Lytvyak E, Zarrinpar A, Ore CD, Lee E, Yazdani-Boset K, Horgan S, Grunvald E. Stronger control of eating 3 months after sleeve gastrectomy predicts successful weight loss outcomes at one year. OBESITY PILLARS 2024; 11:100111. [PMID: 38770521 PMCID: PMC11103426 DOI: 10.1016/j.obpill.2024.100111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/23/2024] [Revised: 05/01/2024] [Accepted: 05/02/2024] [Indexed: 05/22/2024]
Abstract
Background Weight loss response to sleeve gastrectomy (SG) is variable and predicting the effectiveness of surgery is challenging and elusive. The aim of our study was to assess and quantify the association between eating control and weight loss outcomes and identify the control of eating (CoE) attributes during the early postoperative period that might predict good vs. poor response to SG at one year. Methods A prospective longitudinal cohort study using the Control of Eating Questionnaire (CoEQ) was designed as a series before and at 3-, 6-, and 12-months post-SG. Primary outcomes were changes in CoE attributes and percent of total weight loss (%TWL) 12-months post-surgery. Subjects were categorized based on %TWL as good (GR, ≥25 %) or poor responders (PR, <25 %). A receiver operating characteristic and logistic regression analyses were performed. Results We included 41 participants (80.5% females, 51.2% Hispanic, mean age 41.7±10.6, median baseline body mass index (BMI) 43.6 kg/m2 [range 35.2-66.3]) who completed the CoEQ at all four timepoints. The "Difficulty to control eating" score at 3 months revealed the highest area under the curve (AUC) (AUC 0.711; 95%CI 0.524-0.898; p=0.032). In a trade-off between a high Youden index and high sensitivity, the "Difficulty to control eating" score of 7 at 3 months was identified as the optimal cut-off for distinguishing between GRs and PRs. Score ≤7 at 3 months was strongly independently associated with a successful weight loss target of 25%TWL at one-year post-SG (Relative Risk 4.43; 95%CI 1.06-18.54; p=0.042). Conclusion "Difficulty to control eating" score at 3 months post-SG is an independent early predictor of optimal response (achieving a successful TWL target of ≥25 % at one-year post-SG). Our results support the utility of this easy-to-administer validated tool for predicting the effectiveness of SG and may assist in identifying individuals with suboptimal response early and helping them with interventions to attain optimal weight loss targets.

Analysis of correlation between BMI and TWL% outcome following metabolic and bariatric surgery: a retrospective study using restricted cubic spline. BMC Surg 2024; 24:178. [PMID: 38849774 PMCID: PMC11157919 DOI: 10.1186/s12893-024-02455-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Accepted: 05/16/2024] [Indexed: 06/09/2024] Open
Abstract
OBJECTIVE This study aimed to examine the correlation between preoperative body mass index (BMI) and adequate percentage of total weight loss (TWL%) outcome and present evidence of tiered treatment for patients with obesity in different preoperative BMI. METHODS We included patients with complete follow-up data who underwent metabolic and bariatric surgery (BMS). We termed optimal clinical response as TWL% >20% at one year following MBS. To investigate dose-response association between preoperative BMI and optimal clinical response, preoperative BMI was analyzed in three ways: (1) as quartiles; (2) per 2.5 kg/m2 units (3) using RCS, with 3 knots as recommended. RESULTS A total of 291 patients with obesity were included in our study. The corresponding quartile odds ratios associated with optimal clinical response and adjusted for potential confounders were 1.00 (reference), 1.434 [95% confidence interval (95%CI) = 0.589-3.495], 4.926 (95%CI = 1.538-15.772), and 2.084 (95%CI = 0.941-1.005), respectively. RCS analysis showed a non-linear inverted U-shaped association between preoperative BMI and optimal clinical response (Nonlinear P = 0.009). In spline analysis, when preoperative BMI was no less than 42.9 kg/m2, the possibility of optimal clinical response raised as preoperative BMI increased. When preoperative BMI was greater than 42.9 kg/m2, the possibility of optimal clinical response had a tendency to decline as preoperative BMI increased. CONCLUSION Our research indicated the non-linear inverted U-shaped correlation between preoperative BMI and adequate weight loss. Setting a preoperative BMI threshold of 42.9 is critical to predicting optimal clinical outcomes.

J Gastrointest Surg 2024:S1091-255X(24)00485-2. [PMID: 38821212 DOI: 10.1016/j.gassur.2024.05.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 05/19/2024] [Accepted: 05/27/2024] [Indexed: 06/02/2024]
Abstract
BACKGROUND Bariatric surgery is currently the most effective long-term treatment for severe obesity. However, the interindividual variability observed in surgical outcomes suggests a moderating effect of several factors, including individual genetic background. Our goal was to investigate the contribution of the genetic architecture of BMI to the variability in weight loss outcomes after bariatric surgery. METHODS A total of 106 patients with severe obesity who underwent Roux-en-Y gastric bypass or sleeve gastrectomy were followed up for five years. Changes in body mass index (BMIchange) and percentage of total weight loss (%TWL) were evaluated during the postoperative period. Polygenic risk scores including 50 genetic variants were calculated for each participant to determine their individual genetic risk for high BMI based on a previous GWAS. Generalized estimating equation models were used to study the role of the individual's polygenic score, as well as other factors, on BMIchange and %TWL in the long term after surgery. RESULTS We found an effect of the polygenic score on %TWL and BMIchange, where subjects with lower scores had better outcomes after surgery than those with higher scores. Furthermore, when analyzing only patients who underwent Roux-en-Y gastric bypass, these results were replicated showing greater weight loss after surgery for those with lower polygenic scores. DISCUSSION These results indicate that genetic background assessed with polygenic risk scores, along with other individual factors such as sex, age, and preoperative BMI, has an impact on bariatric surgery outcomes and could represent a useful tool for estimating surgical outcomes in advance.

Abstract
Bariatric surgery therapy (BST) is an effective treatment for obesity; however, little is known about its impacts on health-related quality of life (HRQoL) and related factors. This study aimed to evaluate changes in HRQoL and its relationship with weight loss, depression status, physical activity (PA), and nutritional habits after BST. Data were obtained before and 18 months postprocedure from 56 obese patients who underwent BST. We administered four questionnaires: Short Form-36 health survey for HRQoL, 14-item MedDiet adherence questionnaire, Rapid Assessment of PA (RAPA) questionnaire, and Beck's Depression Inventory-II. Multivariable linear regression analysis was used to identify factors associated with improvement in HRQoL. After the surgery, MedDiet adherence and HRQoL improved significantly, especially in the physical component. No changes in PA were found. Patients without previous depression have better mental quality of life, and patients who lost more than 25% of %TBWL have better results in physical and mental quality of life. In the multivariable analysis, we found that %TBWL and initial PCS (inversely) were related to the improvement in PCS and initial MCS (inversely) with the MCS change. In conclusion, BST is an effective intervention for obesity, resulting in significant weight loss and improvements in HRQoL and nutritional habits.

Obes Surg 2024; 34:1618-1629. [PMID: 38502520 DOI: 10.1007/s11695-024-07158-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 03/05/2024] [Accepted: 03/06/2024] [Indexed: 03/21/2024]
Abstract
PURPOSE Sleeve gastrectomy (SG) is a commonly performed metabolic-bariatric surgery, but its effectiveness is variable and difficult to predict. Our study aimed to compare control of eating (CoE) attributes pre- and post-SG depending on the achievement of optimal weight loss target at 1 year post-SG. MATERIALS AND METHODS A prospective longitudinal cohort study using the CoE Questionnaire, pre-SG, and postoperatively at 3, 6, and 12 months was conducted. Total weight loss (TWL) ≥ 25% at 12 months post-SG was set as an optimal weight loss target. RESULTS Forty-one patients (80.5% females, mean age 41.7 ± 10.6) were included. Sex, age, baseline weight, BMI, and smoking status were all comparable. At 3 months post-SG, "difficulty to control eating" score became significantly different between ≥ 25%TWL and < 25%TWL groups (7 [0-50] vs. 17 [5-63], p = 0.042). At 6 months, it was followed by "feeling of fullness," "frequency of food cravings," and "difficulty to resist cravings" demonstrating significant differences between ≥ 25%TWL and < 25%TWL groups. At 12 months, significant differences between groups were observed in "feeling hungry," "difficulty to resist cravings," "eating in response to cravings," and difficulty to control eating scores. CONCLUSION Individuals with obesity who achieved a target of ≥ 25%TWL at 1 year post-SG have an early improvement in overall eating control at 3 months that steadily persists at 6 and 12 months. Improvements in other aspects tend to follow later, at 6 and 12 months. These findings may assist in identifying individuals with inadequate response to help attain optimal weight loss targets and developing a prognostic model to identify predictors of successful weight loss.

