Background
Metabolic and bariatric surgery is a safe and effective treatment strategy for severe childhood obesity, affecting 10% of US adolescents.
Objectives
This prospective observational study addresses knowledge gaps related to changes in weight, cardiometabolic risk, and weight-related quality of life (WRQOL) in adolescents 10 years after laparoscopic adjustable gastric band (LAGB) insertion.
Setting
Five Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) US centers.
Methods
Anthropometric, micronutrient, cardiometabolic risk, and WRQOL data were collected on 274 adolescents undergoing metabolic and bariatric surgery, of which 14 participants underwent LAGB insertion (2008–2011). Descriptive analyses compared outcomes from baseline to 10 years.
Results
Participants were mostly female (86%), White (71%), with a median age of 18.5 years and preoperative median BMI of 49. Baseline prevalence of type 2 diabetes, hypertension, and dyslipidemia were 1 of 14 (7%), 8 of 14 (57%), and 8 of 13 (62%), respectively, versus 10-year prevalence of 1 of 8 (13%), 4 of 10 (40%), and 3 of 9 (33%), respectively. Two participants underwent LAGB removal (years 2 and 3), whereas two converted from LAGB to Roux-en-Y gastric bypass (years 2 and 6). Following initial BMI reduction (−10%) at year 1, 10-year median BMI in the LAGB retention group was 51, representing a 9.2% increase versus baseline. Micronutrient abnormalities and WRQOL remained similar between baseline and 10 years. One participant (1 of 14) withdrew from the study at year 7.
Conclusions
Long-term follow-up of this cohort reveals that LAGB had minimal impact on BMI, cardiometabolic risk factors, and WRQOL among adolescents. These results confirm the limited efficacy of LAGB in the pediatric population.

Background
Follow-up care after bariatric surgery is essential in preventing postsurgical complications and promoting long-term weight loss maintenance. However, many patients do not attend postsurgical appointments with the bariatric team, which may contribute to poor surgical outcomes.
Objectives
This study sought to understand sociodemographic factors related to follow-up appointment attendance and weight outcomes. The first objective was to determine whether there was a relationship between 1-year follow-up appointment attendance and sociodemographic factors. The second objective was to determine whether patients from certain sociodemographic groups were more likely to attend a 2-year follow-up appointment. The third objective was to determine whether there were differences in weight outcomes for patients who attended follow-up appointments compared with those who did not attend.
Setting
University hospital, United States.
Methods
This study was a retrospective observational study. Participants included 841 adult patients who underwent bariatric surgery, of whom 505 (60.05%) attended a 1-year appointment with the bariatric team (348 attended a follow-up visit with another medical provider), and 398 (47.32%) who had any follow-up medical visit at 2 years after surgery. Sociodemographic variables were collected during a presurgical psychological evaluation. Weight-related variables were obtained through patients’ electronic medical records 12 and 24 months after surgery.
Results
Younger patients and those with lower education levels were less likely to attend the 1-year follow-up appointment with the bariatric team. People who attend 1-year follow-up with bariatric team have more favorable weight outcomes at 1 year and 2 years after surgery.
Conclusions
Follow-up appointment attendance with the bariatric team may be a critical factor in the effectiveness of bariatric surgery. Bariatric surgery teams should employ strategies to increase attendance at the 1-year follow-up visit with the surgical team. Additional strategies should be enacted to increase follow-up appointment attendance for patients with lower education levels.

Background
On the basis of our extensive experience in same-day discharge (SDD) sleeve gastrectomy, we extended this management strategy to anastomotic metabolic and bariatric surgeries (MBS).
Objectives
To retrospectively analyze early outcomes (≤30 d) after anastomotic MBS with planned SDD (≤12 hr).
Setting
University Hospital, Canada; Public Practice.
Methods
SDD anastomotic MBS were proposed with strict preoperative criteria and included single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S), Roux-en-Y gastric bypass (RYGB), one-anastomosis gastric bypass (OAGB), and single-anastomosis sleeve ileal bypass (SASI). Enhanced recovery after bariatric surgery protocols and post-anesthesia care unit criteria were followed. Unplanned overnight stay, emergency department (ED) visit, readmission, morbidity-mortality, and reintervention rates were analyzed.
Results
Since 2021, 208 patients (191 female and 17 male) have undergone SDD anastomotic MBS, with 76% conversion procedures: 92 SADI-S, 72 RYGB, 35 OAGB, and 9 SASI (mean age = 41.4 yr and mean preoperative body mass index = 41.9 kg/m2). Unplanned overnight stays and ED visits were 4.8% and 4.3%, respectively. Readmission rate was 5.8% (5 SADI-S, 5 RYGB, 1 OAGB, and 1 SASI). Overall morbidity rate was 14.9%, including 3.9% major complications. Within 30 days postoperatively, there were 2 duodenal leaks, 1 intrabdominal collection, 1 common bile duct stenosis, and 1 acute appendicitis in the SADI-S group. There were 2 occlusions on the jejunojejunal anastomosis and 1 bleeding on the gastrojejunal anastomosis in the RYGB group. Five (2.4%) required reintervention with no mortality.
Conclusions
We report low and acceptable rates of unplanned overnight stay, readmission, and reintervention. Early outcomes suggest that SDD anastomotic MBS seems safe and feasible with an experienced team, selective criteria, and appropriate postoperative follow-up.

Background
The pilot study addresses the challenge of predicting postoperative outcomes, particularly body mass index (BMI) trajectories, following bariatric surgery. The complexity of this task makes preoperative personalized obesity treatment challenging.
Objectives
To develop and validate sophisticated machine learning (ML) algorithms capable of accurately forecasting BMI reductions up to 5 years following bariatric surgery aiming to enhance planning and postoperative care. The secondary goal involves the creation of an accessible web-based calculator for healthcare professionals. This is the first article that compares these methods in BMI prediction.
Setting
The study was carried out from January 2012 to December 2021 at GZOAdipositas Surgery Center, Switzerland. Preoperatively, data for 1004 patients were available. Six months postoperatively, data for 1098 patients were available. For the time points 12 months, 18 months, 2 years, 3 years, 4 years, and 5 years the following number of follow-ups were available: 971, 898, 829, 693, 589, and 453.
Methods
We conducted a comprehensive retrospective review of adult patients who underwent bariatric surgery (Roux-en-Y gastric bypass or sleeve gastrectomy), focusing on individuals with preoperative and postoperative data. Patients with certain preoperative conditions and those lacking complete data sets were excluded. Additional exclusion criteria were patients with incomplete data or follow-up, pregnancy during the follow-up period, or preoperative BMI ≤30 kg/m2.
Results
This study analyzed 1104 patients, with 883 used for model training and 221 for final evaluation, the study achieved reliable predictive capabilities, as measured by root mean square error (RMSE). The RMSE values for three tasks were 2.17 (predicting next BMI value), 1.71 (predicting BMI at any future time point), and 3.49 (predicting the 5-year postoperative BMI curve). These results were showcased through a web application, enhancing clinical accessibility and decision-making.
Conclusion
This study highlights the potential of ML to significantly improve bariatric surgical outcomes and overall healthcare efficiency through precise BMI predictions and personalized intervention strategies.
