目的：探讨胃高位溃疡的临床特点及良恶性溃疡的鉴别。方法：分析经胃镜证实的胃高位溃疡１２６例；其中，良性５６例，恶性７０例。结果：胃高位溃疡男性占７９．２９％，女性２０．７１％；其中，恶性溃疡男性占７５．５６％，女性２４．４４％。５６例患者中，胃镜恶性溃疡检出率（５３．５７％）高于Ｘ线检出率（３５．７１％）（Ｐ＜０．０５）。结论：胃镜检查可提高恶性溃疡的检出率。
Objective: To investigate the clinical characteristics of gastric ulcer and differential diagnosis of benign and malignant ulcers. Methods: 126 cases of gastric ulcer confirmed by endoscopy were analyzed. Among them, 56 cases were benign and 70 cases were malignant. Results: The gastric ulcer accounted for 79.29% of men and 20.71% of women. Among them, malignant ulcers accounted for 75.56% of men and 24.44% of women. Among the 56 patients, the detection rate of gastric ulcer (53.57%) was higher than that of X-ray (35.71%) (P <0.05). Conclusion: Gastroscopy can improve the detection rate of malignant ulcer.