Abstract
BACKGROUND Less than 50% of eligible candidates who are referred complete Bariatric Metabolic Surgery (BMS). The factors influencing the decision to complete BMS, particularly how these factors vary across different racial and ethnic groups, remain largely unexplored. METHODS This prospective cohort study included adult patients referred to a bariatric surgeon or obesity medicine program between July 2019-September 2022. Sociodemographic characteristics, body mass index (BMI), anxiety, depression, body appreciation, and patient-physician relationship information were collected via survey and electronic health records. The association between BMS completion and potential decision-driving factors was examined using Classification and Regression Tree (CART) analysis. RESULTS A total of 406 BMS -eligible patients participated in the study (mean [SD] age: 47.5 [11.6] years; 87.2% women; 18.0% Hispanic, 39% non-Hispanic Black [NHB], and 39% non-Hispanic White [NHW]; mean [SD] BMI: 45.9 [10.1] kg/m2). A total of 147 participants (36.2%) completed BMS. Overall, the most influential factor driving the decision to complete BMS was younger age (< 68.4 years), higher patient satisfaction, and BMI (≥ 38.0 kg/m2). Hispanic participants prioritized age (< 55.4 years), female sex, and body appreciation. For NHB participants, the highest ranked factors were age < 56.3 years, BMI ≥ 35.8 kg/m2, and higher patient satisfaction. For NHW patients, the most influential factors were age (39.1 to 68.6 years) and higher body appreciation. CONCLUSION These findings highlight racial and ethnic group differences in the factors motivating individuals to complete BMS. By acknowledging these differences, healthcare providers can support patients from different backgrounds more effectively in their decision-making process regarding BMS.

Pre-operative body shape concerns moderate excess weight loss trajectory in bariatric surgery patients: a 2-year longitudinal study. Eat Weight Disord 2024; 29:30.

Abstract
PURPOSE The main research aim was to inspect whether pre-operative body shape concerns and discomfort as Body Shape Questionnaire (BSQ) scores moderate post-operative weight loss trajectory in bariatric patients. METHODS Two studies were conducted. Study 1 analyzed cross-sectional data and verified the structural validity of the 34-item BSQ questionnaire on a sample of 327 candidates for bariatric surgery. Study 2 examined longitudinal data, with objective Body Mass Index (BMI) recorded every 6 months, from surgery intervention on, with 5 measurement occasions, from 111 patients who initially completed BSQ as bariatric surgery candidates and then underwent periodic medical post-operative follow-ups, over 2 years. RESULTS In Study 1, confirmatory factor analysis of a single-dimension model yielded acceptable fit indices and high internal consistency levels. Study 2 showed that post-operative excess BMI reduction trend was not linear and pre-operative BSQ scores moderated it, with a higher risk of weight regain in patients who initially were less concerned with their body shape. CONCLUSIONS The present findings support the structural validity of the BSQ questionnaire in bariatric candidates and call attention on the role of pre-operative body shape concerns on post-operative weight loss trajectories over 2 years, in accordance with a pathoplasty model. They suggest the need for systematic attention on perceived body image and psychological paths aimed to help bariatric patients regain positive attitudes towards their own body. Level of evidence III, well-designed cohort.

Abstract
INTRODUCTION The purpose of this study is to investigate the impact of preoperative comorbidities, including depression, anxiety, type 2 diabetes mellitus, obstructive sleep apnea, hypothyroidism, and the type of surgery on %EBWL (percent estimated body weight loss) in patients 1 year after bariatric surgery. Patients who choose to undergo bariatric surgery often have other comorbidities that can affect both the outcomes of their procedures and the postoperative period. We predict that patients who have depression, anxiety, diabetes mellitus, obstructive sleep apnea, or hypothyroidism will have a smaller change in %EBWL when compared to patients without any of these comorbidities. METHODS AND PROCEDURES Data points were retrospectively collected from the charts of 440 patients from March 2012-December 2019 who underwent a sleeve gastrectomy or gastric bypass surgery. Data collected included patient demographics, select comorbidities, including diabetes mellitus, obstructive sleep apnea, hypothyroidism, depression, and anxiety, and body weight at baseline and 1 year postoperatively. Ideal body weight was calculated using the formula 50 + (2.3 × height in inches over 5 feet) for males and 45.5 + (2.3 × height in inches over 5 feet) for females. Excess body weight was then calculated by subtracting ideal body weight from actual weight at the above forementioned time points. Finally, %EBWL was calculated using the formula (change in weight over 1 year/excess weight) × 100. RESULTS Patients who had a higher baseline BMI (p < 0.001), diabetes mellitus (p = 0.026), hypothyroidism (p = 0.046), and who had a laparoscopic sleeve gastrectomy rather than Roux-en-Y gastric bypass (p < 0.001) had a smaller %EBWL in the first year after bariatric surgery as compared to patients without these comorbidities at the time of surgery. Controversially, patients with anxiety or depression (p = 0.73) or obstructive sleep apnea (p = 0.075) did not have a statistically significant difference in %EBWL. CONCLUSION A higher baseline BMI, diabetes mellitus, hypothyroidism, and undergoing laparoscopic sleeve gastrectomy may lead to lower %EBWL in the postoperative period after bariatric surgery. At the same time, patients' mental health status and sleep apnea status were not related to %EBWL. This study provides new insight into which comorbidities may need tighter control in order to optimize weight loss outcomes after bariatric surgery.

Longitudinal trajectories and psychological predictors of weight loss and quality of life until 3 years after metabolic and bariatric surgery. J Psychosom Res 2024; 178:111590. [PMID: 38237524 DOI: 10.1016/j.jpsychores.2024.111590] [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: 10/20/2023] [Revised: 12/11/2023] [Accepted: 01/07/2024] [Indexed: 03/17/2024]
Abstract
OBJECTIVE This study aimed to describe longitudinal trajectories of Total Weight Loss (%TWL), and mental and physical health related quality of life (HRQOL), as well as to identify preoperative psychological predictors of these trajectories. METHODS A prospective observational study including Dutch patients treated with metabolic and bariatric surgery (n = 420, age 44.8 ± 10.3 years, 78.6% females) was performed. Trajectories of %TWL and HRQOL from screening to 1-, 2-, and 3-years post-surgery were described using growth mixture modelling. Multivariable and lasso regression models were used to identify predictors. RESULTS Three trajectories described %TWL, varying in the degree of first-year weight loss. No pre-surgical psychological factors were associated with %TWL trajectories. We identified four physical and five mental HRQOL trajectories. Approximately 25-30% of patients exhibited patterns of initial improvements followed by decline, or persistently low levels of HRQOL. Higher depressive symptoms were associated with these unfavourable physical HRQOL trajectories (OR 1.20, 95%CI 1.04-1.39), adjusted for confounders. Unfavourable mental HRQOL trajectories were predicted by depressive and anxiety symptoms, neuroticism, insecure attachment, and maladaptive coping. In contrast, self-esteem, extraversion, and conscientiousness were associated with favourable mental HRQOL trajectories. DISCUSSION Psychological factors did not predict weight loss, but they significantly impacted patient's HRQOL after metabolic and bariatric surgery. A subgroup with unsuccessful HRQOL after surgery was identified, who would benefit from tailored preoperative counselling to optimize surgery outcomes. Metabolic and bariatric surgery may not be universally beneficial for all patients, challenging the conventional approach to surgical interventions for severe obesity and advocating for a more nuanced, individualized assessment of potential candidates.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure worldwide. Many factors have been investigated in the literature to predict weight loss outcomes after LSG. However, insufficient data regarding the resected stomach weight (RGW) exists. This retrospective study aimed to investigate the association between RGW and weight loss outcomes 1 year after LSG. MATERIALS AND METHODS Fifty-four patients who underwent LSG in a tertiary care center were evaluated retrospectively. The statistical analyses were performed to investigate the correlation between preoperative demographics, RGW, and the excess weight loss percentage (%EWL) and percent total weight loss (%TWL). RESULTS The mean RGW was 169.7±40.1, ranging from 101 to 295 grams. The RGW was significantly correlated with preoperative weight (r=0.486; P<0.001), body mass index (r=0.420; P=0.002), and age (r=0.327; P=0.01). However, RGW did not predict postoperative weight loss, as measured by percent total weight loss (%TWL) and percent excess weight loss (%EWL), respectively (r=0.044; P=0.75 and r=-0.216; P=0.11). Multiple linear regression analysis identified age as a negative predictor for both %TWL (β=-0.351, P=0.005) and %EWL (β=-0.265, P=0.03), while preoperative body mass index was a negative predictor for %EWL (β=-0.469, P<0.001). CONCLUSION The RGW, although correlated with patient characteristics, does not serve as a reliable predictor of postoperative weight loss in the first year after LSG. Further research is needed to improve predictive models and patient care in bariatric surgery.

Abstract
Introduction: The overexpression of proinflammatory cytokines in obesity has suggested an association between obesity and inflammation. In this study, we aimed to predict the success of weight loss at the end of the first year of patients who underwent laparoscopic sleeve gastrectomy (LSG) for morbid obesity using hemoglobin, albumin, lymphocyte, and platelet (HALP) score and modified HALP (m-HALP) score. Materials and Methods: Patients were divided into two groups according to the success of weight loss. The groups were compared in terms of HALP score, m-HALP score, demographic parameters, and preoperative laboratory tests. The diagnostic performance measurements of the m-HALP score were calculated. In addition, logistic regression analysis was performed for the factors affecting weight loss in the first year after LSG. Results: Seventy-two patients were evaluated. The median m-HALP score of the patients with an excess weight loss percentage (EWL%) <60 threshold was 562 (416.6-891.9), the median m-HALP score of the patients with an EWL% above the 60 threshold was 394.3 (347.9-543), and the difference between the outcome groups was significant (P = .002).The accuracy of m-HALP score in identifying the patients whose EWL would be <60% 1 year after the surgery was 63.9 (95% confidence interval = 51.7-74.9). Conclusion: This study showed that the m-HALP score is effective in predicting weight loss after bariatric surgery.

