Core Tip
Core Tip: Laparoscopic microwave ablation (LMWA) patients have less surgical bleeding and recover faster. Symptom improvement rates are similar between the LMWA and large hepatic hemangiomas resection groups, with no significant difference. The LMWA group has a lower rate of postoperative complications. Transient liver function changes after LMWA usually resolve within a week. Transient liver function changes may result from heat damage and tissue thermal coagulation.
