Abstract
BACKGROUND The influence of metabolic surgery on the glucose and lipid profiles of nonobese body mass index<30 kg/m2 patients with type 2 diabetes, particularly the effect ≥1 year, remains unknown. METHODS PubMed and Ovid Embase were used. SETTING University hospitals. RESULTS In total, 21 studies including 921 patients were examined in this systematic review, the results of which revealed decrease in body mass index, waist circumference, fasting plasma glucose, glycosylated hemoglobin A1C, fasting C-peptide, fasting insulin, homeostasis model of assessment for insulin resistance index, triglycerides, total cholesterol, and low-density lipoprotein cholesterol. An increase in high-density lipoprotein cholesterol was also observed. The diabetes remission rates ranged from 13.3% to 90.2% according to 20 studies. The incidence of gastrointestinal bleeding ranged from 1% to 10% according to 9 studies. Four studies reported anemia after Roux-en-Y gastric bypass or one-anastomosis gastric bypass, with the incidence ranging from 8% to 33%. CONCLUSIONS Nonobese patients can achieve improvements in weight-related indices and glucose and lipid profiles in the short and medium term after metabolic surgery; however, the complications of metabolic surgery warrant further attention.

Abstract
BACKGROUND The National Bariatric Surgery Registry (NBSR) is the largest bespoke database in the field in the United Kingdom. OBJECTIVES Our aim was to analyze the NBSR to determine whether the effects of obesity surgery on associated co-morbidities observed in small randomized controlled clinical trials could be replicated in a "real life" setting within U.K. healthcare. SETTING United Kingdom. METHODS All NBSR entries for operations between 2000 and 2015 with associated demographic and co-morbidity data were analyzed retrospectively. RESULTS A total of 50,782 entries were analyzed. The patients were predominantly female (78%) and white European with a mean age of 45 ± 11 years and a mean body mass index of 48 ± 8 kg/m2. Over 5 years of follow-up, statistically significant reductions in the prevalence of type 2 diabetes, hypertension, dyslipidemia, sleep apnea, asthma, functional impairment, arthritis, and gastroesophageal reflux disease were observed. The "remission" of these co-morbidities was evident 1 year postoperatively and reached a plateau 2 to 5 years after surgery. Obesity surgery was particularly effective on functional impairment and diabetes, almost doubling the proportion of patients able to climb 3 flights of stairs and halving the proportion of patients with diabetes related hyperglycemia compared with preoperatively. Surgery was safe with a morbidity of 3.1% and in-hospital mortality of .07% and a reduced median inpatient stay of 2 days, despite an increasingly sick patient population. CONCLUSIONS Obesity surgery in the U.K. results not only in weight loss, but also in substantial improvements in obesity-related co-morbidities. Appropriate support and funding will help improve the quality of the NBSR data set even further, thus enabling its use to inform healthcare policy.

Abstract
Several bariatric operations originally designed to promote weight loss have been found to powerfully treat type 2 diabetes, causing remission in most cases, through diverse mechanisms additional to the secondary consequences of weight loss. These observations have prompted consideration of such operations as 'metabolic surgery', used expressly to treat diabetes, including among patients who are only mildly obese or merely overweight. Large, long-term observational studies consistently demonstrate that bariatric/metabolic surgery is associated with reductions in all cardiovascular risk factors, actual cardiovascular events, microvascular diabetes complications, cancer and death. Numerous recent randomised clinical trials, directly comparing various surgical vs non-surgical interventions for diabetes, uniformly demonstrate the former to be superior for improvements in all glycaemic variables, as well as other metabolic endpoints. These benefits are similar among individuals with type 2 diabetes and a preoperative BMI of 30-35 kg/m2 compared with traditional bariatric surgery patients with a BMI >35 kg/m2. The safety profiles of modern laparoscopic bariatric/metabolic operations are similar to those of elective laparoscopic hysterectomy and knee arthroplasty. However, more evidence regarding the risks, benefits and costs of surgery is needed from very long-term (>5 year) randomised clinical trials powered to observe 'hard' clinical endpoints following the operations most commonly used today. Given the efficacy, safety and cost-effectiveness of metabolic surgery, the second Diabetes Surgery Summit (DSS-II) consensus conference recently placed surgery squarely within the overall diabetes treatment algorithm, recommending consideration of this approach for patients with inadequately controlled diabetes and a BMI as low as 30 kg/m2, or 27.5 kg/m2 for Asian individuals. These new guidelines have been formally ratified by 53 leading diabetes and surgery societies worldwide. Given this broad level of endorsement, we feel that the DSS-II recommendations should now replace the outdated National Institutes of Health (NIH) suggestions that have governed bariatric surgery practice and insurance compensation worldwide since 1991.

Abstract
Bariatric surgery is very effective in achieving and maintaining weight loss but it is also associated with improvement of obesity metabolic complications, primarily type 2 diabetes (T2D). Remission of T2D or at least a net improvement of glycemic control persists for at least 5 years. The bypass of duodenum and of the first portion of the jejunum up to the Treitz ligament as in Roux-en-Y Gastric Bypass (RYGB), or the bypass of the duodenum, the entire jejunum and the first tract of the ileum, such as in Bilio-Pancreatic Diversion (BPD), achieve different results on insulin sensitivity. Insulin resistance is the major driver of T2D manifesting long before insulin secretion failure. In fact, T2D development can be prevented by treatment with insulin sensitizing agents. Interestingly, RYGB improves hepatic insulin sensitivity while BPD ameliorates whole-body insulin sensitivity. Two major theories have been advocated to explain the early remission of T2D following RYGB or BPD before a meaningful weight loss takes place, the foregut and the hindgut hypotheses. The former holds that the bypass of the proximal intestine, i.e. duodenum and jejunum, prevents the secretion of signals - including nervous transmitters and hormones - promoting insulin resistance, the latter instead states that the delivery of nutrients directly into the ileum stimulates the secretion of hormones improving glucose disposal. The most studied candidate is Glucagon Like Peptide 1 (GLP1). However, while there is unambiguous evidence that GLP-1 stimulates insulin secretion, its direct action in lowering insulin resistance, independently of the effect on weight loss secondary to its satiety action, is utterly controversial. In this review we examine the effects on T2D and gastrointestinal peptide secretion produced by different types of metabolic surgery and by minimally invasive endoscopic surgery, whose utilization for the treatment of obesity and T2D is gaining wider interest and acceptance.

Abstract
Weight loss surgery, also referred to as bariatric surgery, has been in existence since the 1950's. Over the decades, it has been demonstrated to successfully achieve meaningful and sustainable weight loss in a large number of patients who undergo these procedures. Additionally, the benefits observed across a number of metabolic disorders such as type 2 diabetes mellitus and hyperlipidemia, are often to a degree, independent of the weight loss, thus the term "metabolic bariatric surgery (MBS)" has become a better descriptor. Throughout its long history, MBS has evolved from an era of high morbidity and mortality to one of laudable safety despite the high-risk nature of the patients undergoing these major gastrointestinal procedures. This article will describe the historic evolution of MBS and concentrate on those events that were instrumental in reducing the morbidity of these operations.

