7,543 double-contrast barium enema studied for the presence of diverticula which were classified into right-sided, left-sided and bilateral types, and the relationship of the frequency (detection rate) and numbers of diverticula to age were examined for the earlier (1982-87) and later (1988-92) periods. Diverticular disease was found in 22.2% of male and 15.5% of female examinees. The right-sided type predominated among the subjects. Frequency distribution by age of the bilateral type was similar to that of the left-sided type. Bilateral diverticular disease increased in frequency with advancing years in the sixth and seventh decade, the right-sided type increased in middle-aged subjects, and the left-sided type did not. The bilateral type was composed of diverticula in the right colon, where numbers were greater than in the pure right-sided type, but remained unchanged with increasing age, and diverticula in the left colon, where numbers were similar to the pure left-sided type, but did not increase with age. Increase in the prevalence of bilateral and not pure left-sided form has contributed to the recent increase in diverticula in the left colon among the Japanese, and might have been preceded by an increase in the right-sided type.
对7543例进行了双重对比钡灌肠检查，以确定憩室的存在，这些憩室被分为右侧、左侧和双侧类型，并对早期（1982 - 1987年）和后期（1988 - 1992年）憩室的发生率（检出率）及数量与年龄的关系进行了研究。在男性受检者中发现憩室病的比例为22.2%，女性为15.5%。右侧类型在受检者中占主导。双侧类型按年龄的频率分布与左侧类型相似。双侧憩室病在第六和第七个十年中随年龄增长而增加，右侧类型在中年受试者中增加，而左侧类型则没有。双侧类型由右结肠憩室和左结肠憩室组成，右结肠憩室数量比单纯右侧类型多，但不随年龄增长而变化，左结肠憩室数量与单纯左侧类型相似，但不随年龄增加。双侧而非单纯左侧形式患病率的增加导致了近期日本人群左结肠憩室数量的增加，且可能在右侧类型增加之前就已出现。
