The comprehensive complication index (CCI) is a more sensitive complication index than the conventional Clavien–Dindo classification in radical gastric cancer surgery

Background The comprehensive complication index (CCI) integrates all complications of the Clavien–Dindo classification (CDC) and offers a metric approach to measure morbidity. The aim of this study was to evaluate the CCI at a high-volume center for gastric cancer surgery and to compare the CCI to the conventional CDC.