Abstract
BACKGROUND AND AIM Swedish health registries are common sources of data for studies on the effects of obesity surgery, and there is a need to assess the quality of data in these registries. The aim of this study was to validate the registration of obesity surgery in the National Patient Registry (NPR) and the Scandinavian Obesity Surgery Registry (SOReg). METHOD We randomly selected 962 out of 8501 registrations of obesity surgery in 2011 from the NPR and SOReg. Registered surgical procedures in the NPR and SOReg were compared to the medical records, and concordance was analyzed by calculating positive predictive value (PPV) with 95 % confidence interval (CI). RESULTS We received 938 (98 %) medical records for manual review. The overall PPV for obesity surgery was high in the NPR (PPV 97.0; 95 % CI 95.6-98.4) and even higher in SOReg (PPV 99.7; 95 % CI 99.3-100). Accuracy was higher for gastric bypass surgery than for other types of obesity surgery. Registrations that were misclassified as obesity surgery (n = 44) included reoperations due to complications or reconstruction to normal anatomy after previous obesity surgery (n = 11) and endoscopic procedures (n = 10). CONCLUSION Obesity surgery registrations in the NPR and SOReg have high accuracy and are reliable sources of data to identify patients having undergone obesity surgery. When it is of importance to distinguish between specific surgical procedures, non-gastric bypass surgeries in the NPR should ideally be supplemented with data from other sources.

Abstract
Background Idiopathic intracranial hypertension (IIH) is associated with obesity and weight loss by any means is considered beneficial in this condition. Objectives This study aims to appraise bariatric surgery vs. non-surgical weight-loss (medical, behavioural and lifestyle) interventions in IIH management. Methods A systematic review and meta-analyses of surgical and non-surgical studies. Results Bariatric surgery achieved 100% papilloedema resolution and a reduction in headache symptoms in 90.2%. Non-surgical methods offered improvement in papilloedema in 66.7%, visual field defects in 75.4% and headache symptoms in 23.2%. Surgical BMI decrease was 17.5 vs. 4.2 for non-surgical methods. Conclusions Whilst both bariatric surgery and non-surgical weight loss offer significant beneficial effects on IIH symptomatology, future studies should address the lack of prospective and randomised trials to establish the optimal role for these interventions.

Abstract
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. Recent research suggests that changes in the concentrations of plasma bile acids might contribute to these metabolic changes after surgery. In this review, we aimed to outline the potential role of bile acids in SWRD. We systematically reviewed MEDLINE, SCOPUS, and Web of Science for articles reporting the effect of SWRD on outcomes published between 1969 and 2016. We found that changes in circulating bile acids after surgery may play a major role through activation of the farnesoid X receptor A (FXRA), the fibroblast growth factor 19 (FGF19), and the G protein-coupled bile acid receptor (TGR5). Bile acid concentration increased significantly after RYGB. Some studies suggest that a transitory decrease occurs at 1 week post-surgery, followed by a gradual increase. Most studies have shown the increase to be proportionate by all bile acid subtypes. Bile acids can regulate glucose metabolism through the expression of TGR5 receptor in L cells, resulting in a release of glucagon-like peptide 1 (GLP-1). It may also induce the synthesis and secretion of FGF19 in ileal cells, thereby improving insulin sensitivity and regulating glucose metabolism. All the present SWRD are involved with changes in food stimulation to the stomach. This implies that discovering and developing the antagonists to TGR5 and FXRA may effectively control metabolic syndrome and the elucidation of the mechanisms underlying the physiological effects related to weight loss and T2D remission after surgery may help to identify new drug targets.

Abstract
BACKGROUND The number of bariatric procedures performed in Japan is increasing. There are isolated reports of bariatric surgery, but there have been no nationwide surveys including long-term data. METHODS We retrospectively reviewed data for patients who underwent bariatric and metabolic surgery throughout Japan and reviewed outcomes. Surveys were sent to ten institutions for number of procedures, preoperative patient weight and preoperative obesity-related comorbidities, and data at 1, 3, and 5 years postoperatively. Improvement of type 2 diabetes mellitus at 3 years after surgery was stratified by baseline ABCD score, based on age, body mass index, C-peptide level, and duration of diabetes. RESULTS Replies were received from nine of the ten institutions. From August 2005 to June 2015, 831 patients, including 366 males and 465 females, underwent bariatric procedures. The mean age was 41 years, and mean BMI was 42 kg/m2. The most common procedure was laparoscopic sleeve gastrectomy (n = 501, 60 %) followed by laparoscopic sleeve gastrectomy with duodenojejunal bypass (n = 149, 18 %). Laparoscopic Roux-en-Y gastric bypass was performed in 100 patients (12 %), and laparoscopic adjustable gastric banding was performed in 81 (10 %). At 3 years postoperatively, the remission rate of obesity-related comorbidities was 78 % for diabetes, 60 % for hypertension, and 65 % for dyslipidemia. Patients with complete remission of diabetes at 3 years postoperatively had a higher ABCD score than those without (6.4 ± 1.6 vs 4.2 ± 2.0, P < 0.05). CONCLUSIONS Bariatric and metabolic surgery for Japanese morbidly obese patients is safe and effective. These results are comparable with the results of previous studies.

Abstract
BACKGROUND Obesity has become one of the greatest public health concerns worldwide and is known to be the most important risk factor for obstructive sleep apnoea (OSA). Prevalence of OSA has increased over the last two decades, but it is estimated that the majority of cases still remain undiagnosed. The aim of this study was to investigate the prevalence of OSA in Finnish bariatric surgery candidates. METHODS In this prospective multicentre study, standard overnight cardiorespiratory recording was conducted in 197 consecutive patients from three different hospitals. A sleep questionnaire was also administered. Anthropometric and demographic measurements included age, weight, body mass index (BMI) and waist and neck circumference. RESULTS Altogether, 71 % of the patients were diagnosed with OSA. The prevalence was higher in males (90 %) than in females (60 %) (p < 0.001). In OSA patients' group, the mean neck and waist circumference was larger (p < 0.001) and the body weight higher (p < 0.01) than in non-OSA group. When separating patients by gender, a significant difference remained only concerning neck circumference in female patients. CONCLUSIONS OSA is very common among bariatric surgery patients, especially in men. Considering this and the increased long-term morbidity and mortality generally related to OSA, a routine screening for OSA seems indicated in bariatric patients, particularly men.

