Many operations previously performed with the traditional (open) surgery can now be done with the minimally invasive approach. While traditional surgery requires a large abdominal incision, minimally invasive surgery only requires small incisions that are about the width of a button hole (5-10 mm). Minimally invasive surgery uses highly specialized equipment to perform complex surgical operations through these tiny incisions. A miniature video camera with a fiberoptic lens is used to visualize the precise details of the operation in the abdomen. Long, thin instruments are passed through access ports to perform these focused surgeries. Carbon dioxide is introduced into the abdomen to create a working space for the operation, and is removed upon completion. Because of the smaller incisions, less tissue is disturbed resulting in a quicker recovery and less pain.
