Background:Morbid obesity is a multifactorial disease that increasingly is being treated by
surgery. Aim: To evaluate gastric histopathological changes in obese, and to compare with
patients who underwent gastrojejunal bypass and the jejunal mucosa after the
surgery. Methods:This is an observational study performed at a tertiary public hospital, evaluating
endoscopic biopsies from 36 preoperative patients and 35 postoperative. Results:In the preoperative group, 80.6% had chronic gastritis, which was active in 38.9%
(77.1% and 20.1%, respectively, in the postoperative). The postoperative group had
a significant reduction in H. pylori infection (p=0.0001). A longer length of the
gastric stump and a time since surgery of more than two years were associated with
Helicobacter pylori infection. The jejunal mucosa was normal in 91.4% and showed
slight nonspecific chronic inflammation in 8.6%. Conclusion:There was a reduction in the incidence of Helicobacter pylori infection in the
postoperative group. A longer length of the gastric stump and longer time elapsed
since surgery were associated with Helicobacter pylori infection. The jejunal
mucosa was considered normal in an absolute majority of patients.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
