Brief summary
Colonoscopy offers both a diagnostic and therapeutic tool in the early detection of colorectal cancer. The quality of bowel preparation significantly impacts the success of colonoscopy. Optimal bowel preparation leads to decreased procedure time and increased polyp detection rate. A suboptimal bowel preparation can result in small or flat lesions being missed, shortened surveillance times and need for multiple procedures. In addition, it results in increased technical difficulty and likelihood of complications. Factors shown to affect quality of bowel preparation include the type of solution chosen, administration or timing and the patient’s hydration status and diet. The ambient temperature can impact daily activities and as such we propose that this will also have an effect on the quality of bowel preparation. This trial performed secondary analysis of existing data collected as part of a previous prospective trial investigating the tolerability of bowel preparation in inflammatory bowel disease patients compared to the general population. Ambient temperature was recorded as the minimum and maximum temperature as documented by the local Bureau of Meteorology weather observation station on the day prior to the scheduled colonoscopy.
Interventions
This trial is a secondary analysis of existing data collected as part of a previous prospective trial investigating the efficacy and tolerability of different bowel preparations in both inflammatory bowel disease patients and the general population.
In the original trial, patients were randomised to two different types of bowel preparation (Moviprep or Prep Kit C).
