Gastroesophageal reflux is considered potential factor that may result in damage to the esophageal mucosa and this subject is quite controversial in the literature. Aim: To evaluate patients who underwent to Roux-en-Y gastrojejunal bypass correlating epidemiologic and endoscopic findings in pre and postoperative periods. Method: A retrospective, paired study which evaluated 110 patients. Inclusion criteria were formal indication for bariatric surgery and patients with pre and postoperative endoscopy. Exclusion criteria were previous bariatric surgery, patients subjected to other types of bariatric surgery and those who had no pre or postoperative upper digestive endoscopy. The epidemiological variables were: sex, age, body mass index, type 2 diabetes mellitus or impaired glucose tolerance, and preoperative dyslipidemia. Results: The preoperative upper endoscopy was normal in 26.4% of the patients. Among endoscopic alterations, the hiatus hernia was the most prevalent followed by non-erosive gastritis. The postoperative upper endoscopy was normal in 40.9% and stenosis was the most prevalent followed by marginal ulcer. Correlation on pre and postoperative endoscopies, was found 100% reduction of hiatal hernias and 88% of esophagitis. There was no statistical significance in relationship to anastomotic stenosis with preoperative other variables. Conclusions . There was significant decrease in postoperative hiatus hernia, erosive esophagitis, non-erosive esophagitis, erosive gastritis and non-erosive gastritis with the operation. Stenosis of the gastrojejunostomy anastomosis was the most prevalent postoperative complication with no correlation with preoperative variables.<\/jats:p>","DOI":"10.1590\/0102-6720201600010009","type":"journal-article","created":{"date-parts":[[2016,4,20]],"date-time":"2016-04-20T18:23:28Z","timestamp":1461176608000},"page":"33-37","source":"Crossref","is-referenced-by-count":15,"title":["CORRELATION BETWEEN PRE AND POSTOPERATIVE UPPER DIGESTIVE ENDOSCOPY IN PATIENTS WHO UNDERWENT ROUX-EN-Y GASTROJEJUNAL BYPASS"],"prefix":"10.1590","volume":"29","author":[{"given":"Leticia Elizabeth Augustin","family":"CZECZKO","sequence":"first","affiliation":[{"name":"Evangelic Faculty of Paran\u00e1, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manoela Aguiar","family":"CRUZ","sequence":"additional","affiliation":[{"name":"Evangelic Faculty of Paran\u00e1, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fl\u00e1via Caroline","family":"KLOSTERMANN","sequence":"additional","affiliation":[{"name":"Evangelic Faculty of Paran\u00e1, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolau Gregori","family":"CZECZKO","sequence":"additional","affiliation":[{"name":"Evangelic Faculty of Paran\u00e1, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulo Afonso Nunes","family":"NASSIF","sequence":"additional","affiliation":[{"name":"Evangelic Faculty of Paran\u00e1, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandre Eduardo Augusto","family":"CZECZKO","sequence":"additional","affiliation":[{"name":"Evangelic Faculty of Paran\u00e1, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","reference":[{"key":"ref1","article-title":"Endoscopia em cirurgia bari\u00e1trica","author":"Campos JM","year":"2008","journal-title":"Projeto Diretrizes"},{"issue":"2","key":"ref2","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1001\/jama.289.2.187","article-title":"Years of life lost due to obesity","volume":"289","author":"Fontaine KR","year":"2003","journal-title":"JAMA"},{"issue":"1","key":"ref3","first-page":"61","article-title":"Perda Ponderal ap\u00f3s Gastroplastia em Y de Roux e Import\u00e2ncia do Acompanhamento Nutricional - Uma Revis\u00e3o de Literatura","volume":"22","author":"Rocha QDS","year":"2011","journal-title":"Com Ci\u00eancias Sa\u00fade"},{"issue":"2","key":"ref4","doi-asserted-by":"crossref","first-page":"229","DOI":"10.1016\/j.giec.2011.02.010","article-title":"Presurgical evaluation and postoperative care for the bariatric patient","volume":"21","author":"Tariq N","year":"2011","journal-title":"Gastroenterol Clin North Am"},{"issue":"1","key":"ref5","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.gie.2008.01.028","article-title":"Role of endoscopy in the bariatric surgery patient - Guideline da Sociedade Americana de Endoscopia Gastrointestinal","volume":"68","author":"Anderson MA","year":"2008","journal-title":"Gastrointest Endosc"},{"issue":"2","key":"ref6","first-page":"164","article-title":"Pre-operative endoscopy in bariatric surgery patients","volume":"61","author":"Bahra G","year":"2012","journal-title":"Gut"},{"issue":"6","key":"ref7","first-page":"709","article-title":"Screening endoscopy before bariatric surgery: a series of 448 patients","volume":"4","author":"Loewen M","year":"2008","journal-title":"SOARD"},{"key":"ref8","doi-asserted-by":"crossref","first-page":"1367","DOI":"10.1381\/0960892042583806","article-title":"Endoscopy plays an important preoperative role in bariatric surgery","volume":"14","author":"Sharaf RN","year":"2004","journal-title":"Obes Surg"},{"issue":"6","key":"ref9","first-page":"709","article-title":"Screening endoscopy before bariatric surgery: a series of 448 patients","volume":"4","author":"Loewen M","year":"2008","journal-title":"SOARD"},{"issue":"2","key":"ref10","first-page":"144","article-title":"Preoperative upper gastrointestinal endoscopy in obese patients undergoing bariatric surgery: is it necessary?","volume":"4","author":"Almeida AM","year":"2008","journal-title":"SOARD"},{"issue":"8","key":"ref11","doi-asserted-by":"crossref","first-page":"1996","DOI":"10.1007\/s00464-010-0893-5","article-title":"Effort, safety, and findings of routine preoperative endoscopic evaluation of morbidly obese patients undergoing bariatric surgery","volume":"24","author":"K\u00fcper MA","year":"2010","journal-title":"Surg Endosc"},{"issue":"8","key":"ref12","doi-asserted-by":"crossref","first-page":"684","DOI":"10.1177\/000313480407000805","article-title":"Routine preoperative upper endoscopy for laparoscopic gastric bypass: is it necessary?
