A Multicenter Single-blind Comparison Between Standard and Individualized Approach in Bowel Preparation Before Colonoscopy

A Comparison of Bowel Prep Quality and Patient Satisfaction in Outpatients Undergoing Colonoscopy Preparation With Either a Standard Bowel Preparation or an Individualized Approach Using Sodium Picosulphatge/Magnesium Citrate or 4L Polyethylene Glycol Preparation Regimens

This study aims to compare a standard approach to bowel preparation for colonoscopy (using sodium picosulphate/magnesium citrate or 4lPEG) to an individualized approach where patients are assigned a specific regimen of either sodium picosulphate/magnesium citrate or 4lPEG depending on patient-related factors. The study aims to compare patient-related outcomes such as comfort levels during bowel cleansing and physician-related outcomes such as bowel prep quality in the two study groups.

Inclusion Criteria:

• all patients > 18 years of age undergoing elective colonoscopy on an outpatient basis
