When should surgery be performed for an HH? What size of HH should undergo surgical resection? These questions remain controversial, and no consensus has been reached to date. Foreign researchers define tumors >4 cm in diameter as giant hemangiomas. The idea is that a tumor >4 cm at the hepatic margin or hilum is easy to rupture or may compress the hilar bile duct and blood vessels, for which surgical treatment is preferred [2]. Domestic scholars deem that surgical treatment is needed for tumors >10 cm with rapid growth over a short-term period, tumors >5 cm located at the margin of the left external lobe or the right hepatic lobe, or tumor masses with nearly half of the mass protruding out of the liver. Currently, our medical center adopts the following surgical indications for HHs:

The biological behavior of HHs is consistent with the manifestations of benign tumors. Therefore, there is no vascular invasion or intrahepatic and extrahepatic metastasis in clinical cases of HH. Depending on the growth location and tumor size of HH and the classification of the liver segments, the surgical options for HH presently include the following:
