Abstract
Laparoscopic surgery demands flexibility in that it requires selection of the method most suited to the patient, technician, and circumstances. The instruments used are also an important factor in determining the safety and ease with which laparoscopic surgery is conducted. Here we introduce procedures for the enucleation of uterine myoma and the laparoscopic, techniques we use, and compare the electric scalpel, laser scalpel, and ultrasound scalpel (harmonic scalpel). While the laser scalpel is an important tool in laparoscopic surgery, we did not find it to have any clear advantages over the electric scalpel. As for the harmonic scalpel, although it transiently produces a smoke-like vapor, the field of vision remains clear. The harmonic scalpel was equal to the laser scalpel in terms of incision and coagulation ability, and is expected to become an important tool in the futere.
Ultimately, the advisability of surgery and the type of operations that are possible will depend not only on the instruments used, but also on the views of the surgeon regarding a particular procedure and the surgen's level of technical skill.
