Ultrasound is a common examination method in clinical practice, but ultrasound is generally not used for intestinal examination. Because of the influence of factors such as more gas and intestinal contents in the intestine, ultrasound observation of the intestine is not clear, and at most, we can only see whether there is appendicitis or appendiceal mass, while using ultrasound to examine other intestinal diseases is very unsatisfactory. Clinical ultrasound examination mainly includes the digestive system, mainly used to examine the liver, gallbladder, spleen, pancreas, kidneys, bladder, prostate, for the ureter, bladder, urinary system is also more applicable, thyroid, breast and other organs are also suitable for the use of ultrasound, but the use of ultrasound to examine the intestine is not as the first choice, examination of the intestine should first consider the use of colonoscopy for examination.
