Lymphovenous Anastomosis for Morbidly Obese Patients with Lymphedema. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2020; 8:e2860. [PMID: 33133910 PMCID: PMC7572113 DOI: 10.1097/gox.0000000000002860] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2019] [Accepted: 03/25/2020] [Indexed: 11/27/2022]
Abstract
Although patients with obesity-induced lymphedema can be treated by weight loss therapy, they find it difficult to lose the required amount of weight. The aims of this study were to clarify the characteristics of the lymphatic vessels in patients with obesity-induced lymphedema and to determine the feasibility and efficacy of lymphovenous anastomosis (LVA) in these patients. Methods Twenty-two patients (44 edematous lower limbs) with a body mass index (BMI) >35 kg/m2 (obese group) and 91 patients with lymphedema (141 edematous lower limbs) and BMI <25 kg/m2 were enrolled as a control group (nonobese group) and underwent LVA. The diameter and depth of lymphatics and the effect of LVA were compared. Results Lymphatics were detectable within 10-mm depth in the nonobese group and the obese group (3.0 ± 1.4 mm versus 3.5 ± 2.1 mm; P < 0.01). The lymphatic diameter was significantly greater in the obese group than in the nonobese group (0.79 ± 0.30 mm versus 0.54 ± 0.22 mm; P < 0.01). There was no significant difference in the rate of improvement in lymphedema after LVA between the nonobese group (9.1% ± 9.2%) and the obese group (8.9% ± 7.3%; P = 0.84). There was no correlation between the improvement rate of lymphedema and that of BMI in the obese group (P = 0.57). Conclusions LVA is a feasible procedure even in morbidly obese patients. Considering that substantial weight loss is a difficult and time-consuming task for patients, LVA combined with not gaining weight is a good option for these patients.

Factors influencing the choice between laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass. Surg Endosc 2020; 35:4691-4699. [PMID: 32909206 DOI: 10.1007/s00464-020-07933-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Accepted: 08/25/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND While laparoscopic sleeve gastrectomy (LSG) continues to be the most commonly performed bariatric operation, several variables influence surgeons' practice patterns and patients' decision-making in the type of bariatric procedure to perform. The aim of this study was to evaluate patient factors that influence the decision between laparoscopic Roux-en-Y gastric bypass (LRYGB) versus LSG. METHODS The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was queried for patients undergoing LSG and LRYGB between 2015 and 2017. Univariate analysis and multivariate logistic regression were used to evaluate factors associated with performing LRYGB compared to LSG. RESULTS A total of 252,117 (72.3%) LSG and 96,677 (27.7%) LRYGB cases were identified. Patients undergoing LSG were younger (44.3 ± 12.0 vs 45.2 ± 11.8 years; p < 0.01) and had a lower body mass index (BMI; 45.1 ± 7.8 vs 46.2 ± 8.1 kg/m2; p < 0.01). Most of the patients were females (79.4%), white (73.0%), with an American Society of Anesthesiology (ASA) class ≤ 3 (96.4%). The factors associated with undergoing LRYGB compared to LSG were diabetes mellitus, gastroesophageal reflux disease, BMI ≥ 50 kg/m2, ASA class > 3, obstructive sleep apnea, hypertension, and hyperlipidemia. However, patients with kidney disease, black race, chronic steroid use, age ≥ 60 years, recent smoking history, chronic obstructive pulmonary disease, and coronary artery disease were more likely to undergo LSG. CONCLUSIONS The decision to perform LRYGB is primarily driven by obesity-associated comorbidities and higher BMI, whereas LSG is more likely to be performed in higher risk patients.

Abstract
BACKGROUND Bariatric surgery is an effective treatment for obesity and its associated comorbidities. This is the first comprehensive report of a prospective cohort study, comparing sleeve gastrectomy (SG) with gastric bypass (GB) regarding their effectiveness and safety. METHODS The prospectively collected data of patients, who presented to a specialized bariatric center and underwent a primary bariatric procedure, were compared in terms of weight loss, remission of obesity-associated comorbidities, complication rate, and quality of life improvement at 6-, 12-, and 24-month follow-ups. RESULTS Of 3287 patients (78.6% female) analyzed, 67% (n = 2202) and 33% (n = 1085) underwent SG and GB, respectively. Effective outcomes were reported in both groups regarding the body composition indices. Type 2 diabetes mellitus (T2DM) remission rate at the end of follow-up was 53.3% and 63.8% in the SG and GB groups, respectively. Following the propensity score-adjusted analysis, the T2DM remission rate was not significantly different between the groups. Conversely, the remission rate of hypertension in the 24-month follow-up (39.1% vs. 54.7%) and the remission rate of dyslipidemia in all follow-ups were lower in the SG group, compared to the GB group. Moreover, both procedures caused substantial improvements in various domains of quality of life. The surgery duration, early complication rate, and nutritional deficiencies were lower in the SG group, compared to the GB group. CONCLUSION Both surgical procedures were effective in the control of obesity and remission of its comorbidities. However, since SG was associated with a lower rate of complications, it seems that SG should be considered as a suitable procedure for obese patients, especially those with a healthier metabolic profile.

Abstract
PURPOSE Metabolic syndrome in patients with morbid obesity causes a higher cardiovascular morbidity, eventually leading to left ventricular hypertrophy and decreased left ventricular ejection fraction (LVEF). Roux-en-Y gastric bypass (RYGB) is considered the gold standard modality for treatment of morbid obesity and might even lead to improved cardiac function. Our objective is to investigate whether cardiac function in patients with morbid obesity improves after RYGB. MATERIALS AND METHODS In this single center pilot study, 15 patients with an uneventful cardiac history who underwent RYGB were included from May 2015 to March 2016. Cardiac function was measured by cardiac magnetic resonance imaging (CMRI), performed preoperatively and 3, 6, and 12 months postoperative. LVEF and myocardial mass and cardiac output were measured. RESULTS A total of 13 patients without decreased LVEF preoperative completed follow-up (mean age 37, 48.0 ± 8.8). There was a significant decrease of cardiac output 12 months postoperative (8.3 ± 1.8 preoperative vs. 6.8 ± 1.8 after 12 months, P = 0.001). Average myocardial mass declined by 15.2% (P < 0.001). After correction for body surface area (BSA), this appeared to be non-significant (P = 0.36). There was a significant improvement of LVEF/BSA at 6 and 12 months postoperative (26.2 ± 4.1 preoperative vs. 28.4 ± 3.4 and 29.2 ± 3.6 respectively, both P = 0.002). Additionally, there was a significant improvement of stroke volume/BSA 12 months after surgery (45.8 ± 8.0 vs. 51.9 ± 10.7, P = 0.033). CONCLUSION RYGB in patients with morbid obesity with uneventful history of cardiac disease leads to improvement of cardiac function.

Abstract
BACKGROUND Surgery for obesity and metabolic diseases has been evolved in the light of new scientific evidence, long-term outcomes and accumulated experience. EAES has sponsored an update of previous guidelines on bariatric surgery. METHODS A multidisciplinary group of bariatric surgeons, obesity physicians, nutritional experts, psychologists, anesthetists and a patient representative comprised the guideline development panel. Development and reporting conformed to GRADE guidelines and AGREE II standards. RESULTS Systematic review of databases, record selection, data extraction and synthesis, evidence appraisal and evidence-to-decision frameworks were developed for 42 key questions in the domains Indication; Preoperative work-up; Perioperative management; Non-bypass, bypass and one-anastomosis procedures; Revisional surgery; Postoperative care; and Investigational procedures. A total of 36 recommendations and position statements were formed through a modified Delphi procedure. CONCLUSION This document summarizes the latest evidence on bariatric surgery through state-of-the art guideline development, aiming to facilitate evidence-based clinical decisions.

