Left-sided diverticular disease (LDD) is associated with reduced dietary intake, whereas right-sided diverticular disease (RDD) is more common amongst Oriental populations. We aimed to determine whether the prevalence, site and distribution of diverticular disease in our Oriental population has changed over the past two decades.
A total of 1663 barium enema studies performed between January 2001 and August 2002 were reviewed retrospectively. The site of disease was correlated with age, gender and ethnicity of the patient.
Forty-five per cent of patients in the study population had diverticular disease. Older patients were more likely to have LDD, whereas the Chinese ethnic group was more likely to have RDD. Right-sided diverticular disease peaks at in the sixth decade, while for LDD this occurred in the seventh and eighth decades. Right-sided diverticular disease was more common in all age groups overall. When compared with two barium enema studies carried out in Singapore two decades earlier, there was a statistically significant increase in the incidence of RDD and LDD.
There is a positive association of RDD and LDD with Chinese race and increasing age. There is an increasing incidence of both LDD and RDD compared with two decades previously.
左侧憩室病（LDD）与饮食摄入减少有关，而右侧憩室病（RDD）在东方人群中更为常见。我们旨在确定在过去的二十年中，我们东方人群中憩室病的患病率、部位和分布是否发生了变化。
回顾性分析了 2001 年 1 月至 2002 年 8 月期间进行的 1663 例钡灌肠研究。将疾病部位与患者的年龄、性别和种族相关联。
研究人群中 45%的患者患有憩室病。老年患者更有可能患有 LDD，而华裔患者更有可能患有 RDD。右侧憩室病在第六个十年达到高峰，而 LDD 则在第七和第八个十年达到高峰。右侧憩室病在所有年龄段均更为常见。与 20 年前在新加坡进行的两项钡灌肠研究相比，RDD 和 LDD 的发病率有统计学意义上的显著增加。
RDD 和 LDD 与华裔和年龄增长呈正相关。与 20 年前相比，LDD 和 RDD 的发病率均有所增加。