Abstract
INTRODUCTION Endoscopic sleeve gastroplasty (ESG) has gained popularity over the past decade and has been adopted in both academic and private institutions globally. We present outcomes of the largest cohort of patients from the United States undergoing ESG and evaluate these according to obesity class. METHODS We performed a retrospective analysis of adult patients who underwent ESG. Medical information was abstracted from the electronic record with weight records up to 2 years after ESG. Percent total body weight loss (%TBWL) at 6, 12, 18, and 24 months was calculated based on baseline weight at the procedure. SPSS (version 29.0) was used for all statistical analyses. RESULTS A total of 1,506 patients from 7 sites were included (501 Class I obesity, 546 Class II, and 459 Class III). Baseline demographics differed according to obesity class due to differences in age, body mass index (BMI), height, sex distribution, and race. As early as 6 months post-ESG, mean BMI for each class dropped to the next lower class and remained there through 2 years. %TWBL achieved in the Class III group was significantly greater when compared with other classes at all time points. At 12 months, 83.2% and 60.9% of patients had ≥10% and ≥15% TBWL for all classes. There were no differences in adverse events between classes. DISCUSSION Real-world data from a large cohort of patients of all BMI classes across the United States shows significant and sustained weight loss with ESG. ESG is safe to perform in a higher obesity class with acceptable midterm efficacy.

Insulin resistance levels predicted metabolic improvement and weight loss after metabolic surgery in Chinese patients with type 2 diabetes. Surg Obes Relat Dis 2024; 20:80-90. [PMID: 37739868 DOI: 10.1016/j.soard.2023.08.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Revised: 07/12/2023] [Accepted: 08/05/2023] [Indexed: 09/24/2023]
Abstract
BACKGROUND The causes for failure of metabolic improvement and inadequate weight loss after metabolic surgery (MS) in Chinese patients with type 2 diabetes (T2D) have not been fully elucidated. The effect of insulin resistance (IR) on the outcome of T2D, hypertension, hyperlipidemia, and obesity after MS in Chinese patients with T2D and a body mass index (BMI) of 25-32.5 kg/m2 warrants further study. OBJECTIVES Patients with T2D and a BMI of 25-32.5 kg/m2 who underwent MS between July 2019 and June 2021 were included. SETTING University hospital, China. METHODS IR levels were evaluated with the glucose disposal rate (GDR). Improvement of T2D, hypertension, and hyperlipidemia was assessed with the composite triple endpoint (CTEP), and weight loss was assessed with the percent of total weight loss (%TWL). Partial correlation analysis, binary logistic regression analysis, multiple linear regression analysis, receiver operating characteristic curve (ROC) analysis, and subgroup analysis were used to analyze the relationship between the CTEP, %TWL at 1 year postoperative, and GDR preoperative. RESULTS This study analyzed the data of 51 patients with T2D and a BMI of 25-32.5 kg/m2 (30 men and 21 women) with a mean preoperative GDR of 3.72 ± 1.48 mg/kg/min. Partial correlation coefficients between CTEP, %TWL, and GDR were .303 (P = .041) and .449 (P = .001), respectively. The preoperative GDR was significantly positively correlated with CTEP (OR = 1.610, P = .024) and %TWL (β = 1.38, P = .003). The preoperative GDR predicted cutoff values of 4.36 and 5.35 mg/kg/min for CTEP attainment and %TWL ≥ 20%, respectively. CONCLUSION IR levels predicted metabolic improvement and weight loss 1 year after MS in Chinese patients with T2D and a BMI of 25-32.5 kg/m2.

Abstract
Background Bariatric surgery is a common procedure worldwide for the treatment of severe obesity and associated comorbid conditions but there is a lack of evidence as to medium-term safety and effectiveness outcomes in a United Kingdom setting. Objective To establish the clinical outcomes and adverse events of different bariatric surgical procedures, their impact on quality of life and the effect on comorbidities. Design Prospective observational cohort study. Setting National Health Service secondary care and private practice in Scotland, United Kingdom. Participants Adults (age >16 years) undergoing their first bariatric surgery procedure. Main outcome measures Change in weight, hospital length of stay, readmission and reoperation rate, mortality, diabetes outcomes (HbA1c, medications), quality of life, anxiety, depression. Data sources Patient-reported outcome measures, hospital records, national electronic health records (Scottish Morbidity Record 01, Scottish Care Information Diabetes, National Records Scotland, Prescription Information System). Results Between December 2013 and February 2017, 548 eligible patients were approached and 445 participants were enrolled in the study. Of those, 335 had bariatric surgery and 1 withdrew from the study. Mean age was 46.0 (9.2) years, 74.7% were female and the median body mass index was 46.4 (42.4; 52.0) kg/m2. Weight was available for 128 participants at 3 years: mean change was -19.0% (±14.1) from the operation and -24.2% (±12.8) from the start of the preoperative weight-management programme. One hundred and thirty-nine (41.4%) participants were readmitted to hospital in the same or subsequent 35 months post surgery, 18 (5.4% of the operated cohort) had a reoperation or procedure considered to be related to bariatric surgery gastrointestinal complications or revisions. Fewer than five participants (<2%) died during follow-up. HbA1c was available for 93/182 and diabetes medications for 139/182 participants who had type 2 diabetes prior to surgery; HbA1c mean change was -5.72 (±16.71) (p = 0.001) mmol/mol and 65.5% required no diabetes medications (p < 0.001) at 3 years post surgery. Physical quality of life, available for 101/335 participants, improved in the 3 years post surgery, mean change in Rand 12-item Short Form Survey physical component score 8.32 (±8.95) (p < 0.001); however, there was no change in the prevalence of anxiety or depression. Limitations Due to low numbers of bariatric surgery procedures in Scotland, recruitment was stopped before achieving the intended 2000 participants and follow-up was reduced from 10 years to 3 years. Conclusions Bariatric surgery is a safe and effective treatment for obesity. Patients in Scotland, UK, appear to be older and have higher body mass than international comparators, which may be due to the small number of procedures performed. Future work Intervention studies are required to identify the optimal pre- and post surgery pathway to maximise safety and cost-effectiveness.

Obes Surg 2023; 33:3767-3777. [PMID: 37816974 PMCID: PMC10687110 DOI: 10.1007/s11695-023-06862-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 09/16/2023] [Accepted: 09/25/2023] [Indexed: 10/12/2023]
Abstract
PURPOSE Weight loss achieved through bariatric metabolic surgery was demonstrated to be effective at reversing chronic kidney dysfunction associated with obesity-related glomerulopathy. However, robust data on how pre-operative kidney status impacts on bariatric metabolic surgery weight loss outcomes is still lacking. The aim of this study was to evaluate the impact of kidney dysfunction on weight loss outcomes after bariatric metabolic surgery. METHODS Patients with obesity to be submitted to gastric bypass surgery underwent a pre-operative evaluation of creatinine clearance, estimated glomerular filtration rate (eGFR), proteinuria, and albuminuria in 24-hour urine. Body mass index (BMI), % total weight loss (%TWL), and % excess BMI loss (%EBMIL) were assessed at 6 and 12 months after surgery. RESULTS Before surgery, patients (N=127) had a mean BMI of 39.6 ± 3.0 kg/m2, and 56.7% (n=72) had a creatinine clearance > 130 mL/min, 23.6% (n= 30) presented proteinuria > 150 mg/24h, and 15.0% (n= 19) presented albuminuria > 30 mg/24h. After surgery, the mean BMI was 27.7 kg/m2 and 25.0 kg/m2 at 6 and 12 months, respectively (p<0.0001). The %TWL was lower in patients with pre-operative eGFR < percentile 25 (34.4 ± 5.8% vs 39.4 ± 4.9%, p=0.0007, at 12 months). There were no significant correlations between weight loss metrics and pre-operative creatinine clearance rate, proteinuria, or albuminuria. CONCLUSION Early-stage chronic kidney disease (G2) has a negative impact on short-term weight loss outcomes after bariatric metabolic surgery, albeit in a magnitude inferior to the clinically relevant threshold.

