Gastric bypass surgery in the United States, 1998-2002.
ABSTRACT We assessed the prevalence of gastric bypass surgeries in the United States on the basis of data from the 1998 to 2002 National Hospital Discharge Survey. Between 1998 and 2002, rates (per 100,000 adults) increased significantly (P<.001): from 7.0 to 38.6. This observed increase in the rate of gastric bypass surgery for the treatment of obesity may be attributed in part to improvements in surgical technique, improved patient outcomes, and increased popularity of this procedure.

ABSTRACT: The use of bariatric surgery for the treatment of morbid obesity has increased annually for the last decade. Although many studies have demonstrated the efficacy and durability of bariatric surgery for weight loss, there are limited data regarding long-term side effects of these procedures. Recently, there has been an increased focus on the impact of bariatric surgery on bone metabolism. Bariatric surgery utilizes one or more of three mechanisms of action resulting in sustained weight loss. These include restriction (gastric banding, vertical banded gastroplasty and sleeve gastrectomy), malabsorption surgery with or without associated restriction (Roux en Y gastric bypass, duodenal switch, biliopancreatic diversion and jejunoileal bypass) and changes in gut-derived hormones that control energy metabolism also referred to as neuro-hormonal control of energy metabolism (Roux en Y gastric bypass, duodenal switch, biliopancreatic diversion, jejunoileal bypass, surgical procedures as above and gastric sleeve). Weight reduction has been associated with increased bone resorption but the mechanisms behind this have not yet been fully elucidated. Each of the mechanisms of action of bariatric surgery (restriction, malabsorption, neuro-hormonal control of energy metabolism) may uniquely affect bone resorption. In this paper we will review the current state of knowledge regarding the relationship between bariatric surgery and bone metabolism with emphasis on possible mechanisms of action such as malnutrition, hormonal interactions and mechanical unloading of the skeleton. Further, we suggest a future research agenda.International Journal of Obesity advance online publication, 17 July 2012; doi:10.1038/ijo.2012.115.International journal of obesity (2005) 07/2012; 36(11).

ABSTRACT: Obesity has profound negative consequences on female reproduction as well as on the metabolic health of offspring. Bariatric surgery is the most effective method for sustained weight loss. A critical question is whether bariatric surgery can reverse the deleterious effects of obesity on both female reproduction and subsequent offspring. Vertical sleeve gastrectomy (VSG) is a bariatric procedure rapidly growing in popularity because it provides weight loss and other metabolic benefits that are comparable to those offered by the more complicated Roux-en-Y gastric bypass (RYGB). Female rats rendered obese on a high-fat diet (HFD) underwent either VSG or sham surgery. Like their male counterparts, females had significant metabolic improvements including reduced adiposity and improved glucose tolerance. After VSG, female rats showed a more normal reproductive cycle. Despite these maternal benefits, the offspring of dams receiving VSG were born smaller and lighter than offspring of control dams that underwent sham surgery. When maintained on an HFD after puberty, these adult offspring had a greater propensity to develop glucose intolerance and increased adiposity than the offspring of lean mothers or obese mothers who underwent sham surgery. These data suggest that weight loss alone by obese mothers is not sufficient to reverse the deleterious effects of an HFD and obesity on their offspring.Science translational medicine 08/2013; 5(199):199ra112.

ABSTRACT: The number of people who are obese or morbidly obese is increasing in the United States. Currently, the most effective means of losing a substantial amount of weight and maintaining the weight loss is bariatric surgery, and health care providers, especially those in surgical services, must be able to safely care for patients undergoing these surgeries. Financial implications of starting a bariatric surgery program and the ongoing costs must be fully understood and supported by both administrators and employees. Special equipment and supplies are needed to handle the higher weight of bariatric patients, and careful planning is required for adequate medical and nursing expertise, staffing, equipment, supplies, facility resources, and patient support services.AORN journal 02/2013; 97(2):195-209.
