Long-term outcomes of bariatric surgery in adolescents with severe obesity (FABS-5+): a prospective follow-up analysis

Asthma incidence and severity are increased in obese populations. Systematic reviews have shown benefit from weight-loss interventions on asthma outcomes, but the role of bariatric surgery is still unclear. In this review, cohorts of obese asthmatic patients undergoing bariatric surgery were examined regarding different asthma outcomes. The available data on patients who were followed up showed improvements in asthma control, exacerbation risk, asthma-related hospitalisation, medication use and airway hyperresponsiveness, with some patients not requiring further treatment for asthma. Follow-up duration was variable, being mostly of 1 year, with some studies reporting long-term outcomes after 5 years. The studies reviewed had many limitations, including small numbers of patients, lack of control arm in some studies and lack of standardisation of asthma diagnosis, classification and outcome measures, in addition to possible reporting bias. Data on small numbers of patients also show the possibility of benefit exclusively in nonallergic asthma. Larger, more stringent clinical trials are needed before recommending bariatric surgery for treatment of asthma.

Weight Outcomes

Background: Obesity is considered a global chronic disease requiring weight management through lifestyle modification, pharmacotherapy, or weight loss surgery. The dramatic increase in patients with severe obesity in Saudi Arabia is paralleled with those undergoing bariatric surgery. Although known to be beneficial in the short term, the long-term impacts of surgery within this group and the sustainability of weight loss after surgery remains unclear. Objectives: We aimed to assess the long-term weight outcomes after bariatric surgery. Setting: The study was conducted at King Khalid University Hospital (KKUH), King Saud University Medical City (KSUMC) in Riyadh, Saudi Arabia. Methods: An observational prospective cohort study on adult patients with severe obesity undergoing bariatric surgery (sleeve gastrectomy (SG) or Roux-en Y gastric bypass (RYGB)) during the period between 2009 and 2015 was conducted. Weight loss patterns were evaluated pre- and post-surgery through clinical and anthropometric assessments. Absolute weight loss was determined, and outcome variables: percent excess weight loss (%EWL), percent total weight loss (%TWL), and percent weight regain (%WR), were calculated. Statistical analysis using univariate and multivariate general linear modelling was carried out. Results: A total of 91 (46 males and 45 females) patients were included in the study, with the majority belonging to the SG group. Significant weight reductions were observed at 1 and 3 years of follow-up (p < 0.001) from baseline. The %EWL and %TWL were at their maximum at 3 years (72.4% and 75.8%) and were comparable between the SG and RYGB. Decrements in %EWL and %TWL and increases in %WR were seen from 3 years onwards from bariatric surgery until the study period ended. The yearly follow-up attrition rate was 20.8% at 1 year post-surgery, 26.4% at year 2, 31.8% at year 3, 47.3% at year 4, 62.6% at year 5, and 79.1% at end of study period (at year 6). Conclusion: The major challenge to the successful outcome of bariatric surgery is in maintaining weight loss in the long-term and minimizing weight regain. Factors such as the type of surgery and gender need to be considered before and after surgery, with an emphasis on the need for long-term follow-up to enssure the optimal benefits from this intervention.

Adolescent Bariatric Surgery

Adolescent obesity has markedly increased worldwide in both its extent and prevalence in recent decades and obesity prevention strategies are failing. As a result, effective treatment strategies are urgently needed. As behavioral and pharmacological treatment approaches have only moderate effects in severe obesity, bariatric surgery has begun to emerge as a treatment option. In this debate article, we offer arguments opposing and supporting bariatric surgery in the treatment of severe obesity in adolescents. Bariatric surgery has superior therapeutic outcomes with respect to weight loss and resolution of comorbid diseases over other existing treatments. However, long-term outcomes after bariatric surgery in adolescents are only just beginning to emerge. Furthermore, the procedures are generally considered irreversible, apart from gastric banding. Most importantly, not all adolescents seem to benefit greatly from bariatric surgery and we are not yet able to reliably identify those who stand to gain the greatest benefit. The authors agree that adolescent bariatric surgery should be offered exclusively within formal adolescent obesity programs, delivered by specialist multidisciplinary child/adolescent obesity teams, and within specialist centers, in order to optimize outcomes and minimize potential detrimental effects. Patients and their family/carers must be educated regarding the benefits and risks, potential side effects, expected changes in eating behavior and the lifelong requirement for regular medical follow-up after surgery. Before embarking upon a surgical treatment pathway in adolescents with severe obesity, it may also be beneficial to ensure compliance to treatment is demonstrated, in order to minimize the risk of nutritional deficiencies and associated potential complications.

Long Term Outcome

Background: Severe obesity among adolescent shows a worrisome trend in regard of its increasing prevalence and poses a great challenge for treatment. Conservative measures have modest effects on weight loss, usually fail in achieving a sustainable weight loss and resolution of comorbidities. This has led to greater utilization of bariatric surgery (BS) that offers a fast reduction in body mass index (BMI) with little perioperative complications. Despite the increasing utilization of BS, data is still insufficient, regarding their long-term outcome in adolescents. We review short and long-term effects of bariatric surgery and their implications on bone health and nutritional deficiencies in adolescents. In addition, we discuss possible pharmaceutical alternatives. Summary: BS results in a substantial weight loss of roughly 37% in the first-year post-operation and is superior to conservative measures in resolution of metabolic comorbidities. BS significantly improves health-related quality of life. Longer follow up, shows weight regain in 50% of patients. Furthermore, reduced bone mass and nutritional deficiencies were reported in up to 90% of patients. Most recently, alternative to BS became more relevant with approval of GLP-1 analogues use in adolescents. GLP-1 analogues are potent enough to induce moderate clinically meaningful weight loss and improvement of metabolic component. Key Messages: We conclude that obese adolescents without major obesity related complications may benefit from pharmacological interventions with lifestyle modification. We advise considering BS as treatment approach in adolescents with severe obesity and major obesity related complications with proper pre-operative preparation and post operative follow up in excellence centers.

Abstract Background Obesity is commonly observed in patients with cirrhosis, especially with the increasing prevalence of non-alcoholic steatohepatitis (NASH). Bariatric surgery has been avoided in these patients given concerns about increased perioperative risk; therefore, data are lacking regarding long-term outcomes. In this study, we aimed to evaluate the long-term outcomes of patients with cirrhosis who underwent bariatric surgery. Methods We reviewed the charts of adult patients with compensated cirrhosis who underwent bariatric surgery after they were prospectively enrolled between February 23, 2009 and November 9, 2011, and followed in a pilot study for evaluation of bariatric surgery outcomes. Only patients with more than 4 years of follow-up were included in the analysis. Data regarding their liver disease, metabolic status, and survival were collected. A descriptive analysis was performed. Results The cohort consisted of 10 patients, of whom 7 were females. The median post-surgical follow-up was 8.7 years (± 1.4 years). All patients had biopsy-proven NASH; two patients had concurrent, untreated hepatitis C infection. During the observation period, there was a mean weight loss of 24 kg (19.2% of total body weight pre surgery, P < 0.001) and only one patient regained weight to the baseline pre-surgical measurement. One patient who was not eligible for transplant developed hepatic encephalopathy 3 years after surgery and later died. The remainder of the patients did not have any hepatic decompensation, cardiovascular event, or mortality. Except for one patient with Gilbert syndrome, bilirubin was normal in all patients at last follow-up. Conclusions Bariatric surgery in patients with compensated cirrhosis can lead to sustained weight loss and stable hepatic function on long-term follow-up.
