The Manifestation of CT Colonography on Detecting Transperitoneal Invasion about Gastric Cancer
-
摘要: 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。Abstract: Objective: To evaluate the diagnostic value of CT colonography (CTC) in detection of transperitoneal invasion from gastric cancer. Method: Eight gastric carcinoma patients underwent CTC for preoperative work-up. Although no obvious peritoneal nodule was seen on axial CT images, colonic wall deformities were noted on three-dimensional (3D) air images. Multiple Planar Reconstruction (MPR) images revealed thickening colonic wall at the deformities, and in addition, we also observed dense cordlike structures which connecting the primary gastric cancer and colonic wall thickening. Results: on one hand, cordlike indurations consistent with peritoneal invasion were found to connect the primary gastric cancer, gastrocolic ligament, and transverse mesocolon during exploratory surgery. On the other hand, we observed colonic scars consistent with peritoneal invasion. Conclusion: All of observations suggest that CTC could be use for the differentiation of gastric cancer and transperitoneal colonic invasion.
