Introduction : Obesity is related with higher incidence of gastroesophageal reflux disease. Antireflux surgery has inadequate results when associated with obesity, due to migration and/or subsequent disruption of antireflux wrap. Gastric bypass, meanwhile, provides good control of gastroesophageal reflux. Objective: To evaluate the technical difficulty in performing gastric bypass in patients previously submitted to antireflux surgery, and its effectiveness in controlling gastroesophageal reflux. Methods: Literature review was conducted between July to October 2016 in Medline database, using the following search strategy: (“Gastric bypass” OR “Roux-en-Y”) AND (“Fundoplication” OR “Nissen ‘) AND (“Reoperation” OR “Reoperative” OR “Revisional” OR “Revision” OR “Complications”). Results: Were initially classified 102 articles; from them at the end only six were selected by exclusion criteria. A total of 121 patients were included, 68 women. The mean preoperative body mass index was 37.17 kg/m² and age of 52.60 years. Laparoscopic Nissen fundoplication was the main prior antireflux surgery (70.58%). The most common findings on esophagogastroduodenoscopy were esophagitis (n=7) and Barrett’s esophagus (n=6); the most common early complication was gastric perforation (n=7), and most common late complication was stricture of gastrojejunostomy (n=9). Laparoscopic gastric bypass was performed in 99 patients, with an average time of 331 min. Most patients had complete remission of symptoms and efficient excess weight loss. Conclusion: Although technically more difficult, with higher incidence of complications, gastric bypass is a safe and effective option for controlling gastroesophageal reflux in obese patients previously submitted to antireflux surgery, with the added benefit of excess weight loss.

BackgroundGastroesophageal reflux disease is a worldwide prevalent condition that exhibits a large variety of signs and symptoms of esophageal or extra-esophageal nature and can be related to the esophagic adenocarcinoma. In the last few years, greater importance has been given to the influence of physical exercises on it. Some recent investigations, though showing conflicting results, point to an exacerbation of gastroesophageal reflux during physical exercises.AimTo evaluate the influence of physical activities in patients presenting with erosive and non erosive disease by ergometric stress testing and influence of the lower esophageal sphincter tonus and body mass index during this situation.MethodsTwenty-nine patients with erosive disease (group I) and 10 patients with non-erosive disease (group II) were prospectively evaluated. All the patients were submitted to clinical evaluation, followed by upper digestive endoscopy, manometry and 24 h esophageal pH monitoring. An ergometric testing was performed 1 h before removing the esophageal pH probe. During the ergometric stress testing, the following variables were analyzed: test efficacy, maximum oxygen uptake, acid reflux duration, gastroesophageal reflux symptoms, influence of the lower esophageal sphincter tonus and influence of body mass index in the occurrence of gastroesophageal reflux during these physical stress.ResultsMaximum oxigen consumption or VO 2 max, showed significant correlation when it was 70% or higher only in the erosive disease group, evaluating the patients with or without acid reflux during the ergometric testing (p=0,032). The other considered variables didn't show significant correlations between gastroesophageal reflux and physical activity (p>0,05).Conclusions1) Highly intensive physical activity can predispose the occurrence of gastroesophageal reflux episodes in gastroesophageal reflux disease patients with erosive disease; 2) light or short sessions of physical activity have no influence on reflux, regardless of body mass index; 3) the lower esophageal sphincter tonus does not influence the occurrence of reflux disease episodes during exercise testing.

DESCRITORES -Acalásia esofágica. Refluxo gastroesofágico. Espasmo esofagiano difuso.RESUMO -Introdução -Demonstra-se que os distúrbios motores esofágicos como o espasmo esofageano difuso podem progredir para acalásia. Também é conhecida a associação entre a doença do refluxo gastroesofágico e alguns destes distúrbios.Relato do caso -Paciente com queixa de dor torácica, disfagia e perda de peso há dois meses. A primeira endoscopia digestiva alta sugeriu apenas dismotilidade esofágica. Posteriormente, realizou manometria esofágica que evidenciou alterações em corpo compatíveis com espasmo esofageano difuso, sem alterações no esfíncter esofageano inferior. Na oportunidade iniciou o tratamento com pantoprazol e nifedipina que se estendeu por oito meses; no entanto manteve-se sintomática. Após suspender medicação por 10 dias, realizou pH-metria esofageana prolongada constatando-se refluxo gastroesofágico patológico combinado e refluxo proximal, sendo submetida ao tratamento com esomeprazol e mantida a nifedipina. Após dois meses, com a persistência dos sintomas, realizou-se nova endoscopia que evidenciou estase alimentar e manometria esofágica com aperistalse completa de corpo. Neste momento, optou-se por cardiomiotomia a Heller com fundoplicatura laparoscópica. A endoscopia do terceiro mês do pós-operatório evidenciou fundoplicatura bem ajustada ao aparelho. No seguimento a médio prazo ela permanece assintomática. Conclusão -Existe correlação entre os distúrbios motores esofágicos e a doença do refluxo gastroesofágico, e o tratamento cirúrgico para corrigir a acalásia e o refluxo gastroesofágico ao mesmo tempo, pode ser indicado em casos selecionados.ABSTRACT -Background -It is shown that esophageal motor disorders, such as diffuse esophageal spasm, may progress to achalasia. It is also known a link between gastroesophageal reflux disease and some of these motor disorders. Case report -Patient complaining of chest pain, dysphagia and weight loss for two months. The first endoscopy suggested only motility disorders. Esophageal manometry was done and showed changes in body compatible with diffuse esophageal spasm, without changes in lower esophageal sphincter. Treatment with pantoprazole and nifedipine for eight months was done, but the patient remained symptomatic. After stopping medication for 10 days, an esophageal pH-metry was realized and showed gastro-esophageal reflux. She was submitted to treatment with esomeprazole and nifedipine. After two months, with persistence of the symptoms, a new endoscopy showed food stasis, and esophageal manometry body esophageal aperistalsis. At this point, surgical treatment (Heller cardiomyotomy with fundoplication) was done. Endoscopy of the third postoperative month showed fundoplication well adjusted to the endoscope. In follow-up, patient remained asymptomatic. ConclusionThere is a correlation between esophageal motor disorders and gastroesophageal reflux disease, and surgical treatment to correct achalasia and gastroesophageal reflux at the same time, may be indicated in se...
