探讨延边地区朝鲜族消化性溃疡(PU)的发病特点。方法 内镜检出的4842例PU，分成朝鲜族组和汉族组进行对比分析。结果 胃溃疡(GU)检出率朝鲜族显著高于汉族而十二指肠溃疡(DU)检出率则相反；朝鲜族GU检出率显著高于DU检出率而汉族则相反；复合性溃疡(CU)检出率春季朝鲜族显著高于汉语而秋季则相反；PU检出率冬春两季朝鲜族均显著高于汉族。PU幽门螺杆菌(HP)阳性率朝鲜族显著高于汉族，DU患者HP阳性率显著高于GU患者。胃窦、胃体和球部前壁溃疡发生率朝鲜族显著高于汉族，而胃角、幽门管和球部大弯侧溃疡发生率则相反。各类溃疡发生率40岁组朝鲜族显著高于汉族，而≤40岁则相反，各类溃疡平均发病年龄朝鲜族均显著大于汉族。两民族GU均以胃窦最多，而DU均以球部前壁最多，两民族各类溃疡发病均以秋季最高。结论 延边地区朝鲜族PU在检出率、检出季节、发病部位、年龄及HP感染等方面均有自己的发病特点。%Objective To study the characteristics of peptic ulcer (PU) ofkorean nationality(KN).Method The 4842 cases of PU were detected by gastroscopic technique from Jan 1985 to Apr 1999.The patients were divided into Korean nationality(KN,n＝3124) and Han nationality(NH,n＝1718) groups,the difference of between two groups was compared and analyzed.Results The morbidity of gastric ulcer C(GU) in KN group was obviously higher than that of HN group,however,the morbidity of duodenal ulcer(DU) was lower in KN group.Morbidity of GU was signifcantly higher than those of DU in KN group.In contrary to KN group,it was lower in HN group.The moraibity of composite ulcer(CU) in KN group was significantly higher than those of HN group in the spring,but in the autumn,the CU morbidity of HN group was higher.PU morbidity of KN group in the spring and winter were markedly higher than those of HN group.The helicobacter pylori(HP) infective rate of the patients with PU in KN group was significantly higher than those of HN group.HP positive rate of the patients with DU was obviously higher than that of the patients with GU.The morbidity of ulcer in KN group was significantly higher than that in HN group at gastric antrum,gastric body,anterior wall of duodenal bulb respectively,but the ulcer morbidity of gastric angle,pyloric canal,greater curvative of duodenal bulb were higher in HN group than that in KN group.The morbidity of all types peptic ulcer in KN group was remarkable higher than that of HN group in age over forty.In constrast,under forty-age-old(or equal to forty),the PU incidence of those anatomical situs of KN group was lower than that of HN group.The average phathogenic attack age of all type ulcer in KN group were significantly higher than that in HN group.The morbidity of ulcer of gastric antrum and anterior wall of duodenal bulb were most in two nationality groups,the autumn was the most season in two nationality groups.Conclusions PU of KN has own characteristics in detectable rate,attack season,pathogenetic situs,age of PU attack as well as HP infection etc.
