Intestinal deformation is manifested by pouch elimination, narrowing of the intestinal lumen and shortening of the intestinal canal. It is obvious in the acute stage, and as the inflammation subsides, some of the pouch shape can be restored, but it is difficult to restore the unnamed grooves on the mucosal surface, etc. It is a primary mesenteric tumor incidence although not high, mostly seen in men, male to female ratio is 3:2 or 2:1, can occur at any age, but individual tumors of embryonic tissue residual origin, so,how to diagnose whether the intestinal canal deformation? If the patient has the following symptoms, it can be diagnosed as intestinal tube deformation: 1, abdominal mass: it is the earliest and most frequent symptom, often found when feeling abdominal discomfort or abdominal distension, but also because the abdominal mass is very small, without conscious grasping, mostly found during physical examination, the mass can be cystic or substantial. If its texture is hard, the surface is not light, nodular and has pressure pain, often suggest malignant swelling. 2. Pain: It is also a common early symptom, which is mostly distension and discomfort. If the tumor invades the intestinal canal or the tumor activity of both sexes is large, it can cause partial intestinal obstruction, then there is paroxysmal pain, and the spontaneous rupture of the tumor can cause acute peritonitis and other severe pain. The pain often prompts the patient to seek medical treatment early. Fever: Mostly seen in malignant tumors, the first symptom of common lymphosarcoma in many patients is unexplained fever. Some benign lymphangioleiomyosarcomas may also develop high fever when secondary infection occurs. Highly malignant soft tissue sarcoma with rapid growth, secondary infection after partial necrosis and tumor toxin reaction can lead to irregular fever or low.
