Not : Not all colorectal cancer surgeries requires a colostomy. A colostomy is more often needed during an emergency operation (when there is no time to clean the bowel properly before the operation), like perforation or obstruction of the bowel caused by the tumor, that can create contamination and infections inside the abdomen. In those conditions putting the bowel together could be very risky and lead to failure of the operation, and doing a colostomy would help to control the contamination and prevent further infection. Commonly, after four to six weeks it is then safe to put the bowel together. On the other hand, if a colorectal cancer is detected in an early stage and no emergency situations are present, the bowel can be prepared properly and put together with less chances of having a complication. However, even in ideal conditions, some times the surgeon can find situations during the surgery which are concerning for possible complications (like poor blood supply to the bowel) and a temporary colostomy is performed to protect the bowel connection and let it heal safely without the passage of stool. Finally, some colostomies are permanent, depending on the location, the size, or the extension of the tumor to other organs.
