Abstract:Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age and is closely associated with obesity. In recent years, the role of bariatric and metabolic surgery in improving obesity complicated with PCOS has gradually attracted attention. The Metabolic Disease Professional Committee of the Chinese Medical Education Association, Chinese Society of Thyroid and Metabolism Surgery, Chinese Society of Surgery, Chinese Medical Association, Chinese Society for Metabolic & Bariatric Surgery, Chinese College of Surgeons, Chinese Medical Doctor Association, and the National Key Laboratory of Reproductive Medicine and Offspring Health jointly developed this consensus based on the latest domestic and foreign guidelines, clinical research evidence, and expert opinions. In the consensus, the diagnostic criteria, preoperative evaluation, surgical indications, selection of surgical methods, perioperative management, and postoperative PCOS follow-up are recommended to provide standardized guidance for bariatric metabolic surgery for obese patients with PCOS.
