Thanos PK, Hanna C, Mihalkovic A, Hoffman AB, Posner AR, Busch J, Smith C, Badgaiyan RD, Blum K, Baron D, Mastrandrea LD, Quattrin T. The First Exploratory Personalized Medicine Approach to Improve Bariatric Surgery Outcomes Utilizing Psychosocial and Genetic Risk Assessments: Encouraging Clinical Research. J Pers Med 2023; 13:1164. [PMID: 37511777 PMCID: PMC10381606 DOI: 10.3390/jpm13071164] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 07/06/2023] [Accepted: 07/10/2023] [Indexed: 07/30/2023] Open
Abstract
It is predicted that by 2030, globally, an estimated 2.16 billion adults will be overweight, and 1.12 billion will be obese. This study examined genetic data regarding Reward Deficiency Syndrome (RDS) to evaluate their usefulness in counselling patients undergoing bariatric surgery and gathered preliminary data on the potential use in predicting short term (6-month) weight loss outcomes. Methods: Patients undergoing bariatric surgery (n = 34) were examined for Genetic Addiction Risk Severity (GARS) [measures the presence of risk alleles associated with RDS]; as well as their psychosocial traits (questionnaires). BMI changes and sociodemographic data were abstracted from Electronic Health Records. Results: Subjects showed ∆BMI (M = 10.0 ± 1.05 kg/m2) and a mean % excess weight loss (56 ± 13.8%). In addition, 76% of subjects had GARS scores above seven. The homozygote risk alleles for MAO (rs768062321) and DRD1 (rs4532) showed a 38% and 47% prevalence among the subjects. Of the 11 risk alleles identified by GARS, the DRD4 risk allele (rs1800955), was significantly correlated with change in weight and BMI six months post-surgery. We identified correlations with individual risk alleles and psychosocial trait scores. The COMT risk allele (rs4680) showed a negative correlation with EEI scores (r = -0.4983, p < 0.05) and PSQI scores (r = -0.5482, p < 0.05). The GABRB3 risk allele (rs764926719) correlated positively with EEI (r = 0.6161, p < 0.01) and FCQ scores (r = 0.6373, p < 0.01). The OPRM1 risk allele showed a positive correlation with the DERS score (r = 0.5228, p < 0.05). We also identified correlations between DERS and BMI change (r = 0.61; p < 0.01). Conclusions: These data support the potential benefit of a personalized medicinal approach inclusive of genetic testing and psychosocial trait questionnaires when counselling patients with obesity considering bariatric surgery. Future research will explore epigenetic factors that contribute to outcomes of bariatric surgery.

Abstract
Context Sleeve gastrectomy is an effective method for management of obesity. The Bariatric Analysis and Reporting Outcome System (BAROS) is a comprehensive and standard system for the assessment of outcomes of weight loss surgery. It is consisted of weight loss, changes in obesity-related comorbidities and quality of life measurements. We investigated results of the sleeve gastrectomy based on the BAROS. Material and Methods Outcomes of laparoscopic sleeve gastrectomy surgery was studied in 45 patients with obesity (11 male, 34 female), after 45 months in Turkey. Results Total weight loss was 26.4±0.1% of body weight at 45 months. Weight regain was seen in 97.8% of the patients with an average 14.5 kg and 13.7% body mass index points. The surgery caused 76% decrease in incidence of obstructive sleep apnea, 73% decrease in type 2 diabetes, 63% decrease in hyperlipidemia and 62% decrease in hypertension. Significant improvement is observed in all quality-of-life parameters. The final score of the BAROS was 4.23±1.02. Conclusion Based on BAROS, sleeve gastrectomy provides significant improvements in weight loss, incidence of medical comorbidities and quality of life after surgery. Future studies should address prevention of weight regain after the surgery.

Abstract
BACKGROUND Sleeve gastrectomy is one of the most popular bariatric surgeries. With the advent of new technologies, a reduced-port approach assisted by magnets for sleeve gastrectomy (RPSG-MA) has been developed. The aim of our study is to compare the short-term results of RPSG-MA vs conventional laparoscopic SG (CLSG). METHODS A comparative study was performed. We compared two groups who underwent RPSG-MA (n=150) and CLSG (n=135) between January 2020 and January 2022. RESULTS Both groups were similar in body mass index, age, sex, and type of comorbidities. The operative time was similar in both groups (RPSG-MA, 52.5 min vs CLSG, 52.9 min; p = 0.829). Length of hospital (1.07 days) stay was significantly shorter in the RPSG-MA group (p = 0.00) than in the CLSG group (1.51 days). There were no conversions to open surgery in any patient or any fatal event. Complications encountered were similar in both groups postoperative. There were minor adverse events directly related to the magnetic device in 3 cases, these being mild hepatic lacerations, resolved with hemostatic measures. CONCLUSION The magnet-assisted reduced-port gastric sleeve compared to the conventional technique has proven to be safe, technically feasible and with multiple benefits.

Abstract
INTRODUCTION Type 2 diabetes (T2DM) and obesity present significant global health issues, requiring the development of long-lasting and highly effective pharmacotherapies. Although glucagon-like peptide-1 receptor agonists (GLP-1RAs) are commonly used for diabetes treatment, their potential for addressing obesity is still being explored. AREAS COVERED This review offers a comprehensive overview of recently published patents from January 2020 to July 2023, focusing on modified GLP-1RAs, small molecule GLP-1RAs, GLP-1 R-based multi-agonists, GLP-1RA-based fusion proteins, and combination therapies. The patents discussed pertain to the treatment and prevention of diabetes and obesity. Patent searches were conducted using the PATENTSCOPE database of the World Intellectual Property Organization, using the keywords GLP-1, GLP-1/GIP, GLP-1/GCG, and GLP-1/GCG/GIP. EXPERT OPINION In recent years, patents have emphasized two main goals for developing GLP-1RAs drugs: oral delivery and improved weight reduction effects. To address the growing demand for improved treatments, researchers have focused their efforts on developing GLP-1 R-based multi-agonists, orally administered GLP-1RAs, and combination therapies utilizing GLP-1RAs. These new approaches offer promising benefits, such as improved effectiveness by targeting multiple pathways and reduced side effects. Additionally, the development of new uses, oral forms, and long-lasting preparations will be crucial in shaping the future market potential of GLP-1 drugs.

Abstract
Purpose The effect of hyperinsulinemia on short-term outcomes after laparoscopic sleeve gastrectomy (LSG) in patients with obesity combined with insulin resistance is unclear. Material and Methods This was a retrospective analysis of patients who underwent LSG at our center between January 1, 2020, and December 31, 2021. Patients were divided into hyperinsulinemia (HINS) and nonhyperinsulinemia (NHINS) groups based on fasting insulin levels. The primary endpoint was weight change. Metabolic disease outcomes, postoperative complications, and quality of life score changes were secondary endpoints. Results A total of 92 patients were included in this study, with 59 in the HINS group and 33 in the NHINS group. At 6 months postoperatively, the median (P25, P75) %EWL was 76.01 (64.40, 86.99)% in the HINS group and 92.02 (86.78, 100.88)% in the NHINS group (P<0.001). The mean %TWL (SD) was 23.26 (7.14)% in the HINS group and 26.80 (6.55)% in the NHINS group (P=0.021). The remission of dyslipidemia and hypertension in the NHINS group and the HINS group were not significantly different (P>0.05 for all). The differences in QOL between groups were not statistically significant (P=0.788). In terms of postoperative complications, there was no statistically significant difference between the groups (P>0.05 for all). Conclusion HINS negatively influences weight change in patients with obesity and insulin resistance, and the NHINS group had better postoperative weight loss. In terms of hypertension, dyslipidemia, and postoperative complications, there was no significant effect of HINS.

ANNALS OF SURGERY OPEN 2023; 4:e286. [PMID: 37601481 PMCID: PMC10431536 DOI: 10.1097/as9.0000000000000286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 04/13/2023] [Indexed: 08/22/2023] Open
Abstract
Objective The study aimed to assess major adverse cardiovascular events (MACEs), complications requiring revision surgery, and bariatric conversion surgery 7 years after gastric bypass (GB) and sleeve gastrectomy (SG) using real-world data. Background GB and SG both result in weight loss and improved cardiometabolic health. Whether the long-term rate of MACE differs between the 2 bariatric procedures is unclear. Methods In this population-based retrospective cohort study, we used inhospital National Health Registry data from January 2012 to December 2018. Patients undergoing GB were 1:1 propensity score-matched with patients who had SG. The primary outcome was the incidence of MACE, defined as acute myocardial infarction, ischemic stroke, cardiac arrest, or hospitalization for heart failure. Secondary outcomes encompassed individual MACE components, postoperative complications, and the need for bariatric conversion surgery. Results Among 5240 propensity score-matched pairs, the incidence rate per 1000 person-years of MACE was 2.8 among patients undergoing GB and 3.2 among those undergoing SG (hazard ratio [HR], 0.92; 95% confidence interval [CI], 0.62-1.37). Single components of MACE were not different between both groups. Patients after GB had a higher risk of long-term postoperative complications requiring a revision surgery compared with those after SG (HR, 3.53 [95% CI, 2.78-4.49]). Bariatric conversion surgery was less frequently performed among patients undergoing GB compared with patients undergoing SG (HR, 0.09 [95% CI, 0.06-0.13]). Conclusions In this study, the performance of GB versus SG was associated with a similar risk of MACE. While postoperative complications were more frequent among patients undergoing GB, patients following SG had a higher probability of bariatric conversion surgery.

Abstract
Diabetes mellitus is one of the major epidemics in the United States. It is heavily associated with obesity and multiple metabolic derangements that lead to long term morbidity, mortality as well as financial burden. Although medical therapy has been the mainstay in the management of diabetes mellitus, there remains a large portion of this patient population which struggles to obtain adequate glycemic control and long-term weight control with medical management alone. Bariatric surgery is a powerful tool in combating diabetes mellitus and affects glucose homeostasis through a variety of pathways. While it does provide a durable pathway for weight loss, improvement in glucose homeostasis is not only affected by the weight loss seen after bariatric surgery. Changes in gut hormone secretion, insulin regulation, and gut microbial composition also affect how these operations improve glucose homeostasis. Through improvement in the management of diabetes mellitus, comorbidities including cardiovascular disease, in turn demonstrate improvement. In this article, we will discuss the role of bariatric (metabolic) surgery as it relates to long term weight loss and the impact that weight loss has on improvement in diabetes mellitus.

