Data on signalment, blood tests, imaging, intraoperative findings, histopathology, and clinical outcomes were collected.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Masses were located in the right lateral, right medial, left medial, and left lateral lobes, or the caudate process of the caudate lobe. All dogs completed laparoscopic hepatectomy without conversion to laparotomy. Median operation time was 165\u2009min (range: 90\u2013230\u2009min). Histopathology revealed hepatocellular carcinoma (\n n<\/jats:italic>\n \u2009=\u20099) and adenoma (\n n<\/jats:italic>\n \u2009=\u20091) and nodular hyperplasia (\n n<\/jats:italic>\n \u2009=\u20092). Median hospital stay was 3\u2009days (range: 2\u20134\u2009days). One dog developed tension pneumothorax from an iatrogenic diaphragmatic injury, and three were diagnosed with bradycardia and hypotension following the Pringle maneuver. Disseminated hepatocellular carcinoma lesions were detected on the greater omentum in one dog 724\u2009days post\u2010surgery. All dogs were discharged.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Laparoscopic hepatectomy using EHPC was safely performed in dogs with liver masses, with favorable short\u2010 and long\u2010term outcomes.<\/jats:p>\n <\/jats:sec>\n \n Clinical relevance<\/jats:title>\n Laparoscopic hepatectomy using EHPC is a viable option for dogs with liver masses, provided there is no
