Liver Resection with the Nd: YAG Laser: A Comparison of a New Contact Probe, the Laser Scalpel, with the Conventional Non-Contact Method
The technique of liver resection is well standardized, but recent reports still show that major liver resection is associated with an operative mortality of 4–20%. We recently compared the Nd:YAG laser and the Cavitron ultrasonic surgical aspirator (CUSA) with the routine blunt dissection method of performing a liver resection (1). The non-contact Nd:YAG laser resulted in a significant reduction in operating time compared to the other two methods (p<0.01), decreased the perioperative blood loss, but caused more extensive tissue necrosis. The study compares the conventional non-contact with the new contact artificial sapphire designed as a laser scalpel (2) in performing a liver resection with the Nd:YAG laser. Assessment included technical feasibility, duration of resection, tissue changes, adhesions, smoke production and blood loss.
