Filter by:Prior to colonoscopies, the colon is cleansed using a laxative. Golytely is approved by the FDA for this purpose. Another laxative, called MiraLax, is approved by the FDA to relieve constipation, but it is not approved specifically for preparation for a colonoscopy. Nonetheless, it is commonly used in clinical practice for this purpose, just as is Golytely. The purpose of this study is to compare Golytely and MiraLax in two ways: to see whether one is better tolerated by patients than the other and to see whether one more effectively cleanses the bowel than the other. The investigators' hypothesis is that these 2 bowel preparation methods are equally effective in bowel cleansing, but that patients prefer Miralax to Golytely.
Pico-Salax is an osmotic and stimulant bowel cleansing agent used prior to colonoscopy. It is unknown whether splitting the doses (i.e. taking the second dose the morning of the colonoscopy) results in a better bowel cleansing, as research with other agents suggests this may be the case. This study aims to assess whether splitting the dose of Pico-Salax results in a better bowel cleansing than traditional dosing.
The purpose of this study is to determine whether women who are offered screening colonoscopy will be more likely to schedule and complete this procedure if they are given the option of a woman endoscopist.
The purpose of this study is to see whether patients controlling their own sedation during colonoscopy are less likely to need help breathing than when an anesthesiologist controls the medicine, and whether we can predict when the need for help will occur. The pump used in the study is approved for clinical use by the FDA, as are the medicines used in the pump.
To compare the safety and efficacy of 2 different bowel cleansing preparations prior to colonoscopy in adult subjects.
To evaluate the safety and efficacy of BLI800 vs an FDA approved bowel preparation before colonoscopic examination in adult subjects.
We previously evidenced in both animal models and patients that a short duration ambulatory anesthesia impacts the circadian rest-activity biological rhythm, at least during the first 3 days. The light is the main, natural synchronisateur, of the biological cerebral clock, and is used as therapeutics in chronic disturbances of the circadian rest activity rhythm and of the sleep (Alzheimer disease for example). We would like to test for a simple and safe strategy to prevent such a long-lasting effect of anesthesia on biological clock:the increase of the light intensity at a still physiological level during the initial phase of recovery from anesthesia by using a particular artificial light of color spectrum similar to natural sun daylight.
A properly prepared colon is vital to the success of any colonoscopy. The purpose of this study is to determine which colon prep, MoviPrep or HalfLytely is the superior prepping agent.
Colonoscopy is the gold standard investigation for assessing the lining of the colon. Colon cleansing preparations are required to be taken prior to colonoscopy to provide effective visualisation and identification of any abnormalities and different types of colon cleansing preparations exist. Some colon cleansing preparations have been shown to cause visible changes in the lining of the bowel which may cause confusion and incorrect diagnoses to be made. This audit aims to assess the ability of different colon cleansing preparations to clear the colon of faeces. The tolerability of each will also be assessed, as will any changes in the lining of the bowel to assess if one type of colon preparation is more likely to cause visible changes than another.
Good colon cleansing is pivotal for achieving speedy and safe colonoscopic examination with high adenoma detection rate.Previous studies, including our previous RCT conducted in 2004 to 2005, have demonstrated that high yield rate can be achieved by on-the-day colon preparation with 2000 ml PEG-ELS. Poor patient compliance, however, is the main hurdle to complete ingestion of 2000 ml PEG-ELS not only for subjects with lower body weight but also for those with normal BMI or body weight.The main cause of poor patient compliance includes abdominal pain, bloating, nausea or vomiting during ingestion of cleansing fluid.Though diet restriction with low-fiber diet is always advised to every screen before colonoscopy, the extent of diet restriction is widely variable and thus influences the degree of colon cleansing. With commercialized low-residue diet (CLRD), diet restriction will be well controlled and variability of colon cleansing can be minimized such that guarantee a colonoscopy with good quality. In this RCT, we will compare the compliance of screen during colon cleansing using different protocol: namely 2000 ml PEG-ELS vs. 1500 ml plus low-residue diet.
