After colon cancer surgery, there are two kinds of cases: with stoma and without stoma, and the bowel movement is also different. If there is no stoma in the abdominal wall, it is the same as normal people, and the bowel movement is through the anus, because after colon cancer surgery, there is no exhaustion and bowel movement at the beginning, and about 2 days after surgery, the patient has bowel movement, which is relatively thin and unformed at first. When the stool is basically formed 5 days after surgery, it is recommended to defecate on the toilet as much as possible. If there is a stoma in the abdominal wall after colon surgery, a stoma is routinely made in the lower left abdomen, and stool comes out of the stoma, so care of the stoma is needed, and there may be stool at any time.
