Laser surgery in exsanguinating liver injury.

Abstract:

:Thirty-two conditioned 15-18 kg dogs underwent laparotomy, heparinization, left lateral hepatic lobe injury and subsequent partial left lateral hepatic lobectomy. The hemostatic capabilities of the surgical scalpel combined with suture ligatures and stay sutures, the Bovie, and the CO2 laser were compared. The CO2 laser proved significantly more effective in achieving hemostasis both in comparison to the Bovine and the surgical scalpel combined with classical methods. The postoperative mortality utilizing the Bovie was 11%, the scalpel 30% and the laser 23%. Two of the three laser deaths were related to a bulky laser delivery system which can be redesigned. Postoperative laboratory evaluation revealed that SGOT, LDH, alkaline phosphatase, total protein, albumin and hemoglobin levels were altered in the postoperative period but returned to normal levels in uniform fashion in all groups. There was no statistical difference between various surgical modalities with regard to these parameters. The white blood count was significantly lower in laser dogs when compared to the other two groups. Other laboratory parameters were unchanged. Damage to liver tissue may be less extensive when the laser is utilized as opposed to the Bovie or stay suture methods of hemostasis and healing is equally good. The CO-2 laser is considered a valuable ancillary tool in hepatic resection and clinical evaluation is warranted.
