Filter by:This study assesses the benefits of continuous intravenous lidocaine administration during sedation for colonoscopy. Sedation will consist of propofol infusion titrated to provide adequate working conditions to the gastroenterologist. Patients will be randomly allocated into two groups: lidocaine infusion (bolus of 1.5 mg/kg followed by a continuous infusion of 4 mg/kg/h) or the same volume of placebo (normal saline)
This prospective, randomize, controlled trial will compared cap-assisted water exchange with water exchange in patients undergoing sedated colonoscopy. Investigators test the hypothesis that that cap-assisted water exchange is more efficient and causes a shorter insertion time.
About 30% of patients were reported to suffer inadequate bowel preparation.
The purpose of this study is to compare the effect of physician education about evidence based practices for colonoscopy alone, versus physician education plus a multi-component staff implementation strategy to improve adequacy of bowel preparation. Additionally the investigators will examine implementation factors that influence adoption of the evidence based practices.
This study is an open, prospective, comparative diagnostic studies aimed at improving the colonoscopy results, by optimizing the way of preparation for endoscopy
Better patient education prior to colonoscopy improves adherence to instructions for bowel preparation and leads to cleaner colons. The hypothesis of this trial is that computer assisted instruction (CAI) using video and 3D animations can maximize the effectiveness of nurse counselling and consequently improves bowel cleanliness. Furthermore, CAI will positively influence the patient experience. Adults referred for colonoscopy were included in a Dutch large volume endoscopy unit. Exclusion criteria were illiteracy in Dutch and audiovisual handicaps. Patients were prospectively divided into two groups, one receiving nurse counselling and one receiving CAI and a nurse contact before colonoscopy. The main outcome, cleanliness of the colon during examination, was measured with the Ottawa Bowel Preparation Scale (OBPS) and the Boston Bowel Preparation Scale (BBPS). Patient comfort and anxiety were assessed at multiple time points: directly after the instruction and one hour before colonoscopy. Comfort was rescored 2 hours after colonoscopy. We also tested knowledge and comprehension one hour before colonoscopy. Statistical analyses included Mann-Whitney.
Comparison of quality of preparation of colonoscopy in patients taking same day 4L preparation vs. 4 L split dose preparation in patients scheduled for an afternoon colonoscopy procedure.
Carbon dioxide insufflation during colonoscopy significantly reduces discomfort (pain, bloating and flatulence) after the procedure. So far, it has not been studied in inflammatory bowel disease patients. The study was designed to evaluate discomfort after the carbon dioxide insufflation colonoscopy in comparison to standard air insufflation colonoscopy.
A prospective, double-blind, randomized, placebo and active controlled, multi-center, parallel group study comparing remimazolam to placebo, with an additional open-label arm for midazolam, in American Society of Anesthesiologists (ASA) Grade III and IV patients (ASA status evaluated by an anesthesiologist not otherwise involved in the study) undergoing a colonoscopy for diagnostic or therapeutic reasons.
In this study, Dutch gastroenterologists who are certified for performing colonoscopies on FIT-positive patients in the Dutch population screening program are trained in optical diagnosis with validated methods. After this training, an ex- and in-vivo test phase leads to "accreditation" and endoscopists will be observed in their optical diagnosis for 1 year. During this year, half of the endoscopists will be randomized towards 3-monthly feedback and the other half will receive feedback on their results after 1 year. The endoscopic prediction of endoscopists on polyp histology will be compared to histopathological outcome.
