Active Comparator: Standard Colonoscopy
Colonoscopy with standard instrument
Procedure: Standard Colonoscopy
Standard colonoscopy will be used during colonoscopy
Experimental: Ultra-thin colonoscopy
New prototype scope
Procedure: Ultra-thin colonoscopy
Ultra-thin colonoscope will be used during colonoscopy
Colonoscopy is a common endoscopic procedure, widely used for the investigation of lower gastrointestinal tract diseases manifesting as altered bowel habit, per rectal bleeding and abdominal pain. It is used to diagnose colonic polyps, colorectal cancer and inflammatory bowel disease to name a few examples.
Colorectal cancer screening has been shown to decrease colorectal cancer. Despite this the uptake by the general population is suboptimal.
A new prototype colonoscope from Olympus with an additional distal bending section was designed. The investigators hypothesize that its performance characteristics will be similar to a standard colonoscope with patient tolerability.
This randomised control trial aims to invite patients attending their first outpatient colonoscopy and who are able to provide informed consent.(so they have had no prior experience) to assess the completion rate, patient and endoscopist satisfaction.
Patients with prior colorectal surgery or previous colonoscopy were excluded.
