PURPOSE
The aim of the present communication was to describe an accessory hepatic lobe in two patients and to outline the significance of the timely identification of this very rare anatomic variation for the clinical practice.
METHODS
In the course of right hemihepatectomy, accessory liver lobes were detected in two patients. Their diagnosis was confirmed by histopathology and cholangiography.
RESULTS
Both accessory hepatic lobes arose from the left liver segments. The first lobe was detected in a 56-year-old male operated on for a retroperitoneal liposarcoma. It amounted to 15% of the standard liver volume and was attached to liver segments 2 and 3 by a stalk. The second accessory lobe was found out in 45-year-old female operated on for a colon cancer and synchronous liver metastases. It was less than 15 g in weight and attached to the main liver by a mesentery as its bile duct drained into an extrahepatic duct.
CONCLUSIONS
The accessory hepatic lobes require timely diagnosis. They should be kept in mind in cases with acute surgical abdomen.
目的
本报告旨在描述两例患者的副肝叶，并概述及时识别这种极为罕见的解剖变异对临床实践的意义。
方法
在右半肝切除术中，两名患者被检测出副肝叶。通过组织病理学和胆管造影术确诊。
结果
两个副肝叶均起源于左肝段。第一个副肝叶在一名因腹膜后脂肪肉瘤接受手术的56岁男性患者中被发现。其体积占标准肝脏体积的15%，通过一个蒂附着于肝段2和3。第二个副肝叶在一名因结肠癌伴同步肝转移接受手术的45岁女性患者中被发现。其重量小于15克，通过肠系膜附着于主肝，其胆管汇入肝外胆管。
结论
副肝叶需要及时诊断。在急性腹痛病例中应予以考虑。
