摘　　要：目的探讨高原地区肠气囊肿症(PCI)的多层螺旋CT(MSCT)表现及临床特征。方法回顾性分析164例PCI患者的影像和临床资料。PCI分为3种类型,分别为Ⅰ型(浆膜下型)、Ⅱ型(黏膜下型)、Ⅲ型(混合型)。分析的临床特征包括患者年龄、性别、种族、临床症状以及既往史;影像特征包括PCI分型、病变位置及腹腔游离气体情况并进行统计学分析。结果164例PCI患者中,Ⅰ型32例(19.51%)、Ⅱ型49例(29.88%)、Ⅲ型83例(50.61%)。升结肠受累最多,共81例(49.39%),其次为多节段型36例(21.95%),直肠及小肠受累最少。60.36%PCI患者合并腹腔游离气体,3种类型PCI合并腹腔游离气体率比较差异有统计学意义(χ^(2)=9.04,P=0.011)。结论高原地区PCI以中年男性多见,其中以升结肠受累最常见,1/2以上患者合并腹腔游离气体。MSCT可清晰显示病变受累部位、范围、数量以及肠内外并发症,对高原地区PCI检出具有重要意义。Objective To investigate the multi spiral computed tomography(MSCT)findings and clinical features of pneumatosis cystoides intestinalis(PCI)in the plateau region.Methods Retrospective analysis of imaging and clinical data of patients(164 cases)diagnosed with PCI.PCI was classified into 3 types:type Ⅰ(subserosal),type Ⅱ(submucosal),and type Ⅲ(mixed type).The clinical features analyzed included patient age,gender,race,clinical symptoms,and history;the imaging features included PCI classification,lesion location,and abdominal free gas and were statistically analyzed.Results 164 cases PCI patients were 32 cases(19.51%)of type Ⅰ,49 cases(29.88%)of type Ⅱ,and 83 cases(50.61%)of type Ⅲ PCI were found.The ascending colon was the most involved,with 81 cases(49.39%),followed by the multi-segmental type 36 cases(21.95%),and the rectum and small intestine were the least involved.60.36% of PCI patients were combined with abdominal free gas,and the difference in the rate of combined abdominal free gas among the three types of PCI was statistically significant(χ^(2)=9.04,P=0.011).Conclusion PCI in the plateau region is more common in middle-aged males,among which the ascending colon is the most commonly involved,and more than half of the patients have combined abdominal free gas.MSCT can clearly show the site,scope,and number of lesions involved as well as intestinal and external complications,which is important for the detection of PCI in the plateau region.
