[PMID: 38436919 PMCID: PMC11031453 DOI: 10.1007/s11695-023-06979-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 11/28/2023] [Accepted: 12/06/2023] [Indexed: 03/05/2024]
Abstract
PURPOSE Obesity and its related severe comorbidities are increasing rapidly. The duodenal-jejunal bypass is an endoscopically implanted device (mimicking the Roux-en-Y gastric bypass) developed to support weight reduction and improve type 2 diabetes control. MATERIALS AND METHODS Retrospective data analysis of consecutive patients undergoing duodenal-jejunal bypass (EndoBarrier®, DJB) implantation between 2013 and 2017 was performed to evaluate safety as well as short- and long-term efficacy. RESULTS One hundred and twenty-one patients (mean BMI of 43.1 ± 7.2 kg/m2 and weight of 138.2 ± 28.6 kg) underwent DJB implantation. The mean dwelling time was 15.5 months, the mean total body weight loss (%TBWL) after explantation was 10.3% ± 7.9% (14.2 kg, p < 0.0001), and the mean BMI was 39.5 ± 7.3 kg/m2 (p < 0.0001). There was no significant weight gain 24 months after the explantation. Seventy-seven patients had type 2 diabetes mellitus (T2DM) with a mean HbA1c before implantation of 5.6% (n = 52). The mean HbA1c after explantation was 5.1% (p = 0.0001). Significant reductions in transaminase and lipid levels before and after explantation were observed. One complication occurred during implantation and another during explantation. In 16 patients, the device had to be extracted earlier than expected (7 for severe adverse events and 9 for adverse events; 13.2%). CONCLUSION Despite an evident rate of adverse events, the DJB shows promise as a weight-loss procedure. Our results show that some patients implanted with the device maintained reduced weight even 24 months after explantation, while many improved T2DM control.

Abstract
Previous data from short term studies have shown an efficacy of the duodenal-jejunal bypass liner (DJBL) for weight loss. However, less data is available regarding weight change after device removal and possible predictors for weight loss. This is a retrospective chart review of all patients who had DJBL inserted at the University Hospital Zurich between December 2012 and June 2015. A total of 27 patients had DJBL insertion. The median BMI at baseline was 38.5 (34.0-42.2) kg/m2 . In the 24 patients with DJBL treatment >3 months (failed implantation or early removal due to side effects in 3 patients), the mean duration of implantation was 42.9 ± 13.1 weeks. During the treatment, the mean total body weight loss (%TBWL) was 15.0 ± 8.3%. Fifteen patients had long-term follow-up data available (mean duration of follow-up 4.0 ± 0.9 years). The mean weight change was 12.7 ± 12.8 kg, corresponding with a mean % weight regain of 13.3 ± 13.3%. Five patients (33.3%) subsequently underwent bariatric surgery. In patients with class I obesity (BMI <35 kg/m2 at baseline), 4 out of 6 (66.7%) had a stable weight or only a weight regain <7%. In contrast, no patient with BMI >35 kg/m2 at baseline was able to keep weight regain below 7%. DJBL is an effective treatment for obesity, but substantial weight regain occurs during long-term follow up after the device removal, in particular in patients with BMI > 35 kg/m2 .

Abstract
Nonalcoholic fatty liver disease (NAFLD), including advanced-stage nonalcoholic steatohepatitis (NASH), is currently the most common chronic liver disease worldwide and is projected to become the leading indication for liver transplantation (LT). However, there are no effective pharmacological therapies for NAFLD. Endoscopic bariatric and metabolic therapies (EBMTs) are less invasive procedures for the treatment of obesity and its metabolic comorbidities. Several recent studies have demonstrated the beneficial effects of EBMTs on NAFLD/NASH. In this review, we summarize the major EBMTs and their mechanisms of action. We further discuss the current evidence on the efficacy and safety of EBMTs in people with NAFLD/NASH and obese cirrhotic LT candidates. The potential utility of EBMTs in reducing liver volume and perioperative complications in bariatric surgery candidates is also discussed. Moreover, we review the development of liver abscesses as a common serious adverse event in duodenal-jejunal bypass liner implantation.

Endoscopic Bariatric Treatment with Duodenal-Jejunal Bypass Liner Improves Non-invasive Markers of Non-alcoholic Steatohepatitis. Obes Surg 2022; 32:2495-2503.

