Postoperative complications are important indicators for evaluating surgical outcomes, and mortality and the incidence of various specific complications are often used to measure the efficacy of surgical and perioperative management strategies. With the progress of medical technology, there has been a dramatic decline in mortality and the incidence of complications. As a result, reporting and evaluation in the traditional methods no longer meets the actual needs of the world. There has arisen an urgent need for an instrument of standardized reporting and evaluation. The instrument should be aligned with the actual circumstances and should represent the patient's overall burden of postoperative complications. We herein reviewed the latest research findings on Clavien-Dindo Classification (CDC) system and comprehensive complication index (CCI), two instruments of standardized reporting and evaluation of postoperative complications, and discussed the space for improvement and prospects of application of CDC and CCI.
术后并发症是评估手术结果的重要指标，通常使用死亡率和各种特定并发症的发病率来衡量手术及围术期管理策略的疗效。随着医学技术的进步，死亡率及单一并发症的发病率已经大幅下降，传统的报告及评估方法不能满足现实需要，迫切需要符合实际情况，反映患者术后整体并发症负担的标准化报告及评估工具，本文就术后并发症的标准化报告及评估工具Clavien-Dindo分级（Clavien-Dindo classification, CDC）系统和综合并发症指数（comprehensive complication index, CCI）的研究进展做一综述，并对CCI和CDC的改进空间及应用前景进行了展望。
