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, mostly seen in children and adolescents, most primary mesenteric tumors originate from mesenchymal tissue and neural tissue, among which lymphosarcoma has the highest incidence. Barium meal examination and barium enema angiography can indirectly show the site and size of tumor, intestinal tube deformation and displacement, etc. So, what should be done to prevent and treat intestinal canal deformation? Firstly, it is advisable to diversify diet, develop good eating habits, not to be partial or picky, not to consume high-fat and high-protein diet for a long time, and often eat fresh vegetables containing vitamins and fiber, which may have an important role in preventing cancer. Secondly, prevent constipation and keep bowel movement smooth. Finally, attach great importance to regular cancer screening, and pay attention to self-examination at all times to enhance vigilance. After discovering the “warning signs”, timely diagnosis and treatment are needed to achieve early detection and early treatment to prevent the development of rectal cancer.
