Outcomes After Metabolic Surgery in Asians —a Meta-analysis
ConclusionRYGB results in better weight loss compared to SG in Asians, but the rate of T2DM resolution/improvement and improvement of hypertension appears to be similar. In Asian patients without symptoms of gastro-esophageal reflux disease in whom metabolic surgery is performed mainly for T2DM and metabolic syndrome, SG may be the surgery of choice.

Laparoscopic Sleeve Gastrectomy Learning Curve: Clinical and Economical Impact
AbstractBackgroundThe results in the literature regarding the learning curve (LC) of laparoscopic sleeve gastrectomy (LSG) are scarce and non-definitive. The purpose of the study was to evaluate the correlation between the LSG learning curve and intraoperative parameter variation, postoperative morbidity, weight loss results, and economic impact.MethodsThe first 99 obese patients undergoing LSG surgery by the same surgeon from March 2013 to April 2016 were included in the present study. Patients were equally distributed among three groups (A, B, C) based on case sequence.ResultsThe three study groups were homogeneous with ...

Causal Attributions for Obesity Among Patients Seeking Surgical Versus Behavioral/Pharmacological Weight Loss Treatment
AbstractObesity 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). Between-subjects analyses compared CAO ratings for the two samp...

More than an Anti-diabetic Bariatric Surgery, Metabolic Surgery Alleviates Systemic and Local Inflammation in Obesity
AbstractObesity, 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 li...

Macroscopic Evaluation of Gastric Specimens After Laparoscopic Sleeve Gastrectomy —an Optimum Screening Test for Incidental Pathologies?
AbstractIntroductionObesity 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/MethodsWe prospectively included patients who underwent LSG. Before the surgery, gastroscopy and abdominal sonography were performed to exclude malignancies. The gastric specimen was cut open after the surgery and inspected macroscopically, then...

Whether a Short or Long Alimentary Limb Influences Weight Loss in Gastric Bypass: a Systematic Review and Meta-Analysis
AbstractRoux-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), &mi...

Pilot Study of a New Model of Bariatric Surgery: Laparoscopic Intestinal Bipartition —Safety and Efficacy Against Metabolic Disorders
AbstractBackgroundDespite 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. Recently, laparoscopic biliopancreatic diversion with duodenal switch (B...

Re-sleeve Gastrectomy 4  Years Later: Is It Still an Effective Revisional Option?
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. Five patients were converted to laparoscopic RYGB. Two patients were con verted to a laparoscopic BPD-DS for weight regain 4 patients are asymptomatic with stable weight. On the basis of our disappointing results, it can be said that rLSG is not currently offered as revisional procedure in both centers. (Source: Obesity Surgery)

Robotic Versus Laparoscopic Roux-en-Y Gastric Bypass for Morbid Obesity: a Systematic Review and Meta-Analysis
AbstractWe aim to summarize the existing evidence to compare the surgical outcomes of robotic Roux-en-Y gastric bypass (RRYGB) and laparoscopic RYGB (LRYGB) and to determine if these two procedures are equivalent. Literature searches were conducted by a comprehensive search in PubMed, EMBASE, and the Cochrane Library. Nineteen articles met the inclusion criteria for this review. The robotic and laparoscopic procedures had no significant differences in hospitalization time, conversion, reoperation, readmission, and postoperative complications. However, RRYGB was associated with a longer mean operative time. RRYGB was not fo...

Short-Term Impact of Bariatric Surgery on Best-Corrected Distance Visual Acuity and Diabetic Retinopathy Progression
We present 3-year changes in the best-corrected visual acuity and DR grade in a retrospective observational study of 32 morbidly obese patients (64 eyes) who underwent Roux-en-Y-gastric bypass surgery. We found that despite overall benefits in vision, there was an initial progression from no retinopathy to background retinopathy in 18.9% and 21.7% at years 1 and 2 respectively. Patients with pre-proliferative DR at baseline were at increased risk of developing sight-threatening DR.

The Efficacy of Energy-Restricted Diets in Achieving Preoperative Weight Loss for Bariatric Patients: a Systematic Review
This study examined the efficacy of preoperative diets in achieving 5% weight loss. From a systematic literature search, eight randomised controlled trials (n = 862) were identified. Half of the trials used a “very-low-calorie diet” whilst the rest employed a “low-calorie diet”. Only five diets achieved ≥ 5% weight loss over varying durations and energy intakes. By inference, compliance with a 700–1050 kcal (2929–4393 kJ) diet, consi sting of moderate carbohydrate, high protein and low/moderate fat, for 3 weeks is likely to achieve 5% weight loss.
