超声诊断小儿结肠息肉合并肠套叠的价值

摘要

目的：探讨肠套叠患儿超声检查中发现结肠息肉的诊断价值。方法回顾性分析32例结肠息肉合并肠套叠患者的超声声像图特征。结果32例结肠息肉合并肠套叠的共同超声表现为长轴呈“套筒征”，中央肠腔内见一带蒂的不均匀低回声团，短轴呈“靶环征”，低回声团仍在中央肠腔。本组病例肠息肉最大长径为27mm，最小长径为17mm。32例患儿均经温盐水灌肠复位，再行结肠镜息肉摘除术。结论结肠息肉是引起小儿肠套叠的其一因素，小儿肠套叠又属急诊，及时发现并治疗，对临床有重要价值。%ObjectiveTo explore the diagnostic value of colon polyps by ultrasonic examination in children with intussusception. Methods Thirty two children with colon polyps and intussusception were enrolled in this study,ultrasonic features of these cases were retrospectivelly analyzed.ResultsThe common ultrasonic characters of these 32 cases were:the long axis showed "sleeve" sign,and a heterogeneous hypoechoic stem was found in the central area of the colon,short axis showed "target ring sign",and the heterogeneous hypoechoic stem was still seen in the central area of the colon. The maximum long diameter of colon polyps in these cases was 27mm,and the minimum was 17mm. All of these 32 patients were reset by clyster method with warm saline,then colonoscopy polypectomy were operated to remove colon polyps.ConclusionsColon polyp is the most important risk factor which causes intussusception in pediatric patients,intussusception is an urgent disease in emergency department,detected and treated timely is important in clinical practices.
