title: Preoperative Medical Weight Management in Bariatric Surgery: a Review and Reconsideration.
abstract: Bariatric surgery is the most robust treatment for extreme obesity. The impact of preoperative medical weight management sessions designed, in theory, with the primary goal of promoting preoperative weight loss, is unclear. This paper reviews studies that have investigated the relationship between preoperative weight loss and bariatric surgical outcomes, both with respect to postoperative weight loss and complications. We conclude that the most robust of preoperative interventions has not been implemented or evaluated in a manner which would conclusively assess the value of this element of care. We offer a reconsideration of the role of preoperative medical weight management and provide recommendations for future research in this area.
