多排螺旋CT对肠梗阻诊断的临床价值

Clinical value of intestinal obstruction diagnosed by multi-detector CT

目的探讨多排螺旋CT(MDCT)诊断肠梗阻的临床价值。方法收集29例经临床手术证实的肠梗阻患者,其中男性18例,女性11例;年龄16～81岁,平均年龄52.3岁。回顾分析其MDCT影像资料,总结其CT影像表现。结果29例肠梗阻患者行手术治疗,小肠梗阻11例,不同部位结肠梗阻15例,直肠梗阻3例。肠道肿瘤18例;肠粘连4例;炎性狭窄2例;肠扭转2例;肠套叠2例,腹壁疝1例。术前MDCT诊断与术后结果对照,梗阻部位符合28例,梗阻原因符合28例,符合率均为96.6%。结论MDCT对肠梗阻的部位、病因的诊断准确率较高,可为临床确定治疗方案提供可靠的依据。

Objective To investigate clinical value of multidetector CT（MDCT） in diagnosis of intestinal obstruction.Methods A total of 29 patients with intestinal obstruction diagnosed by MDCT were enrolled,male 18,female 11,mean age 52.3 years old（range 16-81 years old）.The MDCT images were analyzed and compared with surgery and pathology results.Results The 29 cases intestinal obstruction were performed surgical treatment,11 cases of small bowel obstruction,15 cases of colon obstruction and 3 cases of rectal obstruction.Eighteen cases were intestinal tumors,4 cases intestinal adhesion,2 case inflammation narrow,2 cases intestinal volvulus,2 cases intestinal intussusception and 1 case abdominal mural hernia.The obstruction location and cause diagnosed by MDCT pre-operation were compared,and the accordance with operation and pathology in 28 cases,but only 1 case diagnosed was incorrect.Their coincidence rate was 96.6 %.Conclusion The location and cause of most intestinal obstruction may be correctly diagnosed by MDCT.Larger scale research is need to confirm this result.