Abstract
Purpose People with obesity often develop non-alcoholic fatty liver disease (NAFLD) and are at high risk of progression to non-alcoholic steatohepatitis (NASH). Few therapies are effective other than bariatric surgery. We therefore analyzed data from duodenal-jejunal bypass liner (DJBL) patients regarding steatosis, fibrosis, and NASH. Methods Consecutive DJBL patients with type 2 diabetes underwent standardized assessments up to device removal at 48 weeks. These included aspartate and alanine transaminase (AST, ALT), controlled attenuation parameter (CAP, for steatosis), and liver stiffness measurement (LSM, for fibrosis). The NAFLD fibrosis score (NFS), fibrosis-4 score (FIB4), and enhanced liver fibrosis (ELF) test were also used to assess fibrosis and the Fibroscan-AST (FAST) score to assess NASH. Mixed models were used and missing data were accounted for with multiple imputation. Results Thirty-two patients (18 female, mean age 55.1, mean BMI 40.2 kg/m2) were included. After 48 weeks, the change compared to baseline with 95% CI was a factor 0.74 (0.65 to 0.84) for AST, 0.63 (0.53 to 0.75) for ALT, and a difference of − 0.21 (− 0.28 to − 0.13) for FAST, all with p < 0.001. Fibrosis based on LSM, NFS, and ELF did not change whereas FIB4 exhibited slight improvement. Eight DJBL were explanted early due to device-related complications and eight complications led to hospitalization. Conclusions One year of DJBL therapy is associated with relevant improvements in non-invasive markers of steatosis and NASH, but not fibrosis, and is accompanied by a substantial number of complications. Given the lack of alternatives, DJBL deserves further attention. Graphical abstract ![]()

Abstract
Nowadays, nonalcoholic fatty liver disease is a common metabolic liver disease of all ages worldwide. However, current pharmacological and surgical treatments are accompanied with side effects and complications. EndoBarrier, a less invasive bariatric surgery, blocks the upper portion of the intestine to reduce nutrition absorption. To mimic the nutrient restriction effect of EndoBarrier, thiol-containing materials may bind to the thiol groups of the mucus with an enhanced mucoadhesive property. Here, we develop thiolated alginate with cysteine conjugation via an N-(3-dimethylaminopropyl)-N-ethylcarbodiimide/N-hydroxysuccinimide reaction. The alginate–cysteine (AC) exhibits excellent mucoadhesive properties and forms a physical barrier in the intestine to reduce absorption significantly, which was tested with both in vitro and in vivo mucoadhesive test and barrier function test. The nontoxicity property of AC was also proven with WST-1 and live and dead stain. In addition, AC demonstrates potent carrier properties of extending the release of resveratrol to improve the efficacy with the test of the transwell system in the release profile. In the long-term therapeutic evaluation, alginate cysteine with resveratrol (ACR) is orally administrated daily to mice with an methionine choline-deficient diet. The results of this in vivo study show that developed ACR could effectively alleviate fat degeneration in the liver and improve fat-related metabolic parameters in serum without hepatocellular damage and kidney dysfunction. In sum, AC was found to be mucoadhesive, reduce glucose absorption, alleviate inflammation, and decrease fatty degradation. This promising material exhibits the potential to be a supplement for nonalcoholic fatty liver disease.

Abstract
OBJECTIVE The aim of this study was to examine the clinical efficacy and safety of the duodenal-jejunal bypass liner (DJBL) while in situ for 12 months and for 12 months after explantation. SUMMARY BACKGROUND DATA This is the largest randomized controlled trial (RCT) of the DJBL, a medical device used for the treatment of people with type 2 diabetes mellitus (T2DM) and obesity. Endoscopic interventions have been developed as potential alternatives to those not eligible or fearful of the risks of metabolic surgery. METHODS In this multicenter open-label RCT, 170 adults with inadequately controlled T2DM and obesity were randomized to intensive medical care with or without the DJBL. Primary outcome was the percentage of participants achieving a glycated hemoglobin reduction of ≥20% at 12 months. Secondary outcomes included weight loss and cardiometabolic risk factors at 12 and 24 months. RESULTS There were no significant differences in the percentage of patients achieving the primary outcome between both groups at 12 months [DJBL 54.6% (n = 30) vs control 55.2% (n = 32); odds ratio (OR) 0.93, 95% confidence interval (CI): 0.44-2.0; P = 0.85]. Twenty-four percent (n = 16) patients achieved ≥15% weight loss in the DJBL group compared to 4% (n = 2) in the controls at 12 months (OR 8.3, 95% CI: 1.8-39; P = .007). The DJBL group experienced superior reductions in systolic blood pressure, serum cholesterol, and alanine transaminase at 12 months. There were more adverse events in the DJBL group. CONCLUSIONS The addition of the DJBL to intensive medical care was associated with superior weight loss, improvements in cardiometabolic risk factors, and fatty liver disease markers, but not glycemia, only while the device was in situ. The benefits of the devices need to be balanced against the higher rate of adverse events when making clinical decisions.

