Adolescent Bariatric Surgery: Effects of Socioeconomic, Demographic, and Hospital Characteristics on Cost, Length of Stay, and Type of Procedure Performed

Assessment of electronic patient education materials for adolescent bariatric surgery candidates: An environment scan

Objective

Adolescents who opt for metabolic and bariatric surgery (MBS) will use the internet to learn about the procedure. The objective of this study is to assess the suitability of electronic patient education materials (ePEM) of North American centers that perform adolescent bariatric surgery.

Methods

Canadian and American bariatric centers that perform adolescent MBS were identified from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program and Google web-based searches. Suitability of ePEM for the adolescent readership was evaluated using the Suitability Assessment of Materials (SAM).

Results

Sixty-five centers were evaluated from June to July 2020 with 41% citing adolescent specific material. Six percent of the ePEM were evaluated as 'not suitable', 69% were evaluated as 'adequate', and 25% were evaluated as 'superior'.

Conclusion

Adequate ePEM scoring was obtained, but centers had little resources tailored to adolescent patients. Further research is needed to evaluate all the resources provided to adolescents (i.e., resources provided by the health team) to ensure the tools are appropriate for the adolescent readership.

Innovation

This environmental scan provided insights to ePEM available for adolescents considering MBS.

Long-term weight loss after bariatric procedures for morbidly obese adolescents and youth: a single-institution analysis with up to 19-year follow-up

BACKGROUND

Obesity is a public health concern among adolescents and young adults. Bariatric surgery is the most effective treatment for morbid obesity and has been increasingly utilized in young patients. Long-term outcomes data for bariatric surgery in this age group are limited.

METHODS

This is a single-institution, prospective analysis of 167 patients aged 15-24 years who underwent one of three laparoscopic bariatric procedures between 2001 and 2019: Roux-en-Y gastric bypass (LRYGB, n = 71), adjustable gastric banding (LAGB, n = 22), and sleeve gastrectomy (LSG, n = 74). Longitudinal weight and body mass index (BMI) measurements were compared to evaluate patterns of weight loss.

RESULTS

All operations were completed laparoscopically using the same clinical pathways. Patients were predominantly female (82.6%), had a median age of 22.0 [Q1-Q3 20.0-23.0] years, and had a mean presurgical BMI of 48.5 ± 6.5 kg/m² (range 38.4-68.1 kg/m²). All procedures produced significant weight loss by 1 year, peak weight loss by 2 years, and modest weight regain after 5 years. Mean percent weight/BMI losses at 5 years for LRYGB, LAGB, and LSG were - 36.7 ± 10.8%, - 14.5 ± 15.3%, and - 25.1 ± 13.4%, respectively (p < 0.001). LRYGB patients were most likely to achieve ≥ 25% weight loss at 1, 3, and 5 years and maintained significant average weight loss for more than 15 years after surgery. Reoperations were procedure-specific, with LAGB, LRYGB, and LSG having the highest, middle, and lowest reoperation rates, respectively (40.9% vs. 16.9% vs. 5.4%, p < 0.001).

CONCLUSION

All procedures provided significant and durable weight loss. LRYGB patients achieved the best and most sustained weight loss. LSG patients experienced second-best weight loss between 1 and 5 years, with lowest chance of reoperation. LAGB patients had the least weight loss and the highest reoperation rate. Compared to other factors, type of bariatric procedure was independently predictive of successful weight loss over time. More studies with long-term follow-up are needed.

National Trends and Outcomes in Adolescents Undergoing Bariatric Surgery

BACKGROUND

In the US, obesity continues to be a severe health issue now affecting adolescents. Bariatric surgery remains the most effective treatment for obesity, but use among adolescents remains low. The objective of this study was to identify current national trends in bariatric surgery among adolescents.

STUDY DESIGN

Using the Nationwide Inpatient Sample database, adolescents aged 9 to 19 with a diagnosis of morbid obesity who underwent a laparoscopic gastric bypass (Roux-en-Y gastric bypass) or laparoscopic sleeve gastrectomy (SG) between 2015 and 2018 were identified. Demographics, comorbidities, and in-hospital complications were collected. National estimates were calculated. The trend of annual number of operations was determined by Kruskal-Wallis rank test.

