Bariatric surgery aims not only to achieve satisfactory weight loss and safety for the patient, but also to improve quality of life. Studies confi rm that a short-term improvement in quality of life is observed after surgery, which is an important aspect in assessing the eff ectiveness of obesity treatment.The purpose. To assess the quality of life of patients after diff erent types of bariatric surgery. Research material and methods. The study included clinical examination and surgical treatment of 44 patients with metabolic syndrome, including 17 men and 27 women aged 47±6.75 years with a body mass index of ˃40 kg/m2. All patients were divided into three groups depending on the chosen surgical intervention tactics: laparoscopic sleeve gastrectomy (LSG) – 15 patients, laparoscopic gastroplication (LGP) – 22 patients, bariatric artery embolisation (BEA) – 7 patients. All patients provided informed consent. The quality of life (QOL) was assessed 1 year after surgery using licensed SF-36 questionnaires, which include eight QOL indicators. Postoperative assessment was associated with weight, BMI and percentage of overweight loss (% EWL). Results and their discussion. Using the SF-36 questionnaire before and after bariatric surgery, a signifi cant improvement in QOL was observed in the group of patients who underwent laparoscopic gastroplication (LGP), laparoscopic sleeve gastrectomy (LSG) and bariatric gastric artery embolisation (BEA). All three groups of patients reported improved quality of life in terms of physical and mental health after 1-year follow-up. There was also a decrease in body mass index (BMI) and percentage of overweight loss, which confi rms the eff ectiveness of various methods of bariatric surgery in achieving signifi cant weight loss and improving the quality of life of patients.Conclusion. After various types of bariatric surgery, an overall improvement in quality of life was noted, but the most signifi cant improvement was observed after laparoscopic omentectomy, which may be due to greater average weight loss in this group. In bariatric embolisation, the results are similar to laparoscopic treatment, but are characterised by less surgical trauma and the absence of postoperative adverse events that are usually associated with reductive surgery, such as nausea, vomiting and heartburn.
