Cognitive-Behavioral Therapy for Postbariatric Surgery Patients With Mental Disorders: A Pilot Study

The effectiveness of an online video-based group schema therapy in improvement of the cognitive emotion regulation strategies in women who have undergone bariatric surgery

BACKGROUND

Adaptive cognitive emotion regulation (CER) strategies toward eating play a very important role in obesity and according to schema therapy, patients with obesity learn that don't respond to their emotional stimuli by eating. Thus, this study aimed to evaluate the effectiveness of an online video-based group schema therapy in improvement of the CER strategies and body mass index (BMI) in women who had undergone bariatric surgery.

METHODS

Forty women who had undergone sleeve gastrectomy were selected and randomly divided into two groups of control and experimental. The experimental group received 10 weekly 90-min sessions of group schema therapy, the control group did not receive any intervention at all. Both groups completed the CER strategies questionnaire during pre-test, post-test and follow-up stages, and the data were analyzed using a multivariate analysis of covariance (MANCOVA) through SPSS software (version 20).

RESULTS

Our results indicated that the experimental group demonstrated significantly higher adaptive CER strategies (P = 0.0001, F = 31.15) and significantly lower maladaptive CER strategies (P = 0.001, F = 9.42), significantly lower BMI (P = 0.001, F = 23.48), as compared to the control condition, following the group schema therapy after the follow-up stage.

CONCLUSION

The findings demonstrated that group schema therapy could lead to an increases in adaptive CER strategies and a decrease in maladaptive CER strategies and BMI in women who had undergone bariatric surgery.

Virtual Reality as a Surgical Care Package for Patients Undergoing Weight Loss Surgery: A Narrative Review of the Impact of an Emerging Technology

While bariatric surgery is regarded as the most effective treatment for people with severe and morbid obesity, its pathway is regarded as a complex one due to the multidisciplinary approaches required from pre-surgery education until long-term management. This is essential to maintain weight loss and improve the quality of life after bariatric surgery. Although these approaches are broadened, patient education, pre-operative preparation, behavioural therapy, rehabilitation, and dietary changes are regarded as the main domains in such complex care. With the increase in technological adaptation in medical services, virtual reality (VR) has shown many benefits that can be utilized in the care of bariatric patients undergoing surgery. However, VR has not been innovated to be a multidomain care package in which bariatric patients could benefit throughout their journey from the pre-operative optimization, recovery, and long-term follow-up. This review aims to give a brief description of some of the applications of VR technology and question whether it has the potential to be considered as a virtual ecosystem to improve the bariatric patients’ experience and pathway throughout surgery and follow-up.

Management of Weight Regain Following Bariatric Surgery: Behavioral Intervention and Pharmacotherapy

INTRODUCTION

Bariatric surgery is the most effective intervention currently available for significant and durable weight loss, but weight regain after surgery is not uncommon. This paper focuses on updates in behavioral interventions and pharmacotherapy to combat weight regain after bariatric surgery.

AREAS COVERED

This paper critically reviews both prospective and retrospective studies assessing pharmacotherapy in post-bariatric surgical patients published within the past 5 years. It also evaluates updates in behavioral therapies and delivery of the therapies in this patient population.

EXPERT OPINION

Weight regain after bariatric surgery is common. Patients who experience weight regain should be evaluated and treated by a multidisciplinary team. Antiobesity pharmacotherapy should be considered for those who qualify as an adjunct to lifestyle modifications, along with behavioral interventions such as cognitive behavioral therapy.

Factors Related to Weight Loss Maintenance in the Medium-Long Term after Bariatric Surgery: A Review

Despite bariatric surgery being the most effective treatment for obesity, some individuals do not respond adequately, especially in the long term. Identifying the predictors of correct weight maintenance in the medium (from 1 to 3 years after surgery) and long term (from 3 years and above) is of vital importance to reduce failure after bariatric surgery; therefore, we summarize the evidence about certain factors, among which we highlight surgical technique, psychological factors, physical activity, adherence to diet, gastrointestinal hormones or neurological factors related to appetite control. We conducted a search in PubMed focused on the last five years (2015–2021). Main findings are as follows: despite Roux-en-Y gastric bypass being more effective in the long term, sleeve gastrectomy shows a more beneficial effectiveness–complications balance; pre-surgical psychological and behavioral evaluation along with post-surgical treatment improve long-term surgical outcomes; physical activity programs after bariatric surgery, in addition to continuous and comprehensive care interventions regarding diet habits, improve weight loss maintenance, but it is necessary to improve adherence; the impact of bariatric surgery on the gut–brain axis seems to influence weight maintenance. In conclusion, although interesting findings exist, the evidence is contradictory in some places, and long-term clinical trials are necessary to draw more robust conclusions.

Bariatric and Cosmetic Surgery in People with Eating Disorders

Rates of eating disorders (EDs) are increasing in Australia, as are rates of bariatric and cosmetic surgery including weight-related procedures. It is known that binge eating disorder (BED) is common in bariatric surgery candidates and that people with EDs are likely to undergo weight-related cosmetic procedures, however, most of the literature is based on clinic samples and focuses on young women and BED. Aims of this study were to determine the prevalence of (1) actual or intended bariatric surgery and (2) actual or intended cosmetic surgery including weight-related procedures in people with a current ED and a lifetime history of BED or bulimia nervosa (BN), and the associations with actual or intended bariatric or cosmetic surgery and demographic features. Using a general population survey, 2977 individuals were interviewed regarding sociodemographic status, ED symptoms, mental health-related quality of life (MHRQoL) and actual or intended use of bariatric and cosmetic surgery, prevalence estimates of which were 2.0% and 1.1%, respectively. People who had planned or received either type of surgery were more likely to be (1) women and (2) have a higher BMI, (3) poorer MHRQoL and (4) a current ED, lifetime BN or BED or features of EDs (all p < 0.05). Age and household income were not significantly associated with increased use of either type of surgery. Given the potential for an ED to affect outcomes of surgery, screening and treatment for EDs should be considered in such surgical candidates.

The Clinical Obesity Maintenance Model: A Theoretical Framework for Bariatric Psychology

Ranked highly in its association with serious medical comorbidities, obesity, a rapidly growing epidemic worldwide, poses a significant socio-economic burden. While bariatric procedures offer the most efficacious treatment for weight loss, a subset of patients risk weight recidivism. Due to the heterogeneity of obesity, it is likely that there are phenotypes or sub-groups of patients that require evidence-based psychological support to produce more sustainable outcomes. So far, however, characteristics of patients have not led to a personalized treatment algorithm for bariatric surgery. Maintenance of weight loss following bariatric surgery requires long-term modification of eating behaviors and physical activity. A recent Clinical Obesity Maintenance Model (COMM) proposed a conceptual framework of salient constructs, including the role of habit, behavioral clusters, emotion dysregulation, mood, health literacy, and executive function as interconnected drivers of obesity maintaining behaviors relevant to the field of bariatric psychology. The primary aim of this concise review is to bring together emerging findings from experimental and epidemiological studies relating to the COMM constructs that may inform the assessment and follow up of bariatric surgery. We also aim to explain the phenotypes that need to be understood and screened prior to bariatric surgery to enable better pre-surgery intervention and optimum post-surgery response.
