摘要
目的探讨多层螺旋CT(MSCT)对肿瘤性肠梗阻的诊断价值。资料与方法分析39例经手术病理证实的肿瘤性肠梗阻术前MSCT表现及对原发性恶性肿瘤TNM分期与临床手术和病理结果对照研究。结果(1)MSCT对肿瘤性肠梗阻的诊断准确性为100%(39/39);对引起梗阻的肿瘤定位诊断准确性为100%(39/39),定性诊断准确性为97.4%(38/39)。(2)滑动薄层块最大密度投影(STS-MIP)后处理技术可显示27例(27/39,69.2%)肿瘤的供血动脉及引流静脉。(3)MSCT对27例肠道原发性恶性肿瘤性梗阻的肿瘤TNM分期的准确性分别为92.6%(25/27)、85.2%(23/27)和100%(27/27)。结论MSCT是术前无创性诊断肿瘤性肠梗阻的重要方法,对引起梗阻的肿瘤的定位、定性及TNM分期判断准确性高,能较好地显示肿瘤的供血血管,对评估肿瘤可切除性及制定治疗方案具有重要意义。
Objective To evaluate the role of MSCT （multi-slice helical spiral CT） and its post processing techniques in the diagnosis of neoplastic intestinal obstruction. Materials and Methods MSCT features of 39 cases of tumorous ileus were analyzed and compared with the results of surgical findings and pathology. Results （ 1 ） The accuracy and qualitative of diagnosis of intestinal obstruction by neoplasm were 100%, 97.4%, respectively. （2） The 69.2% of feeding artery and draining vein of tumors could be revealed by STS MIP. （3） The MSCT overall diagnostic accuracy for TNM preoperative staging of the primary malignant tumor in tumorous ileus was 92.6%, 85.2%, and 100% respectively, compared with the results of surgical findings and pathology. Conclusion MSCT has an important clinical value in orientation and qualitative of diagnosis of neoplastic intestinal obstruction, it can clearly depict feeding artery and draining vein of tumors.
