BACKGROUND: Obesity and type 2 diabetes mellitus (T2DM) are now increasingly epidemic in Asia. As obesity and T2DM have different disease patterns in Asians compared to Westerners, outcomes after metabolic surgery may differ. The aim of this meta-analysis was to gather the current available evidence on the outcomes after metabolic surgery in Asians. METHODS: A literature search was conducted in September 2017. Four outcome measures were examined: (1) % excess weight loss (EWL), (2) post-intervention body mass index (BMI), (3) T2DM resolution or improvement, and (4) hypertension resolution...

BACKGROUND: Obesity-induced insulin resistance leads to abnormalities in glucose, lipid, and amino acid metabolism. Our study examined the differences in insulin-mediated glucose, amino acid, and lipid metabolism between morbidly obese subjects with non-obese controls and the associated changes following sleeve gastrectomy (SG). METHODS: Non-obese controls and individuals with morbid obesity and scheduled for SG were recruited. Metabolic assessments were performed for all subjects at baseline and at 6 months after SG for eight subjects...

Obesity is frequently attributed to causes such as laziness and lack of willpower and personal responsibility. The current study identified causal attributions for obesity among patients seeking bariatric surgery and compared them to those among patients seeking less invasive weight loss treatment (behavioral/pharmacological). The 16-item Causal Attributions for Obesity scale (CAO; rated 1-7) was administered to 102 patients seeking bariatric surgery (sample 1) and 178 patients seeking behavioral/pharmacological weight loss treatment (sample 2)...

Obesity, associated with increased risk of type 2 diabetes (T2D), cardiovascular disease, and hepatic steatosis et al., has become a major global health problem. Recently, obesity has been proven to be under a status of low-grade, chronic inflammation, which contributes to insulin resistance and T2D. Bariatric surgery is currently an effective treatment for the control of morbid obesity and T2D, which impels ongoing efforts to clarify physiological and molecular mechanisms mediating these benefits. The correlation between obesity, inflammation, and T2D has been revealed to a certain extent, and studies have shed light on the effect of bariatric surgery on inflammatory status of subjects with obesity...

Roux-en-Y gastric bypass, the most commonly performed procedure in bariatric surgery, still lacks a consensus on whether alimentary limb length (ALL) influences weight loss. Studies were identified by searching multiple electronic databases. Studies with enough data including body mass index (BMI) loss and percent excess weight loss (% EWL) were eligible. The statistical analysis was performed with Stata 14.0. In total, eight studies with 1714 patients were included. The meta-analysis suggested that short ALLs weakened the efficacy of Roux-en-Y gastric bypass in terms of BMI loss (standard mean deviation (SMD), - 0...

OBJECTIVES: The aim of this study was to determine the efficacy of coaching on outcome in low volume centers of excellence and to evaluate the influence of mentorship programs on the center development. BACKGROUND: The number of bariatric procedures has increased steadily in the last years. Providing nationwide bariatric care on a high professional level needs structures to train and guide upcoming centers and ensure high quality in patient care. METHODS: A prospective multicentered, observational study including laparoscopic sleeve gastrectomies (SG) and Roux-en-Y gastric bypass (RYGB) procedures was performed...

INTRODUCTION: Obesity is a serious lifestyle disease with various comorbidities and an augmented risk of cancer. Laparoscopic sleeve gastrectomy (LSG) has recently become the most popular bariatric procedure worldwide. While the cost-effectiveness is a major healthcare providers' concern, the point of histological exam of each resected tissue may be questioned. MATERIAL/METHODS: We prospectively included patients who underwent LSG. Before the surgery, gastroscopy and abdominal sonography were performed to exclude malignancies...

BACKGROUND: Despite the availability of many gastric surgery techniques to reduce obesity and its associated comorbidities, most of these procedures can result in life-threatening conditions including lifetime chronic illnesses and death. Vertical sleeve gastrectomy and Roux-en-Y gastric bypass have been reported to improve obesity-related comorbidities such as T2DM, but the long-term efficacy of these two procedures is unknown, and their significant impact on long-term weight loss was diminished by complications as reported in previous studies...

Laparoscopic sleeve gastrectomy (LSG) is the most performed surgical procedure worldwide. Long-term outcomes report that up to 30% of patients require revisional surgery and re-sleeve gastrectomy (rLSG) is one of the revisional procedures available. The aim was to update the outcomes of a cohort of rLSG at 52 months. This study reports the 52-month follow-up of a cohort of 19 patients previously published after 24-month follow-up. Sixteen patients completed the follow-up. Nine patients complained of GERD symptoms after 36 months...

BACKGROUND: Weight loss after laparoscopic sleeve gastrectomy (LSG) has been mainly attributed to the restriction of gastric volume; however; other factors may contribute to weight loss after LSG. This study aimed to investigate the correlation between the number of ghrelin-secreting cells in the gastric fundus and excess weight loss (EWL) at 12 months after LSG. METHODS: The surface area of the gastric fundus was measured postoperatively in square centimeter. Histopathologic examination of the gastric fundus was made to estimate the number of ghrelin-secreting cells per square centimeter then was multiplied by the surface area of the fundus to calculate the total number of ghrelin-secreting cells in the fundus...
