Patient expectations of bariatric surgery are gender specific--a prospective, multicenter cohort study

The experiences and informational needs of women electing bariatric surgery: A qualitative content analysis of an online support forum

This study aimed to explore how women leveraged online peer support to discuss their experiences and seek information related to bariatric surgery. Specifically, it sought to determine whether women are adequately prepared for the unique challenges associated with bariatric surgery and identify potential areas for improving preoperative education and support. An online search identified the Bariatric Pal online forum and sub-forum The Gals Room, of which 289 posts were selected and analysed using conventional qualitative content analysis. Five categories were developed: Connection with Forum Community; Life After Bariatric Surgery; Physical Symptoms and Experiences; Healthcare Concerns and Experiences; and Psychological Experiences. The findings highlight gaps in preoperative education for women, particularly regarding reproductive health and emphasise the value of online peer support in coping with and managing chronic health conditions. Further research is needed to inform improvements in preoperative and postoperative support for individuals undergoing bariatric surgery.

Experiences and expectations of patients with obesity 3 months after metabolic and bariatric surgery: a qualitative study

OBJECTIVES

Patients experience significant physical and psychological changes within the first 3 months post-surgery, yet few studies focus on patient experiences during the early postoperative period. This study aimed to explore the patient experiences and expectations for nursing follow-up during the home recovery period following metabolic and bariatric surgery.

DESIGN

A qualitative descriptive study design was used. Participants were selected using a purposive sampling method, and semi-structured interviews were conducted to collect data, which then were analysed using the content analysis method.

SETTING

The study was conducted in a tertiary hospital in eastern China.

PARTICIPANTS

21 patients (8 men and 13 women; aged 18-51 years) who received metabolic and bariatric surgery were included, with 16 within 3 months post-surgery and 5 beyond 3 months.

RESULTS

Four themes emerged: (1) Physical and psychological rehabilitation: patients were enthusiastic and motivated about their physical recovery and mental well-being. (2) Stress and challenges: patients encountered various pressures and challenges, especially in dietary transitions and emotional management. (3) Adjustment and adaptation: patients were committed to managing discomfort and developing healthy dieting strategies through personal effort and diverse support. (4) Expectations for comprehensive support: patients desire comprehensive support and services from healthcare providers.

CONCLUSIONS

Healthcare providers should focus on the early postoperative experiences of patients and deliver personalised health education and emotional support to help them navigate the postoperative adaptation and ultimately achieve long-term health goals.

Patients experience with preoperative use of anti-obesity medications and associations with bariatric surgery expectations

BACKGROUND

Few studies have investigated the use of anti-obesity medications (AOMs) before bariatric surgery and how prior use impacts patients' goals and expectations for surgery.

OBJECTIVES

This study investigated associations between patients' experiences with AOMs and weight loss expectations before bariatric surgery.

SETTINGS

Single tertiary university hospital.

METHODS

Patients were electronically surveyed with a 31-item questionnaire via email or the patient portal with a primary predictor variable of AOMs presurgery. Outcomes included degree of weight loss and weight regain and motivation for seeking surgery.

RESULTS

A total of 346 persons were invited to complete the survey; 112 surveys (32.4%) were completed, with 7 excluded because of not answering the AOM question. 73% reported AOM use. Among those who took AOMs before seeking bariatric surgery, average weight loss was 13 kg (SD 10) corresponding to a 4.4-kg/m2 decrease in BMI. Of past AOM recipients, 87% reported weight regain on stopping AOMs. Average weight regain was 18 kg (SD 13; 126% increase). Patients reported improved longevity and quality of life as motivation for seeking surgery, with AOM use history having no effect. Subjects reported an average weight loss goal of 65.8 kg (39% of baseline weight) from bariatric surgery.

CONCLUSIONS

AOMs were commonly used in those seeking bariatric surgery, but motivation for surgery did not differ by AOM use history. Motivations were most often related to goals for better overall health.

Understanding preferences of patients with obesity for metabolic bariatric surgery: a comprehensive adaptive choice-based conjoint analysis

BACKGROUND

Patient preferences toward metabolic bariatric surgery (MBS) remain inadequately explored.

OBJECTIVE

This study aims to identify and analyze the key factors influencing the decision-making process of patients considering MBS.

SETTING

The research was conducted at the metabolic bariatric surgery clinic of the Medical Research Institute Hospital, Alexandria University, Egypt.

METHOD

Patients with obesity were recruited at the clinic before MBS. The surgical profiles were characterized by attributes including treatment method, recovery and reversibility, treatment tenure, expected weight loss, impact on associated medical problems, risk of complication, side effects, dietary changes, and out-of-pocket costs. Patients engaged in an online survey comprising sociodemographic data, Build Your Own (BYO) section, screening section, and choice tournament section. Adaptive choice-based conjoint analysis was employed to discern the preferences.

RESULTS

Of the 299 respondents, the surgical profiles with the highest preference involved a loss of 80% of excess weight without any recurrence (14.67 [95% CI, 14.10-15.23]), 0% risk of complication (13.74 [95% CI, 13.03-14.45]), and absence of adverse effects (11.32 [95% CI, 10.73-11.91]). K-mean cluster analysis identified 2 distinct groups: "patients prioritize weight loss" group prioritized excess weight loss, surgery availability, and diet change, whereas "patients prioritize avoidance of complications" group focused on the risk of complication, adverse effects, and the surgery mechanism.

