目的:探讨进展期胃癌淋巴结螺旋CT增强三期的强化特征,了解胃癌侵及范围和淋巴结转移数量等状况,对胃癌术前TNM分期的临床价值。方法:对56例经病理证实为进展期胃癌的患者,口服水经多层螺旋CT三期增强扫描,了解胃癌侵及范围和淋巴结转移的部位及数量,评价多层螺旋CT增强三期对进展期胃癌淋巴结转移的敏感性和特异性。结果:56例进展期胃癌淋巴结转移的检出率为93%。其中胃小弯部淋巴结16例、贲门部淋巴结12例、胃大弯部淋巴结9例、腹腔干淋巴结8例、幽门部淋巴结5例、脾淋巴结2例。结论:多层螺旋CT增强三期对进展期胃癌淋巴结转移具有较高的敏感性,为临床术前分期及治疗方式选择提供重要依据。
Objective: To investigate the enhanced features of lymph node spiral CT in the third stage of advanced gastric cancer and to understand the clinical value of preoperative TNM staging of gastric cancer in order to understand the extent of gastric cancer invasion and lymph node metastasis. Methods: 56 cases of pathologically confirmed advanced gastric cancer patients, oral water by three-phase multi-slice spiral CT scan to understand the extent of invasion and lymph node metastasis of gastric cancer sites and the number of evaluation of multi-slice spiral CT enhanced the third phase of the progress Sensitivity and specificity of lymph node metastasis of gastric cancer. Results: The detection rate of lymph node metastasis in 56 cases of advanced gastric cancer was 93%. Including gastric lymph node in 16 cases, cardiac cardia lymph node in 12 cases, 9 cases of gastric benign lymph node, 8 cases of celiac lymph nodes, pyloric lymph nodes in 5 cases, 2 cases of splenic lymph nodes. CONCLUSION: MSCT enhances the sensitivity of three stages to lymph node metastasis of advanced gastric cancer and provides an important basis for clinical preoperative staging and treatment options.
