Abstract
BACKGROUND It might not be possible to achieve the desired outcome in every patient following bariatric surgery, even though every patient is thoroughly examined before surgery. This study aimed to develop a regression model based on parameters that affect weight loss success in patients scheduled for laparoscopic sleeve gastrectomy (LSG) and thus preoperatively predict whether the patients will have an optimal clinical response in terms of weight loss at the end of the first year. MATERIALS AND METHODS Between January 2018 and August 2022, patients who underwent LSG were analyzed retrospectively. Age, sex, comorbidities, smoking status, alcohol use status, preoperative weight, preoperative body mass index (BMI), preoperative laboratory data, weight, and total weight loss (TWL)% values at the end of the first year were recorded. At the end of the first year following LSG, patients with TWL% above 20% were defined as having an optimal clinical response in terms of weight loss. This study is designed, conducted, and reported regarding the "transparent reporting of a multivariable prediction model for individual prognosis or diagnosis" (TRIPOD) statement. The final model was used to construct an Excel-based calculator. RESULTS Four hundred thirty-eight patients underwent the sleeve gastrectomy procedure, and 38 of them were excluded from the study because of a lack of 1-year follow-up information, resulting in 400 eligible patients for our study. Age, glucose, thyroid stimulating hormone (TSH), alcohol consumption, systemic immune inflammation index (SII), and tobacco were the independent predictors of optimal clinical response ( P <0.001, P <0.001, P <0.001, P =0.011, P =0.039, P =0.045, respectively). The model was called the GAASThyriC score. When the final model was tested in the validation cohort, the AUC was 0.875 (95% CI, 0.742-0.999), the sensitivity was 83.3% (95% CI, 51.6-97.9), specificity was 86.4% (95% CI, 77.4-92.8), negative likelihood ratio was 0.19 (95% CI, 0.05-0.68), and accuracy was 86% (95% CI, 77.6-92.1) when the cutoff value was set to the optimal threshold (logit = 0.8451). CONCLUSION The GAASThyriC score can be used as an effective auxiliary tool to predict the patient population with suboptimal clinical response in terms of TWL% at the end of the first year after LSG.

Abstract
The global obesity problem is becoming increasingly serious, with eight of the top ten causes of death in Taiwan in 2020 being related to obesity. Morbid obesity poses a significant threat to one's health and well-being. In recent years, bariatric surgery has emerged as a more effective treatment option for patients with morbid obesity. However, the procedure is not without risks. This study aims to examine the factors that impact the postoperative efficacy evaluation of patients with morbid obesity. This study uses a retrospective cross-sectional design, with medical records being collected retrospectively. The data was collected from patients who underwent bariatric surgery between July 1, 2017 and June 30, 2020 at a hospital in southern Taiwan. A total of 663 patients were included in the study and were observed for 1 year after the surgery. The independent variables included demographic variables, perceived symptoms variables, perceived lifestyle variables, and surgery-related variables, while the dependent variables included weight loss outcomes and complications. The prognostic factors affecting the postoperative efficacy evaluation of patients with pathological obesity were determined using multiple regression analysis and binary regression analysis. The study found that 65.6% of the participants were female, with an average age of 36.8 years. The results of the multiple regression and binary logistic regression showed that gender, age, BMI, diabetes, and smoking habit were the predictors of postoperative weight loss. Hypertension, diabetes, liver disease, kidney disease, smoking habit, drinking habit, and operation time were the predictors of postoperative complications. The study found that the presence of the aforementioned 12 significant factors can affect the success of weight loss after surgery and the incidence of postoperative complications. This information can serve as a reference for clinical care institutions and patients to improve the postoperative efficacy evaluation.

Abstract
Background No sex-specific guidelines for surgical anti-obesity strategies have been proposed, partially due to the controversy regarding sex-related differences in weight loss after bariatric metabolic surgery. Objectives To explore sex dimorphism in the effect and predictors of weight loss after sleeve gastrectomy (SG), thereby providing clinical evidence for the sex-specific surgical treatment strategy. Methods In a prospective cohort design, participants scheduled for SG at an affiliated hospital between November 2020 and January 2022 were assessed for eligibility and allocated to the Male or Female group with a 1-year follow-up after surgery. The primary outcome was the sex difference in the weight-loss effect after SG indicated by both percentage of total weight loss (TWL%) and excess weight loss (EWL%). The secondary outcome was the analysis of sex-specific preoperative predictors of weight loss after SG based on univariate and multivariate analyses. Independent predictors were obtained to construct a nomogram model. The discrimination, calibration, and clinical utility of the nomogram were based on receiver operating characteristic curve, concordance index, calibration curve, and decision curve analysis, respectively. Results Ninety-five male and 226 female patients were initially included. After propensity score matching by baseline body mass index (BMI), 85 male and 143 female patients achieved comparable TWL% and EWL% for 1 year after SG. For male patients, baseline BMI, area under the curve for insulin during oral glucose tolerance test, and progesterone were independent predictors of weight loss after SG. Baseline BMI, age, thyroid stimulating hormone, and Self-Rating Anxiety Scale score were independent predictors for female patients. Conclusion No obvious sex difference is detected in the weight-loss effect after SG. Sex dimorphism exists in the predictors of weight loss after SG. Further research with long-term and a multicenter design is needed to confirm the predictive model.

