Constipation is not associated with diverticular disease – Analysis of 976 patients

Abstract

BackgroundIn the light of controversial data in the literature, the present study was designed to evaluate potential associations between colonic diverticular disease, constipation and quality of life. DesignWe prospectively enrolled 976 consecutive patients, who participated in the nationwide colorectal cancer screening program in four medical centers between 2008 and 2009. All patients underwent full colonoscopy and completed a standardized questionnaire. The severity of constipation was assessed by the validated Wexner constipation score. Quality of Life (QOL) was evaluated by the SF-12 health score. ResultsThe median age was 62 years (range 22–90) and the male to female ratio was 1:1. Colonic diverticular disease was found in 290 participants (30%). Age, body mass index and diabetes mellitus were significantly associated with the presence of diverticular disease (p < 0.0001, p = 0.0007 and p = 0.0178).The median constipation score in patients with diverticular disease was 3 (range 0–18), and comparable to patients without diverticula (p = 0.1073). The physical component summary of the SF-12 was significantly reduced in patients with diverticular disease (p = 0.0038). ConclusionThis large population based study revealed no association between colonic diverticular disease and constipation. Notably, the presence of diverticular disease significantly impacts quality of life.
