RESUMO
OBJECTIVE: It was to report on Brazilian cases of neurological complications from bariatric surgery. The literature on the subject is scarce. METHOD: Cases attended by neurologists in eight different Brazilian cities were collected and described in the present study. RESULTS: Twenty-six cases were collected in this study. Axonal polyneuropathy was the most frequent neurological complication, but cases of central demyelination, Wernicke syndrome, optical neuritis, radiculits, meralgia paresthetica and compressive neuropathies were also identified. Twenty-one patients (80%) had partial or no recovery from the neurological signs and symptoms. CONCLUSION: Bariatric surgery, a procedure that is continuously increasing in popularity, is not free of potential neurological complications that should be clearly presented to the individual undergoing this type of surgery. Although a clear cause-effect relation cannot be established for the present cases, the cumulative literature on the subject makes it important to warn the patient of the potential risks of this procedure.

OBJETIVO: Foi relatar casos de pacientes brasileiros com complicações neurológicas da cirurgia bariátrica. A literatura no assunto é escassa. MÉTODO: Foram reunidos e descritos casos atendidos por neurologistas em oito cidades brasileiras diferentes. RESULTADOS: Vinte e seis casos foram coletados neste estudo. A complicação neurológica mais frequente foi a polineuropatia axonal, mas também foram identificados casos de desmielinização central, síndrome de Wernicke, neurite óptica, radiculites, meralgia parestésica e neuropatias compressivas. Vinte e um pacientes (80%) não tiveram recuperação ou tiveram apenas recuperação parcial dos sinais e sintomas neurológicos. CONCLUSÃO: A cirurgia bariátrica, procedimento cada vez mais popularizado, não está livre de potenciais complicações neurológicas as quais deveriam ser claramente expostas aos indivíduos que a ela se submetem. Embora não possa ser estabelecida uma clara relação causa-efeito entre essa cirurgia e os sinais e sintomas referidos nos casos aqui apresentados, a literatura consultada mostrou ser importante alertar o indivíduo acerca dos riscos potenciais envolvidos nesse procedimento.
