Abstract:
Objective To study the local recurrence,distant recurrence and survival rate of anastomotic leak after surgery in patients with colorectal cancer.Methods Chinese and English related studies published from January 1970 to June 2011 were searched in PubMed/Medline,Excerpta medica database (EMBASE),Springger,Google scholar,China national knowledge infrastructure (CNKI),China biomedical literature database (CBM),Wanfang data.All controlled trials related to anastomotic leak after surgery in patients with colorectal cancer were retrieved.Outcomes were evaluated including local recurrence,distant recurrence and survival rate,then Mate-analysis was performed using RevMan 5.0 software provided by the Cochrane network.Results Fifteen studies were included,including a total of 18 225 patients.There were 1 425 patients with anastomotic leak and 16 800 patients without anastomotic leak.The patients with anastomotic leak were compared with patients without anastomotic leak.The OR value of local recurrence was 2.47 (95％ CI 1.72-3.55,P ＜ 0.01),the OR value of distant recurrence was 1.18 (95％ CI 0.98-1.43,P =0.08),and the OR value of 5-year survival rate was 1.68 (95％ CI 1.36-2.07,P ＜ 0.01).Conclusions Anastomotic leak after surgery is a bad prognosis factor in patients with colorectal cancer.It can increase the local recurrence rate,and decrease survival rate.
