Filter by:Several factors are considered as the key indicators of quality colonoscopy, including endoscopist experience, withdrawal time, and quality of bowel preparation (BP). A number of laxatives are currently used as BP, and these are mainly based on PEG agents that differ for the volume and the addition of adjuvants. Several trials have demonstrated the efficacy and safety of low volume 2L-PEG based regimens compared with high volume PEG regimens and non-PEG agents. However, for low-volume 1L-PEG plus ascorbate (1L-PEG-Asc) only the data from registration trials are available, and none of these have been performed in an "open access" colonoscopy booking system. The aim of our study was to evaluate the safety and tolerability of 1L-PEG-Asc compared to 2L-PEG plus ascorbate (2L-PEG-Asc) in an "open access" booking system.
Adequate bowel preparation is critical for successful colonoscopy and a large volume of PEG was required for bowel preparation in patients undergoing colonoscopy. The investigators conducted a a prospective, randomized, controlled study to compare low dose of oral magnesium sulfate solution with high dose PEG. The investigators found that patients who took low dose of oral magnesium sulfate solution had similar bowel preparation quality to patients who took PEG,but accompanied with fewer adverse events and better tolerance.
In order to analyze the effectiveness and patient tolerance of the two bowel preparation regimens, the investigators will compare prepackaged semisolid nutritional formulations and restricted diet. The aim was to demonstrate that prepackaged semisolid nutritional formulations is not inferior in overall quality of intestinal preparation to restricted diet in subjects undergoing colonoscopy.
The diagnostic accuracy of colonoscopy depends on the quality of bowel preparation, which is a critical element associated with the diagnostic yield, difficulty, time required, and the completeness of colonoscopy. The non-digestive physicians seemed to have a lower quality of bowel preparation compare to the digestive physicians. Therefore, investigators planned to evaluate the risk factors for suboptimal intestinal preparation in outpatients from the perspective of digestive doctors and non-digestive.
The diagnostic accuracy and safety of colonoscopy highly depends on the quality of the pre-procedural bowel preparation. A past history of poor bowel preparation is the most important risk factor of inadequate bowel cleansing at the next colonoscopy. This study aims to evaluate if an adequate level of bowel cleansing can be achieved with the Pure-Vu System in patients with previous poor bowel preparation, in a single arm international multicenter feasibility study.
background:The use of enhanced instruction can improve the efficiency of education for bowel preparation regimens. Researchers hypothesized that face-to-face instruction and personalized intervention for inpatient could improve successful bowel preparation rate and patient's compliance with regimens. Methods:This was an endoscopist-blind,randomized controlled trial. 320inpatients were randomized 1:1 in one of the two study groups. The intervention group received face-to-face instruction and personalized intervention for bowel preparation protocol, while control group received the standard bowel preparation protocol. Patients'demographics, bowel preparation quality, colonoscopy completion and attendance were recorded. Logistic regression was performed to identify predictors of bowel preparation failure.
A deep learning based system to calculate the proportion of Boston Bowel Prep Scale (BBPS) score of 0-1 during withdrawal phase has been constructed previously. This multi-center study is going to perform a prospective observational study to validate the threshold of the adequate proportion.
Polyethylene glycol (PEG) is one of the most common laxatives used in colonoscopy. However, 5 - 15% of patients can not complete the preparation due to its poor taste and large volume. So this study is aimed to explore the effect of antiemetics on abdominal discomforts associated with PEG.
Electronic colonoscopy plays an important role in the diagnosis and follow-up of intestinal diseases in children.
The primary objective of this study is to compare the efficacy of administration routine bowel cleansing medication (Bowklean) for the Bowel Preparation at Different Times Prior Colonoscopy in the morning or in the afternoon.