Abstract
BACKGROUND While it is well established that Roux-en-Y gastric bypass (RYGB) causes a rapid and heightened peak blood alcohol concentration (BAC), results from previous studies on the effects of sleeve gastrectomy (SG) on alcohol pharmacokinetics are conflicting. Data from 2 studies found SG did not affect BAC, whereas another study found SG caused a heightened peak BAC after alcohol ingestion. Moreover, these 3 studies estimated BAC from breathalyzers, which might not reliably estimate peak BAC. OBJECTIVES The aims of this study were to evaluate (1) the effect of SG, relative to RYGB and a presurgery group, on alcohol pharmacokinetics and subjective effects, and (2) whether breathalyzers are reliable in this population. SETTING Single-center prospective nonrandomized trial. METHODS We performed alcohol challenge tests in 11 women who had SG surgery 1.9 ± .1 years ago (body mass index = 35.1 ± 6.6 kg/m2), 8 women who had RYGB surgery 2.2 ± .4 years ago (body mass index = 30.0 ± 5.2 kg/m2), and 9 women who were scheduled for bariatric surgery (body mass index = 44.1 ± 4.0 kg/m2). BACs were estimated from breath samples and measured by gas chromatography at various times after consuming approximately 2 standard drinks. RESULTS BAC increased faster, peak BAC was approximately 2-fold higher, and feelings of drunkenness were heightened in both SG and RYGB groups relative to the presurgery group (P values<.001). BAC estimated from breath samples underestimated BAC by 27% (standard deviation = 13%) and missed peak BACs postsurgery. CONCLUSIONS SG, similar to RYGB, causes marked alterations in the response to alcohol ingestion manifested by a faster and higher peak BAC. The breathalyzer is invalid to assess effects of gastric surgeries on pharmacokinetics of ingested alcohol.

Abstract
BACKGROUND Recent studies have suggested that metabolic surgery reduces cancer risk. This study aims to determine if incident cancer is associated with the extent of weight loss after Roux-en-Y gastric bypass (RYGB). METHODS Patients at a large tertiary bariatric surgery center were retrospectively reviewed to identify patients with no history of cancer at the time of RYGB. Diagnoses in the electronic health record, a tumor registry, and chart review were used to identify postoperative incident solid organ cancer. The overall incidence of organ cancer was estimated using Kaplan-Meier analysis. The percent total body weight loss (%TWL) in the 48 months after surgery but prior to cancer was compared between those that developed organ cancer versus those that did not using repeated measures linear regression. RESULTS The 2943 patients had a mean age of 45.6 years (SD = 11.1), 81 % were female, and a mean baseline body mass index (BMI) of 47.2 kg/m2 (SD = 7.9). Median follow-up after surgery was 3.8 years (range = [<1, 12]). Incident organ cancer developed and was verified in 54 of the 2943 patients (1.8 %). Kaplan-Meier estimates for cancer at 3, 5, and 10 years postsurgery were 1.3, 2.5, and 4.2 %. After adjusting for age, BMI, sex, diabetes, hypertension, and dyslipidemia, patients that developed organ cancer achieved less weight loss (-1.5 % TWL, 95 % CI = [-2.9 %, -0.1 %], p = 0.034). CONCLUSIONS Greater weight loss after metabolic surgery may be associated with lower organ cancer risk.

Abstract
There is mounting evidence, derived from mechanistic studies, RCTs, and other high-quality studies that there are weight loss independent antidiabetic effects of gastrointestinal surgery. Additionally, there appears to be no relation between the positive metabolic outcomes to baseline BMI. The outdated US National Health Institutes guidelines from 1991 were centered on BMI only criterion and often misleading. The Second Diabetes Surgery Summit held in collaboration with leading diabetes organizations and endorsed by a large group of international Professional Societies developed guidelines that defined eligibility based on the severity and degree of T2D medical control while referring to obesity as a qualifier and not the sole criterion. That is the first time that guidelines are provided to put metabolic surgery into the T2D treatment algorithms.

Abstract
PURPOSE OF REVIEW Non-alcoholic fatty liver disease (NAFLD) is frequently associated with obesity and overweight. It has a broad spectrum of clinical and histological presentations, such as steatosis, inflammation (known as non-alcoholic steatohepatitis or NASH), fibrosis, and cirrhosis. There is increasing evidence that marked weight loss following bariatric surgery is associated with NASH resolution; however, little is known about the mechanisms that may lead to this beneficial condition and if it is due to weight loss alone. In this review, the authors present the latest data regarding NASH resolution following metabolic surgery and try to answer the following questions: is NASH resolution due to weight loss alone or is it related to weight-independent effects similarly to T2D? In such case, can NASH be considered as a sole criterion for metabolic surgery? RECENT FINDINGS Most data evaluating NAFLD and bariatric and metabolic surgery are derived from cohort studies. Available data are extremely variable, but in general show a dramatic regression of steatosis, inflammatory changes, and in some cases even fibrosis that is probably linked to major weight loss following surgery. There are no randomized controlled trials evaluating the effects of metabolic surgery over NASH vs. lifestyle modifications. To consider NASH a sole indication for metabolic surgery regardless of BMI, such studies are desperately needed and should be the primary focus of future research in metabolic surgery.

Abstract
PURPOSE OF REVIEW Preoperative weight loss regimens prior to bariatric surgery have been a routine and common practice for many centers, in the US and around the world. The mandated participation in such programs has largely been influenced by loco-regional payer requirements. The relationship between adherence to a mandatory weight loss regimen and achieved preoperative weight loss as well as the clinical impact of preoperative weight loss on bariatric outcomes remains uncertain. RECENT FINDINGS This review examines the available current literature, in the context of previous findings, regarding the impact of mandated preoperative weight loss regimens and mandatory weight loss on bariatric outcomes. The reviewed studies do not provide sufficient evidence that mandatory participation in a preoperative weight loss regimen prior to bariatric surgery is associated with achieved weight loss or durable bariatric outcome benefit. Preoperative weight loss, when achieved, may confer a positive benefit on postoperative complications; however, this is not a consistent finding in the literature and requires further validation. The practice of mandating participation in a preoperative weight loss regimen or requiring mandatory weight loss prior to bariatric surgery is not supported by current literature and may serve as an obstacle to medically necessary and potentially life-saving treatment.

Abstract
BACKGROUND Mild obesity (BMI 30-34.9 kg/m2) is highly prevalent worldwide and is associated with type 2 diabetes mellitus. The efficacy of bariatric surgery remains unclear, including among Mexicans. The criteria for diabetes remission are inconsistent, as they are based on different thresholds for glycated hemoglobin, with remission rates ranging from 43 to 73%. METHODS Mildly obese patients with type 2 diabetes mellitus who underwent laparoscopic gastric bypass were prospectively analyzed. The primary objective was to determine the impact of surgery on their metabolic profiles. Demographic, clinical, and biochemical parameters were measured at baseline and at 3, 6, 9, 12, and 18 months. Diabetes remission rate was defined as an HbA1c <5.7%. Complications within 30 days and weight loss (% total weight loss) were also analyzed. RESULTS Twenty-three Mexican patients underwent surgery. Of the 19 patients, evaluable at 18 months, nine (47.4%) achieved complete diabetes remission, seven (36.8%) showed partial remission, and three (15.8%) showed improvement. Significant improvements in lipid profile, cardiovascular risk, blood pressure, and every metabolic parameter were observed, beginning at the first month and throughout the study. The final total percentage weight loss was 24.9%. Three patients (13%) experienced complications, but none required reoperation or died. CONCLUSION Laparoscopic gastric bypass is a safe and effective method to improve the metabolic profile of mildly obese Mexican patients with type 2 diabetes mellitus, inducing high remission rates even when the strictest model is used.

