The survival period after stoma surgery needs to be analyzed objectively according to the different primary diseases of patients, as follows: 1. If the patient is suffering from inflammatory bowel obstruction due to intestinal tract with a large amount of dry and knotted fecal blockage, or the tumor reaches radical resection. After 3-6 months, the inflammation in the abdominal cavity is completely controlled and the stoma can be returned to the patient, which will not cause serious impact on the patient’s life; 2. If the patient has advanced malignant tumor of sigmoid colon or rectum, which causes a large amount of tumor proliferation, completely blocking the intestinal canal and causing intestinal obstruction. At this time, it is difficult to perform complete surgical resection of tumor lesions and lymph node dissection, and only distal intestinal canal closure and proximal intestinal canal stoma can be performed. Since the tumor was not completely removed after the stoma, the tumor cells gradually proliferated in the body and seriously damaged the normal function of the body. The patient’s tumor belongs to the middle and late stage, and the survival time is short.