CONCLUSIONS

MBS candidates predominantly value weight loss without recurrence, followed by minimization of complication risks and adverse effects, within 3 years postsurgery. Conversely, initial out-of-pocket costs and resolution of medical conditions were deemed the least influential attributes.

Translation and Validation of the Brazilian Version of the European Obesity Academy Questionnaire on Patients' Motivations for Seeking Metabolic and Bariatric Surgery

PURPOSE

Understanding patients' motives for undergoing metabolic and bariatric surgery (MBS) is key to managing postoperative expectations. We aimed to translate and validate the 14-item European Obesity Academy Questionnaire on Expectations about Surgical Treatment (EOAQ-EST) to Brazilian Portuguese for research and clinical use.

MATERIALS AND METHODS

This study included a total of 198 candidates for MBS at a reference academic hospital in Brazil from January 2021 to February 2022. We followed Beaton and Bombardier's guidelines for translation and cultural adaptation, including translation, back-translation, comparative analysis, expert review, pilot testing, and the creation of the final version of the questionnaire. Reliability was tested with McDonald's omega, and internal validity was assessed using confirmatory factor analysis (CFA).

RESULTS

The final version was applied to 161 patients, 85% female, with a mean age of 46.4 ± 10.3 years and a mean BMI of 48.3 ± 8.2 kg/m2. Validity was supported by a bifactorial model (95% CI 0.044-0.104, p = 0.08), excluding one item (improved fertility) due to a floor effect. The reliability analysis showed that the 13 remaining items were internally consistent, with a McDonald's ω of 0.625.

CONCLUSIONS

The Brazilian-Portuguese version of EOAQ-EST proved to be user-friendly, consistent, and reliable. This questionnaire may assist multidisciplinary teams in effectively addressing patients' expectations concerning metabolic and bariatric surgery (MBS) outcomes.

Quantifying patients' expectations prior to bariatric surgery with the BODY-Q in an international multicentre cohort

Many people living with obesity may have unrealistic expectations prior to undergoing bariatric surgery. These expectations can lead to frustration, regret and even worse psychological outcomes after surgery. Prior to undergoing bariatric surgery, patients completed the BODY-Q Expectations scale. This 15-item scale asks patients to imagine what their life will be like when 2 years have passed since bariatric surgery. Scores for expectations range from 0 (low) to 100 (high). Linear regression models were used to assess which of the patient characteristics could predict patients' expectations. From 2019 to 2020, a total of 333 patients were recruited from three different countries. The mean score on the BODY-Q Expectations scale was 73.1, ±20. Out of the 15 items on the Expectation scale, people living with obesity found it most likely that bariatric surgery would make them feel better and improve their energy, while it was reported least likely that they would look good without clothes on. Younger age (p = <.01) and race (non-white) (p = .046) were found to be significant predictors for higher scores on the Expectations scale. Participants who identified as non-white from the Netherlands and United States, and those aged under 40 years reported higher expectations compared with participants who identified as white race and were 40 years of age or older. Prior to bariatric surgery, patients aged under 40 years and those who identified as non-white for race had higher expectations that their life would change after bariatric surgery. These relevant findings should be considered when giving pre-operative counselling.

Women's Reasons to Seek Bariatric Surgery and Their Expectations on the Surgery Outcome - a Multicenter Study from Five European Countries

Purpose

Understanding patients’ reasons for having bariatric surgery and their expectation on surgery outcomes is important to provide the best clinical practice and reduce unrealistic expectations. It is unknown if reasons and expectations differ between countries. We aimed to investigate the reasons for seeking bariatric surgery and expectations of surgical outcomes among patients in five European countries.

Methods

In total, 250 women accepted for bariatric surgery were recruited: 50 women each from Finland, Germany, Norway, Sweden, and the Netherlands. Participants ranked 14 reasons for seeking surgery, and reported the three primary reasons. They also reported expectations on weight loss and impact of surgery vs. lifestyle on weight loss outcomes.

Results

Mean age and body mass index were 42.9 ± 11.5 years and 45.1 ± 6.2 kg/m², respectively. Weight loss and improved co-morbidity were ranked as the most important reasons. Participants expected to lose between 70.8 and 94.3% of their excessive weight. The expected impact of surgery as a driver of weight loss was higher in Germany and the Netherlands compared to in Finland, Norway, and Sweden where participants expected lifestyle changes to also have an impact.

Conclusion

Weight loss and improved co-morbidities were the main reasons for undergoing bariatric surgery. Expectations on weight loss were generally very high, but expectations of surgery vs. lifestyle as the main driver of weight loss differed between countries. While some patients understand the importance of lifestyle change and maintenance of a healthy lifestyle after surgery in order to obtain a successful weight loss, other may need additional counselling.

