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

Interventions

DRUGPEG-ascorbate 2L

Subjects will be asked to proceed to colonic cleansing with the interventional agents as per summary of product characteristics and specific instructions from members of the research team. Participants will be required to be on a low residue diet for 4 days before the procedure. The preparation will begin at 9:00 pm on the evening before the colonoscopy is scheduled. Participants will take 2 sachets (labelled A and B) of the investigational product and take their contents diluted in 1 liter of water. Two other sachets, also labelled A and B, will be taken diluted in 1 liter of water 4 to 5 hours before the procedure. Fasting will be required from 2 hours after the investigational product has been taken.

DRUGPEG 4L

Subjects will be asked to proceed to colonic cleansing with the interventional agents as per summary of product characteristics and specific instructions from members of the research team. Participants will be required to be on a low residue diet for 4 days before the procedure. The preparation will begin at 9:00 pm on the evening before the colonoscopy is scheduled. Participants will take 8 sachets of the investigational product and take their contents diluted in 2 liters of water. Eight other sachets, also diluted in 2 liters of water will be taken 4 to 5 hours before the procedure. Fasting will be required from 2 hours after the investigational product has been taken.
