结肠癌合并急性肠梗阻的CT诊断

目的分析CT在结肠癌所致急性肠梗阻的诊断价值。方法回顾性分析17例结肠癌合并肠梗阻患者（均经手术证实）的CT资料，其中11例加做CT增强扫描，分析其图像特点并与手术结果对照分析。结果梗阻部位分别为：盲肠区3例，升结肠1例，横结肠1例，降结肠2例，乙状结肠10例。与手术结果对照，CT对梗阻的定位诊断准确率为94％（16／17），定性诊断正确率为70％（12／17）。结论CT可以较清晰地显示梗阻部位，对结肠癌合并肠梗阻的定性诊断也有一定价值。

The CT diagnostic value of emergency intstinal obstruetion caused by colon carcinoma

Objective To analyze the value of CT in the diagnosis of emergency intestinal obstruction （EIOB） caused by colon carcinoma. Methods 17 cases with EIOB caused by colon carcinoma were submitted to CT scanning. Contrast enhanced scans were performed in 11 cases. The locations and characters of EIOB in CT imaging were recorded and compared with operation results. Results The locations of the obstructions were 3 cases in cecum, 1 in ascending colon, 1 in transverse colon, 2 in descending colon, and 10 in sigmoid colon. Compared with operation results, the accuracy of CT in locating obstruction was 94%, and in qualitative diagnosis of colon carcinomas was 70%. Conclusion CT can display very well the obstruction location of EIOB, and It has certain value in character izing colon carcinoma with EIOB.