Abstract
Bariatric surgery is emerging as a powerful weapon against severe obesity and type 2 diabetes mellitus (T2DM). Given its role in metabolic regulation, the gastrointestinal tract constitutes a meaningful target to treat T2DM, especially in light of accumulating evidence that surgery with gastrointestinal manipulations may result in T2DM remission (metabolic surgery). The major mechanisms mediating the weight loss-independent effects of bariatric surgery comprise effects on tissue-specific insulin sensitivity, β-cell function and incretin responses, changes in bile acid composition and flow, modifications of gut microbiota, intestinal glucose metabolism and increased brown adipose tissue metabolic activity. Shorter T2DM duration, better preoperative glycemic control and profound weight loss, have been associated with higher rates of T2DM remission and lower risk of relapse. In the short and medium term, a significant amount of weight is lost, T2DM may completely regress, and cardiometabolic risk factors are dramatically improved. In the long term, metabolic surgery may achieve durable weight loss, prevent T2DM and cancer, improve overall glycemic control while leading to significant rates of T2DM remission, and reduce total and cause-specific mortality. The gradient of efficacy for weight loss and T2DM remission comparing the four established surgical procedures is biliopancreatic diversion >Roux-en-Y gastric bypass >sleeve gastrectomy >laparoscopic adjustable gastric banding. According to recently released guidelines, bariatric surgery should be recommended in diabetic patients with class III obesity, regardless of their level of glycemic control, and patients with class II obesity with inadequately controlled T2DM despite lifestyle and optimal medical therapy. Surgery should also be considered in patients with class I obesity and inadequately controlled hyperglycemia despite optimal medical treatment.

Abstract
Bariatric surgery, specifically Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG), are the most effective and durable treatments for morbid obesity and potentially a viable treatment for type 2 diabetes (T2D). The resolution rate of T2D following these procedures is between 40 and 80% and far surpasses that achieved by medical management alone. The molecular basis for this improvement is not entirely understood, but has been attributed in part to the altered enterohepatic circulation of bile acids. In this review we highlight how bile acids potentially contribute to improved lipid and glucose homeostasis, insulin sensitivity and energy expenditure after these procedures. The impact of altered bile acid levels in enterohepatic circulation is also associated with changes in gut microflora, which may further contribute to some of these beneficial effects. We highlight the beneficial effects of experimental surgical procedures in rodents that alter bile secretory flow without gastric restriction or altering nutrient flow. This information suggests a role for bile acids beyond dietary fat emulsification in altering whole body glucose and lipid metabolism strongly, and also suggests emerging roles for the activation of the bile acid receptors farnesoid x receptor (FXR) and G-protein coupled bile acid receptor (TGR5) in these improvements. The limitations of rodent studies and the current state of our understanding is reviewed and the potential effects of bile acids mediating the short- and long-term metabolic improvements after bariatric surgery is critically examined.

Abstract
Bariatric/metabolic surgery has proven to be effective in inducing and maintaining diabetes remission-although with a percentage of patients undergoing hyperglycemia relapse-weight loss, and improvement of the cardiovascular risk. It is, however, associated with mortality, although low, and early and late complications. In particular, metabolic complications are related to vitamin deficiency due to the erratic absorption of the supplemented vitamins and to the unpredictable compliance of patients to vitamin and trace element supplementation. In addition, often, the general practitioners and even the specialists are unaware of the clinical effects of metabolic dysfunction following malabsorptive surgery. The choice of the surgical procedure should be the balance between benefits and risks. Our review addresses this important question trying to give some suggestions.

Abstract
Obesity and hypertension are growing epidemics in the modern world. Lifestyle changes and medical treatment for obesity have disappointing long-term results and albeit drugs for hypertension are usually very effective, the necessity of multiple pills and frequent side effects make the adherence to treatment a huge challenge for healthcare systems. Bariatric/metabolic surgery is a very effective treatment and an exponential number of studies have been showing its positive impact beyond weight loss, mainly on type 2 diabetes. There is also growing evidence suggesting that bariatric/metabolic surgery is associated with reduced incidence of cardiovascular events, but the impact on hypertension and other components of metabolic syndrome usually derive from trials' secondary end points. Taking this limitation in mind, bariatric/metabolic surgery action on blood pressure is reaching a significant proportion of hypertension resolution or improvement. In this review, we discussed the current evidence on the impact of bariatric/metabolic surgery on blood pressure control and pointed out perspectives in this research area.

Abstract
Obesity and diabetes are associated with deficits in multiple neurocognitive domains and increased risk for dementia. Over the last two decades, there has been a significant increase in bariatric and metabolic surgery worldwide, driven by rising intertwined pandemics of obesity and diabetes, along with improvement in surgical techniques. Patients undergoing bariatric surgery achieve a significant decrease in their excess weight and a multitude of sequela associated with obesity, diabetes, and metabolic syndrome. Glucagon-like peptide 1 (GLP-1) is an intestinal peptide that has been implicated as one of the weight loss-independent mechanisms in how bariatric surgery affects type 2 diabetes. GLP-1 improves insulin secretion, inhibits apoptosis and induce pancreatic islet neogenesis, promotes satiety, and can regulate heart rate and blood pressure. Moreover, numerous studies have demonstrated potential neuroprotective and neurotrophic effects of GLP-1. Increased GLP-1 activity has been shown to increase cortical activity, promote neuronal growth, and inhibit neuronal degeneration. Specifically, in experimental studies on Alzheimer's disease, GLP-1 decreases amyloid deposition and neurofibrillary tangles. Furthermore, recent studies have also suggested that GLP-1 based therapies, new class of antidiabetic drugs, have favorable effects on neurodegenerative disorders such as Alzheimer's disease. We present a hypothesis that bariatric surgery can help delay or even prevent the onset of Alzheimer's disease in long-term by increasing the levels of GLP-1. This hypothesis has a potential for many studies from basic science projects to large population studies to fully understand the neurological and cognitive consequences of bariatric surgery and associated rise in GLP-1.

Abstract
BACKGROUND Excellent results have been reported with mini-gastric bypass. We adopted and modified the one-anastomosis gastric bypass (OAGB) concept. Herein is our approach, results, and long-term follow-up (FU). METHODS Initial 1200 patients submitted to laparoscopic OAGB between 2002 and 2008 were analyzed after a 6-12-year FU. Mean age was 43 years (12-74) and body mass index (BMI) 46 kg/m2 (33-86). There were 697 (58 %) without previous or simultaneous abdominal operations, 273 (23 %) with previous, 203 (17 %) with simultaneous, and 27 (2 %) performed as revisions. RESULTS Mean operating time (min) was as follows: (a) primary procedure, 86 (45-180); (b) with other operations, 112 (95-230); and (c) revisions, 180 (130-240). Intraoperative complications led to 4 (0.3 %) conversions. Complications prompted operations in 16 (1.3 %) and were solved conservatively in 12 (1 %). Long-term complications occurred in 12 (1 %). There were 2 (0.16 %) deaths. Thirty-day and late readmission rates were 0.8 and 1 %. Cumulative FU was 87 and 70 % at 6 and 12 years. The highest mean percent excess weight loss was 88 % (at 2 years), then 77 and 70 %, 6 and 12 years postoperatively. Mean BMI (kg/m2) decreased from 46 to 26.6 and was 28.5 and 29.9 at those time frames. Remission or improvement of comorbidities was achieved in most patients. The quality of life index was satisfactory in all parameters from 6 months onwards. CONCLUSIONS Laparoscopic OAGB is safe and effective. It reduces difficulty, operating time, and early and late complications of Roux-en-Y gastric bypass. Long-term weight loss, resolution of comorbidities, and degree of satisfaction are similar to results obtained with more aggressive and complex techniques. It is currently a robust and powerful alternative in bariatric surgery.

