Abstract
In 2007, the Scandinavian Obesity Surgery Registry (SOReg) was started by the profession to monitor the results of bariatric surgery and to provide a high-quality database for research. In the end of August 2023, SOReg contains 88,379 patients (body mass index [BMI] 41.7 kg/m2 , 41.2 years, 77.1% females, gastric bypass 76.8%). In this narrative review, we demonstrate that preoperative weight loss is of value and that the laparoscopic double omega-loop technique is highly suitable for gastric bypass. Closing the mesenteric openings is, however, important. Swedish bariatric surgery has low mortality, and our results are comparative to those of other countries. Significant long-term improvements are found in common obesity-related diseases such as diabetes, hypertension, and sleep apnea. Furthermore, the risk for cardiac failure and major adverse cardiovascular events is significantly reduced. Pregnancy-related outcomes are also improved. Gastric bypass results in significant improvements in quality of life and seems to be cost saving. We have revealed that low socioeconomic status is associated with reduced chance of undergoing bariatric surgery and inferior outcomes. Of note, we have performed several randomized clinical trials within the registry database. In conclusion, high-quality national registry databases, such as SOReg, are important for maintaining high-quality care and present a platform for extensive research.

Cost-effectiveness of metabolic surgery for the treatment of type 2 diabetes and obesity: a systematic review of economic evaluations. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2023; 24:575-590. [PMID: 35869383 PMCID: PMC10175448 DOI: 10.1007/s10198-022-01494-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Accepted: 06/21/2022] [Indexed: 05/12/2023]
Abstract
AIM To systematically identify and appraise the international literature on the cost-effectiveness of metabolic surgery for the treatment of comorbid type 2 diabetes (T2D) and obesity. METHODS A systematic search was conducted in electronic databases and grey literature sources up to 20 January 2021. Economic evaluations in a T2D population or a subpopulation with T2D were eligible for inclusion. Screening, data extraction, critical appraisal of methodological quality (Consensus Health Economic Criteria list) and assessment of transferability (International Society for Pharmacoeconomics and Outcomes Research questionnaire) were undertaken in duplicate. The incremental cost-effectiveness ratio (ICER) was the main outcome. Costs were reported in 2020 Irish Euro. Cost-effectiveness was interpreted using willingness-to-pay (WTP) thresholds of €20,000 and €45,000/quality-adjusted life year (QALY). Due to heterogeneity arising from various sources, a narrative synthesis was undertaken. RESULTS Thirty studies across seventeen jurisdictions met the inclusion criteria; 16 specifically in a T2D population and 14 in a subpopulation with T2D. Overall, metabolic surgery was found to be cost-effective or cost-saving. Where undertaken, the results were robust to sensitivity and scenario analyses. Of the 30 studies included, 15 were considered high quality. Identified limitations included limited long-term follow-up data and uncertainty regarding the utility associated with T2D remission. CONCLUSION Published high-quality studies suggest metabolic surgery is a cost-effective or cost-saving intervention. As the prevalence of obesity and obesity-related diseases increases worldwide, significant investment and careful consideration of the resource requirements needed for metabolic surgery programmes will be necessary to ensure that service provision is adequate to meet demand.

Abstract
PURPOSE Obesity is a growing global issue with evidence linking it to an increase in loss of disease-free years, reduced quality of life, increased mortality, and additional economic burden. This study sought to establish the cost-effectiveness of gastric bypass and sleeve gastrectomy, compared to conventional therapy in patients with obesity, from a Tunisian healthcare payor perspective. PATIENTS AND METHODS A Markov model compared lifetime costs and outcomes of bariatric surgery with conventional treatment among patients with body mass index (BMI) ≥ 40 kg/m2, BMI ≥ 35 kg/m2 with obesity-related co-morbidities (Group 1), or BMI ≥ 35 kg/m2 with type 2 diabetes mellitus (T2DM) (Group 2). Inputs were sourced from the Tunisian Health Examination Survey, local clinician data and literature sources. Health states were associated with different cost and utility decrements. Changes in body mass index, systolic blood pressure, lipid ratio and diabetes remission rates were modelled on a yearly basis. The incremental cost-effectiveness ratio (ICER), quality-adjusted life years (QALYs) and net monetary benefit (NMB) were key outcomes. Sensitivity and scenario analyses were performed to test the model's robustness. RESULTS The model showed that the benefits of bariatric surgery were favorable compared to conventional treatment, with an ICER of 1844 TND/QALY in Group 1 patients and 2413 TND/QALY in Group 2 patients. Bariatric surgery resulted in a QALY gain of 3.26 per patient in Group 1 and a gain of 1.77 per patient in Group 2. At a willingness to pay threshold of 31,379 TND/QALY, the incremental NMB was 96,251 TND and 51,123 TND for Group 1 and Group 2, respectively. CONCLUSION From the Tunisian healthcare payor perspective, bariatric surgery is cost-effective for patients with obesity and those with T2DM and obesity-related comorbidities. These findings may have impact on future decision-making on funding and reimbursement of bariatric surgery in Tunisia.

