Aim
The continual advances in our knowledge of the pathogenesis and hormonal disorders of morbid obesity lead to new studies in experimental animals and the development of new technical options. The aim is to asses whether ileal transposition can be a good treatment of morbid obesity associated with diabetes mellitus due to the action of intestinal peptide Glp-1 (enteroglucagon) compared to gastric bypass and vertical gastroplasty (VGB).
Material and methods
Trial enviroment: experimental animals ZDF rats (Zucker Diabetic Fatty rats). Subjects of the study: three groups of 10 animals each one divided as: a) ileal tranposition; b) gastro-jejunal bypass; c) vertical gastroplasty. Parameters to determine: weight loss, levels of glycaemia, enteroglucagon, insulin and ghrelin in blood, one week before the operation as a baseline control, and 15 days after the surgical procedure.
Results
Gastrojejunal bypass produces the most significant weight loss. There is a significant decrease in intake in all groups. Hyperinsulinaemia and hyperglycaemia tend to decrease after surgery in all groups, but in ileal transposition there is better control of ketosis. After gastrojejunal bypass and ileal transposition, we observed an increase in GLP-1 levels but were only significant in ileal transposition.
Conclusions
Ileal transposition produces a decrease in plasma glucose and better control of diabetes mellitus, which could benefit patients affected by morbid obesity and poor metabolic control. More studies are needed on other models of obesity. A model of exogenous and reversible obesity could be a good option to study the real benefits of the interventions.
