We studied intraperitoneal bleeding in laparoscopic bipolar radiofrequency ablation (RFA) for hepatocellular carcinoma and feasibility of needle tract cauterization (NTC), retrospectively. Patients treated with laparoscopic RFA divided into three groups: (1) using monopolar RFA, (2) using bipolar RFA before and (3) after modification of NTC method. Age, gender, platelet count, prothrombin time and Child-Pugh score were equal in each group. Though NTC was performed in all procedures, bleeding from needle tract was observed in 7/41 (17.1%) in monopolar group, 20/39 (51.3%) in bipolar group and 10/49 (20.4%) in bipolar with modified NTC group (
P<0.002). Careful attention and appropriate treatment to intraperitoneal bleeding are required in bipolar RFA using thick and plural applicators.
