Abu-Zeid EED, Atias S, Netz U, Golani G, Avital I, Perry ZH. Gender Comparisons of Surgical Outcomes in Patients Undergoing One Anastomosis Gastric Bypass (OAGB): a Historical Cohort Study. Obes Surg 2024; 34:98-105. [PMID: 38010452 DOI: 10.1007/s11695-023-06954-z] [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: 08/05/2023] [Revised: 11/08/2023] [Accepted: 11/13/2023] [Indexed: 11/29/2023]
Abstract
INTRODUCTION AND PURPOSE Clinical trials in the field of bariatrics have frequently been gender imbalanced, with males representing only 20% of examinees. Long-term gender-oriented results in one anastomosis gastric bypass (OAGB), and specifically quality of life (QOL) parameters, have not been addressed sufficiently. A better understanding of gender's effect on OAGB outcomes can play an important role in selecting the appropriate bariatric surgery for patients. Our study was aimed at examining mid-term gender-associated outcome of OAGB, including the effect on QOL. MATERIALS AND METHODS A retrospective cohort study of patients who underwent OAGB at surgical ward A, SUMC, Israel, between 2015 and 2020. Demographics, body mass index (BMI), and comorbidities were extracted from the national medical records system. Follow-up quality of life (QOL) and weight parameters were supplemented via telephone questionnaires, using the Bariatric Analysis and Reporting Outcome System (BAROS). RESULTS A total of 152 patients were included; of these, 51 (33.6%) were males, with an average follow-up period of 4.1 (± 1.3) years post-surgery. Basic demographics showed no significant pre- or post-surgery differences between males and females, except for pre-op weight (which as expected was higher for males). Males had a higher overall BAROS score than females (3.8 ± 2.1 vs. 2.6 ± 2.1, p < 0.001). CONCLUSIONS OAGB surgery results in better outcomes for male than for female patients as measured by the BAROS, despite a similar BMI reduction, and with no difference in complications. Gender-specific outcomes are one of the variables that one should be aware of in optimizing patient selection and pre-operative patient counseling.

The effects of bariatric surgery on dyslipidemia and insulin resistance in overweight patients with or without type 2 diabetes: a systematic review and network meta-analysis. Surg Obes Relat Dis 2021; 17:1655-1672.

Abstract
Obesity has become an epidemic in several regions globally; it may lead to cardiovascular diseases, diabetes, and dyslipidemia. Despite many therapies, all bariatric procedures fail in some patients. There is a lack of literature comparing treatment effects on specific metabolic indexes. PubMed, Embase, and Cochrane Central Register of Controlled Trials were searched for relevant articles. GeMTC and R software were used to perform a network meta-analysis, draw forest plots, investigate the possibility of statistical heterogeneity, generate I2 statistics, rank probabilities, and evaluate relative effects of surgical procedures. All analyses were based on a Bayesian consistency model. We included 35 randomized controlled trials, comprising 2198 individuals and 13 interventions. For patients with high insulin resistance, single-anastomosis (mini-) gastric bypass (SAGB) and sleeve gastrectomy (SG) may be effective options, with mean differences (95% confidence intervals [CIs]) of -4.45 (-9.04 to -.34) and -4.23 (-6.74 to -2.22), respectively, compared with control groups. For patients with severe dyslipidemia, in addition to SAGB and SG, duodenal switch (DS) may be an effective surgery, with mean differences (95% CIs) of -.97 (-1.39 to -.55), -1.98 (-3.76 to -.19), .53 (.04 to 1.04), and -.94 (-1.66 to -.16) compared with control groups in terms of triglycerides, total cholesterol, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) concentrations, respectively. In adult overweight patients with or without diabetes, SAGB and SG are most effective at ameliorating insulin resistance. SAGB, Roux-en-Y gastric bypass + omentectomy, and DS are useful for reducing triglycerides, total cholesterol, and LDL-C. SG + omentectomy elevates HDL-C concentrations best. Adjustable gastric band and biliopancreatic diversion may not control insulin resistance or dyslipidemia well.