Abstract
BACKGROUND AND OBJECTIVE Endoscopic bariatric and metabolic therapies (EBMTs) are emerging minimally invasive therapeutic options for obesity and its related complications, including non-alcoholic fatty liver disease (NAFLD). This study aimed to evaluate the effects of EBMTs on NALFD in patients with obesity. METHODS Four databases were searched until Nov 2021. Randomized controlled trials (RCTs) and observational studies reporting liver-related outcomes following Food and Drug Administration (FDA)-approved and non-FDA-approved EBMTs were included. Liver parameters, metabolic parameters, and weight loss were evaluated. Risk of bias was assessed using the "risk of bias" tool in the Cochrane Collaboration for RCTs and the Methodological Index for Non-Randomized Studies criteria for observational studies. RESULTS Thirty-three studies with 1710 individuals were included. Regarding the effects of EBMTs on liver fibrosis, a significant decline of NAFLD Fibrosis Score, but not transient elastography-detected liver stiffness or Fibrosis-4 Index, was observed. EBMTs significantly improved liver steatosis (control attenuation parameter and Hepatic Steatosis Index), NAFLD Activity Score, and Homeostasis Model Assessment of Insulin Resistance. EBMTs reduced serum levels of alanine transaminase, aspartate aminotransferase, and gamma-glutamyl transpeptidase considerably. Moreover, EBMTs had reducing effects on the serum levels of triglycerides and total cholesterol as well as body weight. CONCLUSIONS Our meta-analysis suggested that EBMTs could ameliorate NAFLD based on the evidence of improved liver steatosis, liver function, and insulin resistance. Large-scale, prospective, long-term studies are warranted to clarify the role of EBMTs in patients with different stages of NAFLD.

Abstract
Obesity is characterized as abnormal or excessive fat accumulation harmful to one's health, linked to hormonal imbalances, cardiovascular illness, and coronary artery disease. Since the disease stems mainly from overconsumption, studies have aimed to control intestinal absorption as a route for treatment. In this study, chitosan-thioglycolic acid (CT) was developed as a physical barrier in the gastrointestinal tracts to inhibit nutrient uptake. CT exhibits a superior mucoadhesive property compared to chitosan both in vitro and in vivo for the ability to form disulfide bonds with the intestinal mucosa. For CT as a potential drug delivery platform, hesperidin, a herb for bodyweight control in traditional Chinese medication, is encapsulated in CT and can be released consistently from this absorption barrier. In animal studies, CT encapsulated with hesperidin (CTH) not only results in a weight-controlling effect but limits adipose accumulation by hindering absorption, suggesting a potential role in obesity treatment. Neither CT nor CTH exhibit cytotoxicity or produce adverse immunological reactions in vivo.

Several serious diseases that decrease patient quality of life and increase mortality (high blood pressure, dyslipidaemia, type 2 diabetes etc.) are associated with obesity. Obesity treatment is a multidisciplinary and complex process that requires maximum patient compliance. Change of lifestyle is fundamental in the treatment of obesity. While pharmacotherapeutic options are available, their efficacy is limited. Surgical treatment though highly effective, carries the risk of complications and is thus indicated mostly in advanced stages of obesity. Endoscopic treatments of obesity are less invasive than surgical options, and are associated with fewer complications and nutritional deficits. Currently, there is a large spectrum of endoscopic methods based on the principles of gastric volume reduction, size restriction and gastric or small bowel bypass being explored with only few available in routine practice. The aim of this publication is to present an up-to-date summary of available endoscopic methods for the treatment of obesity focusing on their efficacy, safety and nutritional aspects.

