Filter by:Colonoscopy is an endoscopic procedure for diagnosing colon diseases. Patients should be prepared 2-5 days in advance for this procedure and intestinal cleansing should be provided. This is a difficult process and does not admit mistakes. The adequacy of the patient's pre-preparation for this process increases the chances of success. For preliminary preparation, it is recommended to train the patient and reinforce the trainings by phone. Education given to the patient; It contributes positively to patient outcomes, the workload of healthcare personnel in the institution, and costs. Therefore, this study has been planned.
This is a noninferiority study designed to examine whether conscious sedation with midazolam alone results in efficacy and safety that is not inferior to the combination of midazolam and fentanyl. English-speaking patients ≥18 years old and ≤75 years old presenting for GI endoscopy planned with conscious sedation using midazolam and fentanyl, will be randomized 1:1 to single agent sedation with midazolam or combination sedation with midazolam and fentanyl. Participants will be blinded to the choice of sedation. Sedation quality and adverse events will be measured with a validated patient-centered measure of procedural sedation quality, the PROcedural Sedation Assessment Survey (PROSAS) [Leffler, et al. Gastrointest Endosc. 2015;81(1):194-203]. Endoscopic quality measures in the 2 study groups will be collected by retrospective chart review, as an additional metric to ensure the quality of the procedure is not compromised by the choice of sedation.
This is a study to compare the left colon mucus production between carbon dioxide (CO2) insufflation and water exchange (WE) colonoscopy in patients that require a routine or repeat colonoscopy. There will be four arms in this study: CO2 insufflation (control group 1), WE with water infusion (control group 2), WE with 50% saline infusion (study group 1), and WE with 25% saline infusion (study group 2). The patient will prepare himself/herself for the colonoscopy as per normal instructions and he/she will be given the information for the study at that time so that he/she can make a decision to participate in the study. The WE control group will use sterile water filling during colonoscope insertion. The study method will use saline filling during colonoscopy insertion. This study will confirm if using the saline infusion is a better method in reducing mucus production when WE colonoscopy is used.
Bowel cancer is the 3rd most common cancer in males and females. Most bowel cancers develop from precancerous polyps in the bowel. Colonoscopy can detect and remove these polyps, thereby reducing the risk of developing bowel cancer. However, colonoscopy is an invasive procedure with inherent risk, and can be both uncomfortable and embarrassing to undergo. The risks and numerous other barriers often mean colonoscopy, and cancer preventing polyp removal, is not performed. The investigators aim to start the first in-human feasibility clinical investigation of a robotic magnetic colonoscope in 2021. The new device aims to reduce the discomfort and risk associated with colonoscopy. As part of the patient and end user involvement aspect of the project the investigators aim to perform a mixed methodology inductive type research project exploring experiences of colonoscopy for patient and endoscopists. The study will follow an exploratory mixed methodology format with two parallel work-streams for patients and endoscopists. Each work-stream will consisting of a focus groups (1-2 for each patients and endoscopists), followed by 20 endoscopist and 30 patient in-depth interviews, then an online questionnaire. Each stage will be thematically analysed to form the semi-structured questions for the next stage. The target population will be endoscopists who perform colonoscopy and people who have undergone, or refused to undergo, a colonoscopy. Focus groups will be performed in groups of 6-10 participants, and both interview and focus groups will be performed via video/teleconferencing.
