the efficacy and tolerability of a low-volume (2 L) PEG regimen for colonoscopy compared to single (4 L) or split-dose (2 L + 2 L) treatments are not different.
In-hospital patients were randomly assigned to one of three groups: group 1 single dose (PEG-3350; PEG-4 L the day previous of the study, starting at 17:00 and finishing at 21:00 h); group 2: split-dose (PEG-3350; 2 L the day before 17:00-19:00 h and 2 L same day of the procedure 06:00-08:00 am); group 3: low-volume 2 L PEG-solution (same day of the procedure 06:00-08:00 am).
The quality of colonic preparation was assessed by the Boston bowel preparation scale (13); tolerability (nausea, vomiting, and abdominal pain), compliance, sleep disturbance and adverse effects in group 3 were compared with those in groups 1 and 2. The time since the last dose of bowel-preparation agent, the time since the last solid food was consumed, the approximate amount of bowel preparation taken (0%, 25%, 75%, or 100%), and the start time of the colonoscopy were recorded.
Satisfactory colon preparation was considered when scores of the Boston bowel preparation scale were 2/3; otherwise, the procedure was considered unsatisfactory preparation.
