Keyhole surgery, or laparoscopic surgery as it is also known, is a method of carrying out an operation without having to make a large incision. Many different types of operations can now be carried out using keyhole surgery. This type of surgery reduces the length of time a patient needs to stay in hospital and leaves little scarring.
The operation time may be longer than conventional surgery – the length of time the patient spends away from the ward may be between one and a half and four hours.
Patients tend to recover more quickly after keyhole surgery and have fewer side effects. There is little scarring after keyhole surgery which is a boon to people who are self-conscious. One side effect of ‘open’ surgery – minimised with keyhole surgery – is ‘adhesions’. This is where internal organs stick together and form bands of scar tissue, which can be painful and cause obstruction. Adhesions have been proven to occur less often in adults after keyhole surgery, and the risk of adhesions in children after keyhole surgery is thought to be less as well.
Every anaesthetic carries a risk of complications but this is very small. All anaesthetists are experienced doctors who are trained to deal with any complications. After an anaesthetic, patients sometimes feel sick and vomit, may have a headache, sore throat or feel dizzy. These effects are short-lived. Any surgery carries a small risk of infection or bleeding. After the operation, some patients may complain of shoulder pain. The patient may also feel some crackling under the skin because the carbon dioxide sometimes escapes into the tissue just under the skin. These side effects are usually short-lived and do not require any specialised care.
