无症状上消化道憩室的增龄性改变

Correlations of the incidence of asymptomatic diverticula with the age increasing in patients

目的回顾性分析无症状上消化道憩室的增龄性改变。方法选择2003年1～12月无消化道症状的上消化道造影体检的老年前期及老年人645例,年龄50～79岁,按年龄分为50～59岁(206例)、60～69岁(201例)、70～79(238例)组,分别对各年龄组发生上消化道憩室的例数、部位和个数进行分析,比较无症状上消化道憩室的增龄性变化。结果各年龄组发生消化道憩室的例数随增龄而增加,分别为37例(18.0%)、56例(27.9%)、68例(28.6%),后两组与50～59岁组比较,差异有统计学意义(均为P<0.05);各年龄组食道、胃和十二指肠发生憩室个数随增龄而增多,70～79岁组与50～59、60～69岁组比较,差异有统计学意义(均为P<0.05)。上消化道憩室以十二指肠降部居多,161例中有104例(64.6%),各组十二指肠降部憩室发生的构成比分别为11.7%(24例)、21.4%(43例)、15.5%(37例)。结论老年人消化道憩室是一种退行性改变,随增龄其检出率和憩室个数增加,且以十二指肠降部憩室居多。

Objective To study the correlation of the incidence of diverticula in the upper gastrointestinal tract and the age increasing among the people without any symptom in digestive system. Methods Six hundred and fcurty-five elderly and pre-elderly people（age from 50 to 79 years）with asymptom diverticula were divided into 3 groups basing on their age：50 to 59 years group （206 cases）, 60 to 69 years group（201cases） and 70 to 79 years group（238 cases）. Difference in numbers and locations of the diverticula in each group were analysed. Results The patients with diverticula in each group were found to be 37 cases（18.0%） .56 cases（27.9%）and 68 cases（28.6%）, respectively, showing that among these 3 groups, the incidence of diverticula increased with ages （P〈0.05）. The diverticula in 104 cases（64.6%） of 161 cases were located in the descending part of duodenum, which were more than those in esophagus, stomach and small intestine. In each group, the incidence of diverticulas in the descending part of duodenum was 24 cases（11.7 %）,43 cases（21.4%） and 37 cases（ 15.5% ）, respectively. Conclusions Diverticulosis of elderly people is a degenerative disease, in which the incidence and the number of diverticula were increased with ages. The descending part of duodenum is the most common location of diverticula.