Sleeve Gastrectomy: Does the Amount of Stomach Removed Matter? Obes Surg 2023; 33:469-474. [PMID: 36474099 DOI: 10.1007/s11695-022-06383-4] [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: 05/20/2022] [Revised: 11/17/2022] [Accepted: 11/27/2022] [Indexed: 12/12/2022]
Abstract
PURPOSE Data regarding the associations between percent weight loss and the volume and weight of stomach resected during sleeve gastrectomy (SG) are mixed. The purpose of this study was to evaluate the effect of the size and volume of stomach removed during laparoscopic SG on percent total body weight lost (%TBWL). METHODS An observational case series study was performed on 67 patients for 1 year after SG at a single university-affiliated, tertiary care hospital. Data were collected on demographics, medical history, and %TBWL at 3, 6, and 12 months post-operatively. Pearson's correlation matrices and multiple linear regression analyses were performed. RESULTS Most patients (88.1%) were female with a mean age of 44 years. The mean volume of stomach resected was 1047.0 cubic centimeters, and the median weight resected was 123.0 g. Follow-up data were available for 44 patients at 1-year post-operation. There was no association between the volume and weight of stomach resected and %TBWL at 1-year post-operation; however, greater %TBWL was associated with younger patient age (r = - 0.525, p < 0.001). CONCLUSION One year after SG, no associations between %TBWL and the volume and weight of stomach resected were observed.

Abstract
Background: Very few models predict weight loss among type 2 diabetes mellitus (T2D) patients after laparoscopic sleeve gastrectomy (LSG). This retrospective study undertook such a task. Materials and Methods: We identified all patients >18 years old with T2D who underwent primary LSG at our institution and had complete data. The training set comprised 107 patients operated upon during the period April 2011 to June 2014; the validation set comprised 134 patients operated upon during the successive chronological period, July 2014 to December 2015. Sex, age, presurgery BMI, T2D duration, number of T2D medications, insulin use, hypertension, and dyslipidemia were utilized as independent predictors of 1-year BMI. We employed regression analysis, and assessed the goodness of fit and "Residuals versus Fits" plot. Paired sample t-tests compared the observed and predicted BMI at 1 year. Results: The model comprised preoperative BMI (β = 0.757, P = 0.026) + age (β = 0.142, P < 0.0001) with adjusted R2 of 0.581 (P < 0.0001), and goodness of fit showed an unbiased model with accurate prediction. The equation was: BMI value 1 year after LSG = 1.777 + 0.614 × presurgery BMI (kg/m2) +0.106 × age (years). For validation, the equation exhibited an adjusted R2 0.550 (P < 0.0001), and the goodness of fit indicated an unbiased model. The BMI predicted by the model fell within -3.78 BMI points to +2.42 points of the observed 1-year BMI. Pairwise difference between the mean 1-year observed and predicted BMI was not significant (-0.41 kg/m2, P = 0.225). Conclusions: This predictive model estimates the BMI 1 year after LSG. The model comprises preoperative BMI and age. It allows the forecast of patients' BMI after surgery, hence setting realistic expectations which are critical for patient satisfaction after bariatric surgery. An attainable target motivates the patient to achieve it.

Abstract
PURPOSE Weight loss before bariatric surgery is not mandatory, but questions remain as to whether preoperative weight loss has an impact on weight loss after surgery. Most studies have small sample sizes. The objective was to evaluate the relationship between preoperative and successful postoperative weight loss defined as ≥25% total weight loss (TWL) at 1 and 2 years after primary bariatric surgery with regard to the obesity-related comorbidities. MATERIALS AND METHODS Data were extracted from a large nationwide quality registry of patients who underwent a sleeve gastrectomy (SG) or gastric bypass (GBP) between January 2015 and January 2018. Patients with completed screening and preoperative and postoperative data were included. A multivariate logistic regression analysis was performed for each technique and follow-up years separately. RESULTS In total, 8751 were included in the analysis. Patients with preoperative weight loss were more likely to achieve ≥25% postoperative TWL in both procedures. Patients with higher preoperative weight loss of 5-10% had an increased likelihood for achieving 25% TWL compared to 0-5%, OR 1.79 (CI (1.42-2.25), p < 0.001) vs 1.25 (CI (1.08-1.46), p < 0.004) for the GBP group for year 2 postoperative. This was the same for the SG group at year 2, OR 1.30 (CI (1.03-1.64), p < 0.029) vs 1.14 (CI (0.94-1.38), p < 0.198). CONCLUSION Patients with preoperative weight loss were more likely to achieve ≥25% postoperative TWL at 1 and 2 years after surgery in both procedures; moreover, the extent of preoperative weight loss contributes to the significance and odds of this success.

