Background: Complications are important indicators of immediate postoperative outcomes. The Clavien–Dindo classification (CDC) is a widely used index for the classification of surgical complications. More recently, the comprehensive complication index (CCI) has also been introduced for classifying postoperative complications. The aim of this study was to compare the relationship of CCI and CDC with clinical or economic parameters. Methods: The study prospectively enrolled patients from April 2015 to October 2016. Two hundred and twenty-two patients underwent pancreatectomy during the enrolled period. Complications were ranked according to CDC and CCI indices. After analyzing the correlation between CCI and CDC, the correlations of length of stay (LOS) and cost with CCI and CDC were compared. Finally, differences between the correlation coefficients of CDC and CCI parameters were calculated. Results: Complications occurred in 211 patients (95.0%). The correlation between CDC and CCI was r = 0.938. (p < 0.001) Compared to the CDC, CCI showed significantly stronger correlations with LOS and cost of complications (LOS: CCI vs. CDC, r = 0.725 vs. r = 0.630, p < 0.001; cost: CCI vs. CDC, r = 0.774 vs. r = 0.723, p < 0.001). Conclusion: CCI is a more accurate classification index, compared to CDC, for evaluating the risk of postoperative complications.
