چکیده

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. Racional: A obesidade mórbida é doença multifatorial cujo tratamento cirúrgico é cada vez mais indicado. Objetivo: Avaliar alterações histopatológicas gástricas em obesos e comparar com os submetidos à bypass gastrojejunal e a mucosa jejunal após a operação. Método: Estudo observacional realizado em hospital público terciário avaliando biópsias endoscópicas de 36 pacientes no pré-operatório e 35 no pós-operatório. Resultados: No pré-operatório 80,6% apresentaram gastrite crônica, 38,9% em atividade (77,1% e 20,1%, respectivamente, no pós-operatório). O grupo pós-operatório apresentou diminuição significativa na infecção por Helicobacter pylory (p=0,0001). Maior comprimento do coto gástrico e tempo de operação superior a dois anos associaram-se a infecção por Helicobacter pylori. A mucosa jejunal foi normal em 91,4% e apresentava leve inflamação crônica inespecífica em 8,6%. Conclusão: Houve diminuição da infecção por Helicobacter pylori após a operação. Maior comprimento do coto gástrico e do tempo de operação associaram-se à infecção por Helicobacter pylori. A mucosa jejunal foi considerada normal na maioria absoluta dos pacientes do grupo pós-operatório.
