High Anterior Resection
This is an operation to remove part or all of the rectum. It is most usually performed for patients with rectal cancer. Many patients with rectal cancer will have radiotherapy before the operation.
Anterior resection is sometimes performed for patients with diverticular disease. In many cases the operation can be performed via alaparoscopic (keyhole) surgical technique.
This operation can be performed as an open or laparoscopic (keyhole procedure). During the operation part, or all of the rectum is removed, usually with part of the sigmoid colon. This involves taking away the blood vessels and lymph nodes to this part of the bowel. The surgeon then re-makes the join (anastomosis) between the remaining colon and the remaining part of the rectum. The surgeon may use sutures or special staples to make this join. If there are any special circumstances that mean that a stoma (usually an ileostomy) may be required the surgeon will discuss this possibility beforehand.
The operation time may vary for this type of surgery but is usually around 3-4 hours.
