BACKGROUND: Metabolic surgery for obese patients with type 2 diabetes (T2D) yields short- and long-term remission rates of 60-90%. Its effects on diabetesassociated complications such as neuropathy and nephropathy have not been well studied to date. Hardly any data are available on this subject with respect to moderately obese patients (body mass index [BMI] 25-35 kg/m2) with insulin-dependent T2D. Our previous studies suggest that, in such patients, treatment with a Roux-en-Y gastric bypass (RYGB) improves diabetic neuropathy...

Roux-en-Y gastric bypass (RYGB) surgery is widely used in the management of morbid obesity. RYGB improves metabolism independently of weight loss by still unknown mechanisms. Bile acids (BAs) are good candidates to explain this benefit, since they regulate metabolic homeostasis and their systemic concentrations increase upon RYGB. Here we analyzed the mechanisms underlying the increase in systemic BA concentrations after RYGB and the role of the liver therein. To this aim, we used the Göttingen-like minipig, a human-size mammalian model, which allows continuous sampling and simultaneous analysis of pre-hepatic portal and systemic venous blood...

Surgical interventions for weight-related diseases (SWRD) may have substantial and sustainable effect on weight reduction, also leading to a higher remission rate of type 2 diabetes (T2D) mellitus than any other medical treatment or lifestyle intervention. The resolution of T2D after Roux-en-Y gastric bypass (RYGB) typically occurs too quickly to be accounted for by weight loss alone, suggesting that these operations have a direct impact on glucose homeostasis. The mechanisms underlying these beneficial effects however remain unclear...

PURPOSE: Bariatric surgery has been associated with bone remodeling changes. The action of adipokines on the expression of receptor activator of nuclear factor kappa β ligand (RANKL) and osteoprotegerin (OPG) and on an increase in sclerostin could be related to these changes. MATERIALS AND METHODS: This study aimed to assess the repercussions of weight loss, fat mass (FM), and fat-free mass (FFM) loss and biochemical and hormonal changes on bone remodeling markers after Roux-en-Y gastric bypass (RYGB)...

Gastroesophageal reflux disease (GERD) is a common disorder that has a well-established connection with obesity. To ameliorate the morbidity associated with obesity, bariatric procedures have become an established pathway to accomplish sustained weight loss. In some procedures, such as with the Roux-en-Y gastric bypass surgery, weight loss is also accompanied by the resolution of GERD symptoms. However, other popular bariatric surgeries, such as the sleeve gastrectomy, have a controversial impact on their effect on reflux...

BACKGROUND: Hyperoxaluria after Roux-en-Y gastric bypass (RYGB) is generally attributed to fat malabsorption. If hyperoxaluria is indeed caused by fat malabsorption, magnitudes of hyperoxaluria and steatorrhea should correlate. Severely obese patients, prior to bypass, ingest excess dietary fat, which can produce hyperphagic steatorrhea. The primary objective of the study was to determine whether urine oxalate excretion correlates with elements of fat balance in severely obese patients before and after RYGB...

BACKGROUND: Intestinal gluconeogenesis (GNG) may play an important role in glucose homeostasis, but there is little information about the condition in humans. OBJECTIVES: To study the relationship between intestinal GNG and insulin resistance, its association with the evolution of morbidly obese patients after bariatric surgery, and the effect of insulin and or leptin. SETTING: Regional university hospital, Malaga (Spain). METHODS: Jejunal mRNA expression of genes involved in GNG was analyzed in 3 groups of morbidly obese patients who underwent Roux-en-Y gastric bypass: with low insulin resistance (MO-low-IR), with high insulin resistance (MO-high-IR), and with type 2 diabetes treated with metformin (MO-metf-T2D)...

BACKGROUND: Obesity and its consequences have now reached worldwide pandemic proportions. Among treatments, bariatric interventions are the most effective for weight reduction. Here, we describe the change in anthropometric measurements (AMs) of 615 adult bariatric procedure patients seen in the private practice of a registered dietitian (RD) in Bogotá, Colombia. METHODS: Observational retrospective study of AMs recorded between 1996 and 2013 for patients who had laparoscopic sleeve gastrectomy (LSG, n = 290), laparoscopic adjustable gastric banding (LAGB, n = 207), and laparoscopic Roux-EN-Y gastric bypass (LRYGB, n = 36) or the non-surgical gastric balloon (GB, n = 82) procedure...

