Safety and effective of laparoscopic microwave ablation for giant hepatic hemangioma: A retrospective cohort study

INTRODUCTION: The purpose of this study was to evaluate the advantages and disadvantages of laparoscopic microwave ablation (LMWA) as compared with conventional open resection (ORES) for the treatment of giant hepatic hemangioma. METHODS: and analysis: A retrospective chart review was conduct on patients with hepatic hemangioma underwent LMWA or ORES between 2014 and 2016. RESULTS: Of 131 patients, 37 patients underwent ORES and 94 patients underwent LMWA. Blood loss, operative time, postoperative hospital stay, hospital cost (RMB) were significantly different between two groups. Patients after LMWA experienced significantly less pain than those patients undergoing ORES. At a mean follow-up period of 12.8 ± 3.6 months in ORES group and 13.5 ± 2.5 months in LMWA group, no long-term complication was observed. CONCLUSION: Compared with ORES, LMWA is a safe and effective minimally invasive for treating giant hepatic hemangioma.
