Aim: To identify the incidence of inflammatory lesions in the stomach after bariatric surgery and to correlate it with H. pylori infection.  Methods: This is a prospective study with 216 patients undergoing Roux-en-Y gastric bypass. These patients underwent histopathological endoscopy to detect H. pylori prior to surgery. Positive cases were treated with antibiotics and a proton inhibitor pump followed by endoscopic follow-up in the 6th and 12th month after surgery.  Results: Most patients were female (68.1%), with grade III obesity (92.4%). Preoperative endoscopy revealed gastritis in 96.8%, with H. pylori infection in 40.7% (88\/216). A biopsy was carried out in 151 patients, revealing H. pylori in 60\/151, related to signs of inflammation in 90% (54\/60). In the 6th and 12th month after surgery, the endoscopy and the histopathological exam showed a normal gastric pouch in 84% of patients and the incidence of H. pylori was 11% and 16%, respectively. The presence of inflammation was related to H. pylori infection (p&lt;0,001).  Conclusion: H. pylori has a similar prevalence in both obese patients scheduled to undergo bariatric surgery and the general population. There is a low incidence of it in the 6th and 12th months after surgery, probably owing to its eradication when detected prior to surgery. When inflammatory disease is present in the new gastric reservoir it is directly related to H. pylori infection.<\/jats:p>","DOI":"10.1590\/0102-6720201600s10009","type":"journal-article","created":{"date-parts":[[2016,9,21]],"date-time":"2016-09-21T21:39:52Z","timestamp":1474493992000},"page":"31-34","source":"Crossref","is-referenced-by-count":10,"title":["INFLAMMATORY DISORDERS ASSOCIATED WITH HELICOBACTER PYLORI IN THE ROUX-EN-Y BYPASS GASTRIC POUCH"],"prefix":"10.1590","volume":"29","author":[{"given":"Luiz Claudio Lopes","family":"CHAVES","sequence":"first","affiliation":[{"name":"Federal University of Par\u00e1,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabela Klautau Leite Chaves","family":"BORGES","sequence":"additional","affiliation":[{"name":"Federal University of Par\u00e1,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ma\u00edra Danielle Gomes de","family":"SOUZA","sequence":"additional","affiliation":[{"name":"Federal University of Par\u00e1,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ian Passos","family":"SILVA","sequence":"additional","affiliation":[{"name":"Federal University of Par\u00e1,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lyz Bezerra","family":"SILVA","sequence":"additional","affiliation":[{"name":"Federal University of Par\u00e1,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcelo Alexandre Prado","family":"MAGALH\u00c3ES","sequence":"additional","affiliation":[{"name":"Federal University of Par\u00e1,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allan Herbert Feliz","family":"FONSECA","sequence":"additional","affiliation":[{"name":"Federal University of Par\u00e1,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josemberg Marins","family":"CAMPOS","sequence":"additional","affiliation":[{"name":"Federal University of Par\u00e1,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2016]]},"reference":[{"issue":"4","key":"ref1","doi-asserted-by":"crossref","first-page":"264","DOI":"10.4103\/1319-3767.70610","article-title":"Prevalence of Helicobacter pylori infection in a group of morbidly obese Saudi patients undergoing bariatric surgery a preliminary report","volume":"16","author":"Al-Akwaa AM","year":"2010","journal-title":"Saudi journal of gastroenterology : official journal of the Saudi Gastroenterology Association"},{"issue":"1","key":"ref2","first-page":"38","article-title":"An\u00e1lise dos resultados da endoscopia digestiva alta nos pacientes em pr\u00e9-operat\u00f3rio de cirurgia bari\u00e1trica","volume":"28","author":"Assef MS","year":"2015","journal-title":"ABCD Arquivos Brasileiros de Cirurgia Digestiva"},{"issue":"3","key":"ref3","doi-asserted-by":"crossref","first-page":"647","DOI":"10.3748\/wjg.v20.i3.647","article-title":"Helicobacter pylori infection in obesity and its clinical outcome after bariatric surgery","volume":"20","author":"Carabotti M","year":"2014","journal-title":"World journal of gastroenterology"},{"key":"ref4","first-page":"128","author":"Coelho LGV","year":"2005"},{"issue":"1","key":"ref5","first-page":"33","article-title":"Correla\u00e7\u00e3o entre a endoscopia digestiva alta pr\u00e9 e p\u00f3s-operat\u00f3ria em pacientes submetidos ao bypass gastrojejunal em y-de-roux","volume":"29","author":"Czeczko LEA","year":"2016","journal-title":"ABCD Arquivos Brasileiros de Cirurgia Digestiva"},{"issue":"4","key":"ref6","doi-asserted-by":"crossref","first-page":"249","DOI":"10.1080\/00015458.2013.11680922","article-title":"Value of preoperative esophagogastroduodenoscopy in morbidly obese patients undergoing laparoscopic Roux-en-Y gastric bypass","volume":"113","author":"D'Hondt M","year":"2013","journal-title":"Acta chirurgica Belgica"},{"issue":"1","key":"ref7","doi-asserted-by":"crossref","first-page":"52","DOI":"10.1590\/S0004-28032012000100009","article-title":"Prevalence of upper digestive endoscopy and gastric histopathology findings in morbidly obese patients","volume":"49","author":"Dietz J","year":"2012","journal-title":"Arquivos de gastroenterologia"},{"key":"ref8","series-title":"Conselho Federal de Medicina.
