Background
A split dose (SPD) of purgative is the recommended bowel-preparation method for colonoscopy, although for colonoscopy scheduled for the afternoon, a same-day dose (SDD) of purgative is recommended. However, it has not been determined whether SPD or SDD is better in patients with gastrectomy who are at high risk of suboptimal bowel cleansing. We compared the bowel-cleansing efficacy of SPD and SDD regimens in patients with gastrectomy who underwent colonoscopy in the afternoon.
Methods
This was a prospective, randomized, assessor-blinded study. For the SDD group, polyethylene glycol (PEG) was ingested on the day of colonoscopy starting at 7 AM. In the SPD group, 2 L PEG was ingested at 9 PM the day before colonoscopy, and the remaining 2 L from 10 AM on the day of colonoscopy. Colonoscopy was performed from 1:30 PM. Before colonoscopy, the participants completed questionnaires asking about bowel-movement kinetics, adverse events, tolerability, overall satisfaction, and willingness to reuse the protocol. The bowel-cleansing efficacy was assessed using the Boston Bowel Preparation Scale.
Results
A total of 193 subjects were included (SDD, 95; SPD, 98). The rate of successful bowel cleansing was comparable between the two groups (SDD, 92.6% vs. SPD, 95.9%; P = 0.37). The incidence of adverse events (nausea, vomiting, bloating, abdominal pain, and dizziness/headache) was also comparable between the two groups. However, sleep disturbance was higher in the SPD group (SDD, 10.5% vs. SPD, 25.5%; P = 0.01). Tolerability did not differ between the SDD and SPD groups (satisfaction, P = 0.11; willingness to reuse, P = 0.29).
Conclusions
The bowel-cleansing efficacy, safety profile, and patient tolerability of SDD and SPD were comparable. Both SDD and SPD regimens are feasible bowel-preparation methods for patients with gastrectomy who undergo colonoscopy in the afternoon.
