Bipolar electrosurgery can be superior to monopolar electrosurgery for certain neurosurgical and ophthalmic applications that require a "wet" surgical field. Bipolar electrosurgery, however, is not an effective method for electrosurgically cutting tissue, nor can it be used to stop bleeding over a large area, and thus it has remained a less preferred alternative to the monopolar technique.
Laser surgery, which uses a light beam to cut away damaged tissue, is still used by a significant number of gynecologic surgeons, especially those who have performed more than 500 laparoscopic procedures. Ibis may be because initial laparoscopic procedures were performed via laser.
Laser surgery, however, generally is more expensive than monopolar electrosurgery and-does not coagulate blood as well. Lasers can be used with some degree of success in spray or topical coagulation, but they are ineffective for hemostasis over a large area. As for the harmonic scalpel, it is ineffective for either superficial or deep coagulation.
