本文讨论了用于评估疝外科手术质量与并发症的三项关键指标：手术部位感染（SSI）、手术部位事件（SSO）及需要干预的手术部位事件（SSOPI）。SSI 细分为浅层、深层和器官腔隙感染，提供了对不同感染严重程度的深入理解；SSO 包括血清肿、切口裂开等伤口相关事件，虽然扩展了并发症的定义，但不足以完全反映手术质量；SSOPI 则聚焦于需干预的并发症，但未涵盖非手术管理。Clavien-Dindo 分级系统作为评价外科并发症更全面的工具，涵盖了手术并发症的多重层面，但仍需建立符合中国实际的切口不良事件评分体系，以进一步优化术后管理和个体化治疗。

This article discusses three key indicators for evaluating the quality and complications of hernia and abdominal wall surgery： Surgical Site Infection （SSI）， Surgical Site Occurrence （SSO）， and Surgical Site Occurrences Requiring Procedural Interventions （SSOPI）.SSI is categorized into superficial，deep， and organ cavity infections， providing an in-depth understanding different infections severity.SSO includes wound-related events such as seroma and incision dehiscence， which expanding the definition of complications， but not fully reflect surgical quality.SSOPI focuses on complications requiring intervention but does not encompass non-surgical management.The Clavien-Dindo classification system serves as a more comprehensive tool that addresses multiple facets of surgical complications.However， it is necessary to establish a scoring system for adverse surgical events tailored to the actual situation in China， to further optimize postoperative management and individualized treatment.
