摘要 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 。 Objective:To discuss CT examining techniques and manifestations for gastric carcinoma during progressive period and study possibility of operative excision in gastric carcinoma in order to avoid unnecessary laparotomy.Methods: CT findings of 50 cases with gastric carcinoma during progressive period confirmed by gastroscope biopsy and or operation and pathology were analyzed and prospective evaluation of tumoral respectability according to the vegetal condition of tumors. Results:13 cases of fundus ventriculi caria carcinoma, 22 cases of corpus ventriculi carcinoma,9 cases of antrum pyloricum, 6 cases of the lesions were located over two gastric regions.All cases show the thickness of gastric wall become incrassater in various degree. Some of the cases have tumor grow up in the gastric wall, engender ulcer in mucomembranous surface gastric cavity and cardiac pipe become stricture,the thickness of cardiac wall become incrassater. Low esophagus and perigastric organs were invaded. Conclusion:The accuracy of location and qualitalive diagnosis by CT were considerable and the detecting rate of tumor was 100%.CT has important reference value in preoperative evaluation of tumoral resectability .The excised rate of operable group was 94.3%. CT diagnosis of gastric carcinoma has important value,it may be popularized.
