Objective To explore the effect of radio frequency ablation (RFA) combined with transcatherterarterial chemo embolization (TACE) and percutaneous puncture hydrochloric acid injection(PHI) for hepatic tumors unable to resection. Methods The clinical data of 40 cases of patients with unable resection liver cancer (URLC) treated by RFA combined with TACE and PEI were analyzed retrospectively.Results There were 30 cases of primary hepatic tumor(PHT) and 10 cases of metastasis hepatic tumor(MPT) , in this series. Examination of ultrasound, CT and MRI showed the tumors shrink or steady in 39 patients.Among 30 patients with damage by ethanol, 18 cases were AFP positive before treatment and 16 cases of them AFP decreased to normal level after operation. No severe complication was seen in the series. Conclusion RFA combined with TACE and PEI is a safe, well tolerable and effective method for hepatic cancer, and may improve the treatment efficacy of URLC.

Objective To study the effects of laparoscopic and open hepatectomy(LH and OH) on liver function of patients,and to evaluate patients′ traumatic reaction after LH.Methods Forty patients scheduled to undergo hepatectomy were divided into LH group and OH group randomly in PLA General Hospital from Jun.2004 to Feb.2005.Data of pre-and post-operative liver function of the two groups were compared.Results Postoperative mean value of ALT,AST and LDH in LH group and OH group elevated quickly,and the postoperative mean value of these markers was significantly different compared to that of the preoperative value,and the mean value in OH was higher than that in LH.There was no significant difference between postoperative and preoperative level of ALP and ?-GT in both groups,but postoperative mean value of them in OH was higher than that in LH.There was no significant difference between the 2 groups in TBIL and DBIL level,but their postoperative mean value in OH was higher than that preoperatively.Conclusions The effects of LH on liver function in patients are less than those of OH.This finding suggests that patients′ traumatic reaction after LH is less than that after OH and this is beneficial for the reduction of hepatic failure after LH.
