Participation and Compliance in a Multimodal Prehabilitation Program for Colorectal Cancer (PACE): A Qualitative Study.

Purpose: Interest in prehabilitation, the preoperative enhancement of patients' condition, is rising in the surgical field. Challenging factors appear to be patients' motivation to participate in and their compliance with prehabilitation programs. The aim of this qualitative study was to study the real-life experience of prehabilitation by assessing the lived experience and perceptions of participants in a multimodal prehabilitation program and to explore factors that influence participation and compliance during prehabilitation.

Short-term safety and effectiveness of conversion from sleeve gastrectomy to Ring augmented Roux-en-Y gastric bypass.

Background: Weight recurrence, suboptimal clinical response and functional disorder (such as reflux) after a Sleeve Gastrectomy (SG) are problems that may require conversional surgery. For reflux, conversion to Roux-en-Y Gastric Bypass (RYGB) is considered effective. Regarding treatment for suboptimal clinical response, the technique of choice remains a subject of debate.

The POSE-2 Procedure for People with Obesity: A Safe and Effective Treatment Option.

Purpose: Besides lifestyle interventions, medication, and surgery, endoscopic options are becoming part of the current treatment landscape for people with obesity. With the POSE (Primary Obesity Surgery Endoscopic) procedure, endoluminal folds are created in the stomach with full-thickness sutures. Recently, the modified version, POSE-2, was introduced in clinical practice.

Cost-effectiveness and safety of continuous pulse oximetry for management of undiagnosed obstructive sleep apnea in bariatric surgery: a nationwide cohort study.

Background: Undetected obstructive sleep apnea (OSA) is highly prevalent in patients undergoing bariatric surgery and increases perioperative risks. Screening for OSA using preoperative polygraphy (PG) with subsequent continuous positive airway pressure (CPAP) is costly and time-consuming. Postoperative continuous pulse oximetry (CPOX) is less invasive, and is hypothesized to be a safe and cost-effective alternative.

Optimizing Hospital Performance Evaluation in Total Weight Loss Outcomes After Bariatric Surgery: A Retrospective Analysis to Guide Further Improvement in Dutch Hospitals.

Introduction: Bariatric surgery aims for optimal patient outcomes, often evaluated through the percentage total weight loss (%TWL). Quality registries employ funnel plots for outcome comparisons between hospitals. However, funnel plots are traditionally used for dichotomous outcomes, requiring %TWL to be dichotomized, potentially limiting feedback quality.

The Impact of Longer Biliopancreatic Limb Length on Weight Loss and Comorbidity Improvement at 5 Years After Primary Roux-en-Y Gastric Bypass Surgery: A Population-Based Matched Cohort Study.

Introduction: Different limb lengths are used in Roux-en-Y gastric bypass (RYGB) surgery, as there is no consensus which limb length strategy has the best outcomes. The biliopancreatic limb (BPL) is thought to play an important role in achieving weight loss and associated comorbidity resolution. The objective of this study was to assess the impact of a longer BPL on weight loss and comorbidity improvement at 5 years after primary RYGB.

Convincing 10-Year Follow-up Results of the Banded Roux-en-Y Gastric Bypass.

Introduction: Several studies have shown the positive effect on weight loss of the banded Roux-en-Y gastric bypass (BRYGB). Thus far, studies describing the 10-year post-operative results are scarce. Therefore, the aim of this study was to describe the weight loss results, effect on associated medical problems, and complication rates during 10 years of follow-up after BRYGB.

Weight Loss and Glycemic Control After Bariatric Surgery in Adolescents With Severe Obesity: A Randomized Controlled Trial.

Purpose: Bariatric surgery is regarded as a valuable treatment option for adolescents with severe obesity. However, high-quality evidence of its superiority over prolonged conservative treatment with multidisciplinary lifestyle intervention (MLI) is limited. This study investigated the efficacy and safety of bariatric surgery in adolescents without sufficient weight loss after MLI for severe obesity.

Laparoscopic Conversion of Vertical Banded Gastroplasty to Roux-en-Y Gastric Bypass Gives Better Result Compared to an Open Approach.

Background: Vertical banded gastroplasty (VBG) has a relatively high failure rate in the long run, requiring revisional surgery in 30-65%. A common conversion option is to Roux-en-Y gastric bypass (RYGB), which can be performed laparoscopically or open. Current literature contains small cohorts and inconclusive results.

The Swallowable Intragastric Balloon Combined with Lifestyle Coaching: Short-Term Results of a Safe and Effective Weight Loss Treatment for People Living with Overweight and Obesity.

Background: Some patients with overweight or obesity are not eligible for surgery according to international guidelines or do not wish a surgical intervention. For these patients, different treatment options are being explored. In this study, we examined the effectiveness of the swallowable intragastric balloon (IB) combined with lifestyle coaching, in patients living with overweight and obesity.

Weight recurrence after Sleeve Gastrectomy versus Roux-en-Y gastric bypass: a propensity score matched nationwide analysis.

Background: Literature remains scarce on patients experiencing weight recurrence after initial adequate weight loss following primary bariatric surgery. Therefore, this study compared the extent of weight recurrence between patients who received a Sleeve Gastrectomy (SG) versus Roux-en-Y gastric bypass (RYGB) after adequate weight loss at 1-year follow-up.

