SICCHA-SINTI, Christian et al. Prevalence of histological types of gastric polyps in adult patients from a public hospital in Lima-Peru (2007 - 2016). Rev. gastroenterol. Perú [online]. 2019, vol.39, n.1, pp.12-20. ISSN 1022-5129.

Objectives: Establish the prevalence of gastric polyps detected by upper gastrointestinal endoscopy in patients older than 18 years old during the period from 2007 - 2016 in Cayetano Heredia Hospital. Materials and methods: Retrospective cross- sectional study, performed with data from the gastric biopsies reports of patients that have undergone upper gastrointestinal endoscopy between January 2007 and July 2016. Demographic data, endoscopic characteristics of the polyps and associated histological changes of the surrounding gastric mucosa were evaluated, which were subjected to statistical analysis using STATA v14.2. Results: In a population of 16 552 endoscopies, 407 gastric polyps biopsies were found. These results give a prevalence of 2.5% .Gastric polyps were detected predominantly in women (62.38%). The median age was 61 years (52-71 years). The most frequent histological type was the fundic gland polyp (FGP) (44.85%), followed by the hyperplastic (38.48%) and adenomatous (15.23%) polyp. The most frequent location was in the fundus / corpus (48.65%, p = 0.001). The presence of Hp was detected in 30.6% of the biopsies with polyps. Conclusion: The prevalence of gastric polyps is similar to other regions of the world; PGF and hyperplastic are the most frequent. Adenomatous polyps showed a greater relationship with and metaplasia and dysplasia.
