Filter by:The objective of this study is to compare the safety, tolerance and efficacy of BLI800 (approved and investigational regimens) to an approved control preparation as bowel preparations prior to colonoscopy in adult patients, particularly including the elderly and those with renal and/or hepatic impairment.
Colonoscopy is an important procedure for diagnosing and treating diseases of the colon. In Canada, up to 13% all colonoscopies do not examine the full colon and are therefore incomplete. Incomplete colonoscopies happen for a number of reasons but are often due to twists and turns in the colon that make the colonoscopy difficult to perform and uncomfortable for the patient. This randomized study is being done to test a new colonoscopy system called the Scope Guide that shows an exact 3-dimensional picture of how the colonoscopy is positioned in the patient's abdomen. We hypothesize that the use of the Scope Guide for colonoscopy will improve measures of colonoscopy quality including rate of complete examination, patient comfort, polyp detection rate, insertion time, amount of sedation required, and need for abdominal compression.
In colorectal cancer screening era a huge burden of medical resources has been applied to surveillance. Although the adherence to post-polipectomy recommendations is a advocated as a mainstay for quality assurance colonoscopy programs, prospective data on appropriateness of surveillance are lacking. The aim of present study was to evaluate the percentage of subjects in which timing of surveillance colonoscopy in practice agrees with that recommended by guidelines and to identify factors associated to the appropriateness of surveillance.
Water immersion insertion and carbon dioxide (CO2)instead of room air insufflation as alternative colonoscopy techniques have been documented to decrease patient discomfort during and after the procedure. This prospective, randomized, single-center trial was designed to evaluate whether the combination of water immersion during insertion and CO2 insufflation during withdrawal (Water/CO2)for minimal sedation colonoscopy (2 mg of midazolam i.v.)is superior to the other colonoscopy methods (Water/Air, CO2/CO2, Air/Air).
The study was aimed to prospectively evaluate the acceptance rate of unsedated colonoscopy, in a setting where routine sedation for colonoscopy is standard practice and to characterize the subset of patients willing to try and potentially completing an unsedated procedure.
The aim of this prospective randomized controlled trial is to assess the efficacy of cap-attached colonoscopy to improve cecal intubation in comparison with regular colonoscopy for trainees.
Ultra-sound study to assess changes in intragastric volume after bowel preparation.
There was an only single operator study reporting dynamic position change during colonoscopy withdrawal significantly improved polyp and adenoma detection. So we designed a prospective, randomized multicenter study to verify the effect of dynamic position change in colonic adenoma detection. We think position change improve luminal distension and has the potential to improve adenoma detection rate.
Eligible subjects undergoing a colonoscopy will randomly receive either PICOPREP or polyethylene glycol 4000 electrolyte lavage solution before the procedure to evaluate its effectiveness, tolerability and safety.
The purpose of this study will be to determine if the temperature of water used during insertion of colonoscopy makes a difference in patient discomfort and sedation requirements. The hypothesis of this study is patients receiving screening colonoscopy utilizing the water insertion method with room temperature (cool) water will have similar pain scores and medication requirements compared to water insertion method using body temperature (warm) water.
