Unveiling the cost-effectiveness of bariatric surgery: insights from a matched cohort study.
Surg Obes Relat Dis
September 2025
Background: Obesity is a global health problem with alarming rates of morbidity and mortality. Although bariatric surgery is a proven safe and effective treatment for obesity, only a small fraction of eligible patients utilizes it.
Objectives: Assess the economic impact of bariatric surgery costs within 2 years of the index date and identify factors associated with cost differences.

Scientific evidence for the updated guidelines on indications for metabolic and bariatric surgery (IFSO/ASMBS).
Surg Obes Relat Dis
November 2024
The 2022 American Society for Metabolic and Bariatric Surgery (ASMBS) and International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) updated the indications for metabolic and bariatric surgery (MBS), replacing the previous guidelines established by the National Institutes of Health (NIH) over 30 years ago. The evidence supporting these updated guidelines has been strengthened to assist metabolic and bariatric surgeons, nutritionists, and other members of multidisciplinary teams (MDTs), as well as patients. This study aims to assess the level of evidence and the strength of recommendations compared to the previously published criteria.

- The ASMBS and IFSO updated the guidelines for Metabolic and Bariatric Surgery in 2022, replacing 30-year-old NIH recommendations.
- These new guidelines are based on stronger evidence and are designed to support healthcare professionals and patients in making informed decisions about surgery.
- The study evaluates the quality of evidence and the effectiveness of these updated recommendations compared to the old criteria.
Article Synopsis
- The study highlights the increasing importance of metabolic and bariatric surgery (MBS) in addressing global obesity, emphasizing the need for rigorous academic and fellowship training for surgeons.
- A Modified Delphi method involving 89 surgeons from 42 countries was used to establish expert consensus on the necessary criteria for surgeons to obtain privileges for performing MBS, reaching agreement on 29 out of 30 statements.
- Key consensus points include the requirement for surgeons to hold a general surgery degree, complete a dedicated fellowship, and adhere to defined learning curves for various MBS procedures, alongside maintaining patient data and collaborating in a multidisciplinary team.
Background: With the implementation of the 11th edition of the International Classification of Diseases (ICD-11) and the publication of the metabolic dysfunction-associated fatty liver disease (MAFLD) nomenclature in 2020, it is important to establish consensus for the coding of MAFLD in ICD-11. This will inform subsequent revisions of ICD-11.
Methods: Using the Qualtrics XM and WJX platforms, questionnaires were sent online to MAFLD-ICD-11 coding collaborators, authors of papers, and relevant association members.
Background: Metabolic and bariatric surgery (MBS), despite being the most effective durable treatment for obesity, remains underused as approximately 1% of all qualified patients undergo surgery. The American Society for Metabolic and Bariatric Surgery established a Numbers Taskforce to specify the annual rate of obesity treatment interventions utilization and to determine if patients in need are receiving appropriate treatment.
Objective: To provide the best estimated number of metabolic and bariatric procedures being performed in the United States in 2022.
Objective: This study aimed to survey international experts in metabolic and bariatric surgery (MBS) to improve and consolidate the management of biliary disease in patients with severe obesity undergoing MBS.
Background: Obesity and rapid weight loss after MBS are risk factors for the development of gallstones. Complications, such as cholecystitis, acute cholangitis, and biliary pancreatitis, are potentially life-threatening, and no guidelines for the proper management of gallstone disease exist.
Article Synopsis
- * A study using a consensus method involved 78 bariatric surgeons globally, who agreed on 54 statements regarding when to use MBS for Class I and II obesity, determining a 70% agreement threshold.
- * The experts concluded that MBS is cost-effective for Class II obesity and Class I obesity with inadequate weight loss from non-surgical methods, and identified specific surgical options including intra-gastric balloon, endoscopic sleeve gastroplasty, sleeve gastrectomy, Roux-en-Y gastric bypass, and one
Article Synopsis
- The study surveyed international experts to improve prevention strategies for gastroesophageal reflux disease (GERD) and marginal ulcers (MU) following metabolic and bariatric surgery (MBS).
- Over 90% of experts recommend postoperative acid suppression, with a significant majority also advocating for lifetime proton pump inhibitors for certain patients and routine Helicobacter pylori eradication prior to surgery.
- The findings highlight a general agreement on key interventions but reveal variability in follow-up practices and management strategies, indicating a need for more research and standardized guidelines.
Literature review on antiobesity medication use for metabolic and bariatric surgery patients from the American Society for Metabolic and Bariatric Surgery Clinical Issues Committee.
Surg Obes Relat Dis
September 2022
The following literature search is in response to inquiries made to the American Society for Metabolic and Bariatric Surgery (ASMBS) regarding antiobesity medication (AOM) use in patients who are having or have already had metabolic and bariatric surgery (MBS). These recommendations are based on current clinical knowledge, expert opinion, and published peer-reviewed scientific evidence available at this time. This paper is not intended to establish a local, regional, or national standard of care.

Video self-assessment augments development of videoscopic suturing skill.
J Am Coll Surg
November 2009
Background: Development of surgical skills on inanimate models has been popularized by efforts to improve patient safety and efficiency of resident training. We evaluated whether surgical residents' acquisition of videoscopic suturing skill is accelerated by reviewing video of their own previous practice session.
Study Design: Fourteen residents from two general surgery training programs received didactic instruction on laparoscopy.
