Ultrasound is not useful for examining solid organs of the abdominal cavity, such as the liver, gallbladder, pancreas, spleen, kidneys, ureters, bladder, prostate and uterine adnexa, regardless of whether the disease is acute or chronic. Diseases of the digestive tract, including enteritis or gastritis, require gastrointestinal endoscopy to make a diagnosis. If there are obvious clinical symptoms of enteritis, such as abdominal pain, changes in stool, including changes in stool characteristics, stool color, stool habits, etc., it is necessary for the patient to go to the hospital and cooperate with the doctor to improve the e-colonoscopy, as appropriate. The actual diet of the patient with enteritis also needs to pay attention to a light diet, to develop good eating habits.
