The association between patient attendance to a perioperative group-based lifestyle program and weight loss after bariatric surgery

Influence of mental and behavioral factors on weight loss after bariatric surgery: A systematic review and meta-analysis

INTRODUCTION

Multiple factors are related to lower weight loss after bariatric surgery. This review and meta-analysis evaluates the influence of several mental and behavioral factors on weight loss.

METHOD

Six electronic databases were searched. Percentage excess weight loss (%EWL) was calculated for all moderator and non-moderator groups of the variables: symptoms of depression, anxiety and binge eating, compliance, physical activity, quality of life, and body image. All moderators, surgery types, and follow-up moments were analyzed separately.

RESULTS

In total, 75 articles were included in the review; 12 meta-analyses were conducted. Higher postoperative compliance to follow-up was associated with 6.86%-13.68% higher EWL. Preoperative binge eating was related to more weight loss at 24- and 36-month follow-up (7.97% and 11.79%EWL, respectively). Patients with postoperative binge eating symptoms had an 11.92% lower EWL. Patients with preoperative depressive symptoms lost equal weight compared to patients without symptoms.

CONCLUSION

Despite the high heterogeneity between studies, a trend emerges suggesting that the presence of postoperative binge eating symptoms and lower postoperative compliance may be associated with less weight loss after bariatric-metabolic surgery. Additionally, preoperative depressive symptoms and binge eating do not seem to significantly impact weight loss.

[Weight Loss Experience of Highly Obese Young Adult Who Underwent Bariatric Surgery]

PURPOSE

This study aimed to explore the weight loss experience of highly obese young people who underwent bariatric surgery.

METHODS

Data were collected, from October 2021 to April 2022, through individual in-depth interviews with eight highly obese young adults who underwent bariatric surgery and analyzed using Colaizzi's phenomenological method.

RESULTS

The following four theme clusters were extracted. First, 'The unbearable sorrow of obese people' explains the process of choosing bariatric surgery after fluctuations and frustration despite countless repeated weight loss attempts. Second, 'The impact aftermath of bariatric surgery' revealed participants struggling in the face of unexpected changes due to bariatric surgery. Third, 'Efforts to rebuild a healthy myself' demonstrated the struggle to regain health by using the surrounding support system to overcome the difficulties of this surgical procedure. Lastly, 'Facing life by getting rid of the yoke of obesity' displayed the experiences of the participants who felt ambivalent about their changed appearance, but coping positively with the new life.

CONCLUSION

This study provides an in-depth understanding of the weight loss experiences of highly obese adolescents who underwent bariatric surgery and presents a new perspective on clinical practice. The results of this study are expected to be useful in developing and applying systematic and customized nursing interventions before and after bariatric surgery.

A Decision Aid to Help Patients Make Informed Choices Between the Laparoscopic Gastric Bypass or Sleeve Gastrectomy

PURPOSE

In the Netherlands, patients can often choose between the laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) as primary bariatric surgery. Yet, patients confronted with medical options may experience decisional conflict when their stakes are high and outcomes uncertain. This study aimed to assess if a decision aid helps patients make informed choices between two bariatric procedures by lowering the level of decisional conflict.

MATERIALS AND METHODS

This study was a single-center comparative cohort of patients who accessed a web-based decision aid (intervention group) and those who did not use the decision aid (control group) to help choose between two bariatric procedures additional to the standard provided care. The primary outcome was the level of decisional conflict in these patients using the decisional conflict scale (DCS). Secondary outcomes were patient satisfaction with the provided information (BODY-QTM-satisfaction with information), preference of involvement in procedure selection, level of shared decision-making (SDM-Q-9 questionnaire), and patient knowledge.

RESULTS

The level of decisional conflict assessed with the decisional conflict scale (DCS) showed a significantly lower mean total DCS of 25.5 ± 11.5 for the intervention group vs. 29.1 ± 12.4 in the control group (p = 0.022). Both groups did not significantly differ in satisfaction regarding provided information, involvement in the selection procedure, shared decision-making, and patient knowledge.