Abstract
PURPOSE Although bariatric surgery fosters heightened excess weight loss values, nutritional deficiencies are prominent; one of the most common being iron deficiency anemia. The purpose is to elucidate the frequency of anemia in Roux-en-Y gastric bypass and sleeve gastrectomy subjects. MATERIALS AND METHODS A retrospective analysis was conducted, in subjects (N = 100) diagnosed with type II diabetes who were randomized into sleeve gastrectomy or Roux-en-Y gastric bypass and intensive medical therapy. RESULTS Anemia was more common in female subjects who underwent sleeve gastrectomy-roughly half developed microcytosis at 24 months and thereafter. CONCLUSION The etiology of anemia appears to be iron-related and precipitated by the female sex. Scant iron supplementation is likely causative. However, anemia of chronic inflammation cannot be discounted as being somewhat causal. Subsequently, the aggregate may have had a synergistic influence.

Abstract
CONTEXT The mechanisms mediating the short- and long-term improvements in glucose homeostasis following bariatric/metabolic surgery remain incompletely understood. OBJECTIVE To investigate whether a reduction in adipose tissue inflammation plays a role in the metabolic improvements seen after bariatric/metabolic surgery, both in the short-term and longer-term. DESIGN Fasting blood and subcutaneous abdominal adipose tissue were obtained before (n=14), at one month (n=9), and 6-12months (n=14) after bariatric/metabolic surgery from individuals with obesity who were not on insulin or anti-diabetes medication. Adipose tissue inflammation was assessed by a combination of whole-tissue gene expression and flow cytometry-based quantification of tissue leukocytes. RESULTS One month after surgery, body weight was reduced by 13.5±4.4kg (p<0.001), with improvements in glucose tolerance reflected by a decrease in area-under-the-curve (AUC) glucose in 3-h oral glucose tolerance tests (-105±98mmol/L * min; p=0.009) and enhanced pancreatic β-cell function (insulinogenic index: +0.8±0.9pmol/mmol; p=0.032), but no change in estimated insulin sensitivity (Matsuda insulin sensitivity index [ISI]; p=0.720). Furthermore, although biomarkers of systemic inflammation and pro-inflammatory gene expression in adipose tissue remained unchanged, the number of neutrophils increased in adipose tissue 15-20 fold (p<0.001), with less substantial increases in other leukocyte populations. By the 6-12month follow-up visit, body weight was reduced by 34.8±10.8kg (p<0.001) relative to baseline, and glucose tolerance was further improved (AUC glucose -276±229; p<0.001) along with estimated insulin sensitivity (Matsuda ISI: +4.6±3.2; p<0.001). In addition, improvements in systemic inflammation were reflected by reductions in circulating C-reactive protein (CRP; -2.0±5.3mg/dL; p=0.002), and increased serum adiponectin (+1358±1406pg/mL; p=0.003). However, leukocyte infiltration of adipose tissue remained elevated relative to baseline, with pro-inflammatory cytokine mRNA expression unchanged, while adiponectin mRNA expression trended downward (p=0.069). CONCLUSION Both the short- and longer-term metabolic improvements following bariatric/metabolic surgery occur without significant reductions in measures of adipose tissue inflammation, as assessed by measuring the expression of genes encoding key mediators of inflammation and by flow cytometric immunophenotyping and quantification of adipose tissue leukocytes.

Abstract
Sleeve gastrectomy, gastric bypass, gastric banding, and duodenal switch are the most common bariatric procedures performed worldwide. Ninety-five percent of bariatric operations are performed with minimally invasive laparoscopic technique. Perioperative morbidities and mortalities average around 5% and 0.2%, respectively. Long-term weight loss averages around 15% to 25% or about 80 to 100 lbs (40-50 kg). Comorbidities, including type 2 diabetes, hypertension, dyslipidemia, sleep apnea, arthritis, gastroesophageal reflux disease, and nonalcoholic fatty liver disease, improve or resolve after bariatric surgery.

Abstract
INTRODUCTION Metabolic surgery is known to impact glucose tolerance but the exact mechanism is still unclear. Based on recently-published data, especially the role of the hindgut may require redefinition. METHODS Either a loop duodeno-jejunostomy (DJOS) with exclusion of one third of total intestinal length, a loop duodeno-ileostomy (DiOS, exclusion of two thirds), or SHAM operation was performed in 9-week-old Zucker diabetic fatty rats. One, 3, and 6 months after surgery, an oral glucose tolerance test (OGTT) and glucose-stimulated hormone analyses were conducted. Body weight was documented weekly. RESULTS DJOS and DiOS animals showed significantly better glucose control in all OGTTs than the SHAM group (two-way ANOVA p < 0.0001). Body weight developed largely parallel in both intervention groups; SHAM animals had gained significantly less weight after 6 months (Mann-Whitney DJOS/DiOS vs. SHAM p < 0.05, DJOS vs. DiOS p > 0.05). Operative interventions had no impact on GLP-1 and GIP levels at any time point (Mann-Whitney p > 0.05 for all). DJOS/DiOS operations could preserve insulin production up to 6 months, while there was already a sharp decline of insulin levels in the SHAM group (Mann-Whitney: DJOS/DiOS vs. SHAM p < 0.05 for all time points). Additionally, insulin sensitivity was improved significantly 1 month postoperative in both intervention groups compared to SHAM (Mann-Whitney DJOS/DiOS vs. SHAM p < 0.05). CONCLUSION The data of the current study demonstrate a sharp amelioration of glucose control after duodenal exclusion with unchanged levels of GLP-1 and GIP. Direct or delayed hindgut stimulation had no impact on glucose control in our model.

