INTRODUCTION
Ectopic liver tissue is a rare entity, reported to occur in several intra-, retro- and extra- peritoneal sites, including the gallbladder. It is usually detected incidentally, during laparoscopy, laparotomy, or autopsy. Several possible mechanisms may explain the development of liver ectopia. Although ectopic liver tissue is usually asymptomatic, it behaves like orthotopic liver, developing the same pathologic conditions.
CASE PRESENTATION
We describe the case of a 54-year-old woman who was found to have a nodule attached to the gallbladder wall without any connection with the main liver, during an elective laparoscopic cholecystectomy for gallstone disease. The nodule was removed with the gallbladder and identified histologically as normal ectopic liver tissue.
CONCLUSION
It would seem sensible to resect the ectopic tissue if encountered during cholecystectomy for gallstones. Laparoscopic management of ectopic liver can be feasible.
引言
异位肝组织是一种罕见的情况，据报道可发生于多个腹腔内、腹膜后及腹膜外部位，包括胆囊。它通常在腹腔镜检查、剖腹手术或尸检时偶然被发现。有几种可能的机制可以解释肝异位的发生。尽管异位肝组织通常无症状，但它的表现与原位肝相似，会发生相同的病理状况。
病例报告
我们描述了一名54岁女性的病例，该患者在因胆结石疾病接受择期腹腔镜胆囊切除术时，发现胆囊壁上附着一个与主肝无任何连接的结节。该结节与胆囊一并切除，经组织学鉴定为正常异位肝组织。
结论
在因胆结石进行胆囊切除术时，如果遇到异位组织，将其切除似乎是合理的。腹腔镜处理异位肝可能是可行的。