The study was planned as a randomized controlled experimental study to determine the effect of virtual reality glasses used during a colonoscopy on vital signs, pain, and anxiety level. After the approval of the ethics committee and institutional permission, 60 patients who applied to the endoscopy unit for colonoscopy procedure between 1 October 2020 and 1 October 2021 and met the inclusion criteria will be included in the study. Within the scope of the planned study, the sample size in the light of the reported academic studies was determined as effect size d = 0,665 (effect size), α = 0.05 (margin of error), 1-β = 0.80 (Power) and by using the G-Power package program with the specified criteria. It was decided to recruit 58 people (29 people per group). The block randomization method will be used to determine the experimental and control groups. In order for the groups to be distributed homogeneously, the order produced by a computer program (https://www.randomizer.org/) will be used. Randomization will be done by a biostatistician outside the researcher. Patients who meet the inclusion criteria and agree to participate in the study will be assigned to the experimental and control groups according to the randomization list. Before the colonoscopy, the patient will be visited and information will be given about the purpose, content, and intervention to be applied. After obtaining verbal and written consent from the patients who accepted to participate in the study, the "Individual Characteristics Form" will be filled. Then, before the colonoscopy procedure, the anxiety states of the patients in the experimental and control groups will be asked with the "State and Trait Anxiety Inventory", their pain status with the Analog Scale (VAS), and their first life findings will be measured and the first measurement values will be recorded in the "Vital Signs Follow-up Form". The patients in the experimental group will be informed about the virtual glasses before the colonoscopy procedure and the virtual reality glasses will be placed on the patient's head during the procedure. Then, during the colonoscopy procedure, the duration of the colonoscopy will vary between 3-10 minutes, and during the colonoscopy period, videos with music background, parks, nature and seaside walks, underwater, etc., will be watched by the patient and the "Vital Signs Tracking Form" The second measurement values will be saved by making measurement to. Immediately after the colonoscopy procedure is finished, "Visual Analogue Scale (VAS)", "Life Findings Follow-up Form" (measurement will be made and 3rd measurement values will be recorded. The "State Anxiety Inventory" will be read and the answers will be recorded. The standard application will be applied to the patients in the control group during the colonoscopy procedure and the second measurement values will be recorded by measuring the "Vital Signs Follow-up Form".Immediately after the colonoscopy procedure is completed, the third measurement value will be recorded by measuring the "Visual Analogue Scale (VAS)" and "Vital Signs Follow-up Form". "State Anxiety Inventory" will be read and the answers recorded.
This was a prospective, randomized, single-blind controlled clinical trial comparing three sedative regimens for outpatient colonoscopy.
Colorectal cancer screening program has been proven to reduce colorectal cancer (CRC) mortality and is cost-effective. It has been adopted by most countries in the world, and colonoscopy is regarded as the most accurate test for detecting colorectal neoplasm. After screenees underwent colonoscopy, most endoscopists do not routinely explain the preliminary optical diagnosis to the subjects before they going home, which may cause unnecessary anxiety and may reduce the quality of life of the subjects before acquiring the final results. In recent years, endoscopic optical diagnostic technology has been validated by meta-analysis studies as an excellent tool to predict the histology of colorectal polyps and to differentiate the invasion depth of colorectal cancer. The real time feature of endoscopic optical diagnosis allows endoscopists to explain the preliminary results confidently to the subjects immediately after colonoscopy, which is expected to reduce the anxiety of the subjects before they acquired the final results and improve their quality of life. We designed a randomized controlled trial to validate whether real-time endoscopic optical diagnosis could decrease the anxiety burden and improve the quality of life for colorectal-cancer screenees after colonoscopy.
Randomized Clinical trial between two positions to initiate colonoscopy, Right Sided vs Left Sided
Bowel preparation regimens typically incorporate dietary modifications along with oral cathartics. Inadequate bowel preparation can result in failed detection of prevalent neoplastic lesions and has been linked to an increased risk of procedural adverse events. Previous studies have suggested that patient compliance is important to ensure proper bowel cleansing. Patient counseling along with written instructions that are simple and easy to follow and in their native language should be provided to patients. Thus, interventions that improve the quality of bowel preparation could have a great benefit regarding colonoscopy results. Little in the literature that studies the impact of enhanced patient education on bowel preparation quality. In this study we aim to determine the impact of patient education using telephone call one day prior to outpatient colonoscopy on bowel preparation quality.
In order to obtain the risk level of patients with intestinal insufficiency through simple indicators, many foreign scholars have studied and developed their own prediction models. However, the current guideline indicates that there is insufficient evidence to recommend the use of a specialized predictive model for clinical practice.There are few studies on external validation of existing prediction models.