Abstract
BACKGROUND The sleeve gastrectomy (SG) has gained popularity which has resulted in a rising number of patients with T2DM to undergo this procedure. This systematic review and meta-analysis aimed to compare the long-term effects of SG on T2DM remission with remission seen after Roux-en-Y gastric bypass (RYGB) or gastric banding (GB). METHODS A literature search was performed in PubMed and Cochrane Library using the following search terms: 'sleeve gastrectomy', 'diabetes', 'gastric bypass' and 'gastric banding'. Studies published between January 2000 and April 2018, and with following inclusion criteria were selected for this review: BMI ≥ 35 kg/m2, age ≥ 18 years, follow-up ≥ 1 year, T2DM. Data was statistically analysed using a random-effects model and results were expressed as odds ratio with 95% confidence interval. RESULTS After exclusion, 35 out of an initial 748 studies, consisting of 18 138 T2DM patients, remained for inclusion. Of these patients, 2480 underwent a SG. The remaining patients underwent a RYGB (n = 10,597) or GB (n = 5061). One year postoperatively, SG patients reached significantly (OR 0.71, p = 0.003) less T2DM remission than RYGB. After stratifying for different criteria for remission, RYGB still tended to result in higher remission rates, but the difference was not statistically significant. Beyond 1 year of follow-up, the difference between RYGB and SG in terms of T2DM remission decreased. SG was superior to the GB (OR 2.17, p = 0.001) after 1 year of follow-up. CONCLUSION This review demonstrates important remission of T2DM following SG. Nevertheless, as remission was significantly more often observed following RYGB surgery, the latter procedure remains the gold standard for reaching T2DM remission in patients with concurrent obesity.

Abstract
BACKGROUND Severe obesity is associated with a high prevalence of moderate-to-severe obstructive sleep apnea syndrome (OSA). Bariatric surgery has been shown to effectively reduce excess weight and comorbidities. METHODS We evaluated the remission rate of moderate-to-severe OSA (apnea-hypopnea index (AHI) ≥ 15) following sleeve gastrectomy. We performed a single-center retrospective chart review of all patients who underwent preoperative polysomnography (PSG) or polygraphy before primary sleeve gastrectomy. Patients with moderate-to-severe OSA treated by continuous positive airway pressure (CPAP) also underwent postoperative PSG. Bivariate analysis was performed to evaluate the criteria associated with remission of moderate-to-severe OSA. RESULTS From 2013 to 2018, 39 of 162 patients (24.1%) scheduled for sleeve gastrectomy (SG) presented moderate-to-severe OSA requiring CPAP. Postoperative PSG was performed in 36 patients a mean of 9.9 ± 6.1 months after SG. Mean BMI decreased from 47.4 ± 8.4 to 36.3 ± 7.1 kg/m2 (p < 0.001), and all patients reported clinical improvement of OSA symptoms. A remission of moderate-to-severe OSA was observed in 72.2% of patients with a mean decrease of AHI from 45.8 events/h to 11.3 events/h (p < 0.001). Postoperative neck circumference was the only factor associated with OSA remission. CONCLUSION SG is associated with a rapid improvement of moderate-to-severe OSA partially as a result of a reduction of neck circumference. However, the absence of correlation with excess weight loss suggests that other weight-independent factors may also be involved.

Abstract
Question How do type 2 diabetes (T2DM) outcomes compare across the 2 most common bariatric procedures? Findings In this cohort study of 9710 adults with T2DM who underwent bariatric surgery, most patients who had Roux-en-Y gastric bypass or sleeve gastrectomy experienced T2DM remission at some point over 5 years of follow-up. Patients who had Roux-en-Y gastric bypass showed slightly higher T2DM remission rates, better glycemic control, and fewer T2DM relapse events than patients who had sleeve gastrectomy. Meaning Understanding diabetes outcomes of different bariatric procedures will help surgeons and patients with diabetes make informed health care choices. Importance Bariatric surgery can lead to substantial improvements in type 2 diabetes (T2DM), but outcomes vary across procedures and populations. It is unclear which bariatric procedure has the most benefits for patients with T2DM. Objective To evaluate associations of bariatric surgery with T2DM outcomes. Design, Setting, and Participants This cohort study was conducted in 34 US health system sites in the National Patient-Centered Clinical Research Network Bariatric Study. Adult patients with T2DM who had bariatric surgery between January 1, 2005, and September 30, 2015, were included. Data analysis was conducted from April 2017 to August 2019. Interventions Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Main Outcome and Measures Type 2 diabetes remission, T2DM relapse, percentage of total weight lost, and change in glycosylated hemoglobin (hemoglobin A1c). Results A total of 9710 patients were included (median [interquartile range] follow-up time, 2.7 [2.9] years; 7051 female patients [72.6%]; mean [SD] age, 49.8 [10.5] years; mean [SD] BMI, 49.0 [8.4]; 6040 white patients [72.2%]). Weight loss was significantly greater with RYGB than SG at 1 year (mean difference, 6.3 [95% CI, 5.8-6.7] percentage points) and 5 years (mean difference, 8.1 [95% CI, 6.6-9.6] percentage points). The T2DM remission rate was approximately 10% higher in patients who had RYGB (hazard ratio, 1.10 [95% CI, 1.04-1.16]) than those who had SG. Estimated adjusted cumulative T2DM remission rates for patients who had RYGB and SG were 59.2% (95% CI, 57.7%-60.7%) and 55.9% (95% CI, 53.9%-57.9%), respectively, at 1 year and 86.1% (95% CI, 84.7%-87.3%) and 83.5% (95% CI, 81.6%-85.1%) at 5 years postsurgery. Among 6141 patients who experienced T2DM remission, the subsequent T2DM relapse rate was lower for those who had RYGB than those who had SG (hazard ratio, 0.75 [95% CI, 0.67-0.84]). Estimated relapse rates for those who had RYGB and SG were 8.4% (95% CI, 7.4%-9.3%) and 11.0% (95% CI, 9.6%-12.4%) at 1 year and 33.1% (95% CI, 29.6%-36.5%) and 41.6% (95% CI, 36.8%-46.1%) at 5 years after surgery. At 5 years, compared with baseline, hemoglobin A1c was reduced 0.45 (95% CI, 0.27-0.63) percentage points more for patients who had RYGB vs patients who had SG. Conclusions and Relevance In this large multicenter study, patients who had RYGB had greater weight loss, a slightly higher T2DM remission rate, less T2DM relapse, and better long-term glycemic control compared with those who had SG. These findings can help inform patient-centered surgical decision-making.

