Filter by:The purpose of this study is to assess the impact of multilevel factors on the quality of screening colonoscopy, reflected mainly by adenoma detection rate (ADR).
Colonoscopy patients will be fitted with a virtual reality head-mounted display, and virtual experiences will be initiated prior to colonoscope insertion. Colonoscopy will be initiated without standard sedatives and narcotics. The colonoscopy will proceed with the subject using virtual reality distraction instead of pharmacological sedation for as long as s/he would like. Standard sedatives and narcotics will be administered upon participant request at any time during the procedure. Questionnaires will be administered to the subject and the endoscopist after each procedure to assess the acceptability of use of virtual reality in the colonoscopy setting.
For recent years, patients are more likely to accept sedation during endoscopic examination due to better quality and experience. Modest anesthetic state for different kind of procedure is important, but it is also not easy to maintain in the same state all the time. Thus, to prevent awareness during the procedure, monitoring the brain state is an important issue. Traditionally, anesthesiologists assess patients' brain state from heart rate, blood pressure and muscle tone. All these vital signs are indirect hint for the real brain state. Thus, electroencephalogram(EEG) was considered to be potential tool to directly monitor our brain during anesthesia. In 1937, EEG study was started in anesthetic patients. Until 1994, Bispectral Index, the first commercialized processed EEG monitor, was published for intra-operative brain state assessment. To perform EEG study on a surgical patient is not easy due to the complex circuits and lots of interrupts during the procedure. This might be the reason why most of the EEG studies under anesthesia are collecting from healthy volunteers. It takes longer preparation, better team cooperation, and support from hospital to start this study in endoscopy room. The investigators would like to start from a preliminary study, 5 patients in each groups, and collect the EEG during peri-endoscopic period. The sedation steps follow the routine protocol of our practice. Flumazenil and placebo are given to the groups separately on the end of the examination. From this study, further understanding of human brain during sedation especially in such short periods is expected. And furthermore, to give safer and more comfortable anesthetic experience for the patients.
Bowel preparation is closely lined to the quality of colonoscopy, inadequate bowel preparation (IBP) could lead to higher miss rate of adenomas, patients' discomfort and higher health expense. For the patients with possible IBP before the examination, it may be better to cancel the colonoscopy and repeat bowel preparation through modified or enhanced strategies. This study aimed to externally validate the efficiency of a procedure-based model in predicting inadequate bowel preparation
This prospective randomized trial will be conducted in all patients undergoing elective colonoscopies from February 2020 to August 2020 in Dowites Operation Theater Endoscopy suite by surgical unit III, Civil Hospital Karachi. Patient will be select randomly based on inclusion criteria. Patients will be advised to take 90ml of sodium phosphate in 800ml solvent ( zero calorie soft drink and water). Patients will be nil per oral from midnight aside from clear liquids. Serum electrolytes, urea, creatinine will be measured after and before bowel preparation. Bowel preparation will be assessed by consultant during endoscopy. Questionnaire will be filled by PI for palatability, tolerance of solution, adverse effects, and willingness to repeat the preparation.
Background and aims: Inpatients are at high risk for inadequate colon cleansing. Experts recommend 4L-polyethylene-glycol (PEG) solution because of its effectiveness and safety profile. A higher colon cleansing adequacy rate for a hyperosmolar 1L-PEG plus ascorbate prep has been recently reported in an observational study among more than 1,000 inpatients. Thus, the present study is aimed at determining whether 1L-PEG outperforms 4L-PEG among inpatients, through a propensity score-matching between the two groups in order to correct for confounders.
High-quality colonoscopy is considered the gold standard for the detection and prevention of colorectal cancer, and its efficacy is predicated on optimal colon cleansing.However, about 18%-35% of patients were still reported to suffer inadequate bowel preparation. Although several predictive models exist, the current guideline indicates that there is insufficient evidence to recommend the use of a predictive model for clinical practice.
The study examines the impact of music during colonoscopy on sympathetic - autonomic nervous system, whose activity is operationalized by biopotentials signals. The music is chosen by the patients themselves. The Null hypothesis: The comparison of the sympathetic - autonomic nervous system (operationalized by biopotentials) intensity between colonoscopy "with" vs. "without" music is not significant. Alternative hypothesis: The comparison of the sympathetic - autonomic nervous system intensity is significantly higher in colonoscopy "without" music vs. "with" music.
This non-significant risk pilot study is designed to evaluate safety and performance of the CapsoCam® Colon capsule endoscope in patients who meet the eligibility criteria and are scheduled for colonoscopy.
This protocol describes a prospective cohort study. It addresses an important challenge in the prevention of colorectal cancer: how to safely and effectively remove large polyps.
