Filter by:The tongue images of patients with gastrointestinal diseases and healthy people will be collected and the tongue image database will be established. Through deep learning and artificial intelligence, early screening models of various gastrointestinal tumors based on tongue images were constructed.
This study will assess the safety, efficacy, and pharmacokinetics of THE-630 in participants with advanced gastrointestinal stromal tumors (GIST).
Inflammatory activities in the gastrointestinal tract are accompanied by an increase in blood flow in the intestinal wall layers of the respective organs. Also in chronic inflammatory bowel diseases, the release of vasoactive inflammatory mediators leads to vasodilation and consecutive increase of blood flow in the bowel wall. So far, these changes in blood flow can be detected by power Doppler sonography without being part of routine clinical diagnostics. Another promising option for non-invasive measurement of blood flow in the intestinal wall is Multispectral Optoacoustic Tomography (MSOT). Previous studies have shown that MSOT can be used to quantitatively measure hemoglobin in the bowel wall and thus provide information on blood flow and inflammatory activity in the intestines of patients with Crohn's disease. This is currently being further investigated in a pivotal study (Euphoria, H2020) and could lead to the possibility of non-invasive assessment of disease activity in inflammatory bowel disease (IBD) in the future. The regional blood flow in the intestinal wall and the distribution of gastrointestinal blood flow are also subject to strong postprandial changes. During absorption of food components, blood flow increases sequentially in the respective sections of the gastrointestinal tract, leading to postprandial hyperemia. Because postprandial hyperemia is particularly regulated locally by the presence of dietary components, there is a relationship between the sequential increase in blood flow in the intestinal wall and the peristaltic transport of chyme through the gastrointestinal tract. Postprandial hyperemia could also lead to an increase in the optoacoustic hemoglobin signal of the intestinal wall and thus have an impact on the assessment of inflammatory activity in IBD using MSOT. Additionally, MSOT allows the identification of non-absorbable exogenous chromophores, such as indocyanine green (ICG), which could allow co-localization of the chyme in the intestinal lumen after oral application of ICG. This pilot study investigates whether postprandial blood flow changes can be quantitatively measured using MSOT and whether these changes occur simultaneously with the gastrointestinal passage of the chyme as measured by the ICG signal in the intestinal lumen.
Human-computer interactions or 'Chatbots' have been utilized in a variety of healthcare settings, including the promotion of positive healthcare behaviors, the deliverance of psychological therapy, and the performance of diagnostic tasks. Standard methods of consenting patients for procedures may not always result in patients being fully informed; a 2004 study of patients undergoing screening sigmoidoscopy demonstrated that 39% of surveyed patients could describe no other indication than doctor recommendation for the procedure after undergoing standard consent. his study seeks to investigate the usability of a novel chatbot designed to provide peri-procedural information in two endoscopic procedures - diagnostic oesophagogastroduodenoscopy (OGD) and diagnostic colonoscopy. A novel Chatbot - 'SurgInfoBot' has been developed in order to provide real-time, patient-driven peri-procedural information. This study primarily seeks to assess the effect of SurgInfoBot use on patient satisfaction with the consent process in endoscopy. It will also assess the usability of the chatbot according to the system usability scale and test performance according to the as-yet unvalidated Chatbot Usability Questionnaire (CUX). User engagement will be analyzed objectively using stored metrics. Comparison will be made between perceptions of the SurgInfoBot as an information source and other established patient information sources. The potential impact of the SurgInfoBot on peri-procedural anxiety will also be explored.
Irritable bowel syndrome (IBS) is a functional disorder causing troublesome symptoms and reduced quality of life. It affects 10-20% of the population, hence creates large costs for society. About 30-40% of all IBS patients do not benefit from current treatment options. Sucrase-isomaltase (SI) deficiency is an unexplored condition, that may explain symptoms in IBS patients who experience no effect from today's treatments. Currently, a duodenal biopsy is the gold standard for the diagnosis of SI deficiency, however the condition is not well investigated. A 13C-labelled breath test holds promise as a non-invasive alternative, but it has not previously been validated. This project will address the knowledge gap related to a possible association between SI deficiency and IBS by addressing two research questions that have never been answered before. We aim to: 1. Validate the 13C-labelled breath test as a diagnostic tool by assessing the strength of the association between the breath test and SI activity measured in duodenal biopsies 2. Use the 13C-labelled breath test in a randomized dietary crossover trial comparing a starch and sucrose reduced diet (SSRD) with the standard low-FODMAP diet in IBS patients, to evaluate whether SI activity is associated with dietary changes according to symptom severity and gut microbiota composition
This study involves a comprehensive nutritional assessment of hEDS participants who have functional gastrointestinal disorders and dietary intervention to broaden their food choices and nutritional intake.
This is a combined retro- and prospective, monocentric study. All patients who underwent or are planned for laparoscopic partial fundoplication (180° anterior or 270° posterior) between 2020-2023 are assessed for preoperative ineffective esophageal motility (IEM). The main hypothesis is, that preoperative oesophageal motility disorders, especially hypo-contractility or failed peristalsis, are caused by gastro-oesophageal reflux. Therefore, postoperative manometry after partial wrap fundoplication (270° posterior, 180° anterior) shows a decrease in comparison to preoperative motility disorders. The primary objective of this study is to examine the postoperative esophageal motility in patients with known preoperative motility disorders. Secondary endpoints are the presence of other oesophageal motility disorders pre- vs. postoperatively (including new onset disorders), the assessment of the Gastrointestinal Symptom Rating Scale (GSRS) pre- vs. postoperatively, and more. If IEM is present preoperatively, patients are contacted at least 1 year after surgery and will be informed about the study and asked to participate. In case of agreement, they are invited to the study site. They undergo high-resolution manometry 18-24 months postoperatively (study intervention).
The purpose of this prospective registry is to assess long-term data on efficacy, safety and clinical outcome of endoscopic placement of suture(s) and approximation of soft tissue within the gastrointestinal tract for various GI tract disorders. Currently, lack enough data evaluate and verify technical feasibility, clinical success and safety of endoscopic suturing in specific gastrointestinal disorders.1-16 Evaluation of these factors would help us compare them to conventional treatment modalities; and consequently help us identify appropriate treatment techniques and improve clinical management of patients.
This study will be a retrospective, registry study collecting data of patients who were diagnosed with benign or malignant gastrointestinal diseases. Data will be collected from patient's chart retrospectively once the patients have completed proper treatment follow up with physicians' practice.
Antidepressants are effective in patients with functional dyspepsia (FD), however, the stigma related with FD and antidepressants could affect treatment adherence and efficacy. Zhi Zhu Kuan Zhong capsules (ZZKZ), a traditional Chinese medicine fomula, showed therapeutic potential for FD. The study was designed to investigate whether ZZKZ could alleviate stigma in FD and obtain identical effects in patients with refractory FD.
