Thermal Methods

This group includes different instruments that have in common the ability to seal blood vessels or to cut surfaces by protein denaturation induced by heat. Among these instruments are the laser, the monopolar electrical cautery (Bovie) and the bipolar cautery. In the living-donor hepatectomy, only the monopolar and bipolar cauteries are frequently used. A popular technique is to use either instrument to obtain coagulation of small vessel on the cut surface of the parenchyma that has been previously transected with other devices, i.e., the ultrasonic or the water-jet dissectors [29].
