Summary
The aim of this project is to study a new way of cleaning the bowel prior to colonoscopy. Current methods of cleaning the bowel are very effective but have some limitations. Bowel preparation currently involves drinking a large volume of salty tasting fluid which many patients do not like. An alternative method involves drinking a smaller volume of solution that can cause complications associated with dehydration and decreased salt levels within the body. In this study we will evaluate a new way of cleaning the bowel involving the use of a more gentle tablet laxative and diet restrictions in the three days before your colonoscopy. We are also interested in how you as the patient feel about this method of cleaning the bowel and we will ask you to fill in a questionnaire prior to your colonoscopy. The laxative we are using in this trial (Dulcolax) is freely available and works by stimulating the colon to pass bowel motions. It is a safe drug that is proven to be effective in helping empty the bowel. Dulcolax (bisacodyl) is approved by the Therapeutic Goods Administration of Australia to treat constipation and evacuation of the bowel. This study will be conducted at The Western Hospital Footscray. 200 people will be asked to participate in this trial.