Langenbecks Arch Surg 2021; 406:1363-1377. [PMID: 33712874 PMCID: PMC8370966 DOI: 10.1007/s00423-021-02131-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Accepted: 02/09/2021] [Indexed: 12/13/2022]
Abstract
PURPOSE Based on recent scientific evidence, bariatric surgery is more effective in the management of morbid obesity and related comorbidities than conservative therapy. Pylorus preserving surgical procedures (PPBS) such as laparoscopic single-anastomosis duodeno-jejunal or duodeno-ileal bypass with sleeve gastrectomy are modified duodenal switch (DS) surgical techniques. The duodeno-jejunal bypass liner (DJBL) is a novel surgical method in the inventory of metabolism focused manual interventions that excludes duodeno-jejunal mucosa from digestion, mimicking DS procedures without the risk of surgical intervention. The aim of this article is to summarize and compare differences between safety-related features and weight loss outcomes of DJBL and PPBS. METHODS A literature search was conducted in the PubMed database. Records of DJBL-related adverse events (AEs), occurrence of PPBS-related complications and reintervention rates were collected. Mean weight, mean body mass index (BMI), percent of excess of weight loss (EWL%), percent of total weight loss (TWL%) and BMI value alterations were recorded for weight loss outcomes. RESULTS A total of 11 publications on DJBL and 6 publications on PPBS were included, involving 800 and 1462 patients, respectively. The baseline characteristics of the patients were matched. Comparison of DJBL-related AEs and PPBS-related severe complications showed an almost equal risk (risk difference (RD): -0.03 and confidence interval (CI): -0.27 to 0.21), despite higher rates among patients having received endoscopic treatment. Overall AE and complication rates classified by Clavien-Dindo showed that PPBS was superior to DJBL due to an excess risk level of 25% (RD: 0.25, CI: 0.01-0.49). Reintervention rates were more favourable in the PPBS group, without significant differences in risk (RD: -0.03, CI: -0.27 to 0.20). However, PPBS seemed more efficient regarding weight loss outcomes at 1-year follow-up according to raw data, while meta-analysis did not reveal any significant difference (odds ratio (OR): 1.08, CI: 0.74-1.59 for BMI changes). CONCLUSION Only limited conclusions can be made based on our findings. PPBS was superior to DJBL with regard to safety outcomes (GRADE IIB), which failed to support the authors' hypothesis. Surgical procedures showed lower complication rates than the incidence of DJBL-related AEs, although it should be emphasized that the low number of PPBS-related mild to moderate complications reported could be the result of incomplete data recording from the analysed publications. Weight loss outcomes favoured bariatric surgery (GRADE IIB). As the DJBL is implanted into the upper gastrointestinal tract for 6 to 12 months, it seems a promising additional method in the inventory of metabolic interventions.

Abstract
BACKGROUND & AIMS Duodenal-jejunal bypass liners (DJBLs) prevent absorption in the proximal small intestine, the site of fatty acid absorption. We sought to investigate the effects of a DJBL on blood concentrations of essential fatty acids (EFAs) and bioactive polyunsaturated fatty acids (PUFAs). METHODS Sub-study of a multicentre, randomised, controlled trial with two treatment groups. Patients aged 18-65 years with type-2 diabetes mellitus and body mass index 30-50 kg/m2 were randomised to receive a DJBL for 12 months or best medical therapy, diet and exercise. Whole plasma PUFA concentrations were determined at baseline, 10 days, 6 and 11.5 months; data were available for n = 70 patients per group. RESULTS Weight loss was significantly greater in the DJBL group compared to controls after 11.5 months: total body weight loss 11.3 ± 5.3% versus 6.0 ± 5.7% (mean difference [95% CI] = 5.27% [3.75, 6.80], p < 0.001). Absolute concentrations of both EFAs, linoleic acid and α-linolenic acid, and their bioactive derivatives, arachidonic acid, eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, were significantly lower in the DJBL group than in the control group at 6 and 11.5 months follow-up. Total serum cholesterol, LDL-cholesterol and HDL-cholesterol were also significantly lower in the DJBL group. CONCLUSION One year of DJBL therapy is associated with superior weight loss and greater reductions in total serum cholesterol and LDL-cholesterol, but also depletion of EFAs and their longer chain derivatives. DJBL therapy may need to be offset by maintaining an adequate dietary intake of PUFAs or by supplementation. TRIAL REGISTRATION ClinicalTrials.gov Identifier NCT02459561.

