目的 :探讨进展期胃癌的CT检查方法及表现 ,并对胃癌手术可切除性的术前评估进行研究 ,以避免不必要的剖腹手术。方法 :分析 5 0例经胃镜活检和 /或手术病理证实的进展期胃癌的CT表现 ,并根据肿瘤的生长情况进行手术可切除性的前瞻性评估。结果 :胃底贲门癌 1 3例 ,胃体癌 2 2例 ,胃窦癌 9例 ,病变占据两个分区以上者 6例。 5 0例胃癌均显示胃壁有不同程度的增厚 ,部分胃壁有软组织肿块形成 ,粘膜面有溃疡形成 ,胃腔及贲门狭窄 ,贲门管壁增厚 ,食道下段受累以及周围组织器官侵犯等。结论 :CT对进展期胃癌的定位定性诊断与胃镜活检和 /或手术病理符合率较高 ,肿瘤检出率可达 1 0 0 %。CT对术前肿瘤的可切除性评估有较高的参考价值 ,手术前判断为可切除组的病例手术切除率达 94 .3%。胃癌术前CT诊断具有重要临床意义 ,值得推广应用
Objective: To explore the method and performance of CT examination of advanced gastric cancer, and to study the preoperative evaluation of resectability of gastric cancer in order to avoid unnecessary laparotomy. Methods: CT findings of 50 cases of advanced gastric cancer confirmed by gastroscope biopsy and / or surgical pathology were analyzed and prospectively evaluated for resectability according to the growth of the tumor. Results: There were 13 cases of gastric cardia and stomach cancer, 22 cases of gastric cancer and 9 cases of gastric antrum cancer. The lesions accounted for 6 cases in more than two sections. Fifty cases of gastric cancer showed varying degrees of thickening of the stomach wall, part of the stomach wall with soft tissue mass formation of mucosal ulcers, gastric cavity and cardia stenosis, cardiac wall thickening, lower esophagus involvement and surrounding tissue and organ invasion. Conclusion: The coincidence rate of CT localization of advanced gastric cancer with gastroscopic biopsy and / or surgical pathology is high, and the detection rate of tumor is up to 100%. CT on the resectability of tumor preoperative evaluation has a higher reference value, the resection group was diagnosed before surgery as the surgical resection rate of 94.3%. Preoperative CT diagnosis of gastric cancer has important clinical significance, it is worth promoting