Desire to lose weight was associated with the adoption of weight control strategies but not healthier lifestyle behaviours among post-bariatric surgery patients: NHANES 2013-2018

The desire to lose weight is presumably high among patients with severe obesity who have undergone bariatric surgery. The purpose of this study is to examine the associations of desire to lose weight with weight control strategies, depressive symptoms and lifestyle behaviours among post-bariatric surgery patients. Participants were adults who participated in the National Health and Nutrition Examination Survey (2013-2018) and self-identified a history of bariatric surgery. The desire to lose weight, weight control strategies, depressive symptoms, physical activity and sitting time were measured by self-report questionnaires. Dietary information was derived from 24-h dietary recalls. The correlates of the desire to lose weight were examined by logistic or linear regressions with appropriate weighting and variance estimation techniques, adjusting for covariates such as length of time post-surgery. Results showed that at a mean of 7.8 (standard deviation [SD] = 0.5) years post-surgery (N = 142), 88.6% of participants wanted to weigh less. The average total energy intake was 1747 (SD = 72) kcal/day with 36.2% (SD = 0.7%) of the energy from total fat; the median total moderate-intensity physical activity was 88.5 min/week; and the mean sitting time was 796.0 (SD = 47.0) min/day. The desire to lose weight was positively associated with the adoption of healthy weight control strategies (odds ratio 17.4, 95% confidence interval 3.5-87.0, p < .01). No other significant associations were observed. Findings highlight the need for studies to improve patients' lifestyle behaviours post-surgery (e.g., reduce fat intake, increase physical activity) and examine the correlates of desire to lose weight in larger samples.

Online survey on factors influencing patients' motivation to undergo bariatric surgery

Given the worldwide increasing prevalence of severe obesity and considering the amount of scientific evidence demonstrating the beneficial effects of bariatric surgery (BS), it is surprising that only a fraction of patients with obesity undergo BS. We therefore conducted an anonymized online survey among individuals with a history of BS to understand factors influencing the deciding process leading to BS. Respondents were recruited on a voluntary basis from obesity-related social media groups between April and June 2020. The self-designed, non-validated questionnaire consisted of 20 questions and was open to any participants with a history of BS. Of 851 participants who started the survey, 665 completed the questionnaire (completion rate of 78.1%). Five years after BS, still 70% of the survey-participants were very satisfied or satisfied with the surgical result. However, the majority (73.3%) would have undergone BS earlier. The main motivation to choose BS was related to health status or quality of life. Important characteristics for a bariatric surgeon to obtain patients' trust are "taking time and listen" (74.7%), empathy (64%) and sympathy (56%). Post-operative satisfaction with the surgical outcome was high and long-lasting in this large cohort of BS patients. However, most participants would retrospectively have undergone BS earlier. The main reason to choose BS as treatment for their obesity were impaired physical health or reduced quality of life. Nearby location to patients' residence and availability of surgeons with empathy were decisive motives for bariatric centre selection.

Impact of preoperative weight loss achieved by gastric balloon on peri- and postoperative outcomes of bariatric surgery in super-obese patients: a retrospective matched-pair analysis

Background

An intragastric balloon is used to cause weight loss in super-obese patients (BMI > 60 kg/m²) prior to bariatric surgery. Whether weight loss from intragastric balloon influences that from bariatric surgery is poorly studied.

Methods

In this retrospective, single-center study, the effects of intragastric balloon in 26 patients (BMI 69.26 ± 6.81) on weight loss after bariatric surgery (primary endpoint), postoperative complications within 30 days, hospital readmission, operation time, and MTL30 (secondary endpoints) were evaluated. Fifty-two matched-pair patients without intragastric balloon prior to bariatric surgery were used as controls.

Results

Intragastric balloon resulted in a weight loss of 17.3 ± 14.1 kg (BMI 5.75 ± 4.66 kg/m²) with a nadir after 5 months. Surgical and postoperative outcomes including complications were comparable between both groups. Total weight loss was similar in both groups (29.0% vs. 32.2%, p = 0.362). Direct postoperative weight loss was more pronounced in the control group compared to the gastric balloon group (29.16 ± 7.53% vs 23.78 ± 9.89% after 1 year, p < 0.05 and 32.13 ± 10.5% vs 22.21 ± 10.9% after 2 years, p < 0.05), who experienced an earlier nadir and started to regain weight during the follow-up.

Conclusion

A multi-stage therapeutic approach with gastric balloon prior to bariatric surgery in super-obese patients may be effective to facilitate safe surgery. However, with the gastric balloon, pre-treated patients experienced an attenuated postoperative weight loss with an earlier nadir and earlier body weight regain. This should be considered when choosing the appropriate therapeutic regime and managing patients’ expectations.

Experiences of the Bariatric Pre-Surgery Evaluation Process in a National Health Service—An Interpretative Phenomenological Analysis

There is currently little understanding of bariatric patients’ experiences and expectations of the bariatric pre-surgery evaluation (PSE) process. This is especially true for patients within the National Health Service (NHS) in the UK. Consequently, this study undertakes a qualitative study to explore the experiences and expectations of the bariatric PSE amongst patients who had undergone bariatric surgery within the NHS in the UK, using the Interpretative Phenomenological Analysis. Three inter-related superordinate themes were presented: (i) ‘PSE was challenging but essential’, (ii) ‘Coping processes to deal with the PSE’, and (iii) ‘Staff and service evaluation’. Most participants had conflicting feelings about the PSE process as it had both positive and negative impacts on their wellbeing. The process was considered essential for preparation and successful post-surgery adjustment, though the uncertainty of approval was experienced as very distressing. Consequently, participants utilised both external and internal coping strategies, such as social support, researching, or ‘toeing the line’. Participants’ experiences encouraged them to provide feedback about the staff and service, which revealed a preference for a tailored evaluation process. The emerged themes represent an initial framework for helping healthcare providers and researchers to involve patients in service delivery thereby facilitating a patient-centred approach. A starting point is to audit patients’ perspectives routinely. Further investigations are needed to better define, validate, and understand constructs and processes identified in this study.

