BACKGROUND: Although bariatric surgery is today’s gold standard treatment for obesity, weight regain affects the success rate of the procedure. Recent studies have identified psychiatric and neurological factors as possible causes. AIMS: The aim of this study was to evaluate the influence of psychiatric diseases on the outcome and long-term success of bariatric surgeries and find a weight regain threshold that has an acceptable sensibility to mental health-related issues to be used in research and clinical studies. METHODS: This is a observational study of bariatric patients submitted to Roux-en-Y bypass or sleeve gastrectomy, with a postoperative time of 2–10 years to access weight regain, depression, and binge-eating disorder. RESULTS: Of 217 patients studied, 163 were women and 54 were men, with an average postoperative time of 5.2±2.6 years. Weight regain was experienced in 35% of the patients, binge-eating disorder in 24.9%, and depression in 24%. The greater weight before surgery, body mass index (BMI), percentage increase to maximum weight loss, and time postoperatively all have a significant positive correlation with weight regain (p=0.045, p=0.026, p<0.001, and p<0.001, respectively). A significant association between binge-eating disorder, depression, and anxiety with weight regain (p=0.004, p=0.008, and p=0.001, respectively) was found. CONCLUSIONS: The significant weight regain rates with significant impact on psychiatric disorders highlight the need for continuous postoperative monitoring focused on the psychiatric aspects of obesity to aid surgeries’ long-term success.
O diagnóstico de apendicite aguda na mulher em idade fértil é um desafio para o cirurgião devido ao alto índice de explorações cirúrgicas negativas. O objetivo deste trabalho foi estabelecer um índice de probabilidade diagnóstica e o valor da videolaparoscopia nestes casos. Foram analisadas, prospectivamente, 34 mulheres em idade fértil referendadas para o serviço com diagnóstico de apendicite aguda. As pacientes foram submetidas à videolaparoscopia de urgência, e o tratamento cirúrgico, quando indicado, foi realizado por videolaparoscopia sempre que possível. Entre as 34 pacientes, 17 apresentaram apendicite aguda à videolaparoscopia, sendo que 15 delas foram operadas por esta via. As 17 pacientes que apresentaram outro diagnóstico à videolaparoscopia não necessitaram de qualquer tratamento cirúrgico em 13 casos, sendo que quatro pacientes foram submetidas a operação por via aberta. O quadro clínico foi medido por um índice de probabilidade para apendicite aguda, e os resultados videolaparoscópicos foram relacionados a este índice. A conclusão é que a videolaparoscopia é um instrumento importante na abordagem propedêutica e terapêutica do abdome agudo da mulher em idade fértil, possibilitando uma maior precisão diagnóstica nestes casos e evitando laparotomias não terapêuticas.
