AIM: The purpose of our study was to estimate the incidence of SSI (Surgical site infection) and the effect of COLA
(contamination, obesity, laparotomy and ASA grade) score on SSI in patients undergoing rectal surgical procedures for
MATER AL OF STUDY: A total of 92 patients who underwent operation for rectum cancer were enrolled in this study.
Wound surveillance was performed in all patients by a staff surgeon identified infected wounds during the hospital stay,
and collected information for up to 30 days after operation.
RESULTS: The overall rate of incisional SSI and organ/space SSI was 22.8% and 7.6% respectively. Surgical site infection
rates were 14.2%, 20.58%, 40.7%, 57.1% for COLA 1,2,3 and 4 scores respectively. The area under the receiver/
operator characteristic curve for the score was 0,660.
CONCLUSION: COLA scoring systems predict, with reasonable accuracy, the risk of SSI in rectal cancer patients undergoing
elective rectal surgery.
