多层螺旋CT在结肠憩室炎诊断中的价值

Value of multi-slice helical CT for diagnosing colonic diverticulitis

目的分析结肠憩室炎MSCT表现,以提高对该病的认识和诊断水平。方法回顾性分析11例经结肠镜检或手术病理证实结肠憩室炎病例的临床及MSCT资料,并结合文献复习。所有病例均作腹盆部CT平扫检查,其中2例加作CT增强检查,总结结肠憩室炎的MSCT表现特征。结果 CT表现为结肠肠壁囊袋状突出并周围脂肪密度增高10例,其中憩室内粪石7例,仅表现为肠壁周围脂肪密度增高及气腹征者1例,结肠肠壁增厚9例,憩室炎穿孔5例,其中气腹3例,合并出血1例。结论 MSCT能较好的显示结肠憩室炎病变及其并发症,对结肠憩室炎有较高的诊断价值。

Objective To determine the multi-slice spiral computed tomography（MSCT）features of colonic diverticulitis. Methods The clinical information and MSCT of 11 patients with pathologically confirmed colonic diverticulitis were retrospectively analyzed.Results CT showed colonic diverticula with surrounding fat stranding（10）and fecalith in the diverticula（7）,pericolonic fat stranding and pneumoperitoneum（1）,colon wall thickening（9）,bowel perforation（5）with pneumoperitoneum（3）and hematoma（1）. Conclusion MSCT displays clearly the pathological changes and complications of colonic diverticulitis.
