Minimally Invasive Surgery

Minimally Invasive Surgery Informational pdf

Laparoscopic surgery, also called minimally invasive surgery or keyhole surgery, is a modern surgical technique in which operations in the abdomen are performed through small incisions (usually 0.5–1.5 cm) as opposed to the larger incisions needed in laparotomy.

Keyhole surgery makes use of images displayed on TV monitors to magnify the surgical elements. The main element in laparoscopic surgery is the use of a laparoscope. laparo sx

The laparoscope has a telescopic rod lens system, that is connected to a video camera Also attached is a fiber optic cable system connected to a ‘cold’ light source to illuminate the field.

The abdomen is usually insufflated, or essentially blown up like a balloon, with carbon dioxide gas. This elevates the abdominal wall above the internal organs like a dome to create a working and viewing space. CO2 is used because it is common to the body and can be absorbed by tissue and removed by the respiratory system.

• Reduced hemorrhaging, which reduces the chance of needing a blood transfusion.
• Smaller incision, which reduces pain and shortens recovery time, as well as resulting in less post-operative scarring.
• Less pain, leading to less pain medication needed.
• Reduced exposure of internal organs to possible external contaminants thereby reduced risk of acquiring infections.
