This operation can be performed as an open or laparoscopic (keyhole procedure). During the operation the whole of the colon, and the last part of the small intestine are removed. This involves taking away the blood vessels and lymph nodes to that part of the bowel. The surgeon then re-makes the join (anastomosis) between the small intestine and the remaining part of the colon/rectum. The surgeon may use either sutures or special staples to make this join. If there are any special circumstances that mean that a stoma may be required the surgeon will discuss these issues beforehand.
Sometimes in the case of Crohn’s disease or ulcerative colitis, a join will not be made and the small intestine will be used to form an ileostomy.
The remaining bowel (rectum) is closed off and left inside.
The operation time may vary for this type of surgery but is usually around 3 hours.
The piece of bowel that is removed is sent to the pathology department where the pathologist carefully examines it. The results are usually available within two weeks of the operation.
