【摘要】：目的探讨胃腔充盈程度对进展期胃癌肿瘤厚度测量的影响及肿瘤厚度测量的临床意义。方法收集进展期胃癌患者38例(初诊21例,非手术治疗后复诊17例),采用低张气体充盈法,分别于平扫(充盈前)及增强静脉期(充盈后)轴位图像测量并比较胃腔充盈前、后各分区正常胃壁及肿瘤的厚度。同一观察者于1个月后进行再次测量,比较2次测量的一致性。结果各分区正常胃壁充盈前、后厚度的差异有统计学意义(P均0.001),胃体大弯厚度变化最大。胃腔充盈前后初诊胃癌肿瘤厚度差异无统计学意义(P均0.05),而复诊胃癌肿瘤厚度差异有统计学意义(P均0.05)。同一观察者2次测量的肿瘤厚度一致性好。结论初诊进展期胃癌肿瘤厚度相对固定,可作为CT检查的测量指标,复诊时应尽量使胃腔充盈程度与治疗前一致,以准确评价治疗效果。
[Abstract]:Objective to investigate the effect of filling degree of gastric cavity on the measurement of tumor thickness in advanced gastric cancer and its clinical significance. Methods Thirty-eight patients with advanced gastric cancer (21 patients with advanced gastric cancer and 17 patients with non-operative treatment) were examined by hypotonic gas filling method. The axial images of plain scan (before filling) and enhanced vein (after filling) were measured and compared before and after gastric cavity filling. The thickness of normal gastric wall and tumor. The same observer remeasured one month later to compare the consistency of the two measurements. Results before filling the normal gastric wall, the difference of posterior thickness was statistically significant (P = 0.001), and the thickness of the great curvature of gastric body changed the most. There was no significant difference in tumor thickness before and after filling of gastric cavity (P < 0.05), but there was significant difference in tumor thickness between two groups (P < 0.05). The tumor thickness measured twice by the same observer was consistent. Conclusion the thickness of advanced gastric cancer is relatively fixed and can be used as a measure of CT examination. The degree of gastric cavity filling should be consistent with that before treatment in order to evaluate the therapeutic effect accurately.
