Overview
Patients with diabetes have less effective colonoscopy preparation when compared to nondiabetic patients. This leads to the possibility of missed polyps, longer procedural time and patient dissatisfaction. Furthermore, the peri-colonoscopy period has been associated with increased risk of hypoglycemic events given the required change in diet and possible changes in antihyperglycemic medication regime, though this area is not well studied. Studies have found that same day preparation for colonoscopy allowed for comparable bowel visualization to split dosing. Pairing this with a low fiber diet permitted the day prior to colonoscopy, the extent of changes to routine and diet within a patient with diabetes day for colonoscopy preparation is minimized and could reduce risk of side effects and hypoglycemia, while also ensuring adequate bowel preparation. This study tests the hypothesis that creating a diabetic specific protocol (permitting a low fibre diet the day prior to colonoscopy and using same day preparation) will result in fewer hypoglycemic events and more adequate quality preparation in comparison to a conventional 2L PEG split day preparation with dietary restrictions in patients with diabetes.
Interventions