Abstract
PURPOSE to assess the long-term benefits of bariatric surgery in super-obese (body mass index [BMI] ≥ 50) and in elderly obese (age > 60 years) populations. METHODS one hundred and twenty one patients who underwent laparoscopic Roux-en-Y gastric bypass or laparoscopic sleeve gastrectomy in a university hospital were retrospectively subdivided into the following groups: BMI < 50 vs ≥ 50 and age < 60 vs ≥ 60 years. Weight loss, body composition and comorbidity outcomes were registered after one and six months and one, two, three and five years with 100%, 93%, 89%, 80%, 75% and 60% successful follow-up. RESULTS the percentage of excess BMI loss (%EBMIL) was comparable between BMI groups and age groups and the difference in the long-term follow up was not statistically significant (p > 0.05). Complication rates, comorbidity resolution, reduction in body fat and increase in fat-free mass were comparable between BMI groups and age groups. Gastric bypass resulted in a greater weight loss compared to sleeve gastrectomy. The % EBMIL was 65.2% vs 46.7% (p = 0.002), 65.8% vs 44.9% (p = 0.004), 64.4% vs 30.5% (p = 0.001), 55.6% vs 17.6% (p = 0.016) at one, two, three and five years postoperative, respectively. Similarly, in the super-obese group, weight loss was more pronounced after gastric bypass versus sleeve gastrectomy. CONCLUSIONS bariatric surgery in super-obese and elderly populations is an effective and safe weight loss measure with a good comorbidity resolution in the long-term. Gastric bypass is superior to sleeve gastrectomy in terms of long-term weight loss and comorbidity resolution in all the groups investigated.

The Effects of Laparoscopic Sleeve Gastrectomy on Glucose Metabolism in Patients with a Body Mass Index below 35 kg/m². MEDICAL BULLETIN OF SISLI ETFAL HOSPITAL 2020; 54:36-40. [PMID: 32377131 PMCID: PMC7192253 DOI: 10.14744/semb.2019.17999] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/22/2019] [Accepted: 11/20/2019] [Indexed: 12/30/2022]
Abstract
Objectives: The prevalence of obesity and its associated comorbidities are increasing all over the world. Laparoscopic sleeve gastrectomy has become the most common bariatric surgery in the world today, especially in the treatment of Type 2 diabetes mellitus, which is one of the effective surgical methods. The present study aims to investigate the effects on glucose metabolism in patients following laparoscopic sleeve gastrectomy. Methods: In this study, the files of 174 patients who had laparoscopic sleeve gastrectomy with a body mass index between 30-35kg/m2 between March 2013 and September 2019 were analyzed retrospectively. Patients were evaluated by a multidisciplinary team in the preoperative period. Patients who met the criteria for laparoscopic sleeve gastrectomy were operated according to American Metabolic and Bariatric Surgeons criteria. Demographic data, body mass index, insulin, glycosylated hemoglobin (HbA1c), glucose, homeostasis model insulin resistance (HOMA-IR) values were recorded. The patients were followed up with visits to the outpatient clinic scheduled for 1-3-6 and 12 months postoperatively. Results: The mean age of the 174 patients who underwent laparoscopic sleeve gastrectomy was 39.57±9.40, and the mean body mass index was 32.70±2.65. 149 patients (85.6%) were female. The mean hospital stay was 3.1±0.7 days. When glucose, HbA1c, HOMAR-IR and insulin values of the patients were examined, it was observed that the decrease was statistically significant at 12 months follow-up. There was a significant decrease in body mass index compared to the preoperative period. Conclusion: Laparoscopic sleeve gastrectomy is an effective surgery on glucose metabolism in patients with a body mass index of 30-35kg/m2.

Abstract
Background Bariatric surgery, such as Roux-en-Y gastric bypass [RYGB] has been shown to be an effective intervention for weight management in select patients. After surgery, different patients respond differently even to the same surgery and have differing weight-change trajectories. The present analysis explores how improving a patient’s post-surgical weight change could impact co-morbidity prevalence, treatment and associated costs in the Canadian setting. Methods Published data were used to derive statistical models to predict weight loss and co-morbidity evolution after RYGB. Burden in the form of patient-years of co-morbidity treatment and associated costs was estimated for a 100-patient cohort on one of 6 weight trajectories, and for real-world simulations of mixed patient cohorts where patients experience multiple weight loss outcomes over a 10-year time horizon after RYGB surgery. Costs (2018 Canadian dollars) were considered from the Canadian public payer perspective for diabetes, hypertension and dyslipidaemia. Robustness of results was assessed using probabilistic sensitivity analyses using the R language. Results Models fitted to patient data for total weight loss and co-morbidity evolution (resolution and new onset) demonstrated good fitting. Improvement of 100 patients from the worst to the best weight loss trajectory was associated with a 50% reduction in 10-year co-morbidity treatment costs, decreasing to a 27% reduction for an intermediate improvement. Results applied to mixed trajectory cohorts revealed that broad improvements by one trajectory group for all patients were associated with 602, 1710 and 966 patient-years of treatment of type 2 diabetes, hypertension and dyslipidaemia respectively in Ontario, the province of highest RYGB volume, corresponding to a cost difference of $3.9 million. Conclusions Post-surgical weight trajectory, even for patients receiving the same surgery, can have a considerable impact on subsequent co-morbidity burden. Given the potential for alleviated burden associated with improving patient trajectory after RYGB, health care systems may wish to consider investments based on local needs and available resources to ensure that more patients achieve a good long-term weight trajectory.

Abstract
Background Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are two representative bariatric surgeries. This study aimed to compare the effects of the LSG and LRYGB based on high-quality analysis and massive amount of data. Methods For this study databases of PubMed, Web of Science, EBSCO, Medline, and Cochrane Library were searched for articles published until January 2019 comparing the outcomes of LSG and LRYGB. Results This study included 28 articles. Overall, 9038 patients (4597, LSG group; 4441, LRYGB group) were included. The remission rate of type 2 diabetes mellitus (T2DM) in the LRYGB group was superior to that in the LSG group at the 3-years follow-up. Five-year follow-up results showed that LRYGB had an advantage over LSG for the percentage of excess weight loss and remission of T2DM, hypertension, dyslipidemia, and abnormally low-density lipoprotein. Conclusions In terms of the long-term effects of bariatric surgery, the effect of LRYGB was better than of LSG.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are widely performed to cure obesity and obesity-related diseases. Our aim was to compare these two procedures. MATERIALS AND METHODS An electronic literature search was performed from inception to December 2018. The clinical outcomes between LSG and LRYGB were pooled using software RevMan5.3. RESULTS A total of 1076 patients from 11 studies were analysed. LSG had shorter operation time (mean difference [MD] = -33.81; 95% confidence interval [CI], -46.04 to -21.57; P < .00001) and less early complications rate (risk ratio [RR] = 0.55; 95% CI, 0.36-0.84; P = .005) compared with LRYGB. There were no significant difference about the readmission rate (RR = 0.57; 95% CI, 0.21-1.54; P = .27) and re-operation rate (RR = 0.43; 95% CI, 0.14-1.27; P = .13) between LSG and LRYGB. The conversion to open rate and mortality rate within 30 days was low in both LSG and LRYGB. Mean hospital stay in LSG group (0.3-5.2 d) seems shorter than that in the LRYGB group (2.3-6.6 d). As to the effect of LSG and LRYGB on the percentage of excess weight loss (EWL), there was no significant difference between these two surgeries in EWL (MD = -4.05; 95% CI, -8.89 to 0.80; P = .10). LSG was equal to LRYGB on remission of T2DM (RR = 0.94; 95% CI, 0.84-1.06; P = .31). CONCLUSIONS Both LSG and LRYGB can be performed with very low conversion to open rate and mortality rate. The readmission rate and re-operation rate are comparable between these two surgeries. The efficacy of these two surgeries on EWL and T2DM is equivalent, but LSG has an advantage over LRYGB in operation time and early complications rate.