Abstract
BACKGROUND Patients with obesity show evidence of increased levels of inflammation, oxidative stress and premature ageing. Telomere length (TL) is a key marker of cellular ageing, and patients with obesity often present shorter TL. Bariatric surgery (BS) is currently the most effective treatment for severe obesity. The aim of this systematic review was to explore whether the beneficial health effects observed after surgery in obese patients correspond to a restoration in TL or slower rates of shortening. As a secondary aim, we evaluated, at baseline and post-surgery, the relationship between TL and different factors that could play a role in TL changes along time. METHODS Searches for relevant articles were performed in MEDLINE, Web of Knowledge and SCOPUS. Prospective longitudinal studies that evaluated leukocyte TL in adult patients who had undergone BS were included. Data were extracted and evaluated by two independent researchers. The protocol was registered in PROSPERO with the number CRD42020197711. RESULTS Seven studies based on independent samples that fulfilled our inclusion criteria were included. Obese patients showed shorter telomeres compared to healthy individuals. Long-term studies (>2 years) seem to suggest an improvement in TL after surgery presumably due to the improvement of the inflammatory and oxidative levels of the patients induced by weight loss. CONCLUSION Studies seem to point towards a beneficial long-term effect of BS on TL recovery. However, the scarce number of studies and the heterogeneity in the variables analysed in the different cohorts make it difficult to draw a firm conclusion. More studies are needed to evaluate long-term changes to TL following BS.

Abstract
Despite the initial successful weight loss after bariatric surgery, a significant amount of patients experience weight loss failure and weight regain. Several factors are known to contribute to this, though the impact of employment status is unknown. The objective of this systematic review was to examine the impact of employment status on post-surgical weight loss outcomes. Eight studies were included with a follow-up ranging between 2 and 10 years. Employed patients seemed to present more weight loss (9.0-11.0% EWL, 1.3-1.6% BMI loss) compared to unemployed patients, but none of these numbers were statistically significant. Moreover, there were contrasting findings in terms of weight regain. This review may highlight the importance of working status after bariatric surgery and warrants further investigation on this topic.

Impact of smoking on weight loss outcomes after bariatric surgery: a literature review. Surg Endosc 2021; 35:5936-5952.

Abstract
BACKGROUND The association between smoking and surgical complications after bariatric surgery has been well-established. However, given that this patient population is inherently weight-concerned, understanding the effects of tobacco use on postoperative weight loss is essential to guiding clinicians in counseling patients. We aimed to summarize the current literature examining the effects of preoperative and postoperative smoking, as well as changes in smoking status, on bariatric surgery weight loss outcomes. METHODS Ovid MEDLINE, PubMed, and SCOPUS databases were queried to identify relevant published studies. RESULTS Overall, 20 studies were included. Preoperative and postoperative smoking rates varied widely across studies, as did requirements for smoking cessation prior to bariatric surgery. Reported preoperative smoking prevalence ranged from 1 to 62%, and postoperative smoking prevalence ranged from 6 to 43%. The majority of studies which examined preoperative and/or postoperative smoking habits found no association between smoking habits and postoperative weight loss outcomes. A minority of studies found relatively small differences in postoperative weight loss between smokers and nonsmokers; these often became nonsignificant with longer follow-up. No studies found significant associations between changes in smoking status and weight loss outcomes. CONCLUSION While smoking has been associated with weight loss in the general population, most current evidence demonstrates that smoking habits are not associated with weight loss outcomes after bariatric surgery. However, due to the heterogeneity in study design and analysis, no definitive conclusions can be made, and more robust studies are needed to investigate any relationship between smoking and long-term weight loss outcomes. Given the established increased risk of surgical complications and mortality in smokers, smoking cessation should be encouraged.

Abstract
Background Low socioeconomic status (SES) is associated with an increased prevalence of obesity. It is unknown whether SES influences the outcome after bariatric surgery in Germany. Therefore, the aim of our study was to investigate whether the SES is linked with an inferior outcome after bariatric surgery. Methods We included all patients who underwent bariatric surgery in our university hospital from 2012–2014. Net income was estimated by matching the zip codes of patient residency with the region-specific purchasing power index. We analyzed the relationship between SES, weight loss and remission of comorbidities. Results We included 559 patients in this study and detected a mean 5-year percentage excess weight loss (%EWL) of 52.3%. We detected a significantly lower initial body mass index (BMI) and weight in patients with a higher income. One year after surgery, we did not find a significant difference. Further analysis revealed that only women with a higher income had a significantly lower BMI and weight 3 and 5 years after surgery. Conclusions Bariatric surgery is beneficial for all patients regardless of income. Furthermore, we demonstrated that women with high SES have a better outcome after bariatric surgery.

