Intestinal deformation is manifested by pouch elimination, narrowing of the intestinal lumen and shortening of the intestinal canal. It is evident in the acute stage and can recover some of the pouch shape as the inflammation subsides, but the unnamed grooves on the mucosal surface, etc., are difficult to recover. It can occur at any age, but individual tumors of residual embryonic tissue origin, mainly due to long-term chronic inflammation and ulceration, lead to pouch disappearance intestinal lumen narrowing and intestinal canal shortening thus leading to intestinal canal deformation. So, is CT examination necessary for intestinal tube deformation? CT examination can not only identify tumors of intra-abdominal organs and retroperitoneal tumors from their sites of occurrence, but also detect mesenteric tumors that are relatively small in size. Benign cysts with outer envelope and intracapsular stroma showing hypodensity, round, oval or multiple irregular shapes can suggest lymphatic fistula. If there are calcified or ossified areas in the cyst, it should suggest teratoma or low-grade malignant soft tissue sarcoma. Mesenteric tumors with higher malignancy on CT images show soft tissue density shadows, and whether the surrounding tissues and organs are invaded by them can be clearly seen. In particular, the relationship between the intestinal canal and blood vessels and the tumor is very clear, which has a high reference value for determining whether the tumor can be resected before surgery, and can be used for follow-up to evaluate the effect of treatment and to know whether it recurs. Other methods, such as lymphography and laparoscopy, have some significance in the diagnosis of intestinal deformation, but they still depend on surgical exploration, so they are not recommended.