Sleeve Volume and Preoperative Gastric Volume Assessment Using Three-dimensional MDCT Gastrography and Their Correlation to Short-term Post-Sleeve Gastrectomy Weight Loss. Obes Surg 2020; 31:490-498. [PMID: 33006088 DOI: 10.1007/s11695-020-05012-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 09/22/2020] [Accepted: 09/24/2020] [Indexed: 01/06/2023]
Abstract
PURPOSE Several factors including preoperative stomach capacity and sleeve volume impact weight loss after laparoscopic sleeve gastrectomy (LSG). We aimed at measuring these volumes using multidetector computed tomography (MDCT) gastrography and correlating them with postoperative weight losses. MATERIALS AND METHODS Morbidly obese patients prepared for LSG during 2018 were included in the study. MDCT gastrography was performed 1 week before, 6 and 12 months after LSG. Preoperative gastric volume and postoperative sleeve volumes were measured. Correlation with preoperative BMI and postoperative %TWL was performed. The change in sleeve volume at 6 and 12 months was assessed. RESULTS A total of 98 patients (62 F) were included. Mean preoperative BMI was47 ± 7 kg/m2. Follow-up was achieved in 89 patients (91%) and 82 patients (83%) at 6 and 12 months, respectively. Mean %TWL was 24 ± 3 and 32.8 ± 3 at 6 and 12 months, respectively (p < 0.05). Preoperative gastric volume ranged from 800 to 1800 ml (mean ± SD, 1310 ± 307) and dropped significantly to range from 140 to 170 ml (158 ± 9) and from 165 to 210 ml (181 ± 12) at 6 and 12 months postoperatively, respectively. Pouch was not significantly dilated at 12 vs. 6 months postoperatively. Preoperative gastric volume was significantly correlated with preoperative BMI (p = 0.006*) but not with postoperative weight losses. Correlation between postoperative pouch volumes and weight losses at 6 and 12 months postoperatively showed no significance. CONCLUSION Sleeve pouch is significantly smaller than preoperative stomach, but not significantly correlated to weight loss. Restriction is an important, but not the only factor controlling weight loss after LSG.

Very Low-Carbohydrate Ketogenic Diet for the Treatment of Severe Obesity and Associated Non-Alcoholic Fatty Liver Disease: The Role of Sex Differences. Nutrients 2020; 12:nu12092748.

Abstract
Very low-carbohydrate ketogenic diets (VLCKDs) are an emerging nutritional treatment for severe obesity and are associated with a significant improvement in non-alcoholic fatty liver disease (NAFLD). Little is known about the effect of sex differences on weight loss induced by following a VLCKD. The aim of this study was to investigate the effects of sex differences on weight loss and NAFLD improvement in patients with severe obesity undergoing a VLCKD. Forty-two females and 28 males with severe obesity underwent a 25-day VLCKD. Anthropometric parameters, bioimpedentiometry, degree of liver steatosis measured by ultrasonography, liver function tests, and glucose homeostasis were measured before and after the VLCKD. Males experienced a significantly larger excess body weight loss (EBWL) and a greater reduction in γ-glutamyl transferase (γGT) than females. Dividing the female group by menopausal status, a significant difference between males and pre-menopausal females was found for both EBWL and γGT. No significant difference between groups was observed for improvement in the Edmonton stage or in the degree of steatosis. We conclude that the efficacy of following a VLCKD in severe obesity is affected by sex differences and, for females, by menopausal status. Males seem to experience larger benefits than females in terms of EBWL and NAFLD improvement. These differences are attenuated after menopause, probably because of changes in hormonal profile and body composition.

