目的:探讨CT结肠成像(CTC)检查对胃癌结肠早期转移的诊断价值。方法:选取2013年1月-2015年12月我院8例行术前CTC检查的胃癌患者。虽然在轴位断层图像上没有看到明显的腹膜小结节,但是在三维(3D)空间图像中可以见到结肠壁变形。而相应地,在多平面重组图像(MPR)显示由于结肠壁增厚导致的肠壁变形,同时,还观察到与胃癌原发灶相关的密集索条状结构以及增厚的结肠壁。结果:我们发现胃癌病灶周围的索条状硬结节与腹膜侵袭相关,并在术中探查发现这些结节分布在胃癌原发灶、胃结肠韧带以及横结肠系膜之间;我们还观察到结肠结节与腹膜侵袭结节一致。结论:将来CTC有可能被应用于鉴别胃癌经腹膜浸润结肠。
Objective: To investigate the diagnostic value of CT colonography (CTC) in the early metastasis of colonic cancer. Methods: From January 2013 to December 2015, 8 patients with GC in our hospital underwent CTC. Although no obvious peritoneal nodules are seen on the axial tomographic images, deformation of the colon wall can be seen in three-dimensional (3D) space images. Accordingly, the multiplanar reconstructed image (MPR) shows deformation of the intestinal wall due to the thickening of the colon wall, while dense cord-like structures associated with the primary gastric cancer and thickening of the colon wall are also observed. RESULTS: We found that the cord-like tuberous nodules surrounding gastric lesions were associated with peritoneal invasion and were found during surgery to be located between the primary gastric cancer, the colonic ligament, and the transverse mesentery. We also observed that the colon Nodules and peritoneal invasion of nodules line. Conclusion: In the future CTC may be applied to differentiate gastric cancer from peritoneal infiltration colon.
