Eating avoidance disorder and Wernicke-Korsakoff syndrome following gastric bypass: an under-diagnosed association.

Wernicke-Korsakoff syndrome (WKS) and disordered eating behavior have been reported separately after bariatric surgery. We report a patient who following a bariatric operation developed WKS associated with a disturbed eating behavior without vomiting. This morbidly obese man developed an intense fear of gaining weight in the postoperative period and engaged in an extreme form of "food avoidance behavior". 2 months postoperatively after severe weight loss, he was hospitalized with disorientation and an amnesic syndrome. He was discharged 2 months later with stable weight and regular eating habits. Despite this, at the last follow-up visit 2 years postoperatively, he still had a residual partial amnesic syndrome. The surgical team must be aware of peculiar forms of pathological eating that may appear after bariatric surgery; the emergence of an eating avoidance disorder may be associated with the development of WKS.

Cirurgia bariátrica: aspectos clínico-cirúrgicos e psiquiátricos / Bariatric surgery: clinical, surgical and psychiatric aspects

A obesidade grau III é uma doença crônica, de etiologia multifatorial, que acarreta prejuízos importantes à saúde do indivíduo. Devido a sua gravidade e difícil manejo clínico, novas estratégias de tratamento têm sido propostas, dentre as quais destaca-se a cirurgia bariátrica. O objetivo deste artigo é apresentar uma atualização sobre as técnicas cirúrgicas, assim como aspectos clínicos e psiquiátricos envolvidos com este procedimento. Como pacientes com obesidade grave podem apresentar várias complicações clínicas e um aumento da psicopatologia, é de extrema importância uma avaliação multidisciplinar criteriosa visando a reduzir possíveis complicações pós-operatórias.
