INTRODUCTION: In addition to being associated with worsening of diseases related to metabolic syndrome and musculoskeletal disorders, obesity in older adults increases the risk of falls, frailty syndrome, depression, and dementia, with consequent functional loss. Among all treatments available, bariatric surgery is an option for eligible patients. OBJECTIVES: To discuss aspects related to the safety and benefits of bariatric surgery for the control or remission of comorbidities in older adults. METHODS: This literature review was carried out in databases, using the following keywords: bariatric surgery and elderly or aged or older adult and comorbidities or safety. We included clinical trials, observational studies, comparative studies, and reviews that evaluated the effect of bariatric surgery on the control or remission of comorbidities in older adults. RESULTS: In recent years, several studies have evidenced not only control or remission of comorbidities, such as diabetes, hypertension, and sleep apnea syndrome, but also a low rate of complications, similar to those observed in young people. CONCLUSIONS: Based on the results of these studies, bariatric surgical procedures can be indicated for eligible older adults, without age restriction, taking into account functional and life expectancy aspects.

O qUE pOdE SER fEitO paRa REdUziR a incidência dE héRnia inciSiOnal póS-bypaSS gáStRicO EM y dE ROUx? Objetivo. Determinar se as diferentes técnicas de fechamento da parede abdominal podem reduzir a incidência de hérnia incisional em pacientes submetidos à cirurgia bariátrica. Método. Foram analisados dados de 150 pacientes, divididos em três grupos: no grupo PDS, apenas o fio cirúrgico polidioxanone (PDS) foi utilizado no fechamento da parede abdominal, no grupo PRO-0, além de PDS, utilizou-se prolene-0 como reforço, e no grupo PRO-2, além de PDS, utilizou-se prolene-2 como reforço. A incidência de hérnia incisional foi observada por 22 meses, analisando-se a idade, sexo, índice de massa corporal (IMC), co-morbidades, tempo de aparecimento da hérnia no pós-operatório e as complicações pós-cirúrgicas. Resultados. Ocorreram sete hérnias incisionais no grupo PDS (14%), três no PRO-0 (6%) e uma no PRO-2 (2%).
