Abstract    Objective    To summarize the clinical experience of radiofrequency ablation combined with devascularization in treating primary liver cancer with portal hypertension. Methods    The clinical data of 69 cases of primary liver cancer with portal hypertension treated with radiofrequency ablation combined with devascularization from June 2004 to June 2012 in Department of Hepatobiliary Surgery, Beijing Ditan Hospital of Capital Medical University (the study group) were analyzed retrospectively. At the same time, the clinical data of 83 cases treated with the partial hepatectomy combined with devascularization (the control group) were compared with the data of the study group. Postoperative liver function grade, complications, the hemorrhage recurrence rate of gastroesophageal varices, postoperative overall survival and postoperative tumor-free survival of two groups were observed. Results    There was no dead case in two groups. In the study group, liver dysfunction was mainly mild or moderate degree, and the extent of liver function damage was significantly lower than the control group (P<0.05). Postoperative complication incidence in study group was lower than that in the control group (P<0.05). Two groups had no difference in postoperative  1-, 3-, and 5-year overall survival rate, tumor-free survival rate and gastroesophageal varices hemorrhage recurrence rate. Conclusion    Under the conditions of suitable selection of indications, radiofrequency ablation combined with devascularization can get less liver function damage and postoperative complications with similar long-term survival rate compared with partial hepatectomy combined with devascularization.
