Introduction: Diverticular disease is becoming more common in many developing countries as a result of change or modernisation of lifestyle and diet. Prevalence of diverticular disease is particularly common in the West and is reported to be increasing in the East. Right sided diverticular disease is more common in the East whereas in the West, left sided diverticular disease predominate. This study look at diverticular disease in Brunei Darussalam. Materials and Methods: All patients who had been undergone complete colonoscopy between 2011 and 2014 in a major tertiary referral centre were retrospectively identified through the Endoscopy Register and reviewed. Data on demography, indications for colonoscopy and findings of endoscopy were recorded. Records with complete data or incomplete colonoscopies were excluded. Results: The total number of colonoscopy done between the four years period was 2,763 (mean age 60.5 13.1 years old, male 55%), of which diverticular disease was detected in 480 giving a prevalence of 17.4%. The most common indications among patients with diverticular disease were surveillance/screening for colorectal neoplasms or cancers, evaluation of bleeding per rectum and abdominal complain (no significant difference compared to patients without diverticular disease). The distributions of diverticular were proximal only in 37.1%, distal only in 32.7% and pan-diverticular in 26.1%. Specifically by anatomical locations, diverticular disease were found in the rectum 3.3%, sigmoid colon 33.9%, descending colon 37.3%, splenic flexure 4.7%, transverse colon 15.7%, hepatic flexure 7.8%, ascending colon 54.3% and ceacum 15.3%. Other common endoscopic findings were haemorrhoids, polyps and non-specific colitis. Conclusion: Diverticular disease is common in out setting with almost one in five patient undergoing colonoscopy affected. In our study, right sided disease predominate but left sided disease was also common. However, all parts of the colon were affected.
