The differential diagnosis of intestinal obstruction can be based on a combination of in-person consultation and medical imaging. The main symptoms of patients with intestinal obstruction include abdominal distension, abdominal pain, nausea, vomiting, and difficulty in defecation. The obstruction of intestinal tissues not only causes belching and the accumulation of excrement in the body, but also induces violent spasms of smooth muscles in the stomach, intestines and other digestive tract tissues, resulting in the occurrence of the above-mentioned adverse symptoms in patients. Intestinal obstruction can be diagnosed and treated with the help of medical imaging methods such as X-ray, abdominal CT scan and MRI. Through these examinations, symptoms such as abnormal dilatation of local intestinal tissues and thickening of mucosal wall tissues can be observed, and in severe cases, perforated bleeding of the intestine may even occur.
