Patients with hepatopancreatobiliary diseases in the perioperative period are prone to significant blood glucose fluctuations due to organ dysfunction, stress responses, and concurrent diabetes mellitus. Traditional fingertip blood glucose testing has limitations such as fragmented monitoring and lag time, which can easily lead to missed detection of hypoglycemia or hyperglycemia, thereby increasing surgical risks and complication rates. Flash Glucose Monitoring (FGM), as an advanced glucose monitoring technology, enables continuous, real-time glucose tracking for over 72 hours, accurately capturing glucose fluctuation patterns and providing a scientific basis for individualized perioperative glycemic management. This paper systematically reviews the principles of FGM technology and its current application status in the preoperative evaluation, intraoperative monitoring, and postoperative care of hepatopancreatobiliary diseases. It analyzes the clinical advantages and existing challenges of FGM, and discusses future application directions in the context of the precision nursing trend. This review aims to provide a reference for improving the quality of perioperative glycemic management and enhancing patient outcomes.