Social determinants of health and their impact on rates of postoperative complications among patients undergoing vertical sleeve gastrectomy. Surgery 2021; 171:447-452. [PMID: 34303546 DOI: 10.1016/j.surg.2021.06.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 06/07/2021] [Accepted: 06/11/2021] [Indexed: 01/26/2023]
Abstract
BACKGROUND Vertical sleeve gastrectomy is one of the most common bariatric procedures worldwide, but the impact of social determinants of health on postoperative outcomes for this procedure has not been well characterized. The objective of this study was to analyze the impact that social determinants of health have on postoperative outcomes after vertical sleeve gastrectomy. METHOD This was a population-based study using the MARINER-15 database, an all-payer claims database. The primary endpoint of this study was the development of any complication, including cardiac complication, acute kidney injury, deep vein thrombosis, wound complication, hematoma, pneumonia, pulmonary embolism, transfusion, or urinary tract infection within 60 days, 30- and 90-day all-cause mortality, or readmission within 30 or 90 days in patients undergoing vertical sleeve gastrectomy procedures. RESULTS Individuals in the social determinants of health cohort had a significantly longer length of stay when compared with those without social determinants of health (3.07 days vs 1.582 days, P < .001). These patients were more likely to develop any complication within 60 days after surgery (hazard ratio 1.20, 95% confidence interval 1.03-1.40) but were less likely to return for readmission within 30 and 90 days (hazard ratio 0.80, 95% confidence interval 0.66-0.96; hazard ratio 0.85 95% confidence interval 0.72-0.99). CONCLUSION Vertical sleeve gastrectomy is an effective treatment for morbid obesity and its associated comorbidities. Although patients with social determinants of health are more likely to develop any of the analyzed postoperative complications within 60 days, they are less likely to return for readmission, highlighting the importance of focused follow-up and other measures to avoid lapses in care and eliminate further barriers to care in this population.

Abstract
BACKGROUND The prevalence of smoking among patients undergoing bariatric surgery has been reported to be as high as 40%. The effect of smoking in the perioperative period has been extensively studied for various surgical procedures, but limited data are available for bariatric surgery. The objective of this study is to review the existing literature to assess: (1) the impact of smoking on postoperative morbidity and mortality after bariatric surgery, (2) the relationship between smoking and weight loss after bariatric surgery, and (3) the efficacy of smoking cessation in the perioperative period among bariatric surgery patients. METHODS A comprehensive search of electronic databases including MEDLINE, EMBASE and the Cochrane Library from 1946 to February 2020 was performed to identify relevant articles. Following an initial screen of 940 titles and abstracts, 540 full articles were reviewed. RESULTS Forty-eight studies met criteria for analysis: five structured interviews, three longitudinal studies, thirty-two retrospective studies and eight prospective studies. Smoking within 1 year prior to bariatric surgery was found to be an independent risk factor for increased 30-day mortality and major postoperative complications, particularly wound and pulmonary complications. Smoking was significantly associated with long-term complications including marginal ulceration and bone fracture. Smoking has little to no effect on weight loss following bariatric surgery, with studies reporting at most a 3% increased percentage excess weight loss. Rates of smoking recidivism are high with studies reporting that up to 17% of patients continue to smoke postoperatively. CONCLUSIONS Although current best practice guidelines recommend only a minimum of 6 weeks of abstinence from smoking prior to bariatric surgery, the findings of this review suggest that smoking within 1 year prior to bariatric surgery is associated with significant postoperative morbidity. More investigation is needed on strategies to improve smoking cessation compliance among bariatric surgery patients in the perioperative period.

Abstract
BACKGROUND Metabolic surgery is the most effective method for weight loss in the long-term treatment of morbid obesity and its comorbidities. The primary aim of this study was to examine factors associated with percent total weight loss (%TWL) after metabolic surgery among an ethnically diverse sample of patients. METHODS A retrospective review was performed on 1012 patients who underwent either a sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) at our institution between January 2008 and June 2015. RESULTS African Americans had a lower %TWL than non-Hispanic/Latino Whites at 6, 9, 12, 18, and 48 months. At all timeframes, there was a negative association between pre-surgery TWL and %TWL after surgery. Female sex was negatively associated with %TWL at 3 months only. Higher initial BMI was also associated with greater post-operative %TWL at 18, 24 and 36 months. Older patients had lower %TWL at 6, 9, 12 and 24 months post-surgery. Patients who received RYGB had greater %TWL than those who received SG at 3, 6, 9, 12, 24 and 36 months. CONCLUSIONS African Americans had a lower %TWL than non-Hispanic/Latino Whites at most time points; there were no other significant race/ethnicity or sex differences. BMI (greater initial BMI), age (lower) and RYGB were associated with a greater post-operative %TWL at certain post-surgery follow-up time points. A limitation of this study is that there was missing data at a number of time points due to lack of attendance at certain follow-up visits.

