Anormalidade congênita caracterizada pela formação de bolsa externa ou saco no íleo. É um remanescente do saco vitelino embrionário no qual o ducto vitelino não conseguiu fechar. Durante o início da gestação, o ducto onfalomesentérico ou vitelino conecta o saco vitelino fetal ao intestino primitivo. Por volta de 7 a 8 semanas de gestação, esse ducto normalmente está completamente obliterado. Um divertículo de Meckel ocorre quando essa estrutura não consegue ser reabsorvida completamente. | |||