Abstract
BACKGROUND The outcomes of bariatric surgery should not be evaluated only for weight loss purposes but from a wider point of view that is closer to the reality of morbidly obese patients. The study of the influence of bariatric surgery over obesity-related diseases in bariatric patients is worthwhile. METHODS We present a cohort study of 329 patients who underwent either laparoscopic sleeve gastrectomy (LSG: 165 patients) or laparoscopic gastric bypass (LRYGBP: 164). We analyzed complication rate, comorbidities and weight loss evolution. RESULTS Both groups were comparable in demographic characteristics at baseline. Significant statistical differences were found in length of hospital stay and operative time (both were lower in the LSG group). Bleeding and wound infection were higher in the LRYGBP group, as it happened with intestinal occlusion as a late complication (p < 0.05). After a 5-year follow-up, the percentage of excess weight loss (%EWL) was higher in gastric bypass than sleeve gastrectomy (p = 0.01) but there was no statistical difference in percentage of total weight loss (%TWL) (p = 0.2). The resolution of comorbidities was similar in both groups except for dyslipidemia, which resolution was significantly higher in the gastric bypass group (p = 0.005). Metabolic syndrome (MeTS) resolution was similar in both groups. CONCLUSIONS Sleeve gastrectomy and gastric bypass achieve similar outcomes in hypertension, type 2 diabetes, obstructive sleep apnea and MeTS resolution even when there is weight regain. Although gastric bypass achieves higher weight loss in morbid obese patients, complication rates are also higher compared to those of sleeve gastrectomy. Thus, the appropriate procedure should be tailored based on patient factors and comorbidities, but also on surgeon comfort level and experience.

Abstract
OBJECTIVES The aim of this study was to determine the efficacy of coaching on outcome in low volume centers of excellence and to evaluate the influence of mentorship programs on the center development. BACKGROUND The number of bariatric procedures has increased steadily in the last years. Providing nationwide bariatric care on a high professional level needs structures to train and guide upcoming centers and ensure high quality in patient care. METHODS A prospective multicentered, observational study including laparoscopic sleeve gastrectomies (SG) and Roux-en-Y gastric bypass (RYGB) procedures was performed. Twelve emerging bariatric centers were coached by five experienced bariatric centers. Surgeons of the mentor centers gave guidance on pre- and postsurgical management of their patients including complications and proctored the first interventions. The results were compared regarding operative outcomes, percentage of excess weight loss, complications, and resolution of comorbidities. RESULTS A total of 214 of 293 patients (73.0%) completed the study. The most frequently reported complications were wound infection (4.4%), disorder of emptying stomach/new reflux (2.4%), anastomotic leaks, intra-abdominal secondary hemorrhage, and dumping syndrome (2.0% each). The mortality rate was zero. We found no difference in overall complication rates or resolution of obesity-related comorbidities when comparing experienced surgeons with less experienced surgeons. CONCLUSIONS Our results suggest that under the conditions of the practices of this study, coaching and mentoring were associated with comparable outcomes both in experienced and emerging centers. In addition, mentorship programs ensure equal outcome quality in terms of improvement of obesity-associated comorbidities. TRIAL REGISTRATION NCT Number: NCT01754194 .

Abstract
BACKGROUND Obesity and type 2 diabetes mellitus (T2DM) are now increasingly epidemic in Asia. As obesity and T2DM have different disease patterns in Asians compared to Westerners, outcomes after metabolic surgery may differ. The aim of this meta-analysis was to gather the current available evidence on the outcomes after metabolic surgery in Asians. METHODS A literature search was conducted in September 2017. Four outcome measures were examined: (1) % excess weight loss (EWL), (2) post-intervention body mass index (BMI), (3) T2DM resolution or improvement, and (4) hypertension resolution. RESULTS Thirteen publications with a total of 1052 patients were analyzed, of which nine were randomized controlled trials, and four were case-matched studies. All the studies had a minimum follow-up duration of at least 1 year. % EWL was significantly higher in those who have undergone Roux-en-Y gastric bypass (RYGB) (SMD 0.53, 95% CI 0.12 to 0.94) versus sleeve gastrectomy (SG). T2DM resolution/improvement was favorable in those who have undergone RYGB (pooled OR 1.39, 95% CI 0.53 to 3.67) versus SG, although not statistically significant. Hypertension resolution was not significantly different between patients who have undergone SG versus RYGB (pooled OR 0.96, 95% CI 0.44 to 2.11). CONCLUSION RYGB results in better weight loss compared to SG in Asians, but the rate of T2DM resolution/improvement and improvement of hypertension appears to be similar. In Asian patients without symptoms of gastro-esophageal reflux disease in whom metabolic surgery is performed mainly for T2DM and metabolic syndrome, SG may be the surgery of choice.

Abstract
IMPORTANCE Information on the associations between barriers to delivery of bariatric surgery and poor weight trajectory afterward is lacking. Estimates are needed to inform decisions by administrators and clinicians to improve care. OBJECTIVE To estimate the difference in patient-years of treatment for diabetes, hypertension, and dyslipidemia and public-payer cost between the Canadian standard and an improved bariatric surgery care pathway. DESIGN, SETTING, AND PARTICIPANTS Economic evaluation of a decision analytic model comparing the outcomes of the standard care in Canada with an improved bariatric care pathway with earlier sleeve gastrectomy delivery and better postsurgical weight trajectory. The model was informed by published clinical data (101 studies) and meta-analyses (11 studies) between January and May 2019. Participants were a hypothetical 100-patient cohort with demographic characteristics derived from a Canadian study. INTERVENTIONS Reduction of Canadian mean bariatric surgery wait time by 2.5 years following referral and improvement of patient postsurgery weight trajectory to levels observed in other countries. MAIN OUTCOMES AND MEASURES Modeling weight trajectory after sleeve gastrectomy and resolution rates for comorbidities in Canada in comparison with an improved care pathway to estimate differences in patient-years of comorbidity treatment over 10 years following referral and the associated costs. RESULTS For the 100-patient cohort (mean [SD] 88.2% [1.4%] female; mean [SD] age, 43.6 [9.2] years; mean [SD] body mass index, 49.4 [8.2]; and mean [SD] comorbidity prevalence of 50.0% [4.1%], 66.0% [3.9%], and 59.3% [4.0%] for diabetes, hypertension, and dyslipidemia, respectively) over 10 years following referral, the improved vs standard care pathway was associated with median reduction in patient-years of treatment of 324 (95% credibility interval [CrI], 249-396) for diabetes, 245 (95% CrI, 163-356) for hypertension, and 255 (95% CrI, 169-352) for dyslipidemia, corresponding to total savings of $900 000 (95% CrI, $630 000 to $1.2 million) for public payers in the base case. Relative to standard of care, the associated reduction in costs was approximately 29% (95% CrI, 20%-42%) in the improved pathway. Sensitivity analyses demonstrated independent associations of earlier surgical delivery and various levels of postsurgical weight trajectory improvements with overall savings. CONCLUSIONS AND RELEVANCE This study suggests that health care burden may be decreased through improvements to delivery and management of patients undergoing sleeve gastrectomy. More data are needed on long-term patient experience with bariatric surgery in Canada to inform better estimates.