Abstract
This is a systematic review and meta-analysis that assessed the impact of performing OAGB with a 150-cm BPL versus a 200-cm BPL concerning weight loss, comorbidities remission, and adverse nutritional effects. The analysis included studies that compared patients who underwent OAGB with a 150-cm BPL and 200-cm BPL. Eight studies were eligible for this review after searching in the EMBASE, PubMed central database, and Google scholar. The pooled analysis revealed favoring the 200-cm BPL limb length for weight loss, with a highly significant difference in the TWL% (p=0.009). Both groups showed comparable comorbidities remission. Significantly higher ferritin and folate deficiency rates were found in the 200-cm BPL group. Considering a 200-cm BPL when performing OAGB delivers a better weight loss outcome than a 150-cm BPL, which is at the expense of a more severe nutritional deficiency. No significant differences were found regarding the comorbidities' remission.

Int J Obes (Lond) 2023:10.1038/s41366-023-01298-1. [PMID: 37005473 DOI: 10.1038/s41366-023-01298-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 03/08/2023] [Accepted: 03/14/2023] [Indexed: 04/04/2023]
Abstract
BACKGROUND Randomized controlled trials (RCTs) are regarded as high-level evidence, but the strength of their P values can be difficult to ascertain. The Fragility Index (FI) is a novel metric that evaluates the frailty of trial findings. It is defined as the minimum number of patients required to change from a non-event to event for the findings to lose statistical significance. This study aims to characterize the robustness of bariatric surgery RCTs by examining their FIs. METHODS A search was conducted in MEDLINE, EMBASE, and CENTRAL from January 2000 to February 2022 for RCTs comparing two bariatric surgeries with statistically significant dichotomous outcomes. Bivariate correlation was conducted to identify associations between FI and trial characteristics. RESULTS A total of 35 RCTs were included with a median sample size of 80 patients (Interquartile range [IQR] 58-109). The median FI was 2 (IQR 0-5), indicating that altering the status of two patients in one treatment arm would overturn the statistical significance of results. Subgroup analyses of RCTs evaluating diabetes-related outcomes produced a FI of 4 (IQR 2-6.5), while RCTs comparing Roux-en-Y gastric bypass and sleeve gastrectomy had an FI of 2 (IQR 0.5-5). Increasing FI was found to be correlated with decreasing P value, increasing sample size, increasing number of events, and increasing journal impact factor. CONCLUSION Bariatric surgery RCTs are fragile, with only a few patients required to change from non-events to events to reverse the statistical significance of most trials. Future research should examine the use of FI in trial design.

INTRODUCTION Definitions and prevalence of weight regain (WR) after bariatric surgery remains inconsistent and their clinical significance unclear. OBJECTIVES To assess WR five years after sleeve gastrectomy (LSG), employing six definitions; and appraise their association with patient characteristics/clinical outcomes. METHODS Consecutive patients (N = 589) who underwent LSG were followed up for 5 years. WR prevalence was calculated yearly employing six definitions. Regression analysis assessed associations between WR at 5 years, and patient characteristics (age, sex, preop BMI, number of follow-up visits, number of comorbidities) and remission of comorbidities (type 2 diabetes, hypertension, and dyslipidemia). RESULTS Sample's mean age and BMI were 34 ± 11.6 years and 43.13 ± 5.77 kg/m2, and 64% were females. Percentage of patients with WR at 2, 3, 4, and 5 years fluctuated between 2.53% and 94.18%, subject to definition, and time point. The definition "Any WR" generated the highest prevalence of WR (86-94%) across all time points. At 5 years, for patient characteristics, preoperative BMI was associated with three definitions (P 0.49 to < 0.001), sex was associated with two (P < 0.026-0.032), and number of comorbidities was associated with one definition (P = 0.01). In terms of comorbidities, only hypertension was associated with WR (one definition, P = 0.025). No other definitions of WR were associated with any of the variables under examination. CONCLUSION Weight regain is reasonably expected after BMS. WR definitions were of minor clinical significance due to weak associations with limited comorbidities. Dichotomous definitions might offer some guidance while managing individual patients. However, its utility as a comparator metric across patients/procedures requires refinements.

Long-term weight loss outcome of laparoscopic Roux-en-Y gastric bypass predicted by weight loss at 6 months in Chinese patients with BMI ≥ 32.5 kg/m2. Medicine (Baltimore) 2023; 102:e33235. [PMID: 36961197 PMCID: PMC10036043 DOI: 10.1097/md.0000000000033235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Accepted: 02/17/2023] [Indexed: 03/25/2023] Open
Abstract
Laparoscopic Roux-en-Y gastric bypass (LRYGB) is classic bariatric procedure with long-term safety and efficacy. However, no studies have focused on predicting long-term weight loss after LRYGB in Chinese patients with body mass index (BMI) ≥ 32.5 kg/m2. To explore the relationship between initial and long-term weight loss after LRYGB in patients with BMI ≥ 32.5 kg/m2. All patients were followed-up to evaluate BMI, percentage of excess weight loss (%EWL), and comorbidities. Linear and logistic regression were performed to assess the relationship between initial and long-term weight loss. Receiver operating characteristic curve was used to determine optimal cutoff value. We enrolled 104 patients. The median preoperative BMI was 41.44 (37.92-47.53) kg/m2. %EWL ≥ 50% at 5 years was considered as successful weight loss, and 75.00% of the patients successfully lost weight. The cure rates of hypertension, hyperlipidemia, and type 2 diabetes mellitus at 1 year were 84.38%, 33.93%, and 60.82%, respectively. %EWL at 6 months and 5 years were positively correlated and its relationship could be described by following linear equation: %EWL5 years = 43.934 + 0.356 × %EWL6 months (P < .001; r2 = 0.166). The best cutoff %EWL at 6 months after LRYGB to predict 5-year successful weight loss was 63.93% (sensitivity, 53.85%; specificity, 84.62%; area under the curve (AUC) = 0.671). In Chinese patients with BMI ≥ 32.5 kg/m2, %EWL at 6 months and 5 years were positively correlated and %EWL at 5 years could be calculated by following linear equation: %EWL5 years = 43.934 + 0.356 × %EWL6 months.

Conversion of Sleeve Gastrectomy to Roux-en-Y Gastric Bypass: Indications, Prevalence, and Safety. Obes Surg 2023; 33:1486-1493. [PMID: 36922465 PMCID: PMC10017068 DOI: 10.1007/s11695-023-06546-x] [Citation(s) in RCA: 19] [Impact Index Per Article: 19.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 02/28/2023] [Accepted: 03/07/2023] [Indexed: 03/17/2023]
Abstract
BACKGROUND Sleeve gastrectomy (SG) frequently requires conversion to Roux-en-Y gastric bypass (RYGB) due to gastroesophageal reflux disease (GERD) or weight recurrence. Current evidence evaluating the safety of conversion from SG to RYGB and its indications is limited to single centers. METHODS The objective was to determine the rate of serious complications and mortality of conversion of SG to RYGB (SG-RYGB) compared to primary RYGB (P-RYGB). This was a retrospective analysis of the MBSAQIP database which includes 30-day outcomes. Individuals undergoing P-RYGB or SG-RYGB were included. Multivariable logistic regression was performed to determine if revisional surgery was an independent predictor of serious complications or mortality. RESULTS In 2020 and 2021, 84,543 (86.3%) patients underwent P-RYGB and 13,432 (13.7%) underwent SG-RYGB. SG-RYGB cohort had lower body mass index, lower rates of diabetes and hypertension, and higher rates of GERD. GERD was the most common indication for revision (55.3%) followed by weight regain (24.4%) and inadequate weight loss (12.7%). SG-RYGB had longer operative times (145 vs. 125 min, p < 0.001) and a higher rate of serious complications (7.2 vs. 5.0%, p < 0.001). This included higher rates of anastomotic leak (0.5 vs. 0.4%, p = 0.002), bleeding (2.0 vs. 1.6%, p < 0.001), and reoperation (3.0 vs. 1.9%, p < 0.001) but not death (0.1 vs. 0.1%, p = 0.385). On multivariable analysis, SG-RYGB was independently predictive of serious complications (OR 1.21, 95%CI 1.12 to 1.32, p < 0.001) but not mortality (p = 0.316). CONCLUSIONS While SG-RYGB is safe with a low complication rate, SG-RYGB was associated with a higher rate of serious complications compared to P-RYGB.

Laparoscopic Sleeve Gastrectomy versus Laparoscopic Roux-en-Y Gastric Bypass: An Analysis of Weight Loss Using a Multilevel Mixed-Effects Linear Model. J Clin Med 2023; 12:jcm12062132. [PMID: 36983135 PMCID: PMC10051768 DOI: 10.3390/jcm12062132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 02/27/2023] [Accepted: 03/06/2023] [Indexed: 03/11/2023] Open
Abstract
Background: Regarding weight loss outcomes, the results published after laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y (LRYGB) are conflicting. At this time, no clear evidence exists that outcomes from LSG are similar to those for LRYGB. The main objective of this study was to compare the percent of total weight loss (%TWL) between LRYGB and LSG over the first 2 years using a multilevel mixed-effects linear regression. Methods: Data were collected from a prospectively maintained database of patients who underwent primary laparoscopic bariatric surgery from January 2016 to December 2017 at a French accredited bariatric center. The medical records of 435 consecutive patients were analyzed. %TWL was calculated at each follow-up surgical consultation and used as a repeated outcome variable in our models to assess the long-term %TWL. Due to this hierarchical structure of the data (%TWL at each visit = level 1) within patients (level 2), a multilevel linear regression adjusted for age, sex, preoperative BMI and comorbidities was used. Results: Among the medical records of 435 consecutive patients included, 266 patients underwent LRYGB and 169 underwent LSG. The average %TWL at 2 years was 31.7% for the LRYGB group and 25.8% for the LSG group. The final multivariate model showed that, compared with LRYGB, LSG was associated with a decreased %TWL at over 2 years of follow-up (β: −4.01; CI95%: −5.47 à −2.54; p ≤ 0.001). Conclusion: This observational study suggests that compared with LRYGB, LSG was associated with a decreased %TWL at 2 years using a multilevel model. Further studies are required to confirm the results observed with this statistical model.

