Double Contrast Diagnosis of Small and Micro Gastric Carcinoma at the Beginning of Early Gastric Carcinoma / 实用放射学杂志

ABSTRACT

Objective:To improve the diagnostic accuracy of double contrast radiography of small and micro gastric carcinoma.Methods:The X-ray findings of small gastric carcinoma(9 cases)and micro-gastric carcinoma(3 cases) proved by surgical pathology were analyzed and compared with pathologic finding.1 misdiagnosed cases and 1 missed cases were analyzed.The double contrast films of acute gastric ulcer were reviewed and differentiated with SGC and MGC.Results:8 cases were examined by the double contrast procedure before gastroscopy,4 were diagnosed small gastric carcinoma,1 was diagnosed micro-gastric carcinoma,1 was misdiagnosed ulcer and 1 was missed,1 was suspected of being carcinoma.4 were examined by the double contrast procedure after gastroscopy,2 were small gastric carcinoma and 1 was micro-gastric carcinoma,which accorded with gastroscopy finding.One of micro-gastric carcinoma missed by gastroscopy was detected by DC.Conclusion:The imaging method of double contrast examination is the most effective one in detecting and diagnosing early gastric cancer.The detecting rate should be obviously increased by combining with gastroscopy closely.
