Nearly all of the patients receiving P/MC were able to consume the split-dose of P/MC the day before (100%)
and the day of the colonoscopy (99.7%). Complete colonoscopy (ie, cecal intubation) was achieved for the majority of patients (99.3%). The small number of incomplete colonoscopies resulted from the quality of preparation in 1 patient and a structural abnormality that resulted in blocked visualization at the hepatic flexure in 1 patient. Compared with P/MC, 91.4% of patients receiving 2L PEG-3350 and bisacodyl tablets were able to ingest all of the bowel preparation. Complete colonoscopy was achieved for the majority of patients (98.7%). Incomplete colonoscopies in the 2L PEG-3350 and bisacodyl tablets treatment arm resulted from the quality of preparation in 3 patients and a redundant rectosigmoid colon in 1 patient
