Long-term Survival and Safety of Laparoscopy and Open Surgery for Colorectal Cancer:Meta-analysis / 中国微创外科杂志

ABSTRACT

Objective To compare the long-term survival rate and safety of laparoscopic surgery(LS)with those of open surgery(OS)in the treatment of colorectal cancer by using Meta-analysis.Methods Randomized controlled trails reported between January 1991 and July 2007 comparing the outcomes of LS and OS in patients with colorectal cancer were collected and analyzed by using RevMan4.2.Results Totally,14 reports involving 4989 colorectal cancer patients were enrolled in this study.Significant difference was found in the morbidity rate of bowel adhesion between the two groups(P=0.002).The long-term outcomes,including the 3-and 5-year survival rates,and the rates of local recurrence and distant metastasis,were not significantly different between the two groups.Conclusions Laparoscopic surgery is effective and safe for colorectal cancer with a similar long-term survival rate as that of the open surgery.