Abstract
BACKGROUND Super obesity (BMI ≥ 50 kg/m2) is associated with significant morbidity and mortality. The best procedure to treat super obesity is not completely established. Our aim was to compare the effectiveness of bariatric procedures (adjustable gastric band [AGB], Roux-en-Y gastric bypass [RYGB], sleeve gastrectomy [SG]) in super obesity. METHODS Retrospective observational study of super obese patients who underwent bariatric surgery. Data was assessed preoperatively and in the 1st and 2nd years of follow-up. RESULTS We evaluated 213 individuals, 77.9% female, age of 43.38 ± 11.49 years, and preoperative BMI of 54.53 ± 4.54 kg/m2; 19 submitted to AGB, 127 to RYGB, and 67 to SG. In the pre-surgical assessment, there were no significant differences in age, anthropometric parameters, blood pressure, glycemic profile, and lipid profile between the three surgical groups. The percentage of excess weight loss (%EWL) in the 1st year was 67.58% in RYGB, 58.74% in SG, and 38.71% in AGB (p < 0.001), and the percentage of total weight loss (%TWL) was 36.29%, 31.59%, and 21.07%, respectively (p < 0.001). Two years after surgery (n = 147; follow-up rate of 69%), the %EWL and %TWL were significantly higher in the RYGB group (p < 0.001). RYGB had a higher success rate (%EWL ≥ 50% and %TWL ≥ 20%) in both years of follow-up (p < 0.001). In multiple linear regression, after adjusting for other covariates, RYGB was the only strong predictive factor of %EWL and %TWL (p < 0.001). CONCLUSION RYGB proved to be more effective in super obesity. The beneficial effects in weight loss were evident both 1 and 2 years after the procedure, regardless of pre-surgical anthropometric characteristics.

Abstract
BACKGROUND Improvement of dyslipidemia is an important benefit of bariatric surgery. The benefits of laparoscopic sleeve gastrectomy (LSG) among dyslipidemia are still a matter of debate. METHODS We conducted a retrospective descriptive study between 2010 and 2013. Obese patients undergoing LSG, with recorded dyslipidemia at admission and a follow-up for at least 1 year, were included for analysis. Demographic characteristics, medication in use, and a complete lipid profile were collected before surgery. After surgery, weight was controlled at 1, 3, 6, and 12 months. Lipid profile was re-evaluated 1 year after surgery. Patients were divided according to weight loss into two groups: (A) adequate weight loss and (B) inadequate weight loss. Lipid profile evolution was then compared between groups. RESULTS One hundred seven patients met the inclusion criteria. Pre-op mean BMI was 45.13 ± 7.5 kg/m2. One year after LSG, mean BMI was 30.6 ± 7.1 kg/m2 with a change in BMI of 11.5 ± 6.6 kg/m2, a %TWL of 26.9 ± 13.5%, and a %EWL of 60.3 ± 36.6%. Hypercholesterolemia and hypertriglyceridemia remission was achieved in 45 and 86% of the patients and improved in another 19 and 4% respectively. Seventy-four percent improved HDL levels. LDL levels improved in 39% and remitted in 37%. Medication was discontinued in 43.7%. HDL increase and LDL, TG, and non-HDL-C decrease were significantly greater in group A. CONCLUSIONS LSG produces an improvement in lipid profile, with a significant increase in HDL and a decrease in LDL, triglycerides, and non-HDL-C.

Abstract
BACKGROUND One of the new current treatment options for Diabetes Mellitus is about increasing glucagon-like peptide-1 (GLP-1) activity. GLP-1 with its incretin effect showed major role in glucose homeostasis. Gastroileostomy can increase GLP-1 secretion by rapid delivery of undigested food to the terminal ileum. We studied the early effects of a gastroileostomy on serum levels of GLP-1, glucose, and insulin in rats. METHODS Gastroileostomies with side-to-side anastomosis were performed on 15 male New Zealand rats. Blood samples were obtained before and 1 week after the gastroileostomy. RESULTS Our results showed that the rats lost a lot of weight from start (330 ± 15 g) to the end (240 ± 25 g) of the experiment (p = 0.048). The data analysis showed that the gastroileostomy surgery elevates the level of GLP-1in plasma significantly (89.1852 vs. 177.440 respectively; p < 0.001) and caused a significant decrease in plasma glucose as well (92.00 and 66.29 mg/dL respectively; p < 0.001). However, the insulin state elevated after the surgery significantly (8.03 vs. 9.89; p < 0.001). CONCLUSION In this study, we showed the effectiveness of gastroileostomy treatment to decrease body weight and plasma glucose with increased GLP-1 in rats. This small rat model suggests the potential of this surgery to treat type 2 diabetes mellitus.

Abstract
INTRODUCTION The long-term results in sleeve gastrectomy (SG) have been reported in few publications. None of them has evaluated the importance of preoperative BMI (kg/m2) in the final results. OBJECTIVE To determine the loss and regain of weight after SG, determining the influence of preoperative BMI in final results. MATERIAL AND METHODS This prospective study included all patients operated between 2006 and 2010. Exclusion criteria corresponded to patients with Barrett's esophagus, type 2 diabetes, and hiatal hernia greater than 3 cm. Patients were followed and controlled "face to face" by the main author. RESULTS From 109 original patients included in this study, 102 (93.5%) completed the late follow-up. Patients were divided into four groups: (a) I-29 patients with BMI 32.1-34.9; (b) II-56 patients with BMI 35-39.9; (c) III-20 patients with BMI 40-49.9; and (d) IV-4 patients with BMI > 50. There was a significant decrease in the BMI 12 to 24 months after surgery. At the late control, patients in groups III and IV regained weight in 85 and 100%, respectively. Patients in groups I and II had 3.6 and 38% of weight regain. CONCLUSION The changes in weight after SG are directly related to preoperative BMI: the higher this value, the higher the percentage of failure and weight regain late after surgery. Besides, laparoscopic SG seems to be an adequate operation at late control in terms of loose of weight after surgery in patients with a BMI less than 40 kg/m2 before surgery.

Abstract
BACKGROUND Sleeve gastrectomy (LSG) is now the predominant bariatric surgery performed, yet there is limited long-term data comparing important outcomes between LSG and Roux-en-Y gastric bypass (RYGB). This study compares weight loss and impact on comorbidities of the two procedures. METHODS We retrospectively evaluated weight, blood pressure, hemoglobin A1c, cholesterol, and medication use for hypertension, diabetes, and hyperlipidemia at 1-4 years post-operatively in 380 patients who underwent RYGB and 334 patients who underwent LSG at the University of Michigan from January 2008 to November 2013. Follow-up rates from 714 patients initially were 657 (92%), 556 (78%), 507 (71%), and 498 (70%) at 1-4 years post-operatively. RESULTS Baseline characteristics were similar except for higher weight and BMI in LSG. There was greater weight loss with RYGB vs. LSG at all points. Hemoglobin A1c and total cholesterol improved more in RYGB vs. LSG at 4 years. There was greater remission of hypertension and discontinuation of all medications for hypertension and diabetes with RYGB at 4 years. CONCLUSIONS Weight loss, reduction in medications for hypertension and diabetes, improvements in markers of diabetes and hyperlipidemia, and remission rates of hypertension were superior with RYGB vs. LSG 4 years post-operatively. Choice of bariatric procedures should be tailored to surgical risk, comorbidities, and weight loss goals.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) is a serious obesity-associated disorder that causes significant short- and long-term medical consequences. OBJECTIVE The objective of this study is to compare the 6-month and 1-year postoperative symptomatic OSA remission rates of patients undergoing bariatric surgery based on their preoperative body mass index (BMI) stratification, type of bariatric operation-sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB)-and OSA severity. METHODS We retrospectively analyzed 297 obese patients with a diagnosis of OSA who had undergone either SG or RYGB between 2011 and 2015. RESULTS The overall 6-month symptomatic OSA remission rate for patients (n = 255) was 74.5%. At 6 months, patients with a preoperative BMI of 30-34.9 kg/m2 (class I), 35-39.9 kg/m2 (class II), and 40+ kg/m2 (class III) had 100, 70.0, and 75.0% (p = 0.2164) remission rates, respectively. The 6-month remission rates for SG and RYGB were 75.3 and 70.8% (p = 0.5165), respectively. The overall 1-year symptomatic OSA remission rate for patients (n = 162) was 87.1%. At 1 year, class I, II, and III patients had 100, 85.7, and 87.5% (p = 0.5740) remission rates, respectively. The 1-year remission rates for SG and RYGB were 89.2 and 81.2% (p = 0.2189), respectively. A sub-analysis (n = 69) based on preoperative OSA severity levels did not affect the remission outcome at either the 6-month (p = 0.3670) or 1-year (p = 0.3004) follow-up. CONCLUSION Most obese patients experience symptomatic remission of their OSA after bariatric surgery, regardless of their preoperative BMI, choice of operation, or OSA severity.

