Filter by:Several randomised studies have shown that the addition of low-dose Simethicone to the bowel preparation was sufficient to reduce the presence of bubbles during colonoscopy. The aim of this study was to evaluate the efficacy and safety of a bowel preparation containing low-dose Simethicone on bubble formation. Patients and Methods This prospective, real-life, phase 4 study was conducted from February 2020 to May 2021, in five private endoscopy centres, among adult patients undergoing a colonoscopy. Clinical, endoscopic and histological parameters were collected on e-CRF. The primary endpoint was the measurement of bubble formation in the various colon segments.
Background and Aims: The quality of colonoscopy is critically influenced by bowel preparation. Polyethylene glycol (PEG) is considered the gold standard regimen for bowel preparation, however due to the necessity of large volume of patient's tolerance is impaired, especially in the elderly population. Lactulose has been adopted in a few centers as a novel alternative for colonoscopy preparation. This study aimed to investigate the efficacy-safety profile of a lactulose-based bowel preparation in comparison to PEG for colonoscopy. Methods: Prospective non-blinded comparative study, developed in two tertiary centers from July 2021 to April 2023. Outpatients undergoing colonoscopy were randomly divided into 2 groups: Group 1 (111 patients): PEG and Group 2 (111 patients): Lactulose. The following clinical outcomes were assessed for each group: degree of bowel clearance using the Boston Score, colorectal polyp detection rate, adenoma detection rate, tolerability and side effects.
The goal of this observational study was to assess the degree of agreement between the endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions in adult patients undergoing colonoscopy in Hospital Sírio-Libanes. The main questions it aimed to answer were: - The degree of agreement between endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions by calculating the Kappa Value of agreement. - To establish the detection rate of sessile serrated lesions and adenomas in the Endoscopy Department at Hospital Sírio-Libanês. - To evaluate the degree of agreement between endoscopic and anatomopathological diagnosis of sessile serrated colorectal lesions based on the resection method. - To assess the accuracy, positive predictive value, and negative predictive value of endoscopic diagnosis of serrated lesions compared to anatomopathological diagnosis. The data were prospectively collected through a form specifically designed for this project, that was completed immediately after the examination by the performing colonoscopist. All patients enrolled in this study agreed to participate in it and signed an informed consent form prior to the colonoscopy.
In this study, the investigators aim to evaluate the relationship between cecal intubation time during colonoscopies and factors such as the patient's age, body mass index, history of constipation, Wexner constipation score, antidepressant use, and previous abdominal surgery. The objective is to assess factors that may predict longer cecal intubation times, especially in difficult colonoscopies. Prior to the procedure, informed consent will be obtained from patients scheduled for colonoscopy in the surgical endoscopy unit, and relevant information will be recorded. During the procedure, data will be collected, including cecal intubation time, if ileal intubation is performed, and the total procedure time.
The investigators plan to adopt a thorough flushing strategy when withdrawing the endoscope, and have zero tolerance for the liquid and foam in the intestinal lumen. Observe and compare the impact of this strategy with traditional limited degree suction methods on the results of colonoscopy. The research group and the control group respectively adopted a thorough flushing strategy and a limited flushing strategy, and compared the total time of colonoscopy examination, the time of withdrawal, the detection rate of polyps, the detection rate of small polyps, and the amount of flushing fluid between the two groups. Analyze the value of thorough flushing strategy for the efficiency and quality of colonoscopy examination.
Colonoscopy is a complex, highly operator dependent, practical skill. The consistent attainment of key performance indicators (KPIs) by endoscopists depends primarily upon training. Local factors can make training unstructured and contingent upon the observed practice of a small number of trainers. The investigators sought to demonstrate the feasibility and impact of a virtual-live one day colonoscopy-training course.
In this study, the investigators will evaluate the ability of the Magnetic Flexible Endoscope (MFE) to travel through the human colon. The MFE is a device made of ultra-flexible tubing that contains a camera, light, and magnet at the tip. The tip of the tube is about the size of a penny. The magnet inside the tip allows the MFE to be moved through the colon by a second magnet attached to a robotic arm that is outside the body. The objective of this feasibility study is to determine safety and tolerability of the Magnetic Flexible Endoscope (MFE) traveling in the human colon.
Aim: This study aimed to evaluate the effect of abdominal massage on pain and distention in patients who underwent colonoscopy. Methods: This randomized controlled study was conducted between October 2019 and December 2021 with the participation of 60 patients who underwent colonoscopy in the endoscopy unit of a university hospital. Thirty patients performing abdominal massage after colonoscopy were included in the experimental group.
Colonoscopy is the gold standard in bowel assessment when there is suspicion of colon and rectum pathology. Bowel cleansing is necessary to ensure an optimal visualization of colonic mucosa, allowing this form of detection and removal of polyps. Nowadays international recommendations have multiple bowel preparations. There are differences among them regarding adherence, tolerance and adverse effects. Lactulose (LAC) is widely used in treating constipation. However, there are some randomized clinical assays using LAC as bowel preparation with excellent results according to bowel preparation and tolerance scales. Adherence to bowel preparation significantly affects the result in the endoscopic study. Safety of polyethylene glycol (PEG) formulations has been validated in several studies, it presents little severe side effects and the advantage of its applicability to patients with several comorbidities (heart, liver and kidney without water deprivation). However, its main disadvantage lies in the need to ingest large amounts of liquid (3-4L), generating intolerance thereto in 15%-45% of patients. Bowel cleansing preparation with PEG is widely used in clinical practice. Considering that according to international studies reporting better tolerance and adherence with LAC; it is suggested to compare the level of bowel preparation, tolerance and adherence between two groups with LAC and PEG.
This project will use a randomized controlled trial to test the effect of using Virtual Reality on pain, anxiety, patients' comfort, and satisfaction during colonoscopy. Patients will use a virtual reality head-mounted display and choose a visualized VR content to watch during colonoscopy. Colonoscopy will be initiated without standard sedatives and narcotics and using virtual reality distraction for as long as the patient would like (for a maximum of 20 minutes). Participants could opt out and/or request standard medications for pain at any time before or during the procedure.
