Liraglutide for the Treatment of Weight Regain After Bariatric Surgery: A Systematic Review and Meta-analysis

INTRODUCTION

The efficacy of liraglutide for treating type 2 diabetes mellitus and obesity is well established, but their role in the treatment of weight regain after bariatric surgery remains unclear.

METHODS

We searched PubMed, Embase, and Cochrane Library databases in January 2024. A random-effects model was employed to compute mean differences (MD) and events per 100 observations with 95% confidence intervals (CI) for continuous and binary endpoints. Statistical analysis was performed using R software.

RESULTS

A total of 16 studies were included and 881 individuals. Patients were mostly female (50%), aged 36 to 55 years, with a mean body mass index (BMI) of 39.4 kg/m2, and had BS surgery 5 years prior. Over a mean follow-up time ranging from 3 months to 4 years, it was observed a statistically significant reduction in BMI (MD - 8.56 kg/m2; 95% CI 3.34 to 13.79; p < 0.01) and a mean reduction in total weight (MD - 16.03 kg; 95% CI 0.03 to 32.02; p = 0.05) after liraglutide use. Additionally, 65% of patients undertaking liraglutide showed total body weight loss (BWL) above 5% (65.8 events per 100 observations; 95% CI 54.96 to 75.20; p < 0.01), while 26% lost more than 10% of total BWL (26.77 events per 100 observations; 95% CI 19.17 to 36.02; p < 0.01). A limitation is a variability between the studies.

CONCLUSIONS

Our findings support the use of liraglutide for weight management in patients who experience weight regain after BS. Liraglutide is well tolerated and promotes significant weight loss, providing clinicians with a therapeutic option for this clinical challenge.

Long-term changes in body image after bariatric surgery: An observational cohort study

BACKGROUND

While body image improves in the first few months after surgery, data on long-term changes in body image after bariatric surgery are scarce and contradictory.

METHODS

We assessed body image through the Stunkard Figure Rating Scale and the Multidimensional Body-Self Relations Questionnaire-Appearance Scale, which measures appearance evaluation and orientation, overweight preoccupation, and self-classified weight. Surveys were conducted before surgery and at regular intervals until 5 years after bariatric surgery.

RESULTS

61 patients were included in the study. No patients were lost to follow-up until 18 months after bariatric surgery. At 5 years, there were 21 patients (34%) lost to follow-up. We detected an overall improvement in body image until 12-18 months post-surgery. Scores declined after 5 years post-surgery but were still higher than preoperative evaluations. Overweight preoccupation did not change throughout the follow-up period. There was a positive correlation between body weight lost and appearance evaluation. There was also a positive correlation between weight loss and the Body Areas Satisfaction Scale. There was a negative correlation between weight loss and overweight preoccupation. Appearance orientation and self-classified weight were not correlated with weight loss.

CONCLUSIONS

Body image improved after bariatric surgery but was not maintained for all 5 years after surgery.

Quality of Life after Bariatric Surgery-A Systematic Review

Background: Most studies analyzing the health-related quality of life (HRQOL) after bariatric treatment ceased at five years post-surgery or even earlier, and it is unclear whether the HRQOL benefit persists for a longer time. This paper reviews sparse evidence regarding HRQOL in patients who underwent bariatric surgery at least nine years prior. Materials and Methods: A of PubMed, Scopus and Google Scholar between 2007–2021 was carried out for the studies investigating HRQOL as an outcome measure in patients after bariatric surgery of any type and having at least a 9-year follow-up. Inconsistent reporting of weight loss or postgraduate study results unrelated to QoL were not included in the study. The study used the PICO procedure. Results: The review of 18 identified publications demonstrated that bariatric treatment seems to provide a persistent benefit in terms of HRQOL, especially its physical component score. Due to psychological predispositions, some patients appear to be less likely to benefit from bariatric treatment, whether in terms of HRQOL or bodyweight reduction. Inconsistent and imprecise studies may limit the evidence included in a review. Conclusions: The early identification of such patients and providing them with holistic care, including psychological intervention, would likely further improve the outcomes of bariatric treatment.

The complexity of body image following bariatric surgery: a systematic review of the literature

Poor body image is common among individuals seeking bariatric surgery and is associated with adverse psychosocial sequelae. Following massive weight loss secondary to bariatric surgery, many individuals experience excess skin and associated concerns, leading to subsequent body contouring procedures. Little is known, however, about body image changes and associated features from pre-to post-bariatric surgery and subsequent body contouring. The objective of the present study was to conduct a comprehensive literature review of body image following bariatric surgery to help inform future clinical research and care. The articles for the current review were identified by searching PubMed and SCOPUS and references from relevant articles. A total of 60 articles examining body image post-bariatric surgery were identified, and 45 did not include body contouring surgery. Overall, there was great variation in standards of reporting sample characteristics and body image terms. When examining broad levels of body image dissatisfaction, the literature suggests general improvements in certain aspects of body image following bariatric surgery; however, few studies have systematically examined various body image domains from pre-to post-bariatric surgery and subsequent body contouring surgery. In conclusion, there is a paucity of research that examines the multidimensional elements of body image following bariatric surgery.

