Calot's triangle is an anatomical landmark of special value in cholecystectomy. First described by Jean-François Calot as an "isosceles" triangle in his doctoral thesis in 1891, this anatomical space requires careful dissection before the ligation and division of the cystic artery and cystic duct during cholecystectomy. The modern definition of the boundaries of Calot's triangle varies from Calot's original description, although the exact timing of this change is not entirely clear. The structures within Calot's triangle and their anatomical relationships can present the surgeon with difficulties, particularly when anatomical variations are encountered. Sound knowledge of the normal anatomy of the extrahepatic biliary tract and vasculature, as well as understanding of congenital variation, is thus essential in the prevention of iatrogenic injury. The authors describe the normal anatomy of Calot's triangle and common anatomical anomalies. The incidence of structural injury is discussed, and new techniques in surgery for enhancing the visualisation of Calot's triangle are reviewed. © .
Calot 三角是胆囊切除术中有特殊价值的解剖学标志。1891 年，Jean-François Calot 在他的博士论文中首次将其描述为一个“等腰”三角形，在胆囊切除术中，在结扎和分离胆囊动脉和胆囊管之前，需要仔细解剖这个解剖空间。尽管确切的时间尚不完全清楚，但 Calot 三角边界的现代定义与 Calot 的原始描述有所不同。Calot 三角内的结构及其解剖关系可能会给外科医生带来困难，特别是在遇到解剖变异时。因此，了解肝外胆道和血管的正常解剖结构以及对先天性变异的理解，对于预防医源性损伤至关重要。作者描述了 Calot 三角的正常解剖结构和常见的解剖异常。讨论了结构损伤的发生率，并回顾了增强 Calot 三角可视化的新手术技术。© 。
