Objective: The aim of our study was to explore the incidence, pathogenesis and clinical features of malignant change of gastric ulcer. 目的:研究胃溃疡癌变的发病率、发病机理及临床特点。
Conclusion Double contrast examination is very important effection for the differential diagnosis of benign and malignant ulcer of stomach. 结论胃双对比造影检查对胃良、恶性溃疡的鉴别诊断起着重要的作用。
Prospective evaluation of features suggestive of malignant ulcer and biopsy number in the diagnosis of early gastric carcinoma 恶性溃疡的胃镜特征、活检取材数目与早期胃癌阳性率的关系
Evaluation of benign and malignant gastric ulcer with spiral CT 螺旋CT诊断胃良恶性溃疡的评价
The main X-ray manifestations of gastrointestinal meal barium of primary malignant tumors of the small bowel were stenosis, filling defect, stiffness of involved intestinal wall with destruction of mucosa and loss of valvulae conniventes, intestinal obstruction or intussuseption, dynamic dilatation and ulcer. 消化道钡餐主要X线表现为胸腔狭窄,肠腔内充盈缺损,管壁僵硬,粘膜破坏,环状皱壁消失,肠梗阻或肠套叠,肠管扩张及溃疡形成。
The rate of malignant change in gastric ulcer is 1%. 胃溃疡癌变率为1%左右。
Thirty-one patients with various advanced malignant tumors of the upper digestive tract were divided into three types according to their endoscopic characteristics, which included eminence type ( 17 cases), flat type ( 19 cases) and ulcer type ( 4 cases). 31例各种晚期上消化道恶性肿瘤患者,以生长方式分为隆起型(17例),平坦型(10例)和溃疡型(4例)。
