Long-term follow-up of disease-specific quality of life after bariatric surgery

Impact on Mid-Term Health-Related Quality of Life after Duodenal Switch: a Systematic Review and Meta-Analysis

PURPOSE

Metabolic and bariatric surgery (MBS) could improve health-related quality of life (HrQoL) for selected patients with obesity. Although biliopancreatic diversion with duodenal switch (BPD-DS) is regarded as the most effective MBS technique in achieving weight loss, no consensus has been reached on the impact of BPD-DS on HrQoL. The aim of this meta-analysis is to assess the mid-term HrQoL after BPD-DS in the management of patients with obesity.

MATERIALS AND METHODS

Cochrane, Embase, APA PsycInfo, PubMed, Scopus, and Web of Science were searched for articles from their inception to August 2022 by two independent reviewers using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) system. The review was registered prospectively with PROSPERO (CRD42022352073).

RESULTS

From 223 studies screened, twelve studies met the eligibility criteria, with a total of 937 patients with obesity undergoing BPD-DS. Minimal clinically important differences (MCID) were reached for the physical component summary score (PCS) of the 36-Item Short-Form Health Survey (SF-36) (MD = 13.4) and impact of weight on quality of life (IWQOL)-Lite total score (MD = 48.7). Similarly, MCIDs were attained in the Laval questionnaire and SF-36 subscales.

CONCLUSION

Our meta-analysis demonstrated an improvement in mid-term HrQoL after BPD-DS. Despite the promising trends demonstrated in this meta-analysis, further studies with large sample sizes are needed to evaluate the impact of HrQoL on patients with obesity after BPD-DS.

Psychological Aspects of Treatment with Intragastric Balloon for Management of Obesity: A Systematic Review of the Literature

INTRODUCTION

Optimizing maintenance of weight loss for people with obesity following intragastric balloon (IGB) therapy hinges on the degree to which health care providers can recognize both the impact of emotional problems and mood difficulties on their capacity to self-manage, and requirements for additional support. However, there is limited research on the psychological correlates of IGB therapy. This systematic review, for the first time, attempts to identify and synthesize the empirical evidence for the reciprocal influence between psychological variables and IGB outcomes.

METHODS

A literature search was performed in the PubMed, SCOPUS, MEDLINE, and Google Scholar databases. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed using rigorous inclusion criteria and screening by at least 2 reviewers. The selected articles were assessed for quality using the Strengthening the Reporting of Observational Studies Epidemiology (STROBE) checklist. Data were extracted to address the review aims and presented as a narrative synthesis. The review protocol was preregistered (Prospero CRD42019121291).

RESULTS

A total of 16,179 titles, 14,369 abstracts, and 51 full-text articles were screened, of which 16 studies were included. Findings suggest that female gender, older age, basic educational level, and single/divorced civil status, together with lower levels of depression, binge eating, higher perceived quality of life, and motivation to change were predictors of enhanced IGB treatment outcomes. Dissatisfaction with treatment was higher in those with impaired obesity-related social-life difficulties. The IGB treatment was effective in reducing weight and improving depression, anxiety, eating disorder symptoms, and the overall life quality of patients with obesity - mainly within 6 months from the device positioning and in conjunction with conventional therapies.

DISCUSSION/CONCLUSION

In line with the available literature on obesity and bariatric surgery interventions, poor mental health appears to be an important barrier for successful weight loss among patients with obesity undergoing IGB treatment. In order to improve the efficacy and effectiveness of the IGB therapy, more comprehensive and standardized studies are needed to provide insight into the psychological mechanisms maintaining weight management issues.

Changes in Work Ability after Weight-Loss Surgery: Results of a Longitudinal Study of Persons with Morbid Obesity before and after Bariatric Surgery

INTRODUCTION

Bariatric surgery is a life-changing treatment, but knowledge of its influence on changes in work ability is still limited. We hypothesized that self-reported work ability improves in response to surgery-induced weight loss and sociodemographical variables (e.g., age, sex, and marital status), and that psychosocial characteristics (e.g., depressive symptoms and dysfunctional eating) may have predictive value as to patients' work ability.

METHODS

A total of 200 participants scheduled for bariatric surgery were recruited between September 2015 and June 2018. They completed several self-report measures at the preoperative examination (t1) and at 6- (t2) and 12 months (t3) after bariatric surgery. A repeated-measures analysis of variance was calculated to detect any changes in the work ability and body mass index (BMI) among the 3 time points. Further, a hierarchical multiple regression analysis was used to determine whether any demographical and psychosocial characteristics at (t1) would predict work ability at (t3).

RESULTS

Participants (82% of whom were women) were middle-aged and showed a BMI of nearly 46 at the preoperative medical examination. Excess weight loss at (t2) and at (t3) was 49 and 66%, respectively. Work ability increased toward a moderate level after weight-loss surgery. Work ability and dysfunctional eating at (t1) showed significant predictive value with respect to work ability at (t3).

