Laparoscopic-guided microwave ablation for exophytic hepatic haemangioma: A case series

BACKGROUND: Hepatic haemangioma (HH) is a common benign liver tumour and a potential risk factor for hepatic rupture and haemorrhage. There is currently no consensus on the optimal treatment approach. This study aims to evaluate the feasibility and safety of laparoscopic-guided microwave ablation (LMA) for exophytic HH. MATERIALS AND METHODS: A retrospective analysis was conducted on four patients admitted to our hospital from November 2023 to June 2024. The average age was 51 years (range: 39-61 years), and all patients were diagnosed with exophytic HH, with an average maximum diameter of 3.1 cm (range: 2.5-4.0 cm). RESULTS: Complete necrosis and shrinkage of the haemangiomas were achieved in all cases. The average operative time was 22.5 min, with blood loss ranging from 5 to 15 mL. No complications were observed, and the average hospital stay was 2-3 days. CONCLUSION: Based on our observations, LMA for exophytic HH is a safe and effective technique.