Abstract
Bariatric surgery (BS) is escalating as the most efficient and endurable therapy for severe obesity. Women's reproductive health is essential to women's quality of life and is receiving increasing attention. However, despite the high prevalence of BS among women, the effect of BS on reproductive health remains underemphasis. The purpose of this narrative review is to provide an overview of BS on women's reproductive health, including their reproductive health before, during, and after pregnancy. Although limited attention has been given, current evidence highlights the substantial implications of bariatric surgery on reproductive health and reminds us of the importance of adopting decision-making conversations about reproductive health before bariatric surgery.

Parental Obesity Predisposition and Age of Onset Associate with Poor Response to Bariatric and Metabolic Surgery. Obes Surg 2023; 33:1519-1527. [PMID: 36856989 PMCID: PMC10156869 DOI: 10.1007/s11695-023-06499-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 01/27/2023] [Accepted: 02/07/2023] [Indexed: 03/02/2023]
Abstract
INTRODUCTION Parental predisposition and age of onset may be independently associated with 1-year total weight loss (TWL) failure (< 20%) after metabolic-bariatric surgery (MBS). METHODS This cohort study includes all cases of the German StuDoQ|MBE register (2015-2019) with data on parental predisposition, obesity onset, and at least 1-year follow up after primary MBS procedures (n = 14,404). We provide descriptive statistics of the cohort in terms of the main outcome and 1-year TWL failure, and provide characteristics of surgery type subgroups. Finally, we provide a multivariate logistic regression model of 1-year TWL failure. RESULTS 58.8% and 45.7% of patients reported maternal and paternal predisposition for obesity, respectively. Average onset of obesity was 15.5 years and duration of disease 28.3 years prior to MBS. SG is the most frequently performed procedure (47.2%) followed by RYGB (39.7%) and OAGB (13.1%). Mean 1-year TWL is 32.7 ± 9.3%, and 7.8% (n = 1,119) of patients show TWL failure (< 20%). Multivariate analysis shows independent association of early onset of obesity (< 18 years), male sex, age at operation, pre-operative BMI, pre-operative weight loss, sleeve gastrectomy (SG), and type 2 diabetes (T2D) with 1-year TWL failure (p < 0.001). CONCLUSION The proportions of MBS patients that report on paternal and maternal predisposition for obesity are 45.7% and 58.8% respectively, and average age at onset is 15.5 years. 7.8% of patients do not meet current target criteria of successful response to surgery at 1 year. Early onset, male sex, age at operation, pre-operative BMI, pre-operative weight loss, SG, and T2D are independently associated with weight loss failure.

Abstract
BACKGROUND To demonstrate the association of irisin levels with impaired glucose before and after laparoscopic sleeve gastrectomy (LSG) in patients with obesity. METHODS Thirty-six patients with obesity undergoing LSG were included. We tested the irisin levels before and after LSG and conducted an evaluation of baseline irisin levels with elevated glucose as well as irisin changes with weight loss and its association with glucose control after LSG. RESULTS Anthropometric measurements, body fat index, and metabolic parameters were significantly improved in 3 months following LSG (all p < 0.05). Baseline irisin levels were significantly higher in obesity with elevated fasting glucose than that with normal glucose (2.98 [2.37, 3.63] vs. 3.72 [3.06, 5.32], p = 0.031). After adjustment for sex, gender, and body mass index (BMI), obesity with higher irisin levels was prone to have impaired fasting glucose (OR = 2.499, 95% CI = 1.047-5.964). According to receiver operating characteristic curve analysis, the diagnostic accuracy and sensitivity of baseline irisin levels on impaired fasting glucose were 75% and 77.8%. Irisin levels decreased from 3.29 (2.67, 4.43) to 2.82 (2.41, 3.25) ng/mL (p = 0.009) after LSG. The decreases of weight, BMI, and FFA were more in irisin changes group (△irisin ≥ 0.5) than in no irisin changes group (△irisin < 0.5). And △irisin was negatively associated with postprandial glucose (PG) at 3 months after LSG (0.5 h-PG, r = - 0.478, p = 0.029; 2 h-PG, r = - 0.406, p = 0.017). CONCLUSIONS Elevated baseline irisin levels indicated the impaired glucose in obesity. The decrease of irisin with weight loss provided more evidence for the contribution of serum irisin secretion by fat mass in obesity.

Abstract
BACKGROUND Bariatric surgery can improve renal function in patients with comorbid chronic kidney disease (CKD) and obesity. Additionally, bariatric surgery can enhance outcomes following renal transplantation. The safety of bariatric surgery in patients with CKD has been debated in the literature. This study evaluates the frequency of perioperative complications associated with CKD. METHODS The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was queried from 2015-2019. Patients were included if they had a vertical sleeve gastrectomy (VSG) or Roux-en-Y gastric bypass (RYGB) and were stratified based on CKD status. An unmatched and propensity-matched analysis was performed comparing 30-day perioperative outcomes between the groups. RESULTS A total of 717,809 patients included in this study, 5817(0.8%) had CKD, of whom 2266(0.3%) were on dialysis. 74.3% of patients with CKD underwent VSG with 25.7% underwent RYGB. Comparing RYGB to VSG, patients who underwent RYGB had a higher rate of deep organ space infection (0.7%vs.0.1%,p = 0.021) and re-intervention (5.0% vs. 2.2%,p < 0.001). Within the VSG cohort, a matched analysis was performed for those with CKD and without CKD. The CKD cohort had higher risk of complications such as bleeding (2.1%vs. 0.9%,p < 0.001), readmission (9.3%vs.4.9%,p < 0.001), reoperation (2.7%vs.1.3%,p < 0.001), and need for reintervention (2.2%vs.1.3%,p < 0.001). Notably, patients with CKD also had a higher mortality (0.6%vs.0.2%,p = 0.003). No difference was seen between patients with renal insufficiency and patients on dialysis. CONCLUSION VSG has been the operation of choice in patients with CKD. Our results showed it is the safer option for patients with CKD compared to RYGB. Although this patient population does have an increased risk of adverse perioperative events, dialysis didn't affect the outcome. Bariatric surgeons who operate on patients with CKD should be well informed and remain vigilant given the increased perioperative risk. The risk is still considerably low, and the potential benefit on renal function and improvement in candidacy for renal transplant outweigh the risk. They should be considered as surgical candidates.

Abstract
BACKGROUND Previously, we reported short-term improvements in auditory attention, oromotor processing speed, and executive function during the active weight loss phase following bariatric surgery that persisted out to 3 months. In this study, our aims were to investigate the relationship between weight loss and cognitive performance in these patients 1 year following vertical sleeve gastrectomy (VSG) and Roux-en Y gastric bypass (RYGB) surgery and to determine whether preoperative cognitive performance predicted weight loss. METHODS Adult women ages 18-55 approved for bariatric surgery completed a cognitive battery prior to and at 2, 12, 24, and 52 weeks following VSG (N = 17) or RYGB (N = 18). Scores from each task were assigned to one of the following cognitive domains: auditory attention, processing speed, memory, and executive functioning. Weight loss and cognitive scores for each domain were calculated and compared between cohorts. RESULTS RYGB surgery resulted in greater weight loss at 1-year follow-up relative to VSG. Both VSG and RYGB procedures resulted in improved performance on different measures of auditory attention and both surgery groups improved across all processing speed tasks. Within the executive function domain, both groups showed improvements, but only the RYGB procedure resulted in improved performance in the Trail Making Test. Baseline auditory attention and memory performance predicted weight loss at 1 year following RYGB but not VSG surgery. Controlling for baseline cognitive performance, percent total weight loss predicted auditory attention at 1 year following RYGB but not VSG surgery. CONCLUSIONS Bariatric surgery type may result in selective improvements in cognition during the first year following surgery. Presurgical cognitive performance as well as surgery type appears to influence weight loss outcomes.

Abstract
BACKGROUND Literature remains scarce on patients experiencing weight recurrence after initial adequate weight loss following primary bariatric surgery. Therefore, this study compared the extent of weight recurrence between patients who received a Sleeve Gastrectomy (SG) versus Roux-en-Y gastric bypass (RYGB) after adequate weight loss at 1-year follow-up. METHODS All patients undergoing primary RYGB or SG between 2015 and 2018 were selected from the Dutch Audit for Treatment of Obesity. Inclusion criteria were achieving ≥ 20% total weight loss (TWL) at 1-year and having at least one subsequent follow-up visit. The primary outcome was ≥ 10% weight recurrence (WR) at the last recorded follow-up between 2 and 5 years, after ≥ 20% TWL at 1-year follow-up. Secondary outcomes included remission of comorbidities at last recorded follow-up. A propensity score matched logistic regression analysis was used to estimate the difference between RYGB and SG. RESULTS A total of 19.762 patients were included, 14.982 RYGB and 4.780 SG patients. After matching 4.693 patients from each group, patients undergoing SG had a higher likelihood on WR up to 5-year follow-up compared with RYGB [OR 2.07, 95% CI (1.89-2.27), p < 0.01] and less often remission of type 2 diabetes [OR 0.69, 95% CI (0.56-0.86), p < 0.01], hypertension (HTN) [OR 0.75, 95% CI (0.65-0.87), p < 0.01], dyslipidemia [OR 0.44, 95% CI (0.36-0.54), p < 0.01], gastroesophageal reflux [OR 0.25 95% CI (0.18-0.34), p < 0.01], and obstructive sleep apnea syndrome (OSAS) [OR 0.66, 95% CI (0.54-0.8), p < 0.01]. In subgroup analyses, patients who experienced WR after SG but maintained ≥ 20%TWL from starting weight, more often achieved HTN (44.7% vs 29.4%), dyslipidemia (38.3% vs 19.3%), and OSAS (54% vs 20.3%) remission compared with patients not maintaining ≥ 20%TWL. No such differences in comorbidity remission were found within RYGB patients. CONCLUSION Patients undergoing SG are more likely to experience weight recurrence, and less likely to achieve comorbidity remission than patients undergoing RYGB.