Gender-related metabolic outcomes of laparoscopic sleeve gastrectomy in 6-month follow-up. Wideochir Inne Tech Maloinwazyjne 2020; 15:148-156. [PMID: 32117498 PMCID: PMC7020728 DOI: 10.5114/wiitm.2019.86800] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2019] [Accepted: 05/26/2019] [Indexed: 02/05/2023] Open
Abstract
Introduction Laparoscopic sleeve gastrectomy (LSG) is recently a leading method in surgical treatment of morbid obesity. The metabolic outcome of intervention may be a result of many factors such as age, gender, preoperative weight loss and dietary restrictions. Aim To evaluate gender-related differences in the results of LSG in 6-month follow-up. Material and methods The study included 101 patients who underwent LSG at the University Clinical Hospital of Bialystok. Patients were divided and analyzed in 2 groups: males (n = 48) and females (n = 53). The primary analysis included the influence of gender on postoperative weight loss calculated using the percentage of excess weight loss (%EWL) and excess BMI loss (%EBMIL). For secondary outcomes the levels of glucose, insulin, glycated hemoglobin, aspartate transaminase, alanine transaminase, total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides and C-reactive protein were analyzed. Results A significant influence of patients’ gender was proved for both %EWL (p = 0.026) and %EBMIL (p = 0.001). Females had significantly higher %EWL in 6-month follow-up than males (p = 0.0034). The analysis also showed significantly higher %EBMIL for women at 3 and 6 months observation (p = 0.022 and p < 0.001 respectively). Conclusions Laparoscopic sleeve gastrectomy is an effective method of obesity treatment especially in terms of postoperative weight loss. Females seem to benefit more from the procedure when analyzing the parameters of body mass reduction. However, further research is needed to provide strong evidence of an association between gender and the results of LSG.

Abstract
Lifestyle intervention programs are effective in the prevention of type 2 diabetes mellitus (T2DM) in high risk populations. However, most studies only give limited information about the influence of sex and/or gender effectiveness of these interventions. So far, similar outcome was reported for diabetes progression and weight loss. Nevertheless, long-term data on cardiovascular outcome are sparse but favoring women regarding all-cause and cardiovascular mortality. In both men and women, sex hormone imbalances and reproductive disorders are associated with a higher risk of T2DM development. Diabetes prevention approaches are reported for polycystic ovary syndrome, gestational diabetes mellitus, and erectile dysfunction and are presented in this review. In the surgical treatment options for morbid obese patients, sex and gender differences are present. Choices and preferences of adherence to lifestyle and pharmacological interventions, expectations, treatment effects, and complications are influenced by sex or gender. In general, bariatric surgery is performed more often in women seeking medical/surgical help to lose weight. Men are older and have higher comorbidities and mortality rates and worse follow-up outcome after bariatric surgery. A more gender-sensitive clinical approach, as well as consideration of ethnicity may improve quality of life and increase health and life expectancy in men and women with a high risk for subsequent progression to T2DM.

Abstract
BACKGROUND Clinical trials in the field of bariatrics, and specifically laparoscopic adjustable gastric banding (LAGB), have frequently been gender imbalanced, with males representing only 20% of examinees. Long-term gender-oriented results, and specifically quality of life (QOL) parameters, have not been addressed sufficiently. The aim of our study was to examine the long-term gender association with outcome of LAGB including the impact on QOL. METHODS A retrospective cohort study of patients who underwent LAGB between 2006 and 2014 by a single surgeon was conducted. Data were collected from the hospital registry and a telephone interview that included a standardized questionnaire. Outcomes including BMI reduction, evolution of comorbidities, complications, reoperations, and QOL were compared according to the Bariatric Analysis and Reporting Outcome System (BAROS). RESULTS Included were 114 males and 127 females, with a mean age of 38.2 years at surgery, and an average post-surgery follow-up of 6.5 years. Similar BMI reduction (p = 0.68) and perioperative complication rates (p = 0.99) were observed. Males had a greater improvement in comorbidities (p < 0.001), less band slippage (p = 0.006), underwent fewer reoperations (p = 0.02), and reported higher QOL scores (p = 0.02) than females. The total BAROS score was significantly higher for males than females (p < 0.001). CONCLUSIONS LAGB surgery results in better outcomes for male than female patients as measured by the BAROS, despite a similar BMI reduction. Gender-specific outcomes should be taken into consideration in optimizing patient selection and preoperative patient counseling.

