Bowel cancer is a relatively common malignant tumor of the digestive tract in the clinic. Whether the surgery for bowel cancer is very large or relatively small depends on the pathological stage of bowel cancer and the patient’s treatment plan. If bowel cancer is treated by radical treatment and radical surgery is performed for bowel cancer, the surgery is relatively large, the trauma of the patient is more serious, and the postoperative recovery is slower. However, some bowel cancers are in advanced or middle end stage, it is not a big deal to do palliative surgery, just do pure local tumor resection. Distal or proximal for enterostomy, to solve the obstruction to relieve the patient’s abdominal distension, intestinal obstruction and other symptoms, such a surgery is moderately small surgery, although the blow to the patient is not big, but the patient’s postoperative and prognosis are very poor, which may easily lead to the emergence of more metastatic foci in a short period of time after the operation and endanger the life.