Methodology and Results of a Joint IFSO-WGO Delphi Survey of 94 Intercontinental, Interdisciplinary Experts in Obesity Management. Obes Surg 2023; 33:3337-3352. [PMID: 37831326 PMCID: PMC10602939 DOI: 10.1007/s11695-023-06757-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 07/05/2023] [Accepted: 07/18/2023] [Indexed: 10/14/2023]
Abstract
BACKGROUND Obesity affects 1.5 billion people worldwide, yet few are treated effectively and considerable variability exists in its management. In 2020, a joint International Federation of Surgery for Obesity and Metabolic Diseases (IFSO) and World Gastroenterology Organization (WGO) advisory committee initiated the drafting of consensus guidelines on obesity management, to be based on detailed literature reviews and the results of an extensive multi-disciplinary survey of intercontinental experts. This paper reports on the latter. The objective of this study is to identify areas of consensus and non-consensus among intercontinental, inter-disciplinary experts in obesity management. METHODS Guided by an international consensus-survey expert, a three-round online Delphi survey was conducted in the summer of 2021 of international obesity-management experts spanning the fields of medicine, bariatric endoscopy and surgery, psychology, and nutrition. Issues like epidemiology and risk factors, patient selection for metabolic and bariatric surgery (ASMBS-Clinical-Issues-Committee, Surg Obes Relat Dis : Off J Am Soc Bariatric Surg. 8:e27-32, 1), psychological issues, patient preparation for MBS, bariatric endoscopy, and outcomes and follow-up were addressed. RESULTS Ninety-four experts from six continents voted on 180 statements, with consensus reached on 158, including consensus agreement with 96 and disagreement with 24 statements (38 had other response options besides agree/disagree). Among unanimous opinions were the need for all medical societies to work together to address obesity, for regular regional and national obesity surveillance, for multi-disciplinary management, to recognize the increasing impact of childhood and adolescent obesity, to accept some weight regain as normal after MBS, and for life-long follow-up of MBS patients. CONCLUSIONS Obesity is a major health issue that requires aggressive surveillance and thoughtful multidisciplinary management.

Analysis of Correlation between Age and Satisfied Total Weight Loss Percentage Outcome at 1 Year after Bariatric Surgery using the Restricted Cubic Spline Function: A Retrospective Study in China. Obes Surg 2023; 33:3133-3140. [PMID: 37624490 DOI: 10.1007/s11695-023-06691-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 06/12/2023] [Accepted: 06/16/2023] [Indexed: 08/26/2023]
Abstract
OBJECTIVE This study aims to explore the relationship between age and whether the percentage of total weight loss (TWL%) is ≥ 25% or not at 1 year after bariatric surgery (BS). We aimed to provide evidence for the stratified treatment of spatients with obesity at different ages. METHODS The primary outcome evaluated was whether TWL% was no less than 25% at 1 year after BS. A TWL% ≥ 25% was defined as a satisfied TWL% outcome. Logistic regression analysis and the restricted cubic spline (RCS) function were used to analyze the relationship between age and the satisfied TWL% outcome at 1 year after BS. RESULTS Two hundred and ninety-one patients were included in our study. After adjusting for potential confounders, the odds ratios (ORs) of the corresponding quartiles of age associated with satisfied TWL% outcome were 1.00 (reference), 1.117 [95% confidence interval (95% CI) = 0.540-2.311], 1.378 (95% CI = 0.647-2.935), and 0.406 (95% CI = 0.184-0.895). RCS analysis revealed a non-linear inverted L-shaped association between age and satisfied TWL% outcome at 1 year after BS (non-linear P = 0.033). CONCLUSION Age was an independent predictor of satisfied TWL% outcome one year following BS, and our study considered 32 years as a potential cut-off point. For Chinese patients over the age of 32 who are eligible for BS, it may be beneficial to do BS earlier as the probability of achieving a satisfied TWL% outcome may decrease with age.

Abstract
PURPOSE Weight loss surgery is an effective, long-term treatment for severe obesity but individual response to surgery varies widely. The purpose of this study was to test a comprehensive theoretical model of factors that may be correlated with the greatest surgical weight loss at 1-3 years following surgery. Such a model would help determine what predictive factors to measure when patients are preparing for surgery that may ensure the best weight outcomes. MATERIALS AND METHODS The Bariatric Experience Long Term (BELONG) study collected self-reported and medical record-based baseline information as correlates of 1- and 3-year % total weight loss (TWL) in n = 1341 patients. Multiple linear regression was used to determine the associations between 120 baseline variables and %TWL. RESULTS Participants were 43.4 ± 11.3 years old, Hispanic or Black (52%; n = 699), women (86%; n = 1149), and partnered (72%; n = 965) and had annual incomes of ≥ $51,000 (60%; n = 803). A total of 1006 (75%) had 3-year follow-up weight. Regression models accounted for 10.1% of the variance in %TWL at 1-year and 13.6% at 3 years. Only bariatric operation accounted for a clinically meaningful difference (~ 5%) in %TWL at 1-year. At 3 years after surgery, only bariatric operation, Black race, and BMI ≥ 50 kg/m2 were associated with clinically meaningful differences in %TWL. CONCLUSIONS Our findings combined with many others support a move away from extensive screening and selection of patients at the time of surgery to a focus on improving access to this treatment.

Abstract
Obesity is a complex, multifactorial and chronic disease. Bariatric surgery is a safe and effective treatment intervention for obesity and obesity-related diseases. However, weight loss after surgery can be highly heterogeneous and is not entirely predictable, particularly in the long-term after intervention. In this review, we present and discuss the available data on patient-related and procedure-related factors that were previously appointed as putative predictors of bariatric surgery outcomes. In addition, we present a critical appraisal of the available evidence on which factors could be taken into account when recommending and deciding which bariatric procedure to perform. Several patient-related features were identified as having a potential impact on weight loss after bariatric surgery, including age, gender, anthropometrics, obesity co-morbidities, eating behavior, genetic background, circulating biomarkers (microRNAs, metabolites and hormones), psychological and socioeconomic factors. However, none of these factors are sufficiently robust to be used as predictive factors. Overall, there is no doubt that before we long for precision medicine, there is the unmet need for a better understanding of the socio-biological drivers of weight gain, weight loss failure and weight-regain after bariatric interventions. Machine learning models targeting preoperative factors and effectiveness measurements of specific bariatric surgery interventions, would enable a more precise identification of the causal links between determinants of weight gain and weight loss. Artificial intelligence algorithms to be used in clinical practice to predict the response to bariatric surgery interventions could then be created, which would ultimately allow to move forward into precision medicine in bariatric surgery prescription.

Abstract
Context This review study aimed to investigate the definition, etiology, risk factors (RFs), management strategy, and prevention of insufficient weight loss (IWL) and weight regain (WR) following bariatric metabolic surgery (BMS). Evidence Acquisition Electronic databases were searched to retrieve relevant articles. The inclusion criteria were English articles with adult participants assessing the definition, prevalence, etiology, RFs, management strategy, and prevention of IWL/WR. Results Definition: The preferred definition for post-BMS IWL/WR are the terms "Lack of maintenance of total weight loss (TWL)>20%" and "weight change in percentage compared to nadir weight or weight loss". Prevalence: The exact prevalence of IWL/WR is still being determined due to the type of BMS and various definitions. Etiology: Several mechanisms, including hormonal/metabolic, dietary non-adherence, physical inactivity, mental health, and anatomic surgical failure, are possible etiologies of post-BMS IWL/WR. Risk factors: Preoperative body mass index (BMI), male gender, psychiatric conditions, comorbidities, age, poor diet, eating disorders, poor follow-ups, insufficient physical activity, micronutrients, and genetic-epigenetic factors are the most important RFs. Management Strategy: The basis of treatment is lifestyle interventions, including dietary, physical activity, psychological, and behavioral therapy. Pharmacotherapy can be added. In the last treatment line, different techniques of endoscopic surgery and revisional surgery can be used. Prevention: Behavioral and psychotherapeutic interventions, dietary therapy, and physical activity therapy are the essential components of prevention. Conclusions Many definitions exist for WR, less so for IWL. Etiologies and RFs are complex and multifactorial; therefore, the management and prevention strategy is multidisciplinary. Some knowledge gaps, especially for IWL, exist, and these gaps must be filled to strengthen the evidence used to guide patient counseling, selection, and improved outcomes.

Abstract
Presurgical psychopathological assessment usually focuses on detecting severe mental disorders. However, mild intensity psychopathology and eating behaviour pattern may also influence postsurgical outcomes. The aim was to identify psychopathology and eating behaviour pattern in candidates prepared for bariatric surgery compared to a normative population before and after surgery. A cohort of 32 patients seeking bariatric surgery in a university hospital between March 2016 and March 2017 were evaluated with Personality Assessment Inventory (PAI), 36-item EDE-Q and BES before and after surgery. Thirty-two patients before and 26 one year after surgery were included. The PAI presurgical psychometric profile suggested a mild mixed adjustment disorder focused on somatic complaints. After surgery, patients improved in somatic complaints (p < 0.001), and depression (p = 0.04). Related eating disorders were more common than those of the normative group and improved significantly after surgery in scores for compulsive intake (BES p < 0.001) and overall key behaviours of eating disorders and related cognitive symptoms (EDE-Q/G p < 0.001). In our cohort ready for bariatric surgery a mild psychopathological profile is still present and becomes closer to that of the normative group after surgery. Further studies are needed to evaluate the effects of mild psychopathology on outcomes after bariatric surgery.

