Filter by:Comparison of using the same-day 2 sachets picosulfate versus high volume PEG bowel preparation for afternoon colonoscopy Morning only same-day 2 sachets picosulfate may enhance patient tolerability and have similar bowel cleansing efficacy compared to standard method using high volume split-dose PEG. The investigators aimed to evaluate the efficacy and tolerability of bowel preparation protocols with same-day 2 sachets picosulfate compared to conventional high volume (4L) split-dose for afternoon colonoscopy.
Purpose of study: To evaluate the efficacy of PillCam Colon2 in subjects with an incomplete standard colonoscopy Study design: 4 centers, prospective, cohort study Number of subjects: 74 subjects Subject population: Patients that are indicated for colonoscopy, who are suspected or known to suffer from colonic diseases and had an incomplete standard colonoscopy Control group: None Procedure Duration: Approximately 10-12 hours Duration of Follow up: One week follow up Duration of study: 12 months Primary objectives: Evaluation of the efficacy of PillCam Colon2 to visualize the colon segment not reached by an incomplete standard colonoscopy Evaluation of distribution of excretion of capsules over time
During colonoscopy, the colonoscopist employs various maneuvers, including changing the patient's posture to left-lateral decubitus or supine, to achieve complete colonoscopic examination. Posture change has also been reported to increase the success rate of ileal intubation. However, there has been no randomized trial which has shown that a particular posture of the patient increases the success rate of ileoscopy. The present study will be carried out to determine the impact of the patient's posture (left lateral vs supine position) on success rate of ileal intubation.
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.
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.
The investigators hypothesize that NBI will have a high accuracy in predicting polyp histology real time during a colonoscopy by visualization of the surface mucosal and vascular patterns. Aim#1: To determine the sensitivity, specificity and accuracy of NBI and standard white light colonoscopy for predicting polyp histology by evaluating the surface mucosal and vascular patterns during colonoscopy. Aim#2: To determine the inter-observer agreement between investigators for the recognition of various polyp patterns.
The quality of colon cleansing has a major impact on efficiency and cost of colonoscopy. A hand-out was made to instruct and motivate patients to adequately clean the bowel before colonoscopy. The aim of the study is to compare adequacy of bowel cleansing in hospitalized patients receiving the hand-out or not on the day before colonoscopy.
