Clinically, if a patient presents with vague pain in the lower right corner, it is important to see if the patient has any respiratory-related symptoms. For example, if the patient has any respiratory-related pain, is it accompanied by corresponding symptoms such as cough, dyspnea, and pain on local pressure. If so, a CT lung examination is performed. Clinical diseases of the lungs, such as pleurisy, pneumothorax, or problems with the sternum of the lungs may also cause similar symptoms and require an examination to refine them. In addition to the above diseases, if there are no above symptoms, the greatest clinical possibility is still caused by hepatobiliary problems. This is because in terms of anatomical location, the right upper abdomen is most commonly associated with hepatobiliary problems. Clinically, for example, common fatty liver, chronic cholecystitis, gallbladder stones, intrahepatic bile duct stones, or problems in the stomach can cause similar symptoms. Therefore, clinically, depending on whether the patient has a dietary correlation, gastroscopy or hepatobiliary, pancreatic and splenic ultrasound is done to give a clear diagnosis. After the diagnosis is made, the patient can be given precise treatment.
