What kinds of intestinal conditions require surgery?
The common conditions that end up requiring surgery within the abdomen, particularly relating to the large and small bowel, are colon and rectal cancer, diverticulitis, and inflammatory bowel disease, such as Crohn's disease and ulcerative colitis.
What is the difference between open surgery and laparoscopic surgery?
Traditionally, abdominal surgery has been performed in an open manner, and what that means is the patient has a reasonably large incision, which varies in size between four and 10 inches long. It's usually in the midline of the abdomen, so it runs from the pubis at the lower midline of the abdomen up to the navel. The length depends on the extent of surgery and the extent of bowel that one has to free up or take out.
When the surgery's performed laparoscopically, we put in three or four access ports, which are little plastic tubes that go into the abdomen that are positioned through incisions less than half-an-inch long. Then through these access ports we put in a camera, which is less than a half-inch in diameter, which is used to see what's going on inside the abdominal cavity. Through the other access ports we put in very fine little surgical instruments, about 5 millimeters in diameter. We use those instruments to free up the bowel and then we make an incision of four to six centimeters in size (around two inches) to remove the bowel.
