Active clinical trials for "Gastrointestinal Diseases"

This is a retrospective and prospective multicenter registry to collect long-term data (1 year) on patients who have or will undergo Endoscopic resection such as EMR, ESD, EFTR, STER, etc. within the gastrointestinal tract for endoscopic treatment of early gastrointestinal neoplasms involving the resection of the superficial layers, mucosa and submucosa, of the tract wall. Subjects will be consented for medical chart review. The purpose of this retrospective and prospective registry is to assess long term data on efficacy, safety and clinical outcome of Endoscopic Resection within the gastrointestinal tract (1 year). The registry will evaluate efficacy, technical feasibility, clinical outcome, safety profile and overall clinical management through medical chart review. The procedures the investigators are evaluating are all clinically indicated and will not be prescribed to someone to participate in this registry study.

The aim of the study is to elucidate the relationship between postnatal antibiotic administration on development of gut microbiota and possible protective influence of simultaneously administration of probiotic during antibiotic therapy on development of gut microbiota, functional gastrointestinal disorders of infancy, weight gain and body composition.

Observational study about the incidence of relative adrenal insufficiency in patients with cirrhosis and acute variceal bleeding; in patients with acute peptic gastrointestinal bleeding and without liver disease; and in patients with severe acute pancreatitis. This is a study using pharmaceutical specialties in the approved conditions of use.

In this study, the investigators proposed a prospective study about the effectiveness of artificial intelligence system for Retrograde cholangiopancreatography. The subjects would be include in an analyses groups. The AI-assisted system helps endoscopic physicians estimate the difficulty of Endoscopic retrograde cholangiopancreatography for choledocholithiasis and make recommendations based on guidelines and difficulty scores. The investigators used the stone removal times, success rate of stone extraction and Operating time to reflect the difficulty of the operation, and evaluated whether the results of the AI system were correct.

Patients aged 65 or older under gastrointestinal surgery will be enrolled，the investigators will assess the frailty of these patients by Frailty Index Scale and explore the correlation between the frailty and perioperative adverse events.

Background: The association of fructose and lactose intolerance and malabsorption with the symptoms of different functional gastrointestinal disorders (FGID) is unclear. The mechanisms behind the multi-organ symptoms remain unclear. Both FGID and saccharide intolerances are common (>10% of any given population). Dietary modification based on intolerance diagnostics could provide an effective treatment for FGID, which are otherwise difficult to treat. Aim: To investigate the prevalence and interrelationships of fructose and lactose intolerance (symptom induction) and malabsorption (breath test gas production) and their association with clinical GI as well as non-GI symptoms in FGID and the outcome of standard dietary intervention. Mechanisms related to symptom genesis will be investigated using metabolomic analysis of plasma and urine by gas chromatography/time-of-flight mass spectrometry (GC/TOFMS). Methods: Fructose and lactose intolerance (defined by positive symptom index) and malabsorption (defined by increased hydrogen/methane) will be determined in successive male and female FGID patients in a single center using breath-testing. Symptoms will be recorded using standardised questionnaires and the Rome III criteria. The prevalence of the intolerances in the different FGID subgroups and the associations between breath testing results, clinical symptoms and the outcome of dietary modification will be assessed. Factors predictive of the outcome of dietary modulation will be screened for. GC/TOFMS will be used to assess the human and microbial metabolome in urine and plasma.

A dietary intervention study designed as a randomized, controlled, parallel intervention of 6-weeks duration. A total of 75 participants will be included in the study and randomly allocated to one of three interventions (refined wheat, whoelgrain wheat or wholegrain rye). Clinincal examinations including anthropometric assessment, fecal, urine and fastign blood sampling, dietary assessment and a meal challenge will be done before (week 0) and after (week 6) the intervention. At timepoints week 0, 2, 4 and 6 questionnaires will be filled in concerning satisfaction with diet and gastrointestinal symptoms.

The aim of the EUS registry is to record information about Endoscopic Ultrasound (EUS) on the management of gastrointestinal disease. The registry will evaluate efficacy, safety and technical success of the Endoscopic Ultrasound (EUS). Design is retrospective and prospective registry study.

Randomised controlled trial comparing standard outpatient clinic treatment with multi-disciplinary clinic treatment for functional gastrointestinal disorders. Patients will be followed up to end of clinic treatment and 12 months beyond the end of treatment. Symptoms, quality of life, costs to the healthcare system and psychological outcomes will be assessed.

The oligosaccharide content (raffinose, stachyose, and verbascose) in legumes would be responsible for gastrointestinal symptoms (bloating, pain, meteorism), associated with its consumption. We would evaluate consumption of 3 varieties of chilean native beans, and evaluate gastrointestinal symptoms produced along with expired H2 test, to correlate this with the amount of oligosaccharide content.
