Laparoscopic surgery is a minimally invasive approach to common surgical problems in the abdomen. Benefits of laparoscopic surgery include:
• Less post-operative pain
• Shorter hospital stay
• Decreased scar formation
• Faster recovery
Although the techniques vary from procedure to procedure and among different surgical subspecialties, all minimally invasive surgical procedures employ video cameras and lens systems to provide anatomic visualization within a region of the body.
Achieving such visualization requires the creation and maintenance of an optical cavity, most commonly created with carbon dioxide gas insufflation. After making small incisions in the skin, narrow tubes are inserted through the abdominal wall so that instruments can be passed through them to perform the maneuvers necessary for the operation. All this is viewed directly on a video monitor which receives its picture from a video camera attached to the laparoscope.
