手术后化脓性腹膜炎的发生与患者腹膜及腹膜腔局部宿主防御功能密切相关。免疫功能受抑制的患者,术后发生包括化脓性腹膜炎在内的感染性并发症的风险大大增加。研究表明,腹膜及腹膜腔内的间皮细胞、巨噬细胞、多形核白细胞、成纤维细胞所产生的多种细胞因子及趋化因子在腹膜及腹膜腔局部免疫应答中起重要作用。它们吸引并活 The occurrence of purulent peritonitis after surgery is closely related to the local host defense function in peritoneum and peritoneal cavity. Patients with suppressed immune function have a significantly increased risk of postoperative infectious complications, including purulent peritonitis. Studies have shown that peritoneal and peritoneal cavity mesothelial cells, macrophages, polymorphonuclear leukocytes, fibroblasts produced by a variety of cytokines and chemokines in the peritoneal and peritoneal cavity local immune response plays an important role. They attract and live
