摘要 目的:分析缺血性结肠炎(IC)的临床、内镜表现与病理特征,探讨结肠镜和病理检查对IC的诊断价值。方法:42例IC患者,均在入院后72h内行结肠镜检查和病理活检,回顾性分析患者的临床、内镜表现及病理特征。结果:本组患者年龄>50岁36例(85.71%),临床表现主要为突发腹痛、腹泻及便血。内镜检查结果显示一过型IC36例(病变呈纵行溃疡者16例,病变呈环形侵及肠腔全周者10例,病变呈散在点状红斑者6例),内镜特点为黏膜充血水肿、糜烂并可见溃疡,病变处与正常黏膜界限清楚。狭窄型IC6例,内镜特点为肠腔明显狭窄、全壁增厚及结肠袋消失。病变部位多位于左半结肠;IC病理特征为黏膜活组织水肿,中性粒细胞浸润,固有层纤维结缔组织增生、出血及小血管内纤维素样血栓及巨噬细胞内有含铁血黄素沉积。结论:中老年人突发腹痛、腹泻及便血时应警惕缺血性结肠炎,内镜结合病理检查是明确诊断及了解病变程度及预后的主要方法。
