Enterohormonal changes after digestive adaptation: five-year results of a surgical proposal to treat obesity and associated diseases.

Background: Recent physiological knowledge allows the design of bariatric procedures that aim at neuroendocrine changes instead of at restriction and malabsorption. Digestive adaptation is a surgical technique for obesity based in this rationale.

Methods: The technique includes a sleeve gastrectomy, an omentectomy and a jejunectomy that leaves initial jejunum and small bowel totaling at least 3 m (still within normal variation of adult human bowel length).