Abstract
Bariatric surgery is an efficient treatment for weight loss in obese patients and for resolving obesity comorbidities. However, the mechanisms behind these outcomes are unclear. Recent studies have indicated significant alterations in the transcriptome after surgery, specifically in the differential expression of microRNAs. In order to summarize the recent findings, we conducted a systematic summary of studies comparing microRNA expression levels before and after surgery. We identified 17 animal model and human studies from four databases (Ovid, Scopus, Web of Science, and PubMed) to be enrolled in this meta-analysis. From these studies, we identified 14 miRNAs which had the same direction of modulation of their expression after surgery in at least two studies (downregulated: hsa-miR-93-5p, hsa-miR-106b-5p, hsa-let-7b-5p, hsa-let-7i-5p, hsa-miR-16-5p, hsa-miR-19b-3p, hsa-miR-92a-3p, hsa-miR-222-3p, hsa-miR-142-3p, hsa-miR-140-5p, hsa-miR-155-5p, rno-miR-320-3p; upregulated: hsa-miR-7-5p, hsa-miR-320c). Pathway analysis for these miRNAs was done using database resources (DIANA-TarBase and KEGG pathway database) and their predicted target genes were discussed in relation with obesity and its comorbidities. Discrepancies in study design, such as miRNA source, bariatric surgery type, time of observation after surgery, and miRNA profiling methods, were also discussed.

Abstract
OBJECTIVE Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are commonly performed weight loss procedures worldwide. Unfortunately, few studies have compared percentage total weight loss (%TWL) following these procedures. This research compared short-term, mid-term and long-term %TWL by LRYGB and LSG. METHODS Selected databases were searched for original articles that compared %TWL by LSG and LRYGB. Review manager 5.3 was used for data analysis. Effect summary was presented by forest plot. RESULTS A significantly better %TWL in 5 years was shown by LRYGB than LSG; pooled mean difference (MD) 1.87 (95% CI 0.27-3.48, z statistics = 2.28, p < 0.05). Subgroup analysis showed better %TWL by LRYGB than LSG at 24 months pooled MD 6.47 (95% CI 1.22-11.72, z statistics = 2.42, p < 0.05), however, better %TWL by LSG was noted after 36 months (pooled MD -0.23; 95% CI -0.39-0.06, z statistics = 2.65, p < 0.05). Finally, significantly better %TWL was noted for LRYGB at 60 months. CONCLUSION This study shows %TWL of 70.4% by LRYGB and 59.8% following LSG in at least half of patients from selected cohort. A significantly greater %TWL by LRYGB in short and long term, while higher %TWL by LSG in mid-term is reported.

Abstract
INTRODUCTION Contrary to published literature, our institutional data demonstrated reduced weight loss following laparoscopic sleeve gastrectomy (LSG) compared to gastric bypass (LRYGB). The purpose of this study was to determine if known predictors of poor weight loss accounted for this discrepancy at a large volume center. METHODS All patients undergoing primary LSG (n = 322) and LRYGB (n = 249), from 2014 to 2016, at a single institution were retrospectively reviewed. Baseline medical, socioeconomic, and follow-up data (6, 12, 24, and 36 months) were obtained. The first aim characterized differences in LSG and LRYGB. The second objective determined predictors of experiencing the lowest or highest quartile of excess body weight loss [(EBWL), (%EBWL-25th, %EBWL-75th)] at 12, 24, and 36 months. Thirdly, predictors of poor weight loss within sleeve gastrectomy were characterized. RESULTS In comparison to patients undergoing LRYGB, LSG patients demonstrated lower baseline BMI (47.9 ± 8.2 vs. 51.5 ± 10.1, p < 0.0005), lower incidences of obesity-related comorbidities (p < 0.05), were more likely to have higher education (p = 0.02), and were associated with no-shows up to 2 years post-operatively. LSG remained a strong independent predictor of %EBWL-25th at 12 months (OR = 5.2, p < 0.005), 24 months (OR = 5.3, p < 0.005), and 36 months (OR = 7.3, p = 0.006), after adjusting for comorbidities, education, and no-shows. Predictors of poor weight loss after LSG included hypertension, African American race, major depression, no-shows at 6 and 12 months. Within patients associated with these characteristics, the relative risk of experiencing poor weight loss was significantly higher following LSG compared to LRYGB at 12 months (60% vs. 25.0%, p < 0.05), 24 months (43% vs. 18%, p < 0.05), and 36 months (70% vs. 21%, p < 0.05). CONCLUSIONS LSG remained an independent predictor of poor weight loss at all post-operative time points. Furthermore, the risk of experiencing poor weight loss was significantly higher following LSG compared to LRYGB for patients with high-risk characteristics.

Abstract
BACKGROUND & AIMS Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) induce substantial weight loss and improve glycemic control in patients with type 2 diabetes, but it is not clear whether these occur via the same mechanisms. We compared absorption rates of glucose and protein, as well as profiles of gastro-entero-pancreatic hormones, in patients who had undergone SG or RYGB vs controls. METHODS We performed a cross-sectional study of 12 patients who had undergone sleeve gastrectomy, 12 patients who had undergone RYGB, and 12 individuals who had undergone neither surgery (controls), all in Denmark. Study participants were matched for body mass index, age, sex, and postoperative weight loss, and all had stable weights. They received continuous infusions of stable isotopes of glucose, glycerol, phenylalanine, tyrosine, and urea before and during a mixed meal containing labeled glucose and intrinsically phenylalanine-labeled caseinate. Blood samples were collected for 6 hours, at 10- to 60-minute intervals, and analyzed. RESULTS The systemic appearance of ingested glucose was faster after RYGB and SG vs controls; the peak glucose appearance rate was 64% higher after RYGB, and 23% higher after SG (both P < .05); the peak phenylalanine appearance rate from ingested casein was 118% higher after RYGB (P < .01), but similar between patients who had undergone SG and controls. Larger, but more transient increases in levels of plasma glucose and amino acids were accompanied by higher secretion of insulin, glucagon-like peptide 1, peptide YY, and cholecystokinin after RYGB, whereas levels of ghrelin were lower after SG, compared with RYGB and controls. Total 6-hour oral recovery of ingested glucose and protein was comparable among groups. CONCLUSIONS Postprandial glucose and protein absorption and gastro-entero-pancreatic hormone secretions differ after SG and RYGB. RYGB was characterized by accelerated absorption of glucose and amino acids, whereas protein metabolism after SG did not differ significantly from controls, suggesting that different mechanisms explain improved glycemic control and weight loss after these surgical procedures.

