| Abstract |
PURPOSE
Despite increased effort for the detection of early colorectal cancer, advanced disease presenting as obstruction or perforation still accounts for 8 to 29% and 3-8% of all colorectal cancers, respectively. The aim of this retrospective study was to evaluate the clinical characteristics, the surgical methods, the complications, and the risk factors of obstructive or perforated colorectal cancer that may influence the outcome.
METHODS
A retrospective study was carried out in 60 patients with colorectal cancer, who underwent surgery due to obstruction or perforation from March 2000 to December 2005. The colorectal cancers were considered to be complicated when clinical signs of peritonitis were observed, the radiologic characteristics of the tumor did not permit preoperative mechanical bowel preparation, or perforation existed, when these observations were confirmed by operative findings. The following data were analyzed: clinical characteristics, surgical methods, complications, and risk factors.
RESULTS
Thirty-three patients (55%) had obstruction, and 27 patients (45%) had perforation. Overall, major complications occurred in 33.3% and 48.5%, respectively. The mortality rates were 6.1% and 14.8%, respectively. Risk factors for major complication were age, perforation, and transfusion whereas those for mortality were perforation and American Society of Anesthesiologists (ASA) class.
CONCLUSION
The risk factors of complication were old age, transfusion, and perforation and those for mortality was perforation and ASA class. Earlier diagnosis and prompt, intensive, careful management should be attempted in these high-risk patients. |