Methods: All patients undergoing primary RYGB or SG between 2015 and 2018 were selected from the Dutch Audit for Treatment of Obesity.

Safety of bariatric surgery in the elderly: results from the Dutch National Registry.

Background: The increased human life expectancy and prevalence of obesity lead to more elderly people with obesity. As the popularity of bariatric surgery continues to grow, more elderly persons apply for bariatric surgery. However, because of the potentially higher surgical risk in elderly patients, bariatric surgery has been performed in small numbers.

Predicting serious complication risks after bariatric surgery: external validation of the Michigan Bariatric Surgery Collaborative risk prediction model using the Dutch Audit for Treatment of Obesity.

Background: Risk-prediction tools can support doctor-patient (shared) decision making in clinical practice by providing information on complication risks for different types of bariatric surgery. However, external validation is imperative to ensure the generalizability of predictions in a new patient population.

Objective: To perform an external validation of the risk-prediction model for serious complications from the Michigan Bariatric Surgery Collaborative (MBSC) for Dutch bariatric patients using the nationwide Dutch Audit for Treatment of Obesity (DATO).

Hospital Variation in Preference for a Specific Bariatric Procedure and the Association with Weight Loss Performance: a Nationwide Analysis.

Purpose: Hospitals performing a certain bariatric procedure in high volumes may have better outcomes. However, they could also have worse outcomes for some patients who are better off receiving another procedure. This study evaluates the effect of hospital preference for a specific type of bariatric procedure on their overall weight loss results.

Higher Preoperative Weight loss Is Associated with Greater Weight Loss up to 12 Months After Bariatric Surgery.

Background: Prior research suggested presurgical weight loss is associated with greater total weight loss, resulting in a more effective bariatric intervention. We aimed to assess whether preoperative weight loss is a predictor for total weight loss, and which patient factors are associated with successful weight loss.

Methods: All patients (N = 773) that underwent primary bariatric surgery between June 2017 and August 2019 were included in this single-center retrospective study.

Conversion to Roux-en-Y gastric bypass versus one-anastomosis gastric bypass after a failed primary gastric band: a matched nationwide study.

Background: Primary laparoscopic adjustable gastric band (LAGB) has high rates of patients not achieving the desired weight loss, and it remains unclear which bariatric conversion procedure gives better results.

Objective: To compare weight loss among patients undergoing conversion one-anastomosis gastric bypass (cOAGB) and conversion Roux-en-Y gastric bypass (cRYGB) after a failed LAGB.

Setting: Nationwide population-based study including all 18 hospitals providing metabolic and bariatric surgery.

The Benefits of Banded over Non-banded Roux-en-Y Gastric Bypass in Patients with Morbid Obesity: a Multi-center Study.

Background: Roux-en-Y gastric bypass (RYGB) has proven to be an effective treatment for obesity with excellent long-term results, even though weight regain can occur. A method to improve the results of RYGB and minimize chance of weight regain is banded RYGB. Better sustained weight loss is also related to higher remission of comorbidities.

Esophageal Cancer After Bariatric Surgery: Increasing Prevalence and Treatment Strategies.

Purpose: The number of bariatric procedures has increased exponentially over the last 20 years. On the background of ever-increasing incidence of esophageal malignancies, the altered anatomy after bariatric surgery poses challenges in treatment of these cancers. In this study, an epidemiological estimate is presented for the future magnitude of this problem and treatment options are described in a retrospective multicenter cohort.

Current preoperative strategies applied in the Dutch bariatric centers: A national survey.

There is no consensus about the optimal management of patients undergoing bariatric surgery. This study aimed to identify current weight loss goals prior to bariatric surgery, as well as aimed to explore preoperative strategies related to diet, nutritional supplements and physical activity. An online survey was distributed among bariatric surgeons and dietitians in all 18 Dutch bariatric centers.

Comparison of Linear versus Circular-Stapled Gastroenterostomy in Roux-en-Y Gastric Bypass: A Nationwide Population-Based Cohort Study.

Background: When performing a Roux-en-Y gastric bypass (RYGB), the gastroenterostomy can be constructed with a circular stapled or linear stapled technique. The size of the gastroenterostomy depends on the stapling method and this may affect weight loss outcomes. The aim of this study was to examine the impact of the stapling technique on weight loss outcomes after RYGB.

National Bariatric Surgery Registries: an International Comparison.

Introduction: Pooling population-based data from all national bariatric registries may provide international real-world evidence for outcomes that will help establish a universal standard of care, provided that the same variables and definitions are used. Therefore, this study aims to assess the concordance of variables across national registries to identify which outcomes can be used for international collaborations.

Methods: All 18 countries with a national bariatric registry who contributed to The International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) Global Registry report 2019 were requested to share their data dictionary by email.

Metabolic effects of bariatric surgery on patients with type 2 diabetes: a population-based study.

Background: Bariatric surgery among patients with obesity and type 2 diabetes (T2D) can induce complete remission. However, it remains unclear whether sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) has better T2D remission within a population-based daily practice.

Objectives: To compare patients undergoing RYGB and SG on the extent of T2D remission at the 1-year follow-up.
