Risk factor analysis of postoperative complications in colorectal cancer patients / 西安交通大学学报(医学版)

ABSTRACT

Objective To investigate the risk factors of complication rate after colorectal cancer operation.Methods This study recruited a total of 254 non-emergency colorectal cancer patients admitted to our hospital between December 2005 and December 2006,and then evaluated the effects of life style,preoperative factors and intraoperative factors on postoperative complications.Results Single factor analysis showed that the postoperative complication rate was not significantly affected by gender,age,obesity,palliative/curative resection,anesthesia style as well as preoperative drinking or smoking history.Preoperative complications(P=0.001),tumor stage and operation time(P=0.025) affected the postoperative complicatin rate.Multi-factor logistic regression analysis showed that preoperative complications were the only risk factor of postoperative complications [P=0.001,OR=5.871,(95% CI 2.958-11.651)].Conclusion Old age as such does not represent a contraindication for surgical treatment.Preoperative complications,operation time and tumor stage significantly affect the postoperative complication rate.Preoperative complications are the strongest risk factor of all.Therefore,reasonable perioperative managements and shortening operation time are the key to reducing postoperative complications.
