Laparascope (definition of)

The laparascope is a device used in laparoscopic surgery, a minimally invasive procedure that is performed through small incisions. It is a subspecialty within the field of endoscopy. Laparascopy can be performed for diagnosing diseases like mesothelioma.

There are two types of laparascope. One of these consists of a telescopic rod lens connected to a video camera: the other is a digital device for which the camera is placed at the end, eliminating the need for a rod lens. Illumination of the operative field is done with a halogen or xenon light through a fiber optic cable.

Although laparascopy represents cutting-edge technology, it traces its origins back well over a century; the technique was first used be a German veterinarian in 1902, and the first successful operation on a human was done in Sweden about a decade later. However, it was not until 2002 that laparascopy was first used successfully in a "remote" operation with the surgeons in one place and the patient in another. This was the "Lindbergh" operation, during which French surgeons in New York City performed an operation on a patient in Strasbourg.

This type of surgery has several advantages over conventional techniques, but is not without its risks. On one hand, there is reduced hemorrhaging, less pain and less chance of infection. On the other hand, because the initial opening is made blindly, there is a chance of internal injuries that are not immediately apparent and can lead to life-threatening conditions later on.

Mesothelioma patients should consult with their doctors to see if laparoscopic surgery is appropriate for their cancer prognosis.
