To describe the management of extensive hepatectomy in 2 dogs.
A 10-year-old female intact mixed-breed dog (case 1) and an 11-year-old male castrated mixed-breed dog (case 2) were presented for surgical evaluation following diagnosis of a hepatic mass.
CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES: 16 months before presentation, case 1 had undergone a left lateral liver lobectomy, which resulted in an incomplete resection of hepatocellular carcinoma. Both dogs underwent surgical excision of the liver mass.
In case 1, surgery consisted of the removal of the remaining left medial lobe, as well as the central division. Case 2 received a complete left and central division hepatectomy. Histopathology confirmed a diagnosis of hepatocellular carcinoma in both dogs. Liver enzyme resolution and lack of tumor recurrence were confirmed with chemistry panel and abdominal ultrasonography in both dogs.
This case report describes, for the first time, the clinical management and outcome of extensive hepatectomy in 2 dogs. We propose that extensive hepatectomy, staged or synchronous, is possible in a clinical setting.
描述 2 只犬广泛肝切除术的管理。
一只 10 岁的雌性完整混血犬（病例 1）和一只 11 岁的雄性去势混血犬（病例 2），在诊断为肝肿块后接受手术评估。
临床症状、进展和程序：在出现症状前 16 个月，病例 1 接受了左外侧肝叶切除术，导致肝细胞癌不完全切除。两只狗都接受了肝肿块的手术切除。
在病例 1 中，手术包括切除剩余的左内侧叶和中央部。病例 2 接受了完整的左叶和中央部肝切除术。组织病理学在两只狗中均证实为肝细胞癌的诊断。在两只狗中，通过化学分析和腹部超声检查均确认了肝酶的恢复和无肿瘤复发。
本病例报告首次描述了 2 只犬广泛肝切除术的临床管理和结果。我们提出，广泛肝切除术，分期或同步进行，在临床环境中是可能的。
