Variation and outcomes of liver-reducing dietary regimens before bariatric surgery: a national retrospective cohort study.

Background: Liver-reducing diets (LRDs) are mandated prior to bariatric surgery, but there are no guidelines on their implementation.

Objective: To establish the variation and effectiveness of LRDs utilized in clinical practice.

Setting: A nationwide, multicenter, retrospective cohort study.

Remission of type 2 diabetes after gastric bypass and banding: mechanisms and 2 year outcomes.

Objective: To investigate the rate of type 2 diabetes remission after gastric bypass and banding and establish the mechanism leading to remission of type 2 diabetes after bariatric surgery.

Summary Background Data: Glycemic control in type 2 diabetic patients is improved after bariatric surgery.

Methods: In study 1, 34 obese type 2 diabetic patients undergoing either gastric bypass or gastric banding were followed up for 36 months.

Ghrelin and metabolic surgery.

Metabolic surgery is the most effective treatment for morbid obesity. Ghrelin has been implicated to play a role in the success of these procedures. Furthermore, these operations have been used to study the gut-brain axis.

Reduced phenytoin levels in an epileptic patient following Roux-En-Y gastric bypass for obesity.

Despite widespread uptake of bariatric procedures for severe obesity, changes in pharmacodynamics after surgery are poorly understood. We report an epileptic patient who had a seizure following gastric bypass, although he had been asymptomatic for 30 years and without any change in his treatment. Phenytoin levels were undetectable despite a high dose.

The gut hormone response following Roux-en-Y gastric bypass: cross-sectional and prospective study.

Background: Bariatric surgery is the most effective treatment option for obesity, and gut hormones are implicated in the reduction of appetite and weight after Roux-en-Y gastric bypass. Although there is increasing interest in the gut hormone changes after gastric bypass, the long-term changes have not been fully elucidated.

Methods: Thirty-four participants were studied cross-sectionally at four different time points, pre-operatively (n = 17) and 12 (n = 6), 18 (n = 5) and 24 months (n = 6) after laparoscopic Roux-en-Y gastric bypass.

Three hundred laparoscopic Roux-en-Y gastric bypasses: managing the learning curve in higher risk patients.

Background: Bariatric surgery is expanding and the increasing workload needs to be undertaken safely in new surgical centres with no previous bariatric experience. The laparoscopic Roux-en-Y gastric bypass (LRYGB) has a steep learning curve with documented high risk. We present the results for the first 300 cases of LRYGB in a new centre.

Obesity, gut hormones, and bariatric surgery.

Obesity is becoming the healthcare epidemic of this century. Bariatric surgery is the only effective treatment for morbid obesity. Gut hormones are key players in the metabolic mechanisms causing obesity.

After bariatric surgery, what vitamins should be measured and what supplements should be given?

Bariatric surgery is the most effective treatment for morbid obesity. Although calorie malabsorption does not occur in most bariatric procedures, micronutrient deficiencies are possible. Multivitamin supplementation is essential following bariatric surgery.
