At present, the application of extended radical surgery in hilar cholangiocarcinoma (hCCA) remained controversial. The author reviewed the relevant literatures published in recent years and combined with his own experience, preliminarily discussed the application value of extended radical surgery in hCCA, and believed that: for some strictly selected cases of hCCA, under the premise of ensuring patient safety, extended radical surgery was an important treatment method for hCCA patients to obtain R0 removal, and the survival status of patients was better than that of palliative surgery, but the indications need to be strictly mastered. For patients with hCCA, whether to adopt extended radical surgery and the specific scope of surgical resection should be based on the scope of lesions and the involved organs, tissues and blood vessels to implement an individualized surgical program on the premise of comprehensive evaluation and full preparation before surgery. Do not blindly carry out extended radical surgery.
