CT is a non-invasive examination, and the radiation dose will not cause damage to the intestinal tract, and will not induce adhesions or even intestinal obstruction. The causes of adhesive bowel obstruction can be categorized into congenital and acquired. The principle of CT examination is to scan the human body with X-rays, and the X-rays penetrating the human body are received by the receiver, and then converted into digital signals by the converter, and then the image reconstruction is performed in the computer to get the image of the corresponding part, which is a kind of non-invasive examination, and it will not cause any physical damage to the intestinal tract, and the dose of the rays is also in the safe range of the human body, which will not lead to the radiological enteritis, and thus will not induce the intestinal adhesion or even the intestinal obstruction. It will not lead to radiation enteritis and thus will not cause intestinal adhesion or even obstruction. The causes of adhesive intestinal obstruction include congenital and acquired factors, congenital factors include congenital developmental abnormalities, peritonitis caused by meconium, which is relatively rare; acquired factors include a history of abdominal surgery, a history of extensive intra-abdominal inflammation, severe abdominal trauma and intra-abdominal hemorrhage, etc., and intra-abdominal surgery causing intra-abdominal exudative adhesion is common. Although there is a certain amount of radiation in CT examination, it is within the safe range, and standardized and reasonable examination will not cause serious side effects, so patients who have the need for examination do not need to worry too much, and in order to clearly diagnose the disease, follow the doctor’s instructions.
