Nd:YAG激光刀兔肝叶切除实验及电子显微镜的观察

Pantial liver lobe resection with a CW Nd-YAG laser as light scalpel were carried out in ten adult rabbits,which showed the usefulness of the focused Nd-YAG laser beam in liver surgery. The output power of the laser was 15～20 watts.Measurement of SGPT and blood routine were made preoperatively and postoperatively.The cut edge was bloodless with a 1～3 mm layer of carbonization and coagulation at the surrouding tissure.24 hrs after operation,SGPT increased to more than 130 units,and blood hemoglob
