Abstract
Objective To evaluate the radical effect and prognosis of laparoscopic resection for colorectal cancer in China.Methods Articles of non.randomized comparative studies(NRCs)of laparoscopic resection and open Burgery for colorectal cancer which were published before October 2007 were retrieved,and correlated indexeswere extraeted for meta.analysis.Results The mean quality score of the 14 articles selected was 18.92±1.27.The basic characteristics of patients in laparoscopic resection group were similar to those in open surgery group.Compared with open surgery group,the incised length of the intestine in the laparoscopic resection group was shorter by 0.66 cm.and the distance between distal margin of resection and tumor was farther by 0.26 cm.The 2-year survival rate of patients in laparoscopic group Was 1.67 times higher than that of open surgery group.There was no significant difference upon follow-up rate,tumor diameter,number of resected lymph nodes,local recurrence rate and distal metastasis rate between the 2 groups.Conclusions The results of meta-analysis show that laparoscopic resection has the sanle radical effect as open surgery for colorectal cancer.but the 2-year survival rate of patients treated by laparoscopic resection is comparatively higher.