Abstract
BACKGROUND It is unclear whether bariatric surgery affects the risk of drug- and alcohol-related mortality. OBJECTIVES To compare the observed drug- and alcohol-related mortality rate with age, sex, race, and year-adjusted rates from the general U.S. POPULATION SETTING The Longitudinal Assessment of Bariatric Surgery-2, a prospective cohort study of 2458 adults who underwent bariatric surgery at 10 U.S. hospitals between April 2006 and April 2009. METHODS Participants attended presurgery and annual postsurgery assessments for up to 7 years. Drug- and alcohol-related standardized mortality ratios (SMR) comparing the observed post-bariatric surgery mortality rate with the age, sex, race, and year-adjusted expected mortality rate from the general U.S. population, among the entire cohort, and among those who underwent Roux-en-Y gastric bypass (RYGB). RESULTS Ten deaths related to drug or alcohol use (6 accidental overdose, 1 intentional overdose, 1 intent unknown overdose, and 2 alcoholic liver disease) occurred across 15,616 person-years of follow-up, all among participants who underwent RYGB (n = 1770). The observed mortality rate was significantly higher than expected for all drug- and alcohol-related causes overall (SMR = 2.10, 95% confidence interval = 1.01-3.86, P = .03) and among participants who underwent RYGB (SMR = 2.90, 95% confidence interval = 1.39-5.33, P = .003). The RYGB SMRs were significant for all overdoses (P = .002) and accidental overdoses (P = .01) and in the same direction but nonsignificant for intentional overdoses, intent unknown overdoses, and alcoholic liver disease (P for all ≥. 05). CONCLUSIONS Drug- and alcohol-related mortality is significantly higher than expected in the 7 years after bariatric surgery, specifically after RYGB.

Abstract
BACKGROUND Sleeve gastrectomy (SG) is one of the most effective treatments for severe obesity, but weight regain after surgery is a challenging issue. The mechanism of postoperative weight relapse is barely understood because of the lack of long-term data. OBJECTIVES To review and synthesize current evidence related to factors that contribute to weight regain after SG. METHODS Whittemore and Knafl's integrative method guided the research. The databases PubMed, EMBASE, and CINAHL, as well as 2 selected journals, were searched through October 2018 to gather English-language journal articles on the potential predictors of post-SG weight regain among adult populations. Only articles with sample size ≥10 were included. A narrative synthesis was used to analyze the 17 studies included in the review. RESULTS In recent years there has been an upward trend in the published reports of SG on longer-term outcomes. After a review of 6863 records, 17 eligible studies were identified, reporting various definitions of weight regain and 3 main categories of predictors: surgical/anatomic factors, hormonal/metabolic imbalance, and behavioral/mood factors. The 17 studies used quantitative (n = 16) and qualitative methods (n = 1). CONCLUSION There is a dearth of available literature addressing predictors of weight regain after SG, and the inconsistency in the definition of regain limited the comparability between studies. Besides the surgical/anatomic factors that have been reported as significant predictors, other modifiable factors such as behavioral and psychosocial determinants need to be further investigated.

Abstract
BACKGROUND Bariatric surgery can lead to changes in the oral absorption of many drugs. Levothyroxine is a narrow therapeutic drug for hypothyroidism, a common condition among patients with obesity. OBJECTIVE The purpose of this work was to provide a mechanistic overview of levothyroxine absorption, and to thoroughly analyze the expected effects of bariatric surgery on oral levothyroxine therapy. METHODS We performed a systematic review of the relevant literature reporting the effects of bariatric surgery on oral levothyroxine absorption and postoperative thyroid function. A PubMed search for relevant keywords resulted in a total of 14 articles reporting levothyroxine status before versus after bariatric surgery. RESULTS Different mechanisms may support opposing trends as to levothyroxine dose adjustment postsurgery. On the one hand, based on impaired drug solubility/dissolution attributable to higher gastric pH as well as reduced gastric volume, compromised levothyroxine absorption is expected. On the other hand, the great weight loss, and altered set-point of thyroid hormone homeostasis with decreased thyroid-stimulating hormone after the surgery, may result in a decreased dose requirement. CONCLUSIONS For patients after bariatric surgery, close monitoring of both the clinical presentation and plasma thyroid-stimulating hormone and T4 levels is strongly advised. Better understanding and awareness of the science presented in this article may help to avoid preventable complications and provide optimal patient care.

Abstract
INTRODUCTION Bariatric surgery is an effective treatment for morbid obesity and its metabolic related comorbidities. However, the literature reports inconsistent results regarding weight loss (WL) and the resolution of comorbidities associated with obesity. OBJECTIVE We aim to evaluate long-term differences in WL between different surgical techniques and the impact of each surgical technique on metabolic parameters (type 2 diabetes mellitus [T2DM], dyslipidemia,hypertension, and metabolic syndrome). We also aim to evaluate the effect of baseline clinical characteristics in WL and in the evolution of metabolic syndrome (MetS) components. Our hypothesis is that different types of surgery have different effects on WL and the prevalence of comorbidities over time. METHODS We retrospectively evaluated WL and metabolic parameter remission (T2DM, dyslipidemia, hypertension, and MetS) during 4 years in 1,837 morbidly obese patients (females, 85%; age, 42.5 ± 10.6 years; BMI, 44.0 ± 5.8) who underwent bariatric surgery (Roux-en-Y gastric bypass [RYGB], laparoscopic sleeve gastrectomy [LSG], and laparoscopic adjustable gastric band [LAGB]). RESULTS The mean percentage of WL for RYGB, LSG, and LAGB was, respectively, 32.9 ± 8.7, 29.8 ± 9.8, and 16.2 ± 9.6 at 12 months and 30.6 ± 9.1, 22.7 ± 10.0, and 15.8 ± 10.8 at 48 months (p < 0.001), even after adjustment for baseline weight, BMI, age, and sex (p < 0.001). Women had more WL during the first 36 months (p = 0.013 and 0.007 at 12 and 36 months, respectively) and older patients had less WL compared to younger ones (p <0.001), except at 48 months. Patients with T2DM had less WL than those without diabetes after adjustment (sex, age, and surgical technique) during the same period. Patients with hypertension had less WL at 12 months (p = 0.009) and MetS at 24 months (p = 0.020) compared to those without these comorbidities. There was no significant difference regarding the presence of dyslipidemia in WL. The RYGB group showed better results for MetS resolution. CONCLUSION During the 4-year follow-up, RYGB was the surgical procedure that caused the highest WL and MetS resolution.

