本文分析了150例直径>2cm的巨大胃溃疡的临床表现。指出其年龄、发病症状、并发症及大便隐血试验阳性等对两者鉴别无重要意义。并且不能因胃酸正常而忽视溃疡型胃癌的存在。X线钡餐、纤维胃镜检查是鉴别良、恶性溃疡的重要手段,但最后确诊仍需赖于手术与病理证实。 This article analyzed the clinical manifestations of 150 cases of giant gastric ulcers >2cm in diameter. It was pointed out that their age, onset symptoms, complications and fecal occult blood test were not significant for the identification of the two. In addition, the presence of ulcerative gastric cancer cannot be ignored due to normal gastric acidity. X-ray barium meal and fiberoptic gastroscopy are important methods to identify benign and malignant ulcers, but the final diagnosis still depends on the confirmation of surgery and pathology.
