How Keyhole Surgery works
Keyhole surgery uses an instrument called a laparoscope. It is a small, narrow tube that has both a light source and a camera on it, which illuminates and feeds back images of inside the body to a screen in the operating room. The size of the laparoscope means that it can be fed into the body through a small, keyhole-sized incision.
As well as being a diagnostic tool, the laparoscope also makes it possible for surgeons to perform some types of surgery through the same incision. Narrow, surgical tools can be inserted through small incisions into the area, while the camera feeds back the images so that the surgery can be performed accurately, and just as if the surgeon were seeing it with his own eyes.
Keyhole surgery is generally carried out under a general anesthetic, meaning that you will not be in any pain during the procedure, or have any recollection of the procedure.
Thankfully, an increasing number of surgeries can now be performed laparoscopically, including surgeries for:
• Colon conditions
• Ulcerative colitis
• Restorative proctocolectomy
• Gastrointestinal malignancies
• Some tumors
• Groin pain
• Gastrointestinal bleeding
