The postoperative recurrence of Crohn's diseases (CD) remains high. Stapled anti-mesenteric functional end-to-end anastomosis was safe for CD patients. Its impact on the postoperative recurrence of CD was unknown. Whether it is superior than the conventional anastomosis (stapled antimesenteric isoperistaltic side-to-side anastomosis) needs explored. The trial aims to compare the different impacts of the two antimesenteric anastomosis configurations on the anastomotic recurrence following bowel resection.
The investigators plan to compare contrast-enhanced ultrasound to CT and MRI for the detection and quantification of intestinal inflammation in the the setting of pediatric small bowel Crohns disease
Crohn's disease (CD) is a chronic disease with a heterogeneous clinical presentation, relapse rate and treatment response. Insufficient control of mucosal inflammation results in irreversible bowel damage and complications and at present no markers are available to predict such a complicated disease course at diagnosis. Therefore, to prevent overtreatment of low risk patients, step-up treatment with subsequent introduction of corticosteroids, thiopurines maintenance and TNF-blockers if a previous category fails is standard care. Combination treatment with thiopurines and a TNF-blocker is more effective than monotherapy but associated...
This is a data collection study that will examine the general diagnostic and treatment data associated with the reduced-intensity chemotherapy-based regimen paired with simple alemtuzumab dosing strata designed to prevented graft failure and to aid in immune reconstitution following hematopoietic stem cell transplantation.
The study is 3 arms observational study with no intervention that aims to understand the link between Crohn's disease, microbiome and diet in children. 150 children newly diagnosed with Crohn's disease will participate in the study and their data will be used to create an algorithm about their microbiome, disease, diet, etc. 100 other children newly diagnosed will participate in the study and their data will be use to validate the algorithm. The investigators will be recruiting 50 healthy participants: 20 that are undergoing an endoscopy for abdominal pain and 30 that comes to the physician for different reasons. After...
The overall goal of the study is to develop data that can convincingly guide clinicians on the use and efficacy of vedolizumab in patients with small bowel CD. There is an unmet need to identify response to vedolizumab in small bowel CD using objective endpoints. Current data suggest that MR enterography may meet this unmet need. There is an additional unmet need to develop predictive models incorporating both clinical and baseline radiological and endoscopic variables with higher discriminatory performance in identifying longer term clinical remission with vedolizumab. Finally, this proposal is strengthened by the exploratory...
Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD). Like other chronic diseases, patients with CD may be affected by other diseases called comorbidities. The prevalence of comorbidities in IBD patients ranges from 30 to 70 %. Unlike other chronic diseases, there is currently no CD-specific tool to assess the impact of comorbidities on patients' lives in order to take appropriate medical measures. Several clinical indexes have been developed for the study of comorbidities, including the Charlson index and the Groll index, which are widely used. The disadvantage of these indexes is that they are not adapted to patients...
Cded in remission patients with high calprotectin
The purpose of this study is to determine the effectiveness of a low-fat, high fiber diet (LFD) containing a minimal proportion of fat to improve gastrointestinal symptoms, quality of life and signs of inflammation in blood and stool.
Since 2009, many studies tend to prove the effectiveness of diffusion-weighted MR-enterography in the assessment of inflammatory activity in IBD compared to standard MR-enterography, with the emergence of new radiological scores such as the Clermont score. Diffusion-weighted MRI (DWI) is a faster technique and does not require the injection of gadoline contrast medium, which is a desirable in view of recent data on their long-term adverse effects (intracerebral deposits, nephrogenic systemic fibrosis). The advent of 3T MRI, which provides a better signal, a better spatial resolution or the same examination quality in a shorter...
