Laparoscopy (also known as "Keyhole surgery") is a surgical technique used to examine internal cavities in the body such as the brain, abdominal and pelvic cavities. A small incision of 0.4-0.6 inches is used. A Laparoscope is a tube that contains a small camera which sends live videos to the screen in the operating room. This makes it easy for examination and diagnosis to be made instantly.
Before the development of keyhole surgery, incisions large enough to provide wide access to internal organs were used. These large incisions prolonged recovery time and increased risks of wound infection, unlike laparoscopic surgeries which do the opposite (reduce recovery time and lower chances of infection). Other benefits of minimally invasive or laparoscopic procedures include less postoperative discomfort and less internal and external tissue scarring.
