ABSTRACT
ABSTRACT

Introduction:

Glucagon-like peptide-2 (GLP-2) is a gastrointestinal hormone whose effects are predominantly trophic on the intestinal mucosa.

Aim:

Critically evaluate the current literature on the influence of bariatric/metabolic surgery on the levels of GLP-2 and its potential clinical implications. Method s Narrative review through online research on the databases Medline and Lilacs. There were six prospective human studies, two cross-sectional human studies, and three experimental animal studies selected.

Results:

There is evidence demonstrating significant increase in the levels of GLP-2 following gastric bypass, Scopinaro operation, and sleeve gastrectomy. There are no differences between gastric bypass and sleeve gastrectomy in regards to the increase in the GLP-2 levels. There is no correlation between the postoperative levels of GLP-2 and the occurrence of adequate or insufficient postoperative weight loss.

Conclusion:

GLP-2 plays significant roles on the regulation of nutrient absorption, permeability of gut mucosa, control of bone resorption, and regulation of satiety. The overall impact of these effects potentially exerts a significant adaptive or compensatory effect within the context of varied bariatric surgical techniques.
RESUMO
RESUMO

Introdução:

O peptídeo semelhante ao glucagon-2 (GLP-2) é hormônio gastrointestinal com efeitos predominantemente tróficos sobre a mucosa intestinal.

Objetivo:

Avaliar criticamente a literatura atual a respeito da cirurgia bariátrica/metabólica sobre os níveis de GLP-2 e suas potenciais implicações clínicas.

Métodos:

Revisão narrativa realizada através de pesquisa on-line nas bases de dados Medline e LILACS. Foram selecionados seis estudos prospectivos em humanos, dois transversais em humanos e três experimentais em animais.

Resultados:

Existem evidências demonstrando aumento significativo nos níveis de GLP-2 após o bypass gástrico, a operação de Scopinaro e a gastrectomia vertical. Não foram observadas diferenças entre o bypass gástrico e a gastrectomia vertical em relação ao aumento do GLP-2. Não há correlação entre os níveis de GLP-2 e a ocorrência de perda de peso pós-operatória adequada ou insuficiente.

Conclusão:

O GLP-2 desempenha importantes papel sobre a regulação da absorção de nutrientes, permeabilidade da mucosa intestinal, controle da reabsorção óssea e regulação da saciedade. O impacto combinado destes efeitos potencialmente exerce efeito adaptativo ou compensatório importante no contexto das diferentes técnicas bariátricas.
