小肠双重造影对小肠肿瘤的诊断价值

The value of the small bowel tumors in the diagnosis of double contrast radiography

目的 探讨各种类型小肠肿瘤的小肠造影表现及双重造影的诊断价值。方法 回顾性分析 5 3例小肠肿瘤的双重造影表现。结果 病变 1.0× 1.2cm～ 17× 19cm ,<6cm的病变 2 6例。小肠平滑肌肿瘤主要表现为充盈缺损。小肠淋巴瘤病变范围广 ,主要表现为多发结节状充盈缺损 ,伴肠管狭窄及扩张。小肠腺癌主要表现为肠管不规则狭窄 ,肠壁僵硬破坏 ,显示“果核征”。小肠转移瘤主要表现为多发压迹 ,肠管粘连固定。结论 小肠双重造影是目前诊断小肠肿瘤最有价值的方法之一。

Objective To analyze the radiographic findings of the small bowel tumors and to evaluate the importance of the double contrast radiography.Methods 53 patients suffered from the small bowel tumors, in whom male 32, female 21, mean age 47 years old,were examined by double contrast radiography. The radiographic features of the small bowel tumors were reviewed.Results The largest lesion was 17×19cm,the smallest was 1× 1.2cm. The lesions were smaller than 6cm in 26 cases.The radiographic appearances of the leiomyoma and leiomyosarcoma of the small intestine are mainly filling defects.The findings of the lymphoma are multiple nodular filling defects with narrowing and dilatation of the lumen. The manifestations of the adenocarcinoma are irregular stucture with stiff of the bowel wall and called “eating apple” sign. The features of the metastatic tumors are multiple impressions with adhesions.Conclusion One of the best diagnostic methods of the small bowel tumors was double contrast radiography.