Abstract
No randomized clinical trials (RCTs) have yet evaluated the bariatric surgery's efficacy and safety in patients newly diagnosed with type 2 diabetes mellitus (T2DM). The aim of this multicenter RCT is to compare bariatric surgery, particularly laparoscopic sleeve gastrectomy (LSG), with conventional medical therapy (CMT) in obese patients (body mass index between 30 and 42 kg/m2) newly diagnosed with T2DM and without any diabetes-related complications at any stage. A total of 100 eligible patients will be randomized at a 1:1 ratio to undergo one of the two planned treatments and will be followed for at least 6 years after randomization. The main objective of the ESINODOP trial is to investigate the efficacy of LSG compared with CMT alone in inducing and maintaining a remission of T2DM (defined as HbA1c levels ≤6.0 %, without active pharmacologic therapy after 1 year). The remission of T2DM will also be evaluated with the criteria provided by the American Diabetes Association (ADA), and the additional parameters such as adverse event rates, micro- and macrovascular complications, weight loss, gastrointestinal hormones, and quality of life will be compared. The study started on September 2015 and the planned recruitment period is 3 years. Patient recruitment and follow-up take place in the two diabetology and nutrition centers participating in the study, which are performed on a national basis. The ESINODOP trial is designed with the intent of comparing the efficacy of CMT alone to that of CMT in conjunction with LSG performed at the time of diabetes diagnosis in mildly obese diabetic patients. Currently, patients with these characteristics are not eligible for bariatric/metabolic surgery.

Abstract
BACKGROUND Morbid obesity is a medical and economic challenge. Patients who have the indications for bariatric surgery face a long way from the first visit until surgery and a high utilization of resources is required. OBJECTIVES The present study aimed to evaluate labor costs and labor time required to supervise obese patients from their first visit until preparation of a bariatric report to ask for cost acceptance of bariatric surgery from their health insurance. In addition, the reasons for not receiving bariatric surgery after receiving cost acceptance from the health insurance were evaluated. MATERIAL AND METHODS Patients who had indications for bariatric surgery according to the S3 guidelines between 2012 and 2013, were evaluated regarding labor costs and labor time of the process from the first visit until receiving cost acceptance from their health insurance. Furthermore, body mass index (BMI), age, sex, Edmonton Obesity Staging System (EOSS) stage and comorbidities were evaluated. Patients who had not received surgery up to December 2015 were contacted via telephone to ask for the reasons. RESULTS In the present study 176 patients were evaluated (110 females, 62.5%). Until preparation of a bariatric report the patients required an average of 2.7 combined visits in the department of surgery with the department of nutrition, 1.7 visits in the department of psychosomatic medicine, 1.5 separate visits in the department of nutrition and 1.4 visits in the department of internal medicine. Average labor costs from the first visit until the bariatric survey were 404.90 ± 117.00 euros and 130 out of 176 bariatric reports were accepted by the health insurance (73.8%). For another 40 patients a second bariatric survey was made and 20 of these (50%) were accepted, which results in a total acceptance rate of 85.2% (150 out of 176). After a mean follow-up of 2.8 ± 1.1 years only 93 out of 176 patients had received bariatric surgery (53.8%). Of these 16 had received acceptance of surgery by their health insurance only after a second bariatric survey. CONCLUSION A large amount of labor and financial resources are required for treatment of obese patients from first presentation up to bariatric surgery. The cost-benefit calculation of an obesity center needs to include that approximately one half of the patients do not receive surgery within more than 2.5 years.

Abstract
Highlights Quality-of-life measures improve as early as 3 months after bariatric surgery.There is wide variability in reporting that renders direct comparisons difficult.The available comparisons between RYGB and sleeve gastrectomy could not detect any difference.Improvement in PRO measures might be related to weight loss.Larger and better designed studies are required to achieve discrimination in PRO measures. Background Obesity is associated with reduced quality-of-life (QoL), which generally improves after bariatric surgery. The differential effect of each type of surgery (gastric sleeve [SG] and gastric bypass [RYGB]) on QoL is not yet fully understood. Objectives To understand which of these surgeries offers greatest improvement in QoL and patient satisfaction. Methods Systematic literature search on Pubmed in July 2014. Relevant articles were selected in a step-wise approach. The 2482 titles were scanned for relevance and 191 were selected for abstract reviewing; and 88 papers were selected for full text analysis. Results Only 5 papers compared the 2 techniques and only 17 more had retrievable data either on SG or RYGB. The reports were very heterogeneous, preventing a direct comparison of patient reported outcomes (PRO) among studies.Improved results have been reported as early has 3 months and SF-36 scores were improved in all domains in medium to long-term. The question remains whether the improvement in QoL is related to the weight loss and which factors are associated with improved patients' perceptions. Conclusions There is wide heterogeneity in the reporting of PRO measures after bariatric surgery, but data is consistent with a significant improvement after both surgeries.Larger and better-designed studies are required to understand if there are significant differences in the quality of life after SG or RYGB.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) is a highly prevalent sleep disorder, particularly in bariatric patients. It is known to be tightly linked with metabolic abnormalities and cardiovascular morbidity. Obesity is the most noteworthy individual risk factor for OSA. The aim of this study was to investigate the effect of a laparoscopic Roux-en-Y gastric bypass (LRYGB) on OSA one year after surgery. METHODS In this prospective multicenter study standard overnight cardiorespiratory recording was conducted 12 months after bariatric surgery in 132 patients who had OSA in the baseline recording prior to the operation. The main outcome measures were changes in the prevalence of OSA and apnea-hypopnea index (AHI). In addition, the changes in anthropometric and demographic measurements including weight, body mass index (BMI), and waist and neck circumference were evaluated. A sleep symptom questionnaire was administered at baseline and at 12 months. RESULTS The prevalence of OSA decreased from 71% at baseline to 44% at 12 months after surgery (p < 0.001). OSA was cured in 45% and cured or improved in 78% of the patients, but moderate or severe OSA still persisted in 20% of the patients after the operation. De novo OSA occurred in eight percent of the patients, and total AHI decreased from 27.8 events/h to 9.9 events/h (p < 0.001). CONCLUSIONS LRYGB is effective in treating OSA. However, the findings demonstrate that a postoperative cardiorespiratory recording is needed in order to identify the patients with persistent moderate to severe OSA after the operation.

Abstract
BACKGROUND The prevalence of obesity and obesity-related morbidity in end-stage renal disease patients is rising. Although it is established that obesity does not abrogate the transplant benefit with respect to lower long-term mortality and cardiovascular risk, it is associated with increased graft failure, delayed graft function, surgical complications, prolonged hospital stay, and costs. OBJECTIVES To examine the safety and efficacy of LSG (laparoscopic sleeve gastrectomy) in renal transplant candidates and evaluate transplant outcomes. SETTING Single-center prospective nonrandomized trial METHODS: We here report on a prospective single-center trial establishing a 2-step approach for obese renal transplant candidates. Patients with end-stage renal disease and a BMI (body mass index) of 35 kg/m2 or higher underwent laparoscopic sleeve gastrectomy. After reaching a BMI of<35 kg/m2, patients were waitlisted for kidney transplantation. Age, gender, body mass index (BMI), associated co-morbidities, cause of end-stage renal disease, surgical complications, and outcome after kidney transplantation (graft survival, incidence of delayed graft function, incidence of rejection, serum creatinine) were collected. RESULTS LSG was performed in 8 renal transplant candidates with a mean BMI of 38.8 kg/m2 each. BMI dropped to below 35 kg/m2 within a median of 3 months. Percent excess body mass index loss (%EBMIL) was 62.7% at 1 year after LSG. Within 17 months (mean) after metabolic surgery, 7 patients underwent kidney transplantation. All transplants were successful with a serum creatinine of 1.9±.8 mg/dL at discharge and stable allograft function thereafter. Mean follow-up was 3.2±1.4 years; no patient was lost to follow-up. CONCLUSION LSG is safe and efficacious for treatment of obesity in renal transplant candidates. Rapid and sustained weight loss and subsequent waitlisting for kidney transplantation may reduce overall and in particular posttransplant patient morbidity.