CONCLUSION

The results suggest that the additional use of a decision aid significantly lowers the level of decisional conflict in patients awaiting bariatric surgery. However, the added value should be further investigated.

Characterization of Pre- and Postpandemic 30-Day Follow-Up After Elective Bariatric Surgery: a Retrospective MBSAQIP Analysis of 834,646 Patients

BACKGROUND

Effects of the COVID-19 pandemic on rates of early postoperative follow-up after bariatric surgery are poorly understood. Our study characterizes 30-day follow-up after bariatric surgery prior to COVID-19 (years 2015-2019) and during the pandemic of COVID-19 (year 2020) and evaluates general predictive factors of short-term follow-up.

METHODS

Data was extracted from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data registry from 2015 to 2020. Cohorts were divided into pre-pandemic and pandemic years and patients with and without 30-day follow-up. Multivariable logistic regression analysis was used to identify general factors independently predictive of 30-day follow-up. The primary aim was to evaluate the impact of the COVID-19 pandemic on short-term 30-day follow-up adherence. A secondary outcome was to characterize general short-term postoperative 30-day follow-up associated with elective bariatric surgery and identify independent predictors of 30-day follow-up among bariatric surgery patients using multivariable logistic regression analysis.

RESULTS

A total of 834,646 patients were identified. Follow-up rates significantly increased in the COVID era in 2020 (p < 0.0001). Patients who achieved 30-day follow-up were older and had an increased burden of medical comorbidities, including non-insulin and insulin-dependent diabetes mellitus, hypertension, dyslipidemia, as well as increased BMI compared to patients lacking follow-up. The cohort with successful 30-day follow-up was more likely to receive gastric bypass and had increased rates of metabolic comorbidities. After adjusting for comorbidities, the greatest independent predictors of follow-up were the 2020 COVID-19 era year, Asian race, black race, and gastroesophageal reflux disease.

CONCLUSIONS

After adjusting for comorbidities, the 2020 COVID-19 era year was one of the greatest predictors of follow-up after bariatric surgery. Postoperative follow-up rates after elective bariatric surgery are excellent at > 95% and increased during the 2020 COVID-19 era year. Several independent predictors of follow-up were identified which may help in development of strategies aimed to mitigate lack of postoperative follow-up.

The Long-Term Impact of Postoperative Educational Programs on Weight Loss After Roux-en-Y Gastric Bypass

Purpose

Roux-en-Y gastric bypass (RYGB) is a well-documented treatment of severe obesity. Attending postoperative educational programs may improve the outcome. The aim of this study was to evaluate whether participation in educational programs lasting 2–3 years after RYGB influences long-term weight loss, weight regain, physical activity, and compliance to multivitamin supplements.

Materials and Methods

The Bariatric Surgery Observation Study (BAROBS) is a multicenter retrospective, cross-sectional study 10–15 years after primary RYGB. Four hundred and ninety-seven participants answered questions regarding participation in postoperative educational programs. Participants were divided into frequent attendees (FA) and infrequent attendees (IFA) at the educational programs.

Results

Ten to 15 years after surgery, a total weight loss (TWL) of 23.2 ± 11.6% were seen in the FA group vs 19.5 ± 12.6% in the IFA group, p < 0.001. Percent excess weight loss (%EWL) was 55.7 ± 28.9% vs 46.0 ± 31.1%, p < 0.001. Weight regain in percent of maximal weight loss for the FA was 32.1 ± 32.8% vs IFA 38.4 ± 40.0%, p = 0.052. No difference between the groups in compliance to multivitamin and physical activity.

Conclusion

Participants with frequent participation in group-based educational programs had better weight loss outcomes 10–15 years after RYGB and tended to have less weight regain. There was no difference between the two groups in participants compliance to recommended multivitamin supplements and physical activity.
