目的:探讨口服法小肠双对比造影检查及病变表现特点。方法:辅以高、低张药物,口服80%(w/v)硫酸钡200ml加经肛门逆行注入空气2000ml进行小肠双对比造影检查,显示双对比小肠影像。结果:147次小肠造影检查中118例成功地用该方法进行小肠双对比造影检查,成功率80.27%,年龄14岁至69岁,平均34.3岁。118例中阳性32例,阳性显现率27.12%,病理证实的25例,占阳性病例的78.13%。不能应用高、低张药物和逆行注气失败的共29例,占19.73%。小肠肿瘤、Crohn’s病、Meckel’s憩室和回肠末段淋巴滤泡增生症小肠疾病的双对比影像具有特征性表现。结论:(1)此法小肠双对比造影检查简便易行,适合各类有电视X线机的放射科开展。(2)小肠病变在双对比影像上表现特征明显,易于诊断。(3)不能应用高、低张药物和肛门括约肌松弛的患者用此法检查将受到限制。
OBJECTIVE: To investigate the double comparison contrast-enhanced imaging and lesion characteristics of oral small intestine. Method: supplemented with high and low doses of drugs, oral 80% (w / v) barium sulfate 200ml retrograde anus retrograde injection of air 2000ml double contrast small bowel contrast examination, showing double contrast small intestine imaging. Results: In the 147 small bowel radiography examinations, 118 cases were successfully examined by this method. The success rate was 80.27%, ranging from 14 to 69 years (average 34.3 years). Of the 118 cases, 32 were positive, the positive rate was 27.12%, and 25 were pathologically confirmed, accounting for 78.13% of the positive cases. Can not use high, low-dose drugs and retrograde insufflation of a total of 29 cases, accounting for 19.73%. Double contrast images of small bowel tumors, Crohn’s disease, Meckel’s diverticula, and small intestinal diseases of the distal ileal lymphoid follicular hyperplasia have characteristic signs. Conclusions: (1) This method of double contrast contrast examination of small intestine is simple and convenient, suitable for all types of radiology with television X-ray machine to carry out. (2) small bowel lesions in the dual contrast imaging characteristics of the obvious, easy to diagnose. (3) can not be applied to high and low Zhang drugs and anal sphincter relaxation in patients with this method will be limited.