DISCUSSION

The results suggest that weight-loss surgery has a positive impact on work ability, and indicate a predictive value for the extent of weight loss and dysfunctional eating behavior. Against our hypothesis and in contrast to former research, a predictive value for depressive symptoms and age was not revealed. Further research must show how interventions can support and maintain improvements in work ability after bariatric surgery, in order to reduce sick leave and unemployment in patients with preoperative morbid obesity.

Changes in Patients' Relationship Satisfaction After Weight Loss Surgery: Results of a Study of Persons with Morbid Obesity and Their Relationship Satisfaction Before and 1 Year After Bariatric Surgery

OBJECTIVE

Bariatric surgery is a life-changing treatment, but knowledge of its influence on changes in relationship satisfaction (RS) is still limited. The present study examines whether a patient's RS changes after having bariatric surgery, in response to the surgery-induced weight loss. The predictive value of further variables such as age and sex are also investigated.

METHODS

A total of 145 participants scheduled for bariatric surgery were recruited between September 2015 and June 2018. RS was assessed with a reliable and valid short form of a standardized self-report measure, which was completed before, 6 months and 12 months after surgery.

RESULTS

Loss of excess weight at 6 and 12 months post-surgery was 49% and 66.3%, respectively. The repeated measures ANOVA for the factor "PFB-K" revealed a statistically significant effect, with F (2, 288) = 7.40, p = .001, and η2 = .05, and for the factor "BMI" with F (2, 288) = 505.99, p < .001, and η2 = .78. The highest mean RS score was observed 6 months post-surgery. Sex showed a statistical trend of influence on RS: F (1, 143) = 3.24, p = .074, and η2 = .022. At all three measurement points, men showed higher mean RS scores than women.

CONCLUSION

Bariatric surgery leads to significant weight loss and indicates an increase in RS. While a correlation with the amount of weight lost remains unclear, a trend was seen towards higher RS in subjects with higher weight loss. Men in particular reported higher RS.

Neurocognitive and Psychopathological Predictors of Weight Loss After Bariatric Surgery: A 4-Year Follow-Up Study

Twenty to thirty percent of patients experience weight regain at mid and long-term follow-up. Impaired cognitive functions are prevalent in people suffering from obesity and in those with binge eating disorder, thereby, affecting the weight-loss outcomes. The aim of our study was to investigate neurocognitive and psychopathological predictors of surgical efficacy in terms of percentage of excess weight loss (%EWL) at follow-up intervals of one year and 4-year. Psychosocial evaluation was completed in a sample of 78 bariatric surgery candidates and included psychometric instruments and a cognitive battery of neuropsychological tests. A schedule of 1-year and 4-year follow-ups was implemented. Wisconsin Sorting Card Test total correct responses, scores on the Raven's Progressive Matrices Test, and age predicted %EWL at, both, early and long-term periods after surgery while the severity of pre-operative binge eating (BED) symptoms were associated with lower %EWL only four years after the operation. Due to the role of pre-operative BED in weight loss maintenance, the affected patients are at risk of suboptimal response requiring ongoing clinical monitoring, and psychological and pharmacological interventions when needed. As a result of our findings and in keeping with the latest guidelines we encourage neuropsychological assessment of bariatric surgery candidates. This data substantiated the rationale of providing rehabilitative interventions tailored to cognitive domains and time specific to the goal of supporting patients in their post-surgical course.

Impact of Pre-operative Aerobic Exercise on Cardiometabolic Health and Quality of Life in Patients Undergoing Bariatric Surgery

OBJECTIVE

Examine the effect of aerobic exercise (EX) combined with standard medical care (SC) (EX + SC) compared to SC alone on cardiometabolic health and quality of life in relation to surgical outcomes.

METHODS

Patients receiving bariatric surgery were match-paired to 30 days of pre-operative SC (n = 7, 1 male, 39.0 ± 5.3 years, body mass index 46.4 ± 3.0 kg/m2; low calorie diet) or EX + SC (n = 7, 0 males, 45.6 ± 4.8 years, body mass index 43.9 ± 4.2 kg/m2; walking 30 min/day, 5 days/week, 65-85% HR peak ). Body mass, waist circumference, cardiorespiratory fitness (VO2peak), high sensitivity C-reactive protein (hs-CRP), cytokeratin 18 (CK18), weight related quality of life (QoL), and a 120 min mixed meal tolerance test (MMTT) was performed to assess arterial stiffness via augmentation index normalized to a heart rate of 75 beats per minute (AIx@75), whole-body insulin sensitivity, and glucose total area under the curve (tAUC) pre- and post-intervention (∼2 days prior to surgery). Length of hospital stay (admission to discharge) was recorded.