RESULTS

Between 2015 and 2018, 1,203 adolescents were identified, resulting in a nationwide estimate of 4,807 bariatric cases. The number of bariatric operations increased annually from 1,360 in 2015 to 1,740 operations in 2018 (p = 0.0771). The majority of patients were female (76%), 17 to 19 years old (84.1%), and White (47.9%). Most patients underwent SG (82.0%). Black and Hispanic patients comprised 40.2% of the cohort. Significant comorbidities included diabetes, dyslipidemia, nonalcoholic fatty liver disease, hypertension, and sleep apnea. The average length of stay decreased from 2.12 days to 1.64 days. There were no in-hospital mortalities, and complications were less than 1%.

CONCLUSIONS

With the increasing prevalence of obesity among adolescents in the US, bariatric surgery increased over time but was performed less in patients younger than 16 years of age and racial minorities. Bariatric surgery among adolescents remains safe, with extremely low complication rates and zero in-hospital mortality.

30-Day morbidity and mortality of bariatric metabolic surgery in adolescence during the COVID-19 pandemic - The GENEVA study

BACKGROUND

Metabolic and bariatric surgery (MBS) is an effective treatment for adolescents with severe obesity.

OBJECTIVES

This study examined the safety of MBS in adolescents during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

This was a global, multicentre and observational cohort study of MBS performed between May 01, 2020, and October 10,2020, in 68 centres from 24 countries. Data collection included in-hospital and 30-day COVID-19 and surgery-specific morbidity/mortality.

RESULTS

One hundred and seventy adolescent patients (mean age: 17.75 ± 1.30 years), mostly females (n = 122, 71.8%), underwent MBS during the study period. The mean pre-operative weight and body mass index were 122.16 ± 15.92 kg and 43.7 ± 7.11 kg/m² , respectively. Although majority of patients had pre-operative testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (n = 146; 85.9%), only 42.4% (n = 72) of the patients were asked to self-isolate pre-operatively. Two patients developed symptomatic SARS-CoV-2 infection post-operatively (1.2%). The overall complication rate was 5.3% (n = 9). There was no mortality in this cohort.

CONCLUSIONS

MBS in adolescents with obesity is safe during the COVID-19 pandemic when performed within the context of local precautionary procedures (such as pre-operative testing). The 30-day morbidity rates were similar to those reported pre-pandemic. These data will help facilitate the safe re-introduction of MBS services for this group of patients.

Wearable Activity Tracking Device Use in an Adolescent Weight Management Clinic: A Randomized Controlled Pilot Trial

BACKGROUND

The use of physical activity tracker devices has increased within the general population. However, there is limited medical literature studying the efficacy of such devices in adolescents with obesity. In this study, we explored the feasibility of using wearable activity tracking devices as an adjunct intervention on adolescents with obesity.

METHODS

Randomized controlled pilot trial evaluated the feasibility (attrition ≤50%) of an activity tracking intervention (ATI) and its effects on weight loss in adolescents with obesity enrolled in an adolescent weight management clinic (AWMC). Outcomes included feasibility (attrition rate) and absolute change in BMI. Differences between groups at 6, 12, and 18 weeks were examined.

RESULTS

Forty-eight participants were enrolled in the study. Eighteen subjects were randomly assigned to the ATI group and 30 to control. The average age was 14.5 years. Overall, the majority of participants were Hispanic (56%). Sexes were equally distributed. The average baseline BMI was 37.5 kg/m². At the study conclusion, the overall attrition rate was 52.1%, 44.4% in the ATI group versus 56.6% in the control group, with a differential attrition of 12.2%. The ATI and control groups each showed an absolute decrease in BMI of -0.25 and -2.77, respectively, with no significant differences between the groups.

CONCLUSION

The attrition rate in our study was >50%. Participation in the AWMC by the ATI and control groups resulted in maintenance of BMI and body weight for the study duration. However, the use of an activity tracking device was not associated with greater weight loss. This trial is registered with NCT03004378.

