PEG-Asc Vs. SPMC for Bowel Preparation in Capsule-based Procedures

Participants receive a split-dose bowel preparation with 1 L polyethylene glycol plus ascorbic acid (PEG-Asc). The first dose is administered at 20:00 the evening before the procedure (500 mL PEG-Asc solution consumed over 1 hour, followed by 500 mL clear liquids). The second identical dose is taken at 06:00 on the day of the capsule procedure.

Participants receive sodium picosulfate with magnesium citrate (SPMC) in a split-dose regimen. The first sachet is dissolved in 150 mL water and followed by 1.5-2 L of clear fluids the evening before the procedure, and the second sachet is taken with the same fluid regimen on the morning of the procedure.