Patient Motivations and Goals for Bariatric Surgery: A Mixed Methods Study

BACKGROUND

Existing research has primarily focused on weight as the outcome of interest for bariatric surgery; however, patients frequently report other lifestyle and interpersonal surgery motivations and goals. Understanding the spectrum of bariatric surgery goals and motivations has important implications for enhancing patient-centered care and surgery outcomes.

OBJECTIVES

The current study characterized the nature of bariatric patient motivations and goals for surgery, described the extent to which motivations matched goals, and examined whether men and women differed in the specific motivations/goals described.

SETTING

Teaching hospital, United States METHODS: Data were obtained via retrospective chart review of bariatric patient responses to the clinic's standard open-ended questions about motivations and goals for bariatric surgery. A mixed method approach was used, including content analysis, to identify themes and χ²/t test analyses to test gender differences.

RESULTS

Surgery motivations and outcome goals were reflected by 8 overarching and overlapping themes. The most common motivations were related to general health and quality of life. The most common goals were to improve health/longevity and mobility. Over a quarter of patients showed no overlap between motivations and goals. Few gender differences were observed.

CONCLUSION

Findings underscore the importance of goals beyond weight loss, as well as the utility of helping patients shape their goals in accordance with goal-setting theories.

Primary and Secondary Nonresponse Following Bariatric Surgery: a Survey Study in Current Bariatric Practice in the Netherlands and Belgium

PURPOSE

Primary nonresponse (1NR) - inability to achieve adequate weight loss after surgery - and secondary nonresponse (2NR) - excessive weight regain after initial adequate weight loss after surgery - can occur in up to 25-35% of patients after bariatric surgery. The aim of this study was to explore the variations in both definition as well as management of 1NR and 2NR amongst bariatric surgeons.

MATERIALS AND METHODS

An online survey was distributed to all members of the national bariatric societies in the Netherlands and Belgium regarding questions about definition, work-up and treatment of 1NR and 2NR after bariatric surgery.

RESULTS

A total of 45 responses from bariatric surgeons were obtained, representing 32 medical centers that perform bariatric procedures. When assessing 1NR, excess weight loss(EWL) was reported to be used by most respondents(30/45), total body weight loss(TBWL) by 18/45 and body mass index(BMI) by 25/45. A great variation in cut off values was observed. When assessing 2NR, percentage weight gain from the lowest (nadir) weight was preferred most by 22/45 respondents with cut off values varying from 5 to 20%. Most respondents deemed 18 months after initial surgery the most appropriate timeframe to determine 1NR or 2NR.

CONCLUSIONS

The current practice regarding primary and secondary nonresponse after bariatric surgery has a wide variety in definitions, work-up and treatment options. Consensus on the definition of 1NR and 2NR is needed to optimize the treatment of bariatric patients.

Outcome expectation and risk tolerance in patients seeking bariatric surgery

BACKGROUND

Average long-term outcome after laparoscopic Roux-en-Y gastric bypass is 25% total weight loss. The risk of short-term complications (leakage and bleeding), acute internal herniation, and mortality are 4.0%, 2.5%, and .2%, respectively. There is a paucity of evidence on what patients expect in terms of weight loss and to what extent surgical risks are tolerated.

OBJECTIVE

To examine the patient's weight loss expectations and acceptance of the morbidity and mortality risk after primary laparoscopic Roux-en-Y gastric bypass.

SETTING

Teaching hospital, Amsterdam, the Netherlands.

METHODS

Two-hundred patients participated in a standardized survey after completion of an extensive multidisciplinary screening, before surgery. Weight loss expectations, naive assessment, and acceptation of risks of morbidity and mortality were addressed with standard gamble methods.

RESULTS

The 200 participants (156 female, 78%) had a mean age of 45.1 years and a mean body mass index of 42.3 kg/m². Weight loss was overestimated by 151 patients (75.5%), and 79 participants (39.5%) were disappointed with the predicted weight loss. Median accepted risks on short-term complications, acute internal herniation, and mortality were 35.8% (interquartile range, 21.0%-58.0%), 25.1% (interquartile range, 15.9%-50.8%), and 4.5% (interquartile range, 1.0%-10.0%), respectively.

CONCLUSION

Patients seeking bariatric surgery seem to have unrealistic weight loss objectives and are willing to accept substantial risks to achieve these goals.

The Edmonton Obesity Staging System Predicts Perioperative Complications and Procedure Choice in Obesity and Metabolic Surgery-a German Nationwide Register-Based Cohort Study (StuDoQ|MBE)

OBJECTIVE

To examine the relationship between Edmonton Obesity Staging System (EOSS) and perioperative complications as well as surgical procedure.

