Background: We assessed the cost-effectiveness of bariatric surgery (BS) versus conservative management (CM) for treating morbid obesity in Spain.
Methods: We developed a probabilistic Markov model to estimate health outcomes, quality-adjusted life years (QALY), life years gained (LYG), and costs over lifetime and 10-year horizons. Combined common BS procedures were compared with CM. Clinical and utility inputs were obtained from the literature and resource use and costs from local sources (€2017).
Results: Over the 10-year horizon, BS led to a cost increment of €9,386 and 1.6 additional QALY (€5,966/QALY). Leading to 0.6 LYG and 4.4 QALY gains and €300/patient average cost savings over lifetime, BS could potentially significantly reduce diabetes and cardiovascular disease risk over the considered horizons. Despite short-term cost reductions, surgery delay may lead to significant clinical benefits loss.
Conclusions: Compared to CM, BS is a more effective and less costly alternative for treating morbid obesity in Spain.

Background: Metabolic-bariatric surgery (MBS) transcends weight loss and offers wide-ranging health benefits, including positive effects on brain function. However, the mechanisms behind these effects remain unclear, particularly in the context of significant postoperative changes in the inflammatory profile characteristic of MBS. Understanding how inflammation influences postoperative brain function can enhance our decision-making on patient eligibility for MBS and create new opportunities to improve the outcomes of this popular treatment.

This study evaluates the feasibility of ChatGPT-4 as a knowledge resource in bariatric surgery. Using a problem set of 30 questions covering key aspects of bariatric care, responses were reviewed by three bariatric surgery experts. ChatGPT-4 achieved strong performance, with 50% of responses scoring the highest possible rating for alignment with clinical guidelines.

Background: Roux-en-Y gastric bypass may present long-term complications that require revisional surgery or even reversal to normal anatomy. Data on the indications, surgical technique, and outcomes of RYGB reversal remain scarce.
Methods: We identified 48 cases of RYGB reversals with complete 90-day follow-up within a multi-centric international retrospective database of elective secondary bariatric surgery.
Characteristics and Clinical Outcomes of Women with Polycystic Ovary Syndrome After Bariatric Surgery.

January 2025
Center for Health Policy and Health Services Research, Henry Ford Health System, Detroit, MI, USA.
Background: Polycystic ovary syndrome (PCOS) commonly co-occurs with obesity, medical comorbidities, and psychiatric symptoms. Bariatric surgery is an effective treatment for co-occurring obesity and PCOS. While the incidence of PCOS declines substantially after bariatric surgery, the condition is still present for a subset of women.
