Hepatic lobectomy in the dog. A comparison of stapling and ligation techniques.

The left lateral hepatic lobe was removed in six dogs with a stapling instrument and in six dogs by blunt dissection and ligation. Both techniques were safe and effective. Lobectomy by dissection and ligation was slower and less complete than by stapling. Major intraoperative or postoperative hemorrhage did not occur with either method. Serum chemistry values were elevated after surgery in all dogs but did not differ significantly between treatment groups. Microscopic hemorrhage, necrosis, and inflammation of the lobectomy site were more pronounced after dissection and ligation than stapling.
