Active clinical trials for "Digestive System Diseases"

The goal of this clinical research study is to learn if the results of a positron emission tomography/computed tomography (PET/CT) scan done 10-14 days after beginning chemotherapy and radiation (chemoradiation) can predict how a patient with cancer of the esophagus will respond to chemoradiation. Researchers also want to learn if biomarkers (substances in the body associated with cancer) found in tumor tissue can predict response to chemoradiation.

The definition of Functional Gastrointestinal Disorders (FGIDs) has changed over time from the absence of organic disease to a stress-related or psychiatric disorder to a motility disorder, and with Rome III, to a disorder of GI functioning, then Rome iv in 2016 defined FGIDs as : disorders of gut-brain interaction. It is a group of disorders classified by GI symptoms related to any combination of the following: motility disturbance, visceral hypersensitivity,altered mucosal and immune function, altered gut microbiota, and altered central nervous system (CNS) processing. FGIDs are observed in infants and young children worldwide with variable frequency related studies done in variable places around the worled show the following results : the prevalence of FGIDs in Chinese infants and young children is 27.3%.and 40 % in south american infants and 30 % of african infants and 35.1 % of infants presented to tertiary care hospital in Istunbul.Turkey.

The disease activity index under intestinal color ultrasound was evaluated by SUS-CD, and the disease activity index under capsule endoscopy was evaluated by CECDAI. All subjects underwent intestinal color ultrasound and capsule endoscopy at baseline and at the third month of treatment. To compare the correlation between SUS-CD and CECDAI before and after treatment, and to compare the role of intestinal color ultrasound and capsule endoscopy in monitoring Crohn's disease in small intestine.

Sixty patients scheduled for upper diagnostic gastroscopy were randomised after written informed consent into three groups. transnasal gastroscopy with thin endoscope transoral with thin endoscope standard size trans-oral endoscopy Stress response parameters (epinephrine, nor-epinephrine and cortisol, heartrate variability data and pulse oximetry data were monitored.

Aim of study: Primary Outcomes: Patients with ulcerative colitis-associated upper gas- trointestinal inflammation may require specific treat- ment for the gastroduodenal lesions. Hence, recogni- tion and detection of the upper gastrointestinal lesions are important. Here we describe 2 cases of ulcerative colitis and summarize the results of our investigation of the prevalence of upper gastrointestinal involvement detected by esophagogastroduodenoscopy. We also analyzed the macroscopic and microscopic features of the upper gastrointestinal lesions Secondary Outcomes: correct and timely treatment of upprt GIT lesions in UC .

Flexible endoscopes are used globally for the diagnosis and treatment of diseases of the GI tract. Duodenoscopes used for Endoscopic Retrograde Cholangiopancreatography (ERCP), in order to treat different biliary and pancreatic disorders, have been recently linked to infections transmission following the procedures. Given their reusability and their complex design of the tip with a moving metallic component, named the "elevator", these instruments must be reprocessed through high level disinfection (HLD) in order to prevent the spread of nosocomial infections. Even strict adherence to all HLD procedures results in a residual level of potentially infectious microbes. In fact, the United States Food and Drug Administration (FDA) postmarket surveillance communication reported duodenoscope culture results demonstrating contamination rates of up to 3.6% for low and moderate-concern organisms and up to 5.4% for high-concern organisms in reprocessed conventional duodenoscopes. As a consequence, at least 20 outbreaks of duodenoscope-transmitted multidrug resistant organism (MDRO) infections occurred between 2012 and 2015, despite reported compliance with duodenoscope reprocessing guidelines. The increasing concern that currents practices of reprocessing reusable duodenoscopes is insufficient, has led the FDA to released recommendation suggesting to develope a newly designed duodenoscopes. On one hand, a way is to generate duodenoscope with disposable components, such as a one-use end cap, which can be removed and allow access to the components of the elevator and other areas of the duodenoscope for reprocessing. On the other hand, an alternative is to produce a fully disposable single-use duodenoscope. The evident advantage of a single use duodenoscope, over disposable components, is that it completely eliminates the need for reprocessing and more important the risk of transmitting microbial infection from patient to patient.

Neonates with congenital/acquired gastrointestinal disorders are at high risk for Parenteral Nutrition Associated Cholestasis (PNAC). Besides enteral nutrition, standard therapies to prevent and treat PNAC have been limited and marginal. Recently, the dose and composition of standard intravenous fat emulsions have implicated in the development and progression of PNAC. In this study, neonates with congenital/acquired gastrointestinal disorders will be randomized, in a unblinded fashion, to receive either the standard dose of an intravenous omega-6 fatty acid emulsion or a low dose of an intravenous omega-6 fatty acid emulsion throughout their course of PN or until hospital discharge, death or 100 days of life, whichever comes first. The primary outcome will be the presence of cholestasis.

The primary purpose of this exploratory study is to measure orocecal transit time using the SmartPill ambulant capsule technology and to compare this with the lactulose hydrogen breath test. Additionally, the ability of the SmartPill GI Monitoring System to discriminate between healthy human subjects and patients with small bowel bacterial overgrowth will be explored using analyses of both pH and pressure patterns within the stomach and small intestine. The study will be performed in both normal subjects and patients with and without small bowel bacterial overgrowth.

The Gastroparesis Registry 4 (GpR4) is an observational study of patients with symptoms of gastroparesis (Gp) and functional dyspepsia (FD) with either delayed or normal gastric emptying. To better understand these disorders, this registry will capture demographic, clinical, physiological, questionnaire, and patient outcome data to characterize the patients and their clinical course. Participants will complete several questionnaires, complete a nutrient drink test and have a gastric emptying study.
