چکیده
Background The gastric bypass has nutritional and electrolyte disturbances rate of approximately 17%. The most common deficits are protein malnutrition, ferric and zinc, in addition to the vitamin. Although rare, some malnutrition stages reach such severity that ends up being necessary hospitalization and sometimes revisional or reversal surgical procedures. Aim: To present a proposal of surgical revision for treatment of severe malnutrition after bariatric surgery. Methods: The procedure is to reconstitute the food transit through the duodenum and proximal jejunum, keeping the gastric bypass restrictive component. As an additional strategy, the gastric fundus resection is performed, aiming to intensify the suppression of the greline and avoiding excessive weight regain. Results: After initial stabilization, nutritional and electrolytic support, the procedure was performed in two patients as definitive treatment of malnutrition status. Good results were observed at one year follow up. Conclusion: As improvement option and/or resolution of the nutritional alterations, surgical therapy is one of the alternatives. There is still no consensus on the surgical technique to be performed. This procedure is based on pathophysiological factors for the treatment of this condition, with good initial results, without significant clinical alterations. Longer follow-up will determine its effectiveness. Racional: O bypass gástrico consta com taxa de distúrbios nutricionais e eletrolíticos de aproximadamente 17%. Os déficits mais frequentes são a desnutrição proteica, férrica e de zinco, além das vitamínicas. Apesar de raros, alguns quadros de desnutrição atingem tal gravidade que acaba sendo indicada internação e, por vezes, procedimentos cirúrgicos revisionais ou de reversão. Objetivo: Apresentar proposta de cirurgia revisional para tratamento de desnutrição severa após bypass gástrico. Métodos: O procedimento consiste em reconstituir o trânsito alimentar pelo duodeno e jejuno proximal, mantendo o componente restritivo do bypass gástrico. Como estratégia adicional, é realizada ressecção do fundo gástrico, visando intensificar a supressão da grelina e evitando reganho excessivo de peso. Resultado: Após estabilização inicial com suporte hidroeletrlítico e nutricional, o procedimento foi realizado em dois pacientes como tratamento definitivo do quadro de desnutrição. Bons resultados foram observados em seguimento de um ano. Conclusão: Como opção de melhora e/ou resolução da defasagem nutricional, a terapia cirúrgica é uma das alternativas. Ainda não há consenso quanto à técnica a ser utilizada. O procedimento aqui apresentado é baseado em fatores fisiopatológicos para o tratamento desta condição, com bons resultados iniciais, sem efeitos colaterais significativos. Seguimento de mais longo prazo é necessário para determinação de sua eficácia.