Abstract
Obesity is a worldwide main health concern, with a high treatment failure. This chapter focuses on the definition of obesity, based on excessive fat accumulation and thus underscores the importance of body composition, and the clinical tools currently used to diagnose it, mainly body mass index that is only a proxy measure of body composition. It also highlights the importance of the personal commitment to comply to a healthy diet and physical activity recommendations since surgery is most effective when accompanied by lifestyle modifications. Additionally, it addresses the description of types of patients who could benefit most from surgical management of excessive body fat percentage and metabolic derangements, as well as on the indications for surgery that are currently valid.

Abstract
After bariatric surgery there are some favourable effects on comorbidities of obesity as glucose and lipid metabolism besides weight loss. Therefore surgical measures targeting at improvement of such metabolic disorders especially diabetes type 2 has been called "metabolic surgery". The complexity of its underlying metabolic mechanisms is not yet clear, but restriction of energy and weight loss (maintenance) seem to be the cornerstones.Risks of these procedures which are drawn of the established methods of bariatric surgery are reported to be relatively low in qualified centers. Being an elective operation special focus has to be set on mortality and morbidity, numbers of therapeutic failure and redo-surgery. Multiple irreversible and not seldom severe, potentially life-threatening consequences of bariatric surgery require consequent interdisciplinary postsurgery care and therapy throughout the whole life, especially substitution therapy of deficiencies due to post-operative malassimilation, if necessary. Little is known about long term consequences of modified anatomy and function of digestive system caused by surgery, and there may be a delay of (many) years until manifestation of clinical problems.Obese diabetics (BMI ≥ 35 kg/m2) should primarily be treated conservatively in an "individualized" way. Metabolic surgery should not be considered earlier than failure of the conservative approach has to be stated (in this case as an "ultima ratio" in well defined trials). A broader use of metabolic surgery beyond this narrow frame is not yet supported by long-term evidence-based data showing its value and safety.

Abstract
One of the aims of laparoscopic surgery is to improve upon the results obtained by open surgery. This clearly appears to have been achieved in bariatric surgery. Two-dimensional (2-D) systems have been used to date, though new 3-dimensional (3-D) technologies have been introduced in an attempt to improve surgeon vision and thus increase the safety of the surgical techniques. Sixty obese patients underwent sleeve gastrectomy using a device equipped with 3-D optics allowing surgery to be viewed by the surgeon in 3 dimensions by using a specific monitor and wearing appropriate glasses. The mean patient age was 48.1 years. The mean weight was 114 kg (range, 92-172), with a mean body mass index (BMI) of 44 ± 5.21 kg/m(2). All surgeries were performed using the 3-D system, with a mean surgical time of 71 ± 49.6 minutes and a mean hospital stay of 3.0 ± 1.2 days. Only 1 intraoperative complication was recorded: retroperitoneal bleeding on insertion of the optical trocar. Over a mean follow-up period of 12 months, the mean body weight of the patients was 88 kg (range, 71-121), with a BMI of 30.56 ± 3.98 kg/m(2) and a percentage excess weight loss of 68.14% ± 7.89%. There was clear improvement of both the blood pressure and glucose levels. Three-dimensional sleeve gastrectomy is safe, viable, and fully reproducible compared with 2-D surgery, improving visualization of the surgical field, safety, and surgeon convenience. Randomized studies involving larger patient samples are needed for the comparison of results.

Abstract
Purpose Measurement of small bowel length (SBL) is a common procedure in gastrointestinal surgery. When required, repeated SBL measurements can be done during surgery. Our aim was to evaluate whether these repeated measurements differ in SBL results. Methods Small bowel length was measured during laparotomy in 28 patients between ligament of Treitz and caecum, using a standard measure, two times in each patient consecutively by two different surgeons from the anti-mesenteric border of the bowel. Results The median age was 33 (19–67) including 18 male. There were 16 healthy donors for living related liver transplantations. Second measurements, performed immediately after the first measurements, significantly shortened the measured SBLs in the same patients (580 ± 103 vs. 485 ± 78 cm, p < 0.001). Conclusions During surgery, repeated length measurements caused contractions in the small bowel and this resulted to a significant decrease in the SBL. This should be keep in mind to prevent mismeasurements.

Abstract
A survey to evaluate the current status of bariatric and metabolic operations in Korea was conducted. Data from 5467 cases (32 hospitals) were collected. The annual numbers of bariatric and metabolic operations increased each year, from 139 in 2003 to 1686 in 2013. Adjustable gastric band (AGB, 67.2 %) was the most common operation, followed by sleeve gastrectomy (SG, 14.2 %), and Roux-en-Y gastric bypass (RYGB, 12.7 %). Mean patient age and body mass index (BMI) were 35.4 years and 35.9 kg/m2, respectively. In-hospital morbidity and mortality rates were 6 % (114/2305) and 0.25 % (5/2176), respectively. In Korea, AGB was the most common operation because of the availability and activity of specialized bariatric clinics. These national survey results established a baseline for future data collection.

Abstract
AIM To evaluate the feasibility of side-to-side anastomosis of the lesser curvature of stomach and jejunum in laparoscopic Roux-en-Y gastric bypass (LRYGB).
METHODS Seventy-seven patients received side-to-side anastomosis of the lesser curvature of stomach and jejunum by utilization of linear stapler in LRYGB from April 2012 to July 2015 were retrospectively analyzed.
RESULTS All patients were successfully completed laparoscopic gastric bypass with the side-to-side anastomosis of the lesser curvature of stomach and jejunum. No patient was switched to laparotomy during operation. No early complications including gastrointestinal anastomotic bleeding, fistula, obstruction, deep vein thrombosis, incision infections, intra-abdominal hernia complications were found. One patient complicated with stricture of gastrojejunal anastomosis (1.3%) and six patients complicated with incomplete intestinal obstruction (7.8%). BMI and HbA1c determined at 3, 6, 12, 24 mo during follow up period were significantly reduced compared with preoperative baselines respectively. The percentage of patients who maintain HbA1c (%) < 6.5% without taking antidiabetic drugs reached to 61.0%, 63.6%, 75.0%, and 63.6% respectively. The outcome parameters of concomitant diseases were significantly improved too.
CONCLUSION Present surgery is a safety and feasibility procedure. It is effective to lighten the body weight of patients and improve type 2 diabetes and related complications.