Abstract
Bariatric surgery is effective in treating obesity in many cases, yet as many as 50% of patients may not achieve the desired weight reduction. Preoperative modifiable behavioural factors could help patient selection and intervention design to improve outcomes. Medline, EMBASE, Cochrane Library and PsychINFO were searched to identify studies published between 1 January 2008 and 14 February 2019 reporting on preoperative modifiable behavioural factors associated with postoperative weight loss, with minimum 2 years follow-up. A total of 6888 articles were screened, 34 met the inclusion criteria. Maladaptive eating behaviours (MEB), preoperative weight loss (PWL), and tobacco use were reported 21, 18, and 3 times respectively. Physical activity and substance abuse were each reported once. Most articles on PWL (72.2%) and MEB (52.4%) reported no association. Positive associations were reported in 22.2% and 14.3% of articles for PWL and MEB respectively. Negative associations were reported in 5.6% and 33.3% of articles for PWL and MEB, respectively. Marked heterogeneity in outcome reporting hindered quantitative synthesis. The current paucity of evidence amenable to synthesis leads to ongoing uncertainty regarding the size and direction of association between PWL and MEB with outcomes following bariatric surgery. Long-term studies with common reporting of outcomes are needed.

Abstract
INTRODUCTION Bariatric surgery is considered the most effective treatment for severe obesity. However, it is not clear if patients with diabetes mellitus or insulin resistance have the same response than patients without those conditions. Our objective was to evaluate association between pre-surgical HOMA-IR index and percentage of excess weight loss (EWL%) one year after bariatric surgery using sleeve gastrectomy. METHODS Retrospective cohort including patients ≥18 years old with BMI≥35kg/m2, who underwent primary sleeve gastrectomy between 2014-2017 at the Avendaño Medical Center, Peru. Only patients with Type 2 Diabetes, Hypertension, or Dyslipidemia were included. EWL% ≥60% one year after surgery was considered satisfactory. Crude and adjusted Lineal and Poisson regression with robustness was used to assess statistical associations with EWL%. RESULTS Ninety-one patients were included with a median of 34 years, and 57.1% were women. 85.7% had insulin resistance as per HOMA-IR. One year after surgery, 76.9% had a satisfactory EWL%. The lineal model showed .29% less EWL% per each extra year of life (P=.019), and .93% more EWL% per each extra HOMA-IR point (P=.004). The adjusted Poisson model showed 2% lower risk of having a satisfactory EWL% per each additional year of life (P=.050), and 2% more chance of success per each additional HOMA-IR point (P=.038). CONCLUSIONS There was association between a higher pre-surgical HOMA-IR index and increased EWL% one year after surgery. It is possible that insulin resistance does not affect negatively sleeve gastrectomy outcomes.

Abstract
BACKGROUND Emerging evidence suggests that the FK506 binding protein 51 (FKBP5/FKBP51), encoded by the FKBP5 gene, influences weight and metabolic regulation. The T allele of a functional polymorphism in FKBP5 (rs1360780), has been associated with the expression of FKBP51 and weight loss after bariatric surgery. OBJECTIVE To examine the role of the FKBP5 rs1360780 polymorphism in relation to age, sex, and type of surgery in weight loss after bariatric surgery in patients with severe obesity. SETTING University Hospital in Spain METHODS: A cohort of 151 obese patients submitted to Roux-en-Y gastric bypass (62.3%) and sleeve gastrectomy (37.7%) were followed-up during 24-months (t24m; loss to follow-up: 0%). During the postoperative period body mass index (BMI) and percentage of excess and total weight loss were evaluated. RESULTS The BMI analysis showed an effect of the interaction FKBP5 genotype by sex (P = .0004) and a tendency to the interaction genotype by surgery (P = .048), so that men carrying the T allele had higher BMI at t24m than those without the T allele, and T-allele carriers that underwent sleeve gastrectomy had higher BMI at t24m than the noncarriers. Additionally, we found an interaction between FKBP5 and age for the percentage of excess weight loss and BMI (P = .0005 and P = 1.5e-7, respectively), whereby individuals >48 years with the T allele displayed significant differences for the analyzed variables at t24m compared with the homozygotes for the alternate C allele showing lower weight loss. CONCLUSION FKBP5 rs1360780 genotype has specific effects on weight loss outcomes after bariatric surgery depending on sex, age, and type of surgery, suggesting worse results in older males carrying the T allele who have undergone sleeve gastrectomy.

Preoperative liking and wanting for sweet beverages as predictors of body weight loss after Roux-en-Y gastric bypass and sleeve gastrectomy. Int J Obes (Lond) 2019; 44:1350-1359.

Abstract
Background/objectives: Patients who receive Roux-en-Y gastric bypass (RYGB) lose more weight than those who receive vertical sleeve gastrectomy (VSG). RYGB and VSG alter hedonic responses to sweet flavor, but whether baseline differences in hedonic responses modulate weight loss after RYGB or VSG remains untested. Participants/methods: Male and female candidates (n=66) for RYGB or VSG were recruited and tested for their subjective liking and wanting ratings of sucrose solutions and flavored beverages sweetened with aspartame. Participants were classified by unsupervised hierarchical clustering for their liking and wanting ratings of sucrose and aspartame. Participant liking ratings were also used in a supervised classification using pre-established categories of liking ratings (liker, disliker, and inverted u-shape). Effects of categories obtained from unsupervised or supervised classification on body weight loss and their interaction with surgery type were analyzed separately at 3 and 12 months after surgery using linear models corrected for sex and age. Results: RYGB participants lost more body weight compared to VSG participants at 3 and 12 months after surgery (P < 0.001 for both time points). Unsupervised clustering analysis identified clusters corresponding to high and low wanting or liking ratings for sucrose or aspartame. RYGB participants in high-wanting clusters based on sucrose, but not aspartame, lost more weight than VSG at both 3 (P = 0.01) and 12 months (P = 0.03), yielding a significant cluster by surgery interaction. Categories based on supervised classification using liking ratings for sucrose or aspartame showed no significant effects on body weight loss between RYGB and VSG participants. Conclusions: Classification of patients into high/low wanting ratings for sucrose before surgery can predict differential body weight loss after RYGB or VSG in adults and could be used to advise on surgery type.

