Abstract
We have carried out a series of experimental laparoscopic cholecystectomy in dogs (n=5). In our animal experiments, laparoscopic removal of the gallbladder was performed by Nd-YAG laser, ligating the cystic artery and cystic duct with the clips used for vascular ligation. The irradiation of Nd-YAG laser for the ablation of the gallbladder using the non-contact type of quartz was done under 15 watts of output with 4, 000-5, 000 J in total energy. This procedure requires a comprehensive technical integration, such as the preparations of optimum instruments, excellent skills and the cooperation with surgeons. From the experience of these experiments, it will be concluded that this poocedure could be clinically applied in human patients.
