Thus, these studies confirm that the vertical gastrectomy is not purely restrictive but also directly produces hormonal changes. These hormonal changes are also seen in increased GLP-1 and PYY, similar to changes seen in the Roux-en-Y gastric bypass.
Por lo tanto, confirman estos estudios que la gastrectomía vertical no es una cirugía puramente restrictiva sino que también produce cambios directamente hormonales.