BACKGROUND

The application of EOSS for the selection of patients with obesity is a more comprehensive measure of obesity-related diseases and a predictor of mortality than body mass index (BMI).

METHODS

This was a nationwide cohort study using prospectively inserted data from the German register for obesity and metabolic surgery StuDoQ|MBE. All patients undergoing sleeve gastrectomy (SG), Roux-en Y gastric bypass (RYGB), and one-anastomosis gastric bypass (OAGB) between February 2015 and July 2017 as a primary treatment for severe obesity were included. Data included gender, age, BMI, ASA score, EOSS, early postoperative complications next to the Clavien-Dindo grading system, readmission, and 30-day mortality.

RESULTS

A total of 9437 patients were included. The mean BMI was 49.5 kg/m² ± 7.8 (range 35-103.5). The total postoperative complication rate was 5.3%, with the highest rate in EOSS 3 (7.8%) and 4 (6.8%). Thirty-day mortality was 0.2% with the highest mortality after SG in EOSS 3 (1.16%) and EOSS 4 (0.92%) (p = 0.0068). Crosstabs showed a prevalence of Clavien-Dindo III and IV complications of 3.4% (SG), 3.6% (RYGB), and 1.6% (OAGB) in EOSS 2 (p = 0.0032) and 3.5% (SG), 5.1% (RYGB), and 5.6% (OAGB) in EOSS 3.

CONCLUSION

The highest postoperative complications and mortality occurred in patients with EOSS ≥ 3. SG and OAGB could be the procedure of choice to reduce perioperative morbidity; nevertheless, it has to be in mind that in EOSS ≥ 3, SG has the highest mortality.

A Predictive Model of Weight Loss After Roux-en-Y Gastric Bypass up to 5 Years After Surgery: a Useful Tool to Select and Manage Candidates to Bariatric Surgery

INTRODUCTION

Different factors, such as age, gender, preoperative weight but also the patient's motivation, are known to impact outcomes after Roux-en-Y gastric bypass (RYGBP). Weight loss prediction is helpful to define realistic expectations and maintain motivation during follow-up, but also to select good candidates for surgery and limit failures. Therefore, developing a realistic predictive tool appears interesting.

PATIENTS/METHODS

A Swiss cohort (n = 444), who underwent RYGBP, was used, with multiple linear regression models, to predict weight loss up to 60 months after surgery considering age, height, gender and weight at baseline. We then applied our model on two French cohorts and compared predicted weight to the one finally reached. Accuracy of our model was controlled using root mean square error (RMSE).

RESULTS

Mean weight loss was 43.6 ± 13.0 and 40.8 ± 15.4 kg at 12 and 60 months respectively. The model was reliable to predict weight loss (0.37 < R² < 0.48) and RMSE between 5.0 and 12.2 kg. High preoperative weight and young age were positively correlated to weight loss, as well as male gender. Correlations between predicted weight and real weight were highly significant in both validation cohorts (R ≥ 0.7 and P < 0.01) and RMSE increased throughout follow-up between 6.2 and 15.4 kg.

CONCLUSION

Our statistical model to predict weight loss outcomes after RYGBP seems accurate. It could be a valuable tool to define realistic weight loss expectations and to improve patient selection and outcomes during follow-up. Further research is needed to demonstrate the interest of this model in improving patients' motivation and results and limit the failures.

Predictors of Risk and Success of Obesity Surgery

BACKGROUND

Obesity surgery has proven successful for weight loss and the resolution of comorbidities. There is, however, little evidence on its success and the risk of complications when considering age of onset of obesity (AOO), years of obesity (YOO), preoperative body mass index (BMI), Edmonton obesity staging system (EOSS) score, and age as possible predictors of weight loss, the resolution of comorbidities, and the risk of complications.

METHODS

Patients who underwent Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy (LSG) from a prospective database were analyzed. Multiple regression analyses were used to predict comorbidities and their resolution, percentage excess weight loss (%EWL) and total weight loss (%TWL) 12 months after surgery, and the risk of complications using the predictors AOO, YOO, age, EOSS, and BMI.

RESULTS

180 patients aged 46.8 ± 11.1 years with a preoperative BMI 49.5 ± 7.5 were included. The number of preoperative comorbidities was higher with older age (β = 0.054; p = 0.023) and a greater BMI (β = 0.040; p = 0.036) but was not related to AOO and YOO. Patients with AOO as a child or adolescent were more likely to have an EOSS score of ≥2. Greater preoperative BMI was negatively associated with %EWL (β = -1.236; p < 0.001) and older age was negatively associated with %TWL (β = -0.344; p = 0.020). Postoperative complications were positively associated with EOSS score (odds ratio [OR] 1.147; p = 0.042) and BMI (OR 1.010; p = 0.020), but not with age. AOO and YOO were not related to postoperative outcome.

CONCLUSION

Greater BMI was associated with a lower %EWL and age was associated with a low %TWL. YOO and AOO did not influence outcome. Age, BMI, and EOSS score were the most important predictors for risk and success after obesity surgery. Surgery should be performed early enough for optimal outcomes.

[Bariatric surgery: Expectations and therapeutic goals-a contradiction?]

