北京地区25年来消化性溃疡及胃癌发病情况的演变

目的探讨25年来十二指肠球部溃疡(DU)、胃溃疡、胃癌及幽门螺杆菌(Hp)感染在胃镜检查中发生的改变。方法分析1980年1月至2004年12月于我院进行胃镜检查的所有病例,共计104987例。选择全部DU、胃溃疡、经病理证实的胃癌病例为研究对象,分为10～<20岁、20～<30岁、30～<40岁、40～<50岁、50～<60岁、60～<70岁、70～<80岁及≥80岁8个年龄组。结果DU共13684例,平均检出率为13.03%,1999年以后呈下降趋势;胃溃疡共4398例,平均检出率为4.19%,1996年以后呈下降趋势;胃癌共1732例,检出率波动于1.02%～2.36%之间,平均为1.68%,无明显变化。检出DU、胃溃疡、胃癌的平均年龄1980年时分别为39.9岁、47.2岁和55.5岁,2004年分别为43.3岁、55.2岁和61.1岁,其平均年龄均呈上升趋势。Hp的平均检出率为43.54%,1995年以后呈下降趋势。结论DU、胃溃疡、胃癌的检出年龄呈上升趋势;DU、胃溃疡及Hp的检出率近年呈下降趋势,胃癌的检出率无明显变化。

The changes of gastric diseases during the past twenty five years

OBJECTIVES: To study the changes of duodenal ulcer, gastric ulcer, gastric cancer and Helicobacter pylori (Hp) infectious status, according to the clinical data of endoscopy in our hospital during the past 25 years. METHODS: The patients with duodenal ulcer, gastric ulcer and gastric cancer diagnosed by endoscopy and pathology had been selected, 104 987 general endoscope cases during the period from Jan. 1980 to Dec. 2004. The general cases were divided into 8 age groups as follows: 10-< 20 years old, 20-< 30 years old, 30-< 40 years old, 40-< 50 years old, 50-< 60 years old, 60-< 70 years old, 70-< 80 years old and > or = 80 years old. RESULTS: The average detected rate of duodenal ulcer, gastric ulcer, and gastric cancer are 13.03%, 4.19% and 1.68% respectively. The detected rate of gastric ulcer was decreased after 1996. The detected rate of duodenal ulcer was decreased after 1999. The gastric cancer detected rate fluctuate between 1.02% and 2.36%. The average ages of duodenal ulcer, gastric ulcer and gastric cancer are 41.8, 50.7 and 59.4 respectively. The tendency of average age shows ascendant. In all patients, the detected rate of Hp showed slightly descendent after 1999. CONCLUSIONS: The diagnostic age of duodenal ulcer, gastric ulcer and gastric cancer shows ascendant tendency; The detected rates of duodenal ulcer, gastric ulcer show descendent tendency; There is no apparent change in the detected rate of gastric cancer. The Hp detected rate shows descendent tendency slightly.
