The present report describes a novel approach to and presents the surgical results for laparoscopic hepatectomy of the left lobes in small dogs. A purely laparoscopic four-port approach was used in seven beagles. The left triangular ligament was cut first, then the base of the left medial lobe (LMB) was ligated with silk thread using a needle, and the liver parenchyma of the LMB approximately 0.5 cm above the ligation site was removed with LigaSure. The left lateral lobe (LLB) was removed in the same manner. Blood was collected on postoperative days 1, 3, 7, and 14 for laboratory testing. Left hepatic lobe resection was successfully completed in all dogs, with an average operation time of 102.53 ± 9.07 min and an average blood loss of 32.10 ± 6.43 ml. Serious postoperative complications were not observed. The white blood cell (WBC) count and alkaline phosphatase (ALP) level were significantly increased in experimental dogs 1 day after surgery (P < 0.05); aspartate transferase (AST) and alanine transaminase (ALT) were significantly different before and after surgery (P < 0.01); and all the indicators were basically normal seven days after the operation. Exploratory laparoscopy at 28 days revealed adhesion of the surface of the liver section to the omentum or the gastric wall, but there were no other abnormal findings. The combined application of liver pedicle ligation and LigaSure for liver lobectomy provides a simple and effective method for generating liver lobectomy models for research on liver disease and regeneration and a feasible laparoscopic liver lobectomy operation scheme for small dogs (10–15 kg).
