摘要
目的探讨MSCT及三维重建技术在肠梗阻病因诊断中的价值。方法回顾性分析33例经手术病理或临床随访明确诊断肠梗阻的常规腹部CT和MSCT三维重建表现,分别作出相应的病因诊断,并与手术病理或临床随访相对照。比较常规图像(横断面图像)与常规图像结合MSCT三维重建图像诊断肠梗阻的诊断符合率。结果 33例肠梗阻病例中,机械性肠梗阻31例(肿瘤性病变8例、炎性病变4例、腹外疝3例、膈疝1例、肠粘连12例、肠扭转2例、肠套叠1例);麻痹性肠梗阻2例。常规图像单独应用与常规图像结合MSCT三维重建图像诊断肠梗阻的诊断符合率分别为84.8%(28/33)和93.9%(31/33),两者差异无统计学意义(χ2=1.55,P>0.05)。结论 MSCT对肠梗阻病因的诊断具有较高的准确率,结合三维重建有助于提高肠梗阻病因诊断,指导临床及时治疗,减少并发症。
Objective To investigate the value of multislice spiral CT(MSCT) three-dimensional reconstruction in the diagnosis of intestinal obstruction.Methods The routine abdominal CT and MSCT three-dimensional reconstruction imagings of 33 cases with intestinal obstruction,confirmed by surgical pathology or clinical follow-up,were retrospectively analyzed.The diagnoses made according to routine abdominal CT and MSCT three-dimensional reconstruction were compared.Results Among 33 cases 31 were finally diagnosed mechanical intestinal obstruction(8 with neoplastic lesions,4 with inflammatory lesions,3 with hernia,1 with diaphragmatic hernia,12 with adhesions,2 with volvulus,and 1 with intussusception).Two cases were diagnosed paralytic ileus.The diagnostic rates of routine abdominal CT and routine abdominal CT plus three-dimensional reconstruction were 84.8%(28/33) and 93.9%(31/33),respectively,with no significant differences(χ2=1.55,P>0.05).Conclusion MSCT has high accuracy in etiological diagnosis of intestinal obstruction,.Three-dimensional reconstruction can help MSCT to improve the diagnosis rate of intestinal obstruction.Therefore routine abdominal CT plus three-dimensional reconstruction is quite useful in early diagnosis and timely treatment.It can also reduce the incidence of complications.
