The accessory liver lobe (ALL) of the gallbladder wall is rare, mentioned by Meckel since 1822. We present two cases of ALL occurring in two adult women. The ALLs were diagnosed at microscopic examination of cholecystectomy specimens for lithiasic cholecystitis and were located at the gallbladder body level. They measured 0.5 and 1.1 cm and were pediculated from the gallbladder serosa. Luschka duct complexes were seen in the adjacent subserosa in one of the cases. The main clinical relevance of ALL of the gallbladder resides in the differential diagnosis with a lymph node and in the risk of peroperative hemorragia or bile leakage by sectioning of the connecting blood vessels and/or bile duct. Intraparietal ALL may interfere with dysmotility, possibly resulting in bile stagnation and stone formation.
胆囊壁副肝叶（ALL）较为罕见，自1822年起被梅克尔提及。我们报告两例发生在成年女性的ALL病例。这些ALL在因结石性胆囊炎行胆囊切除术标本的显微镜检查中被诊断出来，位于胆囊体部水平。它们大小分别为0.5厘米和1.1厘米，从胆囊浆膜带蒂。其中一例在相邻浆膜下层可见卢施卡管复合体。胆囊ALL的主要临床意义在于与淋巴结进行鉴别诊断，以及在手术中切断连接血管和/或胆管时存在术中出血或胆汁漏的风险。壁内ALL可能会干扰运动功能，可能导致胆汁淤积和结石形成。
