结直肠癌并肠梗阻的CT术前评估

Preoperative evaluation of colorectal cancer complicated with intestinal obstruction through CT Examination

目的:探讨结直肠癌致机械性肠梗阻通过螺旋CT检查进行手术前评估。方法:收集术前腹部CT并经手术或纤维结肠镜病理证实为结直肠癌引起机械性肠梗阻病例50例,对CT及腹部平片表现进行分析①梗阻近、远侧肠管表现;②梗阻部位改变;③并发症的CT征象。结果:50例肠梗阻中,判断肠梗阻的有无,CT检查诊断50例(100%),X线平片诊断47例(94%)。肠梗阻病因的判断,CT诊断50例(100%),X线平片诊断0例(0%)。全组50例在CT上均见肠腔内软组织肿块影、肠壁增厚和肠腔狭窄。结论:结直肠癌引起机械性肠梗阻的CT检查诊断梗阻的原因、部位、程度及发病缓急,可为临床医生提供更有价值的术前资料。

Objective： To explore the clinical value of preoperative evaluation of colorectal cancer complicated with intestinal obstruction through CT examination.Methods： CT and abdominal plain film data of 50 patients with colorectal cancer complicated with intestinal obstruction confirmed by operation and fibercolonscopy pathological examination were retrospectively analysed.Results： The diagnostic accordance rate of abdominal plain film examination was only 47 patients（94%） before operation.It was raised to 100% with the help of CT examination.The etiologic judgment accordance rate of abdominal plain film examination was 0%.But It was raised to 100% with the help of CT examination.Conclusion： CT examination provides more valuable information for the diagnosis in the the cause of obstruction,obstructive sites and severities.CT examination is important to guide preoperative evaluation.
