多层螺旋CT诊断小肠肿瘤的临床研究

Clinical application of multi-slice spiral CT in the diagnosis of small intestinal tumors

目的探讨多层螺旋CT诊断小肠肿瘤的临床效果。方法选取2009年1月至2012年12月收治的40例原发性小肠肿瘤患者,均经病理及手术证实,对临床影像学资料行回顾性分析,并对比多层螺旋CT(MSCT)、全消化道钡餐和B超检查结果。结果 40例患者中,腺瘤2例,小肠腺癌19例,恶性淋巴瘤9例,间质瘤10例。MSCT阳性检出率为80.0%(32/40),钡餐造影阳性检出率为42.5%(17/40),B超阳性检出率为15.0%(6/40),MSCT显著优于其他检查方法,差异有统计学意义(P<0.05)。结论多层螺旋CT对小肠肿瘤有较高确诊率,使小肠肿瘤检出的特异性和灵敏度显著提高,且易于在基层医院普及,为有效的检查小肠原发性肿瘤的方法。

Objective To investigate the clinical effect of small intestinal tumor with multilayer spiral CT diagnosis.Methods From January 2009 to December 2012,40 cases of primary small intestinal tumor patients were collected and confirmed by pathology and operation,the clinical imaging data analyses, and comparison of MSCT,gastrointestinal barium meal,B ultrasound examination results.Results Of the 40 patients,2 cases of adenoma,19 cases of small intestinal adenocarcinoma,9 cases of malignant lymphoma,10 cases of gastrointestinal stromal tumors.The MSCT positive rate was 80.0%（32 /40）,barium meal examination positive rate was 42.5%（17 /40）,B-type ultrasound positive rate was 15.0%（6 /40）,MSCT was significantly better than the other methods,the difference was statistically significant（P 0.05）.Conclusions The diagnosis of intestinal tumor,multi-slice spiral CT has a high diagnostic rate,make the small intestinal tumor detection specificity and sensitivity increased significantly,and is easy to be popularized in basic level hospital,is an effective examination of primary small intestinal tumor.
