Background/Aims:
Colorectal perforation remains a life-threatening condition associated with high mortality. Various factors and operative procedures have been discussed in regard to prediction of outcome, and several scoring systems have been proposed to predict the outcome of critically ill patients. The present study was undertaken to identify factors and determine predictive scoring systems for the postoperative outcome of patients with colorectal perforation.
Methodology:
Between January 1996 and December 2000, 45 consecutive patients underwent emergency operation for colorectal perforation. Twelve patients (26.7%) died in hospital. The correlation of outcome with various preoperative factors, APACHE II and SOFA scores were assessed retrospectively.
Results:
Univariate analysis showed that outcome was significantly related to maximum SOFA score (p=0.0069). Multivariate logistic regression analysis demonstrated that the maximum SOFA score was an independent predictor (p=0.016). Serum creatinine level (p=0.013) and platelet count (p=0.036) were associated with patient outcome in the SOFA score. Patients with a SOFA score higher than 7 had a greater risk of hospital death (p=0.0085).
Conclusions:
The maximum postoperative SOFA score is a useful predictor of the outcome from surgery for colorectal perforation.
