RESUMO

INTRODUCTION: laparoscopic Roux-en-Y Gastric Bypass (LRYGB) has been a revolutionary intervention for weight loss with reduction of up to 60-70% of excess body weight. However, these outcomes are not as well validated at the extremes of age, where the safety of the intervention still has some caveats. The aim of this study is to assess the efficacy and safety of primary LRYGB among different age groups. METHODS: the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was queried for patients who underwent primary LRYGB from January 2014 to December 2017 at a single institution. Four groups were created and compared by dividing our sample by age quartiles. The primary outcome was percent excess weight loss (%EWL) at 1 year. Additional operative outcomes and complications were also compared across groups. RESULTS: a total of 1013 patients underwent non-revisional LRYGB during the study period. Mean %EWL at one year was 55%. When compared between quartiles, there was a statistically significant difference in %EWL: 1st 62%, 2nd 57%, 3rd 54% and 4th 47% (p=0.010). The differences in the secondary outcomes between age groups did not demonstrate statistical significance. CONCLUSIONS: though patients in the fourth age quartile (range) did not demonstrate a statistically significant increase in adverse outcomes, they did lose less weight compared to other cohorts. The %EWL at one year after RYGB varied by age in our cohort. Goals after bariatric surgery should be individualized as weight loss is less robust with aging.

RESUMO Introdução: o Bypass Gástrico Laparoscópico em Y de Roux (LRYGB) tem sido uma intervenção revolucionária para perda de peso com redução de até 60-70% do excesso de peso corporal. No entanto, esses resultados não são tão bem validados nos extremos de idade, onde a segurança da intervenção ainda possui algumas ressalvas. O objetivo deste estudo é avaliar a eficácia e segurança do LRYGB entre diferentes faixas etárias. Métodos: O banco de dados do Programa de Acreditação e Melhoria da Qualidade da Cirurgia Metabólica e Bariátrica (MBSAQIP) foi consultado para pacientes submetidos a LRYGB de janeiro de 2014 a dezembro de 2017 em uma única instituição. Quatro grupos foram criados e comparados dividindo a amostra por quartis de idade. O desfecho primário foi perda percentual de excesso de peso (%EWL) em 1 ano. Resultados: 1013 pacientes foram submetidos a LRYGB durante o período do estudo. A média de %EWL em um ano foi de 55%. Quando comparados entre os quartis, houve diferença significante no %EWL: 1º 62%, 2º 57%, 3º 54%, e 4º 47% (p=0,010). As diferenças nos desfechos secundários entre as faixas etárias não demonstraram significância estatística. Conclusões: embora os pacientes no quarto quartil de idade não tenham demonstrado um aumento estatisticamente significativo nos resultados adversos, eles perderam menos peso em comparação com outras coortes. O %EWL um ano após RYGB variou de acordo com a idade em nossa coorte. Os objetivos após a cirurgia bariátrica devem ser individualizados, pois a perda de peso é menos robusta com o envelhecimento.