Comparison of early post-operative complications in primary and revisional laparoscopic sleeve gastrectomy, gastric bypass, and duodenal switch MBSAQIP-reported cases from 2015 to 2019. Surg Endosc 2023; 37:3728-3738. [PMID: 36653536 DOI: 10.1007/s00464-022-09796-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Accepted: 11/27/2022] [Indexed: 01/20/2023]
Abstract
BACKGROUND Sleeve gastrectomy (SG) is now the most performed bariatric surgery, though gastric bypass (GB) and duodenal switch (DS) remain common, especially as conversion/revision (C/R) procedures. This analysis compared early postoperative outcomes of primary and C/R laparoscopic SG to DS and GB; and primary procedures of each vs C/R counterparts. METHODS The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) dataset was queried for SG, GB, and DS cases from 2015 to 2019. Multivariable logistic regression calculated crude and adjusted odds ratios for surgical site infection (SSI), reoperation, and readmission at 30 days in two initial comparisons: (1) primary SG vs DS or GB and (2) C/R SG vs DS or GB. A secondary analysis compared primary GS, GB, or DS with C/R counterparts. Models were adjusted for confounding demographics and comorbidities. RESULTS Of 755,968 primary cases, most were SG (72.8%), followed by GB (26.3%), then DS (0.9%). Compared to SG, GB and DS demonstrated higher odds of SSI (aOR 3.02 [2.84, 3.2]), readmission (aOR 1.97 [1.92, 2.03]), and reoperation (aOR 2.74 [2.62, 2.86]), respectively. Of 68,716 C/R cases, SG was most common (43.2%), followed by GB (37.5%), then DS (19.2%). C/R GB and DS demonstrated greater risk of SSI (aOR 2.28 [1.98, 2.62]), readmission (aOR 2.10 [1.94, 2.27]), and reoperation (aOR 2.3 [2.04, 2.59]) vs SG, respectively. C/R SG and DS demonstrated greater risk of SSI (OR 2.09 [1.66, 2.63]; 1.63 [1.24, 2.14), readmission (OR 1.13 [1.02, 1.26]), and reoperation (OR 1.27 [1.06, 1.52]; 1.58 [1.24, 2.0]), vs primary procedures. C/R DS demonstrated greater risk of SSI (OR 1.23 [1.66, 2.63]). CONCLUSIONS Early complications are comparable between GB and DS, and greater than SG. In C/R procedures, GB and DS demonstrate greater risk than SG. Overall, C/R procedures demonstrate greater risk of most, but not all, early postoperative complications.

Intestinal Calcium Absorption Decreases After Laparoscopic Sleeve Gastrectomy Despite Optimization of Vitamin D Status. J Clin Endocrinol Metab 2023; 108:351-360. [PMID: 36196648 PMCID: PMC10091486 DOI: 10.1210/clinem/dgac579] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 08/30/2022] [Indexed: 01/20/2023]
Abstract
CONTEXT Laparoscopic sleeve gastrectomy (LSG), now the most commonly performed bariatric operation, is a highly effective treatment for obesity. While Roux-en-Y gastric bypass is known to impair intestinal fractional calcium absorption (FCA) and negatively affect bone metabolism, LSG's effects on calcium homeostasis and bone health have not been well characterized. OBJECTIVE We determined the effect of LSG on FCA, while maintaining robust 25-hydroxyvitamin D (25OHD) levels and recommended calcium intake. DESIGN, SETTING, PARTICIPANTS Prospective pre-post observational cohort study of 35 women and men with severe obesity undergoing LSG. MAIN OUTCOMES FCA was measured preoperatively and 6 months postoperatively with a gold-standard dual stable isotope method. Other measures included calciotropic hormones, bone turnover markers, and bone mineral density (BMD) by dual-energy X-ray absorptiometry and quantitative computed tomography. RESULTS Mean ± SD FCA decreased from 31.4 ± 15.4% preoperatively to 16.1 ± 12.3% postoperatively (P < 0.01), while median (interquartile range) 25OHD levels were 39 (32-46) ng/mL and 36 (30-46) ng/mL, respectively. Concurrently, median 1,25-dihydroxyvitamin D level increased from 60 (50-82) pg/mL to 86 (72-107) pg/mL (P < 0.01), without significant changes in parathyroid hormone or 24-hour urinary calcium levels. Bone turnover marker levels increased substantially, and areal BMD decreased at the proximal femur. Those with lower postoperative FCA had greater areal BMD loss at the total hip (ρ = 0.45, P < 0.01). CONCLUSIONS FCA decreases after LSG, with a concurrent rise in bone turnover marker levels and decline in BMD, despite robust 25OHD levels and with recommended calcium intake. Decline in FCA could contribute to negative skeletal effects following LSG.

Abstract
INTRODUCTION It could be valuable for surgeons and patients to use one chart in different groups and evaluate weight loss during the post-surgery period. METHODS This retrospective study used the Iran National Obesity Surgery Database. Patients with clinically severe obesity aged 18-70 undergoing sleeve gastrectomy participated in this study. Body mass index (BMI) reduction and 5 other metrics measured over the study period were modeled using lambda-mu-sigma method. Our data were split into the train (70%) and test (30%) sets. RESULTS In this study, 1,258 patients (75% female) met the eligibility criteria to participate. Mean age and initial BMI were 36.87 ± 10.51 and 42.74 (40.37-46.36), respectively. Percentile charts for various metrics have been presented for the first 2 years after surgery. CONCLUSIONS For sleeve surgery, all metrics are acceptable for clinical applications. Using the statistical view, BMI reduction is the most acceptable metric according to the lowest bias values and its variation between all the metrics.

Abstract
BACKGROUND Long-term laparoscopic sleeve gastrectomy (LSG) outcomes in patients with obesity are scarce. We aimed to examine the outcomes and subjective experience of patients who underwent primary LSG with long-term follow-up. METHODS The study is a retrospective observational analysis of patients who underwent primary LSG in a single center with 5-15 years of follow-up. Patients' hospital chart data supplemented by a detailed follow-up online questionnaire and telephone interview were evaluated. RESULTS The study sample included 578 patients (67.0% female) with 8.8 ± 2.5 years of mean follow-up, with a response rate to the survey of 82.8%. Mean baseline age and body mass index (BMI) were 41.9 ± 10.6 years and 42.5 ± 5.5 kg/m2, respectively. BMI at nadir was 27.5 ± 4.9 kg/m2, corresponding to a mean excess weight loss (EWL) of 86.9 ± 22.8%. Proportion of patients with weight regain, defined as nadir ≥ 50.0% EWL, but at follow-up < 50.0% EWL, was 34.6% (n = 200) and the mean weight regain from nadir was 13.3 ± 11.1 kg. BMI and EWL at follow-up were 32.6 ± 6.4 kg/m2 and 58.9 ± 30.1%, respectively. The main reasons for weight regain given by patients included "not following guidelines," "lack of exercise," "subjective impression of being able to ingest larger quantities of food in a meal," and "not meeting with the dietitian." Resolution of obesity-related conditions at follow-up was reported for hypertension (51.7%), dyslipidemia (58.1%) and type 2 diabetes (72.2%). The majority of patients (62.3%) reported satisfaction with LSG. CONCLUSIONS In the long term, primary LSG was associated with satisfactory weight and health outcomes. However, weight regain was notable.

Abstract
It has been proven that surgery is more effective than non-surgical treatment in obese patients. However, this approach has several disadvantages, especially long-term weight loss. Weight loss failures can be broadly classified into two categories; insufficient weight loss (poor responder) and weight regain. However, a unified definition has not been established yet for each category, and there is no clear standard for the post-surgery time point to be used to assess weight loss failure. In addition, analyzing factors that contribute to weight loss failure will lead to strategies for reducing it. Therefore, many researchers have been interested in this subject and have published conflicting results. This review presents a definition for and describes the mechanisms and predictors of weight loss failure after bariatric surgery.

Abstract
Obesity is a growing problem worldwide. For the first time since 2010, more people have been overweight than underweight. In particular, obesity-associated diseases, above all type 2 diabetes mellitus, pose enormous challenges to the healthcare system. On July 3, 2020, the German Bundestag recognised obesity as a disease and initiated the development of a diseases management program (DMP), which is currently being drawn up. So far, the indication for treatment of obesity in Germany has been based on the S3 guideline "Surgery of obesity and metabolic diseases" of the DGAV from 2018 and the S3 guideline "Prevention and therapy of obesity" of the German Obesity Society e. V. from 2014. This article gives an overview of the currently available conservative, medical, endoscopic and surgical treatment methods for overweight and obesity in Germany and explains the indications. Against the background of the reorientation of obesity treatment as a part of the DMP and the forthcoming revisions of the guidelines, the previous indication should be discussed critically. The scientific findings of the last few years show that surgical treatment of obesity not only achieves the greatest weight loss in the long term, but also that obesity-associated diseases are then treated more effectively and overall mortality is reduced significantly more effectively than with conservative treatment.

