

Large series of polypectomies published in 21st century in different countries, showed diverse incidents of histopathological findings.

Ann Intern Med ; On the negative group the normal appearance of the mucosa was The location of the polyps was based on endoscopic findings, glandulsa the gastric areas were divided into antrum, body and fundus. Continuous variables were described using mean and standard deviation SDdiscrete ones using percentages. Histologic features, presence of associated chronic gastritis and infection by H.

The relative prevalence of different subtypes found in series with patients from nearer geographical areas resemble our funeicas.