Abstract
The rise of endoscopic techniques allowing weight loss offers an attractive alternative to surgical interventions in Western countries where the obesity epidemic has risen dramatically. Endoscopists are well positioned to manage obesity given their broad-based medical knowledge, understanding of gastrointestinal physiology, and training in endoscopic technique. The field of bariatric and metabolic endoscopy has permitted the development of several efficacious and safe technologies. This review focuses on techniques and devices used for endoscopic management of obesity, as well as the fundamental justifications to offer those therapies to obese patients.

Abstract
Introduction: The wide net of physiological issues involved in metabolic surgery is
extremely complex. Nonetheless, compared anatomy and phisiology can provide
good clues of how digestive tracts are shaped for more or less caloric food,
for more or less fiber, for abundance and for scarcity.
Objective: To review data from Compared Anatomy and Physiology, and in the Evolutionary
Sciences that could help in the better comprehension of the metabolic
surgery.
Method: A focused review of the literature selecting information from these three
fields of knowledge in databases: Cochrane Library, Medline and SciELO,
articles and book chapters in English and Portuguese, between 1955 and 2019,
using the headings “GIP, GLP-1, PYY, type 2 diabetes, vertebrates digestive
system, hominid evolution, obesity, bariatric surgery “.
Results: The digestive tract of superior animals shows highly specialized organs to
digest and absorb specific diets. In spite of the wide variations of
digestive systems, some general rules are observed. The proximal part of the
digestive tract, facing the scarcity of sugars, is basically dedicated to
generate sugar from different substrates (gluconeogenesis). Basic proximal
gut tasks are to proportionally input free sugars, insulin, other fuels and
to generate anabolic elements to the blood, some of them obesogenic. To
limit the ingestion by satiety, by gastric emptying diminution and to limit
the excessive elevation of major fuels (sugar and fat) in the blood are
mostly the metabolict asks of the distal gut. A rapid and profound change in
human diet composition added large amounts of high glycemic index foods.
They seem to have caused an enhancement in the endocrine and metabolic
activities of the proximal gut and a reduction in these activities of the
distal gut. The most efficient models of metabolic surgery indeed make
adjustments in this proximal/distal balance in the gut metabolic activities.
Conclusion: Metabolic surgery works basically by making adjustments to the proximal and
distal gut metabolic activities that resemble the action of natural
selection in the development the digestive systems of superior animals.

Abstract
The alarming rise in obesity and relative lack of pharmacotherapies to treat, what is becoming a global epidemic, has necessitated that an increasing number of bariatric procedures be performed. Several surgical techniques have been developed during the last 50 years and the advent of laparoscopic surgery has increased the safety and efficacy of these procedures. Bariatric surgery is by a substantial margin, the most efficacious means of achieving sustained weight loss maintenance in patients with obesity. Roux-en-Y gastric bypass surgery (RYGB) elicits the most favourable metabolic outcomes with attendant benefits for type 2 diabetes and, cardiovascular disease as well as endocrine disorders and cancers in females. RYGB is the most extensively studied bariatric procedure regarding mechanism of action. In this review we catalogue the multiple alterations in secretion of gut hormones (ghrelin, obestatin, cholecystokinin, GLP-1, PYY, GIP, oxyntomodulin, glicentin and GLP-2) occurring after RYGB and summarise evidence indicating that these changes play a role in the reduction of food intake and improvements in glucose homeostasis.

Abstract
BACKGROUND Treatment with a duodenal-jejunal bypass sleeve (DJBS) induces clinically significant weight loss, but little is known about the mechanisms of action of this device. AIM The aim of this study was to characterize the mechanisms of action of the DJBS and determine the durability of weight loss and metabolic improvements. MATERIALS AND METHODS We studied a cohort of 19 subjects with severe obesity and type 2 diabetes (baseline body mass index: 43.7±5.3 kg/m). Anthropometry, body composition, blood pressure, biochemical measures, and dietary intake were monitored for 48 weeks after DJBS implantation, and then for 1 year after device removal. Gastric emptying and triglyceride absorption were measured at baseline, 8 weeks after implant, and within 3 weeks of device explant. Visceral sensory function was assessed at baseline, 4 weeks after implant, and within 3 weeks after explant. RESULTS Significant weight loss (P<0.01) occurred following DJBS placement, with a mean weight reduction of 17.0±6.5% at 48 weeks. The symptom burden following a standardized nutrient challenge was increased after DJBS implantation (P<0.05), returning to baseline after DJBS removal. Neither gastric emptying nor triglyceride absorption changed with the device in situ. A significant reduction in energy intake was observed [baseline: 7703±2978 kJ (1841±712 kcal), 24 weeks: 4824±2259 kJ (1153±540 kcal), and 48 weeks: 4474±1468 kJ (1069±351 kcal)]. After 1 year, anthropometry remained significantly improved, but there was no durable impact on metabolic outcomes. CONCLUSIONS DJBS treatment resulted in substantial weight loss. Weight loss is related to reduced caloric intake, which seems linked to an augmented upper gastrointestinal symptom response, but not altered fat absorption.