Abstract
IMPORTANCE Severe obesity is a major health concern. However, a few patients remain resistant to bariatric surgery and other treatments. Animal studies suggest that weight may be altered by fecal microbiota transplantation (FMT) from a lean donor. OBJECTIVE To determine whether FMT from a lean donor reduces body weight and further improves the results of bariatric surgery. DESIGN, SETTING, AND PARTICIPANTS This double-blinded, placebo-controlled, multicenter, randomized clinical trial was conducted in 2018 to 2021 among adult individuals with severe obesity treated at 2 bariatric surgery centers in Finland and included 18 months of follow-up. Patients eligible for bariatric surgery were recruited for the study. Data were analyzed from March 2021 to May 2022. INTERVENTIONS FMT from a lean donor or from the patient (autologous placebo) was administered by gastroscopy into the duodenum. Bariatric surgery was performed 6 months after the baseline intervention using laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG). MAIN OUTCOMES AND MEASURES The main outcome was weight reduction measured as the percentage of total weight loss (TWL). RESULTS Forty-one patients were recruited to participate in the study and were included in the final analysis (29 women [71.1%]; mean [SD] age, 48.7 [8.7] years; mean [SD] body mass index, 42.5 [6.0]). A total of 21 patients received FMT from a lean donor, and 20 received an autologous placebo. Six months after FMT, 34 patients underwent LRYGB and 4 underwent LSG. Thirty-four patients (82.9%) attended the last visit 18 months after the baseline visit. The percentage of TWL at 6 months was 4.8% (95% CI, 2.7% to 7.0%; P < .001) in the FMT group and 4.6% (95% CI, 1.5% to 7.6%; P = .006) in the placebo group, but no difference was observed between the groups. At 18 months from the baseline (ie, 12 months after surgery), the percentage of TWL was 25.3% (95% CI, 19.5 to 31.1; P < .001) in the FMT group and 25.2% (95% CI, 20.2 to 30.3; P < .001) in the placebo group; however, no difference was observed between the groups. CONCLUSIONS AND RELEVANCE FMT did not affect presurgical and postsurgical weight loss. Further studies are needed to elucidate the possible role of FMT in obesity.

Abstract
BACKGROUND Loss-of-control (LOC)-eating postoperatively predicts suboptimal longer-term outcomes following bariatric surgery. This study examined longer-term effects through 24-month follow-ups after completing treatments in a randomized controlled trial testing guided-self-help treatments (cognitive-behavioral therapy [gshCBT] and behavioral weight-loss [gshBWL]) and control (CON) delivered postoperatively for LOC-eating. METHODS 140 patients with LOC-eating 6 months after bariatric surgery were randomized (5:5:2 ratio) to 3-months of gshCBT (n = 56), gshBWL (n = 60), or CON (n = 24) delivered by trained allied-health clinicians. Independent assessments were performed throughout/after treatments and at 6-, 12-, 18-, and 24-month follow-ups; 83% of patients were assessed at 24-month follow-up. RESULTS Intention-to-treat analyses comparing the three groups (gshCBT vs. gshBWL vs. CON) in LOC-eating abstinence at posttreatment (30%, 27%, 38%), 12-month follow-up (34%, 32%, 42%), and 24-month follow-up (45%, 32%, 38%) revealed no significant differences. Mixed-models revealed significantly reduced LOC-eating frequency through posttreatment, no significant changes in LOC-eating frequency during follow-up, and no differences between the three groups. Weight reduced significantly, albeit modestly, through posttreatment but increased significantly and substantially during follow-ups, with no differences between groups. CONCLUSIONS Overall, the 12-week scalable guided-self-help treatments did not differ from each other or control, were associated with significantly reduced frequency of LOC-eating and modest weight loss at posttreatment but were followed by significant weight gain during the 24-month follow-up. Weight gain was substantial and nearly universal whereas the frequency of LOC-eating did not change over time (i.e., LOC-eating reductions and abstinence rates were well maintained through 24-moth follow-ups). Patients with postoperative LOC-eating require more intensive adjunctive treatments. PUBLIC SIGNIFICANCE Loss-of-control (LOC) eating postoperatively predicts poorer bariatric surgery outcomes and the longer-term effects of postoperative adjunctive postoperative interventions for LOC eating are unknown. In this 24-month follow-up of a controlled study of scalable guided-self-help treatments and a control condition, improvements in LOC-eating frequency, eating-disorder psychopathology, and depression during treatment were maintained well, with no differences between the three groups. Proportion of patients achieving abstinence from LOC-eating at the 24-month follow-up ranged from 38% to 45% across the three groups. In contrast, weight increased significantly during the 24-month follow-ups, with no differences between the three groups. Findings suggest LOC-eating following bariatric surgery might represent a "marker" for a subgroup of patients that are at risk for substantial weight gains over time. LOC eating following bariatric surgery is challenging to treat with low-intensity scalable treatments and may require more intensive specialist treatments.

Effects of Antibiotics on Weight in Obese Patients after Sleeve Gastrectomy. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:1592786. [PMID: 36193079 PMCID: PMC9526625 DOI: 10.1155/2022/1592786] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 08/29/2022] [Accepted: 09/08/2022] [Indexed: 11/17/2022]
Abstract
Obese patients can significantly reduce weight and have a positive impact on obesity-related diseases. However, the risk of infection complications in obese people is higher than that in normal people, especially the surgical site infection. This research investigates the effect of antibiotics on weight change of obese patients after laparoscopic sleeve gastrectomy (LSG). A retrospective analysis was performed on 131 morbidly obese patients or obese patients with complications who received LSG treatment in the Third Hospital of Shanxi Medical University from 2013 to 2020. Patients were separated into the antibiotic group (59 cases) and the normal group (72 cases) according to whether antibiotics were used after surgery. The differences of postoperative weight-related indexes, inflammation-related indexes, and short-term complications were compared between the two groups. At 12-month follow-up, the % excess weight loss (%EWL) in the antibiotic group was statistically abated than that in the normal group (92.99 ± 28.60, P < 0.01). In addition, the percentage of total weight loss (%total weight loss (%TWL)) was abated in the antibiotic group than in the normal group, but it was not significant (P > 0.05). White blood cell count and neutrophil count in the antibiotic group were statistically raised than those in the in normal group (P < 0.05), but neutrophil/lymphocyte ratio (NLR) showed no significant difference. Comparison of short-term postoperative complications between the two groups showed that the number of abdominal wall wound infection, body temperature > 38°C, and abdominal pain > 3 days in the antibiotic group were abated, but they were not statistically significant (P > 0.05). Short-term antibiotic exposure after sleeve gastrectomy had an adverse effect on postoperative weight loss, with no significant improvement in short-term complications.

Abstract
IMPORTANCE The comparative effectiveness of the most common operations in the long-term management of dyslipidemia is not clear. OBJECTIVE To compare 4-year outcomes associated with vertical sleeve gastrectomy (VSG) vs Roux-en-Y gastric bypass (RYGB) for remission and relapse of dyslipidemia. DESIGN, SETTING, AND PARTICIPANTS This retrospective comparative effectiveness study was conducted from January 1, 2009, to December 31, 2016, with follow-up until December 31, 2018. Participants included patients with dyslipidemia at the time of surgery who underwent VSG (4142 patients) or RYGB (2853 patients). Patients were part of a large integrated health care system in Southern California. Analysis was conducted from January 1, 2018, to December 31, 2021. EXPOSURES RYGB and VSG. MAIN OUTCOMES AND MEASURES Dyslipidemia remission and relapse were assessed in each year of follow-up for as long as 4 years after surgery. RESULTS A total of 8265 patients were included, with a mean (SD) age of 46 (11) years; 6591 (79.8%) were women, 3545 (42.9%) were Hispanic, 1468 (17.8%) were non-Hispanic Black, 2985 (36.1%) were non-Hispanic White, 267 (3.2%) were of other non-Hispanic race, and the mean (SD) body mass index (calculated as weight in kilograms divided by height in meters squared) was 44 (7) at the time of surgery. Dyslipidemia outcomes at 4 years were ascertained for 2168 patients (75.9%) undergoing RYGB and 3999 (73.9%) undergoing VSG. Remission was significantly higher for those who underwent RYGB (824 [38.0%]) compared with VSG (1120 [28.0%]) (difference in the probability of remission, 0.10; 95% CI, 0.01-0.19), with no differences in relapse (455 [21.0%] vs 960 [24.0%]). Without accounting for relapse, remission of dyslipidemia after 4 years was 58.9% (1279) for those who underwent RYGB and 51.9% (2079) for those who underwent VSG. Four-year differences between operations were most pronounced for patients 65 years or older (0.39; 95% CI, 0.27-0.51), those with cardiovascular disease (0.43; 95% CI, 0.24-0.62), or non-Hispanic Black patients (0.13; 95% CI, 0.01-0.25) and White patients (0.13; 95% CI, 0.03-0.22). CONCLUSIONS AND RELEVANCE In this large, racially and ethnically diverse cohort of patients who underwent bariatric and metabolic surgery in clinical practices, RYGB was associated with higher rates of dyslipidemia remission after 4 years compared with VSG. However, almost one-quarter of all patients experienced relapse, suggesting that patients should be monitored closely throughout their postoperative course to maximize the benefits of these operations for treatment of dyslipidemia.

Abstract
Obesity is a complex metabolic condition considered a worldwide public health crisis, and a deeper mechanistic understanding of obesity-associated diseases is urgently needed. Obesity comorbidities include many associated cancers and are estimated to account for 20% of female cancer deaths in the USA. Breast cancer, in particular, is associated with obesity and is the focus of this review. The exact causal links between obesity and breast cancer remain unclear. Still, interactions have emerged between body mass index, tumor molecular subtype, genetic background, and environmental factors that strongly suggest obesity influences the risk and progression of certain breast cancers. Supportive preclinical research uses various diet-induced obesity models to demonstrate that weight loss, via dietary interventions or changes in energy expenditure, reduces the onset or progression of breast cancers. Ongoing and future studies are now aimed at elucidating the underpinning mechanisms behind weight-loss-driven observations to improve therapy and outcomes in patients with breast cancer and reduce risk. This review aims to summarize the rapidly emerging literature on obesity and weight loss strategies with a focused discussion of bariatric surgery in both clinical and preclinical studies detailing the complex interactions between metabolism, immune response, and immunotherapy in the setting of obesity and breast cancer.