Abstract
BACKGROUND There has been a dramatic shift in use of bariatric procedures, but little is known about their long-term comparative effectiveness. OBJECTIVE To compare weight loss and safety among bariatric procedures. DESIGN Retrospective observational cohort study, January 2005 to September 2015. (ClinicalTrials.gov: NCT02741674). SETTING 41 health systems in the National Patient-Centered Clinical Research Network. PARTICIPANTS 65 093 patients aged 20 to 79 years with body mass index (BMI) of 35 kg/m2 or greater who had bariatric procedures. INTERVENTION 32 208 Roux-en-Y gastric bypass (RYGB), 29 693 sleeve gastrectomy (SG), and 3192 adjustable gastric banding (AGB) procedures. MEASUREMENTS Estimated percent total weight loss (TWL) at 1, 3, and 5 years; 30-day rates of major adverse events. RESULTS Total numbers of eligible patients with weight measures at 1, 3, and 5 years were 44 978 (84%), 20 783 (68%), and 7159 (69%), respectively. Thirty-day rates of major adverse events were 5.0% for RYGB, 2.6% for SG, and 2.9% for AGB. One-year mean TWLs were 31.2% (95% CI, 31.1% to 31.3%) for RYGB, 25.2% (CI, 25.1% to 25.4%) for SG, and 13.7% (CI, 13.3% to 14.0%) for AGB. At 1 year, RYGB patients lost 5.9 (CI, 5.8 to 6.1) percentage points more weight than SG patients and 17.7 (CI, 17.3 to 18.1) percentage points more than AGB patients, and SG patients lost 12.0 (CI, 11.6 to 12.5) percentage points more than AGB patients. Five-year mean TWLs were 25.5% (CI, 25.1% to 25.9%) for RYGB, 18.8% (CI, 18.0% to 19.6%) for SG, and 11.7% (CI, 10.2% to 13.1%) for AGB. Patients with diabetes, those with BMI less than 50 kg/m2, those aged 65 years or older, African American patients, and Hispanic patients lost less weight than patients without those characteristics. LIMITATION Potential unobserved confounding due to nonrandomized design; electronic health record databases had missing outcome data. CONCLUSION Adults lost more weight with RYGB than with SG or AGB at 1, 3, and 5 years; however, RYGB had the highest 30-day rate of major adverse events. Small subgroup differences in weight loss outcomes were observed. PRIMARY FUNDING SOURCE Patient-Centered Outcomes Research Institute.

Abstract
BACKGROUND Sleeve gastrectomy (SG) has become the most performed bariatric procedure to induce weight loss worldwide. Unfortunately, a significant portion of patients show insufficient weight loss or weight regain after a few years. OBJECTIVE To investigate the effectiveness of the single anastomosis duodenoileal (SADI) bypass versus the Roux-en-Y gastric bypass (RYGB) on health outcomes in morbid obese patients who had undergone SG previously, with up to 2 years of follow-up. METHODS From 2007 to 2017, 140 patients received revisional laparoscopic surgery after SG in four specialized Dutch bariatric hospitals. Data was analyzed retrospectively and included comparisons for indication of surgery, vitamin/mineral deficiencies, and complications; divided into short-, medium-term. To compare weight loss, linear regression and linear mixed models were used. RESULTS Conversion of a SG to SADI was performed in 66 patients and to RYGB in 74 patients. For patients in which additional weight loss was the main indication for surgery, SADI achieved 8.7%, 12.4%, and 19.4% more total body weight loss at 6, 12, and 24 months compared to RYGB (all p < .001). When a RYGB was indicated in case of gastroesophageal reflux or dysphagia, it greatly reduced complaints almost directly after surgery. Furthermore, a similar amount of complications and nutritional deficiencies was observed for both groups. There was no intra- or post-operative mortality. CONCLUSION Conversion into a SADI resulted in significantly more weight loss while complications rates and nutritional deficiencies were similar and may therefore be considered the recommended operation for patients in which only additional weight loss is required.

Abstract
BACKGROUND Data from a US multicenter longitudinal study of bariatric surgery were used to compare weight change (primary outcome) and comorbidities (secondary outcome) in patients who underwent sleeve gastrectomy versus Roux-en-Y gastric bypass. METHODS This study includes participants who underwent sleeve gastrectomy and matched participants who underwent Roux-en-Y gastric bypass from the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2) study. Adults undergoing initial bariatric surgical procedures between 2006 and 2009 were enrolled. Participants who underwent sleeve gastrectomy were high-risk or superobese and intended to have a second-stage procedure. Mixed models were used to evaluate percent weight change from baseline through 7 years, and diabetes, dyslipidemia, and hypertension prevalence through 5 years. RESULTS Fifty-seven of 59 participants who underwent sleeve gastrectomy were matched one to one. Most were female (68%) and white (81%), and had a median age of 49 (37-56) years and median body mass index of 56.4 (35.5-76.8) kg/m2 presurgery. Weight loss was significantly less 1 to 7 years after sleeve gastrectomy versus matched Roux-en-Y gastric bypass (eg, year 7 mean weight loss was 23.6% vs 30.4%, respectively; P = .001). For both surgical groups, prevalence of diabetes, low high-density lipoprotein, and hypertension were significantly (P < .05) lower 5 years postsurgery versus baseline. CONCLUSION Higher-risk or super-obese participants after sleeve gastrectomy lost less weight than did matched Roux-en-Y gastric bypass counterparts throughout 7 years. Both groups exhibited improvements in comorbidities from presurgery through 5 years.

Abstract
Background Laparoscopic metabolic surgery has been previously shown to be an effective treatment for obese patients with type 2 diabetes (T2DM). The objective of this scoping review is to determine the impact of metabolic surgery for the treatment of type 2 diabetes in Asia and perform an evidence-based analysis. Methods We performed a literature search in PubMed for research on laparoscopic metabolic surgery for the treatment of T2DM in Asia region. We classified the included studies based on the Oxford Center for Evidence Based Medicine guidelines. And performed and evidence analysis. Results In total, 205 articles were identified. 62.9% of the studies were from East Asia. The evidence of 26 studies are level I, 59 are level II. Laparoscopic sleeve gastrectomy (LSG) was the most commonly reported surgical procedure (63.1%) in Asia. The number of laparoscopic metabolic surgery for T2DM in Asian countries has increased rapidly over the last 8 years. We identified 16 studies which showed that laparoscopic metabolic surgery is an effective and safe treatment for T2DM in patients with a BMI of > 25 kg/m2 to < 35 kg/m2 in Asia. Conclusions Our results suggest that laparoscopic metabolic surgery might be an effective and safe treatment for T2DM patients with BMI < 35 kg/m2, and that LSG is the most commonly performed surgical procedure for this in Asia.

Surg Obes Relat Dis 2018; 14:1822-1831.

Abstract
Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are the most commonly performed bariatric procedures globally. However, it remains controversial which procedure provides better glycemic control. To identify predictors of glycemic control after SG versus RYGB, a systematic search of PubMed, EMBASE, and the Cochrane Library was conducted up to January 2017 for comparative studies with both SG and RYGB arms for the treatment of type 2 diabetes (T2D). A meta-analysis and systematic review was performed to evaluate glycemic control after SG versus RYGB with both short- and long-term follow-up. A meta-regression was performed to evaluate impacts of clinical indicators on glycemic control after SG versus RYGB. A total of 17 comparative studies involving 1160 patients were included. SG and RYGB achieved similar diabetic remission rates with both short- and long-term follow-up. However, SG provided lower endpoint glycosylated hemoglobin (A1C) after 1-year follow-up (mean deviation = .17, 95% confidence interval .03-.31, P = .02). When adjusted by baseline A1C, SG and RYGB provided similar percent delta A1C with 1-, 2-, 3-, and 5-year follow-up. The baseline body mass index, duration of T2D, preoperative fasting plasma glucose, and preoperative A1C had predictive value for glycemic control after SG, but only duration of T2D and preoperative A1C were correlated with that after RYGB. These findings showed that the choice of procedure between SG and RYGB predicts no better glycemic control. However, more factors should be considered when SG is recommended to a given patient with diabetes.