Abstract
(1) Background: Bariatric surgery (BS) is highly effective for treating severe obesity in the long term. However, studies investigating predictors and personality profiles linked to BS success yield inconsistent results due to varying methodologies and limited research. This paper aims to identify personality profiles associated with BS success. (2) Method: The study involved 67 patients undergoing bariatric surgery, evaluated through clinical and personality measures. Weight loss was monitored at 6, 12, and 24 months post-surgery. Hierarchical case cluster analysis and iterative k-means cluster analysis identified distinct groups based on excess body mass index loss (%EBL) at these intervals. ANOVA was employed to compare personality profiles between groups. (3) Results: Average weight loss after 24 months was 67.2%. Two success profiles emerged: 46.5% showed very good success, achieving 90% EBL in 24 months, while 55% in the second cluster had less than 40% EBL throughout follow-up. The successful profile correlated with greater self-efficacy and improved emotional adjustment. (4) Conclusions: Successful BS outcomes were linked to personality traits promoting sustained weight loss post-surgery.

Abstract
BACKGROUND Attachment avoidance and anxiety have been linked to overweight and poor health behaviours, yet the mechanisms that underpin the relationship between attachment and health behaviours are not fully understood. Self-esteem and self-efficacy have been found to differ between attachment styles, rendering these variables potential mediators of the relationship. This longitudinal study investigated the serial mediation between preoperative attachment and 2-year post-operative health behaviours through self-esteem and health self-efficacy. METHODS Participants were 263 bariatric surgery patients (75.7% females, aged 47.7 ± 10.4 years, BMI 38.9 ± 3.6 kg/m2) assessed before the operation and again one and two years after the surgery. Patients completed the Experiences for Close Relationships Brief Scale, Rosenberg Self-esteem scale, Weight Efficacy Lifestyle Questionnaire, Bariatric Surgery Self-Management Questionnaire, Exercise Self-Efficacy Scale and the Exercise Behaviour Scale. RESULTS Higher preoperative attachment anxiety and avoidance were associated with lower self-esteem one year after bariatric surgery and poorer health self-efficacy two years after the surgery. Self-esteem and health self-efficacy mediated the relationships between preoperative anxious and avoidant attachment and 2- year post-operative diet adherence and physical activity. CONCLUSIONS Helping patients to feel more worthy and reinforcing their beliefs about their own competences could lead to higher engagement with healthy lifestyle and adherence to treatment protocols, ultimately helping patients to achieve their goals for bariatric surgery.

Outcomes at 10-Year Follow-Up after Roux-en-Y Gastric Bypass, Biliopancreatic Diversion, and Sleeve Gastrectomy. J Clin Med 2023; 12:4973. [PMID: 37568375 PMCID: PMC10419540 DOI: 10.3390/jcm12154973] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 07/04/2023] [Accepted: 07/19/2023] [Indexed: 08/13/2023] Open
Abstract
INTRODUCTION Morbid obesity is a well-defined chronic disease, the incidence of which is constantly rising. Surgical treatment of morbid obesity has produced superior outcomes compared to conventional weight loss measures. Currently, there is a gap in the literature regarding long-term outcomes. Our single-institution, retrospective cohort study aims to evaluate weight loss outcomes, comorbidity reduction, and adverse effects at 10 years following Roux-en-Y Gastric Bypass (RYGB), Biliopancreatic Diversion (BPD), and Sleeve Gastrectomy (SG). MATERIALS AND METHODS We included all consecutive patients with 10-year follow-up records operated on within our institution. The comparison was carried out on the average percentage of weight and BMI loss. Nausea and vomiting were evaluated through self-reporting Likert scales. Diabetes resolution and nutritional deficiencies were also evaluated. RESULTS A total of 490 patients from 1995 up to 2011 were included in our study. Of these, 322 underwent RYGB, 58 underwent long-limb BPD, 34 underwent laparoscopic RYGB with fundus excision, 47 underwent laparoscopic SG, and 29 underwent laparoscopic RYGB as a revision of prior SG. RYGB and BPD were significantly associated with higher percentages of weight loss (37.6% and 37.5%), but were not found to be independent predictors of weight loss. Nausea and vomiting were associated with SG and laparoscopic RYGB with fundus excision, more so than the other operations. No differences were observed regarding diabetes resolution and nutritional deficiencies. CONCLUSIONS Longer follow-up reports are important for the comparison of outcomes between different types of bariatric operations. BPD and RYGB resulted in superior weight loss, with no observed differences in diabetes resolution and adverse outcomes.

Abstract
BACKGROUND Conflicting results have been reported regarding the predictive value of preoperative psychological assessment and weight outcome after bariatric surgery. This might be attributed to different factors affecting early weight loss and long-term weight loss. Herein, we investigated whether preoperative psychiatric profile was associated with preoperative BMI and with both early (1 year) and long-term (5 years) weight loss after Roux-en-Y gastric bypass (RYGB). METHODS Prospective observational cohort study of patients undergoing RYGB between 2013 and 2019. Symptoms related to anxiety, depression, eating disorder, and alcohol use disorders were assessed by employing validated, specific psychometric tests (STAI-S/T, BDI-II, BITE, AUDIT-C) prior to surgery. Pre-operative BMI, early weight loss (1 year), and long-term weight evolution (up to 5 years) were registered. RESULTS Two hundred thirty six patients (81% women) were included in the present study. Linear longitudinal mixed model showed a significant effect of preoperative high anxiety (STAI-S) on long-term weight outcome, after controlling for gender, age and type 2 diabetes. Patient with high preoperative anxiety score regained weight faster than those experiencing low anxiety (each year percent excess BMI loss (%EBMIL) - 4.02%, ± 1.72, p = 0.021). No other pre-operative psychiatric symptoms have been shown to have an impact on long-term weight loss. In addition, no significant association was found between any of the pre-operative psychiatric variables and pre-operative BMI, or early weight loss (%EBMIL) at 1-year post-RYGB. CONCLUSION Herein we identified high anxiety score (STAI-S) as a predictor for long-term weight regain. Thus, long-term psychiatric surveillance of these patients and the development of tailored management tools could serve as a means to prevent weight regain.

Obes Surg 2023; 33:2040-2048. [PMID: 37129789 DOI: 10.1007/s11695-023-06586-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 04/05/2023] [Accepted: 04/05/2023] [Indexed: 05/03/2023]
Abstract
INTRODUCTION There is a need for a standardized, evidence-based classification of post-bariatric weight-regain, to investigate and compare revision procedures and to advice and treat patients in an evidence-based way. METHODS We used standard deviations (SD) of the highest (1-2 years) and latest (> 2 years) percentage total weight loss (%TWL) results after primary bariatric surgery from the Dutch Audit for Treatment of Obesity (DATO) bariatric registry as benchmarks for (above) average (≥ - 1SD), poor (- 1SD to - 2SD) and insufficient (< - 2SD) weight loss. Weight regain maintaining (above) average weight loss was called grade 1, weight regain towards poor weight loss grade 2, towards insufficient weight loss grade 3, with subgrades 2a/3a for below average weight loss from the start, and 2b/3b for weight regain from (above) average to below average weight loss. Patient characteristics and diabetes improvement/impairment were compared. Sensitivity and specificity of 14 existing weight regain criteria were calculated. RESULTS We analyzed 93,465 results from 38,830 patients (77.1% gastric bypass, 22.5% sleeve gastrectomy). The - 1SD thresholds for early and late weight loss approximated 25%TWL and 20%TWL, the - 2SD threshold for late weight loss 10%TWL. Weight regain could be analyzed for 18,403 patients (2.5-5.2 years follow-up). They regained mean 6.7 kg (5.4%TWL), with 66.8% grade 1 weight regain, 7.2% grade 2a, 7.4% grade 2b, 2.1% grade 3a, and 0.6% grade 3b. There were significant differences in comorbidities, gender, age, weight regain, diabetes impairment, and diabetes improvement across grades. Weight regain criteria from literature were extremely divers. None had high sensitivity. CONCLUSION The DATO classification for post-bariatric weight regain combines the extent of weight regain with evidence-based endpoints of weight loss. It differentiated weight regain maintaining (above) average weight loss, two intermediate grades, gradual weight regain with below average weight loss from the start (primary non-response) and steep weight regain towards insufficient weight loss (secondary non-response). The classification is superior to existing criteria and well supported by evidence.

Abstract
Bariatric surgery is the most effective treatment for sustained weight reduction, and it can result in substantial improvements in the severity of type 2 diabetes, metabolic syndrome, nonalcoholic fatty liver disease, and quality of life. However, sleeve gastrectomy, a weight loss surgery that removes two-thirds of the stomach, reduces appetite and nutrient absorption, impairing digestion and the absorption of nutrients like iron, vitamin B12, and protein-bound nutrients. This case study aims to demonstrate that patients undergoing sleeve gastrectomy require long-term and periodic monitoring of biochemical data, weight changes, and caloric and protein intake by a professional nutritionist to prevent malnutrition and nutritional deficiencies. In this case study, a 48-year-old woman was diagnosed with morbid obesity, hypertension, sleep apnea syndrome, and chronic gastritis. At initial evaluation, she was 160 cm tall and weighed 89 kg, with a body mass index of 34.8 kg/m2. At 1 postoperative year, she consumed 650 kcal and 25 g of protein per day, the percentage of excess weight loss was 141.1%, and body mass index was 21 kg/m2. Compared to preoperative levels, calcium and folic acid levels did not decrease after 1 postoperative year, but hemoglobin, ferritin, and vitamin B12 levels decreased. In conclusion, when patients experience rapid weight loss after sleeve gastrectomy, follow-up should be frequent and long. Dietary education should be conducted according to digestive symptoms, and oral nutritional supplements, including vitamins and minerals.