Abstract
INTRODUCTION In 2013, a worldwide bariatric surgery survey showed that laparoscopic adjustable gastric banding (LAGB) has been abandoned in favor of laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-y gastric bypass (LRYGBP). PURPOSE The aim of this study was to compare results of LRYGBP and LSG performed as a revisional procedure after LAGB. MATERIALS AND METHODS All patients converted from LAGB to LSG or to LRYGBP from January 2007 to December 2011 were included in the study. Clinical data collected were age, gender, indications for revision, complications, body mass index (BMI), and body weight at revisional procedures. Weight loss was calculated at 1, 3, and 5 years after conversion. RESULTS Fifty-one patients were included in this study, 43 females and 8 males. Twenty-four patients were converted to LRYGBP (LRYGBP group) and 27 to LSG (LSG group). Indication for conversion was weight loss failure in 34 (67%) patients and band complications in 17 (33%) patients. No significant difference in age, BMI, and body weight in the two groups was found at the time of revision. One patient converted to LRYGBP had an internal hernia; one patient initially scheduled for LSG was intraoperatively converted to LRYGBP due to staple line leak. No other major perioperative complication was observed. Follow-up rate at 5 years was 84.3% (43 patients out of 51 patients) Delta-BMI and percentage of excess weight loss (%EWL) were not significantly different in the two groups at 1, 3, and 5 years (p > 0.05). CONCLUSION LRYGBP or LSG are feasible and effective surgical options after LAGB. Satisfactory weight loss was achieved after both procedures.

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
Background Since January 2005, the status of bariatric surgery in Germany has been examined in conjunction with a quality assurance study of the German Bariatric Surgery Registry (GBSR). All data are registered prospectively in cooperation with the Institute for Quality Assurance in Surgical Medicine at the Otto-von-Guericke University Magdeburg, Germany. Methods Data are registered in an online database. Data collection on obesity and metabolic surgery is voluntary, and was started in 2005. In addition, follow-up data are collected once a year. Results Since 2005, 8,293 sleeve gastrectomies, 10,330 Roux-en-Y gastric bypass procedures, and 3,741 gastric banding procedures have been performed in Germany, according to the data of the GBSR. Mean age and mean body mass index of female patients with gastric banding, sleeve gastrectomy, or Roux-en-Y gastric bypass were significantly lower than those of male patients. The incidence of relevant comorbidities was significantly higher in male than in female patients. Conclusion Metabolic and obesity surgery is becoming more and more popular in Germany. Data from the GBSR study show significant differences in preoperative comorbidities and postoperative complication and mortality rates between male and female patients. There is a need for further evaluation of gender-specific aspects to optimize patient selection and reduce specific postoperative complications.

Abstract
BACKGROUND Since 1 January 2005, the outcomes of bariatric surgeries have been examined in Germany. All data are registered prospectively in cooperation with the Institute of Quality Assurance in Surgery at Otto-von-Guericke University Magdeburg. METHODS Data are collected in an online data bank. Data collection began in 2005 for the results of gastric banding (GB) and in 2006 for sleeve gastrectomies (SGs). In addition to primary bariatric operations, data regarding the complications of revision procedures and redo operations have been analyzed. Participation in the quality assurance study is required for all certified centers in Germany. RESULTS SGs are a popular redo operation after failed gastric banding. Using the German Bariatric Surgery Registry, we analyzed data from 137 SGs that were used in a one-step approach after GB and 37 SGs that were used in a two-step approach. Leakage rates for primary SGs dropped to 1.9 %. The incidence of leakage after a one-step SG after GB is significantly higher (4.4 %) than for a two-step approach (0 %). CONCLUSION SGs are popular procedures after failed GB in Germany, but the complication rates for one-step band removal are higher than for a two-step approach. After examining the data, we suggest performing band removal and SG as a two-step procedure. Further analysis is necessary to evaluate the optimal time period between band removal and SG. Follow-up investigations must be performed to determine if SG is an effective and safe option after GB.