Current Perspectives on the Role of Very-Low-Energy Diets in the Treatment of Obesity and Type 2 Diabetes in Youth

In both developed and developing countries, pediatric obesity and type 2 diabetes are an increasing public health concern: globally 5.6% of girls and 7.8% of boys aged ≥5 years have obesity. The incidence of type 2 diabetes has increased in youth in recent decades and disproportionately affects those from ethnic/racial minority groups and disadvantaged backgrounds. For the treatment of both conditions, conventional lifestyle intervention is frequently ineffective, access to bariatric surgery is very limited and many young people are unsuitable or unwilling to undergo surgery. A very-low-energy diet (VLED) provides a viable alternative and may be effective for weight reduction and improved glycemic control in youth, based on one systematic review. In particular, in the treatment of type 2 diabetes, a chart review and a pilot study both demonstrated that a VLED can reduce the requirement for medications, including insulin, and lead to the remission of diabetes. However, long-term follow-up and safety data remain limited and therefore a VLED is inconsistently recommended by clinical practice guidelines for the treatment of pediatric obesity and type 2 diabetes. In clinical practice, VLED use in children and adolescents is uniquely challenging due to intolerance of expected side effects, difficulty adhering to the highly restrictive diet and difficulty with behaviour change within the current social context and environment. Ultimately, more research, including larger, longer-term trials with comprehensive safety monitoring are required to strengthen the evidence base. This would inform clinical practice guidelines, which may facilitate more widespread utilization of VLED programs in the management of obesity and type 2 diabetes in youth.

Use of sleeve gastrectomy in adolescents and young adults with severe obesity

PURPOSE OF REVIEW

The prevalence of pediatric obesity and its associated complications is increasing around the world. Treatment of obesity is challenging and metabolic and bariatric surgery (MBS) is currently the most effective treatment for this condition. At this time, vertical sleeve gastrectomy (VSG) is the most commonly performed bariatric procedure in adolescents. However, knowledge regarding the efficacy, safety, and durability of VSG in adolescents is still evolving. This review summarizes the most recent updates in the field of MBS particularly VSG in adolescents.

RECENT FINDINGS

MBS is recommended to treat moderate to severe obesity, especially when complicated by comorbidities. The use of VSG for weight loss is increasing among adolescents and produces similar weight loss at five years in both adolescents and adults. The physiologic mechanisms causing weight loss after VSG are multifactorial and still being investigated. The complication rate after VSG ranges between 0 and 17.5%.

SUMMARY

VSG appears to be a well-tolerated and effective procedure in adolescents. However, it continues to be underutilized despite the increasing prevalence of moderate to severe obesity in adolescents. It is thus important to educate providers regarding its benefits and safety profile.

One Size Does Not Fit All: Sociodemographic Factors Affecting Weight Loss in Adolescents

Successful lifestyle changes for weight reduction are heavily dependent on recognizing the importance of societal and cultural factors. Patients 13-19 years of age with a BMI ≥95^th percentile are eligible for our multidisciplinary adolescent weight loss clinic. A behavioral questionnaire was administered at the initial visit. Patients were seen every 4-6 weeks. Bivariate analysis was used to identify sociodemographic factors associated with differences in weight loss. Overall, receiving reduced cost meals was associated with a lower likelihood of losing weight (kg) (p < 0.01). When stratified by race, White adolescents were more likely to lose weight if caretakers reported having enough money to buy healthy food (p < 0.05); in contrast, Black adolescents were less likely to lose weight (p < 0.05). However, Black patients were more likely to lose weight if they reported eating fruits and vegetables (p < 0.05). Female adolescents were more likely to lose weight if they felt unhappy about their appearance (p < 0.05). Interestingly, male adolescents were less likely to lose weight if they felt unhappy about their appearance (p < 0.05). Social and cultural norms influence weight loss in adolescents in unique and differing ways. Culturally competent individualized interventions could increase weight loss in diverse groups of adolescents with obesity.

Short- and long-term safety and efficacy of bariatric surgery for severely obese adolescents: a narrative review

The selection criteria, safety, and efficacy of bariatric surgery are well established in adults but are less well defined for severely obese adolescents. The number of severely obese adolescents who could benefit from weight loss surgery is increasing, although referral rates have plateaued. Surgical options for these adolescents are controversial and raise several questions. Recent studies, including the prospective Teen-Longitudinal Assessment of Bariatric Surgery Study and the Adolescent Morbid Obesity Surgery Study, help answer these questions. Early bariatric surgical intervention improves body mass index but, more importantly, improves cardiovascular and metabolic co-morbidities of severe obesity. A review of the medical, psychosocial, and economic risks and benefits of bariatric surgery in severely obese adolescents is a step toward improving the management of a challenging and increasing population. We describe the current knowledge of eligibility criteria, preoperative evaluation, surgical options, outcomes, and referral barriers of adolescents for bariatric surgery.
