| 1 | Five-year long-term outcomes of laparoscopic surgery for colon cancer显示文摘AIM:To perform a meta-analysis to answer whether long-term recurrence rates after laparoscopic-assisted surgery are comparable to those reported after open surgery.METHODS:A comprehensive literature search of the MEDLINE database,EMBASE database,and the Cochrane Central Register of Controlled Trials for the years 1991-2010 was performed.Prospective randomized clinical trials(RCTs)were eligible if they included patients with colon cancer treated by laparoscopic surgery vs open surgery and followed for more than five years.RESULTS:Three studies involving 2147 patients reported long-term outcomes based on five-year data and were included in the analysis.The overall mortality was similar in the two groups(24.9%,268/1075 in the laparoscopic group and 26.4%,283/1072 in open group).No significant differences between laparoscopic and open surgery were found in overall mortality during the follow-up period of these studies[OR(fixed) 0.92,95%confidence intervals(95%CI):0.76-1.12,P=0.41].No significant difference in the development of overall recurrence was found in colon cancer patients,when comparing laparoscopic and open surgery [2147 pts,19.3%vs 20.0%;OR(fixed)0.96,95% CI:0.78-1.19,P=0.71].CONCLUSION:This meta-analysis suggests that laparoscopic surgery was as efficacious and safe as open surgery for colon cancer,based on the five-year data of these included RCTs. | Bai HL Chen B Zhou Y Wu XT. | 2010 | World Journal of Gastroenterology2010，16，39： | 13 |
