These surgeries can be done using one of two techniques: laparoscopy or laparotomy.
With this technique, an instrument equipped with a small camera and light is used to let the surgeon clearly see inside the abdominal cavity.
The surgeon makes 3 to 5 small incisions (cuts) in the abdomen that are 1 to 2 centimetres long and also makes one 5-to-7 centimetre incision to remove the diseased part of the intestine. During the surgery, carbon dioxide is pumped into the abdomen to expand its walls and let the surgeon see into the cavity. The gas is then pumped out after the surgery.
With this technique, the surgeon opens the abdominal wall with a 10- to 20-centimetre vertical or horizontal incision.
There are different types of colorectal surgeries. The images below show the part of the bowel (outlined in black) that is removed in each procedure.