Abstract
PURPOSE Subjects with obesity, especially those seeking bariatric surgery, exhibit high rates of mental disorders and marked psychopathological traits. The primary objective of this prospective, non-interventional study was to investigate whether the presence of different psychiatric disorders, attention deficit/hyperactivity disorder (ADHD) symptomatology and emotional dysregulation influenced weight loss at 1-year follow-up after surgery. METHODS Subjects consecutively referred for pre-surgical evaluation at the Obesity Center of Pisa University Hospital were recruited. Psychiatric diagnoses were made through the Mini-International Neuropsychiatric Interview (MINI) and ADHD symptomatology was assessed with the Wender-Reimherr Adult Attention Deficit Disorder Scale (WRAADDS). Emotional dysregulation was investigated through the WRAADDS and self-report questionnaires. After surgery, weight and obesity-related comorbidities were monitored during follow-up. RESULTS Of the 99 participants recruited, 76 underwent surgery and 65 could be reevaluated 1 year after surgery. Subjects with insufficient weight loss (excess body mass index loss ≤ 53%, n = 15) had more frequent lifetime binge eating disorder (BED) and BED-mood disorders comorbidity than subjects with favorable post-surgical outcome. Additionally, they scored higher on both physician-administered and self-report scales assessing emotional dysregulation, which represents a nuclear symptom of ADHD in adults. At the logistic regression analysis, older age, higher preoperative excess body mass index and greater affective instability were predictors of reduced weight loss at 1-year follow-up. CONCLUSION Emotional dysregulation seems to be associated with a worse outcome after bariatric surgery. Further studies with larger samples and longer follow-up are needed to confirm the influence of different psychiatric disorders and psychopathological traits on post-surgical outcome. LEVEL OF EVIDENCE V, prospective descriptive study.

Abstract
PURPOSE to determine the risks and benefits of bariatric surgery in patients with super obesity (SO) in comparison with obesity grades II and III. METHODS retrospective cohort that included a study group of 178 patients with SO and a control group of 181 patients with BMI 35-49.9Kg/m2. The groups were formed in a 1:1 nearest neighbor matching. The main variables were pre- and postoperative BMI and comorbidities, occurrence of severe postoperative complications, bowel obstruction, marginal ulcer, fistulae and 30-day death, besides the necessity of emergency room (ER) admission and abdominal computed tomography (CT) scans in the postoperative period due to acute abdomen. RESULTS the study group comprised 74.0% of women while the control group had 56.7%. The mean follow-up time was similar between both groups (5.48 x 6.09 years, p=0.216). There was no statistically significant difference on the prevalence of hypertension and T2D between the groups according to the surgical technique. All deaths occurred in the Study group (BMI = 50kg/m2) who underwent RYGB. There was no difference between the groups regarding the occurrence of severe complications. Data on ER admissions and the need for abdominal CT to investigate postoperative abdominal pain did not show statistically significant difference between the groups. CONCLUSION despite the high risk related to bariatric surgery in patients with SO, the benefits related to the remission of comorbidities are significant; although being lower than those found in patients with milder grades of obesity.

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
INTRODUCTION Identifying eating behaviors associated with suboptimal weight loss following bariatric surgery remains important. This study assessed the relationship between eating behaviors and weight loss following bariatric surgery in a racially diverse sample. METHODS Participants were assessed before surgery and 6 and 12 months postoperatively, with the Structured Clinical Interview for DSM-5, the Eating Disorder Examination-Bariatric Surgery Version, and validated measures assessing a range of eating behaviors. Linear mixed effect models were used to test the impact of eating behaviors on percent weight loss (%WL) at 6 and 12 months. RESULTS We enrolled 300 participants (mean age 40.1 years; BMI 45.9 kg/m2; 87% women; 62% Black and 30% White). The majority (82%) underwent sleeve gastrectomy (SG). Mean %WL was 23.0 ± 5.1% at 6 months and 26.2 ± 7.6% at 12 months. Subjective binge episodes prior to surgery predicted greater %WL over the first 12 postoperative months (p = 0.028). Postoperative disinhibition, hunger, night eating symptoms, objective binge episodes, global disordered eating attitudes and behaviors, and snacks per day were associated with smaller %WL over 12 months (all p's < 0.01). The presence of picking/nibbling and addictive-like eating behaviors was not associated with %WL at the end of the first postoperative year. CONCLUSION Among a diverse participant sample, problematic eating behaviors following surgery were associated with smaller %WL over 12 months. Postoperative assessment and treatment of eating behaviors are needed to address these issues as they arise and to prevent attenuation of early weight loss in some patients.

Abstract
Although bariatric surgery results in a significant weight reduction and an improvement in the quality of life in most people who undergo surgery, there are inter-individual differences in terms of postoperative results. Psychological, psychiatric and addictive disorders contribute substantially to these difficulties. Between 20% and 50% of bariatric surgery candidates have a current psychiatric/addictive disorder and approximately 30-75% have a history of a psychiatric/addictive disorder within their lifetime. Surgery is accompanied in the short-term by an improvement in depressive symptoms and binge eating, but these symptoms tend to increase again beyond the 3rd postoperative year. Over the long-term, only the improvement in depression remains durable, whilepostoperative anxiety and disordered eating symptoms do not differ significantly from the preoperative levels. There is a two to four fold increased risk of post-surgical suicide and suicide attempts (from the 1st postoperative year onward), as well as an increased risk of alcohol-abuse (beyond two years after surgery). Psychological support must therefore continue long-term. Several psychotherapeutic and pharmacological treatments have demonstrated their effectiveness in improving the postoperative prognosis of patients with psychological/psychiatric disorders. The early integration of psychological/psychiatric/addiction evaluation and support into multidisciplinary management makes it easier to identify these difficulties and to optimize the postoperative prognosis, both in terms of weight and quality of life. Prior to surgery, patients should be systematically evaluated by a psychologist or psychiatrist in order to identify and to manage disorders that could negatively impact the postoperative prognosis. After surgery, this assessment and support can be carried out in a programmed and systematic way for those patients who were identified preoperatively as the most vulnerable, but support can also be offered during follow-up in the event of specific symptoms (i.e., loss of control over food intake, failure in terms of weight or quality of life, suicidal ideation, loss of control over alcohol use, significant depression or anxiety symptoms).

Comparison of hypertension remission and relapse after sleeve gastrectomy and one-anastomosis gastric bypass: a prospective cohort study. Hypertens Res 2023; 46:1287-1296. [PMID: 36670229 DOI: 10.1038/s41440-023-01180-7] [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: 09/11/2022] [Revised: 11/27/2022] [Accepted: 12/28/2022] [Indexed: 01/21/2023]
Abstract
This study aimed to assess the remission and relapse of hypertension (HTN) in hypertensive individuals who underwent sleeve gastrectomy (SG) and one-anastomosis gastric bypass (OAGB) and identify the predictors of HTN remission and relapse following bariatric surgery. A prospective cohort study with a follow-up of 3 years was conducted on severely obese patients between 2013 and 2018. Hypertension remission was defined as the normalization of blood pressure (BP) with the discontinuation of medical treatment, and HTN relapse was defined as the need for the onset of antihypertensive drugs or the occurrence of BP impairment. A total of 787 hypertensive patients were included in this study. The cumulative incidence of HTN remission and relapse were 83.9% (95% CI: 81.6-86.5) and 31.4% (95% CI: 25.6-38.2), respectively. Remission and relapse were not significantly different among the patients undergoing either surgery (SG or OAGB). A higher remission rate was linked to a younger age and the use of fewer antihypertensive medications pre-operation. However, failure to successfully lose weight during the first year postoperative and weight regain predicted a higher risk of HTN relapse after 3 years. Following bariatric surgery, BP drops initially but then gradually rises. These alterations are responsible for about 31% relapse after 3 years in those who initially achieve remission. Patients who are younger and use less antihypertensive medications before surgery may benefit the most from bariatric surgery in terms of HTN. First-year successful weight loss and control of weight regain may prevent HTN relapse in the following years.

Abstract
BACKGROUND Metabolic and bariatric surgery (MBS) has been established to provide long-term weight loss in severe obesity. In this study, we investigated the factors that affect post-operative weight loss, with a particular focus on changes in eating behaviors. METHODS Time-course changes in body weight and eating behaviors were examined in 49 Japanese patients who underwent laparoscopic sleeve gastrectomy from the first visit to 12 months after surgery. Each eating behavior was evaluated via the questionnaire of the Japan Society for the Study of Obesity. RESULTS Pre-operative weight reduction mediated by dietary and lifestyle interventions showed significant positive correlations with weight loss outcomes at 12 months after surgery. We observed significant decreases in scores for most of the eating behaviors 12 months after surgery. However, "emotional eating behavior" scores declined temporarily in the early post-operative period of one month but thereafter returned to the pre-operative level at 12 months. Furthermore, increases in the scores for "emotional eating behavior" and "sense of hunger" from 1 to 12 months post-operatively were significantly associated with poor weight loss. CONCLUSIONS Our results demonstrate the beneficial effects of MBS on obesity-related eating behaviors, as well as highlighting "emotional eating behavior" as requiring particular attention.

