The article examines the role of ultrasound examination (USI) as a key method for assessing the condition of patients with non-alcoholic fatty liver disease (NAFLD) within the context of surgical treatment. The possibilities of ultrasound in preoperative planning are described, particularly in bariatric surgery, where the volume of the left lobe of the liver determines the technical complexity of access. Attention is paid to elastometry as a non-invasive method for assessing fibrosis, which allows for predicting the risk of intraoperative bleeding. The significance of ultrasound monitoring in the postoperative period is analyzed to assess the regression of steatosis. It was concluded that ultrasound is a necessary standard that ensures the safety of surgical intervention and the objectivation of treatment results.
