16层螺旋CT与钡灌肠在结直肠癌诊断的对比研究

Comparative Study of Barium Enema and 16-Multislice Helical CT in Preoperative Diagnosis of Colorectal Carcinoma

目的:探讨16层螺旋CT在中晚期结直肠癌诊断中的应用价值。材料与方法:对35例经病理证实的结直肠癌病人进行回顾性分析。通过MS-CTC检查进行术前Duke’s分期,并与手术病理分期对照分析。结果:BE检查32例,BE对结直肠病变的敏感度为97.5%,准确度为84.4%;MS-CTC检查35例,MS-CTC对结直肠病变的敏感度为100%,准确度为91.4%。MS-CTC对Duke’s分期诊断准确度率为85.7%。结论:BE是结直肠癌的常规影像学检查方法,MS-CTC检查能够提供多方面的诊断信息,对结直肠癌的诊断及术前分期都有重要价值。

Objective： To evaluate the diagnostic value of 16 multi-slice helical CT angiography（CTC） in colo-rectal carcinoma. Material and Methods： 35 patients with histological proven colon or rectal carcinoma were included in this study. 32 patients of them were examined by barium enema（EB）, all of them were examined by MS-CTC in pre-operation. The preoperative staging of Duke＇s were used based on the findings of MS-CTC. The results of MS-CTC were compared with those of surgical and pathological examination in all patients. Result： Among 32 patients were examined by EB, the diagnostic sensitivity of BE was 97.5%, and the accuracy was 84.4%. Among 35 patients were examined by MS-CTC, the diagnostic sensitivity of MS-CTC was 100%, and the accuracy was 91.4%. Thirty cases were correctly staged with Duke＇s, the accuracy was 85.7%. Conclusion： BE can be considered as a primary approach for diagnosing colorectal carcinoma. MS-CTC examination can provide miscellaneous diagnostic information and can be of great value in diagnosing and preoperative staging of the colorectal carcinoma.