Abstract
Background Obesity surgery mortality risk scoring system (OS-MRS) classifies patients into high, intermediate and low risk, based on age, body mass index, sex and other comorbidities such as hypertension and history of pulmonary embolism. High-risk patients not only have a higher mortality but are more likely to develop post-operative complications necessitating intervention or prolonged hospital stay following bariatric surgery. Endoscopically placed duodenal-jejunal bypass sleeve (Endobarrier) has been designed to achieve weight loss and improve glycaemic control in morbidly obese patients with clinically proven effectiveness. The aim of this study was to assess if pre-operative insertion of endobarrier in high-risk patients can decrease morbidity and length of stay after bariatric surgery. Materials and Methods Between 2012 and 2014, a cohort of 11 high-risk patients had an Endobarrier inserted (E&BS group) for 1 year prior to definitive bariatric surgery. These patients were compared against a similar group undergoing primary bariatric surgery (PBS group) during same duration. The two groups were matched for age, gender, body mass index, comorbidities, surgical procedure and OS-MRS using propensity score matching. Outcome measures included operative time, morbidity, length of stay, intensive therapy unit (ITU) stay, readmission rate, percentage excess weight loss (%EWL) and percentage total weight loss (%TWL). Results Patient characteristics and OS-MRS were similar in both groups (match tolerance 0.1). There was no significant difference in total length of stay, readmission rate, %EWL and %TWL. Operative time, ITU stay, post-operative complications and severity of complications were significantly less in the E&BS group (p < 0.05) with significant likelihood of planned ITU admissions in the PBS group (p < 0.05). Conclusion Endobarrier could be considered as a pre bariatric surgical intervention in high-risk patients. It may result in improved post-operative outcomes in high-risk bariatric patients.

Abstract
PURPOSE OF REVIEW The endoscopic armamentarium against obesity and metabolic syndrome is rapidly growing and improving. Novel devices have been tested and recent data either support or reject their use. We aim to discuss current data on new endoscopic procedures addressing overweight, diabetes, and metabolic syndrome. RECENT FINDINGS Four-year follow-up of the aspiration therapy have shown efficacy and safety at long term. A recent consensus on intragastric balloon gathered experience from more than 40 000 procedures and standardized most steps of the treatment. The TransPyloric Shuttle has been proven effective at short term but carries high rates of adverse events. The endoscopic sleeve gastroplasty promotes similar weight loss to laparoscopic sleeve gastrectomy in mildly obese patien. The endoluminal magnetic partial jejunal diversion promoted good weight loss and a significant reduction in glycated hemoglobin (HbA1c) but most cases required laparoscopic assistance to couple the magnets. One-year follow-up demonstrated that the duodenal mucosal resurfacing carried a 1.0% reduction in HbA1c. SUMMARY Innovative endoscopic procedures focused on the treatment of overweight and related diseases are available and there is growing evidence supporting their use. Nonetheless, a multidisciplinary approach is mandatory. VIDEO ABSTRACT: http://links.lww.com/COG/A25.

Abstract
The duodenal-jejunal bypass liner and the intragastric balloon are endoscopically deployed devices used in the treatment of obesity and diabetes. These devices use differing mechanisms of action, and concurrent use may lead to improved efficacy. Three obese patients who suffered from weight loss plateau with the liner had the intragastric balloon inserted concurrently. All 3 patients reported subsequent significant weight loss. None of the patients reported any symptom that indicate the interference between the devices. This is the first case series in humans of successfully combining 2 independent endoscopic bariatric therapies to overcome weight loss plateau in the primary treatment of obesity.

