Abstract
AIM: To analyze the epidemiological features of colorectal diverticulum (CRD) in China. METHODS: We retrospectively analyzed CRD patients in 8 tertiary hospitals located in 5 regions of China from 2000 to 2016. The detection rates, number and distribution, demographic information, concomitant disorders, and their associations were investigated. RESULTS: Of 3,446,118 cases, 7,964 (2.3%) were CRD with a mean age of 56 years (11-92 years). The detection rate increased yearly and with increasing age. Males had a higher detection rate than females (3.0 vs. 1.47%, p < 0.01) and 1.8-times higher increase rate. The detection rate increased with age; however, females of > 60 years had a 2.8-times increasing rate than males. CRD occurred most frequently in the right-side colon, followed by rectum. Multiple diverticula were common in males and increased with age, with a 3-times higher increase rate than single lesion. Single-segment CRD occurred more frequently in males than in females (80.1 vs. 76.4%, p < 0.01). Concurred colon polyps were seen in 51.05% cases. CONCLUSION: CRD detection rates increased annually and with age, particularly in senior females in China. Multiple diverticula were common in males and increased with age. CRD was predominant in the right-side colon. Polyps are the most common comorbidity associated with CRD.
