目的 :加深认识小胃癌 (SGC)及微小胃癌 (MGC)双对比造影 (DC)X线特征 ,提高诊断准确率。方法 :分析讨论经手术病理证实的 9例SGC及 3例MGCDCX线表现并与病理进行对照 ,分析了 2例漏、误诊病例以及与急性胃溃疡的鉴别诊断。结果 :8例胃镜前DC检查 ,检出SGC 4例 ,MGC 1例 ,误诊溃疡 1例 ,漏诊SGC 1例 ,疑诊 1例。 4例胃镜后DC检查 ,检出SGC 2例 ,MGC1例 ,与胃镜符合 ,检出胃镜漏诊MGC1例。结论 :DC是显示SGC及MGC最好的影像学方法 ,与胃镜密切配合可有效提高检出率。
Objective : To deepen the knowledge of dual contrast radiography (DC) features of small gastric cancer (SGC) and tiny gastric cancer (MGC) and improve diagnostic accuracy. Methods: 9 cases of SGC and 3 cases of MGC CDX confirmed by operation and pathology were analyzed and compared with pathology. Two cases of leakage, misdiagnosis and differential diagnosis with acute gastric ulcer were analyzed. RESULTS: Eight cases of endoscopic DC examination revealed 4 cases of SGC, 1 case of MGC, 1 case of misdiagnosis of ulcer, 1 case of missed diagnosis of SGC, and 1 case of suspected diagnosis. 4 cases of gastroscopy after DC examination, 2 cases of SGC were detected, 1 case of MGC was consistent with gastroscopy, and 1 case of misdiagnosis of endoscopic MGC was detected. Conclusion : DC is the best imaging method for displaying SGC and MGC. Close cooperation with gastroscopy can effectively increase the detection rate.
