Safety evaluation of laparoscopic colorectal surgery in elderly patients / 中华消化外科杂志

ABSTRACT

Objective To evaluate the safety and feasibility of laparoscopie colorectal surgery in elderly patients.Methods The clinical data of 117 patients with colorechal cancer who had been admitted to People's Hospital of Peking University from January 2005 to December 2008 were analyzed retrospectively.Ail patients were divided into laparoscopic group(n=49)and open group(n=68).The postoperative conditions,incidence of complications and results of follow-up of patients in the 2 groups were compared.All data were analyzed via t test,chi-square test and Mann-Whitney U test,and the survival was analyzed via Kaplan-Meier method and Log-rank test.Results The mean operation time in laparoscopic group was(246±64)minutes,which was significantly longer than(218±50)minutes in open group(t=-2.677,P<0.05).The volume of blood loss,anal exsufflation time,postoperative hospital stay,ratio of patients who used analgesics and incidence of complications were (207±135)ml,3 days,12 days,45%(22/49)and 20%(10/49)in laparoscopic group,and were(296±178)ml,4 days,14 days,74%(50/68)and 44%(30/68)in open group,with significant difference between the 2 groups(t=2.920,U=770.5,1181.0,X~2=9.864,7.115,P<0.05).The length of bowel resected and number of lymph node dissected were(19±7)cm and 13±6 in laparoscopic group,and were(20±8)cm and 16±6 in open group,with no significant difference between the 2 groups(X~2=0.790,t=2.007,P>0.05).The 1-and 3-year accumulative survival were 95.4%and 85.2%in laparoscopic group,and were 94.7%and 82.3%in open group,with no significant difference between the 2 groups(X~2=0.581,P>0.05).Conclusion Laparoscopic surgery is safe and feasible for elderly patients with colorectal cancer.
