Background Surgical indications for liver hemangioma remain unclear. Methods Of 510 patients undergoing surgical resection for liver hemangioma in 118 Japanese centers between 1998 and 2012, abdominal symptoms, diagnostic accuracy, and surgical outcomes were analyzed to propose size-based surgical indications. Patients were classified into four groups based on tumor size: Group A ≤5 cm ( n = 122, 24%), Group B 5-10 cm ( n = 164, 32%), Group C 10-15 cm ( n = 124, 24%), and Group D >15 cm ( n = 100, 20%). Results Hemangiomas in Group A were most frequently diagnosed as malignant tumors (43.5%) due to the absence of typical imaging findings and with highest incidence of positive HBV (15.7%). Diagnostic accuracy was 98.4% in Groups B to D. Liver failure after hepatectomy was higher in Group D than in Groups A to C (3.0% vs. 0.5%, P = 0.02). Only one operative death was observed (0.2%) in Group D. Conclusions In patients with ≤5 cm hemangioma, surgical resection can be indicated when a malignant tumor cannot be ruled out. However, surgery for 5-10 cm asymptomatic hemangiomas should be limited. Experienced hepatic surgeons should conduct hepatectomy for tumors >15 cm to avoid serious morbidity or mortality.
