原发性小肠肿瘤的影像学诊断价值

The value of imaging examination to primary tumor of small intestine

目的 对手术病理证实的原发性小肠肿瘤28例的影像学检查进行分析,探讨影像学检查的诊断价值。方法 28例小肠肿瘤有20例行CT检查,8例行消化道造影检查,7例行ERCP检查,12例行内镜检查,2例行DSA血管造影检查。结果 28例小肠肿瘤中有16例恶性肿瘤、12例良性肿瘤。恶性肿瘤以腺癌及平滑肌肉瘤为多,良性肿瘤以腺瘤及平滑肌瘤为多。其中CT术前诊断正确率为70％(14/20),消化道造影正确率为72％(6/8),ERCP为82％(6/7),内镜为86％(10/12)。结论 影像学检查是小肠肿瘤诊断的重要手段,多种检查方法的结合可提高诊断的正确率。

Purpose To investigate the value of imaging examination of 28 cases primary tumor of small intestine confirmed by surgery and pathology .Methods 28 cases small intestinal tumor,20 cases were examined by CT, 8 cases were examined by GI,7 cases were examinde by ERCP, 12 cases were examined by endoscopy,2 cases were examined by DSA.Results Malignant tumors of small intestine were found in 16 cases,benign tumors were found in 12 cases. Most of the malignant tumors of small intestine are adenocareinoma and leiomyosarcoma. Most of the benign tumors of small intestine are adenoma and leiomyoma. The preoperative diagnostic accuracy of CT is 70% (14/20) ,GI diagnostic accuracy is 72% (6/8) , ERCP diagnostic accuracy is 82% ,endoscopy diagnostic accuracy is 86% (10/12). Conclusion Imaging examination is a very important method to diagnosis of small intestinal tumor ,different examination methods united can improve diagnostic accuracy of small intestine tumor.