Back to Work After Bariatric Surgery? A Belgian Population Study. Obes Surg 2022; 32:2625-2631. [PMID: 35705782 DOI: 10.1007/s11695-022-06118-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 05/13/2022] [Accepted: 05/24/2022] [Indexed: 11/27/2022]
Abstract
INTRODUCTION Aside from an impact on health, obesity is also associated with higher social and economic costs such as impaired productivity, increased work absenteeism, and higher rates of unemployment. The aim of this study was to assess the effect of bariatric surgery on employment status in a large nationwide database, using data from all patients that underwent bariatric surgery in Belgium. METHODS This is a retrospective analysis of all Belgian patients that underwent bariatric surgery between 2014 and 2015. The work status of these patients was examined yearly: 4 years before and 3 years after surgery. Increased employment after surgery was defined (1) as a reduction in days of unemployment and incapacity and (2) as the resumption of work among the unemployed. RESULTS In total, 16,276 patients were included. The number of working people rose from 49.7% before to 61.2% 3 years after bariatric surgery, i.e., an increase of 11.5% between pre- and post-surgery. The largest improvement in reduction in unemployment was found in individuals who were absent from work for more than 9 months, namely, a reduction from 13.4 to 7.2%. In the population of unemployed patients, 20.9% became employed after bariatric surgery. CONCLUSION We found an increase in employment rate and a decrease in work incapacity and unemployment after bariatric surgery. Higher rates of employment after bariatric surgery may also contribute to an increased cost-effectiveness of bariatric surgery. It would be interesting to research possible targeting strategies to increase the employment rate even more after bariatric surgery.

Abstract
Artificial intelligence (AI) is a revolution in data analysis with emerging roles in various specialties and with various applications. The objective of this scoping review was to retrieve current literature on the fields of AI that have been applied to metabolic bariatric surgery (MBS) and to investigate potential applications of AI as a decision-making tool of the bariatric surgeon. Initial search yielded 3260 studies published from January 2000 until March 2021. After screening, 49 unique articles were included in the final analysis. Studies were grouped into categories, and the frequency of appearing algorithms, dataset types, and metrics were documented. The heterogeneity of current studies showed that meticulous validation, strict reporting systems, and reliable benchmarking are mandatory for ensuring the clinical validity of future research.

Abstract
This systematic review aimed to comprehensively synthesize cost-effectiveness evidences of bariatric surgery by pooling incremental net monetary benefits (INB). Twenty-eight full economic evaluation studies comparing bariatric surgery with usual care were identified from five databases. In high-income countries (HICs), bariatric surgery was cost-effective among mixed obesity group (i.e., obesity with/without diabetes) over a 10-year time horizon (pooled INB = $53,063.69; 95% CI $42,647.96, $63,479.43) and lifetime horizon (pooled INB = $101,897.96; 95% CI $79,390.93, $124,404.99). All studies conducted among obese with diabetes reported that bariatric surgery was cost-effective. Also, the pooled INB for obesity with diabetes group over lifetime horizon in HICs was $80,826.28 (95% CI $32,500.75, $129,151.81). Nevertheless, no evidence is available in low- and middle-income countries. ![]()