Abstract
Bariatric surgery has been recognized as the gold standard treatment for severe obesity. Although postbariatric surgery patients usually achieve and maintain substantial weight loss, a group of individuals may exhibit weight regain. Several factors are proposed to weight regain, including psychiatric comorbidity. The objective of the study is to conduct a systematic review and meta-analysis of studies investigating the relationship between psychiatric comorbidity and weight regain. A systematic review through PubMed, Web of Science, Cochrane Library, Scopus, and PsycINFO was performed, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). After a stepwise selection, 13 articles were included in the qualitative analysis and 5 were included for a meta-analysis. Women was majority in most of the studies (87.6%), and a bypass procedure was the bariatric intervention most evaluated (66.8%), followed by gastric banding (32.1%) and sleeve (1.1%). Higher rates of postbariatric surgery eating psychopathology were reported in patients with weight regain. However, the association between general psychopathology and weight regain was not consistent across the studies. In the meta-analysis, the odds of eating psychopathology in the weight regain group was higher compared with the nonweight regain group (OR = 2.2, 95% CI 1.54-3.15). Postbariatric surgery eating psychopathology seems to play an important role in weight regain.

Preoperative exercise as a predictor of weight loss in adolescents and young adults following sleeve gastrectomy: a cohort study. Surg Obes Relat Dis 2019; 15:1051-1057.

Abstract
BACKGROUND Preoperative exercise is associated with weight loss following bariatric surgery in adults, but this relationship in adolescents and young adults (AYA) is not well studied. OBJECTIVES The present study examined AYA-reported preoperative exercise and demographic factors and their prediction of percent excess body mass index (BMI) loss at 6 and 12 months following sleeve gastrectomy. SETTING The setting for recruitment and surgeries was in a children's hospital in the United States. METHODS Participants were 173 AYA aged 12-21 years (mean age, 16.5 [SD, 2.0] yr; mean preoperative BMI, 50 [SD, 8.5] kg/m2). Demographic characteristics including age, sex, ethnicity, and preoperative BMI were extracted from the medical record. Preoperatively, adolescents self-reported on exercise using 5 items from the Center for Disease Control's Youth Risk Behavior Surveillance Survey. The study evaluated the association of self-reported preoperative exercise in total and obtained a threshold of higher exercise to weight loss at 6 and 12 months after surgery. RESULTS More preoperative exercise was associated with greater weight loss at 12 months. Grouping participants by those who reported exercising at high levels (≥5 hr/wk) compared with those who reported <5 hr/wk, high levels of exercise predicted greater weight loss at 6 and marginally at 12 months postoperatively. Lower preoperative BMI was a significant predictor of weight loss in all analyses. CONCLUSIONS Preoperative exercise may predict and contribute to weight loss in AYA and could be a target for pre- and postoperative intervention to improve outcomes. The importance of lower preoperative BMI for maximizing postoperative weight loss was also supported.

Abstract
PURPOSE Obesity is a multifactorial disease characterized by genetic, social, cultural and psychological factors. Currently, bariatric surgery represents the gold-standard intervention to treat morbid obesity in order to counteract associated disabling comorbidities. Several studies showed correlation between post-surgery weight loss and psychological factors. Also, the alexithymia may have a role in affecting post-surgery outcomes in bariatric patients, even if there are no studies investigating its role at 12-month follow-up. The purpose of the present study was to investigate the association between alexithymia and the postoperative weight loss 12 months after laparoscopic sleeve gastrectomy. METHODS Seventy-five patients undergoing laparoscopic sleeve gastrectomy were enrolled. The Toronto Alexithymia Scale (TAS-20) was administered to patients. A postoperative weight loss check was performed at 3 and then 12 months after surgery. RESULTS The TAS-20 total score was negatively correlated with the percent of excess weight loss (%EWL) at the 12-month follow-up (r = -0.24; p = 0.040). The analysis showed that non-alexithymic patients had a greater weight loss at 12 months after surgery compared to both probably alexithymics (71.88 ± 18.21 vs. 60.7 ± 12.5; p = 0.047) and probably alexithymic patients (71.88 ± 18.21 vs. 56 ± 22.8; p = 0.007). The preoperative BMI was a significant covariate [F(1,70) = 6.13 (p = 0.016)]. CONCLUSION In the present study, the patients with higher preoperative BMI and identified as alexithymic showed lower %EWL at 12 months after laparoscopic sleeve gastrectomy. Findings point out the importance to take into consideration possible psychological treatments focused on improving emotional regulations of patients who are seeking bariatric surgery.