In the majority of patients with morbid obesity, metabolic/bariatric surgery leads to relevant and sustained weight loss and improves obesity-related comorbidities, quality of life and functionality. Moreover, the associated reduction of risk factors for cardiovascular events and cancerous diseases has been shown to improve life expectations. Due to its excellent antidiabetic effect, the currently valid national S3 guidelines now recommend metabolic/bariatric surgery in patients who have a body mass index (BMI) ≥30 kg/m² with poorly controlled diabetes. The Edmonton staging system enables a multidimensional consideration of the severity grade of obesity for each individual patient independent of the BMI. Patients with relevant obesity-related metabolic comorbidities should be prioritized for treatment and if possible before the occurrence of end-organ damage that is at least in some cases irreversible and which also increases the perioperative risk. Therapeutic goals for each individual patient should be carefully defined preoperatively in order to mediate realistic expectations. Unrealistic expectations, such as "surgery solves my problems", "surgery makes me more beautiful", "surgery eliminates stigma", and "surgery guarantees success", are common in bariatric surgery patients. These unrealistic expectations can lead to frustration and to severe psychological decompensation and need to be addressed as early as possible by an interdisciplinary team. Redundancies, conclusive and empathic communication in the team improve therapy adherence, the expectations and therefore the overall outcome.

Patient perspectives about bariatric surgery unveil experiences, education, satisfaction, and recommendations for improvement

BACKGROUND

Following bariatric surgery, up to 35% of patients struggle with strict regimens and experience weight recidivism within 2 years [1-5]. Accredited weight management centers (WMC) must provide educational programs and support patients in lifestyle changes before and after surgery. Educational programs, however, may not be evidence-based or patient-centered and may vary in curriculum, approach, and educator type [6].

OBJECTIVE

To obtain patient descriptions about the weight loss surgery (WLS) experience, including education, satisfaction, and recommendations for improvement.

SETTING

Participants were recruited from a university hospital-based WMC in Pennsylvania.

METHODS

This qualitative descriptive study used purposive sampling and inductive content analysis.

RESULTS

A NEW ME-VERSION 2.0, encompassed themes from semistructured interviews with 11 participants (36% male). Theme 1: Programming and Tools, explained how individuals undergoing WLS found support through educational programming. Theme 2: Updates and Upgrades, identified issues surrounding quality of life and challenges before and after surgery. Theme 3: Lessons Learned and Future Considerations, identified satisfaction levels and recommendations for improving the WLS experience. Participants reported positive experiences, acknowledging educational programs and extensive WMC resources, yet also offered recommendations for improving educational programming.

CONCLUSION

Patient narratives provided evidence about the WLS experience. Achievement of weight goals, adherence to rules, and improved health status contributed to perceptions of WLS success. Participants encouraged educators to identify expected outcomes of educational programming, monitor holistic transformations, foster peer support, and use technology in WMC programming. Results also validated the need for the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program's education requirement (standard 5.1). Future educational research could help develop best practices in WLS patient education and assess associations between education and clinical outcomes.

Association of Bariatric Surgery vs Medical Obesity Treatment With Long-term Medical Complications and Obesity-Related Comorbidities

IMPORTANCE

The association of bariatric surgery and specialized medical obesity treatment with beneficial and detrimental outcomes remains uncertain.

OBJECTIVE

To compare changes in obesity-related comorbidities in patients with severe obesity (body mass index ≥40 or ≥35 and at least 1 comorbidity) undergoing bariatric surgery or specialized medical treatment.

DESIGN, SETTING, AND PARTICIPANTS

Cohort study with baseline data of exposures from November 2005 through July 2010 and follow-up data from 2006 until death or through December 2015 at a tertiary care outpatient center, Vestfold Hospital Trust, Norway. Consecutive treatment-seeking adult patients (n = 2109) with severe obesity assessed (221 patients excluded and 1888 patients included).

EXPOSURES

Bariatric surgery (n = 932, 92% gastric bypass) or specialized medical treatment (n = 956) including individual or group-based lifestyle intervention programs.

MAIN OUTCOMES AND MEASURES

Primary outcomes included remission and new onset of hypertension based on drugs dispensed according to the Norwegian Prescription Database. Prespecified secondary outcomes included changes in comorbidities. Adverse events included complications retrieved from the Norwegian Patient Registry and a local laboratory database.

RESULTS

Among 1888 patients included in the study, the mean (SD) age was 43.5 (12.3) years (1249 women [66%]; mean [SD] baseline BMI, 44.2 [6.1]; 100% completed follow-up at a median of 6.5 years [range, 0.2-10.1]). Surgically treated patients had a greater likelihood of remission and lesser likelihood for new onset of hypertension (remission: absolute risk [AR], 31.9% vs 12.4%); risk difference [RD], 19.5% [95% CI, 15.8%-23.2%], relative risk [RR], 2.1 [95% CI, 2.0-2.2]; new onset: AR, 3.5% vs 12.2%, RD, 8.7% [95% CI, 6.7%-10.7%], RR, 0.4 [95% CI, 0.3-0.5]; greater likelihood of diabetes remission: AR, 57.5% vs 14.8%; RD, 42.7% [95% CI, 35.8%-49.7%], RR, 3.9 [95% CI, 2.8-5.4]; greater risk of new-onset depression: AR, 8.9% vs 6.5%; RD, 2.4% [95% CI, 1.3%-3.5%], RR, 1.5 [95% CI, 1.4-1.7]; and treatment with opioids: AR, 19.4% vs 15.8%, RD, 3.6% [95% CI, 2.3%-4.9%], RR, 1.3 [95% CI, 1.2-1.4]). Surgical patients had a greater risk for undergoing at least 1 additional gastrointestinal surgical procedure (AR, 31.3% vs 15.5%; RD, 15.8% [95% CI, 13.1%-18.5%]; RR, 2.0 [95% CI, 1.7-2.4]). The proportion of patients with low ferritin levels was significantly greater in the surgical group (26% vs 12%, P < .001).

