Filter by:A clinical trial of the effectiveness and safety of intestinal polyp digestive endoscopy-assisted diagnosis software used in the analysis of colonoscopy medical images generated by electronic digestive endoscopy equipment.
To evaluate the safety and effectiveness of ENDOANGEL Lower Gastrointestinal Endoscope Image Auxiliary Diagnostic Software developed and manufactured by Wuhan ENDOANGEL Medical Technology Co., Ltd.
Artificial Intelligence (AI) to predict the histology of polyps per colonoscopy, offers a promising solution to reduce variation in colonoscopy performance. This new and innovative non-invasive technology will improve the quality of screening colonoscopies, and reduce the costs of colorectal cancer screening. The aim of the study is to performed a cross-sectional, multi-center study evaluating the diagnostic performance of the CAD EYE automatic characterization system for the histology of colonic polyps in colorectal cancer screening colonoscopy.
INTRODUCTION: The data obtained by experimental studies about the influence of phytoestrogens on colorectal cancer (CRC) have been very promising. On the other hand, clinical trials have produced conflicting results. The literature suggests that some subclasses of phytoestrogens may have protective effects against CRC and colon adenomas, but most of these results come from population studies based on the dietary intake of phytoestrogens. On these premises, it is possible to hypothesize that the variability of the data reported in the literature may be due to the fact that the real absorption of phytoestrogens (by assessing their concentration in the serum or urine) and/or the ability of the single individual of producing equol was not evaluated. PURPOSE: In the present study, the association between the phytoestrogens intake and the prevalence of colon adenomas was evaluated not only on the basis of the simply dietary intake but also on the measurement their intestinal absorption. Moreover, a specific evaluation of equol production by the intestinal flora was performed. Finally, intestinal bacteria involved in equol production were evaluated.
This study aims to assess the effect, if any, on the adenoma detection rate of BowelScope bowel cancer screening flexible sigmoidoscopies by using the Endocuff Vision device.
The aim of this study is to confirm the TCM syndrome types and TCM constitution classifications of the patients with intestinal polyps via on-site epidemiological survey, to analyze metabolomics of the serum samples of intestinal polyps and healthy volunteers, and to study the metabolomics differences of the two populations and the metabolomics variations of the patients with intestinal polyps of pre-polypectomy and post-polypectomy. Finally, this study is to investigate the serum metabolomics variations of patients with intestinal polyps of pre-polypectomy and post-polypectomy and the relationship with their TCM syndrome types and TCM constitution classifications, to determine the correlation among pathology, TCM constitution, TCM syndrome types and the metabonomics variations of patients with intestinal polyps.
Background:The optimal technique for removal of diminutive or small colorectal polyps is debatable. Objective:To compare the complete resection rates of cold snare polypectomy (CSP) and hot snare polypectomy (HSP) for the removal of adenomatous polyps(3-9mm). Design：Prospective randomized controlled study. Setting：Three tertiary referral hospitals. Patients：we will recruit a total of 330 polyps(3-9mm). Interventions:Enrolled patients were randomly assigned to one of the two polypectomy protocols (CSP vs. HSP) using a computer-generated random sequence. If a patient had one or more polyps, all eligible polyps were removed using the initially assigned polypectomy protocol. After the initial polypectomy, additional EMR was performed at the polypectomy site to assess the presence of residual polyp tissue. Main Outcome Measurements:The primary study outcome was to compare the complete polyp resection rate between groups. Secondary outcomes included rate of postpolypectomy adverse events, including bleeding, perforations,infection and rate of tissue retrieval(Complete resection was defined as the absence of residual polyp tissue in the EMR sections of the polypectomy site).
The aim of this study is to evaluate the usefulness of magnifying colonoscopy with narrow band imaging.
This study will compare two strategies for colonoscope withdrawal, using polyp detection as the primary outcome measure, to determine the optimal withdrawal strategy. Null Hypothesis: On withdrawal of the colonoscope, examining patients with dynamic position change does not yield more polyps than the supine position. Alternative Hypothesis: On withdrawal of the colonoscope, examining the patients with dynamic position change improves polyp detection compared to the supine position.