A Concept Analysis of Disturbed Body Image in Bariatric Surgery Patients

PURPOSE

This article describes the concept of disturbed body image in bariatric surgery patients.

METHOD

Walker and Avant's (2011) method of concept analysis is used in this study.

FINDINGS

After bariatric surgery, the patient's body may change more rapidly than their allocentric ("inside, lived") view of themselves, leading to physical and psychosocial sequelae.

CONCLUSION

If not prepared physically and psychologically for body image challenges after bariatric surgery, patients may experience disturbed body image in the postoperative phase.

IMPLICATIONS FOR NURSING PRACTICE

Understanding the concept of disturbed body image in postoperative bariatric surgery patients may allow health providers to provide preoperative teaching and preparation, as well as postoperative interventions to create congruence between the patient's internal and external selves.

Laparoscopic Adjustable Gastric Band Slippage Rates Following Laparoscopic Gastric Band Insertion: a Single Centre Experience

INTRODUCTION

Laparoscopic adjustable gastric bands (LAGB) are placed around the superior aspect of the stomach to aid weight loss and co-morbidity resolution in morbidly obese patients. Slippage of the LAGB from its original position to lower in the fundus of the stomach leads to gastric obstruction, and sometimes ischaemia or perforation, necessitating LAGB repositioning or removal. This study aimed to identify the incidence of LAGB slippage, as well as predisposing factors that may influence its development.

METHODS

All LAGBs inserted at one centre, via a pars flaccida technique, by four Bariatric specialist consultants, were reviewed utilising a prospectively maintained Bariatric database, computer records and case notes review.

RESULTS

Seven hundred nineteen LAGBs were inserted and 33 slips treated; however, only 22 slips had their LAGB inserted at our centre (local slip rate 3.1 %). Multivariate analysis demonstrated a significant association between LAGB slip and younger median age at LAGB insertion (41 years slip vs. 45 years non-slip; p = 0.027), higher median total excess weight loss (64 % slip vs. 36 % non-slip; p < 0.001) and higher mean excess weight loss per month (2.41 % slip vs. 1.00 % non-slip; p < 0.001). There was no significant effect by sex, BMI at insertion or band type.

CONCLUSIONS

Band slips are associated with greater excess weight loss and younger age. Larger studies may be necessary to further elucidate the risk factors contributing to, and mechanisms of, band slippage.

Psychological outcome 4 years after restrictive bariatric surgery

Extreme obesity is associated with severe psychiatric and somatic comorbidity and impairment of psychosocial functioning. Bariatric surgery is the most effective treatment not only with regard to weight loss but also with obesity-associated illnesses. Health-related psychological and psychosocial variables have been increasingly considered as important outcome variables of bariatric surgery. However, the long-term impact of bariatric surgery on psychological and psychosocial functioning is largely unclear. The aim of this study was to evaluate the relationship between the course of weight and psychological variables including depression, anxiety, health-related quality of life (HRQOL), and self-esteem up to 4 years after obesity surgery.By standardized questionnaires prior to (T1) and 1 year (T2), 2 years (T3), and 4 years (T4) after surgery, 148 patients (47 males (31.8 %), 101 females (68.2 %), mean age 38.8 ± 10.2 years) were assessed.On average, participants lost 24.6 % of their initial weight 1 year after surgery, 25.1 % after 2 years, and 22.3 % after 4 years. Statistical analysis revealed significant improvements in depressive symptoms, physical dimension of quality of life, and self-esteem with peak improvements 1 year after surgery. These improvements were largely maintained. Significant correlations between weight loss and improvements in depression, physical aspects of HRQOL (T2, T3, and T4), and self-esteem (T3) were observed.Corresponding to the considerable weight loss after bariatric surgery, important aspects of mental health improved significantly during the 4-year follow-up period. However, parallel to weight regain, psychological improvements showed a slow but not significant decline over time.

Mechanisms responsible for excess weight loss after bariatric surgery

Obesity has increased alarmingly in the United States and is increasing in many countries of the world. Because obesity is an important risk factor for type 2 diabetes and other chronic diseases, it is important to develop approaches to counter the rapid increase in adiposity. One approach is bariatric surgery, the most successful clinical intervention known for treating obesity. Surgery can result in impressive weight loss and improvement of obesity-related comorbidities. Yet the mechanisms responsible for this remarkable effect of surgery remain controversial. It is now clear that caloric restriction, per se, does not explain all the reduction in stored fat mass after surgery. A number of gastrointestinal hormones, including glucagon-like peptide (GLP)-1, peptide YY, oxyntomodulin, GLP-2, glucose-dependent insulinotropic polypeptide, ghrelin, and others, can play roles in energy homeostasis and could be involved in bariatric-surgery-related weight loss and weight loss maintenance. Vagal innervation may play a role. In addition, there may be other yet-uncharacterized factors that could participate. This review discusses the possible roles of these hormonal mechanisms in various types of bariatric surgery to help elucidate some of the potential mechanisms at play in short-term and long-term post-bariatric surgery weight loss. Understanding such mechanisms could lead to new and efficacious means to control or even reduce the epidemic of obesity.