CONCLUSIONS AND RELEVANCE

Among patients with severe obesity followed up for a median of 6.5 years, bariatric surgery compared with medical treatment was associated with a clinically important increased risk for complications, as well as lower risks of obesity-related comorbidities. The risk for complications should be considered in the decision-making process.

Is there a Reason Why Obese Patients Choose Either Conservative Treatment or Surgery?

BACKGROUND

The effects of bariatric surgery on excess weight loss (EWL) and comorbidities are proven. Still, a significant number of patients prefer conservative therapy (ConsP).

OBJECTIVES

The goal of this study was to examine why ConsP and patients awaiting bariatric surgery (SurgP) choose which therapy, and to define the differences in their expectations.

SETTING

Prospective study, 1 university hospital, 1 general hospital, Germany.

METHODS

ConsP and SurgP were asked to complete a questionnaire. Statistical analysis including all patients and a BMI-matched cohort was performed using the chi-square and Wilcoxon rank-sum test.

RESULTS

Overall, 151 patients participated in this study (50 ConsP, 101 SurgP, 69.4% females). The mean age was 41.1 years (SD ± 12.2 years). ConsP had a significant lower body mass index (BMI, 44.7 kg/m² vs. 49.3 kg/m², p < 0.01). The educational level was significantly higher in ConsP. SurgP suffered significantly more often from depression (21.6% vs. 36.6%, p = 0.02) and joint pain (45.1% vs. 68.7%, p = 0.02). ConsP completed significantly more diets that were supervised by physicians or considered well-structured (56.3% vs. 31.0%, p = 0.04). SurgP considered their chosen therapy a last resort significantly more often (p < 0.01). A BMI-matched analysis between ConsP and SurgP revealed no significant differences in the prevalence of comorbidities but showed that fear of surgery plays a major role in the decision-making processes of obese patients.

CONCLUSION

A higher BMI and a greater prevalence of comorbidities had driven patients to seek a more radical solution for their obesity, i.e., surgery. The BMI-matched analysis suggests that fear of surgery is a relevant factor in why obese patients do not decide to undergo bariatric surgery lightly.

Commissioning guidance for weight assessment and management in adults and children with severe complex obesity

The challenge of managing the epidemic of patients with severe and complex obesity disease in secondary care is largely unmet. In England, the National Institute of Health and Care Excellence and the National Health Service England have published guidance on the provision of specialist (non-surgical) weight management services. We have undertaken a systematic review of 'what evidence exists for what should happen in/commissioning of: primary or secondary care weight assessment and management clinics in patients needing specialist care for severe and complex obesity?' using an accredited methodology to produce a model for organization of multidisciplinary team clinics that could be developed in every healthcare system, as an update to a previous review. Additions to the previous guidance were multidisciplinary team pathways for children/adolescent patients and their transition to adult care, anaesthetic assessment and recommendations for ongoing shared care with general practitioners, as a chronic disease management pathway.

Patient Perspective in Obesity Surgery: Goals for Weight Loss and Improvement of Body Shape in a Prospective Cohort Study

OBJECTIVE

Obesity surgery provides sustainable weight loss, improvement of comorbidities, and improved quality of life (QOL). There is few evidence on the patient perspective and goals. This study compared expected and achieved weight loss, body shape, and QOL.

METHODS

Patients completed the Moorehead-Ardelt QOL questionnaire (MAQOL) and questionnaires on actual and expected weight loss and body shape, comorbidities, and goals of obesity surgery preoperatively and within 24 months postoperatively.

RESULTS

44 patients completed questionnaires pre- and postoperatively. BMI, MAQOL and comorbidities significantly improved postoperatively. Patients' expected weight loss goal corresponded to a postoperative BMI of 32.6 ± 5.6 kg/m2 and was not different from their achieved BMI within 24 months after surgery (33.9 ± 6.3 kg/m2, p = 0.276). Self-reported body shape improved but did not reach preoperatively expected goals. During the weight loss period, patients adapted their weight loss and body shape goals to higher levels. Patients attributed a higher part of their success in weight loss to surgery postoperatively (79.5 ± 22.0 vs. 89.1 ± 18.4%, p = 0.028).

CONCLUSION

Patients lost as much weight as they had expected and later modified the goals to even greater weight loss. Body shape improved but did not reach expected levels. QOL improved independently from weight loss and body shape. Patients attributed successful weight loss predominantly to surgery.

