ABSTRACT

This Brazilian multi-society position statement on emerging bariatric and metabolic surgical procedures was issued by the Brazilian Society of Bariatric and Metabolic Surgery (SBCBM), the Brazilian College of Digestive Surgery (CBCD), and the Brazilian College of Surgeons (CBC). This document is the result of a Brazilian Emerging Surgeries Forum aimed at evaluating the results of surgeries that are not yet listed in the Federal Council of Medicine (CFM), the regulatory agency that oversees and regulates medical practice in Brazil. The Forum integrated more than 400 specialists and academics with extensive knowledge about bariatric and metabolic surgery, representing the three surgical societies: SBCBM, CBC, and CBCD. International speakers participated online and presented their experiences with the techniques under discussion, emphasizing the regulatory policies in their countries. The indications for surgery and the subsequent procedures were carefully reviewed, including one anastomosis gastric bypass (OAGB), single anastomosis duodeno-ileal with sleeve gastrectomy (SADI-S or OADS), sleeve gastrectomy with transit bipartition (SGTB), and sleeve gastrectomy with ileal interposition (SGII). The recommendations of this document are based on an extensive literature review and discussions among bariatric surgery specialists from the three surgical societies. We concluded that patients with a body mass index over 30 kg/m ² may be candidates for metabolic surgery in the presence of comorbidities (arterial hypertension and type 2 diabetes) with no response to clinical treatment of obesity or in the control of other associated diseases. Regarding the surgical procedures, we concluded that OAGB, OADS, and SGTB are associated with low morbidity rates, satisfactory weight loss, and resolution of obesity-related comorbidities such as diabetes and arterial hypertension. SGII was considered a good and viable promising surgical alternative technique. The recommendations of this statement aim to synchronize our societies with the sentiments and understandings of most of our members and also serve as a guide for future decisions regarding bariatric surgical procedures in our country and worldwide.

RESUMO

Esta declaração multissocietária de posicionamento sobre novos procedimentos cirúrgicos bariátricos e metabólicos emergentes foi emitida pela Sociedade Brasileira de Cirurgia Bariátrica e Metabólica (SBCBM), pelo Colégio Brasileiro de Cirurgia Digestiva (CBCD) e pelo Colégio Brasileiro de Cirurgiões (CBC). Este documento é resultado do Fórum Brasileiro de Cirurgias Emergentes, realizado com o objetivo de avaliar os resultados de cirurgias ainda não listadas no Conselho Federal de Medicina (CFM), órgão regulador que fiscaliza e regulamenta a prática médica no Brasil. O Fórum integrou mais de 400 especialistas e acadêmicos com amplo conhecimento sobre cirurgia bariátrica e metabólica, representando as três sociedades cirúrgicas: SBCBM, CBC e CBCD. Palestrantes internacionais participaram online e apresentaram suas experiências com as técnicas em discussão, enfatizando as políticas regulatórias de seus países. As indicações para cirurgia e os procedimentos subsequentes foram cuidadosamente revisados, incluindo bypass gástrico de uma anastomose (OAGB), anastomose duodeno-Ileal única com gastrectomia vertical (OADS ou SADI-S), gastrectomia vertical com bipartição de trânsito (SGTB) e gastrectomia vertical com interposição ileal (SGII). As recomendações deste documento são baseadas em extensa revisão da literatura e discussões entre especialistas em cirurgia bariátrica das três sociedades cirúrgicas. Concluímos que pacientes com índice de massa corpórea (IMC) acima de 30 kg/m2 podem ser candidatos à cirurgia metabólica na presença de comorbidades (hipertensão arterial e diabetes tipo 2), sem resposta ao tratamento clínico da obesidade ou no controle de outras doenças associadas. Em relação aos procedimentos cirúrgicos, concluímos que OAGB, OADS e SGTB estão associados a baixas taxas de morbidade e com perda de peso satisfatória e resolução de comorbidades relacionadas à obesidade, como diabetes e hipertensão arterial. A SGII foi considerada uma boa e viável técnica cirúrgica, sendo considerada uma alternativa promissora. As recomendações desta declaração visam sincronizar nossas sociedades com os sentimentos e entendimentos da maioria de nossos membros e também servir como um guia para futuras decisões sobre procedimentos cirúrgicos bariátricos em nosso país e no mundo.

Humans against Obesity: Who Will Win?

Benjamin Caballero (2019)

The global obesity epidemic continues its relentless advance, currently affecting >2 billion people. This paper explores alternative ways to assess the potential disease impact of the epidemic, which is currently based almost exclusively on body mass index (BMI) data. It also argues in favor of concerted efforts to modify the built ecosystem that is driving the obesity epidemic. Most of the epidemiologic data on obesity are based on BMI (in kg/m 2 ) and use the ranges of 18.5–24.9 for normality, 25–29.9 for overweight, and ≥30 for obesity. But the gap between the median of the “normal” BMI distribution (∼22) and the current population BMI of, for example, the United States (27.7) has become so wide that it is unlikely that we will be able to close that gap in the near future. Furthermore, the correlation between BMI and disease risk is not linear. Over 60% of the global disease burden of obesity affects individuals with a BMI ≥30, who comprise only ∼10% of the global population of overweight/obese persons. Furthermore, BMI accounts for only ∼17% of the risk of insulin resistance and subsequent type 2 diabetes in the BMI ≥25 population. Epigenetics, specifically DNA methylation, appears to play a far more important role than BMI in determining the risk of obesity's comorbidities, such as diabetes. Similarly, socioeconomic status carries a higher risk than BMI level for the development of obesity-related noncommunicable diseases. Finally, the built environment that sustains our species’ lifestyle is a major driver of the obesity epidemic. Modifying that ecosystem will require no less than a social movement, one able to promote and sustain the necessary coordinated action of virtually all sectors of society.
