Overview
Brief Summary
This trial will compare the tolerance to 2 different methods for colon cleansing before colonoscopy in diabetic patients.
Detailed Description
Consecutive diabetic patients undergoing an ambulatory colonoscopy at the participating sites will be randomized to 2 different methods of colon cleansing before the procedure. Both will be based on the oral ingestion of a fluid solution (half of it on the evening before the procedure is planned and the rest on the morning of the same day), and the main difference between them will be the volume of fluid that will be ingested in each case. Analogic visual scales and standardized questionnaires on various aspects that may influence the degree of satisfaction about the preparation will be answered by the participants and collected before the colonoscopy. The endoscopist, blinded to the preparation method, will grade the adequacy of the preparation. Adverse events will be recorded up to 1 month after the procedure

Outcomes
Primary Outcomes
Tolerability of the bowel preparation (analogue visual scale)
Time Frame: 6 hours after finishing bowel preparation
Each participant will rate his/her experience in an analogue visual scale.
Secondary Outcomes
- Adverse events(30 days after the colonoscopy)
- Abdominal pain, nausea and bloating (analogue visual scale)(6 hours after finishing bowel preparation)
- Efficacy of the bowel preparation (Boston Bowel Preparation Scale (BBPS)(10 minutes after the colonoscopy)
- Acceptability of the preparation (interference with work, leisure activities or sleep questionnaire)(6 hours after finishing bowel preparation)
- Adherence to the planned bowel cleansing method (questionnaire)(6 hours after finishing bowel preparation)
- Ease of consumption and taste of the laxative (analogue visual scale)(6 hours after finishing bowel preparation)
