Filter by:This study aims to evaluate the feasibility and safety of Cold snare polypectomy for removing 5-9mm small intestinal polyps in patients with Peutz-Jeghers Syndrome (PJS),in order to provide some reference for clinical strategy of endoscopic treatment of small intestinal polyps in PJS patients, and may prolong the follow-up period of PJS patients Intervals.
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.
The study authors hypothesize that in patients with intestinal polyps, tumor cells could disseminate and circulating factors could be secreted by the polyp. These two parameters could become biomarkers to refine the follow-up of patients and to establish targeted therapeutic strategies.
Colorectal cancer is the 2nd most common cause of death by cancer. Screening is therefore essential, with a positive impact for prevention, and in the visualization and removal of colonic adenomas, pre-cancerous lesions of colorectal cancer. The colonic adenoma detection rate (CADR), the gold standard for colonoscopy screening and screening studies, is the ratio of the number of colonoscopies with at least one histologically verified colonic adenoma to the total number of colonoscopies performed in a center. It varies between 25 and 45% depending on the center. There is a large inter-operator CADR variability, which has been linked to an increased incidence and excess mortality in colorectal cancers. To improve this detection rate, several innovative techniques have been developed: The endoscopic cap helps improve this detection rate: it is a 2cm tip with double row of plastic wings, fixed to the distal end of the colonoscope, which acts by unfolding the colonic haustrations allowing a better visualization of adenomas, and more particularly those of sessile morphology and sigmoidal location. Several multicenter studies have shown an improvement in the adenoma detection rate with this device compared to screening colonoscopy alone, with an adenoma detection rate optimization of 14%. Since then other devices, such as the Endocuff, have emerged with comparable efficacy. The Medtronic© GI GENIUS system integrates artificial intelligence (AI) to assist in the detection of polyps. It automatically identifies these precancerous lesions in real time. The study investigators previously performed a retrospective pilot study (COLODETECT), comparing colonoscopy alone as a control group, against AI alone and against the combined cap + AI. This study showed encouraging results in terms of colonic adenoma detection rate (60% for the AI + cap group versus 37% for the AI alone group versus 33% for the colonoscopy alone group, p=0.037) However, it requires a higher level of evidence to be validated in practice. This prospective COLODETECT2 study estimated an a priori expected difference between A.I. - Cap and A.I. alone of about 15% CADR. The GI GENIUS artificial intelligence system and the ENDOCUFF VISION endoscopic cap have separately proven their effectiveness in terms of colonic adenoma detection compared to colonoscopy alone. However, some limitations remain: existence of false positives (mucosal folds, residues), some morphological types still difficult to recognize (scalloped adenomas), non visualized colonic lesions. This study therefore focuses on the possible complementarity of these 2 medical devices, in order to maximize the detection rate of colonic adenomas, and thus overcome the limitations of these two techniques by optimizing the visualization of these precancerous lesions, and consequently increasing the impact of colorectal cancer screening. The study authors hypothesize that the combination of GI GENIUS™ AI coupled with the ENDOCUFF VISION® endoscopy cap provides a better colonic adenoma detection rate (CAD) during colonoscopy than either GI GENIUS™ AI alone or the ENDOCUFF VISION® cap alone.
Obesity is associated with adverse airway events including desaturation during deep sedation. Previous studies have suggested that high-flow nasal oxygenation may be superior to regular (low-flow) nasal cannula for prevention of hypoxia during Sedated Gastrointestinal Endoscopy in non-obesity patients. The prerequisite of high-flow nasal oxygenation is keeping airway patency. Our pervious study demonstrated that nasopharyngeal airway has the similar efficacy of jaw-lift. In present study we aimed to determine whether high-flow nasal oxygenation combined with nasopharyngeal airway could reduce the incidence of hypoxia during Sedated Gastrointestinal Endoscopy in obese patients.
Ciprofol is a new anesthetic, which combines with γ- Aminobutyric acid-a (GABAA) receptor. Ciprofol has shown equivalent anesthetic efficacy of propofol at 1/4 to 1/5 of the dosage. Ciprofol has the pharmacodynamic characteristics of rapid onset, stable and rapid recovery. Phase III clinical results showed that the incidence of injection pain and respiratory and circulatory depression of ciprofol was lower than that of propofol. Therefore, ciprofol has a good application prospect in sedation for gastrointestinal endoscopy, especially for obese patients. In the current study, we would explore the proper dose of Ciprofol in sedated gastrointestinal endoscopy in obese patients.

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.