Abstract
BACKGROUND Bariatric surgery is gastrointestinal surgery for weight control, and metabolic surgery refers to the use of surgery to primarily and purposely treat type 2 diabetes mellitus (T2DM)/metabolic syndrome mellitus. METHODS The most recent literature was reviewed for surgery and T2DM in a non-systematic fashion. RESULTS Roux-Y gastric bypass, biliopancreatic diversion with duodenal switch, and sleeve gastrectomy (SG) are the dominant procedures today. SG is emerging as the most popular operation worldwide. Laparoscopy has made metabolic surgery as safe as other common abdominal procedures. A BMI > 60 kg/m2, however, exposes a significantly higher perioperative risk. Most patients experience a sustained improvement of glycemic control with subsequent reduction of cardiovascular events. The remission rates depend on the severity and duration of diabetes. Prevention of long-term nutritional deficits and monitoring of metabolism require lifelong medical surveillance of the patients. CONCLUSIONS The profound impact of weight reduction surgery on glucose metabolism explains the growing interest in treating T2DM by surgical means. Metabolic surgery is a safe option for carefully selected patients with metabolic syndrome.

Abstract
BACKGROUND Interest is growing in preventing readmissions as payers start to link reimbursement to readmission rates. The purpose of this study was to assess factors contributing to 30-day readmission for patients undergoing gastric bypass (GB) and determine whether these readmissions may be preventable. METHODS Data were from the Pennsylvania Health Care Cost Containment Council (PHC4) and included all patients undergoing elective GB for obesity in 2011 (n = 4427). The outcomes measured were length of stay (LOS) and 30-day readmission. Univariate comparisons between characteristics of readmitted (n = 298) and non-readmitted (n = 4133) patients were performed. Readmission was modeled using multivariate logistic regression; LOS was modeled using linear regression. RESULTS Of the 298 (6.6%) patients who were readmitted, the most common causes for readmission were bleeding (11.84%), infection (8.88%), and abdominal pain (7.89%). In multivariate analyses, black race, open GB, and history of myocardial infarction or rheumatoid arthritis were associated with increased odds of readmission. Longer LOS was also predictive of readmission (OR 1.10, p = <0.0001). Patients who were >50 years old and those with history of congestive heart failure, peripheral vascular, and kidney diseases were more likely to have longer LOS. Black race, open surgery, and discharge to an extended care facility were also predictive of prolonged LOS. CONCLUSIONS The most common causes of readmission following elective GB were bleeding, infection, and abdominal pain. Since several patient-specific factors were associated with higher odds of readmission and longer LOS, there are opportunities to design interventions to prevent readmissions and decrease LOS in this patient population.

Abstract
BACKGROUND Type 1 diabetes mellitus (T1DM) has a rising global prevalence. Although it is vastly outnumbered by type 2 diabetes mellitus rates, it remains a persistent worldwide source of morbidity and mortality. Increasingly, its sufferers are afflicted by obesity and its complications. The objective of the study is to quantify the effects of bariatric surgery on T1DM by appraising the primary outcomes of glycosylated haemoglobin (HbA1c), insulin requirements and body mass index (BMI). Secondary outcomes included blood pressure, triglycerides and cholesterol biochemistry. METHODS A systematic review of studies reporting pre-operative and post-operative outcomes in T1DM patients undergoing bariatric surgery was done. Data were meta-analysed using random effects modelling. Subgroup analysis and quality scoring were assessed. RESULTS Bariatric surgery in obese T1DM patients is associated with a significant reduction in insulin requirement (-48.95 units, 95 % CI of -56.27, -41.62), insulin requirement per kilogramme (-0.391, 95 % CI of -0.51, -0.27), HbA1c (-0.933, 95 % CI of -1.604, -0.262) and BMI (-11.04 kg/m(2), 95 % CI of -13.49, -8.59). Surgery is also associated with a statistically significant reduction in systolic and diastolic blood pressure and a significant beneficial rise in HDL. Heterogeneity in these results was high, and study quality was low overall. CONCLUSIONS Bariatric surgery in obese T1DM patients is associated with a significant improvement in insulin requirement and a significant though modest effect on HbA1c. These early results require further substantiation with future studies focusing on higher levels of evidence. This may offer a deeper understanding of diabetogenesis and can contribute to better selection and stratification of diabetic patients for metabolic surgery and future metabolic treatment strategies.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is becoming a leading cause of global liver disease that is associated with the rising prevalence of obesity worldwide. There is now increasing clinical and mechanistic evidence reporting on the metabolic and weight loss effects of bariatric surgery on improving NAFLD in obese patients. OBJECTIVES The aim of this paper was to quantify the effects of bariatric surgery on NAFLD by appraising the modulation between pre- and post-operative liver enzyme levels (as markers of liver injury) and liver histology. METHODS A systematic review of studies reporting pre-operative and post-operative liver enzymes or liver histology was done in obese patients with NAFLD undergoing bariatric surgery. Data were meta-analysed using random-effects modelling. Subgroup analysis, quality scoring and risk of bias were assessed. RESULTS Bariatric surgery is associated with a significant reduction in the weighted incidence of a number of histological features of NAFLD including steatosis (50.2 and 95 %CI of 35.5-65.0), fibrosis (11.9 and 95 %CI of 7.4-16.3 %), hepatocyte ballooning (67.7 and 95 %CI 56.9-78.5) and lobular inflammation (50.7 and 95 %CI 26.6-74.8 %). Surgery is also associated with a reduction in liver enzyme levels, with statistically significant reductions in ALT (11.36 u/l, 95 %CI 8.36-14.39), AST (3.91 u/l, 95 %CI 2.23-5.59), ALP (10.55 u/l, 95 %CI 4.40-16.70) and gamma-GT (18.39 u/l, 95 %CI 12.62-24.16). Heterogeneity in results was high. CONCLUSIONS Bariatric surgery is associated with a significant improvement in both histological and biochemical markers of NAFLD. Future studies must focus on higher levels of evidence to better identify the benefits of bariatric surgery on liver disease in order to enhance future treatment strategies in the management of NAFLD.

Abstract
Obesity and its associated medical conditions continue to increase and add significant burden to patients, as well as health-care systems, worldwide. Bariatric surgery is the most effective treatment for severe obesity and its comorbidities, and resolution of diabetes is weight loss-independent in the case of some operations. Although these weight-independent effects are frequently described clinically, the mechanisms behind them are not well understood and remain an intense area of focus in the growing field of metabolic and bariatric surgery. Perceptions of the mechanisms responsible for the beneficial metabolic effects of metabolic/bariatric operations have shifted from being mostly restrictive and malabsorption over the last 10 to 15 years to being more neuro-hormonal in origin. In this review, we describe recent basic and clinical findings of the major clinical procedures (adjustable gastric banding, vertical sleeve gastrectomy, Roux-en-Y gastric bypass, and biliopancreatic diversion) as well as other experimental procedures (ileal interposition and bile diversion) that recapitulate many of the metabolic effects of these complex operations in a simpler fashion. As the role of bile acids and the gut microbiome on metabolism is becoming increasingly well described, their potential roles in these improvements following metabolic surgery are becoming better appreciated. Bile acid and gut microbiome changes, in light of recent developments, are discussed in the context of these surgical procedures, as well as their implications for future study.
