Outcome Measures
Primary Outcomes (8)
Degree of gut cleansing
Degree of gut cleansing in each of five predefined gut segments (rectum, sigmoid colon, descending colon, transverse colon, ascending colon) rated on a 5-level verbal rating scale (VRS) ranging from 4 (very good) to 0 (very bad) by 1. the physician performing the endoscopic procedure and 2. by an independent reviewer on the basis of video tapes registered during colonoscopy.
Day 0 during colonoscopy
Overall quality of colonic cleansing
Overall quality of colonic cleansing as rated on a 3-level VRS with ranks: A = very good or good colon cleansing in all five gut segments, B = at least one colon segment with moderate or bad cleansing result, C = very bad cleansing result in at least one colon segment.
Day 0 during colonoscopy
Physicians overall judgement of colon preparation
Physicians overall judgement of colon preparation as assessed on a 5-level VRS ranging from very good to very bad.
Day 0 during colonoscopy
Volume of fluid aspirated (ml)
Volume of fluid aspirated from intestinal lumen during colonoscopy.
Day 0 during colonoscopy
Stool and urine weight (g)
Weight of stools and urine sampled from the beginning of gut preparation until the start of the endoscopic procedure.
Day -1 and Day 0 prior to colonoscopy.
Clear effluent
Number of patients in whom a clear effluent (containing no residual faecal material) was obtained.
Day -1 and Day 0 prior to colonoscopy.
Patient satisfaction - convenience

Study Arms (1)
NRL994 low dose bowel prep (LDBP)
EXPERIMENTALPatients given two doses of NRL994, one on the evening before and one on the morning of their scheduled colonoscopy. Degree of gut cleansing was rated by the colonoscopist and an independent reviewer. Volume of fluid aspirated during colonoscopy and weight of stools/volume of urine from start of cleansing to start of colonoscopy were also measured. Number of patients who reached clear effluent evaluated.
Interventions
In the afternoon/evening before colonoscopy: 1 litre solution plus 0.5 litre clear fluid. Day of colonoscopy: 1 litre solution plus at least up to 1 litre clear liquid.
