Abstract：【Objective】 To investigate the efficacy and technical aspects of laparoscopic ultrasound-assisted microwave ablation in the treatment of hepatic hemangioma. 【Methods】 The clinical data of 9 patients with hepatic hemangioma larger than 5 cm in diameter undergoing laparoscopic ultrasound-assisted microwave ablation from March 2018 to October 2019 were retrospectively analyzed. 【Results】 Laparoscopic ultrasound-assisted microwave ablations were performed successfully in all the 9 patients without any open conversion. The average operation time was (189±58) min, average ablation time was (21±4.8) min, average blood loss was (138±245) mL, and the average length of postoperative hospital stay was (7.8±1.4) d. The main complications included hemoglobinuria in 4 cases (44.44%), fever in 4 cases (44.44%), and intrahepatic biloma in one case (11.11%), but no serious complications such as pneumothorax, postoperative hemorrhage, skin burned and adjacent organ injuries occurred. Postoperative follow-up was conducted for 6 to 12 months. There were 8 cases (88.89%) with complete elimination of lesions, and 1 case (11.11%) with lesion reduction more than 75%.【Conclusion】 Laparoscopic ultrasound-assisted microwave ablation is safe and effective in treatment of hepatic hemangioma, and it is recommended to be used in clinical practice.
