摘　　要：目的探讨多层螺旋CT(MSCT)在急性肠脂垂炎(Acute epiploic appendagitis,AEA)的临床诊断价值及对该病发病机制的探索。方法收集本院2014年7月~2018年12月急性肠脂垂炎患者资料22例,完善相关的人体学指标,并按照中国成年人体质指数分为4组(轻体重、健康体重、超重、肥胖),所有患者行中下腹CT扫描,观察病灶的部位、形态、密度、大小、边缘及邻近脂肪组织等表现。结果本组22例患者病灶均位于结肠前外侧壁,9例位于盲肠,7例位于乙状结肠与降结肠交界处,4例位于降结肠,1例位于乙状结肠,1例位于结肠肝曲,所有病例均表现为典型的“环征”,中央卵圆形脂肪密度,边缘环形软组织密度,周围脂肪密度增高;通过临床资料分析,本病好发于青壮年,男性多于女性,随着BMI指数增加,发病率有上升趋势。结论急性肠脂垂炎在MSCT上表现为典型的“环征”,结合相关的临床资料,如年龄、性别、体重,能够达到方便、快捷的诊断。Objective To investigate the clinical diagnostic value of multi-slice spiral CT(MSCT)in acute epiploic appendagitis(AEA)and explore the pathogenesis of the disease.Methods The data of 22 patients with AEA from July 2014 to December 2018 in our hospital were collected to improve relevant anthropometric indexes.According to the body mass index(BMI)of Chinese adults,the patients were divided into 4 groups(lightweight,healthy weight,overweight,obesity).All patients underwent CT scans of the lower and middle abdomen to observe the location,shape,density,size,edge and adjacent adipose tissue of the lesions.Results The focus of 22 patients in this group was located in the anterior lateral wall of the colon,9 cases in cecum,7 cases at the junction of sigmoid colon and descending colon,4 cases in descending colon,1 case in sigmoid colon and 1 case in hepatic flexure of the colon.All cases showed typical‘ring sign’,with central oval fat density,marginal annular soft tissue density and increased peripheral fat density.According to the analysis of clinical data,the disease was more frequent in young adults and more common in men than in women.With the increase in BMI,the incidence rate had an upward trend.Conclusion AEA is a typical‘ring sign’on MSCT.Combined with relevant clinical data,such as age,sex and weight,it achieves convenient and rapid diagnosis.
