Objective To explore the feasibility of high-frequency electric welding systemin cholecyste-ctomy when compared with ultrasound scalpel , Ligasure and traditional scalpel. Methods Ninety-six rabbits were enrolled in the study and divided into high-frequency electric welding system group , ultrasound scalpel group , Ligasure group and traditional scalpel group. The working temperature was recorded. Eight rabbits of each group were killed to observe the occlusion at 1st, 4th, 7th day postoperatively. Tissues were collected for observation under HE staining. Results High-frequency electric welding system group excelled in operative time , bleeding, working temperature, granulation tissue and inflammatory reaction. No significant difference was found in preope-rative and postoperative liver function test. Conclusion High-frequency electric welding system in cholecyste-ctomy has similar effect as ultrasound scalpel and Ligasure.
