Roux-en-Y gastric bypass (RYGB) surgery is one of the most effective treatments for obesity and type II diabetes. RYGB was originally believed to work by mechanically restricting caloric intake or causing macronutrient malabsorption. However, such mechanical effects play no role in the remarkable efficacy of gastric bypass. Instead, mounting evidence shows that altered neuroendocrine signaling is responsible for the weight reducing effects of RYGB. The exact mechanism of this surgical response is still a mystery...

PURPOSE OF REVIEW: Vitamin D is essential for bone health, and may also have important functions in immunity and other systems. Vitamin D deficiency is common, and testing and supplementation is increasing. Serum vitamin D is lower in obese people; it is important to understand the mechanism of this effect and whether it indicates clinically significant deficiency. RECENT FINDINGS: Vitamin D is fat soluble, and distributed into fat, muscle, liver, and serum. All of these compartments are increased in volume in obesity, so the lower vitamin D likely reflects a volumetric dilution effect and whole body stores of vitamin D may be adequate...

BACKGROUND: A multi-component model of autonomic and enteric factors may correlate with ultimate weight loss or gain after restrictive obesity surgery. This study aimed to determine relevant parameters to predict successful long-term weight loss. METHODS: Thirty-nine patients (four males and 35 females) with a mean age of 37.2 years were followed for over 15 years after vertical banded gastroplasty. Baseline adrenergic: postural adjustment ratio (PAR) and vasoconstriction (VC); cholinergic: electrocardiogram R-to-R interval (RRI) and enteric measure: electrogastrogram (EGG) were utilized by a discriminant function analysis to classify patients as a long-term loser or gainer...

AIMS AND OBJECTIVES: To describe the experiences of patients who have failed to maintain weight loss following the insertion of a Laparoscopic Adjustable Gastric Band (LAGB) for the treatment of morbid obesity. BACKGROUND: Obesity is a global health problem resulting in physical, psychological and economic problems, and presenting challenges for health services. Surgical intervention is an increasingly common approach to treatment, however some patients do not sustain their weight loss following bariatric surgery and little is known about people's longer-term experiences following LAGB insertion...

Neurological complications are frequently recognized with weight reduction surgeries for morbid obesity. The spectrum of peripheral neuropathies complicating the weight loss surgery is wide, and among them, the acute axonal peripheral neuropathy resembling Guillain-Barre syndrome is rare and only less than a dozen cases are reported. We present three cases, which after bariatric surgery developed acute polyneuropathy that rapidly progressed over 4 weeks from the onset. All patients responded to aggressive parenteral Vitamin B1 and B12 replacement therapy...

Management of early sleeve gastrectomy leak remains challenging. The recommended approach is endoscopic stenting and abdominal drainage. Conversion to a Roux-en-Y gastric bypass (RYGB) is a common procedure used for late fistulas with distal obstruction. Here, we have presented three cases of early staple line leaks treated by conversion to RYGB. These patients had uncontrolled abdominal infections despite intensive medical treatments, and surgery was elected for abdominal drainage as well as to control the source of sepsis...

BACKGROUND: Bariatric surgery remains the most effective treatment for reducing adiposity and eliminating type 2 diabetes; however, the mechanism(s) responsible have remained elusive. Peroxisome proliferator-activated receptors (PPAR) encompass a family of nuclear hormone receptors that upon activation exert control of lipid metabolism, glucose regulation and inflammation. Their role in adipose tissue following bariatric surgery remains undefined. MATERIALS AND METHODS: Subcutaneous adipose tissue biopsies and serum were obtained and evaluated from time of surgery and on postoperative day 7 in patients randomized to Roux-en-Y gastric bypass (n=13) or matched caloric restriction (n=14), as well as patients undergoing vertical sleeve gastrectomy (n=33)...

BACKGROUND/OBJECTIVES: Despite the effectiveness of bariatric surgery, there is still substantial variability in long-term weight outcomes and few factors with predictive power to explain this variability. Neuroimaging may provide a novel biomarker with utility beyond other commonly used variables in bariatric surgery trials to improve prediction of long-term weight-loss outcomes. The purpose of this study was to evaluate the effects of sleeve gastrectomy (SG) on reward and cognitive control circuitry postsurgery and determine the extent to which baseline brain activity predicts weight loss at 12-month postsurgery...

AIMS: The gut hormone peptide tyrosine tyrosine (PYY) is critical for maintaining islet integrity and restoring islet function following Roux-en-Y gastric bypass (RYGB). The expression of PYY and its receptors (NPYRs) in islets has been documented but not fully characterized. Modulation of islet PYY by the proteolytic enzyme DPP-IV has not been investigated and the impact of DPP-IV inhibition on islet PYY function remains unexplored. Here we have addressed these gaps and their effects on glucose-stimulated insulin secretion (GSIS)...

Obesity has reached epidemic proportions and to date, bariatric surgery remains the only effective treatment for morbid obesity in terms of its capacity to achieve durable weight loss. Bariatric surgery procedures, including Roux-en-Y gastric bypass (RYGB), adjustable gastric banding (AGB) and sleeve gastrectomy (SG) have been the primary procedures conducted over the past decade, with SG increasing in popularity over the past five years at the expense of both RYGB and AGB. Although these procedures were initially proposed to function via restrictive or malabsorptive mechanisms, it is now clear that profound physiological changes underlie the metabolic improvements in patients who undergo bariatric surgery...

BACKGROUND: Frailty assessment can help vascular surgeons predict perioperative risk and long term mortality for their patients. Unfortunately, comprehensive frailty assessments take too long to integrate into clinic workflow. This study was designed to evaluate 2 rapid methods for assessing frailty during vascular clinics-a short patient-reported survey and a provider-reported frailty scale. METHODS: We prospectively enrolled 159 patients presenting to an academic medical center vascular surgery clinic between May-November 2016...

Obesity is a public health epidemic associated with a number of comorbidities, most notably type 2 diabetes and hypertension, as well as elevated all-cause mortality. The treatment for obesity and its associated comorbidities has most recently expanded into the field of bariatric endoscopy. This field bridges a gap between lifestyle counseling with or without pharmaceutical treatment and the most effective treatment of obesity, bariatric surgery. Because of its minimally invasive nature, bariatric endoscopic therapy has the potential to appeal to the large sector of the obese population that resists surgery, as well as those early in the onset of obesity...

BACKGROUND: Obesity is a disease that is caused by genetic and environmental factors. However, epigenetic mechanisms of obesity are less well known. DNA methylation provides a mechanism whereby environmental factors can influence gene transcription. The aim of our study was to investigate skeletal muscle DNA methylation of sorbin and SH3 domain containing 3 (SORBS3) with weight loss induced by Roux-en-Y gastric bypass (RYGB). RESULTS: Previously, we had shown increased methylation (5...

The aim of this meta-analysis was to determine the feasibility of laparoscopic gastrectomy (LG) for elderly gastric cancer patients by comparing laparoscopic and conventional open gastrectomies (OG). Comprehensive search of the PubMed, EMBASE, and Cochrane Library databases revealed nine non-randomized controlled studies that compared LG and OG in elderly gastric cancer patients We then analyzed dichotomous or continuous parameters using odds ratios (ORs) or weighted mean differences (WMDs). Overall survival was estimated using hazard ratios (HRs) with a fixed effects or random effects model...
