摘要： 目的比较研究超声、腹部X线平片、双源CT（DSCT）3种影像检查技术在结肠肿瘤性肠梗阻诊断中的价值。方法回顾性
分析2010年10月~2011年8月因腹痛至我院急诊科就诊，最后手术证实为结肠肿瘤性肠梗阻且术前均行腹部B超、X线平片及
DSCT 3种检查的45例患者的临床资料，对诊断结果进行分析。结果DSCT对结肠肿瘤性肠梗阻的诊断符合率明显高于超声
（P<0.01）与X线平片（P<0.001），对梗阻部位的判断正确率也优于超声（P<0.01）和X线平片（P<0.001）。DSCT在完成常规肠梗
阻检查的基础上还能进行双能成像，取得患者的血管信息。结论与超声和X线平片相比，DSCT因其可通过三维重建获得更全
面的信息对诊断结肠肿瘤性肠梗阻更为有效，尽管价格相对昂贵，但是不失为临床医生值得考虑的检查手段。综合运用上述三
种检查手段，既能快速、准确解决肠梗阻的诊断问题，又能减轻患者的经济负担。

Abstract: Objective To study the value of ultrasound, abdominal X-ray, and dual-source CT (DSCT) in the diagnosis of colon
tumor obstruction. Methods A retrospective analysis was conducted among 45 patients who were admitted to our department
between October 2010 and August 2011 for abdominal pain. All the patients underwent ultrasound, abdominal X-ray and
DSCT examinations and subsequent surgical interventions, which confirmed the diagnosis of colon tumor obstruction. Results
DSCT diagnosis was obviously more efficient than ultrasound and X-ray in detecting colon obstruction by neoplasms, and
could better predict the position of the obstruction. Complete information of the vessels in the surgical field could be obtained
by DSCT imaging three-dimensional reconstruction. Conclusion Compared with ultrasound and X-ray, DSCT is more effective
in the diagnosis of colon tumor obstruction by acquiring more thorough information by imaging reconstruction and should be
considered for a rapid and accurate diagnosis.
