Filter by:This study was planned to examine the effect of bowel preparation training and monitoring given to patients planned to undergo colonoscopy on the level of anxiety, compliance with bowel preparation and bowel cleansing. The research sample was collected at the Sultan II. University of Health Sciences affiliated to the Istanbul Provincial Health Directorate between December 2022 and August 2023. 34 intervention and 34 control groups will be randomly selected from outpatients who apply to the Colonoscopy Unit of Abdülhamid Han Training and Research Hospital and meet the inclusion criteria. In this study, it is aimed to increase the effect of bowel preparation training, supported by nurses in the clinic and via instant messaging/calling or communication application, on patients' anxiety level, level of compliance with bowel preparation, and bowel cleansing in patients scheduled for colonoscopy.
The goal of this observational study is to learn about Influencing factors of intestinal microecological changes before and after colonoscopy. The main questions it aims to answer are: - [question 1] The process of colonoscopic gas insufflation affects the intestinal microecology. Will the use of carbon dioxide gas insufflation can reduce the changes of intestinal microecology after colonoscopy? - [question 2] Can the appendix act as a reservoir for microorganisms to accelerate the recovery of intestinal microecology after colonoscopy？ Participants will be asked to accept colonoscopy for once. Group 1(Control group) will be insufflated air during the colonoscopy; Group 2(Carbon dioxide group) will be insufflated carbon dioxide during the colonoscopy; Group 3(After appendectomy group) will be insufflated air during the colonoscopy. Since Group 1 is comparison group, the investigators will compare Group 2 to see if carbon dioxide gas insufflation can reduce the changes of intestinal microecology after colonoscopy. Meanwhile, compare Group 3 to see if the appendix can accelerate the recovery of intestinal microecology after colonoscopy.
Water exchange (WE) method has been shown to reduce medication requirement and pain experience during the colonoscopy. Cap-assisted colonoscopy aided by air may also reduced the insertion pain. Therefore, the immediate aim of this study is to assess the generalizability of the impact of WE plus cap (WECAC), as a potentially less painful insertion technique than WE. The control group will use water infusion in lieu of air insufflation during insertion of the colonoscope. The study group will added a cap onto the end of colonoscope during the WE method procedure. This study will also demonstrate if the WECAC method have a shorter insertion time and higher proximal colon adenoma detection rate (ADR) than WE alone in Veterans.
It is standard practice in the United States and many parts of world to perform Gastrointestinal endoscopy with the patient under deep intravenous sedation. Obesity is accepted as a patient specific risk factor for hypoxic events during procedural sedation for GI endoscopic procedures. The obese population has a higher prevalence of obstructive sleep apnea (OSA), which is characterized by repeated obstruction of the upper airway, and leads to apnea and desaturation. This prospective, randomized study was designed to compare the effectiveness of the high flow nasal cannula, standard nasal cannula and standard face mask in morbidly obese patients with a high risk of sleep apnea, (BMI greater than 40, STOPBANG greater or equal to 5) receiving deep intravenous sedation during colonoscopies. This study will assess which method leads to a lower incidence of intraoperative desaturation events compared to the current standard of care.
The purpose of this study is to determine residual gastric volume and residual gastric pH in patients undergoing combined EGD and colonoscopy comparing the standard single dose prep with the split dose bowel preparation and same day bowel preparations.
The purpose of the investigators study is to evaluate the diagnostic ability of a new immunological fecal occult blood test in Cuban patients undergoing colonoscopy .