RESULTS

EX + SC had a greater effect for decreased intake of total calories (P = 0.14; ES = 0.86) compared to SC, but no change in body weight or waist circumference was observed in either group. EX + SC had a greater effect for increased VO2peak (P = 0.24; ES = 0.91) and decreased hs-CRP (P = 0.31; ES = 0.69) compared to SC. EX + SC reduced circulating CK18 (P = 0.05; ES = 3.05) and improved QoL (P = 0.02) compared to SC. Although EX + SC had no statistical effect on arterial stiffness compared to SC, we observed a modest effect size for AIx@75 tAUC (P = 0.36; ES = 0.52). EX + SC had a significantly shorter length of hospital stay (P = 0.05; ES = 1.38) than SC, and a shorter length of hospital stay was associated with decreased sugar intake (r = 0.55, P = 0.04). Decreased AIx@75 tAUC significantly correlated with improved whole-body insulin sensitivity (r = -0.59, P = 0.03) and glucose tAUC (r = 0.57, P = 0.04).

CONCLUSION

EX with SC for 30 days prior to bariatric surgery may be important for cardiometabolic health, quality of life, and surgical outcomes in the bariatric patient.

Quality of Life 10 Years After Bariatric Surgery

PURPOSE

Improvement of the quality of life after bariatric surgery is an important outcome of the treatment. Assessing the long-term QoL results provides better insights into the effectiveness of bariatric surgery.

MATERIALS AND METHODS

This is a cohort study including patients who underwent bariatric surgery between June 2009 and May 2010 in one academic center. Patients underwent either laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric bypass (LRYGB). Overall, 34 patients underwent LSG (52.3%) and 31 patients underwent LRYGB (47.7%). Preoperatively, and after 1 and 10 years, QoL was assessed using two standardized questionnaires: SF-36 and MA-QoLII. After 10 years, 72% of patients filled out these questionnaires.

RESULTS

The global QoL score before surgery was 48.3 ± 20.6. At the 1-year follow-up, the global total QoL score was 79.7 ± 9.8. At the 10-year follow-up, the global total QoL score was 65.1 ± 21.4. There was a significant increase in total QoL between measurements before the operation and 10 years after surgery in the whole study group (p = 0.001) and for patients who underwent LSG (p = 0.001). There was no significant difference between total QoL prior to surgery and 10 years after for patients who underwent LRYGB (p = 0.450).

CONCLUSION

LSG led to significant improvement in QoL.

Weight loss and quality of life after bariatric surgery: a 2-year longitudinal study

BACKGROUND

Bariatric surgery is currently recognized as being an effective technique for weight loss and the improvement of patients' postoperative well-being.

OBJECTIVES

The objective of the study was to measure changes in quality of life (QoL) and body mass index (BMI) according to patients' sex and 2 types of surgical procedures.

SETTING

Longitudinal cohort study using an online platform from a private hospital in West France.

METHODS

Two hundred six patients (38 men and 168 women) undergoing one-anastomosis gastric bypass or sleeve gastrectomy surgery provided online information concerning their QoL and weight both before the operation and then every 3 months over a postoperative period of 24 months.

RESULTS

BMI clinically decreased on average by 19.6% in the first 3 months and up to 39.2% 24 months after surgery. Slight differences between men and women appeared as from 18 months after the operation, with men experiencing increased BMI between 18 and 24 months, contrary to women whose BMI remained unchanged during the same period. QoL also improved significantly. The average level of women's quality of life increased between 3 and 15 months after surgery, then decreased between 15 and 24 months. As for men, no change was observed in their improved QoL between 3 and 24 months after the operation.

CONCLUSIONS

This study highlights the importance of optimizing patients' monitoring, notably around 15 to 18 months after bariatric surgery. This period can be identified as a first "critical" period during which weight regain (especially for men) and diminished self-perceived quality of life (especially for women) appear.

Ten Years After Bariatric Surgery: Bad Quality of Life Promotes the Need of Psychological Interventions

Background: This study aims to evaluate long-term quality of life (QoL) and primary clinical outcomes, 10 years after biliointestinal bypass (BIB) surgery. It was expected that, although BIB might show encouraging primary outcomes, long term QoL could be significantly impaired. Methods: Ninety patients were contacted for a phone interview [age 41.0 ± 10.6 (mean ± SD) years, age-range 31-65 years]. QoL (by SF-36) and the clinical situation (by ad hoc questionnaire) were collected. Data were analyzed with SPSS 22. SF-36 scores were compared with Italian normative data from general and healthy population. We also compared primary clinical outcomes and SF-36 scores between patients who reported high and low levels of satisfaction with BIB. Results: Considering SF-36 results, patients showed significant impairments in QoL compared to general and healthy populations. Sixty-five percent would repeat the BIB. All patients showed at least one chronic adverse event. It occurred a significant decrease in pre-post co-occurrence rates of diabetes (χ2 = 18.41; p < 0.001) and hypertension (χ2 = 50.27; p < 0.001). Large and significant weight loss indexes (i.e., percent excess weight loss (%EWL); body mass index) were observed between pre-post intervention. Conclusion: BIB showed promising primary clinical outcomes (i.e., hypertension, diabetes, and weight loss). However, subjects reported a significant impairment in all SF-36 domains. Ad hoc psychological interventions should be implemented to ameliorate the quality of life of these patients.
