肝尾状叶切除是治疗尾状叶恶性肿瘤的首要手段。由于尾状叶位于肝脏深面，显露困难，周围重要血管结构较多，因此曾被认为是外科手术的禁区。随着肝脏外科技术的不断发展，尾状叶手术也得到了长足进步。根据肿瘤的位置、大小和肝脏的质地选择合理的手术入路，术中熟练处理和保护周围重要的血管结构是尾状叶手术主要的技术原则和难点。而肿瘤外科无瘤技术原则在手术中也仍然不能忽视。

With the continuous development of surgical techniques, caudate lobectomy has also been improved considerably. The major technical principles and difficulties include a rational surgical approach according to the location and size of the tumor and texture of the liver, skilled management and protection of the major vascular structure around. The no-tumor procedure and non-touch technique also play a vital role in caudate lobe resection.
