目的探讨低张双对比造影对胃癌前病变的诊断及病变的影像特征.方法应用低张药物行胃双对比造影,辅以幽门螺旋杆菌(helicobacter pylori HP)13C尿素呼气试验;选取45例疑有胃癌前病变患者再行胃镜及镜下取样病理活检;并将造影所见与胃镜及病理结果比较分析.结果 (1)造影结果与胃镜及病理结果大部分相符,经证实41例(符合率约91%).(2)其主要的X线表现为病变区胃小区的不规则增大、隆起、变形,胃小沟增宽、宽窄不均和粘膜下结节样增生,胃舒张性减低等征象.结论 (1)清晰显示胃小区的改变是诊断的关键.(2)辅以HP检测能明显提高诊断率.(3)胃癌前病变的X线表现有一定的特征性,良好的双对比造影可对大多数病变作出初步诊断.

Objective To investigate diagnose value and lesions image features of the hypotonic double contrast examination in gastric percancancerous lesions. Methods Apply the low tension medicines make double contrast to radiography stomach, assisted by the (helicobacter pylori HP)13C urea breath test;There is again gastroscope and pathologic biopsy of gastroscopce unden taken sample to live check for choose 45 cases suspect that yes gastric precancerous lesions patient;Comparative Analysis to will the double contrast radiography see with the result of gastroscope and pathology. Results (1)41 cases confirmed (coincidence rate about 91%),double contrast radiography results with gastroscope and pathology results the majority accords. (2)It the main x-ray findings for lesion area gastric area irregular increasa, crown now, deformity;gastric grooves broadening and unequal;submucosal nodular hyperplasia; gastric reduced distensibility a series of signs. Conclu-sions (1)The key of diagnosis are the change of clear display gastric area. (2)assisted by the HP measuring can raises the diagnosis rate apparently. (3)There is certain characteristic native in x-ray findings of gastric lesions precancerous, good double contrast radiograpby all righe diagnose most pathological changes preliminarily.
