Laparoscopic Surgery

A '' Laparoscope '' consists of a Hopkins rod Lens system , that is usually connected to a Video camera- single chip or three chip, a Fibre Optic cable system connected to a 'cold' light source, Halogen or Xenon , to illuminate the operative field, inserted through a 5 mm or 10 mm canula to view the operative field. Additional 5- 10 mm thin instruments can be introduced by the Surgeon through side ports. Rather than a 20 cm cut as in traditional Cholecystectomy , two to five cuts of 5-15 mm will be sufficient to perform a laparoscopic removal of a gallbladder. The Abdomen is usually insufflated with Carbon Dioxide gas to create a working and viewing space.

This approach, pioneered by Dr. Camran Nezhat , is intended to minimise operative blood loss and post-operative Pain , and speeds up recovery times. However, in some cases the pain caused by the carbon dioxide leaving the body is severe and painkillers have little or no effect. The restricted vision, difficult handling of the instruments (hand-eye coordination), lack of tactile perception and the limited working area can increase the possibility of damage to surrounding organs and vessels, either accidentally or through the difficulty of procedures.

The First Transatlantic Surgery (Lindbergh Operation) ever performed was a laparoscopic gallbladder removal.

RISKS

Some patients have sustained electrical burns unseen by surgeons who are working with Electrode s that leak current into surrounding tissue. The resulting injuries can result in perforated organs and lead to Peritonitis .
