目的探讨低张十二指肠双对比造影及多层螺旋CT对原发性十二指肠肿瘤的诊断价值。方法回顾性分析19例经手术或胃镜活检组织病理证实的原发性十二指肠肿瘤影像资料,其中13例行低张十二指肠双对比造影,16例行多层螺旋CT扫描,10例行低张十二指肠双对比造影+多层螺旋CT扫描。结果与组织病理结果进行对照,低张十二指肠双对比造影诊断符合10例,多层螺旋CT扫描诊断符合14例,10例行低张十二指肠双对比造影+多层螺旋CT扫描者均明确诊断;患者低张十二指肠双对比造影表现为肠管内充盈缺损、溃疡、肠腔狭窄、管壁僵硬、黏膜破坏或受压变形;多层螺旋CT扫描表现为类圆形或形态不规则的软组织肿物向腔内或腔外生长、十二指肠壁增厚或伴有淋巴结肿大及远处转移。结论原发性十二指肠肿瘤低张十二指肠双对比造影及多层螺旋CT表现具有一定特征,二者联合检查可提高诊断准确率。
Objective To investigate the diagnostic value of dual-contrast low contrast duodenoscopy and multi-slice spiral CT in the diagnosis of primary duodenal tumors. Methods A retrospective analysis of 19 cases of primary duodenal tumor confirmed by histopathology and biopsy of operation or gastroscopy was performed. Among them, 13 cases underwent double-contrast low contrast duodenoscopy, 16 cases underwent multislice CT scan, 10 Routine low-duodenal contrast imaging + multi-slice spiral CT scan. The results were compared with the histopathological findings. The double-contrast low contrast duodenoscopy was diagnosed in 10 cases. The multi-slice spiral CT scan was performed in 14 cases and the low-duodenal double contrast angiography + multi-slice spiral CT scan in 10 cases Were clearly diagnosed; patients with duodenal low contrast double contrast angiography showed filling defects within the intestine, ulcers, intestinal stenosis, wall stiffness, mucosal damage or compression deformation; multi-slice spiral CT scans showed round or Irregularly shaped soft tissue mass to the cavity or cavity growth, thickening of the duodenum wall or accompanied by lymph node enlargement and distant metastasis. Conclusions Double duodenal contrast imaging and multi-slice spiral CT in primary duodenal tumors have certain characteristics. The combination of the two can improve diagnostic accuracy.
