Abstract

Purpose: The Clavien-Dindo Classification (CDC) and the Comprehensive Complication Index (CCI®) are both widely used methods for reporting postoperative complications. Several studies have compared the CCI® with the CDC in evaluating postoperative complications of major abdominal surgery. However, there are no published reports comparing both indexes in single-stage laparoscopic common bile duct exploration with cholecystectomy (LCBDE) for the treatment of common bile duct stones. This study aimed to compare the accuracy of the CCI® and the CDC in evaluating the complications of LCBDE.

Methods: In total, 249 patients were included. Spearman's rank test was used to calculate the correlation coefficient between CCI® and CDC with length of postoperative stay (LOS), reoperation, readmission, and mortality rates. Student t-test and Fisher's exact test were used to study, if higher ASA, age, larger surgical time, history of previous abdominal surgery, preoperative ERCP, and intraoperative cholangitis finding were associated with higher CDC grade or higher CCI® score.

Results: Mean CCI® was 5.17 ± 12.8. CCI® ranges overlap among three CDC grades: II (20.90-36.20), IIIa (26.20-34.60), and IIIb (33.70-52.10). Age > 60 years, ASA ≥ III, and intraoperative cholangitis finding were associated with higher CCI® (p = 0.010, p = 0.044, and p = 0.031) but not with CDC ≥ IIIa (p = 0.158, p = 0.209, and p = 0.062). In patients with complications, LOS presented a significantly higher correlation with CCI® than with CDC (p = 0.044).

Conclusion: In LCBDE, the CCI® assesses better the magnitude of postoperative complications in patients older than 60 years, with a high ASA as well as in those who present intraoperative cholangitis. In addition, the CCI® correlates better with LOS in patients with complications.
