Filter by: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.
Use of Clearpath to facilitate successful completion of colonoscopy procedures with sub-optimal 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.
Colonoscopy is a procedure commonly performed to screen for colon cancer and to look for and remove colon polyps. It involves inserting a flexible tube, equipped with a video-camera at the tip, through the colon. The insertion process can be difficult in some patients, resulting in an uncomfortable and lengthy procedure.We postulate that raising the foot of the bed so that the stretcher forms a 15 degrees angle with the floor ("Trendelenburg position") may make the colonoscopy easier and more comfortable to the patient.
The purpose of this study is to determine whether fluid administration in patients undergoing colonoscopy should affect acid-base disorder in term of the strong ion differences.