Abstract
OBJECTIVES Bariatric surgery is an effective treatment for youth with severe obesity. However, outcomes are variable and there remains sparse understanding of predictors of weight loss following surgery. The current study examines the role of adolescent-reported pre-operative social support around exercise, binge eating, and exercise to predict excess body mass index (EBMI) loss from 3 to 12 months post-surgery. METHOD Participants were 101 adolescents ages 12-21 (M age = 16.6, SD = 1.8). Pre-operative body mass index (BMI) ranged from 35 to 87 (M = 50.3, SD = 8.6). Structural equation modeling (SEM) was used to evaluate a model of the association of adolescent report of perceived social support for exercise with less binge eating (items from the Eating Disorder Diagnostic Scale) and more self-reported exercise (items from the Youth Risk Behavior Surveillance System). The model was used to predict EBMI loss at 3, 6, 9, and 12 months post-surgery. RESULTS Social support significantly predicted exercise and demonstrated a trend for predicting binge eating, such that more social support was associated with more exercise and a trend for less binge eating. Binge eating was associated with less EBMI loss. However, there was no association of exercise with EBMI loss. CONCLUSIONS Pre-operative binge eating should be a target for identification and treatment prior to sleeve gastrectomy in adolescents. Although not directly or indirectly associated with EBMI loss, perceived social support around exercise was associated with increased exercise, which may make it a consideration for a target for intervention as well.

Abstract
BACKGROUND The relation between the resected gastric volume and the weight loss after laparoscopic sleeve gastrectomy appears conflicting in the literature. Both the residual and the resected volumes represent the total gastric volume, and if the weight loss is related to one of the two volumes, it should be related to the other. While some reports indicate that the weight loss is related to the resected gastric volume, others state that the weight loss is not related to the residual volume. The aim is to investigate the influence of the resected gastric volume on the weight loss after surgery. METHODS The study included 287 consecutive patients. Gastrectomy was performed encroaching over a 38-Fr calibrating tube all the way to the angle of His. Filling volume of the resected stomach, with tap water, was measured. Patients were analyzed into group 1 with BMI ≤50 kg/m(2) and group 2 >50 kg/m(2). RESULTS Females represented 74 % of cases. Mean age was 32.9 ± 9.5 years; preoperative BMI = 48.7 ± 7.9 kg/m(2). The mean resected gastric volume was 1525 ± 408 ml, and it was significantly lower in females compared to that in males (1443 ± 311 vs 1824 ± 502 ml, p < 0.001). Data were analyzed in two groups: group 1 with BMI ≤5050 kg/m(2) and group 2 >50 kg/m(2). Both groups were similar in preoperative BMI (p = 0.399) and excess weight percent (EW%) (p = 0.33). Group 2 had a resected gastric volume (1663 ± 424.7 ml) greater than that of group 1 (1440 ± 347 ml; p < 0.001). The percentage of excess weight loss (EWL%) was 57.9 ± 14.5 % at 6 months (62.7 ± 13.5 % vs 48.34 ± 11.29 %, p < 0.001), 77 ± 19 % at 12 months (84 ± 19.6 % vs 68 ± 14.2 %, p = 0.001), 76.6 ± 7.4 % at 18 months (79.7 ± 4.8 vs 74.7 ± 8.2 %, p = 0.5), and 75.8 ± 11.5 % at 24 months (81.7 ± 11.17 vs 70 ± 11 %, p = 0.8) (group 1 vs group 2, respectively). At 12 months, 86 % patients achieved more than 50 % EWL% (100 % of group 1 vs 60 % of group 2). Preoperative BMI correlated with resected gastric volume (r = 0.239, p = 0.004). In multiple regression, the initial BMI was a predictor of EWL% at 6 and 12 months (r partial = -0.65, p < 0.0001) while the resected gastric volume was not. CONCLUSIONS The resected gastric volume is related to the total gastric volume when the technique is standardized and the residual volume is calibrated using a consistent technique. It is not in itself a predictor of weight loss, but it is related to the initial BMI which predicts the weight loss.

Abstract
Purpose: To determine whether preoperative weight loss goals are associated with postoperative weight loss and whether the effect is modified by preoperative depressive symptoms. Methods: Sixty-three women from an ongoing cohort study who were undergoing first-time bariatric surgery at a large, academic hospital in Pittsburgh, PA, were included in this subanalysis. They were assessed preoperatively and 12 months postoperatively in regard to anthropometric and biobehavioral factors. Multivariable linear regression models were used to estimate associations between weight loss goals, expressed as percentage excess body mass index loss (%EBMIL), and postoperative %EBMIL, as well as test effect modification by depressive symptoms. Findings: Presurgery weight loss goals were positively associated with %EBMIL 12 months after bariatric surgery (β = 1.0, p < 0.01), adjusting for preoperative body mass index, age, race, and marital status; this relationship was negatively modified by depressive symptoms (β = -0.1, p = 0.02). The association between goal %EBMIL and postoperative %EBMIL was attenuated when type of surgery was added to the model. Conclusions: This initial report suggests that weight loss goals and depressive symptoms may be associated with achieved weight loss after bariatric surgery. If confirmed in larger cohorts, these findings may indicate that more personalized approaches will be needed when discussing weight loss goals with patients.