Morbidity and health-related quality of life of patients accessing laparoscopic sleeve gastrectomy: a single-centre cross-sectional study in one province of Canada

Background

In Canada, severe obesity (BMI ≥ 35 kg/m²) affects 5% or 1.2 million adults. Bariatric surgery is the only effective treatment for severe obesity, but the demand for publicly funded procedures is high and capacity limited. Little is known in Canada about the types of patients undergoing these procedures, especially laparoscopic sleeve gastrectomy (LSG). The study objective is to examine the socio-demographic profile, morbidity and HRQoL of patients accessing LSG in one Canadian province.

Methods

Health status and HRQoL were examined in patients (n = 195) undergoing LSG. HRQoL was assessed using the EQ-5D-3L, SF-12v2 and the Impact of Weight on Quality of Life-lite questionnaire.

Results

Mean age and BMI were 44 and 49 kg/m² and most were women (82%). Pre-surgery, comorbidities were sleep apnea (65%), dyslipidemia (48%), hypertension (47%) and osteoarthritis (44%). Patients reported impaired HRQoL with 44-67% reporting problems in mobility, usual activities, pain and anxiety/depression. Physical health was impaired more than mental health. There were few socio-demographic differences between women and men, but significant differences in comorbid conditions such as sleep apnea, dyslipidemia, hypertension and gout exist (p < .05). Women reported fewer problems with self-care (9.5% vs. 25.0%, p < .05), and better overall health (VAS 61.5 vs. 52.0, p < .05) and General Health (39.3 vs. 32.9, p < .05), but greater impairment in self-esteem (27.3 vs. 44.1, p < .01) and sexual life (49.2 vs. 63.6, p < .05).

Conclusions

Before LSG, patients reported significant morbidity and impaired HRQoL. Although baseline characteristics were similar between men and women, gender specific differences were observed in comorbid profile and HRQoL.

Physiologic and psychological gender differences in bariatric surgery

BACKGROUND

Bariatric surgery is a safe and effective treatment for clinically severe obesity, but inequity in male and female utilization is well recognized. Approximately 20% of patients undergoing bariatric surgery are male. This paper aims to describe differences in outcomes by gender and to understand the physiologic and psychological differences that may explain this gender gap.

METHODS

We examined 61,708 patients from the Michigan Bariatric Surgery Collaborative (MBSC) undergoing primary bariatric surgery between 2006 and 2016. Clinical data regarding demographics, comorbidities, and outcomes were compared by gender. Preoperative and 1-year postoperative surveys gathered psychological outcomes.

RESULTS

This cohort was consistent with the national population with approximately 22% male patients. There were several significant differences between males and females at the time of surgery. Males tended to be older, have a higher BMI, be married, have lower self-reported depression scores, and have more comorbidities (all p < 0.05). Postoperatively, males suffered more serious complications than women (2.67 vs. 2.12, respectively, p < 0.05). At 1 year postoperatively, males were significantly more satisfied with their operation despite increased complications, decreased weight loss, and decreased rates of comorbidity resolution as compared to females (all p < 0.05).

CONCLUSIONS

Despite significantly lower weight loss and increased complication rates, males tend to have markedly higher satisfaction and psychological well-being scores than females. To improve outcomes in males, earlier referral to surgery may help to significantly reduce their risk. Conversely, increased attention to psychological support in the perioperative period for females may lead to improved psychological outcomes (i.e., body image, depression, psychological well-being).

[The way from cost approval to bariatric surgery : Analysis of resource utilization in a maximum care hospital]

BACKGROUND

Morbid obesity is a medical and economic challenge. Patients who have the indications for bariatric surgery face a long way from the first visit until surgery and a high utilization of resources is required.

OBJECTIVES

The present study aimed to evaluate labor costs and labor time required to supervise obese patients from their first visit until preparation of a bariatric report to ask for cost acceptance of bariatric surgery from their health insurance. In addition, the reasons for not receiving bariatric surgery after receiving cost acceptance from the health insurance were evaluated.

MATERIAL AND METHODS

Patients who had indications for bariatric surgery according to the S3 guidelines between 2012 and 2013, were evaluated regarding labor costs and labor time of the process from the first visit until receiving cost acceptance from their health insurance. Furthermore, body mass index (BMI), age, sex, Edmonton Obesity Staging System (EOSS) stage and comorbidities were evaluated. Patients who had not received surgery up to December 2015 were contacted via telephone to ask for the reasons.

RESULTS

In the present study 176 patients were evaluated (110 females, 62.5%). Until preparation of a bariatric report the patients required an average of 2.7 combined visits in the department of surgery with the department of nutrition, 1.7 visits in the department of psychosomatic medicine, 1.5 separate visits in the department of nutrition and 1.4 visits in the department of internal medicine. Average labor costs from the first visit until the bariatric survey were 404.90 ± 117.00 euros and 130 out of 176 bariatric reports were accepted by the health insurance (73.8%). For another 40 patients a second bariatric survey was made and 20 of these (50%) were accepted, which results in a total acceptance rate of 85.2% (150 out of 176). After a mean follow-up of 2.8 ± 1.1 years only 93 out of 176 patients had received bariatric surgery (53.8%). Of these 16 had received acceptance of surgery by their health insurance only after a second bariatric survey.

CONCLUSION

A large amount of labor and financial resources are required for treatment of obese patients from first presentation up to bariatric surgery. The cost-benefit calculation of an obesity center needs to include that approximately one half of the patients do not receive surgery within more than 2.5 years.
