目的：规范内镜下治疗早期胃癌的诊疗行为，降低内镜下粘膜剥离（Endoscopic Submucosal Dissection，ESD)术后感染发生。方法：目标性监测2018年1月至2022年12月在我院行ESD早期胃癌患者，对比分析感染组与未感染组SAA，CRP和PCT表达水平，住院天数、费用和恢复时间的差异。通过受试者工作特征（ROC）曲线评价CRP、SAA、PCT在ESD术后感染中的诊断价值。结果：SAA，CRP和PCT在感染组中表达明显高于未感染组（P<0.05），PCT对术后感染诊断价值优于CRP和SAA；感染组与未感染组相比，住院天数和费用增加，恢复时间延迟（P<0.05）。结论：PCT有助于指导ESD术后感染临床诊断和抗感染治疗。从卫生经济学和患者预后方面考虑，预防ESD术后感染具有重要临床意义。
