X线和CT诊断十二指肠腺癌的效果比较

Comparison of X-ray and CT in the diagnosis of duodenal adenocarcinoma

目的:分析探究十二指肠腺癌诊断中X线和CT诊断的价值。方法:采集研究对象为2017年10月至2019年10月病理检查为十二指肠腺癌患者45例,所有患者均先后采用X线和CT进行诊断,对比两种诊断方式的诊断准确率与应用价值。结果:CT诊断准确率(91.1%)高于X线诊断准确率(64.4%),差异显著有统计学意义,P<0.05;诊断显示有22例十二指肠病变位置在降部,6例于水平部,17例于壶腹部;X线诊断为发病早期组织较软,呈现为结节状,表现为息肉形式,直到中晚期会呈现溃疡与浸润状态,且十二指肠病变部位变硬,阻碍钡剂流通,破坏黏膜组织;CT诊断为发病早期十二指肠病变部位呈现圆形软组织肿块样,发展至中晚期十二指肠病变部位变硬,且指肠变狭窄,肿块逐渐蔓延。结论:由于X线在十二指肠腺癌诊断中存在一定的局限性,因而可将CT诊断应用在十二指肠腺癌诊断中,可明显提高诊断准确率,便于准确发现病变部位,以及病变状况。

Objective To analyze the value of X-ray and CT in the diagnosis of duodenal adenocarcinoma.Methods From October 2017 to October 2019,45 patients with duodenal adenocarcinoma were selected for pathological examination.All patients were diagnosed by X-ray and CT successively.The diagnostic accuracy and application value of the two diagnostic methods were compared.Results The accuracy rate of CT diagnosis (91.1%) was higher than that of X-ray diagnosis (64.4%),the difference was statistically significant (P<0.05);diagnosis showed that there were 22 cases of duodenal lesions in the descending part,6 cases in the horizontal part,17 cases in the ampulla;X-ray diagnosis showed that the early stage of the disease was soft,presented as nodular,presented as polyp form,and presented ulcer and infiltration state until the middle and late stage,and The lesions of duodenum became hard,obstructed the circulation of barium and destroyed the mucosa.CT diagnosis showed that the lesions of duodenum in early stage presented round soft tissue mass,which developed to the lesions of duodenum in middle and late stage,and the intestine became narrow,and the masses gradually spread.Conclusion Because of the limitation of X-ray in the diagnosis of duodenal adenocarcinoma,CT diagnosis can be used in the diagnosis of duodenal adenocarcinoma,which can significantly improve the accuracy of diagnosis,facilitate the accurate detection of lesion location and condition.
