ABSTRACT

Objective To study the feasibility of the ultrasonic scalpel in the management of cystic blood vessels during laparoscopic cholecystectomy(LC). Methods Abdominal blood vessels of two dogs were managed by ultrasonic scalpel under the conditions of two step output power,low tension,low holding force and blunt scalpel head.The blood vessels were sealed and arteries and veins of (1～11)mm were cut.On this basis,the technique was applied to the management of cystic vessels during laparoscopic cystic and biliary operation. Results The sealing and cutting effect was good for the blood vessels of less than 9mm 140/150(93 3%).No blood oozing was found at the cutting ends of blood vessels during and after operation.In all 706 cases of laparoscopic gallbladder and biliary duct operations,no bleeding was found at the cutting ends of blood vessels during and after operation. Conclusions Ultrasonic scalpel can be directly used to seal and cut cystic artery during laparoscopic cholecystectomy.
