The aim of the study is to study the caecal intubation rate of a prototype ultra-thin colonoscope compared to a standard colonoscope and to study usefulness of this new colonoscope as a rescue instrument for failed initial colonoscopy with a standard colonoscope and to study the patient satisfaction scores using a validated endoscopy GHAA-9 for a new prototype colonoscope as compared to a standard colonoscope.
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.

Patients with a prior incomplete colonoscopy will be enrolled in this study. Patients will be randomized to either an initial repeat attempt with a standard colonoscope or the single ballo...
The study aims to compare the results between a standard colonoscopy to a colonoscopy with an attachment on the distal end of the colonoscope.
This is a study to compare two different, but normally, used methods of colonoscopy in patients undergoing colonoscopy without sedation. There will be two arms in this study: WE (water exc...
The EndoCuff is novel flexible cuff that can be attached to the distal tip of the colonoscope and helps to flatten large mucosal folds during withdrawal. The study hypothesis is that the ...
The purpose of this study is to evaluate a handheld Colonoscopy Force Monitor(CFM™), a push-pull force and torque measuring device, that grips the shaft of the colonoscope and wirelessly...
The most commonly missed polyps in colonoscopy are those located behind haustral folds. The G-EYE system is a standard colonoscope consisting of re-processable balloon at its distal tip. The G-E...
Split dose bowel preparations (SDP) have superior outcomes for colonoscopy as compared to evening before regimens. However, the association of the actual volume of the SDP to colonoscopy outcome measu...
Background Cecal intubation rate represents a key procedural quality parameter in diagnostic colonoscopy. However, even experienced investigators report 10 % of all colonoscopies to be difficult and...
Although colonoscopy is the criterion standard for detection of colorectal adenomas, some adenomas are missed. Full-spectrum endoscopy (FUSE) allows for observation with a 330° angle of view, which i...
Previous research has assessed anxiety around colonoscopy procedures, but has not considered anxiety related to different aspects related to the colonoscopy process.
Endoscopic examination, therapy or surgery of the luminal surface of the colon.
Agents that are used to evacuate the bowels to eliminate ingested NOXAE or to prepare for COLONOSCOPY.
A condition characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. This syndrome was first described in 1980 by Read and associates. Subtypes include COLLAGENOUS COLITIS and LYMPHOCYTIC COLITIS. Both have similar clinical symptoms and are distinguishable only by histology.
A subtype of MICROSCOPIC COLITIS, characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. Microscopic examination of biopsy samples taken from the COLON show larger-than-normal band of subepithelial COLLAGEN.
A subtype of MICROSCOPIC COLITIS, characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. Microscopic examination of biopsy samples taken from the COLON show infiltration of LYMPHOCYTES in the superficial EPITHELIUM and the underlying connective tissue (lamina propria).
Pain is defined by the International Association for the Study of Pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage”. Some illnesses can be excruci...