Abstract
Short and long-term weight reduction interventions are considered in the preconception period for women and men with obesity and infertility as obesity is associated with poorer reproductive outcomes. Short-term weight loss achieved with diet, exercise, and medications does not improve per cycle conception or live birth rates in women undergoing ovulation induction, intrauterine insemination, or in vitro fertilization (IVF), but may increase the rate of natural conception. Long-term weight loss achieved through surgical interventions may increase spontaneous conceptions, particularly among women with polycystic ovary syndrome, and may increase the live birth rate from IVF, though these findings are limited by recent evidence. There is a clear need for additional treatment options and well-designed weight loss intervention trials that address the heterogeneous causes of obesity among women and men with infertility and include fertility outcomes and perinatal morbidity as outcome measures.

Abstract
Importance Long-term results from randomized clinical trials comparing laparoscopic sleeve gastrectomy (LSG) with laparoscopic Roux-en-Y-gastric bypass (LRYGB) are limited. Objective To compare long-term outcomes of weight loss and remission of obesity-related comorbidities and the prevalence of gastroesophageal reflux symptoms (GERD), endoscopic esophagitis, and Barrett esophagus (BE) after LSG and LRYGB at 10 years. Design, Setting, and Participants This 10-year observational follow-up evaluated patients in the Sleeve vs Bypass (SLEEVEPASS) multicenter equivalence randomized clinical trial comparing LSG and LRYGB in the treatment of severe obesity in which 240 patients aged 18 to 60 years with median body mass index of 44.6 were randomized to LSG (n = 121) or LRYGB (n = 119). The initial trial was conducted from April 2008 to June 2010 in Finland, with last follow-up on January 27, 2021. Interventions LSG or LRYGB. Main Outcomes and Measures The primary end point was 5-year percentage excess weight loss (%EWL). This current analysis focused on 10-year outcomes with special reference to reflux and BE. Results At 10 years, of 240 randomized patients (121 randomized to LSG and 119 to LRYGB; 167 women [69.6%]; mean [SD] age, 48.4 [9.4] years; mean [SD] baseline BMI, 45.9 [6.0]), 2 never underwent surgery and there were 10 unrelated deaths; 193 of the remaining 228 patients (85%) completed follow-up on weight loss and comorbidities, and 176 of 228 (77%) underwent gastroscopy. Median (range) %EWL was 43.5% (2.1%-109.2%) after LSG and 50.7% (1.7%-111.7%) after LRYGB. Mean estimate %EWL was not equivalent between the procedures; %EWL was 8.4 (95% CI, 3.1-13.6) higher in LRYGB. After LSG and LRYGB, there was no statistically significant difference in type 2 diabetes remission (26% and 33%, respectively; P = .63), dyslipidemia (19% and 35%, respectively; P = .23), or obstructive sleep apnea (16% and 31%, respectively; P = .30). Hypertension remission was superior after LRYGB (8% vs 24%; P = .04). Esophagitis was more prevalent after LSG (31% vs 7%; P < .001) with no statistically significant difference in BE (4% vs 4%; P = .29). The overall reoperation rate was 15.7% for LSG and 18.5% for LRYGB (P = .57). Conclusions and Relevance At 10 years, %EWL was greater after LRYGB and the procedures were not equivalent for weight loss, but both LSG and LRYGB resulted in good and sustainable weight loss. Esophagitis was more prevalent after LSG, but the cumulative incidence of BE was markedly lower than in previous trials and similar after both procedures.

Abstract
BACKGROUND Revision surgeries in patients with failed gastric banding including band removal are increasingly necessary. However, long-term outcomes after band removal alone are unsatisfactory due to weight regain and limited improvement in quality of life. This study aimed to report mid-term quality of life outcomes after gastric band removal and single-stage conversion to Roux-en-Y gastric bypass. METHODS Data of 108 patients who underwent conversion surgery from 2011 to 2017 were extracted from a prospective database and retrospectively analyzed. During follow-up visits, physical and laboratory data as well as quality of life questionnaires were obtained. RESULTS Postoperative mean Moorehead score increased significantly after 1 year (1.62 ± 0.86, p < 0.001) and after 5 years (1.55 ± 0.84, p < 0.001) compared to baseline values (0.72 ± 1.1). The mean follow-up time was 53 months. Moorehead scores at 1, 2, and 5 years postoperative were available in 75% (n = 81), 71% (n = 77), and 42% (n = 45) of cases, respectively. Mixed ANOVA analysis showed a significantly superior increase in Moorehead score in males (p = 0.024). No other significant predictors were identified. Lasting BMI reduction (- 4.6 to 33.0 ± 6.7 kg/m2, p < 0.001) and weight loss (- 12.9% (- 13.6 kg), p < 0.001) 5 years after conversion surgery were seen. Postoperative complications occurred in 35% (n = 38) of patients with a re-operation rate of 30.5% (n = 33). CONCLUSION The current study shows that band removal with single-stage gastric bypass in patients with failed gastric banding leads to a lasting improvement in quality of life and may be the rescue procedure of choice in this setting.

Abstract
The assessment and management of patient-reported outcomes (PROs) is considered secondary to that of cardiometabolic outcomes. When assessed, health-related quality of life (HRQOL), a PRO, can yield pertinent information that cannot be obtained from cardiometabolic assessments. For instance, physical and mental distress can be quantified and treated. Moreover, treatment convenience and satisfaction can be gaged. Behavioral modification, bariatric surgery, and pharmacotherapy can improve PROs. Typically, HRQOL is responsive to changes in weight. Specifically, weight loss and weight gain are associated with positive and negative changes in quality of life, respectively. In addition, patient satisfaction can be influenced by glycemic control. Therefore, hypoglycemia and hyperglycemic episodes can negatively affect patient satisfaction. When managing type 2 diabetes (T2D), it is important to consider how therapies impact PROs. Generally, changes in clinical outcomes mirror changes in PROs. To best manage T2D, integrating the assessment of PROs with clinical outcomes is needed.

Abstract
INTRODUCTION Obesity, defined as a body mass index ≥30 kg/m2, is one of the most prevalent health conditions worldwide. It is part of the metabolic syndrome, which encompasses arterial hypertension, dyslipoproteinaemia and diabetes. Obesity is viewed as a systemic disease with pathophysiological mechanisms on the molecular level. Dysfunction of the mitochondrion and systemic low-grade inflammation are among the proposed causes for the metabolic changes. In severe cases of obesity, laparoscopic sleeve gastrectomy, a bariatric operation, can achieve the desired weight loss and has been associated with clinical outcome improvement. Hitherto, the influence of patients' body composition on mitochondrial function and concomitant metabolic changes has not been fully understood. This study aims to quantify the patient's body composition before and after laparoscopic sleeve gastrectomy and to correlate these findings with changes in mitochondrial oxygen metabolism, metabolome and immune status. METHODS AND ANALYSIS In this prospective monocentric cohort study, patients undergoing laparoscopic sleeve gastrectomy (n=30) at Jena University Hospital (Germany) will be assessed before surgery and at four time points during a 1-year follow-up. Body composition will be measured by bioimpedance analysis. Non-invasive assessment of mitochondrial oxygen metabolism using protoporphyrin IX-triplet state lifetime technique (PPIX-TSLT) and blood sampling for, among other, metabolomic and immunological analysis, will be performed. The primary outcome is the difference in relative fat mass between the preoperative time point and 6 months postoperatively. Further outcomes comprise longitudinal changes of PPIX-TSLT and metabolic and immunological variables. Outcomes will be assessed using paired t-tests, Wilcoxon signed-rank tests and regression analyses. ETHICS AND DISSEMINATION The study was approved by the Ethics Committee of Friedrich Schiller University Jena (2018-1192-BO). Written informed consent will be obtained from all patients prior to enrolment in the study. The results will be published in peer-reviewed journals and presented at appropriate conferences. TRIAL REGISTRATION NUMBER DRKS00015891.

Abstract
OBJECTIVE The aim of this study was to compare clinical characteristics and adipose/liver tissue histology analysis in HIV-infected and HIV-uninfected subjects undergoing bariatric surgery. DESIGN This was a cross-sectional study of HIV-infected subjects undergoing single-port sleeve gastrectomy with prospective enrolment and frequency age (±5 years), sex, and body mass index (BMI, ± 5 kg/m2) matched on HIV-uninfected subjects. METHODS This study was conducted at a single clinical site at Pitié-Salpêtrière hospital-Paris-France comprising 19 HIV-uninfected and 21 HIV-infected subjects with plasma VL < 20 copies/mL, all with a BMI > 40 kg/m2 or >35 kg/m2 with comorbidities. Histology of subcutaneous and visceral abdominal adipose tissue (SCAT/VAT) and liver biopsies was collected during single-port sleeve gastrectomy. Outcomes included anthropometric characteristics, comorbidities, cardiovascular parameters, adipose tissue, and liver histology. RESULTS The age of HIV-infected participants was (median, interquartile range IQR) 48 y (42-51), with 76.2% females, a BMI of 41.4 kg/m2 (37.3-44.4), an antiretroviral duration of 16 y (8-21), current integrase strand transfer inhibitor (INSTI)-based regimen in 15 participants and non-INSTI regimen in 6 participants, and a CD4 count of 864/mm3 (560-1066). The age of controls was 43 y (37-51), with 78.9% females and a BMI of 39.2 kg/m2 (36.3-42.6). Anthropometric characteristics, comorbidities, and cardiovascular parameters did not differ according to HIV status and INSTI treatment. The number of macrophage crown-like structures in SCAT was lower in INSTI-treated participants than in HIV-uninfected participants (P = 0.02) and non-INSTI-treated HIV-infected subjects (P = 0.07). Hepatic steatosis and liver disease severity global score were lower in INSTI-treated participants than in non-INSTI-treated HIV-infected participants (P = 0.05 and P = 0.04, respectively). CONCLUSIONS HIV-infected and HIV-uninfected subjects undergoing bariatric surgery presented a similar profile regarding anthropometric measures, cardiovascular parameters, and comorbidities. However, INSTI-treated participants presented milder SCAT and liver alterations than non-INSTI-treated participants.

