摘要

在开放和腹腔镜手术中进行肝切除术需要精确的肝脏解剖学临床知识。副肝叶(ALL)是涉及肝脏多余叶的解剖学变异。尽管其起源尚不完全清楚,但对导致ALL的胚胎学过程的假设包括胚胎发育或形成过程中由于创伤或手术引起的腹内张力增加而导致的增生异常。在大多数情况下,副叶位于肝脏下方。Riedel 's lobe是最著名的副叶,对应于肝脏V节和VI节的肥大。在本报告中,我们报告了一位老年女性尸体的病例,她表现出非典型的ALL左侧变异,通过副韧带附着。因此,我们讨论大体形态学、组织病理学、临床和手术意义,以改善未来患者的预后。

A Comprehensive View into a Novel, Accessory Liver Lobe
Precise clinical knowledge of liver anatomy is required to perform a hepatectomy, in both open and laparoscopic surgery. Accessory liver lobes (ALL) are anatomical variations involving supernumerary lobes in the liver. Although their origin is not entirely understood, hypotheses for the embryological processes resulting in an ALL include hyperplastic anomaly during embryological development or formation because of increased intraabdominal tension from trauma or surgery. In most cases, the accessory lobe is located inferior to the liver. Riedel’s lobe is the best-known example of an accessory lobe, corresponding to hypertrophy of liver segments V and VI. In this report, we presented the case of an elderly female cadaver who showed an atypical ALL left variant attached through an accessory ligament. Therefore, we discuss the gross morphology, histopathology, and clinical and surgical implications to improve future patient outcomes.
