Applications in Gynecology with Emphasis on the Cervix

  • Joseph H. Bellina

The bioeffects of the CO2 surgical laser have been described; it is now necessary to examine the advantages of this new surgical tool which have allowed the development of its practical applications in surgery, and how its biophysical properties may be used advantageously (Table 4.1). The surgeon can easily learn this new technique with training and practice. When one uses a knife, the depth of incision is controlled by the pressure applied to the scalpel. In contrast, using a laser instrument is a unique experience: the tissue is not touched and the desired effects are obtained by varying the biophysical parameters (Table 4.2) in freehand surgery as well as microscopic surgery. Precise power and beam spot size settings, appropriate speed of incision, and control of secondary burn effects from the heat energy of the beam by cooling methods are necessary for optimizing laser techniques. In spite of the disadvantage cited in Table 4.3, the precision of the laser instrument allows more conservative surgery and the characteristic of the hemostatic incision, with its self-sterilizing operative field, must be considered of essential importance in modern general surgery and especially useful for gynecologic applications (Table 4.4). The broad spectrum of continuous power output setting and exposure time allows the surgeon high flexibility of application. Laser surgery usually requires a combination of coagulation, excision, and vaporization techniques.