Late (≥5 y) Complications of Laparoscopic Vertical Sleeve Gastrectomy (LVSG) and Laparoscopic Roux-en-Y Gastric Bypass (LRYGB): A Systematic Review and Meta-analysis of Randomized Controlled Trials. Surg Laparosc Endosc Percutan Tech 2022; 32:501-513. [PMID: 35670641 DOI: 10.1097/sle.0000000000001065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Accepted: 03/31/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND There is a paucity of data that compares the relative complication profiles of laparoscopic vertical sleeve gastrectomy (LVSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) at 5 years. OBJECTIVES The aim was to compare late complications of LVSG and LRYGB. METHODS We updated our previous systematic review and meta-analysis of randomized controlled trials of primary LVSG and LRYGB procedures in adults, to review late (5 years) complication outcomes (PROSPERO 112054). Electronic databases were searched from January 2015 to July 2021 for publications meeting inclusion criteria. The Hartung-Knapp-Sidik-Jonkman random effects model was utilized to estimate weighted mean differences where meta-analysis was possible. Bias and certainty of evidence was assessed using the Cochrane risk of bias tool and Grading of Recommendations, Assessment, Development and Evaluations. RESULTS Four randomized controlled trials met the inclusion criteria (n=531; LVSG=272, LRYGB=259). No late treatment-related mortality was reported with either procedure. A significant reduction in surgical reoperations (odds ratio: 0.47, 95% confidence interval: 0.27-0.82, P=0.01) and endoscopic interventions (odds ratio: 0.29, 95% confidence interval: 0.12-0.71, P=0.02) were reported at 5 years post-LVSG relative to LRYGB. Reoperations were more frequently performed for reflux management in LVSG and for internal hernia repairs in LRYGB. Complications requiring medical management were common following both procedures. Limitations included few eligible studies for inclusion, and varying definitions of medically managed complications. CONCLUSIONS LRYGB is associated with a higher proportion of surgical and endoscopic interventions at 5 years compared with LVSG. More high-quality, long-term studies are required to further elucidate both surgical and nutritional long-term outcomes post these procedures.

Abstract
Introduction: According to the high rate of patients requiring a Re-Do surgery after a primary Sleeve Gastrectomy, due to failure on weight loss, this study proposes a comparison between RYGB and OAGB as a secondary intervention for morbidly obese patients. Methods: A retrospective review of patients who underwent revisional surgery to convert SG to RYGB or OAGB at our institution from November 2011 to November 2019 was performed. Results: A subset of sixty-three patients with previous SG underwent revisional surgery due to failure of the primary intervention. The OAGB group (n = 17) had a mean BMI at the time of the sleeve of 62 kg/m2 and a mean BMI of 50.7 kg/m2, the length of the Omega was 139.35 cm. The RYGB (n = 46) group showed a mean BMI of 47 kg/m2 at the time of the sleeve and a BMI of 34.8 kg/m2 at the time of the revision. The RYGB was performed according to the 70/120 cm standard for all the patients. One patient also had a revision from secondary OAGB to RYGB due to persistent biliary reflux, in this case the biliary branch was settled at 150 cm and the alimentary at 50 cm. Conclusions: The outcomes in the OAGB group showed a 29%WL and a 47%EWL (out of a 17%WL and 28%EWL at the time of the sleeve), on the other side the RYGB group reached a 33%WL and 72%EWL (out of a 25%WL and a 54%EWL at the time of the sleeve). According to our data we assume that RYGB is more effective in terms of weight loss as a revisional surgery after sleeve

Abstract
OBJECTIVE This study aimed to determine which bariatric procedure allows patients to obtain the best weight-loss outcomes and a remission of type 2 diabetes. METHODS Databases were searched for randomized-controlled trials comparing Roux-en-Y gastric bypass (RYGB) with sleeve gastrectomy (SG) or one-anastomosis gastric bypass (OAGB). The mean difference (MD) or the relative risk was determined. RESULTS Twenty-five randomized-controlled trials were analyzed. Excess weight loss (EWL, percentage) was greater for RYGB patients at 3 years (MD: 11.93, p < 0.00001) and 5 years (MD: 13.11, p = 0.0004). Higher excess BMI loss (percentage) was found in RYGB at 1 year (MD: 11.66, p = 0.01). Total weight loss (percentage) was greater for RYGB patients after 3 months (MD: 2.41, p = 0.02), 6 months (MD: 3.83, p < 0.00001), 1 year (MD: 6.35, p < 0.00001), and 5 years (MD: 3.90, p = 0.005). No difference in terms of remission of type 2 diabetes was seen between RYGB and SG. EWL was significantly more important after OAGB than after RYGB after 1 year (MD: -10.82, p = 0.003). CONCLUSIONS RYGB is more efficient than SG in the midterm. OAGB offers greater EWL than RYGB after 1 year, but further evidence is needed to confirm this result.

Abstract
BACKGROUND The European Association for Endoscopic Surgery Bariatric Guidelines Group identified a gap in bariatric surgery recommendations with a structured, contextualized consideration of multiple bariatric interventions. OBJECTIVE To provide evidence-informed, transparent and trustworthy recommendations on the use of sleeve gastrectomy, Roux-en-Y gastric bypass, adjustable gastric banding, gastric plication, biliopancreatic diversion with duodenal switch, one anastomosis gastric bypass, and single anastomosis duodeno-ileal bypass with sleeve gastrectomy in patients with severe obesity and metabolic diseases. Only laparoscopic procedures in adults were considered. METHODS A European interdisciplinary panel including general surgeons, obesity physicians, anesthetists, a psychologist and a patient representative informed outcome importance and minimal important differences. We conducted a systematic review and frequentist fixed and random-effects network meta-analysis of randomized-controlled trials (RCTs) using the graph theory approach for each outcome. We calculated the odds ratio or the (standardized) mean differences with 95% confidence intervals for binary and continuous outcomes, respectively. We assessed the certainty of evidence using the CINeMA and GRADE methodologies. We considered the risk/benefit outcomes within a GRADE evidence to decision framework to arrive at recommendations, which were validated through an anonymous Delphi process of the panel. RESULTS We identified 43 records reporting on 24 RCTs. Most network information surrounded sleeve gastrectomy and Roux-en-Y gastric bypass. Under consideration of the certainty of the evidence and evidence to decision parameters, we suggest sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass over adjustable gastric banding, biliopancreatic diversion with duodenal switch and gastric plication for the management of severe obesity and associated metabolic diseases. One anastomosis gastric bypass and single anastomosis duodeno-ileal bypass with sleeve gastrectomy are suggested as alternatives, although evidence on benefits and harms, and specific selection criteria is limited compared to sleeve gastrectomy and Roux-en-Y gastric bypass. The guideline, with recommendations, evidence summaries and decision aids in user friendly formats can also be accessed in MAGICapp: https://app.magicapp.org/#/guideline/Lpv2kE CONCLUSIONS: This rapid guideline provides evidence-informed, pertinent recommendations on the use of bariatric and metabolic surgery for the management of severe obesity and metabolic diseases. The guideline replaces relevant recommendations published in the EAES Bariatric Guidelines 2020.

Abstract
IMPORTANCE Sleeve gastrectomy and gastric bypass are the most common bariatric surgical procedures in the world; however, their long-term medication discontinuation and comorbidity resolution remain unclear. OBJECTIVE To compare the incidence of medication discontinuation and restart of diabetes, hypertension, and hyperlipidemia medications up to 5 years after sleeve gastrectomy or gastric bypass. DESIGN, SETTING, AND PARTICIPANTS This comparative effectiveness research study of adult Medicare beneficiaries who underwent laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass between January 1, 2012, to December 31, 2018, and had a claim for diabetes, hypertension, or hyperlipidemia medication in the 6 months before surgery with a corresponding diagnosis used instrumental-variable survival analysis to estimate the cumulative incidence of medication discontinuation and restart. Data analyses were performed from February to June 2021. EXPOSURES Laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass. MAIN OUTCOMES AND MEASURES The primary outcome was discontinuation of diabetes, hypertension, and hyperlipidemia medication for any reason. Among patients who discontinued medication, the adjusted cumulative incidence of restarting medication was calculated up to 5 years after discontinuation. RESULTS Of the 95 405 patients included, 71 348 (74.8%) were women and the mean (SD) age was 56.6 (11.8) years. Gastric bypass compared with sleeve gastrectomy was associated with a slightly higher 5-year cumulative incidence of medication discontinuation among 30 588 patients with diabetes medication use and diagnosis at the time of surgery (74.7% [95% CI, 74.6%-74.9%] vs 72.0% [95% CI, 71.8%-72.2%]), 52 081 patients with antihypertensive medication use and diagnosis at the time of surgery (53.3% [95% CI, 53.2%-53.4%] vs 49.4% [95% CI, 49.3%-49.5%]), and 35 055 patients with lipid-lowering medication use and diagnosis at the time of surgery (64.6% [95% CI, 64.5%-64.8%] vs 61.2% [95% CI, 61.1%-61.3%]). Among the subset of patients who discontinued medication, gastric bypass was also associated with a slightly lower incidence of medication restart up to 5 years after discontinuation. Specifically, the 5-year cumulative incidence of medication restart was lower after gastric bypass compared with sleeve gastrectomy among 19 599 patients who discontinued their diabetes medication after surgery (30.4% [95% CI, 30.2%-30.5%] vs 35.6% [95% CI, 35.4%-35.9%]), 21 611 patients who discontinued their antihypertensive medication after surgery (67.2% [95% CI, 66.9%-67.4%] vs 70.6% [95% CI, 70.3%-70.9%]), and 18 546 patients who discontinued their lipid-lowering medication after surgery (46.2% [95% CI, 46.2%-46.3%] vs 52.5% [95% CI, 52.2%-52.7%]). CONCLUSIONS AND RELEVANCE Findings of this study suggest that, compared with sleeve gastrectomy, gastric bypass was associated with a slightly higher incidence of medication discontinuation and a slightly lower incidence of medication restart among patients who discontinued medication. Long-term trials are needed to explain the mechanisms and factors associated with differences in medication discontinuation and comorbidity resolution after bariatric surgery.

