Classification based on the 2021 Abdominal Ultrasonography Examination Judgment Manual (Revised Edition) was examined in 1,521 patients who underwent physical examination by abdominal ultrasonography from April 2021 to March 2022. The results showed that the liver had the highest prevalence of findings by organ (76.0%), with fatty liver being the most common (581 cases). Follow-up of 32 patients with a thorough examination revealed that 20 of these patients had results that were concordant between the examination and ultrasonography, with the most common lesion being intraductal papillary mucinous neoplasm (IPMN), a pancreatic disease. In the 12 cases with discordant or normal results on a close examination, the most common findings were hepatic hemangioma and common bile duct dilation. The results of the study suggest that improvement of skills is needed to observe target organs in a short time using ultrasonography and to avoid missing lesions that require close examination, even if they can be visualized.
