What is the pain in the right upper abdomen and the ultrasound does not show any abnormality? The important organs in the right upper abdomen are the liver and gallbladder, and most of the pain in the right upper abdomen is due to cholecystitis, gallstones, or liver lesions, such as hepatitis, etc., all of which can cause pain in the right upper abdomen. Ultrasound can find abnormalities, such as gallbladder wall roughness, suggesting cholecystitis; in addition to gallstones, ultrasound can make a clear diagnosis; if there is hepatitis or cirrhosis, or other lesions of the liver, ultrasound can make a diagnosis accordingly. If there is no abnormality, it is likely that there is no organic lesion, that is, gastrointestinal dysfunction or intestinal obstruction, enteritis, etc. If there is intestinal obstruction, we should carry out the relevant emergency treatment, and if it is only enteritis, gastrointestinal dysfunction or intestinal spasm, it can be treated with medication.
