Laser or electrocautery for laparoscopic cholecystectomy?

摘要: There are few concerns related to laparoscopic cholecystectomy that evoke as much emotion the question of which is superior energy source, laser or electrocautery. Monopolar radio frequency electricity (electrosurgery) and collimated coherent light (laser) injure tissue by generation heat, in this regard remarkably similar. The greatest differences between these sources heat predictability injury, selective absorption free beam energy, ability coagulate, cost. Although there no prospective data yet available answer superiority, it appears electrosurgical dissection may be faster generally less costly. Laser more precise. In difficult cases, hemostasis with electrosurgery.
