Laparoscopic Liver Resection and Enucleation of Liver Hemangioma with Selective Hepatic Vascular Occlusion: Technique and Indications.

BACKGROUND: Liver resection or enucleation has been the basic treatment for liver hemangioma. However, there were few reports about laparoscopic surgery (LS) of hemangioma. The intention of this study is to explore the indication and efficacy of LS for laparoscopic hepatectomy (LH) and develop an opinion of these modern developments.

PATIENTS AND METHODS: Forty-four patients with LH underwent LS, with hemihepatic vascular occlusion (HVO group n = 24) or modified vascular occlusion (MVO group n = 20), and were retrospectively reviewed, including patients' demography, surgical technique, tumor size and location, blood loss, operation time, complications, modes of hepatic vascular occlusion and changes in postoperative liver function, and the difference in patients demography and operative outcome between HVO and MVO groups were compared as well.

RESULTS: There were no deaths. The mean operating time was 162 minutes, intraoperative blood loss was 335 mL, blood transfusion rate was 9.1%, postoperative complication rate was 18.2%, and length of hospital stay was 7.3 days. Although the tumor size in the HVO group was significantly larger than that in the MVO group, there were no differences concerning operating outcomes, length of stay, and postoperative serum alanine transaminase (ALT), aspertate aminotransferase (AST) level between the HVO and MVO groups.

CONCLUSIONS: LS was feasible for LH with hepatic vascular occlusion with zero mortality and low complication rate.