Abstract
BACKGROUND Many studies have reported that bariatric surgery may reduce postoperative cardiovascular risk in patient with obesity, but few have addressed this risk in the Chinese population. OBJECTIVE To assess the impact of bariatric surgery on cardiovascular disease (CVD) risk in the Chinese population using the World Health Organization (WHO) risk model, the Global risk model, and the Framingham Risk Score. METHODS We retrospectively analyzed data collected on patient with obesity who underwent bariatric surgery at our institution between March 2009 and January 2021. Their demographic characteristics, anthropometric variables, and glucolipid metabolic parameters were assessed preoperatively and at their 1-year postoperative follow-up. Subgroup analysis compared body mass index (BMI) < 35 kg/m2 and BMI ≥ 35 kg/m2, as well as gender. We used the 3 models to calculate their CVD risk. RESULTS We evaluated 61 patients, of whom 26 (42.62%) had undergone sleeve gastrectomy (SG) surgery and 35 (57.38%) Roux-en-Y gastric bypass (RYGB) surgery. Of the patients with BMI ≥ 35 kg/m2, 66.67% underwent SG, while 72.97% with BMI < 35 kg/m2 underwent RYGB. HDL levels were significantly higher at 12 months postoperatively relative to baseline. When the models were applied to calculate CVD risk in Chinese patients with obesity, the 1-year CVD risk after surgery were reduced lot compared with the preoperative period. CONCLUSION Patient with obesity had significantly lower CVD risks after bariatric surgery. This study also demonstrates that the models are reliable clinical tools for assessing the impact of bariatric surgery on CVD risk in the Chinese population.

Abstract
OBJECTIVE This case-control study aimed to analyze the dynamics of macrophage infiltration in subcutaneous adipose tissue following bariatric surgery or conservative treatment of obesity and to clarify whether these features predict the weight loss outcome after the surgery. METHODS Subcutaneous tissue samples taken before and 12 months after laparoscopic Roux-en-Y gastric bypass surgery (n = 39) or conservative (n = 43) treatment for obesity were analyzed. Fat cell size was determined, and with CD68 immunohistochemistry, crown-like structures (CLS) were counted and single macrophages were quantitated. RESULTS A major decline in CLS density from 4.1 (SD 3.5) to 1.1 (SD 0.8) per 1000 fat cells (p < 0.000) was found, regardless of the degree of weight loss after the surgery. Surgery had no effect on the fraction of infiltrating single-cell macrophages in subcutaneous adipose tissue. The abundance of these macrophage populations before the intervention did not predict the degree of postsurgery weight loss or suboptimal response to the surgery. CONCLUSIONS The effect of gastric bypass on adipose tissue inflammatory status associates closely with CLS density even in subjects with suboptimal weight loss. The study suggests that factors related to bypass surgery other than weight loss modify the inflammatory response in adipose tissue.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) surgery is an established, effective treatment for severe adolescent obesity. Long-term dietary intake and the relationship to eating-related problems are scarcely evaluated in this population. OBJECTIVES Assess changes in dietary intake in adolescents after RYGB and explore associations between dietary intake and eating-related problems. SETTING Multicenter study in Swedish university hospitals. METHOD Diet history, binge eating scale (BES), and Three-Factor Eating Questionnaire were assessed preoperatively and 1, 2, and 5 years after RYGB in 85 adolescents (67% female) aged 16.5 ± 1.2 years with a body mass index (BMI) of 45.5 ± 6.0 kg/m2 and compared with control individuals at 5 years. RESULTS Five-year BMI change was -28.6% ± 12.7% versus +9.9% ± 18.9% in RYGB patients versus control individuals (P < .001). Through 5 years, RYGB adolescents reported reduced energy intake, portion size of cooked meals at dinner, and milk/yoghurt consumption (P < .01). The BES scores were 9.3 ± 8.3 versus 13.4 ± 10.5 in RYGB patients versus control individuals (P = .04). Association between BES score and energy intake was stronger in control individuals (r = .27 versus r = .62 in RYGB patients versus control individuals, P < .001). At 5 years, lower energy intake was associated with greater BMI loss in all adolescents (r = .33, P < .001). Higher scores in BES and uncontrolled and emotional eating were associated with higher energy intake, cooked meals, candies/chocolates, cakes/cookies, desserts, and sugary drinks (r > .23, P < .04) and lower intake of fruits/berries (r = -.32, P = .044). A higher score in cognitive restraint was associated with a higher intake of cereals and fruits/berries (r > .22, P < .05) and a lower intake of sugary drinks (r = -.24, P < .03). CONCLUSION To support optimization of long-term outcomes in adolescent RYGB patients, it is important to provide management strategies to reduce energy intake. Monitoring eating-related problems could identify potential individuals at risk of poor weight loss and to initiate treatment interventions.

Abstract
Type 2 diabetes mellitus is a complex and under-treated disorder closely intertwined with obesity. Adolescents with severe obesity and type 2 diabetes have a more aggressive disease compared to adults, with a rapid decline in pancreatic β cell function and increased incidence of comorbidities. Given the relative paucity of pharmacotherapies, bariatric surgery has become increasingly used as a therapeutic option. However, subsets of this population have sub-optimal outcomes with either inadequate weight loss or little improvement in disease. Predicting which patients will benefit from surgery is a difficult task and detailed physiological characteristics of patients who do not respond to treatment are generally unknown. Identifying physiological predictors of surgical response therefore has the potential to reveal both novel phenotypes of disease as well as therapeutic targets. We leverage data assimilation paired with mechanistic models of glucose metabolism to estimate pre-operative physiological states of bariatric surgery patients, thereby identifying latent phenotypes of impaired glucose metabolism. Specifically, maximal insulin secretion capacity, σ, and insulin sensitivity, SI, differentiate aberrations in glucose metabolism underlying an individual's disease. Using multivariable logistic regression, we combine clinical data with data assimilation to predict post-operative glycemic outcomes at 12 months. Models using data assimilation sans insulin had comparable performance to models using oral glucose tolerance test glucose and insulin. Our best performing models used data assimilation and had an area under the receiver operating characteristic curve of 0.77 (95% confidence interval 0.7665, 0.7734) and mean average precision of 0.6258 (0.6206, 0.6311). We show that data assimilation extracts knowledge from mechanistic models of glucose metabolism to infer future glycemic states from limited clinical data. This method can provide a pathway to predict long-term, post-surgical glycemic states by estimating the contributions of insulin resistance and limitations of insulin secretion to pre-operative glucose metabolism.

Abstract
Obesity is a well-established risk factor for increased morbidity and mortality. Comprehensive lifestyle interventions, pharmacotherapy, and bariatric surgery are three effective treatment approaches for obesity. The Veterans Health Administration (VHA) offers all three domains but in different configurations across medical facilities. Study aim was to explore the relationship between configurations of three types of obesity treatments, context, and population impact across VHA using coincidence analysis. This was a cross-sectional analysis of survey data describing weight management treatment components linked with administrative data to compute population impact for each facility. Coincidence analysis was used to identify combinations of treatment components that led to higher population impact. Facilities with higher impact were in the top two quintiles for (1) reach to eligible patients and (2) weight outcomes. Sixty-nine facilities were included in the analyses. The final model explained 88% (29/33) of the higher-impact facilities with 91% consistency (29/32) and was comprised of five distinct pathways. Each of the five pathways depended on facility complexity-level plus factors from one or more of the three domains of weight management: comprehensive lifestyle interventions, pharmacotherapy, and/or bariatric surgery. Three pathways include components from multiple treatment domains. Combinations of conditions formed "recipes" that lead to higher population impact. Our coincidence analyses highlighted both the importance of local context and how combinations of specific conditions consistently and uniquely distinguished higher impact facilities from lower impact facilities for weight management.

Predicting Early Weight Loss Failure Using a Bariatric Surgery Outcomes Calculator and Weight Loss Curves. Obes Surg 2022; 32:3932-3941. [PMID: 36253661 DOI: 10.1007/s11695-022-06294-4] [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: 03/31/2022] [Revised: 09/23/2022] [Accepted: 09/28/2022] [Indexed: 11/24/2022]
Abstract
CONTEXT Weight loss after bariatric surgery can be accurately predicted using an outcomes calculator; however, outliers exist that do not meet the 1 year post-surgery weight projections. OBJECTIVE Our goal was to determine how soon after surgery these outliers can be identified. DESIGN We conducted a retrospective cohort study. SETTING, PATIENTS, AND INTERVENTION Using a bariatric surgery outcomes calculator formulated by the Michigan Bariatric Surgery Collaborative (MBSC), predicted weight loss at 1 year post-surgery was calculated on all patients who underwent primary bariatric surgery at a single-center academic institution between 2006 and 2015 who also had a documented 1-year follow-up weight (n = 1050). MAIN OUTCOME MEASURES Weight loss curves were compared between high, low, and non-outliers as defined by their observed-to-expected (O:E) weight loss ratio based on total body weight loss (TBWL) %. RESULTS Mean predicted weight loss for the study group was 39.1 ± 9.9 kg, while mean actual weight loss was 39.7 ± 17.1 kg resulting in a mean O:E 1.01 (± 0.35). Based on analysis of the O:E ratios at 1 year post-surgery, the study group was sub-classified. Low outliers (n = 188, O:E 0.51) had significantly lower weight loss at 2 months (13.1% vs 15.6% and 16.5% TBWL, p < 0. 001) and at 6 months (19% vs 26% and 30% TBWL, p < 0.001) when compared to non-outliers (n = 638, O:E 1.00) and high outliers (n = 224, O:E 1.46), respectively. CONCLUSIONS Weight loss curves based on individually calculated outcomes can help identify low outliers for additional interventions as early as 2 months after bariatric surgery.

