Elin Rebecka Carlsson, Josefine Liv Gilling Grundtvig, Sten Madsbad, Mogens Fenger
Metabolic surgery is superior to lifestyle intervention in reducing weight and lowering glycemia and recently suggested as treatment for type 2 diabetes mellitus. Especially Roux-en-Y gastric bypass (RYGB) has been focus for much research, but still the mechanisms of action are only partly elucidated. We suggest that several mechanisms might be mediated by sphingolipids like sphingomyelin. We measured serum sphingomyelin before and up to 2 years after RYGB surgery in 220 patients, divided before surgery in one non-diabetic subgroup and two diabetic subgroups, one of which contained patients obtaining remission of type 2 diabetes after RYGB, while patients in the other still had diabetes after RYGB...

Background: Fetuin-A and leukocyte cell-derived chemotaxin-2 (LECT-2) are liver-derived proteins. Fetuin-A is an independent risk factor for type 2 diabetes (T2D) and obese patients with T2D have higher plasma fetuin-A levels than those without T2D. LECT-2 has positive correlation with the severity of both obesity and insulin resistance. The changes in plasma fetuin-A are not consistent after bariatric surgery and no studies have investigated the changes in LECT-2 on the obese patients with T2D after bariatric surgery...

BACKGROUND/AIMS: Type 2 diabetes mellitus (T2DM) is considered a chronic progressive incurable metabolic disease. Single-anastomosis gastric bypass (SAGB) has proved to be effective in obese patients, yet its impact on non-obese diabetics is not extensively studied. The aim is to determine the anthropometric and glycemic outcomes of SAGB as a proposed line of treatment for T2DM patients with body mass index (BMI) 25-30 kg/m2 . METHODS: From November 2013 to March 2016, a prospective study has been conducted at Ain-Shams University Hospitals on 17 consecutive patients who have undergone SAGB...

Bariatric surgery is effective in treating different components of metabolic syndrome including obesity, type 2 diabetes mellitus (T2DM), and hyperlipidemia. But there is no consensus on the ideal biliopancreatic and Roux limb length. This study aimed to explore the effect of biliopancreatic limb and Roux limb lengths during laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures on weight loss and T2DM control.We studied the clinical records of 58 patients with metabolic syndrome, T2DM, and body mass index (BMI) 32 to 50 kg/m who underwent LRYGB in our hospital...

Obesity and its associated comorbidities have become one of the largest challenges for health care in the near future. Conservative therapy for obesity and related comorbidities have a very high failure rate and poor long-term results. Similarly, the conservative and medical management of the majority of metabolic diseases such as type 2 diabetes mellitus are only able to slow down disease progression but have no causal effect on the disease process. Obesity surgery has evolved as a highly effect therapy for severe obesity achieving long-lasting weight loss...

Type 2 diabetes mellitus (T2DM) is a chronic progressive disease, which manifests as an endocrine disorder. Among the different methods of surgery available to treat patients with T2DM, Roux-en-Y gastric bypass (RYGBP) and ileal transposition (IT) are the most commonly performed. The aim of the present study was to investigate the effects of RYGBP combined with IT on rats with T2DM. A total of 8 healthy male rats were used as a control group and 40 GK rats were randomly divided into 5 groups: A diabetes mellitus (DM) group, a sham operative group (SO), a RYGBP group, an IT group and a RYGBP+IT group...

Obesity is a worldwide epidemic often complicated by multiple comorbidities, including type 2 diabetes mellitus (T2DM). Bariatric surgery is an increasingly common and effective weight-loss strategy for obese patients that may result in resolution of metabolic-related disease states, such as T2DM. Although bariatric surgery has many positive outcomes for patients, dietary and pathophysiologic changes can create difficult-to-control blood glucose, especially in the immediate perioperative setting. Depending on oral antidiabetic agent and insulin needs preoperatively, many patients require cessation of oral agents and reduction or cessation of insulin...

Type 2 diabetes mellitus (T2DM) is a metabolic disorder associated with obesity and hyperglycemia. Roux-en-Y gastric bypass (RYGB) surgery is a common treatment for severely obese patients and T2DM. Both RYGB and T2DM are linked to increased skeletal fragility, though the exact mechanisms are poorly understood. Our aim was to characterize the structural, mechanical and compositional properties of bones from diet-induced obese and RYGB-treated obese (bypass) mice to elucidate which the exact factors are contributing to the increased skeletal fragility...

Bariatric surgery is an effective treatment for morbid obesity and its metabolic related comorbidities; type 2 diabetes, hypertension and hyperlipidaemia.1 However, the literature is scarce regarding the long-term outcome after bariatric surgery, especially among multi-ethnic Asian populations. Considering the growing number of bariatric metabolic surgeries in Asia, we have attempted to provide a regional perspective on 5-year long-term clinical outcomes post bariatric surgery in Singapore. Between 2010 and 2016, all bariatric operative cases were included, and these comprised: laparoscopic sleeve gastrectomy (LSG), 393; laparoscopic Roux-En-Y gastric bypass (RYGB), 125; laparoscopic mini-gastric bypass (MGB), 43...

AIMS/HYPOTHESIS: In this prospective case-control study we tested the hypothesis that, while long-term improvements in insulin sensitivity (SI ) accompanying weight loss after Roux-en-Y gastric bypass (RYGB) would be similar in obese individuals with and without type 2 diabetes mellitus, stimulated-islet-cell insulin responses would differ, increasing (recovering) in those with diabetes but decreasing in those without. We investigated whether these changes would occur in conjunction with favourable alterations in meal-related gut hormone secretion and insulin processing...