Abstract
Background The laparoscopic sleeve gastrectomy (LSG) and the incisionless endoscopic sleeve gastroplasty (ESG) weight loss procedures require further investigation of their efficacy, safety and patient-centered outcomes in the Australian setting. Methods The aim was to examine the 6- and 12-month weight loss efficacy, safety, and weight-related quality of life (QoL) of adults with obesity who received the ESG or LSG bariatric procedure with 12+ months of adjuvant multidisciplinary pre- and postprocedural support. Data were from a two-arm prospective cohort study that followed patients from baseline to 12-months postprocedure from a medical center in Queensland. Percent excess weight loss (%EWL) was the primary outcome. Secondary outcomes were body composition (fat mass, fat-free mass, android:gynoid ratio, bone mineral content) via dual energy X-ray absorptiometry, weight-related QoL, lipid, glycemic, and hepatic biochemistry, and adverse events. Results 16 ESG (19% attrition; 81.2% female; aged:41.4 (SD: 10.4) years; BMI: 35.5 (SD: 5.2) kg/m2) and 45 LSG (9% attrition; 84.4% female; aged:40.4 (SD: 9.0) years; BMI: 40.7 (SD: 5.6) kg/m2) participants were recruited. At 12-months postprocedure, ESG %EWL was 57% (SD: 32%; p < 0.01) and LSG %EWL was 79% (SD: 24%; p < 0.001). ESG and LSG cohorts improved QoL (19.8% in ESG [p > 0.05]; 48.1% in LSG [p < 0.05]), liver function (AST: − 4.4 U/L in ESG [p < 0.05]; − 2.7 U/L in LSG [p < 0.05]), HbA1c (− 0.5% in ESG [p < 0.05]; − 0.1% in LSG [p < 0.05]) and triglycerides (− 0.6 mmol/L in ESG [p > 0.05]; − 0.4 mmol/L in LSG [P < 0.05]) at 12-months. Both cohorts reduced fat mass (p < 0.05). The ESG maintained but LSG decreased fat-free mass at 6-months (p < 0.05); and both cohorts lost fat-free mass at 12-months (p < 0.05). There were no adverse events directly related to the procedure. The ESG reported 25% mild-moderate adverse events possibly related to the procedure, and the LSG reported 27% mild-severe adverse events possibly related to the procedure. Conclusions In this setting, the ESG and LSG were safe and effective weight loss treatments for obese adults alongside multidisciplinary support. Patients who elected the ESG maintained fat-free mass at 6-months but both cohorts lost fat-free mass at 12-months postprocedure. Patients who elected the LSG had large and significant improvements to weight-related quality of life. Further well-powered studies are required to confirm these findings.

Abstract
BACKGROUND In 2017, the prevalence of obesity (BMI ≥= 30 kg/m2) in Germany was approximately 16%. Obesity increases an individual's risk of developing type 2 diabetes (T2DM) and arterial hypertension; it also increases overall mortality. Consequently, effective treatment is a necessity. Approximately 20 000 bariatric operations are performed in Germany each year. METHODS This review is based on pertinent publications retrieved by a selective search in the PubMed and Cochrane databases and on current German clinical practice guidelines. RESULTS The types of obesity surgery most commonly performed in Germany, Roux-en-Y gastric bypass and sleeve gastrectomy, lead to an excess weight loss of 27-69% ≥= 10 years after the procedure. In obese patients with T2DM, the diabetes remission rate ≥= 10 years after these procedures ranges from 25% to 62%. Adjusted regression analyses of data from large registries have shown that the incidence of malignancies is 33% lower in persons who have undergone obesity surgery compared to control subjects with obesity (unadjusted incidence 5.6 versus 9.0 cases per 1000 person-years). The operation can cause vitamin deficiency, surgical complications, gastroesophageal reflux, and dumping syndrome. Therefore, lifelong follow-up is necessary. CONCLUSION In view of an increasing number of patients undergoing bariatric surgery, it will probably not be feasible in the future for lifelong follow-up to be provided exclusively in specialized centers.

Outcome of Sleeve Gastrectomy Converted to Roux-en-Y Gastric Bypass and One-Anastomosis Gastric Bypass. Obes Surg 2022; 32:643-651. [PMID: 35028871 PMCID: PMC8866292 DOI: 10.1007/s11695-021-05866-0] [Citation(s) in RCA: 24] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Revised: 12/19/2021] [Accepted: 12/22/2021] [Indexed: 11/19/2022]
Abstract
Purpose Sleeve gastrectomy (SG) is the commonest bariatric procedure worldwide but there is also a high conversion rate mainly due to weight regain and gastroesophageal reflux disease (GERD) reported in studies with long-term follow-up. The aim of this study is to highlight benefits and limitations of converting SG patients to Roux-en-Y gastric bypass (RYGB) and one-anastomosis gastric bypass (OAGB). Setting Retrospective cross-sectional-study, medical university clinic setting. Methods This study includes all patients converted from primary SG to RYGB or OAGB by 12/2018 at the Medical University of Vienna. Patients were examined using gastroscopy, esophageal manometry, 24-h pH-metry, and questionnaires. Results Fifty-eight patients were converted from SG to RYGB (n = 45) or OAGB (n = 13). Total weight loss of patients converted to RYGB and OAGB was 41.5% and 44.8%, respectively, at nadir. Six patients had Barrett’s esophagus (BE) after SG. In four out of these six patients, a complete remission of BE after conversion to RYGB was observed; nevertheless, two patients after RYGB and one after OABG newly developed BE. Clinical GERD improved at a higher rate after RYGB than after OAGB. Both revisional procedures improved associated medical problems. Conclusion Conversion to RYGB is probably the best option for patients with GERD after SG. OAGB has shown a low potential to cure patients from GERD symptoms after SG. In terms of additional weight loss and remission of associated medical problems, both procedures studied were equal. Surveillance gastroscopies every 5 years after SG revisions are recommended.

Seven-year trajectories of body weight, quality of life and comorbidities following Roux-en-Y gastric bypass and sleeve gastrectomy. Int J Obes (Lond) 2022; 46:739-749. [PMID: 34974544 PMCID: PMC8960397 DOI: 10.1038/s41366-021-01028-5] [Citation(s) in RCA: 36] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 11/08/2021] [Accepted: 11/16/2021] [Indexed: 01/03/2023]
Abstract
BACKGROUND/OBJECTIVES There is limited long-term data comparing the outcomes of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) for severe obesity, both with respect to body weight, quality of life (QOL) and comorbidities. We aimed to determine 7-year trajectories of body mass index (BMI), QOL, obesity-related comorbidities, biomarkers of glucose and lipid metabolism, and early major complications after SG and RYGB. SUBJECTS/METHODS Patients scheduled for bariatric surgery at two Norwegian hospitals, preferentially performing either SG or RYGB, were included consecutively from September 2011 to February 2015. Data was collected prospectively before and up to 7 years after surgery. Obesity-specific, generic and overall QOL were measured by the Impact of Weight on Quality of Life-Lite, Short-Form 36 and Cantril's ladder, respectively. Comorbidities were assessed by clinical examination, registration of medication and analysis of glucose and lipid biomarkers. Outcomes were examined with linear mixed effect models and relative risk estimates. RESULTS Of 580 included patients, 543 (75% women, mean age 42.3 years, mean baseline BMI 43.0 kg/m2) were operated (376 SG and 167 RYGB). With 84.2% of participants evaluable after 5-7 years, model-based percent total weight-loss (%TWL) at 7 years was 23.4 after SG versus 27.3 after RYGB (difference 3.9%, p = 0.001). All levels of QOL improved similarly after the two surgical procedures but remained below reference data from the general population at all timepoints. Remission rates for type 2 diabetes, dyslipidemia, obstructive sleep-apnea and gastroesophageal reflux disease (GERD) as well as the rate of de novo GERD significantly favored RYGB. SG had fewer major early complications, but more minor and major late complications combined over follow-up. CONCLUSION In routine health care, both SG and RYGB are safe procedures with significant long-term weight-loss, improvement of QOL and amelioration of comorbidities. Long-term weight-loss and remission rates of main obesity-related comorbidities were higher after RYGB.

Front Endocrinol (Lausanne) 2022; 13:1072513. [PMID: 36619535 PMCID: PMC9810748 DOI: 10.3389/fendo.2022.1072513] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 12/08/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is associated with obesity and insulin resistance and can be improved after bariatric surgery. Circulating Peroxiredoxin 1 (Prdx1) protein was reported to regulate energy metabolism and inflammation. This study aimed to investigate the roles of serum prdx1 in NAFLD patients with obesity undergoing LSG and to develop a prognostic model to predict the remission of severe NAFLD. METHODS The data of 93 participants from a tertiary hospital were assessed. Before laparoscopic sleeve gastrectomy (LSG) and three months after LSG, anthropometric parameters, laboratory biochemical data, and abdominal B-ultrasound results were collected, and their hepatic steatosis index (HSI) and triglyceride-glucose index (TyG) were calculated. A NAFLD improvement (NAFLD-I) nomogram prediction model was constructed using the least absolute shrinkage and selection operator (LASSO) regression and multiple regression, and its predictive ability was verified in a validation cohort. RESULTS The baseline Prdx1 (OR: 0.887, 95% CI: 0.816-0.963, p=0.004), preoperative TyG (OR: 8.207, 95% CI: 1.903-35.394, p=0.005) and HSI (OR: 0.861, 95% CI: 0.765-0.969, p=0.013) levels were independently associated with NAFLD-I at three months after LSG in NAFLD patients with obesity. In the primary and validation cohorts, the area under the receiver operating characteristic (AUC) of the developed nomogram model was 0.891 and 0.878, respectively. The preoperative circulating Prdx1 levels of NAFLD patients with obesity were significantly reduced after LSG (25.32 [18.99-30.88] vs. 23.34 [15.86-26.42], p=0.001). Prdx1 was related to obesity and hepatic steatosis based on correlation analysis. CONCLUSION The nomogram based on preoperative serum prdx1, HSI and TyG could be an effective tool for predicting remission of severe NAFLD after LSG.
