Small incisions will be made in the abdomen. A tube will be passed through one of the incisions. It will push gas into the belly. This will make it easier for the doctor to view the area. A camera will allow the doctor to see inside the belly. Other tools will be passed through the incisions. They will be used to remove the diseased section of intestine.
