Active clinical trials for "Intestinal Diseases"

The main clinical hypothesis is that compared to radio-chemotherapy for low and mid rectal tumors or surgery for high rectal tumors neoadjuvant chemotherapy reduces the rate of distant relapse without increasing the rate of local relapse. The aim of the present study is to compare long term and short term outcomes in rectal cancer patients undergoing standard treatment (radio-chemotherapy/surgery) or experimental neoadjuvant chemotherapy/surgery Furthermore, early surgical and medical complications, the functional outcome, toxicity and quality of life (QoL) may be improved if radiotherapy can be avoided. Exploratory analyses are planned in order to find potential predictive markers for selecting patients to either radio-chemotherapy/surgery or neoadjuvant combination chemotherapy/surgery.

This study will be a single center, prospective triple blinded randomized controlled study, comparing the use of liposomal bupivacaine (Exparel) to regular bupivacaine with adjuncts in bilateral mid-abdominal transverse abdominis plane (TAP) blocks for patients undergoing laparoscopic colectomy procedures.

The goal of this clinical trial is to study the effect of peppermint oil in in children with bladder and bowel dysfunction. The main question it aims to answer is: Does peppermint oil improve symptoms of bladder and bowel dysfunction among children? Participants will: Be provided peppermint oil capsules to be taken 3 times daily for 8 weeks. At baseline and at a follow-up visit (8 weeks later), participants will be asked to complete the Vancouver Nonneurogenic Lower Urinary Tract Dysfunction/Dysfunctional Elimination Syndrome Questionnaire. Researchers will compare baseline and follow-up questionnaire data for each participant to determine if there is improvement in symptoms of bladder and bowel dysfunction.

Study to determine whether the use of an ultrasound completed during an inflammatory bowel disease (IBD) clinic will speed up diagnosis, treatment initiation, reduce complications, save money and reduce investigations compared with our current standard of care.

Background: Bacteria that live inside the stomach and intestines are important for health. Chronic granulomatous disease (CGD) and inflammatory bowel disease (IBD) can make people have unhealthy bacteria. This can lead to gastrointestinal (GI) problems. Researchers want to see if people with CGD and IBD feel better when they change the bacteria in the stomach by following a special liquid diet. Objective: To see if an elemental diet can change the bacteria in the stomach and intestines of people with CGD and IBD. Also, to see if this helps GI symptoms. Eligibility: People ages 8-65 years with CGD, CGD-associated colitis, and IBD. Design: Participants will first be screened with: Upper GI endoscopy and/or colonoscopy. A long, thin tube with a tiny camera at the end will be passed into the participant s body through the mouth or anus. Tissue will be collected. Participants will be sedated for the procedure. They will be sedated using a special mask or small plastic tube placed in an arm vein using a needle. Participants will be put on the special diet for up to 4 weeks. They will stay in the hospital for the first 1-2 weeks. They will have check-ups. They will have blood, urine, and stool samples collected. They will keep a symptom diary to record how they feel and any GI symptoms. Participants will have 2 follow-up visits. The first will be right after they finish the diet. The second will be 4 weeks later. They will have blood, urine, and stool samples collected. They will learn about re-introducing other foods into their diet.

IMPROVE-IT2 is a randomized multicenter trial comparing the outcomes of ctDNA guided post-operative surveillance and standard-of-care CT-scan surveillance. The hypothesis of this study is that ctDNA guided post-operative surveillance combining ctDNA and radiological assessments could result in earlier detection of recurrent disease and identify more patients eligible for curative treatment.

The study will compare the effectiveness of Bezlotoxumab in individuals with active C. diff ( Clostridium difficile) infection who are diagnosed with Inflammatory Bowel Disease.

The goal of this study is to explore in a cross over randomized controlled trial, the ability of the Tasty&Healthy dietary intervention (NCT04239248) to alter the parameters associated with future risk of developing Chron's disease (CD) using subjects identified in the Genetic Environmental Microbiome (GEM) Study as having a high-risk score. Specifically, the investigators aim to determine if the Tasty&Healthy dietary intervention can decrease the overall GEM Risk Score (GRS) and/or to alter the individual biological parameters that contribute to this score. The investigators hypothesize that the Tasty&Healthy dietary approach will alter the risk of CD as reflected by a decrease in the GRS.

The goal of this clinical trial is to evaluate the diagnostic potential of Artificial Intelligence-assisted Fecal Microbiome Testing for the diagnosis of inflammatory bowel disease. The main question it aims to answer is: • Is Artificial Intelligence-assisted Fecal Microbiome Testing a reliable screening test for inflammatory bowel disease? Participants will be asked to provide fecal samples to be analyzed with next-generation sequencing techniques. If there is a comparison group: Researchers will compare the diagnostic performance of AI-assisted Fecal Microbiome Testing with colonoscopy to see the correlation between the results of both interventions.

The role of intestinal ultrasound in treatment monitoring has recently gained increasing interest thanks to its non-invasiveness, cost-effectiveness and largely availability. Moreover, new ultrasonographic tools, particularly dynamic contrast-enhanced ultrasound (D-CEUS) and shear wave elastography (SWE) can provide further useful information, such as a quantitative estimation of bowel intramural microvacularization and tissue stiffness. Aim of this study is to evaluate the role of D-CEUS and SWE in predicting deep remission at 12 months from treatment induction in IBD.
