Tóm tắt

Electrocautery-induced thermal injury contributes to morbidity and mortality after laparoscopic surgery. Ultrasonic dissection is an alternative technique that may produce less thermal injury. We compared the amount of acute thermal injury caused to jejunal free flaps isolated with laparoscopic electrosurgical instruments with that caused by ultrasonic dissection (laparoscopic coagulating shears). Canine jejunal free flaps were isolated by electrocautery or laparosonic coagulating shears and remained viable on a vascular pedicle. After a period of ischemia and reperfusion, the flaps were resected to simulate harvesting and reimplantation. Thermal injury was observed at the site of dissection and was graded histologically. At the margin of the jejunal free flaps, the laparosonic coagulating shears produced less thermal injury (score, 2.2 at level 3) than the electrocautery grasping forceps (score, 3.7 at 35 W and 4.1 at 70 W). The laparosconic coagulating shears produced less thermal injury to a jejunal free flap than did electrocautery. Ultrasonic dissection is an alternative to the complications produced by electrocautery during laparoscopic dissection.