INTRODUCTION: There are several randomised controlled trials (RCTs) that have already shown that metabolic/bariatric surgery achieves short-term and long-term glycaemic control while there are no level 1A of evidence data regarding the effects of surgery on the microvascular complications of type 2 diabetes mellitus (T2DM). PURPOSE: The aim of this trial is to investigate the long-term efficacy and safety of the Roux-en-Y gastric bypass (RYGB) plus the best medical treatment (BMT) versus the BMT alone to improve microvascular outcomes in patients with T2DM with a body mass index (BMI) of 30-34...

Background: The role of gut hormones in glucose homeostasis and weight loss achievement and maintenance after bariatric surgery appears to be a key point in the understanding of the beneficial effects observed following these procedures. Aim: To determine whether there is a correlation between the pre and postoperative levels of both GLP-1 and GLP-2 and the excess weight loss after Roux-en-Y gastric bypass (RYGB). Methods: An exploratory prospective study which enrolled 11 individuals who underwent RYGB and were followed-up for 12 months...

Middle-aged women are at a higher risk of being obese. We examined the trajectory of post-surgical % total weight loss (%TWL) among middle-aged female bariatric patients. We fitted sequential generalized estimating equations models to analyze a sample of women who received bariatric surgery in 1995-2012, aged 40-65 years at the time of surgery (N = 158,292) whose pre-operative body mass index (BMI) was ≥ 30 kg/m(2) in the Bariatric Outcomes Longitudinal Database. The %TWL computed by 100% × (pre-surgery BMI - post-surgery BMI) / pre-surgery BMI showed different trajectories depending on type of surgery...

Bariatric surgery remains the single most effective long-term treatment modality for morbid obesity, achieved mainly by lowering caloric intake through as yet ill-defined mechanisms. Here we show in rats that Roux-en-Y gastric bypass (RYGB)-like rerouting of ingested fat mobilizes lower small intestine production of the fat-satiety molecule oleoylethanolamide (OEA). This was associated with vagus nerve-driven increases in dorsal striatal dopamine release. We also demonstrate that RYGB upregulates striatal dopamine 1 receptor (D1R) expression specifically under high-fat diet feeding conditions...

BACKGROUND: Severe obesity in adolescence is associated with reduced life expectancy and impaired quality of life. Long-term benefits of conservative treatments in adolescents are known to be modest, whereas short-term outcomes of adolescent bariatric surgery are promising. We aimed to compare 5-year outcomes of adolescent surgical patients after Roux-en-Y gastric bypass with those of conservatively treated adolescents and of adults undergoing Roux-en-Y gastric bypass, in the Adolescent Morbid Obesity Surgery (AMOS) study...

INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) is considered the most common liver disease worldwide and is highly associated with obesity. The prevalences of both conditions have markedly increased in the Western civilization. Bariatric surgery is the most effective treatment for morbid obesity and its comorbidities such as NAFLD. OBJECTIVES: Measure postoperative liver fat fraction (LFF) in bariatric patients by using in-opposed-phase MRI, a widely available clinical tool validated for the quantification of liver fat METHODS: Retrospective analyses of participants, who underwent laparoscopic Roux-Y-gastric-bypass (17) or laparoscopic sleeve gastrectomy (2) were performed using magnetic resonance imaging (MRI), bioelectrical impedance analysis (BIA), and anthropometric measurements 1 day before surgery, as well as 6, 12, and 24 weeks after surgery, LFF was calculated from fat-only and water-only MR images...

INTRODUCTION: Inadequate weight loss (IWL)/weight regain (WR) and gastro-esophageal reflux disease (GERD), unresponsive to medical management, are two most common indications for conversion of sleeve gastrectomy (SG) to Roux-en-Y gastric bypass (RYGB). This study reports detailed outcomes of conversion of SG to RYGB for these two indications separately. METHODS: We interrogated our prospectively maintained database to identify patients who underwent a conversion of their SG to RYGB in our unit...