The Factor Structure and Stability of the Beck Depression Inventory-II (BDI-II) in a Population Undergoing Bariatric Surgery. Obes Surg 2022; 32:3732-3739.

Abstract
PURPOSE Depression is a multifaceted psychiatric condition that has been associated with suboptimal weight loss following bariatric surgery. Previous variations of Beck Depression Inventory-Second Edition (BDI-II) subscales been proposed, including those identified within bariatric populations; however, it is unclear whether the BDI-II items contained within these subscales would remain consistent after the procedure considering the physical and lifestyle changes that occur following bariatric surgery. MATERIALS AND METHODS A two-step analytic approach that comprised of exploratory (EFA) and confirmatory factor analyses (CFA) that aimed to identify a stable factor structure using pre- and 6-month post-surgical BDI-II responses. Baseline BDI-II responses of 149 patients (Group 1) were used to identify an initial EFA model. Five BDI-II models underwent CFA using BDI-II responses of a comparable pre-surgical group (Group 2; n = 142), and 6-month post-surgical data from Group 1. RESULTS EFA generated a two-factor solution. Of the five CFA models performed, the three-factor model that was initially identified by Hayes (2015) among patients undergoing bariatric surgery demonstrated superior fit across time and between groups. CONCLUSIONS Although the EFA initially identified a two-factor model, CFA determined that a previously defined three-factor model reliably fit both pre- and post-surgical BDI-II responses. This study supports using the Hayes (2015) subscales when monitoring pre- and post-bariatric surgery facets of depression specific to this population. Being able to accurately and reliably monitor depressive symptoms of patients that are undergoing bariatric surgery will allow for the provision and monitoring of targeted interventions aimed at improving their mental and physical health outcomes.

Abstract
INTRODUCTION Obesity is a chronic disease with a complex interplay of multiple factors such as genetic, metabolic, behavioral, and environmental factors. The management of obesity includes; lifestyle modification, psychological therapy, pharmacological therapy, and bariatric surgery. To date, bariatric surgery is the most effective treatment for obesity by offering a long-term reduction in weight, remission of obesity-related complications, and improving quality of life. However, bariatric surgery is not equally effective in all patients. Thus, if we can predict who would benefit most, it will improve the risk versus benefit ratio of having surgery. AREAS COVERED In this narrative review, we explore the question on who will benefit the most from bariatric surgery by examining the recent evidence in the literature. In addition, we investigate the predisposing predictors of bariatric surgery response. Finally, we offer the best strategies in the clinic to explain the potential benefits of bariatric surgery to patients. EXPERT OPINION Bariatric surgery is an effective obesity management approach. Despite its efficacy, considerable variation of individual response exists. Thus, it is important to recognize patients that will benefit most, but at present very few predictors are available which can be clinically useful.

Abstract
Attentional bias (AB) to food after bariatric surgery might be a cognitive marker for weight regain. The visual probe task (VPT) is commonly used to capture AB at automatic, pre-conscious, and conscious orientation of attention. The aim of this study was to investigate how the preoperative BMI of patients submitted to Roux-en-Y gastric bypass (RYGB) impacts AB to food. We assessed patients who had preoperative BMI>50 (n = 28) or preoperative BMI<50 (n = 31) months after the RYGB procedure. Participants underwent clinical, psychological, and VPT evaluations. In VPT, pairs of food and matching non-food images were shown for 100 ms, 500 ms or 2000 ms and AB for food was assessed for each exposure time. A significant AB to food was observed at 2000 ms for all patients in this study, suggesting that the overall sample were consciously orienting their attention toward food cues after surgery, a finding that might be relevant for understanding weight control. When groups with preoperative BMI higher and lower than 50 kg/m2 were compared, a significant difference on AB to food stimuli at 500 ms was observed, controlling for excess weight lost since surgery and postoperative time. Subjects with preoperative BMI>50 had a positive and reliable AB to food while subjects with preoperative BMI<50 had a negative AB. This suggests that food stimuli have a higher incentive salience even after surgery for those with BMI>50, which might explain why subjects with higher preoperative weight have higher risks for weight regain. These results may indicate that RYGB can impact incentive salience for food cues in a differential manner, increasing conscious AB in all patients and decreasing pre-conscious AB only in those with BMI<50 kg/m2.

Abstract
Obesity is a worldwide disease associated with multiple severe adverse consequences and comorbid conditions. While an increased body weight is the defining feature in obesity, etiologies, clinical phenotypes and treatment responses vary between patients. These variations can be observed within individual treatment options which comprise lifestyle interventions, pharmacological treatment, and bariatric surgery. Bariatric surgery can be regarded as the most effective treatment method. However, long-term weight regain is comparably frequent even for this treatment and its application is not without risk. A prognostic tool that would help predict the effectivity of the individual treatment methods in the long term would be essential in a personalized medicine approach. In line with this objective, an increasing number of studies have combined neuroimaging and computational modeling to predict treatment outcome in obesity. In our review, we begin by outlining the central nervous mechanisms measured with neuroimaging in these studies. The mechanisms are primarily related to reward-processing and include "incentive salience" and psychobehavioral control. We then present the diverse neuroimaging methods and computational prediction techniques applied. The studies included in this review provide consistent support for the importance of incentive salience and psychobehavioral control for treatment outcome in obesity. Nevertheless, further studies comprising larger sample sizes and rigorous validation processes are necessary to answer the question of whether or not the approach is sufficiently accurate for clinical real-world application.

Higher Preoperative Weight loss Is Associated with Greater Weight Loss up to 12 Months After Bariatric Surgery. Obes Surg 2022; 32:2860-2868. [PMID: 35788954 DOI: 10.1007/s11695-022-06176-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2022] [Revised: 06/18/2022] [Accepted: 06/22/2022] [Indexed: 10/17/2022]
Abstract
BACKGROUND Prior research suggested presurgical weight loss is associated with greater total weight loss, resulting in a more effective bariatric intervention. We aimed to assess whether preoperative weight loss is a predictor for total weight loss, and which patient factors are associated with successful weight loss. METHODS All patients (N = 773) that underwent primary bariatric surgery between June 2017 and August 2019 were included in this single-center retrospective study. Outcome measures were preoperative weight loss (%preopWL) and total weight loss (%TWL) up to 1 year postoperatively. Patients were divided into 4 groups based on quartiles of %preopWL. RESULTS Total weight loss after 1, 6, and 12 months for the upper quartile was 16.9%, 33.4%, and 37.8%, and for the lower quartile 11.8%, 28.9%, and 35.2%, respectively (p < 0.001). Seven hundred fourteen patients (92.4%) were available for the 1-year follow-up. Preoperative weight loss was not associated with the incidence of complications. Independent factors predicting increased %preopWL were mandated preoperative weight loss program (MWP) (p < 0.001), older age (p = 0.005), weight measurement in the week before surgery (p = 0.031), and non-diabetic status (p = 0.010). Predictors for superior %TWL were MWP (p = 0.014), younger age (p = 0.001), non-diabetic status (p = 0.005), female gender (p = 0.001), higher Body Mass Index (p = 0.006), and banded gastric bypass (p = 0.001). CONCLUSION Higher preoperative weight loss is associated with persisting greater weight loss up to at least 12 months post-surgery. In order to optimize preoperative weight loss, we recommend extra preoperative support to younger and diabetic patients. We advise nutritional counseling and additional weight measurement in the week before surgery.

Abstract
Bariatric surgery (BS) is the most effective treatment strategy for obesity. Nevertheless, a subset of patients does not reach a successful weight loss or experience long-term weight regain. Conflicting evidence exists regarding predictors of BS outcomes. We aimed to define the early factors linked to 3 year unsuccessful weight loss in order to promote a tailored close follow-up. We enrolled 443 patients who underwent BS from January 2014 to December 2018 with a 3 year follow-up. An unsuccessful BS outcome was defined as a percentage of total weight loss (%TWL) < 20. We compared the characteristics between successful and unsuccessful patients in order to identify predictor factors of unsuccess after surgery. We found that the proportion of patients with unsuccessful weight loss progressively increased from one to three years after BS. In a multiple regression model, only 1 month %TWL and sleeve gastrectomy (SG) were significantly associated with 3 year unsuccessful weight loss. We stratified our cohort in four groups according to the risk of BS unsuccess, in terms of 1 month %TWL and type of surgery (SG vs gastric bypass). Interestingly, groups showed a significant difference in terms of %TWL at each follow-up point. Patients submitted to SG with lower 1 month %TWL must be considered at higher risk of future weight regain; consequently, they require a tailored and closer follow-up.
