Core Tip	Laparoscopic microwave ablation is safe and effective for small hemangiomas as it does not block the first hepatic portal. Giant hemangiomas (diameter ≥ 10.0 cm) are more commonly treated with hepatic resection rather than microwave ablation. If the first hepatic portal is not blocked, surgery is simpler and quicker for large hemangiomas (5.0 cm ≤ diameter < 10.0 cm). Conversely, blocking the first hepatic portal reduces the “heat sink effect” - a phenomenon where blood flow dissipates heat during ablation, thereby improving ablation efficiency and lowering the incidence of adverse reactions. However, there is no consensus or research on whether to block the first hepatic portal in this case.
