title: The three-dimensional video system; an essential component of the endosurgical suite of the future.
abstract: Minimal access surgery has revolutionized the practice of surgery. It has been shown that patients may experience less postoperative discomfort, shorter hospitalization, and quicker recuperation. The centerpiece of this revolution resides in the development of optical equipment which allowed the surgeon and his or her assistants to visualize on two-dimensional (2-D) monitors the site of the procedure to be performed. However, as techniques become more complicated, there is more need for accurate depth perception. In other surgical disciplines like neurosurgery, otorhynolaryngology, and microvascular surgery, for instance, magnification is used to perform fine manipulations; to prevent loss of depth perception, microscopes are binocular. They permit stereoscopic vision with accurate depth perception. We have used and evaluated a three-dimensional (3-D) videocamera system, designed for laparoscopy, in an in vitro situation, in the experimental laboratory and clinically, and we report our experience in this chapter. We also discuss the rationale for use of 3-D video systems.
