What is Laparoscopic surgery?
Laparoscopic surgeryis also known as minimally invasive surgery (MIS), keyhole surgery and band-aid surgery. As compared to larger incisions needed in traditional surgical procedures, this modern surgical technique involves operations on the abdomen through small incisions (usually 0.5 - 1.5 cm).
In keyhole surgery, images displayed on TV monitors are used for magnification of the surgical elements.
Operations within the abdominal or pelvic cavities come under advanced laparoscopic surgery, whereas keyhole surgery performed on the thoracic or chest cavity is called thoracoscopic surgery. Both the surgeries, laparoscopic as well as thoracoscopic belong to the wider field of endoscopy.
As compared to open surgery, there are number of advantages to the patient with laparoscopic surgery. Due to smaller incisions and hemorrhaging, there is reduced pain and shorter recovery time.
Today there is no abdominal surgery which is not performed laparoscopically.
The Digital laparoscope
A charge-coupled device is placed at the end of the laparoscope in this digital laparoscope technique. This eliminates the use of rod lens system. A fiber optic cable system is also attached which is inserted through a 5 mm or 10 mm cannula or trocar to view the operative field. To illuminate the operative field, the cable system is connected to a 'cold' light source (halogen or xenon). Carbon dioxide gas is used for blowing up abdomen like a balloon, as it is common to the human body and can be absorbed by tissue and removed by the respiratory system. CO2 gas is also used as it is non-flammable, which is important because electrosurgical devices are commonly used in laparoscopic procedures. Other than this; the abdomen can be also insufflated. Elevation of abdominal wall above the internal organs creates a dome shaped working and viewing space.
As compared to open procedure, there are a number of advantages to patient with laparoscopic surgery. These include:
