摘要:
Objective To explore the diagnostic features of small bowel intussusception by color Doppler ultrasound in children requiring surgey treatment.Methods A total of 86 children with small intussusception were analyzed retrospectively, they were divided into operation group(n=20) and non-operation group(n=66).The operation group was treated by operation and pathology,the nonoperative group was treated with 24 h internal review of cases of ultrasound reduction.All the cases were examined by color Doppler ultrasonography.The ultrasonographic features of the two groups were compared and summarized. Results In the operation group,the average diameter of small bowel intussusception was (3.0 ±0.4)cm,the average length of sleeve shaft was(5.8±0.6)cm,the average thickness of the outer wall of the sleeve was(0.7±0.3)cm.In non-operative group,the average diameter of small bowel intussusception was(1.7±0.3)cm,the average length of sleeve shaft was(3.3±0.7)cm,the average thickness of the outer wall of the sleeve was(0.2±0.1)cm,there were significant difference between two groups(all P<0.01).In the operation group,primary small bowel intussusception was found in 8 cases,with 7 cases of Meckel's diverticulum,with 3 cases of allergic purpura,with 1 case of intestinal duplication malformation,with 1 case of intestinal polyp.The non operative group was not found pathological precursor by ultrasonography.Conclusion Children with small bowel intussusception who requiring surgery treatment shows the characteristics of larger diameter of the sleeve,longer sleeve shaft,intestinal wall edema and mostly secondary. Understanding these features is helpful to improve the accuracy of diagnosis and assist clinicians in surgical treatment and reduce complications.%目的 探讨需手术治疗的小儿小肠套叠的彩色多普勒超声诊断特点.方法 回顾性分析86例小儿小肠套叠病例资料,分为手术组(20例)和非手术组(66例),手术组为经手术治疗及病理证实的病例,非手术组为未经手术治疗24 h内复查超声复位的病例.均行彩色多普勒超声检查,并对两组的超声图像特点进行比较分析并归纳总结.结果 手术组小肠套叠套头直径(3.0±0.4)cm,套入部长度(5.8±0.6)cm,套头外层肠壁厚度(0.7±0.3)cm;非手术组小肠套叠套头直径(1.7±0.3)cm,套入部长度(3.3±0.7)cm,套头外层肠壁厚度(0.2±0.1)cm,两组比较差异均有统计学意义(均P<0.01).手术组中原发性小肠套叠8例,小肠套叠伴美克尔憩室7例,伴过敏性紫癜3例,伴肠重复畸形1例,伴小肠息肉1例;非手术组超声检查均未发现病理性先驱物.结论 小儿小肠套叠手术治疗的患儿具有套头直径大、套入部较长、外层肠壁水肿及多为继发性等超声特点,掌握其特点对于选择治疗方案和把握手术时机有重要作用.