Abstract
BACKGROUND Identifying factors that influence weight loss after bariatric surgery is one way to predict a successful surgical outcome. Knowledge of the effect of gender on weight loss after bariatric surgery has not been well demonstrated in the literature despite being noted in every day practice. The aim of this study was to find the influence of gender on long-term weight loss after bariatric surgery. METHODS A retrospective analysis of data retrieved from a prospectively maintained bariatric database was conducted. RESULTS The study included 640 consecutive patients. Their mean age was 38 ± 10 years, mean preoperative body mass index was 44.9 ± 8.4 kg/m2, and mean preoperative excess weight (EW %) was 108.3 ± 38.4%. The mean of the average excess weight loss (EWL %) was 43.3 ± 42.4%. Three procedures were utilized: Roux-en-Y gastric bypass (RYGB), vertical banded gastroplasty (VBG), and gastric banding (GB). Both VBG and RYGB induced significantly more EWL % than GB (d = 22.1%, p < 0.001 and d = 16, p = 0.02, respectively). In patients who underwent VBG and GB, males had significantly lower preoperative EW % (Student t = -4.86, p < 0.001, and Student t = 4.69, p < 0.001, respectively), and postoperative mean of the average EWL % (Student t = -2.43, p = 0.016, and Student t = -3.33, p = 0.002, respectively) than females. In patients who underwent RYGB, there were no differences in the preoperative EW % (t = -1.03, p = 0.309) or the mean of the average EWL % (t = 0.406, p = 0.688). The simple linear regression model used to explain the variability in EWL %, accounted for by the variability in the preoperative EW %, was significant (F = 180, p < 0.001). Analysis of the residual errors in predicting the EWL % revealed no significant difference between males and females after VBG and after RYGB (t = 0.117, p = 0.907 and t = 1.052, p = 0.3, respectively), while it was significant after GB (t = -2.999, p = 0.003). CONCLUSION From our experience, we suggest that GB not to be offered as a first choice for obese male patients.

Systematic review on reoperative bariatric surgery: American Society for Metabolic and Bariatric Surgery Revision Task Force. Surg Obes Relat Dis 2014; 10:952-72. [PMID: 24776071 DOI: 10.1016/j.soard.2014.02.014] [Citation(s) in RCA: 239] [Impact Index Per Article: 23.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2014] [Revised: 02/09/2014] [Accepted: 02/10/2014] [Indexed: 02/07/2023]
Abstract
BACKGROUND Reoperative bariatric surgery has become a common practice in many bariatric surgery programs. There is currently little evidence-based guidance regarding specific indications and outcomes for reoperative bariatric surgery. A task force was convened to review the current evidence regarding reoperative bariatric surgery. The aim of the review was to identify procedure-specific indications and outcomes for reoperative procedures. METHODS Literature search was conducted to identify studies reporting indications for and outcomes after reoperative bariatric surgery. Specifically, operations to treat complications, failed weight loss, and weight regain were evaluated. Abstract and manuscript reviews were completed by the task force members to identify, grade, and categorize relevant studies. RESULTS A total of 819 articles were identified in the initial search. After review for inclusion criteria and data quality, 175 articles were included in the systematic review and analysis. The majority of published studies are single center retrospective reviews. The evidence supporting reoperative surgery for acute and chronic complications is described. The evidence regarding reoperative surgery for failed weight loss and weight regain generally demonstrates improved weight loss and co-morbidity reduction after reintervention. Procedure-specific outcomes are described. Complication rates are generally reported to be higher after reoperative surgery compared to primary surgery. CONCLUSION The indications and outcomes for reoperative bariatric surgery are procedure-specific but the current evidence does support additional treatment for persistent obesity, co-morbid disease, and complications.