Abstract
PURPOSE This study aimed to assess outcomes of bariatric surgical procedures after the implementation of an enhanced recovery after bariatric surgery protocol in the National Bariatric Centre in Ireland. MATERIALS AND METHODS Data on consecutive bariatric procedures performed over a 36-month period was prospectively recorded. ERABS interventions utilized included preoperative counselling, shortened preoperative fasts, specific anaesthetic protocols, early postop mobilization and feeding, and extended post-discharge thromboprophylaxis. RESULTS A total of 280 primary bariatric procedures were performed over a 36-month period. The primary procedures were laparoscopic sleeve gastrectomy (57.5%), laparoscopic one anastomosis gastric bypass (33.2%) and laparoscopic Roux-en-Y gastric bypass (9.3%). Mean (SD) age was 48 (± 10) years, mean (SD) preoperative BMI 49.5 (± 9) kg/m2 and 68% were female. Median ASA score was 3, and median OSMRS also 3. Over 50% of patients had a diagnosis of hypertension or OSA, and over one-third had a diagnosis of type 2 diabetes mellitus or dyslipidemia. All procedures were completed laparoscopically and 29 patients underwent a simultaneous procedure. The mean (SD) length of stay was 2.3 (± 1.4) days (median 2 days, range 2-47 days). Overall postoperative morbidity rate was 10.0% (n = 29). The 30-day readmission and reoperation rates were 3.6% and 2.5% respectively. There was no mortality recorded in this series. CONCLUSION Implementing an ERABS protocol was feasible, safe, associated with low morbidity, no mortality, acceptable LOS and low readmission and reoperation rates. Although patients with obesity have a spectrum of disease-related complications, this should not preclude the use of an ERABS protocol in bariatric surgery.

Bariatric surgery is a cost-saving treatment for obesity-A comprehensive meta-analysis and updated systematic review of health economic evaluations of bariatric surgery. Obes Rev 2020; 21:e12932.

Abstract
Demand for bariatric surgery to treat severe and resistant obesity far outstrips supply. We aimed to comprehensively synthesise health economic evidence regarding bariatric surgery from 1995 to 2018 (PROSPERO registration number: CRD42018094189). Meta-analyses were conducted to calculate the annual cost changes "before" and "after" surgery, and cumulative cost differences between surgical and nonsurgical groups. An updated narrative review also summarized the full and partial health economic evaluations of surgery from September 2015. N = 101 studies were eligible for the qualitative analyses since 1995, with n = 24 studies after September 2015. Quality of reporting has increased, and the inclusion of complications/reoperations was predominantly contained in the full economic evaluations after September 2015. Technical improvements in surgery were also reflected across the studies. Sixty-one studies were eligible for the quantitative meta-analyses. Compared with no/conventional treatment, surgery was cost saving over a lifetime scenario. Additionally, consideration of indirect costs through sensitivity analyses increased cost savings. Medication cost savings were dominant in the before versus after meta-analysis. Overall, bariatric surgery is cost saving over the life course even without considering indirect costs. Health economists are hearing the call to present higher quality studies and include the costs of complications/reoperations; however, indirect costs and body contouring surgery are still not appropriately considered.

Abstract
Introduction Due to the constantly growing demand for surgical treatment of obesity, it is necessary to create new bariatric centers and further improve presently active ones. Aim To identify which stages of conducting peri-operative care and organizing a modern bariatric center currently pose the greatest challenge. Material and methods An anonymous survey was designed and distributed to bariatric surgeons. Our questionnaire was divided into three parts: demographic characteristics, difficulties associated with peri-operative care for bariatric patients (assessed on a scale of 1-5) and difficulties associated with organization or running of bariatric centers in which participants are currently working (assessed on a scale of 1-5). Results Overall, 70 surgeons and surgical residents from 17 surgical centers participated in our survey. The most difficult element of the pre-operative care was compliance with the recommendation to cease smoking (3.47 ±1.28). The most difficult obstacle during the postoperative care period was implementation of the enhanced recovery after surgery (ERAS) protocol (2.27 ±1.31). Funding for the bariatric treatment was obtained exclusively from the National Health Fund by 60 (85.7%) respondents working in 15 different bariatric centers (88.2%). Among elements of bariatric infrastructure access to operating theater equipment sized for morbidly obese patients was reported to be the most difficult (3.8 ±1.68). Conclusions Pre-operative recommendations including smoking, physical activity or weight loss, as well as introducing ERAS protocol based peri-operative care, are difficult to execute in bariatric departments. Future specialized bariatric centers should be included in the centralized register and equipped with specialized infrastructure for morbidly obese patients.
