Weight Loss Analysis According to Different Formulas after Sleeve Gastrectomy With or Without Antral Preservation: a Randomised Study.

Background: The measurement of weight loss after bariatric surgery is under constant review in order to obtain the ideal standard for reporting weight loss. Several formulas have been proposed for this purpose. Our goal is to analyse weight loss after sleeve gastrectomy, with or without antrum preservation through different measurement formulas.