Abstract
The worldwide rise in the prevalence of obesity supports the need for an increased interaction between ongoing clinical research in the allied fields of gastrointestinal medicine/surgery and diabetes mellitus. There have been a number of clinically-relevant advances in diabetes, obesity, and metabolic syndrome emanating from gastroenterological research. Gastric emptying is a significant factor in the development of upper gastrointestinal symptoms. However, it is not the only mechanism whereby such symptoms occur in patients with diabetes. Disorders of intrinsic pacing are involved in the control of stomach motility in patients with gastroparesis; on the other hand, there is limited impact of glycemic control on gastric emptying in patients with established diabetic gastroparesis. Upper gastrointestinal functions related to emptying and satiations are significantly associated with weight gain in obesity. Medications used in the treatment of diabetes or metabolic syndrome, particularly those related to pancreatic hormones and incretins affect upper gastrointestinal tract function and reduce hyperglycemia and facilitate weight loss. The degree of gastric emptying delay is significantly correlated with the weight loss in response to liraglutide, a glucagon-like peptide-1 analog. Network meta-analysis shows that liraglutide is one of the two most efficacious medical treatments of obesity, the other being the combination treatment phentermine-topiramate. Interventional therapies for the joint management of obesity and diabetes mellitus include newer endoscopic procedures, which require long-term follow-up and bariatric surgical procedure for which long-term follow up shows advantages for individuals with diabetes. Newer bariatric procedures are presently undergoing clinical evaluation. On the horizon, combination therapies, in part directed at gastrointestinal functions, appear promising for these indications. Ongoing and future gastroenterological research when translated to care of individuals with diabetes mellitus should provide additional options to improve their clinical outcomes.

Abstract
Endoscopic bariatric therapies that emulate some of the principles of bariatric surgery have been developed as a less invasive option for the treatment of obesity and related comorbidities. Small bowel endoscopic bariatric therapies include bypass sleeves, incisionless anastomosis systems, and duodenal mucosal resurfacing. Clinical experience with small bowel devices suggests that endoscopic bariatric procedures can be safely implemented and that these devices are effective for both weight loss and metabolic improvement. Although the mechanisms behind these effects should be further elucidated, endoscopic bariatric therapies may be more effective and safer adjunctive interventions than lifestyle modifications and pharmacological regimens for patients with obesity or obesity-related comorbidities.

Abstract
The rapid rise of obesity and type 2 diabetes poses a global threat to healthcare and is a major cause of mortality and morbidity. Bariatric surgery has revolutionised the treatment of both these conditions but is invasive and associated with an increased risk of complications. The EndoBarrier is a device placed endoscopically in the duodenum, which is designed to mimic the effects of gastric bypass surgery with the aim of inducing weight loss and improving glycaemic control. This review outlines the current clinical evidence of the device, its efficacy, potential mechanisms of action, and utility in clinical practice.

Abstract
BACKGROUND AND AIMS The early improvement in metabolic profile after sleeve gastrectomy (SG) indicates that the significant benefits of metabolic surgery are gastric in origin. We have previously demonstrated that devitalization of the gastric mucosa (without a reduction in gastric volume) in metabolically disturbed obese rats results in an improvement of obesity and its associated comorbidities. The aims of this study were to assess the technical feasibility, efficacy, and safety of gastric mucosal devitalization (GMD) in a large animal (porcine) model. METHODS A 3-arm (GMD versus SG versus sham [SH]) prospective randomized controlled trial with an 8-week follow-up period was performed. The primary endpoint was relative weight loss. Secondary endpoints were absolute body weight, abdominal visceral adiposity, abdominal subcutaneous adiposity, organ lipid content, and serum ghrelin level. RESULTS GMD resulted in a significant relative weight loss of 36% over SH at 8 weeks (P < .05). There was no significant difference in relative weight loss between GMD and SG at 4 weeks; however, SG resulted in a 29% superior relative weight loss at 8 weeks (P < .05). With regard to visceral adiposity, there was a significant benefit of GMD over SH at 8 weeks. Despite differences in relative weight loss, there was no significant difference in visceral adiposity between SG and GMD at 8 weeks. Significant improvements in GMD over SH were noted with regard to skeletal and heart muscle lipid content. GMD pigs at 8 weeks demonstrated regeneration of the gastric mucosa without ulceration or significant scarring. Despite mucosal regeneration, the abundance of serum ghrelin was significantly lower in the GMD cohort compared with the SG and SH cohorts. CONCLUSIONS GMD was technically feasible and resulted in relative weight loss and an improvement in visceral adiposity. The benefits noted were out of proportion to what would be expected with weight loss alone.
