Objective To systematically evaluate the efficiency of laparoscopic hepatectomy(LH) and conventional
open hepatectomy (OH)in patients with hepatocellular carcinoma (HCC).
Methods The literatures about the therap-eutic effect of LH and OH on hepatocellular carcinoma were collected from PubMed, Chinese Journal Full-text Database (CJFD), Wanfang Database, China Doctor/Master Dissertations Full-text Database (CDMD), and China Proceedings of Conference Full-text Database (CPCD)from 2000 to 2011. RevMan 5.0 software was used for data analysis.
Results Eleven controlled clinical trials were included in this analysis. These studies included a total of 781 patients:325 treated with LH and 456 treated with OH. The results of meta-analysis showed that LH group had shorter operation time
〔WMD=-20.85, 95% CI (-29.54, -12.16), P<0.000 01〕, less operative blood loss 〔SMD=-0.42,95% CI
(-0.65,-0.19), P=0.000 4〕, a lower postoperative morbidity rate 〔OR=0.43,95% CI (0.28,0.65),P<0.000 1〕, and shorter hospitalization days 〔WMD=-4.32,95% CI (-6.29,-2.34),P<0.000 1〕 than OH group. There was no significant difference in postoperative recurrence (P=0.80), overall survival in 1-year (P=0.98), 3-year (P=0.41), and 5-year (P=0.12), and in disease-free survival in 1-year (P=0.15), 3-year (P=0.62), and 5-year (P=0.99)between the two groups.
Conclusions For the patients with hepatocellular carcinoma localized to the CouinaudⅡ,Ⅲ,Ⅳ,Ⅴ,and Ⅵ segments with a maximum lesion size of 5cm, as well as the tumor has no effect on the exposure of blood vessel of the first and second hepatic portal, and the liver functions are classified as Child B or A high grade, the laparoscopic liver resection is priority considered in the conditions allow.