Abstract
BACKGROUND Gender might be important in predicting outcomes after bariatric surgery. The aim of the study was to investigate the influence of gender on long-term weight loss and comorbidity improvement after laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). METHODS A cohort of 304 consecutive patients underwent surgery in 2006-2009: 162 (98 women, 64 men) underwent LSG and 142 (112 women, 30 men) underwent LRYGB. The mean follow-up time was 75.8 ± 8.4 months (range, 60-96 months). RESULTS Overall mean (95% CI) reduction in BMI was 23.5 (24.3-22.7) kg/m(2) after 5 years, with no statistical difference between LSG and LRYGB groups (P = 0.94). The overall means ± standard deviations of %EBMIL after 5 years were 78.8 ± 23.5 and 81.6 ± 21.4 in the LSG and LRYGB groups, respectively. Only for LSG group %EBMIL after 24-36 and 60 months differed significantly between male and female patients (P = 0.003 versus P = 0.06 in LRYGB), and 89 versus 90% of patients showed improvements in comorbidities in the LSG and LRYGB groups, respectively. Only two patients (women) were lost to follow-up: 1/162 (0.6%) for LSG at the 4th year and 1/142 (0.7%) for LRYGB to the 5th year. CONCLUSIONS LSG was more effective in obese male than in female patients in terms of %EBMIL, with no difference in comorbidities. LRYGB elicited similar results in both genders in terms of %EBMIL and comorbidities.

Abstract
INTRODUCTION Despite the rapidly increasing popularity of laparoscopic sleeve gastrectomy (LSG), there is limited data examining weight loss more than 1 year after the procedure. There have also been few studies examining baseline predictors of weight loss after LSG. We aimed to examine the percentage of excess weight loss (%EWL) in patients 2 years after LSG and identify baseline predictors of %EWL. METHODS Electronic records from university hospitals were available for 292 patients who underwent LSG (205 women; mean age, 41.5 ± 11.1 years; mean weight, 126.5 ± 27.5 kg; mean BMI, 45.5 ± 7.5 kg/m(2) ). Variables assessed for predictive effect were baseline age, sex, BMI, presence of comorbidities (diabetes, hypertension, or obstructive sleep apnea), the amount of weight loss induced by a very low-calorie diet before surgery, and the number of clinic appointments attended over the 2 years. We performed linear regression and mixed model analyses between predictor variables and %EWL at 2 years. RESULTS Adjusted %EWL was 31% at 2 weeks, 49% at 3 months, 64% at 6 months, 70% at 9 months, 76% at 12 months, 79% at 18 months, and 79% at 2 years. Multivariate analysis showed that lower baseline BMI, absence of hypertension, and greater clinic attendance predicted better %EWL (r(2) = 0.11). CONCLUSION Longer-term follow-up studies of weight loss post LSG are required to assist with patient care and management.

Abstract
Fewer men than women with severe obesity undergo bariatric surgery for weight loss, and knowledge about men's situation after surgery, beyond medical status, is lacking. Our aim was to explore men's experiences with life after bariatric surgery from a long-term perspective. We conducted in-depth interviews with 13 men, aged 28–60 years, between 5 and 7 years after surgery. The analysis was inspired by Giorgi's phenomenological method. We found that agency was pivotal for how the men understood themselves and their lives after surgery. Weight loss meant regaining opportunities for living and acting in unrestricted and independent daily lives, yet surgery remained a radical treatment with complex consequences. Turning to surgery had involved conceptualizing their own body size as illness, which the men had resisted doing for years. After surgery, the rapid and major weight loss and the feelings of being exhausted, weak, and helpless were intertwined. The profound intensity of the weight loss process took the men by surprise. Embodying weight loss and change involved an inevitable renegotiating of experiences connected to the large body. Having bariatric surgery was a long-term process that seemed unfinished 5 years after surgery. Restrictions and insecurity connected to health and illness persist, despite successful weight loss and embodied change. Bariatric surgery initiated a complex and long-lasting life-changing process, involving both increased capacity for agency and illness-like experiences.

Abstract
We aim to summarize the existing evidence on the use of single incision sleeve gastrectomy (SILSG) for morbid obesity. A thorough literature search for studies reporting outcomes of SILSG was performed. Data on patient demographics, operative details, and surgical outcomes were analyzed. Sixteen studies incorporating 945 patients (90.6 % women) with a mean age of 37 years were included in the analysis. A commercially available single-port device was used in 89.7 % of the cases. The mean operative time was 64.7 min, with two cases (0.2 %) of intraoperative and 27 cases (2.8 %) of postoperative complications. There were no perioperative deaths reported, while the mean postoperative hospital stay was 2.5 days. SILSG is a feasible and safe approach, with low complication and mortality rates in carefully selected patients.
