64排螺旋CT增强扫描对胃肠道上皮内瘤变的诊断价值

Diagnostic Value of 64 Slice Spiral CT Enhanced Scan in Gastrointestinal Intraepithelial Neoplasia

目的探讨64排螺旋CT增强扫描对于胃肠道上皮内瘤变及早期癌的鉴别诊断价值。方法选择2015年5月—2017年6月在本院行手术治疗的25例胃肠道上皮内瘤变患者作为胃肠道上皮内瘤变组,另选择同期在本院行手术治疗的20例胃肠道早期癌变患者作为胃肠道早期癌变组,对比分析两组术前CT诊断和手术病理诊断结果。结果胃肠道上皮内瘤变CT与病理诊断符合率为76.00%。胃肠道早期癌变患者CT与病理诊断符合率为75.00%。胃肠道上皮内瘤变组动脉期值与早期癌变组比较,差异无统计学意义(P>0.05)。胃肠道上皮内瘤变组门静脉值为(43.56±5.24),低于早期癌变组的(52.96±4.03),且平衡值高于早期癌变组的(37.05±1.35),组间对比,差异具有统计学意义(P<0.05)。结论 64排螺旋CT增强扫描在对于胃肠道上皮内瘤变及早期癌鉴别诊断价值较高。

[Abstract] Objective To evaluate the differential diagnosis of cases of gastrointestinal intraepithelial neoplasia and early carcinoma with enhanced scan of 64 slice spiral CT. Methods 25 patients with gastrointestinal intraepithelial neoplasia treated in our hospital from May 2015 to June 2017 were selected as gastrointestinal intraepithelial neoplasia group. In addition, 20 patients with early gastrointestinal cancer in the same period were treated as early gastrointestinal cancer cases. The results of preoperative CT diagnosis and pathological diagnosis were compared and analyzed between the two groups. Results The coincidence rate of gastrointestinal intraepithelial neoplasia （CT） and pathological diagnosis was 76.00%. The coincidence rate of CT and pathological diagnosis was 75.00% in patients with early gastrointestinal cancer. There was no signifcant difference in the arterial phase between the gastrointestinal intraepithelial neoplasia group and the early canceration group （P 〉 0.05）. The value of portal vein in the gastrointestinal intraepithelial neoplasia group was （43.56 ± 5.24）, whichwas lower than the early cancerization group （52.96 ± 4.03）, the balance value was higher than that in the early canceration group （37.05 ± 1.35）, the difference between the two groups was statistically signifcant （P 〈 0.05）. Conclusion The enhanced scan of 64 slice spiral CT is of higher value in differential diagnosis of gastrointestinal intraepithelial neoplasia and early carcinoma.
