Failure of Pre-Operative Resting Energy Expenditure in Predicting Weight Loss After GastroplastyTo evaluate the predictive efficacy of preoperative resting energy expenditure (REE) on weight loss after vertical banded gastroplasty (VBG). When subjected to a gastric restriction procedure of similar extent, the patients with higher energy expenditure should experience a greater negative energy balance than those with lower-energy expenditure, and thus, lose more weight, thereby making REE a reliable predictor of weight loss after VBG. Method This was a prospective investigation after VBG, taking into account the relationship between preoperative REE values and the results at 1-year follow-up in terms of weight loss and success of the procedure. The correlations were evaluated by multiple and logistic regression analysis. Results The weight loss and the outcome at 1 year after vertical banded gastroplasty seemed to be completely independent of preoperative energy expenditure. Discussion These findings suggest that, despite gastric restriction, patients may voluntarily adjust their energy intake, and that the weight outcome after vertical banded gastroplasty is influenced more by behavioral and cognitive variables than by biological or surgical factors.
